User questions & answers

Question:	To what extent will this damage electronics? What is a safe distance
Answer:	This greatly depends on the electronic. Phones? You're fine as long as it's a newer phone from the last couple of years. This affected equipment with rotating hard discs. Most electronics these days that use storage will be using SSD which is unaffected by the magnet. It may damage a TV screen if it's literally attached to it. Keep it away from medical equipment but essentially it's okay around most electronics.
Question:	Can it hold a door full length door decoration - 2 ply w/lights inside it? Door is sewn material 2 ply and weighs about 15 lbs.thanks
Answer:	It will hold 15 lbs with no problem.
Question:	Can this magnet remove seal on oil pan eco-plug
Answer:	I doubt
Question:	Can you use this magnet to guide a metal plumbob inside a wall to a predrilled hole for fishing electrical wire from basement to attic
Answer:	If any metal in the wall it will stick to it. This is a very strong magnet and you may lose it in the wall if you use a cheap string...

User questions & answers

Question:	could i use these to keep a cover on my couch sticking them together
Answer:	They are only super powerful on one side. Not sure if that would work, but ine and a piece if steel clicked over the top should hold, I would say. Might rip the fabric though.
Question:	Does this set come with magnets and metal so I can attract to wood surfaces together
Answer:	It only comes with the wood screws as shown. I am not sure I quite understand the question, but one can obviously use longer screws if necessary, or use machine screws and nuts as I had to do to fix the magnets to a fiberglass sheet. - I used the magnets to secure a fiberglass sheet to a steel door, as I did not want to drill holes in the door.
Question:	What is magnetic holding power of each magnet? amazon description says "up to 90 pound holding power per magnet" but a previous q/a says 90 for set
Answer:	They can probably hold 90 ea. They are very strong
Question:	how long is the radius of the magnet
Answer:	One half the diameter or .630 inches, or .005 shy of 5/8"...studying for a math test?

User questions & answers

Question:	What is the actual size?...Anybody counter sink these with forstner bit?...If so, what size bit?..Thanks
Answer:	I used a 1.25" forstner bit and it was a fraction too small. Had to carve them out a bit too get the magnets to fit. These claim they're 1.26" in diameter and i believe that's accurate.
Question:	Is there a trick for separating them? I struggle to pull them apart
Answer:	I found sliding them off one at a time works best. Once you slide one off the top a couple of centimeters, you can separate them by pushing a thin piece of plastic between them - like a guitar pick or a tiddlywink.
Question:	Will they work with a 1inch piece of wood between them
Answer:	magnetic force dies off at the rate of about 1/r with r raised to the 4th power so the greater the 'r', the distance to the item attracted, then the attraction is reduced by a huge amount... Hold two magnets an inch apart and feel how week the force is between them, either attractive or repulsive, then try bringing them within an 8th of an inch of each other and see how the force increases!
Question:	Do they stand up to heat
Answer:	I use Neos on oil filters without a problem. Any fine ferrous material in the oil stops there. I use 1" dia x 1/2 thick 45lb pull Neos. (Strong enough to put on a closed steel tool box and pull tools to the top from the top tray inside the tool box.) No noticeable degradation in strength over 30,000 miles (car) 25,000 miles (water cooled motorcycle). As for actual temp, I would suspect much higher temp than what I run them at (180F or so), they would begin to lose their magic.

User questions & answers

Question:	Do they hold calendars on fridge
Answer:	these magnets are very strong and I think they will hold a calendar .. just hard to say without seeing the calendar but I am very happy with these!
Question:	Is one magnet strong enough for multiple sheets of paper at once
Answer:	Yes, the magnet is very strong, but not too strong to scratch the surface it's on while trying to remove. The magnet itself can hold several sheets of paper, or the magnet is strong enough to continue to stick while holding tons of paper in the clip. I have been extremely happy with the product and would highly recommend.
Question:	How wide are they
Answer:	The Papercode clip magnets are about 3cm wide. Thank you for your question
Question:	Are the magnets glued to the clip or held on another way
Answer:	The magnets are glued to the clip. Thanks for your question!

User questions & answers

Question:	What kind of magnet is good to hang heavy items
Answer:	many magnets are rated for weight required to remove them. you need a magnet that will hold 50% more weight than the object you are hanging
Question:	Do you think these would be heavy enough to keep a tablecloth from flying in the wind? (two stuck together with tablecloth in middle
Answer:	I would think so. If the wind is strong you could always use a bunch.
Question:	Could you use these for holding props on cosplay outfits
Answer:	I don't know but i don't see why not. They have a very strong hold.
Question:	Would these hold their magnetism if heated (like in an oven?). need it to shut an oven door. please answer if you know, if you don't, please don't
Answer:	Ceramic magnets can only take about 300F and lose 25% or more of it's at room temperature magnetism afterwards. For what you're after I'd use a 16lb+ pull magnet from a hardware store for the same price.

User questions & answers

Question:	Are these really N52!?! Thanks
Answer:	Probably. They come packed with spacers in between the bar magnets as can be seen in the picture. If you remove the spacers, you will have a hard time separating them from each other. They are incredibly strong.
Question:	How are these magnets polarized? Through the thickness
Answer:	I do not know the answer sorry
Question:	How do you prevent the magnet from the power dying
Answer:	My understanding is that it could take hundreds of years for rare earth magnets to demagnetize. I have not owned these magnets long enough to verify, though.
Question:	listing says 33lb but details say 12 lb which is it
Answer:	These seemed to be more on the 12 lb side even though the title suggests 33 lb and the details say 12 lb. Magnet-on-magnet was strong but alone it was pretty weak. I ended up returning these.

Product description

LOVIMAG Neodymium Cup Magnets



Rare earth magnets are the strongest type of permanent magnet currently made. They are amazingly for their size and have innumerable uses.

They are magnetized through the thickness. They are composed of neodymium iron boron magnetic material and are plated in nickel-copper-nickel for a shiny corrosion resistant finish. Maximum working temperature is 176 F (80 C).



Neodymium pot magnets are made of a powerful Neodymium magnet sunken in to a steel shell meaning that the north pole is on the centre of the magnetic face and the south pole is on the outer edge around it.

The steel pot increases the adhesive force of the magnets giving them an incredible hold for their size. An added advantage of pot magnets is that they are resistant to chipping or cracking following constant impact with a steel surface.

These magnets are countersunk on the magnetic face and can be fixed to a surface, pot magnets are also available with boreholes and threaded studs.

• VERY POWERFUL : Unbelievable Holding Power for the Size, Up to 60 Pound Holding Power per Magnet.
• VERY DURABLE: These Magnets will not Break in Normal Use since the Magnets are Protected inside the Steel Cups which Greatly Increase the Longevity of the Magnets.

User questions & answers

Question:	can they be used to hang speakers
Answer:	Yes, these magnets are strong for their size... depending on the weight of the speaker, you may have to use additional magnets...but it should work for you.
Question:	What is the stand-alone length of the screw? What is the overall depth of installed magnet, top to bottom? Must set flush in a 3/4" frame
Answer:	The screw is 1/2" To set flush in a 3/4" frame, place 2 1/16" washers behind the magnet.
Question:	How thick are these magnets? They say 1" dia but they don't state the thickness.. Please answer
Answer:	they are actually 7/32, which is a short quarter. 3/8 would be another 1/2 times as much.
Question:	Are these magnets strong enough to work though 3/16" thick thermofelt welding blanket
Answer:	These magnets are really strong for their size. They have as much holding power as some larger gun magnets I have. That said, the holding power through a 3/16 blanket (I tested on a normal cloth blanket of 3/16) is greatly reduced. If you are planning on using them to hold the blanket up against something you may not get the result you want. I suspect a welding blanket is pretty heave - so if the magnet is on a shear the blanket will likely slide. If you used lots - like all 12 - and selected your application you might be OK. Also, note the shape - the flat side is the usable side - the rounder looking side has very little power. This is relevant to removing them without the screw in place - very difficult when magnet is directly in contact with ferrous metal. You would have to slide it to a point allowing you to get it loose. Also - no way these things hold 60Lbs. I could not pick up a 30Lb dumbbell. Maybe some types of iron/steel are more attracted but I don't see 60Lbs. That said - these are about 1 inch by 3/16 and very solidly hold ferrous items I have that weigh 4-6 lbs.

User questions & answers

Question:	Was thinking of using these to hold up some art from Displate. Will these work in drywall too or should I get different screws
Answer:	I used machine screws for my need. These are very short wood screws and would not hold well in drywall. Use longer drywall screws or other suitable mounting hardware. The magnets are extremely strong and quite adequate for my application.
Question:	What’s the thickness of each magnet
Answer:	I'm guessing half an inch.
Question:	Polarity: I'm looking to build a permanent magnet motor rotor, and one magnet needs to have North pole out & next magnet to have South pole out
Answer:	I got 50 of them and pretty sure they were all polarized the same. I didn't see any way to turn them over to reverse polarity. look for something different, or if you need a lot, maybe the manufacturer can custom make.
Question:	How thick are these (I've seen 1/4" and 1/2" answers), anyone take a measurement with calipers to get an exact measurement
Answer:	7.02mm x 32.16mm. I eyeballed it... jk... Measurement taken with calipers as requested.

User questions & answers

Question:	Would this magnet be good for destroying an old hard drive
Answer:	No, the most effective way to destroy an old hard drive is death by fire! If you disassemble the old drive you will find two very powerful magnets inside.
Question:	Can this be used to wipe the information from a hard drive? No guesses, please
Answer:	No
Question:	Do you think this could be used to pull wire under a carpeted area
Answer:	The other issue about using this product to pull wire, is that the wire is probably either copper or aluminum. A magnet won't help you with wither of those. Using a fish tape (steel) you may help guide the tape with this but probably not "pull" the tape under carpet.
Question:	Surely this can be used to find studs in the wall at home by sticking to the nails or screws in the wall correct
Answer:	I used it exclusively for picking up women. If you have men trapped in your walls you may want to hire a contractor and alert the local news.

User questions & answers

Question:	How did they do on magnetic paint
Answer:	They are super strong and stick to just about anything - even THROUGH the box. If you are looking for magnets for kids/classrooms, find something less intense. I have to store these in the styrofoam casing and box they came in and stuff STILL sticks to them. They have a special place in my house so they won't interfere with electronics because they are STRONG. But yeah, should be great on magnetic paint. But they are VERY thin and break easily
Question:	Will these hold a cloth curtain to a metal shelf
Answer:	It depends on many factors, like the metal the shelf is made of, and how heavy the curtains are. I believe these magnets could probably manage it as long as the shelf isn’t super skinny materials or aluminum. The I find the name of these magnets to be accurate. They are pretty powerful and can probably do the job.
Question:	What grade are these magnets? They don't seem strong enough to be n52, and the grade is conveniently left out of the description
Answer:	Hmmm, I’m pretty sure that these are N52. Just keep in mind that one disk is not big, so it’s magnetic field will be relatively small. If you combine the disks without any spacers, you will see the force greatly increases to what I believe is appropriate for N52. I have never measured the grade of a magnet, but I know that these are not weak compared to toy magnets.
Question:	Has anyone that purchased these used them for diy spice jars? (specifically, is the strength appropriate? ie: not too strong or too weak
Answer:	I am going to use these for this purpose. Here's why: a standard ceramic magnet can stick to another magnet with a pretty strong pull, but on a metal surface it is much weaker. These are VERY difficult to pull away from each other, but I imagine it will be much easier to pull a spice jar off the fridge, since the fridge is not a magnet. They also provide enough strength that I am not concerned about a glass spice jar falling off the fridge.

User questions & answers

Question:	Will it turn electronics behave erratic if put in close proximity.? I want to stop digital electric meter
Answer:	Hasn't for me .
Question:	is this a n52 grade magnet
Answer:	I believe it is
Question:	Can i use it for instrument dent removal
Answer:	It may be too strong so try it on sometime first
Question:	Can someone recommend magnets to be mounted and towed behind a small boat to cover more area? Thank you
Answer:	Generally towing behind a boat is not the best way to use fishing magnets. The magnet has to be within inches of the object to snag it. If you tow it behind a boat it will bounce along the bottom and miss a lot of objects. Best way to use magnet is to toss it out and slowly retrieve. This way you can feel a bite and get the best hook up. If you are on a boat you can bob the line up and down while drifting.

User questions & answers

Question:	I want to get these to hang on my sons wall to store his matchbox cars, will these work
Answer:	These are tremendously powerful magnets. I use these to hold my knives to the fridge, through wood veneer. They would probably be overkill for matchbox cars, and some cars are not magnetic at all and would not work.
Question:	Do these magnets come with the adhesive strips attached? I know they're fragile and I don't want to have to remove the adhesive
Answer:	No, but they’re still hard to separate because they are very strong magnets.
Question:	Would the magnets work to hold a bug screen to a steel security door? Putting screen against door and magnet on top of screen
Answer:	Yes it would as long as the frame is metal but the magnets are very strong so it would work well for the opening of the screen because they hold so strong it would be a haste going in and out of it but not bugs will get in 😂
Question:	Are these magnets or magbets as described on the picture with the tools on them
Answer:	LOL! They are magnets until you want to use one to hang up a heavy, expensive tool. Then they become magbets as you magically bet and pray that they are as strong as advertised and securely hold your item up. :-)

DIYMAG Neodymium Block Magnets - 60mm x 10mm x 3mm (25 PCS)

How to Safely Seperate Your DIYMAG Magnets?

OUR FACILITIES

We never compromise on quality and all our products are performance tested using a computer controlled tensile and compression machine. The system accurately measures the weight a magnet can hold when pulled vertically and the amount of pull a magnet can exert when there is a gap or non-magnetic material between the magnet and the material it is applied to attract. Using the best technology, we make sure our customers always get the correct magnet for their application.

Product description

Practical Design

This magnet was specifically designed with magnet fishing in mind. Our magnets are made of high-grade Nd-Fe-B materials.

Neodymium magnets are the strongest type of permanent magnet currently made. They are amazingly powerful for their size and have innumerable uses.



Data based on scientific measurement

Pulling Force: 95 lbs

1. We used A3 high quality steel as the test floor.

2. After many measurements, we have obtained scientific and rigorous measurements by pulling the hook at a uniform speed on professional equipment.



Several Important Factors Affecting the Tensile Force of Magnets

1.Only when the thickness of the tested steel reaches a certain level, the magnetic flux through its cross section would be the largest and the leakage magnetic field between the magnetic poles is

the smallest, the tensile energy can reach the ideal value.

2.Only when the force is perpendicular to the contact surface can the tension reach the maximum. When the force is parallel to the contact surface, the pulling force can only reach 1/3 maximum.

3.Magnets attract only magnetizable materials such as iron, cobalt, nickel and their alloys. It can not attract non-ferromagnetic plates such as aluminum, copper, wood, plastics and stainless steel.

4.The farther the magnet is from the magnetic material, the greater the leakage magnetic field and the smaller the pull force would be. Therefore, the surface paint adsorbed by magnets is also an

important factor affecting the pulling force of magnets.



WARNING

1.Keep away from pacemakers.

2.Powerful magnets can hurt your fingers.

3.Not for children, parental supervision required.

4.Please wear a pair of gloves when you handle them for your safety.

5.All magnets may chip and shatter, but if used correctly can last a lifetime.

6.The maximum working temperature of neodymium iron boron magnetic is 176 F (80 C)

User questions & answers

Question:	Are these magnets strong enough to work though 3/16" thick thermofelt welding blanket
Answer:	I do not think so.
Question:	It says pulling strength about 95lbs. Is that per magnet or collectively
Answer:	I would suggest collectively. I use mine in a metal tool cabinet to hang tools on, but nothing as heavy as 95lbs and they work great, very solid.
Question:	I want to use these to hold mosquito netting to the outside of my rv sliding door. are the magnet bottoms totally flat? i want to make sure they will
Answer:	I'm holding 4' led lights up in a container no problem make sure attachment points are magnetic !!!
Question:	What thread is used between the magnet and the eye? (If you don't know, please just don't answer
Answer:	The thread is M4.

User questions & answers

Question:	would they work well to keep a flag from rolling up in a wind
Answer:	You may them as a weight added on the bottom corner of the flag. Just try it.
Question:	What strength are these magnets?! N52,N45 or what
Answer:	I'm not too knowledgeable about N52 or N45 strength, but I do know that these magnets are so strong that I have an 8x10 plaque that I hung on my metal door and I used 3 magnets and I now can't get that plaque off the door, which is good cause I didn't want the plaque to come off anyway, but I should have used 1 magnet and that would have held it. I believe that each magnet can hold up to 20-30 pounds, they are very strong! Hope this was useful.
Question:	I’m making a knife display case I’m wondering if these can be used for that
Answer:	From a magnetic standpoint, they are definitely strong enough for that purpose. I hold a rattling license plate on a moving vehicle with one of them. It’s rock solid. One of these magnets will hold the average hunting knife. Larger blades might need two. The only concern I have are the adhesive pads. They are quite good, but how long will they last is anybody’s guess. After a few years of heat and humidity variation, you might find yourself in a falling knife situation. Worst case you could use two magnets, one on either side of your case back plate. The magnets will hold each other against the plate and the knife as well.
Question:	I want to stick my desk to my wall so it stops wobbling. Do these magnetics stick together and stick onto non metallic surfaces
Answer:	These magnets are ridiculously strong. So strong it will be hard for you to pull them apart. They also break easily. I would not use them for a desk.
