User questions & answers

Question: Can this open a sentry safe
Answer: This is a pretty strong magnet that Would definitely pick up sewing needles. You might have trouble taking the needles off.
Question: How do the N-ratings work? Are the higher N numbers the stronger ones
Answer: As I remember it was wrapped in bubble wrap and then in a box. If you order more than one, they have a plastic separator. I don't think it's dangerous to electronics unless it's right up against it, so the packaging keeps it far enough away to prevent that sort of problem.
Question: Will any of these magnets pick up small sewing needles
Answer: No , this is not the stat for that system. We recommend you stay within the Nexia product group.
Question: what kind of packaging do you use to ship these magnets? are they considered 'dangerous goods
Answer: Yes , same unit - functions exact same...just a different logo on the surface of the stat

User questions & answers

Question: Will they stick to ceramic tile on outdoor patio to hold screen curtain in place
Answer: Thanks for question. No adhesive foams are not attached to magnets. there are plastic gaskets between magnets and box includes extra adhesive foams. if you would like to use adhesive, you can remove their papers and use adhesive foams with magnets or other DIY project.
Question: are these magnets strong enough to cling to one another if there is canvas material between them
Answer: Maybe you want to stick the magnet to something non-magnetic, so that you can THEN put that non magnetic something on a metal surface. For example, you want to stick a dry marker board on your fridge, but the dry marker board is aluminum (non magnetic) the adhesive allows you to stick the magnets to the non magnet board.
Question: Is the adhesive attached to the magnet before shipping
Answer: Yes. This will most certainly open a sentry safe. However, you will have to purchase two of these In order to cut down on time before the cops come.
Question: So i can use the bar magnet without adhesive? what is the adhesive for anyway if these are such strong magnets? i do not need adhesive. just magnet
Answer: The N-Ratings are a complicated mathematical formula that takes the “pulling force” as it relates to the surface area in contact with the object being pulled. That being said N-52 is the strongest possible. I own a N-52 and I own THIS exact magnet. I can barely tell the difference between them! So either the N-52 I bought was not really N-52, or there is not THAT much difference between them at 1 square inch?!

So the pulling force of the product is higher than other products of the same size. . Data based on scientific measurementPulling Force: 100 lbs1. We used a 1. 5 cm thick 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 Magnets1. 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 isthe 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 animportant factor affecting the pulling force of magnets. WARNING1. Keep away from pacemakers. 2. Powerful magnets can hurt your fingers. 3.

User questions & answers

Question: Can these hooks be joined together back to back
Answer: Don’t fully understand the question. If you mean one hook on one side of metal object & another on the opposite side of metal object, the answer would be yes. If you mean back to back of each other, yes. They are very powerful magnets. I have a ladder hanging on the side of metal building with only 2 hooks. Very useful to have, I keep buying them to hang all sorts of things in my metal building
Question: will these magnets hurt tablets or phones
Answer: These are better suited for the shop......i would not stick a magnet to an electronic device.
Question: will they side off the stove or refrigerator
Answer: No. As long as it’s metal, you should be fine. However some newer ovens have a glass cover over the front. Mine does. The magnet did stick but the glass caused it to slide down.
Question: I plan on using this as a temporary way to hang decorations. How difficult is this to pull off
Answer: If the wall you are putting the hooks on is metal, yes they will hold decorations. I use them on cruised ships and are very satisfied with their strength and ease of removing.

User questions & answers

Question: why won't my magnet pic anything off the bottom of a lake
Answer: To clarify, will the adhesive stick to ceramic tile, I say yes, but... the magnets are strong. I used the adhesive to attach the magnets to a small clipboard on my refrigerator. Pulling the clipboard straight off the fridge for several months, the magnet stayed on the fridge. I used a stronger adhesive to reattached the magnets to the clip board and that solved the problem. I would imagine if your patio gets any heat, the adhesive may not hold. I think it may also depend on how thick your curtain is. These also hold a double thickness (folded once) terry cloth hand towel to my fridge.
Question: Is the eyebolt threadlocked, or otherwise prevented from unscrewing
Answer: Thanks for question. Canvas is dielectric material so it will decrease magnets strength. if canvas's thickness is too much for magnets, there will be no pull force between magnets.

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: 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: What is the maximum operating temperature
Answer: The easiest way to tell is to put the magnet next to a compass. The arrow on the compass will be strongly attracted to the South Pole of the magnet.
Question: Idea: if i glue one of these into a wiha 26563 would it work to hold a 1/4 scrwdriver bit and turn this wiha unit into a 1/4 precision mag bit holder
Answer: Sorry, I am not familiar with the meaning of “n52”! These magnets are very,very tiny and very,very powerful! Without a doubt, these itty bitty magnets are the strongest I’ve ever seen!
Question: How do you tell the difference between north and south poles
Answer: Hello,dear customer,Our adhesive strip is placed separately, not directly attached to the magnet
Question: Are these n52 magnets
Answer: Ferrous metals/materials are the only objects that are physically attracted to magnetic fields. Ferrous metals are very common due to the heavy use of iron in most metal alloys. Ferrous metals contain a large enough iron content to create enough domains for a magnetic field to act on and attract. Aluminum (weekly), gold, copper are not magnetic. Iron, cobalt and nickel, as well as alloys composed of these ferromagnetic metals, are strongly attracted to magnets. Other ferromagnetic metals include gadolinium, neodymium and samarium. Paramagnetic metals are weakly attracted to magnets, and include platinum, tungsten, aluminum and magnesium.

User questions & answers

Question: Strong enough to hold comforter to a duvet? even if comforter is on teh thin side, will it be really secure or keep opening and defeatin the purpose
Answer: Thanks for question. Neodymium magnets have different grades such as N35, N45, N42 or N52. Grade means measure of the strength of a magnet. Higher grade numbers indicate a stronger magnet. How does it compare to N35? If you need the highest strength in the smallest possible package at room temperature, grade N52 is the strongest available in the industrial magnets. The given link product has N42 grade which is lower than our magnets' grade. Pull force is how much force you have to pull on a magnet to move it away from something, such as a steel surface or another magnet. In general higher pull force is better. If you want to separate magnet from a steel plate, you need pull force 7.78 lbs for 1.26 diameter and 0.08 thickness N35 grade and with same size N52 magnets pull force is 11.56 lbs. You can find a lot of magnet pull force calculator on internet.
Question: Could I use a few of these to attach foam board "wings" to a costume
Answer: For you? No. Sorry.
Question: What is n52? how does it compare to n35? or specifically these magnets: https://www.amazon.com/gp/product/b072kdbjwc
Answer: Great question! The maximum operating temperature is 176 degrees Fahrenheit.
Question: Will these magnets increase my sex appleal
Answer: It should work. I tried one in one of my 1/4" nut drivers and it fits just fine. Remember that you will lose 2 mm of socket depth + glue thickness, so make sure that there is still enough socket depth left to provide a good grip on the 1/4" inch bits that you plan to use.

User questions & answers

Question: I would like this to hold a desk drawer closed. But I have to be able to open it without the adhesive coming loose. Will these work
Answer: Thanks for question. yes you can cut magnets with side chisel or nippers. all parts will be still magnets. but be careful about broken magnets sharpness. it can hurt your fingers.
Question: I would like to use these to secure an outdoor patio screen curtain to tile. would be exposed to weather, heat, moisture. will they work for this
Answer: Thanks for question. Adhesive foams are not attached to magnets. they are separated from magnets. if you want to use adhesive foams with magnets, just peel paper on adhesive foams and paste to magnets or other materials.
Question: Can these be cut? If so, how
Answer: What is the purpose? Hold a comforter to a duvet how?
Question: Is the adhesive side magnetized? I want to use them on the front side of a garage door banner to attach the banner to the metal garage door
Answer: Thanks for question. Foam board is dielectric material so it will decrease magnets strength. if foam board thickness is too much for magnets, there will be no pull force between magnets.

User questions & answers

Question: Can this be used in sand
Answer: The magnets are very strong. If you were planning to keep the curtain closed permanently they would probably work, but if you plan to open and close them regularly they are hard to get apart. Also if they fall they break. They are very thin.

Master Magnetics Adhesive Magnets | Nickel-Plated Strong Magnetic Fastener | Double Sided Adhesive Foam Backing | 3” L x 0.905” W x 0.25” H | 8-Pack | CA293WAX8

Master Magnetics, Inc.

Based on 1 reviews Check latest price

Product description

These Magnet Fasteners by Master Magnetics are extremely versatile. Use them to latch cabinet doors, hang signs, and mount a variety of other objects in the home, shop, or office. Each device is assembled from a nickel-plated steel channel and a ceramic, ferrite magnet. On the side of the channel opposite the magnet, there’s a strip of double-sided adhesive foam. These fasteners can be used like industrial magnetic tape, but they’re much stronger. Each magnetic fastener has a flat base of 3” by almost 1”. The sides are a quarter of an inch thick. Because of their low profile, they’re inconspicuous and suitable for use inside the home. They can be used to hang art pieces from the wall or secure curtains in place. The heavy-duty ceramic magnets have a strong pull of 22 pounds on contact. This magnetic pull was determined by a vertical test. The pull is about 50% less when used on a vertical surface holding against a sliding force, and slightly less when used on painted steel. Whether attached to a refrigerator, a metal toolbox, a vehicle, or an industrial shelf, these magnet fasteners will hold tight. This economical package contains 8 magnetic fasteners, which means that you’ll have plenty of magnets for different purposes. Master Magnetics, manufactures and distributes magnets and magnetic devices for commercial, industrial, and consumer use. The company, founded in 1976, is headquartered in Castle Rock, CO.

User questions & answers

Question: Would the adhesive withstand 650 degrees fahrenheit
Answer: I'd add that at that temperature, many/most magnets will demagnetize (some ceramics do so as low as 400F).
Question: Trying to hang large gator board maps on a metal wall. The boards are warped a little. Would these magnets work to hang on metal wall
Answer: I'm not sure what gator board is but these magnets are pretty strong. I use them to hold hand guns to the inside of my safe door. It holds my .380 through the holster.
Question: Is this too strong to be used to a house screen door stays shut? My dam cat can open it with her face... help
Answer: The magnets are very strong. I stuck one flat to my locker at work and ended up using a screwdriver to pry it up enough for me to pull it off the rest of the way with my fingers. The sticky side is pretty decent but the stickem will definitely pull off before the magnet lets loose. I think this size might be a bit much to keep a cat from opening a screen door but it could work. How convenient it is for the people using the door might depend on where on the door you put it. If you put it near where the door latches one of these might work. I wouldn't not use more than one unless you really want the door to be difficult to open.
Question: What's the internal/external gauss
Answer: I don't know what 'gauss' is, but if you want to know whether they stick or not I had to slide them over to the edge of the refrigerator to take them off.:)

User questions & answers

Question: Is it N52 or N35? Seller says both, can't be right two ways
Answer: N52 grade
Question: Will this magnet unlock a sentry safe
Answer: With this thing you could unlock Fort Knox. I suggest getting two or three of them and stacking them together you can do it in much less time.
Question: Will it take off the sensor on clothing
Answer: Prob not. I let the cashier do that when I pay for the clothing with the added advantage of walking out of the store vs. running from the cops when the magnetic alarm goes of attached to the unpaid clothing. But hey, its really up to you.
Question: Will it wipe a hard drive
Answer: The strength of a magnetic field fades very quickly with distance. Considering the metal case of a hard drive and internal spacing, consumer magnets probably would NOT damage a hard drive. Way back in time, when 3.5 inch floppies were available, I passed an office magnetic clamp over the plastic case of the floppy. No data was damaged. I placed the magnet directly on the media through the access slot and data was damaged. Although the magnet I used was not as strong as a rare earth magnet, the experiment shows that the magnet must be very close to have an impact.
