FINDMAG 20 Pack Neodymium Magnets Strong Neodymium Disc Magnets with Double-Sided Adhesive, Powerful Permanent Rare Earth Magnet for DIY, Building, Craft, Office - 1.26 inch D x 1/8 inch H

I bought these for my under cabinet lights. The magnets that came with them were not very good and my lights kept falling off. They are staying firmly tight with these magnets

I use my flat magnets for crafting. It holds my project firm on my magnetic work space so it stays steady when needed. Also use the magnet in my Misti stamping base for added protection from moving/shifting while stamping. I do recommend.

I recently purchased the Neodymium Disc Magnets for my daughter's physics project, and they exceeded all our expectations. These are not your average magnets; they are extremely strong and offer an impressive range of applications, as we discovered firsthand! You need to be careful to not pinch your fingers because of the strength.The task was to create a speaker from scratch, and thanks to the exceptional strength of these Neodymium magnets, the project was a resounding success. In fact, her speaker was the only one in the class that could be heard from across the room, a testament to the remarkable power of these magnets. In fact, the Physics teacher told my daughter this was the best speaker he'd heard in years and asked to keep the speaker for future classes as an example but was worried because he thought the magnets were $40!The Neodymium Disc Magnets are also wonderfully compact. Despite their strength, they are small and versatile enough to be used in a variety of contexts, from science projects to household tasks.Another aspect worth noting is the quality of the product. The magnets are well-made, durable, and have shown no signs of wear and tear, even after being put to the test in a rigorous project.The Neodymium Disc Magnets are an excellent purchase for anyone in need of strong, reliable magnets. Whether for a school project, like in our case, or any other application requiring a powerful magnet, these Rare Earth Magnets are up to the task. I cannot recommend them highly enough. They turned a physics project into an unforgettable success story and, for that, they have earned my highest commendation!

These are not 1.26" x .125". They are 1.16" (1 1/16, or 29.5 mm) x .109 (7/64, or 2.78mm).I would sure like to see this vendor update the dimensions to the actual value. It matters to many people and makes the vendor sound unreliable. That said, there are worse inaccurate magnet descriptions on Amazon.I did not measure the actual pull, but it can be very strong or fairly weak depending on how they are used.For instance. I have an electronics clamp meter that I have, using one magnet. It weighs about a pound. If you attach it vertically on the wall of an A/C unit, it will slip right off. That also goes for the textured side of my refrigerator. If you attach a piece of the open rubber mat used for lining drawers, it will stay put just fine due to the friction of the rubber. The face of the magnet is very smooth and has virtually no friction. That is why this vendor, or any vendor, tells you to slide them apart.Position: If the magnet is in a horizontal postition, it will not move, even without adding the rubber mat. It cannot slide down. It's pull strength is far greater than when it is used on a vertical surface. That is, on top of, or under, a metal surface.Breakage: all neodymium magnets are brittle. These are only a little over 1/10" (2.8mm) thick. if you buy double this thickness, they will be considerably more powerful and less likely to break. You can improve the tendency not to shatter and break a few ways. One is to use in a metal or plastic cavity about the same size as the magnet. Or double up with a metal washer in between. Or glue to a surface. Anytime they are loose, they will easily get out of control, and smash together and break.You can also coat the magnets with something like Rustoleum or Plastidip rubber tool spray or paint on the dip version. It will add breakage strength, rust proofing, and improved friction.The adhesive disks: These included disks are the weakest 3M double sided adhesive. The red adhesive (I think 3M 9737) are much stronger and resistant to heat. Gel, not the thin type, CA (cyanoacrylate, Super Glue) is also a better choice if you have things falling off the wall because the disks break loose.I was a bit dismayed at first when I tried to be careful, but ended up breaking a couple of these. Other magnets like this, but much thicker, do not chip or shatter as easily, but they were considerably more expensive.I have ordered these twice, because if handled and implemented correctly, they are a decent value.

Not much to say, strong and can be dangerous

These are super strong and you should be careful because they snap together so easily and then it was difficult to separate without the spacer. If I need more magnets I’m getting these!

...but the adhesive is not.One came off after one day. I used this for the 2nd screen for my laptop.

These magnets are great! I ordered them to add to a “no soliciting” sign for our front door. I used two for stability but I really think I could have gotten away with only using one due to how strong the hold is.
