Super Strong 2 Inch OD x 1 Inch ID x 1/4 Inch – N42 Neodymium Ring Magnet | Powerful Rare Earth NdFeB Magnet for DIY, Industrial, and Craft Applications Applied Magnets®

strong magnet, it worked prefect for resting my TPM sensors on my jeep and much cheaper than what they want to buy from the dealer or anywhere else.

Powerful magnet!

This magnet was extremely strong. I say was because I had brain fast and allowed it to get near larger magnet. It flew through the air, hit the other magnet and shattered into pieces.I want to stress Grade N52 Neodymium magnets are extremely brittle. I knew this but didn't pay attention.Always keep this in mind because the tiny pieces can fly everywhere and are very sharp. These could definitely injure your eyes if this happens.Now as far as quality of the magnet, Applied Magnets that I have always bought were strong and good quality.

BEST Best best solution to reset the TPM - 2002 Corvette ... these worked great - had new tires put on my 2002 Corvette - love the guyz over at my local Discount Tire - but - they didn't reset the TPM correctly - result was - my TPM warning system was popping up advising there was a monitoring issue with the TPM system - quick check on the Corvette Forums - advised just to re-set the TPM's on each tire - just follow the directions in the manual (if you have one) - in my case I dug up the procedure from the Corvette Forum - anyway - these are the PERFECT size to just drop over the air valve assembly & strong enough to reset the TPM on each wheel (note - you just need ONE magnet & walk around the car - again - just follow the procedure that's on the Corvette Forum site) - turns out the $200+ actual GM "tool" - is just a magnet anyway - so for one-tenth the cost - get a couple of these (they make playing with 'em fun - but be careful - or you'll get a nasty pinch as these magnets are SUPER strong) ...

Nice

Incredibly strong for size the are robust so don't crack or snap easily good quality magnets.

Just got these. They came with warnings about the strength. I said "Sure, real killers". Well, it took a lot to remove one from the stack and there is a nylon or plastic spacer holding them apart. Pretty cool I thought. When I started to put the (now) single one down about 6" from the stack it flew out of my hand to the stack and broke about 1/4 of itself. I have to figure out how to remove it now. These guys are absolutely correct with the warnings so please read and heed. I love these but maybe they are too strong for my uses but with a non magnetic hunk of something I can tailor their pull to meet my needs. I usually blow off warnings but not so with these. If you need killer magnets these are the way to go.

Experimenting to design a frictionless static magnetic bearing. So far it looks promising.
