This 25x2.5mm (1x3/32") delivers a 10lb (4.5kg) holding force in a small space. Build your own wall mounted tool holder or organizer for safe & easy access to wrenches or knives.

We have sold NdFeB magnets since 1996 and N42 grade since 2003, the best value for strength & temperature vs cost. Don't be fooled by claims of higher strength, N52, at lower cost.

It was ordered to test the theory that Covid-19 vaccines had made some people to be magnetized. The two I have checked have not proved to be so. The little magnets work very well. The only thing I would suggest is to be more explicit in warning about staying away from TV, computer, etc. with respect to actual distances recommended.

The danger to electronics is meant to be a general one. A tiny magnet up close will have no effect. A big one right up against a hard drive or monitor can cause some grief.
