Engineering - Special - Diametrically Magnetized - 100pcs 3mm x 2mm (Approximately 1/8" x 1/16") Disc Magnets

Diametrically magnetized magnets made for rotating or swappable joints like miniature weapon arms, turrets, posable limbs, or anything you want to pop off and easily reattach.

The difference is in the poles. A normal disc magnet has north on one flat face and south on the other, so if you glue one in backwards it won't match. These have the poles on the curved sides instead, which leaves both flat faces neutral. Set one loose in a socket and it simply rotates until it pairs with its partner - no glue needed, and no keeping track of which side is which.

At 3mm x 2mm they seat in a snug 3mm socket with a little room to rotate; leave them free to spin rather than gluing them fast, so they can do their self-aligning job.

N52 neodymium rare earth magnets, so they pull several times their own weight. Good for anything you'd normally use Velcro, brass fasteners, hinges, or pins for.

WARNING: More brittle than glass, so don't let them slam together or drop them on a hard floor; they'll crack. Keep them away from anyone who might swallow them, kids or pets included, since magnets that get swallowed can pinch through the intestines and cause serious harm.
