Engineering-Special - Diametrically Magnetized - 50pcs 3mm x 6mm (Approximately 1/8" x 1/4") Cylinder Magnets

Rare Earth magnets are the strongest magnets in the world.  These magnets have pull several times their weight. These diametrically magnetized magnets are great for inserting in cylindrical holes that don't need glue since they will self align with another diametrically magnetize magnet. Most magnets have a north pole on one flat side and a south pole on the other flat side of the disc magnet, this prevents magnets from flipping to match if inserted into a part. Diametrically magnetized magnets have a north pole on the curved side of the magnet and a south pole on the opposite curved side of the magnet, leaving each flat side with a north and south pole. If they are allowed to freely rotate in a socket they will rotate and pair with another magnet.
