Magnet, Ring

These ring magnets are strong, made of a ceramic material, and have a unique alignment to them. Imagine a line of donuts that have a north pole on one end and south on the other. Once the line is sliced, the individual pieces of the magnet will still have the north pole on one end and south on the other.
