Product Description

Ring magnets are used in a variety of applications, from science experiments to medical equipment, because of the versatility of their shape and their ability to work with other components, like rods or tubes. Ring magnets have a unique polarization because the north and south poles can be segmented in a variety of ways, but always alternate around the ring. 
A permanent magnet is that a magnet that is permanent, in contrast to an electromagnet, which only behaves like a magnet when an electric current is flowing through it.
Permanent magnets are made out of substances like magnetite (Fe3O4), 
The most magnetic naturally occurring mineral or neodymium, Samarium cobalt, a powerfully magnetic synthetic substance.
