the most magnetic naturally occurring mineral or neodymium, Samarium cobalt, a powerfully magnetic synthetic substance.The Earth itself is a huge permanent magnet, though its magnetic field is quite weak relative to its size.Humans have used the magnetic field of the Earth for navigation since the compass was invented in ancient China.Even the most powerful permanent magnet is not as strong as the strong electromagnets, so their applications are limited,but they still have very widely application, magnets can be found everywhere,including your hard disk, ATM and credit cards, speakers and microphones, electric motors, and toys.
