China N45h Rare Earth NdFeB Round Arc Motor Magnet

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.
Every permanent magnet generates a magnetic field, which circulates around the magnet is a distinct pattern. The size of the magnetic field is related to the size of the magnet and its strength.
