Basic concepts of permanent magnets
- Mar 20, 2018 -

Permanent magnets, which can maintain their magnetic properties for a long time, are called permanent magnets. Such as natural magnetite (magnetite) and artificial magnets (al - Ni - Co alloy) and so on. In addition to the permanent magnet magnet, electromagnet has the required power is magnetic. Permanent magnets are also called hard magnets, which are not easy to lose magnetism and are not easy to be magnetized. But if the permanent magnet is heated over Curie temperature, or in the environment with high reverse magnetic field intensity, its magnetism will decrease or disappear.
