permanent magnet
- Definição1
- A piece of magnetizable material, such as hard steel, that has been exposed to a strong magnetizing force. This force aligns the spin axes of the electrons surrouding the atoms of the material, and thus the magnetic domains within it. When the material is removed from the magnetic field, it is magnetized and the domains remain in alignment until a strong demagnetizing force is applied.
