2 Types Of Magnets
Permanent magnets: These magnets are made of materials that are naturally magnetic, such as iron, cobalt, nickel, and some rare earth metals. They retain their magnetism even after being removed from a magnetic field.
- Product Introduction
There are two main types of magnets:
1. Permanent magnets: These magnets are made of materials that are naturally magnetic, such as iron, cobalt, nickel, and some rare earth metals. They retain their magnetism even after being removed from a magnetic field. Examples of permanent magnets include refrigerator magnets, speaker magnets, and the magnets in hard drives.
2. Electromagnets: These magnets are created by passing an electric current through a coil of wire. The magnetic field is created by the flow of electrons in the wire. When the current is turned off, the magnetic field disappears. Electromagnets are used in a variety of applications, including in motors, generators, MRI machines, and lifting devices.
