Question

Define magnetization. Explain any one method to magnetize a material.

Answer 1

1. The process of magnetizing a material is called magnetization.

Electric method:

1. A magnet made by passing an electric current is called an electromagnet.
2. When the current is stopped they stop behaving like a magnet.
3. They are temporary magnets made by this method.
4. If materials like steel and special alloys are placed in a coil and a very high current is passed through the coil, then electromagnets can be made permanent magnets.
