Question # 1
Distinguished between soft magnetic material and hard magnetic materials.
- Ans 1: Soft magnetic: The materials in which their domains can be easily orientated on applying external magnetic field and also return to original positions when field is removes.E.g iron.
- Ans 2: Hard magnetic:The material in which their domains can not easily orientated on applying external magnetic field.But once the domains are lined up by a very strong magnetic field,they will restrain their position after the removal of magnetic field.
