• Some important points about this unit :- 

1) This chapter deals with the origin of magnetism, In this classification of

magnetism is based on permeability.

2) It covers many magnetic objects such as transformer core magnetic storage and

magnet optical recording.

3) On the other side, information is given about superconductivity and in this the

characteristics of super conductivity are given.

4) It contains information about zero electrical resistance, critical magnetic field,

persistent current, etc. and its applications.

5) Type one and type two superconductors are given and their structure and

diagrams are given.
