Hysteresis Loop

The hysteresis loop indicates the relationship between the intensity of magnetization and the magnetizing field. This loop is generated by measuring the magnetic flux that is coming out from the ferromagnetic substance while changing the external magnetizing field.

Advantages of Hysteresis Loop

1. A smaller region of the hysteresis loop is indicative of less loss of hysteresis.

2. Hysteresis loop provides a substance with the importance of retentivity and coercivity. Therefore the way to select the right material to make a permanent magnet is made simpler by the heart of machines.

3. Residual magnetism can be calculated from the B-H graph and it is, therefore, simple to choose material for electromagnets.
