B-H Magnetization Curve and Hysteresis Loop

Saturation induction depends only on the ferromagnetic atoms present in the materials and is not structure sensitive. 

When the external magnetic field is decreased, the magnetic induction follows a curve with higher values than the original curve owing to the irreversibility of the walls motion. 

B = 0). The initial slope of the B-H curve is called the initial magnetic permeability and
