What is hysteresis? Draw a hysteresis loop for ferromagnetic material and explain various important parameters. A magnetic material has a magnetization of 2300 A/m and produces a flux density of $0.00314 wb/m^2$. Calculate magnetizing force and relative permeability of the material.

Hysteresis:

• Hysteresis is the dependence of the output of a system not only on it current input, but also on its history of past inputs.
• The dependency arises because the history affects the value of an internal state.
• To predict its future output, either its internal state or its history …
