What is hysteresis loss

Definition of Hysteresis loss:

Heat is produced by the magnetizing force working against the internal friction of the magnet molecules. Hysteresis loss is the amount of energy wasted as heat as a result of hysteresis.

When current supplies are in the forward and reverse directions, hysteresis loss can occur due to the magnetization and demagnetization of the core. The molecules of the magnetic material are aligned in one direction when the magnetization force is applied within the magnetic material. This force can be reversed by the internal reflection of molecular magnets resisting the reversal of magnetism, resulting in magnetic hysteresis. Internal reflection can be avoided by utilizing a portion of the magnetizing force.
