Difference between eddy current loss and hysteresis loss

Definition of Hysteresis loss:

The hysteresis loss: The hysteresis loss occurs in the transformer is made of the CRGO steel which is a type of ferromagnetic material. The ferromagnetic material is made by the small atomic magnetic moments. When no field is applied to the material, in that case, the molecules are randomly arranged in the substance.

Definition of  Eddy current loss:

We all know that the eddy current induces in the core of the transformer when the alternating flux links with them. The flux induces the EMF in the core because of which the circulating current develops. The circulating current causes losses in the terms of heat which increases the temperature of the coil.

The most significant difference between the eddy current and hysteresis loss is that the eddy current occurs because of the relative's motion between the conductor and the magnetic field whereas the hysteresis loss occurs because of the reversal of the magnetism.

Difference between hysteresis and the eddy current loss :
  • The loss which occurs because of the eddy current is known as the eddy current loss. The eddy current induces because of the interaction of the variable magnetic field and conductor. So the losses which occur of the reversal of the magnetizing force is known as the hysteresis loss 
  • The eddy current loss occurs because of the interaction of the magnetic field and conductor. The hysteresis loss occurs because of the main reason is a reversal of the magnetism
  • The eddy current loss is minimised by using the thin core of lamination. The silicon steel material is used for minimising the hysteresis loss
