Question

What is difference between bound and polarization current

Answer 1

Answer:

Physically, the bound currents on the surface of a magnetized material (and also in its. volume for a non-uniform M) originate from the mis-cancellation of the microscopic currents. inside the atoms which give rise to their magnetic moments.

Polarization occurs when an electric field distorts the negative cloud of electrons around positive atomic nuclei in a direction opposite the field. This slight separation of charge makes one side of the atom somewhat positive and the opposite side somewhat negative.
