Moving charges and magnetism (part-1)

To describes how an electric field affects and is affected by a medium , we can use Electric permittivity. It is determined by the ability of a material to polarise in response to an applied field, and thereby to cancel, partially, the field inside the material.

To describes how an electric field affects and is affected by a medium , we can use Electric permittivity. It is determined by the ability of a material to polarise in response to an applied field, and thereby to cancel, partially, the field inside the material. Similarly, magnetic permeability is the ability of a substance to acquire magnetisation in magnetic fields. It is a measure of the extent to which magnetic field can penetrate matter.
