Chapter-6 : Magnetic Fields in Matter

Chapter-6 : Magnetic Fields in Matter. Magnetization Dia-magnets, Paramagnets, Ferro-magnets At microscopic level, electrons in atom revolve around the nucleus as well have spin. This will form tiny current loop and hence dipole moment.

Magnetization

Magnetization. Paramagnetism Paramagnetic materials present a magnetization that is proportional to the applied field and reinforces it. This arises from the existence of magnetic dipoles in the material. Diamagnetism
