MAGNETISM

A group of phenomena associated with magnetic field. Whenever an electric current flows, a magnetic field is produced; as the orbital motion and the spin of atomic elections are equivalent to tiny current loops, individual atoms create magnetic fields around them, when their orbital electrons have a net. Magnetic moment as a result of their angular momentum. The magnetic moment of an atom is the vector sum of the magnetic moments of the orbital motions and the spins of all the electrons in the atom. The macroscopic properties of a substance arise from the magnetic moments of it's components atoms and molecules. Different materials have different characteristics in an applied magnetic field; there are four main types of magnetic behavior, which are:

1. Diamagnetism

2. Paramagnetism

3. Ferromagnetism

4. Antiferromagnetism￼￼
