Various Terms Related to Magnetism:
Magnetic Intensity(H):- The capacity of magnetic field to magnetize the substance is measured in terms of magnetic intensity of the field.
Intensity of Magnetisation(I):- The intensity of magnetization of a magnetized substance represent the degree to which the substances magnetized.
Magnetic Induction(B):- It is defined as the number of magnetic lines of induction crossing per unit area normally through the magnetic substance.
Magnetic induction B is the sum of the magnetic field B₀ and the magnetic field μ⁰I produced due to the magnetization of the substance.
Thus-
Magnetic Susceptibility:- It is the measure of how easily a substance is magnetized in the magnetising field. It is a ratio of the intensity of magnetisation to the magnetic intensity.
