Question

What is the Intensity Of Magnetisation

Answer 1

Explanation:

It represents the extent to which a specimen is magnetised when placed in a magnetising field.

Or in other words the intensity of magnetisation of a magnetic material is defined as the magnetic moment per unit volume of the material.

M = Magnetic moment/volume = μM / V …1

Let a = Uniform area of cross-section of the magnetised specimen.

l = magnetic length of the specimen.

m = strength of each pole of the specimen,

As μm = ml

and V = al

then equation (1) becomes

M = m x 2l / a x 2l

or M = m/a

thus intensity of magnetisation of a magnetic material is also defined as the pole strength per unit area of cross-section of the material.

Unit : M= magnetic moment / Volume

M= Amp.metre2 / metre3 = Am -1

Answer 2

intensity of magnetization is denoted by the letter I. it represents the extent to which the material is magnetised. when we place a material in the magnetic field, atomic dipoles of the material tense to align Fully or partially in the direction of the field.
