Question

A bar magnet is cut into two equal halves by a
plane parallel to the magnetic axis. Of the
following physical quantities the one which remains unchanged is
(a) pole strength
(b) magnetic moment
(c) intensity of magnetisation
(d) moment of inertia

Answer 1

Answer:

Intensity of magnetization is a property which depends on the nature of the material whereas pole strength, magnetic moment and moment of inertia depend on the dimensions of the body.

Cutting along the axial line changes pole strength by m/2 and area as well to A/2 and magnetization remains same.

Because of this reason the correct answer would be option (c).

Explanation:

Hope this helps you anna.

Answer 2

Answer:

$intensity \: of \: magnetisation$
