Question

A bar magnet is cut into two equal halves by a plane parallel to the magnetic axis. The following physical quantities, the one which remains unchanged is, Pole strengths, Magnetic moment, Intensity of magnetization, Moment of inertia

MARKS App · Accepted Answer

For each half pole strength m becomes half M = m × 2 l becomes half and volume V = a × 2 l also becomes half therefore, magnetic intensity remains constant.
