(C) The magnetic dipole moment $(M)$ is defined as the product of the pole strength $(m)$ and the magnetic length $(2l)$ of the dipole,i.e.,$M = m 	imes 2l$.This property is an intrinsic characteristic of the magnet itself.It does not depend on the position or the distance of the point where the magnetic field is being measured.Therefore,changing the distance between the point and the magnet does not affect the magnetic dipole moment.Thus,the magnitude of the dipole moment remains $X$.

The magnetic dipole moment of a short magnetic dipole at a distant point along the equator of the magnet has a magnitude of $X$ in $SI$ units. If the distance between the point and the magnet is halved,then the magnitude of the dipole moment will be
