Two lines of force due to a bar magnet:

$A$ bar magnet of length $l$ and magnetic dipole moment $M$ is bent in the form of an arc as shown in the figure. The new magnetic dipole moment will be

State the direction of the magnetic dipole moment (from $S$ to $N$ pole of the magnet) and write the unit of the magnetic dipole moment.

$A$ magnetized wire of magnetic moment $M$ and length $l$ is bent in the form of a semicircle of radius $r$. Then its new magnetic moment is:

The distance between the poles of a horse shoe magnet is $0.1\, m$ and its pole strength is $0.01\, A\cdot m$. The induction of magnetic field at a point midway between the poles will be

$A$ bar magnet is cut into two equal parts. Then,which of the following quantities may change?
