$A$ bar magnet of magnetic moment $M$ is placed at right angles to a magnetic induction $B$. If a force $F$ is experienced by each pole of the magnet,the length of the magnet will be

Three identical bar magnets are riveted together at the centre in the same plane as shown in the figure. This system is placed at rest in a slowly varying magnetic field. It is found that the system of magnets does not show any motion. The north-south poles of one magnet are shown in the figure. Determine the poles of the remaining two.

The resultant magnetic moment of a neon atom will be

$A$ magnetic needle is kept in a non-uniform magnetic field. It experiences

What is the fundamental difference between an electric dipole and a magnetic dipole?

$A$ bar magnet of magnetic moment $3.0 \, A-m^2$ is placed in a uniform magnetic induction field of $2 \times 10^{-5} \, T$. If each pole of the magnet experiences a force of $6 \times 10^{-4} \, N$,the length of the magnet is.....$m$
