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

$A$ wire of magnetic material of length $2L$ and magnetic moment $M$ is bent at the centre to form an $L$-shaped wire. Its magnetic moment is

$A$ 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.....$m$

$A$ magnetic rod of length $L$ has a magnetic dipole moment $M$. If it is bent into a semicircle,what will be its new magnetic dipole moment?

The magnetic moment of the arrangement shown in the figure is ............. $M$.

$A$ magnetized steel wire of length $L$ has a magnetic moment $M$. It is then bent into a semicircular arc. The new magnetic moment is:
