Show the magnetic field of bar magnet in a panoramic way.
The distance between the poles of a horse shoe magnet is $0.1\, m$ and its pole strength is $0.01\, amp-m$. The induction of magnetic field at a point midway between the poles will be
A long magnetic needle of length $2\,L$, magnetic moment $ M$ and pole strength $m$ units is broken into two pieces at the middle. The magnetic moment and pole strength of each piece will be
The unit of magnetic moment is
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
