Vedclass · Answer

(A) The magnetic moment $M$ of a bar magnet is given by $M = m 	imes L$,where $m$ is the pole strength and $L$ is the magnetic length of the magnet.When a magnet is placed in a magnetic field $B$,the force experienced by each pole is given by $F = mB$.From this,the pole strength is $m = F/B$.Substituting the value of $m$ into the magnetic moment equation: $M = (F/B) 	imes L$.Rearranging for the length $L$,we get: $L = MB/F$.

$A$ 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
