A magnetic wire is bent at its midpoint at an angle of 60o. If the length of the wire is l and its magnetic moment is M then the magnetic moment of new shape of wire will be- |
2M M $\frac{M}{2}$ $\frac{M}{\sqrt 2}$ |
$\frac{M}{2}$ |
$ \text{Length of the wire become }lcos 60^o$ $ M = m lcos 60^o = \frac{ml}{2} = \frac{M}{2}$ |
