Question
A steel wire of length $l$ has a magnetic moment $M$. It is bent at its middle point at an angle of $60^{\circ} .$ Then the magnetie moment of new shape of wire will be(a) $M / \sqrt{2}$(b] $M / 2$(c) $M$(d) $\sqrt{2} M$
Step 1
The magnetic moment $M$ is given by $M = m \cdot l$, where $m$ is the magnetic strength. Show more…
