Two wires of the same length are shaped into a square and a circle. If they carry same current, ratio of the magnetic moment is

Two wires of the same length are shaped into a square of side 'a' and a circle with radius 'r'. If they carry same current, the ratio of their magnetic moment is

There are two wires of same length and they are shaped as square and circle. Same current flows through them. If ratio of magnetic moment of square to that with circle is found to be pi/n . What is the value of n?

A thin circular wire carrying a current I has a magnetic moment M. The shape of the wire is changed to a square and it carries the same current. It will have a magnetic moment
