Two wires of same length are shaped into a square and a circle. If they carry same current, ratio of the 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 coil of 'N turns and radius 'R' carries a current I. It is unwound and rewound to make a square coil of side 'n'having same number of turns 'N'. Keeping the current I same, find the ratio of the magnetic moments of the square coil and the circular coil.

A square loop is carrying a steady current I and the magnitude of its magnetic dipole moment is m.If this square loop is changed to a circular loop and it carries the same current the magnitude of the magnetic dipole moment of circular loop will be
