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?

Two wires of same length are made into a circle and square respectively. Currents are passed in then such that their magnetic moments are equal. Then the ratio of the magnetic field at their respective centres (circle:square) is
