A wire of length I is bent to form a circular, form of radius R. If I be the current through the loop then what will be its magnetic moment?

A copper wire of diameter 0.04 in. and length 50 cm is bent in the form of a circular loop. The plane of the loop is normal to a uniform magnetic field which is increasing with time at a constant rate of 100 G s^(-1) . What is the rate of joule heating in the loop? [Resistivity of copper =1.7xx10^(-8)Omega.m, 1" in."=2.54cm ]
