Problem

Three planar wire loops, all lying flat and each carrying a steady current

I = 2.0\,\mathrm{A}

, enclose the same area

A = 0.050\,\mathrm{m^2}

: one is a square, one is an equilateral triangle, one is a circle. ((a)) Find the magnitude of the magnetic moment of the square loop. ((b)) Find the magnitude of the magnetic moment of the triangular loop. ((c)) Find the magnitude of the magnetic moment of the circular loop.
