A uniform conducting wire of length \(12\,a\) and resistance 'R' is wound up as a current carrying coil in the shape of,
(i) an equilateral triangle of side 'a'.
(ii) a square of side 'a'.
The magnetic dipole moments of the coil in each case respectively are
(i) an equilateral triangle of side 'a'.
