Question

A uniform conducting wire of length 12a and resistance 'R' is wound up as a current carrying coil in the shape of ,

(i) an equilateral tringle of side 'a'

(ii) A square of side 'a'

The magnetic dipole moments of the coil in each case respectively are :

4Ia² and 3Ia²

$\sqrt 3 $ Ia² and 3I a²

3Ia² and Ia²

3Ia² and 4Ia²
