A uniform conduct

Answer :

Length of the wire is 12a.

Area of equilateral triangle is

Number of loops made is n=12a/3a = 4

So, magnetic moment is m=niA

Area of equilateral square is

Number of loops made is n=12a/4a = 3

So, magnetic moment is m=niA

Area of hexagon is

Number of loops made is n=12a/6a = 2

So, magnetic moment is m=niA
