The magnetic moment of a circular coil ...

The magnetic moment of a circular coil carrying current is

A

`vec(M) = 2I vec(A)`

B

`vec(M) = (I vec(A))/(2)`

C

`vec(M) = I vec(A)`

D

`vec(M) = (vec(A))/(2I)`

Text Solution

Verified by Experts

The correct Answer is:
C

Vector `vec(A)` is perpendicular to the surface, magnetic moment `vec(M)` will also be perpendicular to the plane of circular coil.
