The magnetic moment has dimensions of

Options

A. `[LA]`
B. `[L^(2)LA]`
C. `[LT^(-1)A]`
D. `[L^(3)T^(-1)A]`

Answer

b

Explanation

The magnetic moment of a current carriying loop is define as the product of current in the loop with the area of loop in vector from , `vec M = 1 vec A`
Thus dimesion of `[M] = [A] [L^(2)] = [L^(2)A] `
