Question

(vii) The dimensions of magnetic dipole moment are (a) [L2 I] (b) [LI] (c) [L-1 1] (d) [L-2 1).​

Answer 1

Magnetic dipole moment

It is defined as the product of the current and the area through which the current passes.

$\huge{\boxed{\sf{M=A \ I}}}$

Where,

• M = magnetic dipole moment

• A = area

• I = current

Dimensions:

• $\sf{Area=L\times L = [L^2]}$

• $\sf{Current =[I]}$

Applying the dimensions in the expression:

$\sf{\implies M=[L^2 \ I]}$

$\huge{\boxed{\sf{ Dimension =[L^2 \ I]}}}$

Answer is option (a).
