Determine the dimensions of magnetic dipole moment

M

. The defining equation is

M = IA

, where

A

is area and

I

is current.

Options

A $LTI$
B $L^2TI$
C $L^2I$
D $LI$

Correct answer

C. $L^2I$

Step-by-step solution

The defining equation for magnetic dipole moment is

M = IA

.

The dimensional formula for current

I

is

[I]

.

The dimensional formula for area

A

is

[L^2]

.

Substituting these dimensions into the equation, we get:

[M] = [I] \times [L^2] = [L^2I]
