Magnetic moment of a current carrying coil is defined as the product of current in the coil with the area of coil in vector form. That is, vecM=I vecA Thus, dimensions of M =[ A ][ L 2] =[ L 2 A ]

Q. The magnetic moment has dimensions of

$[L A]$

$[L^{2} A]$

$[L T^{- 1} A]$

$[L^{2} T^{- 1} A]$

Magnetic moment of a current carrying coil is defined as the product of current in the coil with the area of coil in vector form.
That is, $M = I A$
Thus, dimensions of $M = [A] [L^{2}]$
$= [L^{2} A]$

Q. The magnetic moment has dimensions of

[LA]

[L2A]

[LT−1A]

[L2T−1A]

Magnetic moment of a current carrying coil is defined as the product of current in the coil with the area of coil in vector form. That is, M=IA Thus, dimensions of M=[A][L2] =[L2A]

$[L A]$

$[L^{2} A]$

$[L T^{- 1} A]$

$[L^{2} T^{- 1} A]$

Magnetic moment of a current carrying coil is defined as the product of current in the coil with the area of coil in vector form.
That is, $M = I A$
Thus, dimensions of $M = [A] [L^{2}]$
$= [L^{2} A]$
