Answer :

A. Electric dipole moment is the amount of polarity of an electric dipole which consists of 2 charges of equal magnitude but opposite polarities separated by a small distance.

Electric dipole moment is given by

Electric dipole moment(p) = magnitude of charge(q) × distance (d)

Dimensions of q = [TA]

Dimensions of d = [L]

Dimensions of p = [TA] × [L] = [TAL]

B. Magnetic dipole moment is defined as the strength of a magnetic object in a magnetic field.

Magnetic dipole moment is given as

Magnetic dipole moment (M) = current (I) × area (A)

Dimensions of I = [A]

Dimensions of A = [L2]

Dimensions of M = [L2] × [A] = [L2A]
