Discuss magnetic dipole moment. What is its effect on atom and on molecules? Explain.

A magnetic dipole moment is a measure of the strength of a magnetic dipole (a tiny current loop or a spinning charged particle). It is defined as the product of the current flowing in a loop and the area enclosed by that loop. $$\vec{\mu} = I \cdot \vec{A}$$ where: - $I$ = current in the loop -
