Write the expression for the magnetic moment due to an electron circulating around the nucleus of an atom.

Text Solution

Verified by Experts

Magnetic moment `=Ipir^(2)=(evR)/2`. The direction of this magnetic moment is into the sheet of paper for clockwise current (due to anticlockwise motion of electron).
