Magnetic dipole moment of a revolving electron In hydrogen- like atoms, an election revolves around the nucleus. It's motion is equivalent to a current loop which possesses a magnetic dipole moment = IA. Consider an electron revolving anticlockwise around a nuclues in an orbit of radius r with speed v and time period T.         Equivalent current,           I = charge/time = e/T = e/2πr/v = ev/2πr         Area of the current loop,            A = πr × r The orbital magnetic moment of the electron is                 Magnetic moment = IA = ev. πr × r/2πr             Magnetic moment = evr/2        ...... (1)         According to right hand thumb rule, the direction of the magnetic dipole moment of the revolving electron will be...
