Question

Why angular momentum associated with a revolving electron is opposite in direction to its magnetic moment?

Answer 1

Dear Student, If the right hand fingers curl in the direction of particle motion, the thumb represents the direction of angular momentum. Same way if the right hand fingers curl in the direction of current, the direction along which thumb points represents the direction of magnetic moment. Since, electron is negatively charged current direction is opposite to that of the flow of current. That's why angular momentum associated with a revolving electron is opposite in direction to its magnetic moment. Regards
