1. The problem statement, all variables and given/known data Here we have two electrons rotating around z axis with angular speed w in a circle of radius R. They are on the same straight line (have difference in phase π). Find the magnetic moment. 2. Relevant equations Magn. moment m=(1/2c)*∫dV [ r j ] 3. The attempt at a solution Current J=dq/dt=qw/π; m=(qw/2cπ)*∫dr∫dφ r*r*δ(r-R)=qwR2/c Am I right?
