Magnetic Moment of Point Charge

  1. Apr 17, 2013 #1
    Say I have a stationary point charge with a matching charge moving past it at a velocity. What is the magnetic potential energy of the stationary point charge? The formula for magnetic potential energy involves pole strength so I am confused. I can calculate the B field the stationary particle feels but to get the potential energy I need to dot product with the magnetic moment.

    How did you get on?

    You can work out the magnetic field due to the moving charge at the position of the point charge.
    But: does a stationary point electric charge feel a magnetic force?

    note: a classical point charge does not have a magnetic dipole moment.
