Homework #12a
Continue the multipole expansion for the scalar and vector potentials to determine the magnetic dipole contribution
to Electric and Magnetic fields in the radiation zone from an arbitary current loop.
Compare your results with Griffiths for the special case of the magnetic dipole alligned with the z-axis and oscillating harmonically in time (his equations 11.36 and 11.37).
