4. Consider two magnetic dipoles: m = m, at the origin and m2 = m, at 7 = re. (a) Sketch or plot the magnetic field of my in the az-plane. (b) By thinking of me as a small loop of current, argue whether the magnetic force on m due to my should be attractive or repulsive. (c) Calculate the force between the two dipoles. 4.
