Define Two-Dipole Interaction?
Two classical dipoles with dipole moments μ1 and μ2 are separated by a distance R so that only the orientation of the magnetic moments is free. They are inside thermal equilibrium at a temperature T. Compute the mean force between the dipoles for the high-temperature limit μ1μ2/TR3<<1.Hint The potential energy of interaction of two dipoles is
