Atoms can be trapped using a combination of static and rotating magnetic fields. A theoretical analysis is performed of a rotating polarisation axis which is used to eliminate regions of zero coupling. A similar result is found using linear polarisation, but in the case of circular polarisation no orientational dependence in the coupling remains when on resonance.
