SimPEG.electromagnetics.frequency_domain.sources.CircularLoop

class SimPEG.electromagnetics.frequency_domain.sources.CircularLoop(receiver_list, frequency, location=None, orientation='z', radius=1.0, current=1.0, n_turns=1, mu=1.25663706212e-06, **kwargs)

Bases: SimPEG.electromagnetics.frequency_domain.sources.MagDipole

Circular loop magnetic source calculated by taking the curl of a magnetic vector potential. By taking the discrete curl, we ensure that the magnetic flux density is divergence free (no magnetic monopoles!).

This approach uses a primary-secondary in frequency in the same fashion as the MagDipole.
