SimPEG.electromagnetics.time_domain.sources.CircularLoop#

class SimPEG.electromagnetics.time_domain.sources.CircularLoop(receiver_list=None, location=None, orientation='z', radius=1.0, current=1.0, n_turns=1, mu=1.25663706212e-06, srcType='inductive', **kwargs)[source]#

Bases: 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!).

Parameters:

receiver_listlist of SimPEG.electromagnetics.time_domain.receivers.BaseRx: A list of TDEM receivers
location(dim) np.ndarray, default = np.r_[0., 0., 0.]: Source location.
orientation{‘z’, ‘x’, ‘y’} or (3) numpy.ndarray: Loop orientation.
radiusfloat, default = 1.: Loop radius
currentfloat, default = 1.: Source current
mufloat: Background magnetic permeability
srcType{‘inductive’, “galvanic”}: ‘inductive’ to implement as inductive source and ‘galvanic’ to implement as galvanic source
Nint, default = 1: Number of turns in the loop
