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

Attributes

N

n_turns.N has been deprecated.

current

Source current

moment

Dipole moment of the loop.

n_turns

Number of turns in the loop.

radius

Loop radius
