class SimPEG.electromagnetics.time_domain.sources.LineCurrent(receiver_list=None, location=None, current=1.0, mu=1.25663706212e-06, srcType=None, **kwargs)[source]#

Bases: SimPEG.electromagnetics.time_domain.sources.BaseTDEMSrc

Line current source.

Given the wire path provided by the (n_loc, 3) locations array, the cells intersected by the wire path are identified and integrated source terms are computed.

Parameters
receiver_listlist of SimPEG.electromagnetics.time_domain.receivers.BaseRx

List of TDEM receivers

location(n, 3) numpy.ndarray

Array defining the node locations for the wire path. For inductive sources, you must close the loop, (i.e. provide the same point as the first and last entry of the array).

currentfloat, optional

A non-zero current value.

mufloat, optional

Magnetic permeability to use.

Attributes

current

Source current

location

Line current nodes locations

n_segments

The number of line current segments.
