SimPEG.electromagnetics.time_domain.sources.MagDipole.bInitial#

MagDipole.bInitial(simulation)[source]#

Compute initial magnetic flux density.

Note that we compute analytic vector potential and take numerical curl do it is divergence free on the mesh.

Parameters:
simulationBaseTDEMSimulation

A SimPEG TDEM simulation

Returns:
numpy.ndarray

Initial magnetic flux density
