SimPEG.electromagnetics.frequency_domain.sources.CircularLoop.bPrimary#

CircularLoop.bPrimary(simulation)[source]#

Compute primary magnetic flux density.

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

Parameters
simulationBaseFDEMSimulation

A SimPEG FDEM simulation

Returns
numpy.ndarray

Primary magnetic flux density
