SimPEG.electromagnetics.frequency_domain.sources.CircularLoop.hPrimary#

CircularLoop.hPrimary(simulation)[source]#

Compute primary magnetic field.

Note that we compute analytic vector potential and take numerical curl so that B is divergence-free.

Parameters:
simulationBaseFDEMSimulation

A SimPEG FDEM simulation

Returns:
numpy.ndarray

Primary magnetic field
