class simpeg.electromagnetics.natural_source.Simulation1DMagneticField(mesh, **kwargs)

Bases: BaseFDEMSimulation

1D finite volume simulation for the natural source electromagnetic problem.

This corresponds to the TM mode 2D simulation where the magnetic field is located at faces (nodes) and the electric field is on edges (cell_centers).
