class simpeg.potential_fields.magnetics.UniformBackgroundField(receiver_list, amplitude, inclination, declination)[source]#

Bases: BaseSrc

A constant uniform background magnetic field.

This inducing field has a uniform magnetic background field defined by an amplitude, inclination, and declination.

Parameters:
