simpeg.potential_fields.magnetics.UniformBackgroundField#

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

A constant uniform background magnetic field.

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

Parameters:

receiver_listsimpeg.potential_fields.magnetics.Point, list of simpeg.potential_fields.magnetics.Point or None: Point magnetic receivers.
amplitudefloat: Amplitude of the inducing background field, usually this is in units of nT.
inclinationfloat: Dip angle in degrees from the horizon, positive value into the earth.
declinationfloat: Azimuthal angle in degrees from north, positive clockwise.
