class geoana.em.BaseMagneticDipole(moment=1.0, **kwargs)

Base class for magnetic dipoles.

The BaseMagneticDipole class defines the basic properties for magnetic dipoles. Where \(d\mathbf{m}\) defines the dipole moment, the magnetic dipole is defined as:

\[\mathbf{s_m}(\mathbf{r}) = \mathbf{m} \, \delta(|\mathbf{r} - \mathbf{r_s}|)\]

where \(\mathbf{r_s}\) is the location of the source. For more, visit EM GeoSci .

Parameters:

momentfloat, optional

Amplitude of the dipole moment for the magnetic dipole (\(A/m^2\)). Default is 1 \(A/m^2\).

Attributes

location	Location of the dipole
moment	Amplitude of the dipole moment of the magnetic dipole (\(A/m^2\))
orientation	Orientation of the dipole as a normalized vector

Methods

cross_orientation(xyz)	Cross products between a gridded set of vectors and the orientation of the source.
distance(xyz)	Scalar distance from dipole to a set of gridded xyz locations
dot_orientation(vecs)	Dot product between the orientation of the source and a gridded set of vectors.
vector_distance(xyz)	Vector distance to a set of gridded xyz locations.
