BaseMagneticDipole.distance(xyz)#

Scalar distance from dipole to a set of gridded xyz locations

Where $\mathbf{p}$ is the location of the source and $\mathbf{q}$ is a point in 3D space, this method returns the scalar distance:

$$d=\sqrt{(q_x-p_x{)}^2+(q_y-p_y{)}^2+(q_z-p_z{)}^2}$$

for all locations $\mathbf{q}$ supplied in the input argument xyz. For dipoles, $\mathbf{p}$ is the dipole location. For circular loops, $\mathbf{p}$ defines the center location for the loop.

Parameters:

xyz(n, 3) numpy.ndarray

Gridded xyz locations

Returns:

14. numpy.ndarray Scalar distances from dipole to xyz locations
