class desc.magnetic_fields.biot_savart(eval_pts, coil_pts, current)Source

Biot-Savart law following [1].

Parameters:

• eval_pts (array-like shape(n,3)) – evaluation points in cartesian coordinates

• coil_pts (array-like shape(m,3)) – points in cartesian space defining coil, should be closed curve

• current (float) – current through the coil

Returns:

• B (ndarray, shape(n,3)) – magnetic field in cartesian components at specified points
