biot_savart_single(currents: Array, positions: Array, delta_line_segments: Array, query_point: Array)

Biot-Savart law for multiple line elements and a single query point

Parameters:

• currents (Array) – Currents in the coil segments [N,]

• positions (Array) – Positions of the line elements [N, 3]

• delta_line_segments (Array) – Line element vectors [N, 3]

• query_point (Array) – Point at which to evaluate the field [3,]

Returns:

Magnetic field at the query point [3,]

Return type:

jnp.ndarray
