pyoculus.toybox.cylindrical_toybox.A_circularcurrentloop(rr: array, R: float, Z: float) → Array

Contravariant component of the vector potential \(A\) for the circular current loop perturbation.

Parameters:

• rr (array) – Position vector in cylindrical coordinates.

• R (float) – R coordinate of the center of the circular current loop.

• Z (float) – Z coordinate of the center of the circular current loop.

Returns:

\(A\) field at position rr.

Return type:

array
