1. A method, comprising:
positioning a ball lens in a holder, wherein the ball lens is a Faraday rotator; and
vibrating the holder or applying aerodynamic levitation to the ball lens while generating a magnetic field in a desired direction of an optic axis of the ball lens so that the ball lens rotates until the optic axis is in the desired direction.
