A device for positioning a workpiece includes a socket body rotatably held on a metallic ball by an array of permanent magnets arranged into a partial socket. An air delivery system controls a flow of air passing between the magnets and the ball to alter the friction between the socket body and the ball. A positive flow of air into the socket reduces the friction, allowing the workpiece to be more easily rotated during repositioning, whereas drawing air away from the socket produces a partial vacuum which increases the friction, causing the socket body to be locked in a single position on the ball.
