Ball channel

Abstract

A non-magnetic ball housing can include an enclosed end and an open end. A plurality of non-magnetic ball bearings can be positioned within the enclosed end of the non-magnetic housing. A ball magnet can be adjacent to the plurality of non-magnetic ball bearings. A non-magnetic restraining plate can be coupled to the open end of the non-magnetic housing to secure the ball magnet within the non-magnetic ball housing while allowing the ball magnet to freely rotate within the non-magnetic ball housing. The non-magnetic restraining plate can include a restraining plate opening such that at least a portion of the ball magnet protrudes out of the restraining plate opening. A diameter of the restraining plate opening can be less than a diameter of the ball magnet. A metal channel can be magnetically coupled to at least a portion of the ball magnet protruding out of the restraining plate opening.
