Abstract
A user input device that includes a rotary input control is described herein. The rotary input control includes first and second ferritic substrates; first and second permanent magnets extending between the first and second ferritic substrates to form a magnetic circuit; one or more magnetizing coils wrapped around the first permanent magnet; and a wheel defining a central volume within which the first and second ferritic substrates, the first and second permanent magnets and the one or more magnetizing coils are positioned. The user input device also includes a control system configured to direct current to the one or more magnetization coils to change a magnetization of the first permanent magnet to adjust a resistance profile of the rotary input control.
