1. An apparatus, comprising:
a shaft configured to rotate about a first axis and a second axis, the shaft having a first end and a second end opposite the first end;
a first magnet configured to emit a controllable magnetic field; and
a second magnet interposed between the first magnet and the first end of the shaft, wherein the second magnet is configured to provide a force on the first end of the shaft such that the second magnet resists rotation of the shaft about at least one of the first or second axes while the first magnet emits the controllable magnetic field.
