1. A handle assembly, comprising:
a rotatable handle;
a first magnet coupled to a structure; and
a second magnet coupled to the rotatable handle such that, in response to rotation of the rotatable handle from a home position, the second magnet is operable to move toward or away from the first magnet; and
wherein the first magnet and the second magnet generate magnetic forces that interact to generate a return torque in response to rotation of the rotatable handle from the home position.
