Abstract
An apparatus comprises a first magnetic plate; a second magnetic plate oriented parallel no the first magnetic plate, magnetically coupled to the first magnetic plate, and slidable relative to the first magnetic plate; a dielectric material positioned between the first magnetic plate and the second magnetic plate; and a contact in communication with the first magnetic plate and the second magnetic plate through which a voltage is applied, the voltage generating a signal that is responsive to a task performed on a mobile device, the signal providing a haptic effect to the first magnetic plate and the second magnetic plate upon sliding of the first magnetic plate relative to the second magnetic plate.
