Abstract
A drive device includes: a magnet; a coil and a position sensor each of which receives an action from the magnet; a first electrical wiring line that passes through the position sensor and causes first electromotive force to occur by causing an electric current to flow in the coil; a second electrical wiring line that causes second electromotive force, which is electromotive force in an opposite direction to the first electromotive force, to occur by causing the electric current to flow in the coil; and a processor configured to control the electric current flowing in the coil based on an output of the position sensor.
