Abstract

The invention relates to an electromagnetic device (4) including two magnetically coupled coils (8, 10) capable of driving a movable element (6) in a first mode of operation and of converting voltage in a second mode of operation. In said device, each coil (8, 10) has a structure comprising multiple conductors that are insulated from each other so as to reduce the skin effect on the coils (8, 10).
