The damping effect of Eddy Currents is used in some moving coil galvanometers to make them dead-beat. The coil of such galvanometres is wound on a light metal frame. ... The oscillations of moving coil ballistic Galvanometer are stopped by short circuiting the coil, this being due to the induced current in the coil itself.
