In one embodiment stationary magnets are mounted adjacent the paths of travel of ferrite rods which carry electrical windings. In another embodiment a hollow torus carrying an electrical winding is mounted concentric of the axis of rotation of the roll and has a freely-falling magnet therein. In another embodiment the torus is replaced by a plurality of hollow elongate carriers each carrying a winding and each having a freely-falling magnet therein. | |
