An electromagnetic device is provided. It includes a plurality of input magnetic field generating devices, which will induce magnetic fields in output current generating devices. In one construction, the electromagnetic device can be operably coupled to a work input device wherein the electromagnetic device can be used as a generator set in combination with the energy input device. The input and output magnetic devices are arranged in radial arrays about a work input shaft. The output magnetic devices each include a core and a respective coil with the cores each having a longitudinal axis generally parallel to the axis of rotation of the shaft. The input devices and the output devices are mounted in respective carriers with the output device carrier being movable relative to the input device carrier.
