A unipolar induction apparatus was fabricated for an experiment in which a metal conductor was rotated in a magnetic field applied by a pair of magnets, and the induced voltage between the outside of the metal conductor and the rotation axis was measured. A phenomenon was recognized whereby a voltage was induced when only the metal conductor were rotated, but was not fully induced when only the magnets was rotated. Similar experiments were performed for two polar magnets. An alternating trapezoid voltage and a direct voltage were respectively induced when all the parts were rotated together and when only the metal conductor was rotated. An induced alternating voltage with a nearly sinusoidal wave was observed when only the magnets were rotated. It seems likely that this phenomenon could be used in a new sensor for the
