Abstract

Faraday's unipolar induction was reexamined because of a question arised. An induced voltage between an outside of conductor and an axis of rotation was measured in a magnetic field applied by a pair of thin cylindrical magnets. Faraday's unipolar induction itself was made sure by that. But, it was made clear that when only a condutor rotated the voltage was induced, and on the other hand, when only magnets rotated it was not induced. These results are very strange phenomena from the electromagnetic point of view. From the above fact, we were interested in Faraday's life again. The more we knew his personality, the more we were struck with admiration. Faraday made his electrical motor one near after Oersted first discovered a magnetic effect induced by current. And ten years later, Faraday presented the electromagnetic induction and then discovered the unipolar induction. It seems indeed to be the Faraday who had to discover this phenomenon. It must be highly evaluated that Faraday had free conceptions. Since Faraday had little formal education, he could create new wonderful discoveries and abundant ideas from many simple experiments.
