The spontaneous generation of an electric current was examined by means of a camphor boat. The camphor boat attached a small magnet was spontaneously circled around a coil in a petri dish, resulting in the generation of an induced electric current. Moving modes of the camphor boat were determined by the shape of the petri dish and the camphor boat. The angular velocity of the camphor boat was about pi/sec. The influences of the distance from the coil to the magnet and of the angular velocity on the generated electricity were also examined.
