A suitable working example of this invention is a motor provided with a rotor having a magnet and a stator having a magnetic circuit which can be opened and closed or a motor provided with a rotor having a magnetic circuit which can be opened and closed and a stator having a magnet. The magnetic circuit is configured to be opened and closed with rotation of the rotor. When the magnet and the magnetic circuit of the rotor and the stator are in proximity to each other, the magnetic pole of the magnet of the rotor or the stator and that of the magnet of the magnetic circuit are arranged to face each other. Thus, the motor which can continuously rotate for a long time with a small energy is provided. |
