PURPOSE: To directly provide power by making use of an external heat source with no electric power used.
CONSTITUTION: A heat supplying section 30 and a heat removing section 31 are disposed while being close to a rotor 10. Let a high temperature medium go through the heat supplying section 30, and let a low temperature medium go through the heat removing section 31. A magnetic fluid 25 around the heat supplying section 30 is then in a high temperature condition, and the magnetic fluid 25 around the heat removing section 31 is in a low temperature condition. A magnetic field is applied to the magnetic fluid 25 by a permanent magnet 11. There exists the difference in magnetization because of the difference in temperature between the magnetic fluid 25 in a high temperature condition and the magnetic fluid 25 in a low temperature condition. Force moving the magnetic fluid 25 from the low temperature side to the high temperature side is excerted, so that the rotor 10 is thereby rotated.
