Abstract

The invention discloses a heat-power conversion magnetism device. The heat-power conversion magnetism device includes a magneto caloric effect material so that the magnetic field thereof can be changed according to the temperature difference. The heat-power conversion magnetism device rotates by changing the magnetic field of the magneto caloric effect material.
