Thermal magnetic engine and thermal magnetic engine system

A thermal magnetic engine, comprising:

• a fixed element;
• a rotation element comprising a working material, the rotation element rotating relative to the fixed element;
• a first working fluid flowing through the rotation element, forming a temperature difference on the working material;
• and
• a fin structure disposed on the rotation element,
• wherein the rotation element rotates along a rotating direction due to the temperature difference on the working material and due to the flowing of the first working fluid through the fin structure,
• wherein the fixed element comprises a magnetic unit, the magnetic unit is disposed on the fixed element and configured for establishing a magnetic field, and magnetic flux of the magnetic field passes through the working material of the rotation element, the working material makes the rotation element rotate along the rotating direction due to the temperature difference of the working material under the magnetic field,
• wherein the rotation element comprises a rotation frame and a rotation shaft, the fin structure comprises a plurality of fins, the fins are extended from at least one side of the surface of the rotation frame, and the fins are disposed to be substantially ninety degrees from a direction of a flow path where the working fluid flows through the rotation element.
