Abstract
The operating principle of a thermomagnetic motor is due to the magnetic phase transition (ferro paramagnetic) of magnetic materials around their transition, or Curie, temperature. The main components of a thermomagnetic motor are the magnetic material and the magnetic circuit. If the magnetic material presents the Curie temperature around the room temperature, it may have potential to be applied in thermomagnetic motors. Today are known several first and second order transition magnetic materials with Curie temperature of 20oC and above. These materials also present large magnetocaloric effect. The magnetic circuit is responsible to guarantee a high magnetic field region which magnetically interacts with the magnetic material. This way, the main objective of the present research is to design a thermomagnetic motor to test different magnetic materials. However, we first introduce in this paper the design and assembly procedure of a magnetic circuit, currently under construction at State University of Maringá.
