In this paper Thermodynamic performance analysis for a magneto caloric material such as Gadolinium and Terbium is presented. Performance parameter is taken as magnetic entropy change and temperature change at constant room temperature, different magnetic fields. Furthermore the thermodynamic performance is compare between gadolinium and Terbium. Also, a study on the development of magnetic refrigerator at room temperature has been also carried out a model of Rotating Magnetic refrigeration has been developed. By use of MCE it is possible to create magnetic refrigerators—the machines where magnetic materials are used as working bodies instead of a gas, and magnetization/demagnetization is used instead of compression/expansion in conventional refrigerators. To realize any cooling process, it is necessary to have a system in which entropy depends on temperature and some external parameter. In the case of a gas this parameter is pressure, and in the case of a magnetic material it is magnetic field.
