Low grade heat is a byproduct of many man-made and natural processes. Recently, there has been advancement in the development of new devices and materials that can harness such low-grade heat. Thermomagnetic materials exhibit significant changes in magnetization following a small change in temperature around its Curie temperature. This physical property of the material can be harnessed in a device to convert thermal energy into other useful forms of energy like mechanical work. The thesis activity is carried out at the Singapore Institute of Manufacturing Technology, a research institute of A*STAR Singapore. The aim of the research is to improve the performance of a rotating thermomagnetic motor composed of thermomagnetic material.
