Thermo-magnetic motor

From Wikipedia, the free encyclopedia
Jump to: navigation, search

Thermo-magnetic motors convert heat into mechanical work by heating a ferromagnetic material above its Curie point (where it becomes non-magnetic) and then cooling it below that critical temperature. Experiments have only produced extremely inefficient working prototypes. [1] The thermo-magnetic motor principle has been studied as a possible actuator in so-called "smart" materials. [2]
