摘　　要：简述了涡电流加热的实验原理,并设计了涡电流加热实验仪.该实验仪利用给带铁芯的线圈通电产生的磁场,通过磁场变化产生涡电流,同时释放出热量达到涡电流加热的目的.比较了几种金属的涡电流加热与同种金属在不同电源频率下的涡电流加热的效果.The experiment theory and the structure of heating apparatus using eddy current are introduced. Changing the current in coil to produce magnetic field, the apparatus uses the changing magnetic field to produce eddy current and produce heat. The heating effects of eddy current in different＂ metals and the same metal with different frequency of power supply are studied respectively.
