This article considers the development of an information-measuring system for determining the thermophysical parameters of electrical devices. The developed functional diagram of the device is presented. Experimental studies were carried out in the COMSOL program. As a result of an experimental study of the transfer of heat from one part of the electromagnet to another, namely from the magnetizing coil, through the core to the environment, it was concluded that the best location of the temperature sensors is in the upper part of the body of the electromagnet EM-34-5. The data obtained can be used to determine the thermophysical parameters, in solving problems of the theory of inverse problems of heat transfer and heat transfer.
