FIELD: physics. ^ SUBSTANCE: invention is related to the field of demonstration properties in the area of physics and is intended for demonstration of heat conductivity process in ferromagnetics installed in magnetic field. The result is achieved due to the fact that according to invention, device for visualisation of ferromagnetic heat conductivity consists of ferromagnetic under investigation, arranged in the form of movable ring, L section of which is installed into clearance of magnetic field, on one side of which ferromagnetic is heated up to temperature T2 by electric heating element connected via stepdown transformer with voltage-controller source of AC, and on the other side - it is cooled down to temperature T1<T2. It is arranged to use diffuser with compressor to cool ferromagnetic by air flow. Invention makes it possible to produce additional information on properties of ferromagnetics and is of certain scientific interest for experimenter physicists that develop ferromagnetics. ^ EFFECT: provision of thermal field movement speed visualisation. ^ 5 dwg |
