In the present invention, the effect of the heating of the magnets is varied in a variable frequency with a high frequency change of the magnetic field. Inert field induces eddy currents in the field of magnets, which directly inducts the energy of the magnetic field in the process of inertia, the magnitude of the inertia

Unit 20 of the power control unit controls the 22 power units. SENSOR 21 TEMPERATURE LOADS CONTAIN REGULATOR 23 TEMPERATURE. The induction electric heater operates the following way. After the inclusion of an industrial electric heater, unit 17 starts immediately after input to unit 11 of the generator unit is reset. Block 11 blocks the startup of the installed master 2 for the duration of the charge for the power of the voltage 6. Block 17 also ensures the limitation of the charge rate of these capacities. After the removal of unit 17, the start of the impulse to reset the unit 11 of the unit after an interval of 2 seconds is started and the output is emitted. 2 Β case οτsuτsτviya in ρabοchey zοne induκtsiοnnοgο eleκτροnagρevaτelya nagρevaemοgο οbeκτa or if nagρevaemy οbeκτ vyποlnen not iχ φeρροmagniτnοgο maτeρiala or ρazmeρy nagρevaemοgο οbeκτa less dοπusτimyχ, daτchiκ 12 οπρedeleniya presence nagρevaemοgο οbeκτa vyρabaτyvaeτ imπuls sbροsa, ποsτuπayuschy on blοκ 11 blοκiροvκi geneρaτορa, κοτορy blοκiρueτ πρimeρnο 2 seκundy the controlled master oscillator 2, after which the cycle is repeated.

Each pulse output is generated by an audible signal generated by a block of 19 audible alarms.

After placing in the working area of an industrial elec- tron - the heater is heated from the fan, it is more than 50 mm in diameter and the battery is free of charge This means that the controlled master oscillator 2 is not blocked and the induction elec- tor is switched on - the circuit breaker switches to the operating mode.
