Board D. Smith miniature
In these experiments, the author presents a prototype Board don Smith in miniature. This applies to a ferrite rod wound with copper wire 1.5 sq. mm and a pulse generator with adjustable duty cycle. In certain settings and there is this effect.
The following video shows the experiment layout and the indications of the oscilloscope.
Further, the author has around the emitter coil of copper bars in which there are relatively large currents that can be seen when connecting to it a powerful incandescent lamp. In this case, the side effect is fully preserved.
In these experiments, the power consumption from the power source is of the order of 30 watts and almost does not change with load.
