Abstract – Rotating magnetic field is a field whose direction rotates in space and the first one who noticed and demonstrated it was Nikola Tesla with his experiment (invention) so called «Tesla's Egg». In that experiment a metal egg was lifted up vertically while rotating around its axis under influence of rotating a.c. magnetic field.

 

In this paper, electronic version of «Tesla's egg experiment» using low level D.C. power supply will be described. To enable electronic performance of «Electronic Tesla's egg» it is necessary to accomplish more than one task; one needs to gain signals of specified frequency that are phase shifted, and to amplify signals so that the electrical pulse current in a set of spatially arranged coils can generate a magnetic field strong enough to rotate and lift up the metal egg.
