Jovan Marjanovic, the electrical engineer, has published the new paper in which he presents simple mathematical proof of Free Energy:
The Case in Electro-Magnetism Where Newton's Third Law is Not Valid and Getting an Energy Surplus in an Electro Generator
With simple formulas in electromagnetics it can be proven that Third Newton's law is not valid in all cases for electrical charges. Easy proof that electrical generator with high voltage achieved by high RPM have energy surplus in comparison with another generator with low voltage and high current.
