Role of eddy currents in lifting force creating for an autonomous emitter of radio-waves A. I. Nikitin, I. O. Leipunsky, T. F. Nikitina Institute for Energy Problems of Chemical Physics, Russian Academy of Sciences 38/2, Leninsky av., Moscow, 117829, Russia E-mail: anikitin@chph.ras.ru For test a hypothesis for ball lightning levitation over conductor surface due to eddy currents, induced in conductor, experiments for measuring of the force, repelling a coil from a copper plate, were conducted. The coil of diameter 5.2 cm was fed with alternating current of frequency 440 kHz at a power 4.6 kW. It was found that this force at a distance 3 cm does not exceed 0.1 N and sharply decreases at shifting of the coil from the plate. This excludes eddy currents as a reason of ball lightning hovering. A new hypothesis is proposed that ball lightning levitation may be explained by existence of corona discharge on its surface.

Priadchenko Southern Federal University, 5 Zorge str., Rostov-na-Donu, 344090, Russia E-mail: GSIM1953@MAIL.RU The torque of an unclosed system exerted by the Ampere force equals the sum of Biot-Savart torque acting on the same system and the Biot-Savart self-torque by means of which the system acts on itself. Since the Ampere force satisfies the equality and collinearity of action-reaction that the total torque of both forces is equal to zero in a closed system.
