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.

Pseudo-self-action and equivalence rule in magnetostatics
S. A. Gerasimov, V. V. 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.

Keywords: non-reserved system, moment of sorce, magnetostatics, reserved system.
