["Open field" rat behavior following exposure to a magnetic field].
The influence of the magnetic field on a complex physiological reaction in the "open field" test was studied in experiments on 160 rats. The behaviour in the "open field" was observed within three consecutive days simultaneously of control rats and those subjected directly before each test to a three to four hour general effect of a weakly pulsing magnetic field with a 0.3 T induction or a strictly constant magnetic field of 1.6 T. Individual behavioural reactions to the MF action were characterized by great variability and could be of different direction. According to mean data, the 0.3 T MF action depressed motor and investigating behaviour of the rats in the "open field". An increase of magnetic induction up to 1.6 T, far from enhancing the inhibitory effect, showed a tendency towards activation of behaviour in the "open field". Apparently, in conditions of the intensities used, pulsation is a biologically more significant characteristics of the magnetic field than the magnitude of induction.
