A bstract : Exposure to extremely low‐frequency magnetic field (ELF‐MF, 50 Hz, 0.5 mT) for seven days did not change spontaneous motor activity of rats in the open field compared to sham‐exposed animals. Pre‐exposure to ELF‐MF decreased locomotor and stereotypic activity induced by amphetamine (1.5 mg/kg body weight) and accordingly increased the resting time compared to sham‐exposed and amphetamine‐treated rats. Vertical activity (rearing) of these two groups was similar. Our results indicate that ELF‐MF has different effects on some parameters of amphetamine‐induced motor activity, probably due to brain region‐specific effects on catecholaminergic systems responsible for movement control.
