Electromagnetic waves are widely used for various purposes in the modern age. However, the effects of electromagnetic waves on the human body are still largely unknown. In particular, there is a lack of basic research data in the intermediate frequency range of 300 Hz to 10 MHz compared to other frequency bands, and further research is needed. Previous studies have suggested that magnetic fields with a frequency of 400 kHz and a magnetic field strength of 10 A/m affect locomotor activity and brain matter in living organisms. In this study, we investigated the effects of a magnetic field of 25 A/m, which is stronger than the previous study, on locomotor activity and brain matter. As a result, we report our findings suggesting that magnetic fields reduce the amount of locomotion in the organism by about 30% and change the amount of monoamine neurotransmitters secreted in the brain.
