EFFECT OF THE MAGNETIC FIELD OF A SOLENOID ON THE CENTRAL NERVOUS SYSTEM
Yu. A. Kholodov, G. R. Solov'yeva · 1971
1971 Soviet research proved magnetic fields from electromagnetic coils measurably affect rodent brain function and behavior.
Plain English Summary
This 1971 Soviet research investigated how magnetic fields from solenoids (electromagnetic coils) affect the central nervous system in rodents. The study used EEG monitoring and conditioned reflex testing to measure neurological changes from magnetic field exposure. This represents some of the earliest scientific investigation into how artificial magnetic fields might influence brain function.
Why This Matters
This pioneering research from 1971 represents crucial early evidence that artificial magnetic fields can measurably affect nervous system function. While conducted decades before our current EMF-saturated environment, Kholodov's work using solenoid-generated magnetic fields established fundamental neurological impacts that remain relevant today. The science demonstrates that magnetic fields don't need to be thermal (heating) to create biological effects. What this means for you is that the magnetic field components of modern devices - from wireless chargers to induction cooktops to smart meters - may influence brain activity in ways we're still discovering. The reality is that this Soviet research, conducted without industry influence, helped establish magnetotherapy as a legitimate medical field while simultaneously raising questions about unintended exposures.
Finding
In the majority of the experiments in the experimental mice by comparison with the control mice conditioned reflexes were inhibited. (Fig. 2): therefore the conclusion is drawn of a predominantly inhibitory effect from a continuous sinusoidal magnetic field.

The reaction to the effect of the magnetic field can be different (inhibition, excitation), confirming the general law of the dependence of the reaction on the functional state of the organism, the species of animal, the field parameters, and so on. The ambiguity of the field effect can find various regions of application in magnetotherapy. The identical effect of a magnetic field does not always cause the recorded reaction. The visual EEG-reactions were recorded in 61% of cases in rabbits subjected to 110 effects of a variable field, indicating the relative weakness of the magnetic field as a stimulus and the necessity of repeated effects to obtain a stable effect.
