The article reveals that intensity of low frequency electromagnetic noise (0,05 Hz-20 Hz) is caused by industrial noise. Intensity of electromagnetic and acoustic noise generated by municipal transport was compared. The population in large industrial cities continuously suffers from low-frequency industrial electromagnetic noise comparable to an average geomagnetic storm.

Keywords: geomagnetic field, moving of magnetic mass, industrial variations of field.
