magnetic variations

Monitoring and analysis of technical low-frequency magnetic noise in Kyiv

Artificial magnetic field variations study results carried out in Kiev are represented in this publication. Artificial component of magnetic field in frequency band from 10-6Hz to 1 Hz has been experimentally studied for the first time. It was shown that man-made variation sources with intensity from tens to hundreds nanotesla have electrical and ferromagnetic nature mostly. Daily rhythm of artificial variations is caused by people activity timetable.
