Abstract

Induction vector has temporal variations caused by changes of geomagnetic activity when the average amplitude of the MT-field is comparable to noise amplitude. Frequency characteristics of these temporal variations are studied for several Japanese observatories. Temporal variations cover a range from units to 1,000 and more seconds on observatories situated close to railways, powered by direct current. In other cases, these variations appear on shorter periods.
