In the laboratory school of about 10 amperes current created in the shavings circle with a diameter of several centimeters (photo), currents of 40 or 400 thousand amperes (even more) recorded in the crop circle with a diameter of about tens of meters (ph).
Katika shule ya maabara ya amperes kuhusu 10 sasa umba katika mduara shavings na mduara wa sentimita kadhaa (photo), Currents ya amperes 40 au 400,000 (hata zaidi) Imerekodiwa katika mduara wa mazao na mduara wa kuhusu makumi ya mita (ph).
