Dosttameem (talk) 06:28, 13 July 2008 (UTC)Is it possible to get direct current DC on a coil if we put a metallic pin(directioned along the Earth's North-South) through the coil's center line? Theoretically, it seems that this way the magnetic field of the Earth to be inverted to electric current by the coil and to give us a DC current on the coil terminals. The amount of electric current could be related to the coil size... I need more information on this topic please!Dosttameem (talk) 06:28, 13 July 2008 (UTC)
