Likewise, a wire passing through a magnetic field creates an electric current within the wire. This is the basic principle that allows electric motors and generators to operate. In the Earth (see ...
David Bressan is a geologist who covers curiosities about Earth. Without its magnetic field, life on Earth would not be possible since this shields us from harmful cosmic radiation and charged ...
the result is the generation of an electric current, which in turn results in the generation of a magnetic field. The researchers noted that models describing flows within the Earth typically do ...
New research led by Monash University geologists suggests that electric currents generated within the earth play a role in their formation. The researchers noted that pure gold is often found in ...
