"Because the m≠0 components of Earth's field produce no net force on charges rotating with Earth, they cannot be used to drive an electric current. However, the axisymmetric m=0 components of ...
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 ...
For over half a century, scientists suspected a quiet but powerful electric field might be influencing Earth’s upper atmosphere. Now, thanks to a daring rocket mission near the North Pole ...
While people go about their daily routines, the planet is in perpetual motion, rotating through its own magnetic field. A new ...
These auroral electrojets push about a million amps of electrical charge around ... part of a vast electric circuit that ...
