"EZIE is the first mission dedicated exclusively to studying the electrojets," Larry Kepko, an EZIE mission scientist at NASA's Goddard Space Flight Center in Maryland, said in a statement. "It does ...

As with all currents, the induced current creates a magnetic field around itself. Note that this magnetic field opposes the original change. For example, if a magnet is moved into a coil of wire ...

How a tokamak works: The electric field induced by a transformer drives a current (big red arrows) through the plasma column. This generates a poloidal magnetic field that bends the plasma current ...
