Basics of an electrical generator		 The aurora, like a neon sign, needs a power supply to trigger the electrical discharge process that leads to the emission of light. Power often is supplied by a generator. A generator consists of an electrical conductor (a copper wire coil) and a magnet (a magnetic field). Where is the auroral generator? How does it work?

The ultimate source of energy for the aurora is the sun.
