The simplest complete circuit is a piece of wire from one end of a battery to the other. An electric current can flow in the wire from one end of the battery to the other, but nothing useful happens.

The induced voltage produces an induced current if the conductor is connected in a complete circuit. As with all currents, the induced current creates a magnetic field around itself. Note that this ...

I hope that you are never in a situation in which you are in danger from a downed, but live, power line. However, if that ever happens, the recommended safety procedure is to move away with tiny, ...
