Whenever there is a change in the number of magnetic field lines passing through a loop of wire a voltage (or emf) is generated (or induced) in the loop of wire. This is how an electric generator works. The phenomenon is known ... where F is the magnetic flux given by the closed integral of the dot product B 0 dA.

If your metal car moves over a wide, closed loop of wire embedded in a road surface, is the magnetic field of the Earth within the loop altered? Does this produce a current pulse? Can you think of a practical application ... If you change the magnetic field in a closed loop of wire, what will you induce in the wire?

In a circular wire conducting a current, ... From these Michael Faraday (1791-1867), a English chemist and physicist deduced: the line integral of an induced electric field around a closed path, or the electromotive force e in the path, equals the time rate of change of magnetic flux across the area bounded by the path.
