How does an electric generator produce electric current?
There are two main types of generators. Direct-current (DC) generators produce electric current that always flows in the same direction. Alternating-current (AC) generators, or alternators, produce electric current that reverses direction many times every second. Both kinds of generators work on the same scientific principles. Every magnet has a field of waves around it. Electric current is generated if this magnetic field is disturbed. The electric current can flow along a closed loop of wire. The magnetic field is disturbed by any form of physical motion or force. So electric current will flow through a circuit of wire is a magnet nearby is disturbed by motion or force. Pieces of ferromagnetic metals such as nickel or steel can be made to vibrate near the magnet and this will keep its magnetic field in flux, with a continuous and consequent flow of electric current in a circuit of wire.
