How does a dynamo generate electricity?
A dynamo passes a magnet past a coil. The movement of the magnet past the wire causes eddy currents to develop which cause electrons to align and move through the wire. If there is enough wire and a strong enough magnet, the current (flow of electrons) is enough to become useful and power a device. It is the growing and shrinking lines of force that cause the electrons to develop this alignment and therefore the electric current.
