idea-2 school project: wind turbine model

wind turbine model :
This wind turbine model makes its electricity with a simple generator which produces pulses of current, or
alternating current. It does so by passing strong magnets over coils of fine wire. Each time a magnet passes
over a coil, the coil becomes energized with electricity. With 4 coils connected together in series, the result is a
quadrupling of the voltage.
This is the simplest and possibly most efficient way to generate electricity, and is the same basic principle used
in almost all wind turbines, even the large scale commercial ones. The electricity from a wind turbine varies with the wind speed, so to make practical use of it, you must be able to store it in batteries, or change it into a form that gives a stable, constant voltage. Usually, electricity from wind turbines is converted from alternating current to direct current, which can be used for battery charging.
