There’s something almost magical about magnetism. As people, we’re amazed by a magnet’s ability to affect metals like iron, nickel and cobalt without touching them. Electromagnetic induction occurs when a circuit with an alternating current flowing through it generates current in another circuit simply by being placed nearby. An alternating current is the kind of electricity flowing through power lines and home wiring, as opposed to a direct current, which we get from batteries.
This past weekend I was at the North Shore with my boy Kyle Kekina and we drove past the wind generators. The wind pushes the turbine causing the wires to move around the magnet which induces a current. The current is induced by the spinning of the coil. The wind provides as a energy for the wind generator. This week was very fun to see the wind generator in action because the north shore was very windy so the turbines were moving a lot.
