Today in class we made an experiment that based on Faraday’s law of induction. He discovered it in 1831. This law states, “The induce electromotive force in any closed circuit is equal to the negative of the time rate of change magnetic flux through the circuit.” It is basic law of electromagnetism that shows how magnetic field will interact with circuit to produce electromotive force. During this experiment we produced electricity by shaking device that was consisted of magnet and wires. When we shacked this device magnet were going back and force trough the wires. That is why we generated electricity. In addition, almost the same technology is used by wind plants. As the result of this lab we figured out that as faster we shake more electricity we produced. Here is some data.
