With the electric motor it was demonstrated how electricity can cause motion. What if instead of using electricity to run the motor, we spin the electromagnet ourselves.? What will happen? Will we make electricity? The answer is yes! Disconnect the battery from the motor and replace it with a low current light bulb. Then come up with a method of spinning the electromagnet quickly. This can be done using a turbine like the one below. Other possibilities are bike wheels and hand cranks.

The turbine is the method which is used by dams. They let rushing water spin the electromagnet and produce electricity. This is also how coal plants and nuclear reactors work. These systems create steam by the burning of coal or by nuclear reactions that heat water. Steam can produce a lot of pressure. The steam is then used to spin a turbine.
