Electricity generation
Here are some examples of electricity sources that make the coil turn in a generator.
Gas-turbines: Fuels are burned to create hot gases which go through a turbine (like a big fan or rotor), which in turn makes the coil of wire spin and electrons flow.
Hydro-electric power stations: Flowing water (usually from a dam) pushes against the turbine blades. This causes a rotor to turn, and the coil of wire to spin, making the electrons flow.
