Background: An electric generator is a device that changes kinetic energy to electrical energy through electromagnetic induction. A simple diagram of an electric generator is shown in Figure below . In a generator, some form of energy is applied to turn a shaft. This causes a coil of wire to rotate between opposite poles of a magnet. Because the coil is rotating in a magnetic field, electric current is generated in the wire. If the diagram in Figure below looks familiar to you, that's because a generator is an electric motor in reverse. Look back at the electric motor in Figure above . If you were to mechanically turn the shaft of the motor (instead of using electromagnetism to turn it), the motor would generate electricity just like an electric generator. You can learn how to make a very simple electric generator by watching the video at the URL below. Making your own generator will help you understand how a generator works. Paragraph: In Chicago, the The Energy Conservation society has a neat system outside of their building. They have a bunch of machines you can sit in to watch slide shows. The way you power these machines is applying force to a turn shaft in them. The amount of energy used to power the slide shows is also less than the energy produced as well and gets stored. Given the paragraph above, please answer correctly the following question: Will increasing the amount of kinetic energy used to power the slide show machines increase or decrease the electrical energy generated?
The answer to this question is:
increase
