8. Two things they did to make the electromagnet stronger and pick up more paper clips were increasing the number of turns in the wire coil and increasing the current flowing through the wire.
9. The student is missing the iron core to create the electromagnet. To make it better, they could use an iron core inside the wire coil to enhance the magnetism.
10. Three things we could do to build a Hydroelectric Dam that creates the most electricity are:
- Use a larger and stronger magnet to maximize the magnetic field strength.
- Increase the flow rate of water to spin the magnet faster and generate more electricity.
- Use a coil of wire with a higher number of turns to capture more magnetic field lines and generate a stronger current.
8. What are two things from the video that they did to make the electromagnet stronger and pick up more paper clips?

10. A generator is simply a device that moves a magnet near a wire to create a steady flow of negative charge. A great example of this is the hydroelectric dam. A hydroelectric dam is used to make electricity. We have a flow of water that spins a magnet within a coil of wire to create a current of electricity, which we then send out to homes everywhere. Using the image below and your knowledge of Generators, list 3 things we could do to build a Hydroelectric Dam that creates the most electricity?
