8. What are two things from the video that they did to make the electromagnet stronger and pick up more paper clips?
Type Answer HERE:
9. An electromagnet is created when we run an electric current around an iron core. Look at the following investigation from a student. What are they missing and what could they do to make it better?
Type Answer HERE: they are missing a battery. they could improve the electromagnets by, wrapping the wire with more coils and increasing the voltage.
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?

8. Two things that were done to make the electromagnet stronger and pick up more paper clips were: increasing the number of coils of wire around the iron core and using a stronger power source (higher voltage).
9. They are missing a battery. They could improve the electromagnet by wrapping the wire with more coils and increasing the voltage to enhance the strength of the magnetic field.
10. To build a hydroelectric dam that creates the most electricity, we could:
1. Increase the flow rate of water to enhance the movement of the magnet and thus generate more electricity.
2. Use a larger or more powerful magnet to increase the magnetic field strength, which would lead to a greater induced current.
3. Optimize the design of the turbine to ensure maximum efficiency in converting the kinetic energy of water into mechanical energy for generating electricity.
