-
To make the electromagnet stronger and pick up more paper clips, they could increase the number of coils of wire wrapped around the iron core and increase the electric current flowing through the wire.
-
They are missing a battery as a power source. They could improve the electromagnets by wrapping the wire with more coils and increasing the voltage.
-
To build a hydroelectric dam that creates the most electricity, we could:
-
Increase the flow rate of water by ensuring a larger reservoir or optimizing water discharge.
-
Use a more powerful turbine design that efficiently converts water flow into mechanical energy.
-
Select magnets with stronger magnetic fields to enhance the electromagnetic induction process within the generator.

VI. Electromagnet & Generator Questions
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?
