Next Stop: MAGNETISM!

Posted in 8th Grade at 12:40 pm by slesscience

8th Graders,

The next topic in class is short and sweet. We will be discussing it this week in class and there will be a quiz on Friday related to it. Most of you should already have a good understanding of Magnets and Magnetism and we have already discussed how they can be used to generate electricity.

Here are the topics you must know for the quiz:

Relate the terms Magnetic Force, Magnetic Field, and Magnetic Poles.
How does a compass work?
How do you make an electromagnet?
Name and explain one application of electromagnet.
What is a transformer? How are they used?
