1. Read (again) chapter 8, section 2 to review, and now I think, to understand, about how electricity and magnetism are related, and about electromagnets. Copy the illustrations and captions if you haven't yet done so, and try to explain to yourself or someone else the AS YOU READ list on page 233. The next thing we will learn about are motors, which combine electromagnets with permanent magnets to produce motion.
