Physics Traditional: Unit 10 "Magnetism & Induction"

10- Magnetism & Induction
Summary: In the last unit we learned that electric current is electrical charge in motion. In this unit we learn that any time charges move, a magnetic field results. The reverse is also true which allows us to use magnets to make electricity and electricity to make magnets – the process of induction which drove the industrialization and the modern world we live in. We also do a project this unit.. In this unit you will learn about the basis for all magnetism, domain theory, how earth’s magnetic field works and how it protects us from deadly solar radiation, very simple induction math, how compasses and transformers work and about magnetic fields. You will also learn, that magnetic fields, the direction of electrical charges including current, and the forces that come from these two interacting are always at right angles.You will get to do a magnet lab and see simple transformer and a cool demo with something called a Thompson coil.
