Today, we'll introduce the idea of magnetism with several demonstrations. We'll learn how magnetic fields and electrical charges interact. We'll learn the formula for force on a moving charge in a magnetic field.  We'll also learn the right hand rule to figure out the direction of the force.  Finally, we'll learn about the shape of the path of a moving charge in a magnetic field and how to quantify it.  We'll discuss an application of this concept.

If you missed our initial introduction of magnetism, you can watch the following video to get some of the material:

Homework: If you have not done so already, skim through sections 19.1-19.3 on pages 657-667 in your textbook. Answer conceptual questions 4-7 (p 689) and exercises 5, 7, and 9.  (solutionsIf you need help understanding the first right hand rule for the force on a moving charge in a magnetic field, watch the following video:
