Magnetism

For the Quiz you will need to understand the following:

• Basics of Magnetism-How the direction of a field is defined...
• How the direction and magnitude of a force is determined on a moving charge (+ or -) in a magnetic field
• How the direction and magnitude of a force acting on a current carrying wire is determined in a magnetic field
• How to apply Newton's Laws to those forces
• How to determine the direction of the magnetic field created by a current carrying wire
• How to use Ampere's Law for determining the magnetic field

What is the mass of the electron and HOW do we KNOW?

Items to discuss in the HOW.

D means discuss data, R means reference from past lab, T means theory.
