Physics 201- Introduction to Electricity & Magnetism
November 1- Magnetic Forces






  Do magnetic fields exert a forces on electric charges?  What did your experiment show you?

We want to define magnetic field, much like the electric field, in terms of the force on a charged particle.

Units of magnetic fields: 1 tesla= 1 N s / C m = 104 gauss

Earth's field is approximately 0.5 gauss, magnets in a lab are a tesla or so.
