Electricity and Magnetism. Physics 102 Professor Lee Carkner Lecture 8. Electricity and Magnetism. In E&M, we will deal with forces that depend upon charge Charged particles generate E&M forces Stationary charges exert an electric force E&M forces only affect charged particles. Forces.

F = k q1 q2/r2
opposites attract, like repel
Rubbing a piece of rubber with fur transfers the electrons from the fur to the rubber due to friction.
Both Metal Rods Now Charged
Charge will move from one conductor to another
Induced Charge on Metal
A charged conductor will split the charge on a near-by conductor
Metal becomes positive
Electrons pushed to ground
A charged conductor will push out the same charge to the ground, leaving the other conductor with an opposite charge
