February 17, 2012 Lecture Summary


As promised, we covered the continuity equation, current flow, the electric field in conductors with current, and resistivity and conductivity.

For those of you who took an early break, we also covered:

Magnetostatics: Lorentz force law; Hall effect; Ampere's law; Curl of a vector field; The magnetic vector potential; The Biôt-Savart Law; Applications of the Biôt-Savart Law: current ring, solenoid; Energy stored in magnetostatic field.
Magnetic Fields in Matter: Magnetic dipoles; Diamagnetic, paramagnetic and ferromagnetic materials; Magnetic circuits.
Faraday's Law: Faraday’s law and induced EMF; Lenz's law; Eddy currents; Inductors

You might want to catch up on all that material during reading week.
