Chapter 30:

In order to use Faraday's law you must be able to calculate flux_B. As _B = B^.dA, this requires being able to calculate B and dA. A quick review of 30.7 and Ampere's law, are probably in order. You might also want to make sure you know how to set up integrals to find the areas of some simple geometric shapes like circles, squares, triangles, rectangles. This will help you in finding the differential area element.

Know how to find displacement current and use Ampere-Maxwell's equation to find B.
See displacement current Problems pg24 of practice tests

Know what paramagnetic diamagnetic and ferromagnetic mean. Know What M, H and B represent. Know what magnetic susceptibility and magnetic permeability mean. Know how M depends on temperature and what a Curie temperature is.

Chapter 31:

Lenz's law:

You must be able to determine the direction of current induced in a loop of wire. Go through the text and figure directions for every picture for the chapter 31 problems until you are sure you know what you are doing.
Faraday's law

E = - d _B/ dt
Be able to find E when B is changing, I is changing, A is changing, or angle is changing. Be able to find E when a bar is moving, the whole loop is moving or the magnet is moving.

Eddy currents:

Know who Eddy is, what his favorite shape looks like, and what direction he is going.
 

It has come to my attention that some of you have not seen a particular notation that is on the exam.  The expression "exp(x)" is the exponential of x. It is a little hard to write in a text email message but it looks something like   exp(x) = e to the x power.

 I hope that clarifies that for everyone.
