To Study for the Exam

Doing problems that are harder than what is on the exam can STILL help you! Even if you get totally lost and confused half way through the problem this is IN FACT better than doing 20 easy problems you already knew how to do to begin with! Make sure you know:
1) How particles behave in the prescience(sp?) of a magnetic field (how does that differ if the charge is positive or negative)?
2) What kind of magnetic fields are produced from different sources (i.e. a current carrying wire, a moving charge, ect.)
3. How to do simple polarization problems
4. RC, RL, RLC circuit problems
5. AC circuit problems, WITH PHASORS!!!
6. Motional EMF (the thingy with the moving rectangle of wire into a magnetic field)
7. Calculating the magnitude and DIRECTION of the magnetic field from any source
8. the relationship (both VECTOR and otherwise) between the E and B-fields in a EM-wave

Mmmmmm.....how did I come up with this list?.......(that is a rhetorical question, please do not answer)
