Ok, Ok, OK!

These threatening emails are getting serious!

Here are the old lecture slides (Dr. Gauthier's) concerning Polarization, for those who missed the class.

Final Exam Redacted Version

Probably by the time you've studied every possible permutation of the questions in the redacted version of the exam you will be more than ready for the real exam.

Test #2 Remarking and Solutions

Folks,

Deepak was last seen under a bus.

Ok, he made amends and has corrected the marking.

The average mark is now 69%, still not my cup o' tea, but not bad. I will return the tests tomorrow.

Meanwhile, you might want to check out the official solutions.

Other PA Sessions this week.....

....should go to their usual location (4124ME).

Please go to room 340 in the Azrieli Pavillion today for your PA session. Note that is not the Azrieli Theatre --- don't get confused.

Upcoming Lectures

Some slide material based on Dr. Gauthier's old slides may be useful for the upcoming lectures. I will probably modify/skip these on the fly during the lecture. Depends on how hot the room is!

March 21, 2012 Lecture Summary

We looked at:

Magnetic Vector Potential

The Magnetic Dipole

Force on a Magnetic Dipole

Ring Of Current Mathematica Solution

Here is the Mathematica solution for the magnetic field generated by a ring of current, on the axis of the ring of current.

PASS Mock Test #2

Rachel sent me word that there will be a mock test tonight in 112PA starting at 5:30pm. The mock test will be repeated on Thursday starting at 1:30pm (I assume in the same location).

Sample Questions for the Midterm

Folks, as requested, here are a few questions to get you thinking:

Ohhhh.......So Now It's MY Fault?

Ok, I am not disagreeing. You're a smart bunch and I was fairly shocked at the scores.

Please leave some (anonymous) comments that will help me help you to score better on the next test.

Let me know what you think was wrong with the first test, or why the scores were so low.

I am listening.

Solutions to Test #1

I posted the solutions to the first test. Please review them, and let me know if you see any problems.

Lecture Summary for March 2, 2012

Today we discussed again Postulate #1 for magnetostatics, and what sort of problems can be tackled using it.

We moved on to Postulate #2 for magnetostatics. We did a few examples of problems or situations involving forces on current-carrying conductors.

We looked at Lorentz's force equation.

We went over the solutions to Test #1.
