Physics 3310, Electromagnetism
Instructors: Steven Pollock, Stephanie Chasteen, and Darren Tarshis
Jean-Baptiste Biot and Felix Savart (above) collaborated on developing a force law for magnetic fields. The Biot-Savart Law is the magnetic equivalent of Coulomb's Law. It's still an inverse square law, but is rather more complicated in its vector nature. We'll study the Biot-Savart Law this week.
Week 10 (Mar 17-Mar 21):
We are moving on to discuss time independent magnetic fields. Magnetic fields cause forces on moving charged objects via the Lorentz Force. We will concentrate primarily on how to calculate B-fields from given current distributions. (Oh, and of course, magnets are fun!)
Special notes:
- Exam is graded, distribution is on the "exam info" link. I'll return them in class Friday, you can see your own score in "my grades" on CULearn. I have also posted my solutions on CULearn. I know it was long, but the average was 72.4% (just 3 points lower than the first midterm) with a more "normal" looking distribution. Looks good!
- Check out these links for simulations to show vector fields in 2D and 3D and another (emstatic) in 2D.
- OFFICE HOURS:
Mon 4 PM, in the Tutorial bay in the basement (with Stephanie Chasteen)
Tues (3:30-5 PM, 11th floor) (Exam week, I'll just be in my office)
Friday, 4 PM, (in a Tutorial bay in the basement), Darren Tarshis runs his "3310 Tutorial".
(NOTE: These are temporarily cancelled - there won't be one Friday before the exam, and there won't be one Friday before spring break! If people are interested let me and/or Darren know, we can start this up again *after* the break)
- Reading: Chapter 5 this week
- Written Homework: Always due Wed at the start of class - see the assignments link (always available on the upper left).
I welcome your comments on the class and this website.
