Physics 3310, Electromagnetism
Instructors: Steven Pollock, Stephanie Chasteen, and Darren Tarshis
Here is a picture of a Farady cage large enough to test the electromagnetic properties of a bus. (For example, how does a cell phone work if it's inside the bus?) This screened room is made by Frankonia. They also make entire rooms for special situations. Check out their copper room.
Week 4 (Feb 4-Feb 8):
We are finishing Ch 2. This week, we discuss the interpretation of electric potential and the energy stored in static electric configurations of charge (both with and without conductors around) The fact that the curl of a static electric field is always zero tells us that a static electric field always can be written as the gradient of a potential function. (And, finding the potential is often easier than finding the E-field directly from Coulomb or from Gauss)
Special notes:
- Out of 9 people who took the online survey and who have gone to the tutorials, 7 of them spontaneously mentioned them as being very useful, that they've learned a lot, and enjoyed them too. (We have regular attendance from roughly half the class) So, come join your classmates, don't miss out!
- Have you registered your clicker yet? Please do so!
- Check out these links for simulations to show vector fields in 2D and 3D and another (emstatic) in 2D.
- UPCOMING OFFICE HOURS:
Mon 4 PM, in the Tutorial bay in the basement (with Stephanie Chasteen)
Tues (3:30-5 PM, 11th floor) will be my regular office hours/hw session.
Friday, 4 PM, (in a Tutorial bay in the basement), Darren Tarshis runs his "3310 Tutorial".
- Reading: We're finishing Ch. 2 this week (and perhaps will start Ch. 3)
- 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.
