Week of 3/18

Three students stopped by my Wed. office hours. We worked through one challenging Sapling problem that involved finding the magnetic field due to two rotating discs. We were able to solve this problem by 1) using symmetry, 2) working through it piece by piece, and 3) relating magnetic field problems to electric field problems. We also re-solved some conceptual questions embedded in the lectures - these related to the right-hand rule. With their third exam coming up shortly and the information becoming more difficult, I'm sure more students will have questions in the upcoming week.
