Day 97: Finishing the Magnetic Force on Moving Charges

Today was mostly a long test. It happens. The unit on the electric field is the longest unit I teach, and I'm not sure how to split it up. It would make sense to start it at the beginning of a semester, but it just didn't work out that way this year. The electric field unit is definitely one I have to think more about.

We whiteboarded a few problems figuring out the direction of the magnetic force. So many questions. Some were just trying visualizing the right-hand rule, which is very difficult sometimes. The others were deep questions about the consequences of the magnetic field. Students were starting to ask questions that would lead to the Hall effect or magnetic induction, and I just had to evade the questions.
