prof. Koch,
Can you add the lecture notes for Tuesday, October 26th
I have posted the 10/26 lecture notes.
when will you post the solutions?
well i mean answers
I will post solutions after the review session on Sunday at noon - 2 pm in ESS 001. (It will be recorded and available later on Echo 360.) Because you have all the material available to you (book, lecture notes, your HW solutions) and the time is not limited as it is in an actual exam, I want you to work out the practice problems before then without knowing the answer. You'll learn more that way.
For number 2, I know we can use F=BIl but we are not given B. How do we find be without I?
The current in edach straight wire generates a B field. Therefore, the B field of one of the wires can exert a force on the flowing current in the other wire, and vice versa. I used a video demonstration of this in class. Also see SV8, Ch. 19.8.
Professor,
can you review as to why a metal ring will jump up when an induced current is applied to it, as in Oct. 7th lecture video?

Dear Professor Koch,
Can you please post up a link to practice midterm 2?
BLACKBOARD is not working right now...so I think none of us can see it.
I just posted a link on the blog.
