1 Equation sheet posted. RHR (using thumb for current) shows current must flow downward: Ans. A

2

3 A= i B= ii, etc. Ans iii=C

4 Ans: ii A= i B= ii, etc.

5

6 A= i B= ii, etc. Adjacent coils attract magnetically, no electric force. Opposite sides repel magnetically, no electric force.

7 In Ampere’s law, Gauss’ law, etc. :
If we let loops and surfaces get infinitesimally small, we get relationships for derivatives of the fields. There are four relationships, called “Maxwell’s Equations” These are what we (in physics 161) know now. They are still incomplete: we will fix them in the remaining weeks.

8 Maxwell’s Equations (corrected)
Nothing would demonstrate your love of, and dedication to physics like a…. Maxwell Equations Tattoo !

9 And… they look great on chicks as well as dudes…
