Today's Lecture (10/10): |
| Summary: |
- A nice way of calculating the magnetic field
created by a current is Ampere's Law, which is similar to Gauss's
Law for electrostatics. Rather than define a closed surface, we draw
a closed loop. Then the integral of B along the loop can be found
from the amount of current going through the loop.
This is only useful for highly symmetric situations, such as a wire
or a coil.

Diversion-of-the-week: |
There are no end to the interesting physics
experiments that you can find on the web. Here's another one involving
a cd
and a microwave oven. I can't guarantee this is safe, so you may
just want to watch the video clip.
