Physics 132 - General Physics II - Professor Bunson
Fall 2001
Today's Lecture (10/12):
Summary:
  • There are basically four common situations where you can use Ampere's Law. These are a wire, a coil (solenoid), a coil in the shape of a donut (toroid), and a wall or sheet of current. The Amperian Loop for each of these situations are the following.

    Wire: A circle drawn around the wire.

    Solenoid: A rectangular loop with one side inside the solenoid and one side outside.

    Toroid: A circular loop that is completely within the donut.

    Sheet: A rectangular loop with two opposite side that are equi-distant from the     sheet or with one side that is exactly in the middle of the sheet.

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.
