Today's Lecture (10/15):Summary:
- If we have a loop of wire, there is a current induced whenever the magnetic flux through the wire changes. This is called Faraday's Law. The potential around the loop is related to derivative of the flux.
The current current can be determined by Ohm's Law.
- An easy way to figure out the direction of the potential, and therefore the current, is by using Lenz's Law. This law says that the current around a loop will try to counteract any changes in flux. (Whether it succedes or not depends on Ohm's law.) You will need to use the right hand rule for fields caused by currents to determine this.

Diversion-of-the-week:This week I'm encouraging you to explore methods of creative thinking. I know, you're probably thinking creativity is not something that can be learned! But shouldn't you give it a try. The creativity web may just give you a few ideas.
