Daily quiz: Biot-Savart 2

Today, after watching the homework videos below, we'll work on some Ampere's Law Problems.  Chapter 28:
    Required:  27, 28, 7, 9, 12, 15, 16, 18, 19
    Enrichment:  20
With any time remaining, work on AP Problems from the next post.  

Homework:  Test on Magnetism Tuesday, February 13th.  Make sure you've watched the first two Ampere's Law videos which were in the last post.  Then, watch the following videos on examples of the application of Ampere's Law.  The first example is how to find the magnetic field inside a current-carrying wire.  Can you find the magnetic field outside the wire?  Try this problem and finish the graph that lasseviren1 started - B vs. r.

Ampere's Law: B inside a current-carrying wire (lasseviren1)

Check your answer starting at 4:20 of the next video, and then watch the rest of the video which gives an example of finding the magnetic field in a coaxial cable. 

Ampere's Law: B in coaxial cable (lasseviren1)

Watch the following video showing two more examples of Ampere's Law.  After you watch both examples, finish the second example by finding the magnetic field as a function of r outside of the wire and finish the B vs. r graph.
