Teaching Notes W01D1 (Tuesday Only)
Overview
Any last minute changes for this class will be put at the top of this sheet, so the class leaders/TSG
Instructors should check here right before you do the class for last minute changes/problems. Questions
about the class? Email jbelcher@mit.edu or padour@mit.edu.
This is an exploratory class. We do this class on Tuesday Feb 7 and Tuesday Feb 21 in part because the
Mon/Wed and the Tue/Thur classes are out of phase because the term starts on a Tuesday. Inserting this
exploratory class at these two points keeps these sections continually in phase except for these two
exploratory classes. Both of these classes are done before the first experiment.
In this class, we want the students to become familiar with the phenomena of induced currents due to
changing magnetic flux. This is one of the most fundamental things we want them to bring away from
this course.
We will return to this concept later on in the course in quantitative detail. In this class we just want them
to see the phenomena, both with the class leader doing it and them doing it, both in reality and in a
simulation. After this class the student should have some idea of the phenomena itself, and of flux,
changing flux, and changing flux generating a current, and how these are linked. Our only goal is to
have them walk out with a qualitative understanding of these facts.
What you need to do to prepare:
Become familiar with the presentation. Know how to hook up the student Faraday’s Law experiment.
Take a look at the descriptions of the three large demo experiments we have for this class. All of the
previous can be found by going to the course home page at http://web.mit.edu/8.02t/www/ . Become
familiar with the Java3D application before the class:
http://web.mit.edu/viz/EM/visualizations/faraday/faradaysLaw/faradayapp/faradayapp.htm .
Technical Issues:
Java 3D Application: We are going to be having the students use a java application in class which you
should become familiar with before class. It is at
http://web.mit.edu/viz/EM/visualizations/faraday/faradaysLaw/faradayapp/faradayapp.htm
This application should run on your pc/mac. Right now it will not run in Athena clusters. If you have
any problems getting these to run on the machine you will be doing the presentation from, please email
jbelcher@mit.edu immediately and he will try to resolve it.
PPT Security Concerns: When you open up your ppt file from the 8.02_Spring 2012 drop box for this
class and for future classes, will may see the following dialog box. Choose “Cancel” when you see this.
