lab 7 - Faraday's Law of Induction

Overview

1. Objective:
   Methodology
2. Questions
   1. Why is the sign of the second voltage peak opposite to the sign of the first peak in voltage versus time graphs?
   2. Why is the voltage zero when the coil is passing through the exact center of the magnet?
   3. With a load resistor connected to the induction wand, why is the second peak voltage smaller than the first one in the voltage versus time graph? Is this voltage emf?
   4. Why does the wand slow down significantly when a load resistor is connected?
   5. Why do you need to include both peaks in the integration of power versus time graph to determine energy?
   6. What are the possible errors in this experiment?
