Faraday’s Law: Moving Magnet
Recommended for grades 11–16.
Introduction
You have learned that magnetic flux is the dot product of the magnetic field vector, B, and the area vector, A, for a closed loop,
. In this experiment, you will investigate how changes in the flux from a changing magnetic field affect the behavior of the mobile charge carriers in a conducting loop.
Objectives
In this experiment, you will
- Fashion a simple coil to collect data.
- Collect potential vs. time data for a magnet moving through a coil.
- Account for features of the observed graph of potential vs. time.
- Relate the induced emf to changes in the magnetic flux passing through a coil.
Sensors and Equipment
This experiment requires each of the following Vernier sensors and equipment (unless otherwise noted):
