Faraday’s Law: Alternating Current
Experiment #12 from Advanced Physics with Vernier — Beyond Mechanics
- Subject
- Physics
Introduction
The focus of the previous experiment is the induced emf in a coil produced by a magnet moving through the coil. In this experiment, you will examine the relationship between an alternating current in a primary coil and the induced emf in a secondary.
Objectives
In this experiment, you will
- Collect current vs. time and potential vs. time data for a pair of solenoids.
- Explain how the magnetic flux through the secondary solenoid depends on the current in the primary.
- Relate the shape of the graph of potential vs. time in the secondary to that of current vs. time in the primary.
- Calculate the induced emf produced by alternating current in the primary and compare this to experimental findings.
Sensors and Equipment
This experiment features the following sensors and equipment. Additional equipment may be required.
