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.

Faraday’s Law: Alternating Current

Experiment #12 from Advanced Physics with Vernier — Beyond Mechanics

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.
