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.


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.
