Tangent Galvanometer

The tangent galvanometer coupled with a compass is used to experiment with magnetic fields at the center of circular loops and to determine properties of the Earth’s magnetic field.

Topics and Objectives:

  • Investigate the magnetic field at the center of a current-carrying loop of wire.
  • Verify the right-hand rule for the field inside a current loop.
  • Explore the vector nature of magnetic fields.
  • Test the relationship between the current, the number of turns, and the magnetic field.
  • Determine the strength of Earth’s magnetic field at the lab’s virtual location.
  • Verify results using NOAA’s Geophysical Data Center and Google Earth.
