Physics: Magnetic Field of a Coil - Data Collection
by Texas Instruments - Data Collection with Probes Lesson


  • Students will understand the relationship between magnetic flux density and the strength of the electrical current.
  • Students will determine the value of the magnetic constant.


  • Magnetic flux density
  • Electric Current

About the Lesson

This lesson demonstrates the proportional relationship between the magnetic flux density at the center of a long, electrically charged coil and the strength of the electrical current. This is a more advanced experiment for high school students.
As a result, students will:

  • Create a closed circuit.
  • Determine a relationship from a graph.
  • Calculate the value for the magnetic constant.
  • Calculate percent error of the experimental value from the given true value.
