Physics: A Magnetic Attraction

by Texas Instruments - Data Collection with Probes Lesson


  • Students will map and describe the magnetic field around a permanent magnet or electromagnet.
  • Students will determine the direction and strength of the force a magnet exerts on a current-carrying wire or loop.


  • magnetic field
  • magnetic permeability constant
  • magnetic moment

About the Lesson

In this activity, students will investigate the relationship between magnetic field strength and distance.
As a result, students will:

  • Develop a mathematical model of magnetic field strength.
  • Use the model to calculate the magnetic moment of the field.
