Experiment 8 - Magnetic Field Induced by a Current-Carrying Wire

In this experiment you will investigate the interaction between current and magnetic fields. You will:

  1. Determine the direction of the B field surrounding a long straight wire using a compass (Oersted's experiment)
  2. Find the induced voltage in a small inductor coil, and show that the magnitude of the B field decreases as 1/r.
