Magnetic Field Coil

Lab Summary

Use a current sensor and magnetic field sensor to understand some of the factors affecting the electromagnetic field strength within a solenoid.

Theory

This activity is designed to provide students with an understanding of some of the factors affecting the electromagnetic field strength within a solenoid. Throughout the activity students will:

  • Build foundational understanding of how magnetic field strength inside a coil is related to the magnitude of current carried through the coil wire.
  • Explore the relationship between and the number of turns of wire in a coil and the magnetic field strength within the solenoid.

Method

Students gain experience conducting the following procedures:

  • Measuring and recording the magnitude of the magnetic field within a coil.
  • Plotting a graph of Magnetic Field versus Turns in a coil to determine the relationship between the magnetic field strength and the number of turns in a coil.
  • Plotting a graph of Magnetic Field versus Current in the wire of a coil to determine the relationship between magnetic field strength and the current flowing through a coil.
