Physical Science: Properties of Magnetism
by Texas Instruments - Data Collection with Probes Lesson

Objectives

  • Students will describe the magnetic field around an electromagnet.
  • Students will relate the strength of a solenoid-type electromagnet to the number of turns of a wire on the electromagnet.

Vocabulary

  • magnet
  • magnetic field
  • electromagnet
  • solenoid

About the Lesson

In this lesson, students will create a solenoid-type electromagnet using two different methods of coiling the wire around the core. They will use a sensor to determine the relationship between the number of turns of wire and the magnetic field strength for each method.
