This module provides an introduction to magnetism including the nature of magnetism, magnetic fields, and magnetic materials. Electromagnets and permanent magnets are also presented using a combination of video and animation allowing the student to gain a better understanding of magnetic field theory. The Hall effect sensor is also introduced in this module.
