Dr. Forrester discusses the properties and uses of magnets by classifying objects as magnetic or nonmagnetic.

Dr. Forrester teaches that magnetism is a force that pushes and pulls on other objects. She defines: gravity, attract, and repels. She teaches about forces that attract or repel other objects and lists principles of magnetic behavior.

Learn how hybrid stepper motor works in this video on hybrid stepper motor basics, covering the rotational magnetic field as well as the rotor and stator.

Earth's Magnetic Field explores the importance of Earth’s magnetic field by examining the crucial role it plays on the planet.

“Effects of Magnetic Fields” reviews the concept of a magnetic field and demonstrates how a magnetic field can be shown using simple iron filings and bar magnets.

Magnetic Forces explains the properties of magnets by describing characteristics and defining magnetic forces.

The Earth’s Layers examines the physical makeup of the earth by exploring the earth’s core, mantle, and crust.
