Dr. Forrester defines electromagnetism and magnet by identifying the relationship between electricity and magnets and how they come from the same force.

Dr. Forrester examines the discovery of electricity by creating a timeline. She also shares information about Thomas Edison and his invention of the light bulb.

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.

In this video, we'll look at how an electric motor works- specifically, the DC motor. We'll discuss the different parts of the motor, and how they work together to create movement.
