This item is a beginning tutorial on generators and motors, appropriate for introductory high school physics.  Fully illustrated, it explains how current flows through a conductor and how motors change electric energy into mechanical energy.  The author devotes careful attention to coils and how they are used to cut through lines of force and strengthen a magnetic field.   The latter half of the tutorial illustrates both AC and DC current generators and motors, with graphs to show the current wave cycles of both.  

This resource is part of the Molecular Expressions project at the National High Magnetic Field Laboratory at Florida State University.

This resource is part of a Physics Front Topical Unit.


Topic: Electromagnetism and Electromagnets
Unit Title: Electromagnetic Induction

This tutorial gives beginning students a grounding in the physics underlying generators and motors.  Clear and concise illustrations help students differentiate the components of each device.  The author devotes careful attention to conductor coils and how they are used to cut through lines of force and strengthen a magnetic field.   Simple graphs depict the cycles of both AC and DC current waves.
