Electric Motors

Illustration of an arm extended and energy cycling through the forearm. Energy continues out through the tips of the fingers. A wire intersects the hand, and an arrow indicates movement to the right. Caption: exerted on the conducting wire.

Part of the "A 3-D Demonstration" series. Explores the basic principles behind the operation of AC and DC motors. Explains how one or more fixed magnets, either permanent or electromagnetic, can cause linear movement or rotation of a current-carrying wire. A hand rule is developed to predict motor force. Motor torque is explained as a prelude to the practical design of a direct current motor. Specific modules include Motors and Magnets, Current and Magnet Interaction, Left-Hand Rule, Motor Force, Motor Torque, and DC Motors. Correlates to all National CTE Organizational Standards (including the provisions of the Perkins Act).
