Learners compare electromagnetic quantities with the voltage, current, and resistance quantities of an electrical circuit. A brief quiz completes the object.

Learners examine how an electromagnet is formed. Animated illustrations show current running through a coil wrapped around an iron core.

In this animated activity, learners examine how a voltage is induced into a conductor when the conductor cuts across magnetic flux lines. They also view the four factors that determine how much voltage is generated. A brief quiz completes the learning object.
