Watch & Play

Watch & Play
See the science at play in these electrifying demonstrations and animations that illuminate the invisible electromagnetic forces. Or have your own fun with puzzles, games and a collection of interactive tutorials.

Interactive Tutorials
These demonstrations about laws and tools associated with electricity and magnetism allow you to adjust variables at and to visualize invisible forces — which makes them almost better than the real thing.

See-Thru Science
Seeing is believing. In these animations, we show you what electricity and magnetism might look like if they weren't invisible.

Game & Quizzes
Learn about electricity and magnetism — and have some fun while you're at it!

Science Demos
How do Maglev trains work? What are comets made of? How do bugs walk on water? This section demonstrates these and other concepts related to magnetism, electricity and other areas of science.

Current Flow

This tutorial illustrates the flow of electricity through a circuit and how that flow is impacted by resistors in the circuit.

Instructions

Take a look at the illustration of a battery, looped with a wire coil and a simple motor on parallel circuits. The yellow dots are electrons representing the flow of electricity.
Observe the readings on the flow meters, which show current in amps.
See how the flow is affected by the resistance from the wire coil and the motor. The coil offers more resistance than the motor, so you’ll see the difference in readings on the flow meters.
Use the slider to adjust the flow rate and see how it affects the meters.

Note that the flow measured for the motor and coil added together always matches the total current flowing through the circuit, seen on the meter to the right of the battery.
