Seeing is believing. In these animations, we show you what electricity and magnetism might look like if they weren't invisible.
Capacitors can store electrical energy and discharge it quickly, powering things like flash bulbs and starter motors.
DC motors make things like appliances and power tools work by converting electrical energy to mechanical energy. Find out how.
EMF, or electromotive force, refers to the voltage created by a battery or by a changing magnetic field. Counter EMF, also called Back EMF, is a related phenomenon that we will illustrate in this animation.
Conventional automobiles burn gasoline in an internal combustion engine and convert that energy into motion. But first a spark is needed to ignite the fuel mixture. This animation shows how a 12-volt battery generates the high voltage required to create such a discharge.
You use it to pop popcorn and heat up soup. Now learn what happens behind the microwave door.
Watch how radio waves and strong magnets combine to create pictures of the inside of our bodies.
Watch how Hans Christian Oersted discovered quite by accident in 1820 that electricity and magnetism are related.
Take a journey into the center of a one of our magnets to watch an experiment on graphene, one of many things scientists study at the MagLab.
Used originally to charge particles in atomic accelerators, Van de Graaff generators are now used mostly to educate students about electrostatics. See how they generate the static electricity that can make your hair stand on end.
Learn to use your own two hands to understand the relationship between electricity and magnetism.
