Electricity & Magnetism

In 1752 Benjamin Franklin made a device he called Franklin's bells for detecting approaching lightning storms. He did this by placing two bells adjacent to each other with a metal ball suspended in between them. One bell was electrically...

The function of an 'earth wire' is to provide a low resistance path so that a high voltage current can drain off to the earth grounding. Clothes in a laundry dryer often build up a lot of annoying static...

An 'electroscope' is a scientific instrument that is used to detect the presence and magnitude of electric charge or 'static electricity' on a body. Static electricity or an electric charge is caused by friction between the surfaces of bodies,...

This science project will detect and demonstrate the presence of the unseen static electricity field that emanates from a CRT TV's picture tube.

The rule for static electricity is that different (opposite) charges attracts, while the same (equal) charges repel one another. Static electricity can be demonstrated in many ways. Make an amusing electro-static flower to show how similar charges repel one...

Did you know you can make silver foil balls dance about to the rhythm of a CD track….Well not exactly; you can however make the balls dance around on top of the CD disk with a science phenomenon called...

A 'Van de Graaff' generator is an electrostatic generator often found in school science classrooms. With this device, a high voltage electrical charge can be built up in its dome. Repel the strings from two teabags charged with a...

The rule for static electricity is that different (opposite) charges attracts, while the same (equal) charges repel one another. Static electricity can be demonstrated in strange ways as can be seen in the following scientific experiment.

The rule for static electricity is that different (opposite) charges attracts, while the same (equal) charges repel one another. A positive and a negative charge will hence attract one another, whereas two of the same charges will repel one...

Did you ever think it would be possible to bend water? It might sound very unlikely, but in fact this can be done quite easily by using the science of static electricity.
