For more than a century, engineers have chased new ways to turn the planet’s natural motions into usable power, from tides to ...

I have talked about the course I teach for elementary education majors before (videos for education majors, Spring Course reflections). Anyway, the nature of the course is that students collect ...

In a radical move, researchers have made the most significant stride yet toward unlocking almost inexhaustible sources of green power. This is from OpenStar Technologies, a New Zealand company that ...

Eddy current braking systems utilise the generation of induced currents within a conductor, created by changes in magnetic fields, to provide smooth and contactless deceleration in various transport ...

There is a novel sort of bicycle dynamo that holds a strong magnet loosely in a little box next to the wheel rim. Once the wheel starts to rotate, the magnet’s field starts to interact with the ...

An electric current can be induced in in a coil of wire by moving a magnet in and out of the coil. AC generators are used in the generation of electricity and in their simplest form consist of a coil ...
