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 ...

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 ...

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 ...

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 ...

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 ...
