Increasing the number of turns on the coil of wire The image below illustrates a simple experiment to demonstrate electromagnetic induction. The direction of a motor effect force can be found ...

Researchers at ETH Zurich have managed to make sound waves travel only in one direction. In the future, this method could also be used in technical applications with electromagnetic waves.

It’s an electromagnet pendulum analog circuit. Whether you’re building it, or just studying the schematics, this is a fun way to brush up on the non-digital side of the craft. The pendulum is ...

This is mechanical energy in action. The mechanical energy is caused by the attractive force of the electromagnet. Now imagine a circle of electromagnets that you could turn on and off one after ...

It is also grade school science to show that neither an electromagnet nor a permanent magnet will pick up nonferrous items like copper or aluminum. While technically not an electromagnet ...
