S cientists have found that it’s possible to generate electric power from Earth’s rotation through its own magnetic field ...

A coil with an iron core is called an electromagnet. The iron core increases the coil’s magnetic field strength. A simple electromagnet is made by coiling wire around an iron nail. An iron core ...

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 ...

In these devices, variations in an electric current cause variations in the magnetic field produced by an electromagnet. This causes a cone to move, which creates pressure variations in the air ...

The ability to conduct heat is one of the most fundamental properties of matter, crucial for engineering applications.

What do rope winding and giant pasta shapes have to do with particle physics? The answer is a ... This new type of electromagnet has many benefits: it requires a much lower current, has a ...

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 ...
