The pendulum is a neodymium magnet on the head of a bolt, dangling on a one foot aluminium chain. Below, a Hall Effect sensor rests atop an electromagnet — 1″ in diameter, with 6/8″ wire ...

There's a magnet in a secure room in central Tokyo. It's an electromagnet, the kind that generates a magnetic field when ...

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 ...

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 ...

Experiments had already shown that the movement of electrical charges appeared to produce magnetic fields ... so-called electromagnetic waves, which he proved were travelling at the speed of ...

This movement creates a field surrounding the antenna that has both an electric and magnetic component. Electromagnetic radiation is carried by photons, massless particles that travel at the speed ...

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 ...
