This persnickety number determines the strength of magnetic fields. It figures in everything from motors and generators to audio speakers. Oh, and without it we’d live in eternal darkness.

There are two types of stud finders: magnetic and electric, each with pros and cons. Magnetic stud finders are cheaper, but ...

The electrical manipulation of magnetism and magnetic properties has been achieved across a number of different material systems. For example, applying an electric field to a ferromagnetic material ...

It is anticipated that within just a few decades, the surging volume of digital data will constitute one of the world's ...

Transistors, the building blocks of modern electronics, are typically made of silicon. Because it's a semiconductor, this material can control the flow of electricity in a circuit. But silicon has ...

Scientists have managed to use electrical fields to control the magnetic oscillations of certain ferrous materials. This has opened up huge potential for computer technology applications, as data is ...

From Franklin’s kite in a storm to Einstein’s special relativity to QED - electromagnetism has gone on to explain everything ...

Magnetism is due to the magnetic fields around magnets. The fields can be investigated by looking at the effects of the forces they exert on other magnets and magnetic materials. Electrical quantities ...
