According to scientists, this ambipolar electric field is thought to be just as crucial to Earth as both gravity and ...

When an electric current passes through a metal wire, a magnetic field forms around that wire (see diagram at right). Likewise, a wire passing through a magnetic field creates an electric current ...

It looked still to you before because you were moving with it. We have this same problem with electric and magnetic fields. Depending on your reference frame, what appears to be a magnetic force ...

The aim of this module is to teach you the basic laws of electric and magnetic fields, their application to elementary problems involving steady and time changing fields and currents, and give you an ...

At a cost not far above £10 ($13.70), this was an impulse purchase driven by curiosity; these devices claim to measure both magnetic and electric fields, but what do they really measure?

With today’s data rates of only a few hundred megabytes per second, access to digital information remains relatively slow. Initial experiments have already shown a promising new strategy: Magnetic ...

When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet. The field inside a solenoid is strong and uniform. The small magnetic field caused by ...
