A wild idea has been proposed to generate electric power from Earth’s rotation with the help of magnetic fields. A new ...

A trio of physicists from Princeton University, CIT's Jet Propulsion Laboratory and Spectral Sensor Solutions, all in the U.S ...

Scientists know well how conventional materials conduct heat. However, things are not as straightforward under extreme ...

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 ...

Experiments suggest an unusual magnetic material could help harness energy from Earth’s rotation. But not everyone is ...

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 ...

They applied an electric field as an added source of interference, which enhanced the visibility of the domains by up to 90%. Previous attempts used a combination of magnetic and electric fields ...

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 ...

If these metals have not been turned into a permanent magnet they will still be attracted to a magnet if placed within a magnetic field. In this situation they act as a magnet - but only whilst in ...

The ability to conduct heat is one of the most fundamental properties of matter, crucial for engineering applications. Scientists know well how conventional materials, such as metals and insulators, ...
