Imagine not having to pay your electricity bills because a gigantic magnet surrounding the Earth produced power. Well, Earth indeed has a magnet like this, which is its magnetic field. When the fiery ...

A wild idea has been proposed to generate electric power from Earth’s rotation with the help of magnetic fields. A new research has presented experimental evidence confirming a previously theorized ...

Scientists have created flexible composite material on the base of polymers and nanoparticles of cobalt ferrite, that is able to transform magnetic fields into electric tension. Such transformation ...

Researchers have demonstrated an innovative method to control magnetism in materials using an energy-efficient electric field. The discovery focuses on materials known as magnetoelectrics, which offer ...

Researchers have identified a potential mechanism that explains how turbulent plasma can produce the vast, ordered magnetic fields observed across the universe Cosmic magnetic fields are everywhere, ...

Fleeting electron-hole pairs are giving scientists a new window into optimizing light-emitting devices (LEDs). Using quantum ...

If you took introductory physics, you learned about the “fundamental forces.” It goes something like this: All interactions are the result of one or more of five basic forces: strong nuclear, weak ...

(Nanowerk News) In a scientific breakthrough, an international research team from Germany's Forschungszentrum Jülich and Korea's IBS Center for Quantum Nanoscience (QNS) developed a quantum sensor ...

Superconductors are among the most puzzling materials in physics. They conduct electricity with zero resistance, but only ...
