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

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 ...

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

Christopher Chyba held a hollow, dark cylinder made of manganese, zinc, and iron in his Princeton lab, looking skeptically at ...

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

Just hours after touching down on the surface of the moon on March 2nd aboard Firefly Aerospace's Blue Ghost 1 lander, the ...

Researchers show that Cartan's First Structure Equation, which relates to edge and screw dislocations in crystal lattices, can be recast in the same form as a basic mathematical formula that governs ...

With today’s data rates of only a few hundred megabytes per second, access to digital information remains relatively slow.

Light is closely integrated with our intellectual, philosophical and scientific discourse. The exact nature of light has remained a mystery since we stepped on earth. Newton postulated the corpuscular ...

The iron-cobalt alloy is widely used due to its strong magnetic properties. However, there is a limit to how much their ...

How a tokamak works: The electric field induced by a transformer drives a current (big red arrows) through the plasma column. This generates a poloidal magnetic field that bends the plasma current ...
