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 ...

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 ...

This one-way electric flow, known as rectification ... They carefully controlled the magnetic structure using external magnetic fields, which in turn manipulated the material's electronic behavior ...

Reader Jayant Bhalerao, a college physics instructor, found the story useful in class: “We will share it with our students, so that they can appreciate how ...

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.

The phenomenon can be tuned by adjusting either the magnetic field, the electric current, the applied gate voltage or the distance between the oscillators. Produces the best guess ...

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