Researchers have uncovered friction without contact—driven entirely by magnetic interactions. As two magnetic layers slide, their internal forces compete, causing constant rearrangements that ...

The film demonstrates an experiment using an apparatus to observe the behavior of electrons in a uniform magnetic field. It explains how electrons are accelerated by an electron gun and then deflected ...

In the air people breathe, the water on Earth, the stars in the sky and more, atoms are the building blocks that make up the ...

If you say that you’re “nuking” something, pretty much everyone will know that you mean you’re heating something in the microwave. It’s technically incorrect, of course, as the magnetron inside the ...

Historically, prior to 1820, electricity and magnetism were thought to be separate entities of nature. On April 21, 1820, ...

Researchers found friction can occur without contact, driven by magnetic dynamics, and does not always increase with load. The effect could enable controllable, wear-free technologies.

The late physicist Joseph Polchinski once said the existence of magnetic monopoles is "one of the safest bets that one can make about physics not yet seen." In its quest for these particles, which ...

Electrical conductivity experiments use four to eight tungsten wires, magnetic susceptibility experiments require a microloop of about ten turns of wire, and high-temperature experiments use eight ...

A major defense against everything space throws at us, Earth’s magnetic field may even protect the moon from damaging ...

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 ...
