You can test stir bar behaviour by filming through the side of a vial or using a magnetic material (nickel or iron granules) ...

And while this magnetic levitation motor does not break the laws of thermodynamics, ... (it’s spinning!) out of the least energy. It’s not magic, but it’s right on the edge, no? Report comment.

But as Alanna Mitchell shows in her new book, The Spinning Magnet, it wasn’t always that way. Indeed, as little—in geologic time, anyway—as 780,000 years ago, the poles reversed.

That leaves an extremely dense, rapidly spinning, highly magnetic stellar remnant surrounded by a shell of cast-off material. However, this material can eventually return to its point of origin, ...

Magnetic spinning tops are different. Once put into motion and left to itself, a spinning top will slow down after a few rotations and eventually come to a halt.

Magnetic levitation demonstrated using a Dremel tool spinning a magnet at 266 Hz. The rotor magnet is 7x7x7 mm 3 and the floater magnet is 6x6x6 mm 3.This video show the physics described in the ...

Nanoscale spinning magnetic droplets created Date: March 14, 2013 Source: North Carolina State University Summary: Researchers have successfully created a magnetic soliton -- a nano-sized ...

The environment around a black hole is, literally, a hot mess.That mess makes a little more sense to scientists now, thanks to a new computer simulation that shows how the spin of a black hole can ...

In this model, the coils take the place of the mirrors while the magnetic fields play the role of light spinning around a black hole. During their testing, the researchers discovered that the small, ...

Once a planet like Earth starts spinning and generating its own magnetic field, that magnetism tamps down turbulence. The scientists at Grenoble can now study how that happens inside the flowing ...
