[Seth Robinson] was inspired by the way eddy currents cause a cylindrical neodymium magnet to levitate inside a rotating copper tube, so he cast a spherical copper cage to levitate a magnetic sphere.

(Courtesy: R Bjørk) Magnetic levitation is already employed in systems such as ... In the TU-Denmark team’s experiments, this magnet was spherical, 19 mm in diameter and made from neodymium-iron-boron ...

Magnetic levitation demonstrated using a Dremel tool spinning a magnet at 266 Hz. The rotor magnet is 7x7x7 mm3 and the floater magnet is 6x6x6 mm3. This video show the physics described in the ...

A new study published in Applied Physics Letters highlights how researchers have made huge breakthroughs in magnetic levitation, the use of magnets to cause items to levitate in air for extended ...

On the other hand, they don't show up in slow-speed transit services all that often, since the energy used to levitate a ... too – a neodymium-enhanced magnet loses less than 5% of its magnetism ...

Gravity basically doesn’t factor into a new style of rotation-based magnetic levitation being developed. This spin-stabilized levitation uses a rotating magnet to steady the levitating magnet ...

In a first-of-its-kind test, scientists used a levitated magnet to search for dark matter, the unidentified substance believed to be present throughout the cosmos. If dark matter is made up of ...

A strong type of magnet used in many new commercial products can interfere with pacemakers and implanted heart devices with deadly consequences. Close contact - within about 3cm - with a neodymium ...

The element bismuth can "float" between magnets due to magnetic levitation. What's the science behind this phenomenon? When you purchase through links on our site, we may earn an affiliate commission.
