A magnet will encounter no electromagnetic braking force while inside a superconducting tube, predict physicists in Brazil. This is exactly the opposite of what occurs in a popular classroom ...

Demonstrates how electricity can be produced from magnets through various experiments. It explains that electric currents can create magnetic effects, forming electromagnets that only work while ...

A magnet sliding down a copper ramp is slowed by magnetic fields from eddy currents induced in the tube. A magnet sliding down a Plexiglas ramp is unaffected. A magnet sliding down a brass ramp goes ...

If you drop strong magnets onto a plate of copper, something remarkable happens: the magnets slow down before hitting the surface and appear to levitate slightly, like the copper is another magnet, ...

The reason for copper's unique properties comes down to the configuration of its electrons. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Wires ...
