A magnet falling down a copper tube is slowed by magnetic fields from eddy currents induced in the tube. A magnet falling down a glass tube is unaffected. Set up lab stands, each with a 3-finger clamp ...

From DIY levitation tricks to clever braking systems, these swirling paths of electrons keep finding new ways to surprise and inspire.

Lenz’s Law is one of those physics tricks that look like magic if you don’t understand what’s happening. [Seth Robinson] was inspired by the way eddy currents cause a cylindrical neodymium magnet to ...

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 ...

The description of an eddy current separator (ECS) sounds like the wrong answer to a science quiz: How can it use magnets to repel, rather than attract? And how can it affect nonmagnetic metals like ...

A nondestructive testing technology called eddy current array (ECA) is capable of driving numerous eddy current coils that are positioned next to one another in the same probe assembly. In the probe, ...

At some point during our primary school careers, most of us probably constructed a simple compass, often by floating a magnetized needle on a cork in a cup of water. The water in such a configuration ...

SANIKA: THE ORLANDO SCIENCE CENTER IS KNOWN FOR USING FUN TRICKS AND CRAFTS TO TEACH KIDS ALL ABOUT DIFFERENT PARTS OF SCIENCE, BUT THIS TIME, ALEX ALECCI IS PARTICIPATING IN THE FUN. SHELDON: -- ...
