Hold your copper pipe in a vertical position. Insert your magnets into the top opening of the pipe and let them go. They should drop slowly through the pipe as if they were going in slow motion. By ...

Eddy currents are not just textbook curiosities; they are the hidden loops that appear whenever metal meets a changing magnetic field. From DIY levitation tricks to clever braking systems, these ...

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 ...

John Hansen, Managing Director/CEO of Ether NDE Ltd, talks to AZoM about Eddy Current Testing. What is an Eddy Current NDT? Eddy Current Testing is one of the many Non-destructive Testing (NDT) ...

Eddy currents are specialized electric fields that are generated in the presence of a magnetic field and are often seen as a secondary field. An Eddy current can be produced by both electromagnets and ...
