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

I was going to take a break from “The Chronicles of GND.” But “Push Me, Pull Me” resulted in a surge of correspondence—much of it criticism that I had not included any diagrams of the various forms of ...

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, ...

Eddy current testing is a well-established method of nondestructive testing that is used to examine nonferrous/nonmagnetic materials such as condenser and heat exchanger tubes in power generation ...

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 ...
