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

PC-board layout sets the functional, electromagnetic interference (EMI), and thermal behavior of a power supply. Good layout from first prototyping on actually saves significant resources in EMI ...

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 ...

The ECL202 eddy-current displacement/ position sensor features improved thermal stability, immunity to electromagnetic interference (EMI), linearity, and resolution. FPGA technology lets the sensor ...

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 ...

The second part of this feature on controlling EMI in power supply boards explores the challenges posed by external switch drive signals and the effectiveness of shielding techniques. Methods to ...
