From '65-'93, Mustang speedometers were cable-driven mechanical instruments that worked on the eddy current principal-a magnet whirling around inside a shell attached to an indicator needle. The ...

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 ...

Eddy current testing (ECT) is a widely adopted non-destructive evaluation (NDE) method that leverages electromagnetic induction to detect and characterise defects in conductive materials. By inducing ...
