Understanding the Fundamentals of Eddy Currents: Explained Simply

[Pseudo Epsilon]

hi all. I understand wikipaedias explination of eddy currents but could someone please explain more fundamentaly how they work. Thanks in advance :)

The Wikipedia Explanation seems pretty good. What are you not understanding?

 

[Pseudo Epsilon]

could you explain how in brakes they cause energy loss at such a high rate?

and explain it in qed possibly.

The simplest way of thinking about them is to consider that a wheel that is braking is cconfigured as an electrical generator. Then imagine a short circuit across that generator and the eddy currents flow through that short circuit. The braking is then caused by the mechanical load presented by a short circuited generator.

It does not look like a generator,, because in a normal genera to we want to use the electrical supply externally.

thanks, i misunderstood first time i read the wiki.
