Hello.
Let's take a picture that live and neutral wires wrap around ferrite core several times for common-mode noise filtering.
As fas as I know high frequency noise is filtered by ferrite core in inductive way, which means noise is stored in form of magnetic field such as normal inductor.
But ultimate aim is not to store noise but eliminate it.
Eventually, where does the noise trapped within ferrite core go? Is it reflected back to original noise source or released to wires for a relatively long time thus noise "amplitude" falls acceptable range?
