black powder coming out from the tunze magnet

is this normal to happen ?

does it mean the coating is coming out ?

It looks like a good wipe down should take care of that.

I have seen that before, the black color of the resin comes from an added carbon powder so some of this can rub off on the surface, typically if the resin is failing it cracks.
