AirPod Pro's case sticking to metal shelf-any deleterious effects?

When I put my AirPod Pro 2 case on the metal riser shelf for my Mac mini's display, the magnets in the case hang on to the shelf, even underneath the shelf (which is kinda cool, if I want to hide them, but I don't need to). I'm wondering what effect this might have on the case or the AirPods. Will this do anything to the stored power in the case or AirPods, such as draining either or both, or is this just benign?
