A panel system comprises: (a) a rigid panel having a first surface, the first surface having a coating thereon, the coating comprising a binder and a particulate material selected from the group consisting of paramagnetic particles, superparamagnetic particles, ferromagnetic particles, ferrimagnetic particles, and mixtures thereof; and (b) a cover layer adjacent to and in contact with the first surface of the rigid panel. In an alternative embodiment, the coating can be disposed on the cover layer. In another alternative embodiment, the coating can be disposed on an intermediate fabric layer that is positioned between the rigid panel and the cover layer.
