A baffle may conform to and be magnetically coupled to a body having a ferromagnetic component in proximity to the baffle. The baffle includes a first layer of a flexible thermally expansible baffle material which expands when subjected to an elevated temperature, and a second layer of a flexible magnetic material. The baffle may thereby be flexed to conform to an irregular or curved surface. In addition, the baffle may be preformed to provide an irregular or arcuate portion to conform to the body on which it is placed. The magnetic attachment facilitates attachment and removal without the need to provide holes in the body, and upon heating and expansion of the baffle, the baffle material expands to fill cavities and adhere to the inside wall surface of the body on which it is received.
