Abstract: A drape element includes a sheet of flexible, non-magnetic material having opposed first and second longitudinal sheet edges, a longitudinal centerline toward which is defined an inward direction and away from which is defined an outward direction, and a first longitudinal pocket disposed proximate the first longitudinal sheet edge. A first straight magnetic wire is disposed in the longitudinal direction within an inward longitudinal portion of the first longitudinal pocket, and a first alternating sequence of magnets and non-magnetic spacers is disposed within an outward longitudinal portion of the first longitudinal pocket. Each of the magnets has opposed first and second magnetic poles, with a respective first magnetic pole of each of the magnets being disposed in contact with the first straight magnetic wire.
