Torsion cycles as non-local magnetic sources in non-orientable spaces

Abstract
Non-orientable spaces can appear to carry net magnetic charge, even in the absence of magnetic sources. It is shown that this effect can be understood as a physical manifestation of the existence of torsion cycles of codimension one in the homology of space.
