Magnetism has nothing to do with concentrating meteorite falls. I can see where one might make that inference. Meteorites are found in Antarctica because, in several places, the flowing ice gets thrust up hill over a mountain ridge like a push-up popcicle. There the ice is ablated/scoured away by the wind. This leaves anything that has fallen into the ice left, or churned up by the ice lying on the surface. Meteorites and other rocks lie atop of the ice formation they were formerly buried in. Against the white background they are easier for researchers to find. I say this to make the point that not everything on the ice is a meteorite. More meteorites may be"found" there but there is no evidence that more meteorites "fall" there.
