I don't think it is magnetism alone and I'll tell you why, the fox doesn't always orient north. If orienting to magnetic north increased his success rate b/c the fox could feel/sense something differently pointed straight north it would orient north when hunting under the snow.
The fox obviously doesn't know "north"/"South" is the key, so I doubt it is the key to success. I think something else is at play.
