Maybe a stupid question, but I'm trying to get my brain around the concept of magnetism, specifically for static magnets, not electromagnets. I understand that the magnetic field is a result of all the moments in the atoms being aligned. The spin of the electrons around the atoms is the current so to speak. But I fail to see how this field transmits, is it some type of particle? Is there some form of medium needed? or is this some type of space time distortion like gravity? And how is it that a metal object will attract regardless of its orientation? Surely the random alignment of the atoms will result in a zero net force?
