When you break a bar magnet in half, it reforms north and south poles. The process repeats with additional breaks. Why, and how far "down" will I continue to get these magnetic poles?

I understand that magnetism is basically formed by the uniform up or down spin of electrons, ( I could be wrong about this. I'm not even close to an expert.) If I'm correct, why does breaking a magnet cause these electrons to re spin in the appropriate configuration? Also, if I break a magnet in half, and then again and again... at what point will I stop seeing opposite poles?

They don't re-spin. 

Think of the smallest "unit" of magnetism as pointing one direction. One direction it points will be "north", and the other is "south".

This is a fundamental aspect of magnets (di-poles). 

When you add a bunch of these units together facing the same direction, their strength becomes cumulative, and they make a "larger" magnet. 

So as you can see, when you break a magnet down, nothing needs to "spin", because the fundamental nature is they have a north and south pole all on their own.
