# At what point the process of breaking a magnet stop?

If I break a magnet, I get two magnets. Now I could repeat this with one the two halves. If I keep going, eventually the magnet will be smaller than the size of an atom, so, one of two things should happen before reaching that point:

1. I separate the two poles
2. I cannot break the magnet anymore

I know 1. is impossible, since we cannot separate the two poles, so I am guessing the process need to stop at some point. At what point will I be unable to break my magnet, and why?
