Thank you for that. I was thinking in terms of Newtons 1st law of motion in a perfect vacuum (and over eons of time) and didn't consider that light itself has inertia and would affect its angular momentum as its being radiated. But, isn't it still conceivable that even down to the last atom of the magnet, there's a mathematical improbability that the spin would be zero, considering entropy? Or maybe the opposite is true, that entropy was working toward bringing the very last atom down to the lowest energy state possible, essentially converting any remaining angular momentum into light so that it can achieve the lowest energy state possible. I could see it going both ways, maybe even being in an entangled state of both outcomes until an observation is made.
