So. Heavy iron thing wants to fall to the ground, but magnet keeps it up against gravity… How can this happen seemingly against entropy? Without input of energy?

You could ask the same thing of gravity working against the magnet. Or electrons being held in place near an atom’s nucleus. If anything, these are examples of a stable equilibrium that entropy leads you to rather than work being exerted to go against the equilibrium. The iron going towards the magnet rather than the Earth’s centre of gravity just happens to be the path of least resistance. Going against this path is what requires energy and reversing entropy.
