One point I don't think I've ever had clarification on - a magnet is effectively demagnetised above the Curie temperature. If two magnets are allowed to fall together they are converting their potential energy into kinetic energy, 'falling' down each other's magnetic gradient.

Thanks! I figured that might be the case; presumably where the magnetic field contains ferrous materials or another magnetic object, the domains are aligned more strongly and more energy is needed for the transition (similar to a denser solid?)

Yep! Ferromagnetism is a bunch of atoms collaborating to have a common orientation, which the thermal energy overcomes as the temperature increases. Very much like a crystal.
