The experimental results show the decreasing
electron temperature along the expansion, following a near perfect adiabatic expansion of an electron gas when electric fields are removed from the system.
Not exact matches
For this to work, the wire's surface must be extremely clean, allowing
electrons to move freely and spread
along the wire to create a uniform
temperature.
And that if you heat a magnet up enough, then you have no magnet at all: High
temperatures randomly jumble all the bits of magnetic material (ultimately orientations of spinning
electrons) that had aligned themselves
along the north - to - south - pole axis.
