>>86790Temperature is a measure of the kinetic energy of molecules or atoms. If you decrease the kinetic energy of the atoms in the metal, they will stop vibrating and bumping around so much, and will remain relatively settled in their states. However, if you increase the temperature of the metal, the atom's will gain kinetic energy, and their movements will become more and more erratic. They will be constantly jostled by their neighbors (i'm talking about physical contact here, like actually being bumped, not contact through the magnetic field). This bumping makes it so that even if a neighboring atom has spin up, and you still want to have spin up, you are being pushed around randomly and your spin is likewise going to be random. So you are sitting there randomly alternating between spin up and spin down. Now if you add up all of the individual spins of the atoms you will average out to around 0 and there will be no net magnetic field.
And thats how magnets work. At least, one type.
