One thing I forgot to clarify (I assumed, which is bad, bad, bad), is that at the atomic level, temperature is actually vibrations in the atoms, and is directly proportional to (measured by) KE (kinetic energy). Now, when matter goes from a solid, to a liquid, to a gas, what is happening is that the KE of the atoms exceeds the inter-atomic electromagnetic attraction that exists. Also, the entropy (disorganization) of the atomic structure increases as the temperature increases. It is the structured alignment of the atoms, and the orientation of the electron spin in a crystal that produces magnetism. When you heat it up, the entropy increases, so the orientation of the electrons gets all "jumbled" up, so to speak.
Same thing happens when you de-magnetize something. you are "un-aligning" the orientation of the atomic structure and electron spin in the material.
If you want to "supercharge" a Fe based magnet, you can do it with super cooling the magnet as well. All based upon electron spin and crystalline composition of the material.
Everyone snoozing yet? LOL

Today's Featured Article - The Rescue of a Fordson F - by Anthony West. Introduction I live in the UK and have for many years restored Fordson tractors (in the main model N's). I have also restored and shown model F's, E 27N's, Field Marshall Series 2, David Brown Cropmasters and the old rey Fergeson T 20. At one time I had seven restored examples which were shown and used in ploughing matches. As most restorers, I have a number of war stories I can relate on a range of topics that may help other like minded and interested people. Perhaps my first p
