What is a permanent magnet? Where does its permanency§come from? How does a magnet behave when forced to§change its "permanent" magnetization? What is the§relationship between structure and ferromagnetic§properties? What is hysteresis and what is it useful§for? Does a ferromagnet blow-up when it gets to the§the critical point? (No) What happens to ferromagnet§near the critical point? Can one design an automatic§algorithm to find the critical point of a§ferromagnetic system? Can one demonstrate hysteresis§with purely mechanical means? Can one use theory to§bridge between two seemingly conflicting experimental§results? Can one build a physically interpretable§model based on the Preisach-Everett model of§ferromagnetism? If you find these questions§interesting you can find them and many more §discussed inside.
