What is a permanent magnet? Where does its permanencycome from? How does a magnet behave when forced tochange its "permanent" magnetization? What is therelationship between structure and ferromagneticproperties? What is hysteresis and what is it usefulfor? Does a ferromagnet blow-up when it gets to thethe critical point? (No) What happens to ferromagnetnear the critical point? Can one design an automaticalgorithm to find the critical point of aferromagnetic system? Can one demonstrate hysteresiswith... Mehr
