My Adventures in Ferromagnetism

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.
