There's a lot of tricky stuff you can do with magnets.


This is relevant to students who wonder what sort of job
they can get with a bachelor's degree.  If you know a little
bit of:
 ++ physics,
 ++ materials science,
 ++ finite-element modeling, and
 ++ mechanical engineering

you can get a job designing motors and actuators of all
kinds.  I know a guy who tried to retire but they kept
calling him back as a consultant at ever-increasing prices
because he knew how to do this stuff.

Contrast this with (say) just plain mechanical engineering.
