Now he is using made-up words to describe it- what on earth is nanomagnetism?

I have no idea. But I can dream. I would love to see traditionally non-magnetic materials become magnetic. Imagine a tiny ceramic device at the bottom of a container, that converts heat into electricity. It could keep a beverage cool, while the energy is converted into stirring a drink. I've got lots of ideas.

Why do your ideas require the magnetic element to be ceramic?

In any case, there are already magnetic ceramic materials. Your fridge magnets are made of ferrite, an oxide of iron (that's a ceramic).

And there are devices that convert heat (or more accurately temperature differences) into electricity. Look up thermoelectrics. They're nothing but a peltier junction run backwards.

A thermocouple converts heat into electricity, or the reverse. I have ice chests that do that stuff quite well.
