Ferrites work that way: converting 'high' frequencies
to heat. Used as noise filters (eg EMI/FCC
Compliance) power levels are low, so heating is
minor. Used in high (rf) power environment, they
A related thought:
Different ferrites are compounded for different
freqs. Many will have low loss at 'coiling' freqs,
which can be a good thing, or a bad thing, depending
on the objective...
