Feynman wouldn't tell |
In Feynman't lectures Vol. II, pg. 17-5 (Ch. The Laws of Induction) there is
a section called "A paradox" in which a thought experiment is presented. It
has to do with a coil sitting on an insolating plate violating the law of
conservation of angular momentum. The man does not resolve the paradox and
leaves it for the student to ponder about the answer. To make matters worse,
he ends the section with the claim: "...When you figure it out, you will
have discovered an important principle of electromagnetism."
I have not been able to find an answer. Can anyone help?

Why do you study the Vol. II
if the Vol. 1 contains the fundamentally False assumption
that disqualifies entire Feynman's works?

As I recall, the answer appears further on in the volume, maybe ch. 26 or so.
I remember that my guess was that the current has moving electrons which have
mass, so when the current is stopped the disk must turn very slightly.
