Again: Rotating magnetic field

Hi
I have read the thread " Is the magnetic field really moving? "
Very instructive and useful for me as, exactly in the very
same period, I was doing some thinking over the same
subject and some experiments as well.
Yet, I missed the thread at that time, being too busy.
Here I would like just to make a comment:
it is easier to consider a non-circular magnet in rotation
to get a quick answer to the question!
Yes, the magnetic field does move and/or rotate with
the magnet.
Consider for example a square cross-section magnetic bar
and you can see easily that if the corner of the field rotates
then the middle area has to do the same thing ( no matter
if it is a perfectly round area or not ).
Of course , the question posted in the thread was a bit
more restrictive than the one in the title of the thread ( which
was of more interest for me).
Best regards, LL
.
