Note that the B-field is said to be confined to a concentric circle
with radius LESS than that of the loop.
Note also that the B field is said to be uniform.
Let's ignore the fact that these two are mutually exclusive
MY question is: IF the confined B field expands and contracts while still
being always INSIDE the loop, will an emf be induced.
And I will SWEAR that I have seen several references to the
quantum limit of magnetic field density, expressed in terms of the usual
gang of fundamental constants. Doesn't this mean that the 'nonexistant'
weber lines are discrete lines???
I am asking these previous questions also, with the restrictions and
variations stated above.
