Re: Lenz's Law?



The demos of this that I have seen only send a single pulse of current thru
the coil, making the Lenz's Law explanation more beleivable.

Lenz's law says nothing about the flux *per se*. It relates to changing
flux, and AC is perfectly good for producing changing flux. The current in
the ring is quite evidently in such a direction as to force the ring toward
a region of less rapidly changing flux. If the single pulse demonstration
makes the explanation more believable then the explanation needs modifying,
not the demonstration.
