Re: Lenz's Law

 In which case it is the cutting, not the resistance, that affects the
current.
 In any event, I meant to say that "resistance in the current loop does
not affect the derivative of the current in the straight wire" (which is
given).  The EMF applied to the loop is proportional to the derivative
of the current in the straight wire, the resistance of the loop affects
the amount of current that responds to the applied EMF.

                                                        Jack

not up.
