Hi.
So I have a loop of wire parallel to Earth. I drop a magnet through
the loop. The magnet is lined up with N on top and S on bottom (so S
goes through the loop first).
If I were to qualitatively graph the flux vs time, and current vs time
I'd get (would I get?):
Part 1: S is far away to S / N magnet bisect the loop.
Flux goes from zero (or really really small) to a maximum (when S pole
is in center of loop) and then back to zero when the magnet is
by loop (weakest part of magnetic field).
