discussion with teacher
I have collated as follows:
1) we need magnet to be of two colors ( red n blue) only. Grey between may give the students the wrong notion that zero emf between the peaks are due to zero magnetic flux.
2) number tagged to every electrons is too near to the rings. Need to space it away from the electrons and ring if possible. So that students can decide the direction of a electron flow and see electron returns when magnet exits.
