So, I performed an experiment where a bar magnet was allowed to drop through a solenoid connected to a voltmeter.
I have a graph of the voltage vs. time, and I have been asked to explain quantitatively the absolute value of the ratio of the maximum voltage to the minimum voltage. I have no idea how to do this.
We measured the length of the solenoid to be $0.11 \pm 0.005$ m and diameter was $0.03 \pm 0.005$ m, and the solenoid contained approximately $\text N = 3000 $ turns. We also have the length of the bar magnet as $0.15 \pm 0.005$ m.
I suspect Faraday's law will be involved in the calculations, as will gravity, but I'm not sure how to get there. I could calculate $\vec{A}$ which is constant because I have the dimensions of the solenoid, but I don't know the strength of the field, and I don't have a function for the graph.
How can I proceed?
