1. The problem statement, all variables and given/known data My problem is trying to understand this graph and explain why it changes the way it does 2. Relevant equations e=change in ∅/change in time 3. The attempt at a solution I know that the magnetic field increases/decreases when the magnet is on the way into the coil and when it is on the way out/through. I also know that the velocity on the way out is bigger and that's why the red part is narrower and it reaches a bigger EMF. One thing I don't understand is what happens between the entry and exit? The magnet is accelerating downward because of gravity. Does that mean that the magnetic field is changing? The magnetic field is dependent on the velocity, right?
