Question

This is a question from my lab report: "Since magnetic flux is a function of the magnet's B field and the surface area of the solenoid, what variable determines the magnitude of the induced voltage and current and how does this help explain the differences in the positive and negative induced voltage peaks as the magnet drops through the solenoid?" I don't understand this question that well, but I'm assuming the variable that determines induces V and I is the change of time. I would really appreciate a explanation, thanks much!

Explanation / Answer

relative motion and turns of the coil determines the emf. when flux is increasing positive and when decreasing negative voltage.
