SUMMARY

The discussion centers on the phenomenon of electromagnetic induction when a neodymium magnet is dropped into an electromagnetic coil. It confirms that the induced electromotive force (EMF) is a result of changes in magnetic flux density as the magnet falls, rather than changes in the cross-sectional area of the coil. Participants emphasize the importance of Faraday's Law of Induction for calculating induced EMF, which relates to the rate of change of magnetic flux through the coil. The discussion also references specific posts for deeper insights into the calculations involved.

TL;DR
What's the factor which induce EMF in case of falling magnet into the coil
If I drop the magnet into the electromagnetic coil, is magnetic flux density changed or cross sectional area changed during its falling? Actually I dropped a neodymium magnet into the coil and there was the voltage induced but I don't know what's the factor that induce the EMF in this case. Also if there is change of magnetic flux density or cross sectional area, how can I calculate those value without using experimental result I mean the induced EMF value.
