B Understanding magnetic flux change during the falling of magnet

AI Thread Summary
Dropping a neodymium magnet into an electromagnetic coil induces voltage due to changes in magnetic flux. The discussion revolves around whether the change in induced EMF is a result of alterations in magnetic flux density or cross-sectional area during the magnet's fall. Participants explore methods to calculate these values without relying on experimental results, emphasizing the importance of understanding electromagnetic principles. The conversation references advanced physics concepts, suggesting a foundational knowledge in the subject is beneficial for deeper comprehension. Understanding these factors is crucial for accurately predicting induced EMF in similar scenarios.

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.

Thread 'Inducing EMF Through a Coil: Understanding Flux'

Thank you for reading my post. I can understand why a change in magnetic flux through a conducting surface would induce an emf, but how does this work when inducing an emf through a coil? How does the flux through the empty space between the wires have an effect on the electrons in the wire itself? In the image below is a coil with a magnetic field going through the space between the wires but not necessarily through the wires themselves. Thank you.

Thread 'Griffith, Electrodynamics, 4th Edition, Example 4.8. (Second part)'

I am reading the Griffith, Electrodynamics book, 4th edition, Example 4.8. I want to understand some issues more correctly. It's a little bit difficult to understand now. > Example 4.8. Suppose the entire region below the plane ##z=0## in Fig. 4.28 is filled with uniform linear dielectric material of susceptibility ##\chi_e##. Calculate the force on a point charge ##q## situated a distance ##d## above the origin. In the page 196, in the first paragraph, the author argues as follows ...
