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 'Reflections at the source point of a transmission line'

I was using the Smith chart to determine the input impedance of a transmission line that has a reflection from the load. One can do this if one knows the characteristic impedance Zo, the degree of mismatch of the load ZL and the length of the transmission line in wavelengths. However, my question is: Consider the input impedance of a wave which appears back at the source after reflection from the load and has traveled for some fraction of a wavelength. The impedance of this wave as it...
