Maximum magnetic force produced by ferrous material

AI Thread Summary
In a scenario where a block of iron with mass "m" is subjected to an infinitely strong magnetic field "B," the force exerted by the iron block on an immovable wooden interface is questioned. The discussion suggests that the force could be infinite due to the nature of the magnetic field's strength. Participants explore the implications of this theoretical situation, considering the limits of physical laws. The connection to previous discussions on magnetic forces highlights the complexities involved in such extreme conditions. Ultimately, the conversation emphasizes the challenges of calculating forces in hypothetical scenarios involving infinite variables.

Lets say you have a block of iron with a mass "m" exposed to an infinitely strong magnetic field "B." If there was a strong wooden interface preventing this iron block from moving towards the magnetic field source, how can you calculate the force the iron block would exert on the wooden board?

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.
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...
