I Question about Activating Solenoids that are facing each other

AI Thread Summary
When two solenoids face each other with like poles, they experience magnetic repulsion, which affects their magnetic fields. This interaction leads to a decrease in magnetic field strength and alters the electrical input of each solenoid compared to a single solenoid without competing fields. The setup essentially creates a transformer effect, where the coupling coefficient is not ideal, impacting efficiency. The electrical input will vary significantly based on whether the solenoids are connected in series or parallel. Understanding these dynamics is crucial for optimizing solenoid performance in such configurations.

TL;DR Summary
Would activating solenoids that are facing each other affect the current input since the magnetic fields would repel each other?
In this situation I would have two solenoids facing each other, such that both ends are north for example, and when activated they are actively experiencing repulsion, I know that the magnetic field of both would decrease in strength, but would there be any affect on the electrical input of each solenoid? Specifically, would the electrical input be different if there was only a single solenoid with no competing magnetic field facing it?

Yes, it will be very different.
You have made a transformer, and have then connected the primary and secondary.

The transformer will not be perfect because the coupling coefficient is not high.

It will depend on how you connect the two windings.
Are they in series or parallel?

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 '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...
