Question about Activating Solenoids that are facing each other

[JayAshby]

TL;DR

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?
