Question about Activating Solenoids that are facing each other

Click For Summary
SUMMARY

The discussion centers on the effects of activating two solenoids facing each other, specifically regarding their electrical input when experiencing magnetic repulsion. It is established that the configuration creates a transformer-like scenario, where the primary and secondary windings interact. The coupling coefficient between the solenoids affects the efficiency of this interaction, and the electrical input will differ significantly compared to a single solenoid without competing magnetic fields. The connection method of the windings, whether in series or parallel, also plays a crucial role in determining the electrical characteristics.

PREREQUISITES
  • Understanding of solenoid operation and magnetic fields
  • Basic knowledge of transformer principles and coupling coefficients
  • Familiarity with electrical circuit configurations (series and parallel)
  • Experience with electromagnetic theory
NEXT STEPS
  • Research solenoid design and magnetic field interactions
  • Study transformer theory, focusing on coupling coefficients
  • Explore the effects of series vs. parallel connections in electrical circuits
  • Investigate practical applications of solenoids in electromagnetic systems
USEFUL FOR

Electronics engineers, hobbyists working with solenoids, and students studying electromagnetic theory will benefit from this discussion.

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?
