Flux & Physics: Explaining the Constancy of Flux

Click For Summary
The discussion centers on the constancy of magnetic flux in circuits when components like resistors are added. It highlights that while changing circuit elements affects current and flux, these changes do not occur instantaneously. The time factor is crucial, as the system requires time to adjust to new conditions. The reference to L/R time constant emphasizes the gradual response of the circuit. Understanding this concept is essential for grasping how circuits behave under varying conditions.

This is an excerpt from a high school physics textbook. I don't understand the possible reason behind this statement. If we change something in the circuit say for example add a resistor , the current and hence the flux should change. Then why/how is this statement true?

Correct, but not instantaneously: it takes time. https://www.electronics-tutorials.ws/inductor/lr-circuits.html is ##L/R##

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.
