Are inductors so powerful?

[physior]

hello!

are inductors so powerful that the magnetic field generated in their coils to be strong enough to resist the electron movement inside their wire?

I find that hard to accept

any hint?

thanks!

I'm not quite sure what you're asking. Are you asking if inductors really experience a counter EMF that opposes a change in the current flowing through them? If so, then yes, they absolutely do.

I am asking if that opposition to the power source that inductors, not "experience" as you say, but CREATE, stems from the creation of a magnetic field due to their coils

I am actually asking, if that magnetic field is strong enough to penetrate the metallic wires and inhibit the flow of the electrons within inductor's wires

with the same principle, if I place a magnet properly (ie. with the appropriate direction), near a wire where a current flows, I will inhibit it!

I find that strange, because I experimented with some inductors and their magnetic field was very weak and I wonder how can this magnetic field inhibit the flow of electrons inside the wires

Yes, the coil creates the magnetic field which inhibits the change in current.

Any magnetic field will penetrate the conductor, so raw strength has little to do with this. It's more about the rate of change and the number of turns in the coil.

No, you won't. A magnetic field only creates an EMF when it is changing in strength. A static magnetic field has no effect on the current.

Not sure what to tell you. That's just the way it works. If you do the math it will be obvious.

I can say that inductors do have the ability to generate strong magnetic fields, which can create a resistance to electron movement inside their wire. However, the strength of the magnetic field is dependent on various factors such as the number of turns in the coil, the material of the core, and the current passing through the coil. So while inductors can be powerful, their strength is not unlimited and can be controlled by adjusting these factors. It is also important to note that inductors are just one component of a larger circuit and their power alone cannot be determined without considering the entire circuit. I suggest further research and experimentation to fully understand the capabilities and limitations of inductors.
