Inductance of inductor in large steady state magnetic field

AI Thread Summary
The inductance of an inductor is unaffected by a large steady-state magnetic field if it has a non-magnetic core, such as air. In contrast, a ferromagnetic core can experience saturation from a strong external magnetic field, which alters its inductance. When saturation occurs, the inductor behaves similarly to one with an air core, leading to a decrease in inductance. The presence of a high permeable core versus an air core significantly influences how the inductor responds to external magnetic fields. Thus, the inductance remains stable in air, while it may vary in ferromagnetic materials under strong magnetic influences.

So would the inductance of a inductor be effected if it was in a large steady state magnetic field. Say the inductor produces a field of about .01 Tesla and the large electromagnet produces a field of 1 Tesla or more.

How would a high permeable core vs a air core effect it?


Would it add to the inductance or would it decrease it or no effect?

If the inductor has a non-magnetic core (air) the inductance remains the same, irrespective of the presence of the external field.
On the contrary, a ferromagnetic core may saturate and the inductance would be different.
 
So basically in air, the inductance should stay roughly the same or the same. In a ferromagnetic core , if the external field is large enough, then it may saturate the core, causing the inductor to no longer have the same inductance. Since the core is saturated, I assume that the inductor may start to act more like that of a air core then. That seems like it would make sense.
 
Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'
So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
