Inductance of inductor in large steady state magnetic field

[nemesiswes]

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.
