Inductance of inductor in large steady state magnetic field

Click For Summary
SUMMARY

The inductance of an inductor is unaffected by external magnetic fields when using a non-magnetic core, such as air, even in the presence of a strong magnetic field of 1 Tesla. However, when a ferromagnetic core is used, the inductance can change significantly if the core saturates due to the external field. In saturation, the inductor behaves similarly to one with an air core, resulting in a reduced inductance. Therefore, the core material and its saturation point are critical factors in determining the inductance in varying magnetic environments.

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?
 
Physics news on Phys.org
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.
