The inductance of a Coil!!! This topic is very poorly understood by so many.

An Inductor has Inductance.
The Inductance changes with the change in Magnetic Field.
The Inductance does not move to Zero if the Core is Saturated! There is still an Inductance present!

This is called Differential Inductance!

Some work I have done to show this is here: http://www.hyiq.org/Updates/Update?Name=Update%2017-12-13

Ok, who is voting False - Lets discuss why you think this is False...

Tinman,
If you see the coil as a whole (wired as one conductor ), then the coil never sees a changing field.
If you break the coil winding in the middle (2 sections), left and right, then you have the same effect as 2 coils , sure the BEMF will buck in the middle in the same way the rotor magnet field does.  I do not see any advantage on first view

Ah yes,but what if the inductor core is a toroid,where all the magnetic field remains within the toroid core it self.

Fields superimpose linearly.  So if you come up with an arrangement where you are changing one field relative to a wire that induces one way with another that induces in the opposite direction, the reduced net field change just reduces the induced EMF, and consequently the mechanical load reflected back to whatever is causing the relative motions.

To specifically answer your question:  The answer is no.  Portions of wire that are away from the changing field just act like lead wires.  You don't have to concern yourself with those until you deal with signals that change fast enough that those leads look electrically long.

But what if the core is a toroid?,where the magnetic field is suppose to remain within the toroid core it self. If two coils are wound on the toroid core,so as one coil is wound on 1/2 of the core,and the second is wound on the other 1/2 of the core,and a small gap left between each end of the winding's. A diametrically magnetised magnet is then spun near the core at the center of one of the coils. One side of the coil see's a north field,and the other side a south field(and no correcting here MH,we are using understood descriptions only). The center of the coil will see the the neutral zone of the field as well. Now what happens when we load both coils?,do we get a bucking field between the two coil end's,and is the BEMF directed back toward the rotating magnet,or dose it remain in the core?. If it dosnt remain within the core,then we have a south,and north field that meet in the middle of the coil winding-->which means a neutral field. So what will be acting against the rotating magnet?.

How would you create a low pressure zone in the atmosphere using coils.
