Although, I am no expert in the field of magnetism, if you'll pardon the pun...the diagram submitted by @poynty appears to indicate a torque/action/energy/ potential within the 'bloch wall.'

I could be wrong like Bill tho...just tossing things out there, you just never know, it may be a ball someone can run with.

Here is some data for anyone interested.  It is input and output measurements on the 3 single filer coil pairs run in parallel to the dump cap with various loads.  All measurements were taken with the same DMM.

In the real macroscopic world, where EE's design and make things, and theorists take a back seat, the term, bloch wall, is readily accepted as referring to the "null magnetic region" in a magnet where N + S vectors are equal, and cancel out. Also often referred to as the magnet's neutral region.

This is a misnomer all too many believe. There is only one macroscopic vector inside a standard magnet.

The magnetic field measured outside a magnet in the center may appear weak compared to the end-pole locations, but this is not because of any vector cancellation or equality. This area does not constitute a "Bloch Wall Region", despite any general misuse of the term.

It would be a true shame if "real-world" EE's contributed to this misnomer. But, as most may not be well trained in magnetics, this is a possibility. Don't take this the wrong way, but I would expect (and hope) that anyone working in magnetics as a profession, or as a serious researcher using magnets and ferromagnetic materials, would be better informed.

On my site I describe the bloch wall as the magnet neutral zone to make this distinction.

Call it a "neutral zone" if you wish, but it should not be called a "Bloch Wall". This only perpetuates the misnomer, and facilitates a misunderstanding of the magnetic field in and around a magnet.

It's quantum mechanics, the magnetic neutral region does not exert a net outside force to let's say a piece of metal, but the magnetic domains re-align there.
The process of "pumping" the Bloch wall (or however you wanna call it) is assumed to create negative entropy however. Example : "Kromrey Converter"

To me it seems there is a little twist in there that needs to be explored by someone with more experience and instrumentation than I currently possess.

Thanks for acknowledging that aspect...it may possibly lead somewhere.
