I have several line saying it is not at least in the brain, and so it looks like simple electronics does not apply to the brain. The information i have from michael persinger is that a non linear pulse can overcome a weaker background static magnetic field. He has about 100 publications on this area and his team have a dedicated lab for 20 years in Canada which is part of Laurentian University that research this. Bear in mind the brains non linear pulse also have an underlying Gamma or alpha cycle phase in the signal.
there are other aspects to this problem that give magnetic field strength from another view. Lester ingber with Paul nunez (innovator in most of EEG) has recently released a series of complex papers on neocortical statistical mechanics of aggregated magnetic fields in cortex columns calculating these weak fields acting together can also overcome the earths static field.

Ahh, we're expected to think that the laws of physics cease to apply inside brains. Convenient for your theory.
of course not. But that they are more complex than electronics described here. Mechanical, chemical and EMF forces all interplay at once. Its easy to make the mistake of concentrating on one aspect and missing the rest. i.e. Several types of physics need integrated, which is not straightforward.
from the recent labwork from fluery, filming the dipole force it seems the pulse is more like a slowly building climax to an MHD spike. I had taken the term pulse from the original mechanisms for glial magnetic fields which are calcium ion waves. They are referred to as pulses or waves in those works to differentiate them from neuron spikes and save a lot of confusion amongst neuroscience, where spike almost always refers to a neuron.
It appears from the movies of fluery that a spike is more appropriate description for this force in the developing brain though. One hemisphere jerks suddenly after a slow buildup of pulsing. The mathematical description given by fleury is a boundary condition jump between quadrupole, and dipole states. My prediction is the quadrupole is linear and always present as an underlying pulse while the dipole then builds up an MDH spike in a push back reaction to the one which just occurred on the other hemisphere. That is both are occurring at the same time, rather than a transition. One problem here is i cant apply ingbers neocortical statistical mechanics of aggregated magnetic fields for a solution. At least not his neuron model. The immature neurons have not migrated and so are inactive.
There is an expert in biophysics interested in what this new labwork is telling us. will be hearing from him next week hopefully. The good news for myself is that i predicted the results of fleuries work independently. He is missing the mechanism, which is what i worked on, while myself, ingber, Pereira & Furlan were scratching our heads over how to produce or even approach the labwork.
Fleury sorted that out. After PZ myers slated him for not producing lab results. Fleury then innovated a new time-lapse microscopy technique, although they were already producing labwork leading up to that which myers was not aware of, or chose to ignore.
