I realised that this book was not in the library and it needs to be.
Regardless of whether you accept tha claim that Howard et al. Are the fathers of modern spintronics or not , or that he was a neighbour to Ed Leedskalnin this work provides important methodological information for a modern approach to magnetic behaviour and is immediately more c oncise than Ken Wheelers verbose but still vital modern approach.
The Ferrocell and the ferro fluid do not figure in this book and do important cross referencing need to be done, but then I have not seen any other basic introduction that relies on the hall sensor technology. . This methodology alone is vital to understanding magnetic behaviour and developing magnetic theory. . You will also find validation of Eds two magnetic spin currents in a copper wire attached to a battery , pictured prominent,y in this work .
I am NOT a particle theorist. I am a dynamic rotational aether theorist from which I attempt to depict and derive fractally distributed regional rotation behaviour. . Thus patterns of these behaviours represent rotational, periodic torsional and pendular motion behavious , that is vibrational and oscillatory behaviours of all kind. The simplest models of what I conceive are trochoidal dynamic surfaces whose 2dimensio al plane Intersections will look like fractal Trochoids, similar to those found at Fractalforums.com and Fractalforums.org.
Non of what I propose is conceptually easy , and I too am drawn to use common references despite them bei g misleading. . But I have presented many lines of interest and interpretation to disabuse the reader of over simplifying magnetic behaviour.
I am not an expert, just convicted as Ed was that magnetic behaviour is foundational, primitive and dynamically and perpetually rotational even if in dynamic static or motional equi.ibrium.
Ed, following Gilbert and other European philosophers proposed a dynamic partic,LE explanation or depiction of magnetic source. All particle physicists including Johnson do the same. . Thus monopoles become the fundamental building blocks. However I propose as did Boscovich rotational dynamics in an otherwise continuous medium. Thus vortices become the fundamental building blocks.
The difficulty with vortices is the Math, and the fluid dynamic equations. However today we have powerful computational machines , techniques and methodology that can do that which Newton and other computation al prodigies could not do to the required proficiency and accuracy.
Why bother? We have found methods and depictions, chiefly particulate that are just good enough and have guided technological advance have we not?
What many now realise is that very facility has locked our minds into power games that attempt to assert something I can never know: ultimate reality.
Well those games are falling to pieces through assertions of dark matter, dark energy and dark holes!! . The simplicity once promised has now become mindbogglingly complex. If it is in fact complex, let us start with a complexity we can observe , and that is rotational fluid motion.
The theory of charge( electric) in a magnet charge or field is not intuitively helpful, so electric theorists have replaced magnetic charge by Faraday Tubes of magnetic for d, pressure and induction, acti g on charged particles. However in wave mechanics we can model the interactions by rotational dynamics USO g propagation by variation of tensile( intensive) forces in a medium, and explain reflection , refraction, dispersion / diffraction by these means giving simple whole number relationships or quantised relationships. We can also model probability b rotational formulae. .
I have attempted to draw attention to Aragos disc discoveries relating to diamagnetic materials and the noticed charge differential, famously used in homopolar motors, and the work done to develop the hall effect sensor and the Langmuir probes. . In this regard the methodology of 3 mutually orthogonal Hall effect sensors is crucial to appreciating what Johnson et al have done. . The careful interpretation of what they have measured can support both the wave and the particle interpretation , but ultimately the wave interpretation, though more complex is more fundamental.
The wonderful contour and surface maps of the data are only part of the information encoded! . Careful interpretation is needed because many and I include myself, want to simply rotate the contour maps to form a doouble torus at each. So called pole. David LaPoint is one of these in his primer series. . However his bowl shaped magnets can be analysed by The Joh son et al method which will reveal something different is in fact going on!
The discovery of the spin vortex is a complex analysis. Ferro fluids support the spin conception easily nowadays, but the work done by Johnson intimates much more! . Any simple spin vortex description is likely to mislead, and this is why their description of spin, bases on as symmetric time motions or as Leonard Suskind put it: fractal motions that devolve into the arrow of time is so important.
I have a lot more research to do in modern spintronics but particle descriptors aside, the rotational dynamic is clear and indisputable, despite what quantum theorist might say!
