Hi, I have a rather general question (or maybe its rather silly question to
ask). I would like to get some input and suggestions (hopefully you will
have some technical references to support your ideas). I am interested
knowing off-hand what specific types of geometrical formations and
orientations of a magnetic particle (say magnetite or some other
paramagnetic derivative) would be required in order to maximize the local
field effects of an electromagnetic field and/or elicit the greatest current
induction within some unit of space.

I'm working under the hypothesis that the geometrical organization as well
orientation within three dimensional space will be a benefical factor in
order to maximize the effects that i mentioned above. I am just interested
in knowing off hand of some configural spatial organizations (that occur in
nature) that might be capable of enhancing the responsiveness within
piezoelectrical materials (or just magnetic crystals). So any suggestions
will be great. Thanks.

For the sake of efficiency, I suggest not to mix natural magnetism AND
natural piezoelectricity. IMHO, mineralogy, crystallography and chemistry
of natural ferromagnetic and paramagnetic species do not seem to follow
common simple principles in the details (mainly in the minor element
contents). Much work has been done on factors affecting whole rock
magnetism, but as for the crystalline deep-seated details, definitive
advances have been achieved when working on synthetic spinels. I guess
that if you look after "rock magnetism and particle orientation",
"magnetism and crystal structure", etc., you will sort out the good
references. There are also several geophysical prospecting and mapping
methods more directly relevant to your electromagnetic field/current
induction querry. J.J.

Do you have any suggestions of texts or papers that I should evaluate which
talk about crucial geometrical and spatial orientation characteristics for
optimizing electric and magnetic fields?
