[ausev] Trike conversion: Remedial EM Sheilding question.

[Clendon Gibson]

It's interesting that you ask about magnetism, as opposed to electric flux. 

I am guessing that part of the reason this has not been studied more is that magnetic fields, even from very powerful sources, tend to be quite weak. An exception are the magnetic fields generated by a Magnetic Resonance Imager (MRI). These are strong enough that as precautions people should not wear jewelry when being examined by them.  Because the jewelry might be forcibly removed from their person if it happens to have ferrous metals.

As a point. A copper mesh will do nothing for a magnetic field. Electric fields, yes, Magnetic ones, nada.

Erik,
Thank you for your response.
I have read about gaussmeters and others in scholars'
papers for "physics non-majors", wherein the proximity to the feild source
is the highest covariable as to interference.
But electronic interference isn't the concern.
 It seems that there are not published studies of any kind,
or maybe no-one can even imply any kind of advice with this, but maybe if I
frame the questions differently from a humorous perspective, then maybe that
might work to get some direction to some website that isn't for physics
majors or non-majors.

  It is simply the proximity of my butt to the electric motors' flux feild,
not even getting to interference yet,
(which, if my butt is not getting slowly fried with colon and prostate
cancers, for example, then the rest is elementary as far as I am concerned.)
(My attempt at humor is next;)
  I seem to have a problem communicating that it is my very butt getting
slowly fried that must get through all of the technothought/levels of
priorites other than getting my butt slowly fried.
 Let us have some fun with this line of thought so that I am clear.
  If the flux density of 15.000 watts for only 30 minutes a day will only
fry my butt slowly from a perspective of a month or so, then we may not
wisely proceed with this project quite yet as to planning a design.
  If the flux density of 15,000 watts is somehow marginally sheilded,  for
only 15 minutes a day, and will only fry my butt slowly from a perspective
of a year or so, then we may be getting closer to something that works, such
as a copper mesh net as suggested previously to me.
  If the flux density of 15,000 watts for 1 hour a day for 20 years will fry
my butt slowly from a that perspective, then we certainly are getting
somewhere toward how to design this remedial sheilding if there is something
possible to that end (ahem), or mine.
