Roy and Clas,
	I welcome your carefully reasoned comments.  I too am concerned about
deliberately subjecting yourself to fluctuating magnetic fields, without some
kind of risk/benefit analysis.  We know, that some values of fluctuating
magnetic field intensity (at specific frequencies), coupled with a fixed
magnetic field component (the earth's field) can significantly affect the rate
of ion flow across cell membranes - hence the ability of cells to communicate
with each other.  Dr. Carl Blackman has studied these effects for 10 years.  
	I urge your readers to consult the web site http://www.eecs.uic.edu/~emmed/
to see the program of a conference on Electromagnetics in Medicine that was
held in Chicago in 1997.  A similar conference was scheduled to be held in
Toronto about two years later, but I don't know anything about that meeting. 
In the Chicago meeting, which was chaired and organized by Dr. James Lin, a
noted bioelectroimagnetics researcher at the University of Illinois, there
were papers about both the detrimental and the therapeutic aspects of
electromagnetic fields from researchers from institutions (mostly
universities) all over the world.  At least looking at the titles of the
papers might give readers some indication of who is doing what, if they wish
to contact experts in this area.  I don't think these experiments should be
done without some understanding of the potential consequences in terms of long
range effects.
