most coils operate at LF which means that the operating wavelengths are
very long ( 100kHz having a wavelength of 3000m). The near field of an
antenna at this frequency, given by lambda/2*pi is approx 500m so the
fields that someone experiences are high electric fields.
There is little or no information available re the effects of these so
called induction fields on the human body. Most studies are for higher
frequencies whereby the structure of the human body is such that its
dimensions approach a wavelength (e.g. the human eye). There is a lot
of concern regarding PCN devices such as cellphones and there are no
Electronics and Wireless World has run a series of articles on power
line frequency effects; the conclusion is inconclusive. The Swedes are
doing a lot of studies; it is known that high E field gradients can
cause migration of chemicals within cells but the effect has been seen
in Petri dishes, not people.
We don't want to confuse the effects of sticking your head inside a
microwave oven with the possible effects due to LF fields and I say that
the mechanisms of damage will be different if they exist, but no one has
much of an idea really.
