Hello,

I've a very sensitive experiment in which an air coil is the pickup sensor.
We have an unexplained residual error and after carefully eliminating all
the possible causes, the obvious and less obvious ones, we finally found the
cause was "in" the pickup coil itself. There's no doubt about this now.

Some more experiments led us to one hypothesis where the air oxygen which,
is paramagnetic, interacts with the system and I'm now trying to put some
figures on this hypothesis.

My pb is that I don't know how to work out magnetic problems with gases and
I don't find much information on web.

I can't say much on the system but our hypothesis has to do with linearity
of the medium (air) and saturation.

Any hint on how to tackle this is welcomed.

Thanks,

Helmut has the right idea. Exclude the O2 by enveloping your P/U with
a benign gas such as N2 or argon, if your experimental design
permits. If not, get back to us with a little more detail on what you
are trying to accomplish and we will try to advise you further.
