Lynn,
Mag-lights make good flashlights (aluminum so non magnetic), but the real
problem is the batteries which tend to be very magnetic. I have also
succesfully used some fluoresent type lights from sears (Craftsman brand)
that were mostly non-magnetic (plastic) which plug into the wall, so no
bateries, however they have a tendency to turn themselves off if brought to
close to the magnet. (The bassalt is also magnetic).
I have not used hair dryers, but I have used heat guns in the past that are
mostly plastic (bought at wal-mart, sears or home depot) but again as with
the flashlight it is often the inner workings that are magnetic. They can
be used with care around magnets (I have worked from 1.5T to 7T with these
instruments and currently I work with a 4T human system where we have used
both heatguns and Mag-lights (the MINI's).) We have also broken a few of
the heat guns (burnt out the motor or element I presume) from using them to
close to the magnet (to far inside the field). If you hear of any other
suggestions I would also like to know.
With both of these types of equipment it is important to keep a good hold on
them, as even though there are mostly non-magnetic, that also means they are
some what magnetic, and so can be dangerous if you are not being careful.
I hope this has been helpful.
