I've got some direct experience testing computers and set-top boxes to see
if they meet emissions standards or are susceptible to interference from
outside energy sources (but not specifically induction loop powered
devices). The tests we did were carried out hundreds of feet down an
underground salt mine to screen the equipment under test from other sources
that were outside our control (like local radio stations and taxi
companies). The test equipment we used had a total value or around $250,000
although we usually hired it along with time down the mine. Even with all
this equipment and expertise it was always a nightmare trying to ensure
equipment under test met the required standards.
If you submit ANY electronic device to sufficient interference it will
malfunction - the problem is knowing if the level that it tollerates is
acceptable in the real world. That takes an expert with experience. If you
are thinking of making a significant investment in a company that's making
induction loop devices you should probably ask to see their product test
reports and have a professional engineer look at them. I wouldn't consider
myself qualified despite the experience I've had.
Oh and you could use 9V. It's quite possible for a low voltage source to
produce high currents (even 100's of Amps). The 12 V battery in your car
does it every time you start up.
