I used to have a problem with PC monitors 10 years ago, but not with modern
ones (I just checked and needed to be within 6 inches from my monitor before
I could hear interference on "T"). I have never noticed any problem with
magnetic secrity tags or other security systems used in libraries, either -
or fluorescent lights.
The only situation where I have experienced interference is certain mains
electrical installations, as recently mentioned by Chris. I hasve been
informed that this arises when the electrical cables circle the room, thus
creating an electrical field in a similar way to a loop system. The only
remedy suggested was to re-wire the room.

The interference noise that induction loops pick up is usually
caused by the magnetic fields produced by other electonic
equipment. Computer monitors produce a strong madnetic field,
which is why loops in close proximity to computers have problems.
TFT flat screen monitors do not have magnetic fields and are
therefore best on reception desks etc where loops may be used.
In libraries one has the problem of the magnetic security tag
machine scanner thing at the issue desk, causes interference, 'cos
its a magnet.
But I'm sure the blessed Gordon can advise.
