Hi LGL,
The experimental physicist's traditional way of handling this is by using
'Mu Metal' a very very soft iron alloy that 'traps' the magnetic flux;
quite effective and quite expensive: ~$800 to cover a 15" monitor.
Fortunately, mild steel is quite 'soft' magneticly. I've used !/4" thick
X4"wide by about 16" long to shield between a monitor
