Anyone have a source of information about the effective range of a magnetic field that would cause damage to computerized or other electronic equipment? I'm researching an option to use rare earth magnets to assemble something, but I want to make sure that it won't screw up the electronic equipment that will be close to the magnets (but not in direct contact).

If magnets and electromagnets were never invented, it is likely computers would not exist. The first computers required the magnetic properties of relays and/or vacuum tubes to function. Even modern computers rely on magnetics to spin fans, spin hard drives, CD/DVD drives, produce sound, provide power through the power supply, increase voltage through induction, rectify power flow, and read/write data to hard drives, floppy drives, and other magnetic media.
They already have ! We used to write ideas on pieces of stone, then we discovered how to make paper. After that, we started recording ideas on magnetic tape, and now through technological advances, we use digital dictation devices and computers !

This coloured effect is caused by residual magnetic fields on the shadowmask of a cathode ray tube tv. When a tv is switched on an alternating electrical current is passed through a coil looped around the crt face, this eliminates these stray magnetic fluxes. There may be a fault with this circuit. A magnet brought into proximity with the tv screen can permanantly magnetise the shadowmask or flex it out of position.

FRINGING EFFECT:Fringing effect is the magnetic characteristic caused by the shape around directly opposing the magnetic surfaces.
The use of magnetic tape improved the performance of computers by giving them the ability to read and write data quickly and reliably.

Yes, it is commonly known as magnetic deviation
Magnetic bracelets work according to the placebo effect. I f you think they work then they do. Magnetic bracelets are harmless but no serious scientific study has revealed any effect other than the (important) placebo effect.
