Increasing the Distance from the Source

Frequently, the most cost effective means to reduce AC magnetic field strength in an area is to simply increase the distance between the affected device and the source of the interfering AC magnetic fields (electrical panels, circuits, etc). AC magnetic fields fall off quickly with distance; moving a jittering monitor further away from a circuit breaker in the wall may be the best solution. Often, a relatively small change in location or orientation of the monitor is sufficient to reduce or eliminate the image jitter.

Other situations may require relocating the electrical equipment (the source of the fields) to another area. Though effective, moving conduit, electric service panels or transformers can be expensive and disruptive. In many cases too, it may "cure" one area, while creating a new problem elsewhere.

If the source of the magnetic fields cannot be moved, then possibly the affected equipment or area can. An option is to redesignate the use of the area affected by elevated magnetic fields. In buildings where space is not an issue, an affected office area can be converted into storage or a meeting room, because it cannot support computer use. When space is more of a commodity however, downgrading prime office space is undesirable and ultimately expensive in lost utility and possibly lost revenue.
