Appendix: The Beginner’s Guide to


Magnetic Field Shielding For Overhead & Buried Powerlines

In this appendix section, you’re going to learn about the active field cancellation of magnetic fields.

This is one of the truly effective ways to lower magnetic field levels originating from external sources like overhead powerlines.

It may not be in everyone’s budget, but, depending on your circumstances, it may be worth checking out.

Active Field Cancellation of External
Magnetic Field Sources

Charles Keen at EMF Services, LLC provides active field cancellation systems for residential and commercial sites.  These individualized solutions are one of the only effective means of shielding against external magnetic field sources, such as overhead or buried powerlines.

About his systems, Charles writes:

Active shielding systems are used primarily for reducing powerline magnetic fields. They are effective for both transmission and distribution lines, overhead or underground. Within a defined area, the magnetic field can often be reduced to a very low level.

A preliminary determination of the applicability of active shielding for a specific location can often be made from a quick look at the property address in Google Maps.

Unfortunately, about 50% of residential cases that initially present can be ruled out in the course of a quick phone call, usually due to inadequate space on the property. But under the right circumstances, this technology can represent an effective solution to the problem.”
