3rd Revised Edition by Karl Riley, © 2007 A trouble-shooting guide for electricians who are asked to find the sources of unusual AC magnetic fields in buildings. Since most of the sources are due to mis-connections which violate NEC, the steps for measuring, tracing and correcting the faults are spelled out in detail with many illustrations. Grounding to water pipes is another source which can be modified; the book goes into grounding and its myths in depth. An electrician who absorbs the material in this book will feel comfortable dealing with customer concerns about magnetic fields in their buildings, and will know how to proceed to reduce or eliminate those fields.
