## Abstract

A method for providing magnetic fluid treatment in which at least one electrical conductor comprising at least one length of an electrical conducting material having a first conductor lead and a second conductor lead is energized. The electrical conductor is coiled with at least one turn to form at least one uninterrupted coil of electrical conductor encircling at least a section of an outer surface of a conduit. Energizing the at least one electrical conductor establishes a magnetic field having lines of flux directed along a flow path formed by the conduit and concentrated in a non-magnetically conductive region located between two magnetically conductive regions. A fluid is directed through the conduit past the non-magnetically conductive region to provide magnetic fluid treatment to the fluid.
