The instant invention prevents the formation and accumulation of contaminants within conduits and on equipment utilized in the transportation, delivery and processing of fluid columns. It may also be utilized to accelerate the separation of oil and water and increase the efficiency of oil/water separation equipment. ## Claims ### Claim 1 A method of fluid treatment, comprising: (a) establishing a flow of a fluid to be treated along a flow path extending through a fluid entry port of a magnetically conductive conduit, wherein at least a section of an outer surface of the magnetically conductive conduit is sleeved with at least one coil core; and (b) establishing a magnetic field having lines of flux directed along the flow path of the fluid and concentrated in a plurality of distinct areas along a longitudinal axis of the magnetically conductive conduit. ### Claim 2 (depends on 1) The method of claim 1 further comprising directing the fluid to pass through at least one non-magnetically conductive fluid flow conduit to promote the flow of the fluid through the magnetically conductive conduit. ### Claim 3 (depends on 1) The method of claim 1 further comprising dispersing at least one fluid treatment chemical into the fluid after establishing the flow of the fluid to be treated along the flow path extending through the fluid entry port of the magnetically conductive conduit. ### Claim 4 (depends on 1) The method of claim 1 further comprising the step of directing the fluid through at least one contaminant separation process after establishing the flow of the fluid to be treated along the flow path extending through the fluid entry port of the magnetically conductive conduit. ### Claim 5 (depends on 1) The method of claim 1 further comprising the step of directing the fluid through at least one fluid flow conditioning process. ### Claim 6 (depends on 1) The method of claim 1 further comprising dispersing at least one fluid treatment chemical into the fluid before establishing the flow of the fluid to be treated along the flow path extending through the fluid entry port of the magnetically conductive conduit. ### Claim 7 (depends on 1) The method of claim 1 further comprising the step of directing the fluid through at least one contaminant separation process before establishing the flow of the fluid to be treated along the flow path extending through the fluid entry port of the magnetically conductive conduit. ### Claim 8 A method of fluid treatment, comprising: (a) establishing a flow of a fluid to be treated along a flow path extending through a magnetically conductive conduit, wherein at least a section of an outer surface of the magnetically conductive conduit is sleeved with at least one coil core; and (b) establishing a magnetic field having lines of flux directed along the flow path of the fluid and concentrated in a plurality of distinct areas along a longitudinal axis of the magnetically conductive conduit. ### Claim 9 (depends on 8) The method of claim 8 further comprising directing the fluid to pass through at least one non-magnetically conductive fluid flow conduit to promote the flow of the fluid through the magnetically conductive conduit.
