Abstract: An apparatus and method for preventing and minimizing the formation of deposits of parrafin, asphaltene and scale on the inside of downhole oil string line and on the surface of flow transmission lines, by increasing the turbulence of various electrically-charged microscopic particles populating crude oil colloidal suspension, using effects of the Lorentz force acting upon such flowing fluid. A plurality of spaced-apart permanent magnet disc assemblies is disposed perpendicularly of a fluid flowing through conduits and the like, and is specially configured to provide a unique helicoidal trajectory of the various electrically-charged microscopic particles, subjecting these particles to a prolonged exposure to an intense magnetic flux. As the fluid experiences lamellar flow through the centrally located passageway, the charged particles exhibit turbulent, helicoidal flow through concentrated magnetic lines of force.
