Abstract: A magnetic force field generator is provided which is adapted to be mounted onto a conduit for treating fluid flowing through the conduit with a magnetic force field of alternating polarity. The generator includes a non-magnetic housing having a longitudinally extending passage for receiving the conduit and a strap device for securing the housing to the conduit. A unitary magnet is provided which is embedded in the housing and is positioned in the same longitudinal plane as the conduit. The magnet has an odd number of sections of alternating polarity, each adapted to generate a discrete magnetic force field in the conduit as the fluid flows therethrough. When the fluid is a fuel, it is preferred that the most upstream section and the most downstream section of the magnet be each adapted to introduce a south polar magnetic field in the inner area of said conduit.

Abstract: A system for monitoring one or more factors relating to the strength of a magnetic field generated by a magnetic force field generator adapted to treat fluid flowing through a conduit. Sensors detect and respond to any change in the factor monitored and actuate means to effect a reversal of such change for maintaining the strength of the magnetic force field to within allowable limits. The system includes a multi-magnet magnetic field generator which generates a plurality of discrete magnet fields of reverse polarity positioned externally of the conduit for saturating the inner area of the conduit for treating fluid flowing through the conduit.
