Abstract
A method and apparatus for conditioning fluid flowing through a conduit in which two coils (50,60) are coiled around the conduit at different locations and connected to a circuit (40) which generates square wave signals which are alternately fed to the two coils (50, 60). The frequency of the square wave is ramped repeatedly from 1.5 Khz to 60 Khz.
