  • Patent number: 4390423
    Abstract: An apparatus for the magnetic treatment of a flowing liquid includes an elongated housing, which is made at least in part of a ferromagnetic material and which defines a liquid flow channel therethrough, and at least one elongated permanent magnet positioned in the flow channel. Each elongated permanent magnet has at least one elongated pole shoe associated therewith which includes a projection portion which extends into the flow channel so as to form a narrow gap between its top and either the inside wall of the elongated housing or the top of the projection portion of another pole shoe. Each projection portion is elongated in the direction of the flow channel and is angled such that the gap formed thereby is elongated and is oriented at an acute angle to the flow direction of the liquid passing through the elongated housing. The flowing liquid must pass through a formed gap and thereby be subjected to the influence of a magnetic field.
