<p>A magnetic source and condenser for creating magnetic flux within a ferrous pipe (P) comprises a rectangular magnet (M) having a pair of opposing major faces and a pair of pole pieces (N and S) sandwiching the magnet. The pole pieces each have a foot (Nf and Sf) extending under the magnet and adjacent the pipe. By virtue of the pole pieces and feet, the magnetic flux from the magnet is condensed before it is applied to the pipe. Thus the condensed flux is strong enough to exceed the flux carrying capacity of the pipe so that it travels away from the pipe in an arc (G) where it cuts perpendicularly the fluid flow (F) within the pipe. The magnetic flux ionizes the fluid and charges the pipe negatively to protect the pipe from scale, corrosion, algae, and parafinning.</p> |
