Title: Magnetic seed treating device

Abstract: A device for magnetically treating seeds prior to planting so as to increase the yield of plants grown from the seeds. The device includes a tubular member provided with an internal support for securing a permanent magnet therein so that as seeds are poured through the tubular member, they are magnetically treated. The magnet, which has opposite poles disposed at opposite ends thereof, is oriented with its longitudinal axis extending in the direction of the passage, the passage adjacent the magnet being of substantially annular shape in cross-section whereby a uniform cylindrical shaped magnetic field occupies the annular passage through which the grain must pass. The tubular member has a converging portion in the direction of seed travel so as to provide an area of maximum constriction adjacent the magnet which results in the seeds being funnelled radially inward towards the more concentrated magnetic field closest to the magnet. The converging or constricted portion may be shaped to provide the flow of seeds along streamlines so that the rate of flow is enhanced.
