The Maxi Mag magnet is a powerful, high density, high-energy poly-coated ceramic cattle magnet with superior pulling power. When in the cow's stomach, metals on the magnet can be repositioned with minimum pressure on the reticular wall, reducing punctures. The magnet remains inside the cow for the life of the animal (and apparently can be reused afterward), and the presence of the magnet and the attracted metal in the rumen apparently has no effect on the cow’s health or lifespan.
