Abstract: A cow magnet is provided having minerals that have been found useful for good health. A cow magnet of Ferrous Oxide (FeO) and stable Strontium (Sr) is discovered to be healthy. Stable Strontium (Sr) is discovered to be used by the bovine body to increase bone growth and strength. Iron (Fe) is known to be used by the bovine body for healthy red blood cells.
