Description
These Cast Alnico 5 "Cow" Magnets were the original magnets developed to be inserted in a cow's stomach to collect any ferrous metals that a cow may unknowingly ingest while grazing. This prevents what is called Hardware Disease in cattle. They are great for a multitude of projects all limited by your imagination. AZ Industries, Inc. has been in business for over 50 years.
