Do you know why are these magnets called cow magnets? Cow magnets are popular with dairy farmers and veterinarians to help prevent Hardware Disease in their cattle. While grazing, cows eat everything from grass and dirt to nails, staples and bits of bailing wire (referred to as tramp iron). Tramp iron tends to lodge in the honeycombed walls of the recticulum, threatening the surrounding vital organs and causing irritation and inflammation, known as Hardware Disease. The cow loses her appetite and decreases her milk output (dairy cows), or her ability to gain weight (feeder stock). Cow magnets help prevent this disease by attracting stray metal from the folds and crevices of the rumen and recticulum. One magnet works for the life of the cow! These cow magnets also make a great addition to your science project. They are very powerful and are great for general experimentation with magnets. Size: 3in (75mm) long, 0.5in (12mm) in diameter Color: Shiny silver.
