• ALNICO MATERIAL - Made of durable alnico (stronger and more durable than ceramic magnets, yet more economical and safer than rare-earth neodymium magnets)
• SIZE - Measures 3 inches long x .50 inch in diameter
• SCIENCE LEARNING TOOL - Great for hands-on science experiments for school, home, science fair projects, STEM clubs, and more!
• COOL CONVERSATION PIECE - Show your friends--hand your magnet to them, explain how it helps cows, and see how your friends react! (Don't worry, OUR cow magnets sold here have never been inside cows!)
• CARE - Be careful not to drop magnets or bang anything against them. (When a magnet is subjected to an outside force, its magnetic domains can be jumbled, causing it to lose its magnetism.)
• STORAGE - Keep alnico magnets away from very strong magnets such as rare-earth

This 3" long cylindrical magnet is world famous! There's one inside every cow! You can do all kinds of cool things with a cow magnet, but cow magnets were originally used as a tool to save the lives of cows, which eat everything from grass and dirt to nails, staples and bits of bailing wire (referred to as tramp iron). A cow has 4 compartments in its stomach, and when these tramp iron items work their way through, they cause all kinds of problems, threatening the surrounding vital organs and causing irritation and inflammation, and worse. When a cow swallows a cow magnet, it lands in the first compartment of the stomach, and attracts the stray metal on its way by, holding it in a safe place. Sold as a pack of 2 cow magnets.
