Product Description

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. Warning: Choking hazard.Small part. Not for children under 3 years of age

I use these magnets during contruction to find nails or screws in the wall while doing "surgical demolition". I place a piece of surgical tubing to 1 end and holding the tubing end, run the magnet along the wall. When it finds a fastener, the end holds to that position. Note that only the ends attract anything. Great little tool.

These magnets have many uses other than cattle. I use mine to locate studs in finished walls (via the sheet rock screws or nails), to retrieve items dropped in hard to reach places, heck, I even used it to remove a small chunk of ferrous metal that became lodged between my eyelid and eyeball! They also can be held up next to most commercial fire alarm systems' smoke detectors to trigger them (for testing purposes only!!! :P ) I wish I had several more of them cause magnets are fun!!!!
