A cow magnet is a large magnetic pill (2 1/2" long x 1" thick) that is put into a cow's stomach (specifically the reticulum). It collects any screws, bolts, nails or wire or anything else the cow may pick up along with the feed she eats. Magnets prevent what is called "hardwire disease," which is a malady that occurs when a foreign object punctures the stomach wall (primarily the reticulum), and bacteria enter from either outside or inside the cow's stomach causing infection, weight loss, and loss of appetite. The magnet keeps all of the hardware together in one spot when the reticulum contracts as the animal eats.

The exact same way that a normal magnet attracts metal.


How does the built in magnet of a cow work?

Cows don't have "built in magnets." Magnets are inserted down the throat of a cow as a way to prevent her from getting hardware disease from eating too much scrap metal like nails and wire. The magnet in a cow works exactly the same as any "normal" magnet does.

You can't. It doesn't matter which end of a cow magnet is North or South. As long as it can pick up metal and the metal sticks to it, then it works just fine.

Just get a fairly strong magnet, I used a cow magnet. Wrap the magnet in a cloth so as not to scratch the face of the panel. Place the magnet over the needle and rotate it counter clockwise. If the magnet is strong enough the needle will return to its proper position.

What do you do if a cow eats a nail?

Go to your vet, buy a bolus-pill plunger and a pack of bolus magnets (some call them cow magnets). Restrain the cow, put the magnet pill in the plunger, open the cows' mouth, put the plunger at the back of the cows' throat, and pop the pill in. The magnet will stay in the cow's reticulum (the "hardware" stomach where bits of metal and string accumulate), picking up the nail she just ate as well as other things she ate by accident. The magnet will help keep the hardware from puncturing her stomach, causing infection and a malady known as "Hardware Disease."


How are magnets used with cows?

Some cows have magnets inside their stomachs! The magnets attract any metal that the cow might accidently eat, which would harm or kill the cow if it passed through the digestive system. A cow can keep a magnet inside the stomach for it's entire life without harm.
