#Cow magnet how to
Consult veterinarian on how to administer the magnet. Cow magnet, also known as the rumen magnet, cow stomach magnet, or cattle magnet, is a veterinary medical device for the prevention of hardware disease. When properly administered, one cow magnet will last the life of the cow. Cow magnets help prevent this disease by attracting stray metal from the folds and crevices of the rumen and reticulum. The cow loses her appetite and decreases milk output (dairy cows), or her ability to gain weight (feeder stock). Tramp iron tends to lodge in the honeycombed walls of the reticulum, threatening the surrounding vital organs and causing irritation and inflammation. This heavy-duty magnet collects nails, staples, and baling wire (also called tramp iron) that cows swallow while grazing. Can also be used for classroom experiments including demonstration of magnetic fields. Ru-Master 5™ cow magnet is our patented design, used to prevent hardware disease in cows. It looks the same as my older cow magnets but they do not have a magnetic field similar to a bar magnet.0.750'' Dia. I have some newer cow magnets that have several small magnets inside an aluminum case. If you order cow magnets, you might get something that is useful for cows but not physics. I tell students that I got these magnets on the cheap end because they were already used. Magnets play two roles in preventing hardware disease. The cow magnet is then placed in the cow to attract these iron objects and prevent them from getting into the small stomach parts.

Simple Attraction: Cow magnets do their job by catching metal items and preventing them from doing damage. If these staples and nails get into the smaller parts of a cow's stomach, it can cause damage. However, sometimes this "stuff" that goes into the cow is non-grass objects like old staples and nails. What is a cow magnet? Apparently cows eat stuff on the ground. They happen to work fairly well for experiments that require a bar magnet. I like this magnet because of the box that it came in. There is another magnet I was going to look at, but perhaps you can determine it's dipole moment as a take home lab assignment. Here is this plot using the compass with a small red bar magnet (shown above). Record both the field strength and the distance. Use the different methods of measuring the magnetic fields and find this field at different positions from the bar magnet. Determining the Magnetic Dipole MomentĬould you just measure the magnetic field at a certain location from a bar magnet and call it a day? Sure, but that wouldn't be much fun - would it? How do you measure the magnetic field anyway? Didn't I just go over that? Yes, I did but you weren't paying attention. A bar magnet with a greater dipole moment will create greater magnetic fields. Using the same idea for a bar magnet, we can say that it has a magnetic dipole moment - μ. This weekend I went with my family to a Robotic Dairy Farm. It would actually be a vector, but just don't worry about that for now. Cow Magnets Customer Contribution: Our customer Joel Montvelisky send us these photos and write the cow magnet’s archive. We can call the product of q and s the electric dipole moment. I hope it's clear that q is the magnitude of one of the charges (the net charge of a dipole is zero).īut wait! How can we use and expression like this for a bar magnet? Magnets don't have two "magnetic charges" in them, do they? No, they don't. This result is only an approximation for the case that r (the distance from the center of the dipole to the location of the field) is much greater than s (the distance between the two charges in the dipole).
