About this item

  • PROTECTS COWS FROM HARMFUL EFFECTS OF INGESTING METAL OBJECTS: The original Ultimate Heavy-Duty Ru-Master 5 cow magnet, Master Magnetics' patent #5128644. For more than 50 years it has been the favorite of dairymen and veterinarians to protect livestock from damage associated with ingesting metal objects.
  • SMOOTH CYLINDER SHAPE: 0.75" diameter, 3.375" length (19.05 mm diameter, 85.725 mm length) with stainless steel connector rod through the core and rounded steel end caps. Rounded ends and slightly heavier than other cow magnets. These qualities make it easier for the magnet to travel to the stomach.
  • POWERFUL: Ceramic (Ferrite) magnets and steel rings are divided into segments to create superior strength. Consistent pulling force along the length aligns tramp iron parallel to the magnet.
  • ONE MAGNET WORKS FOR THE LIFE OF THE COW: Administer with ordinary balling gun. Magnet does not lose power.
  • MASTER MAGNETICS: We manufacture magnetic products for commercial, industrial, and consumer use. Our goal is to create reasonably priced products that make your life easier. Our products will help you realize the value of magnets and their many uses!


What are Cow Magnets? Cow magnets are popular with dairy farmers and veterinarians to help prevent the harmful effects of cattle ingesting metal objects. 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 reticulum, threatening the surrounding vital organs and causing irritation and inflammation. The cow loses her appetite and decreases milk output (dairy cows), or her ability to gain weight (feeder stock). Cow magnets help prevent this by attracting and holding stray metal from the folds and crevices of the rumen and reticulum.

What is there to dislike they do the job. Better quality than what I can get from the vet for more money.
