What is cow magnet

Cow magnets are primarily used to prevent hardware disease in cows. Hardware disease is caused by cows inadvertently eating metal like nails, staples and baling wire, and then the metal settles in the reticulum. The metal  can threaten the cow’s surrounding vital organs and cause irritation and inflammation in the stomach. The cow loses her appetite and decreases milk output (dairy cows) or her ability to gain weight (feeder stock). Cow magnets help prevent hardware disease by attracting stray metal from the folds and crevices of the rumen and reticulum. When properly administered, one cow magnet will last the cow’s lifetime.

Alnico cow magnets are composed of aluminum, nickel and cobalt, and they sometimes contain copper and/or titanium.

Ceramic cow magnets are composed of iron oxide and barium or strontium carbonate.

5 ferrite cow magnets are composed of our patented design which features five powerful ceramic magnets strategically assembled with power-enhancing pole pieces for superior magnetic strength.

However, some customers choose NdFeB cattle magnets because of the insufficient magnetic properties of AlNiCo and ferrite cattle magnets. Because NdFeB cattle magnets have the strongest magnetic properties, and it cover with the iron part  , And the working temperature can only be below 80 degrees Celsius.

From an economic point of view, ferrite bull magnets are the best choice. The price of 5-ring ferrite bull magnets is about 0.5 to 0.6 US dollars, the price of green plastic bull magnets is about 0.4 US dollars, and the prices of other products are above 1.5 US dollars. . And our company specializes in serving the Japanese Kobe beef supplier. The aluminum nickel cobalt cattle magnet is selected, which has the advantages of strong corrosion resistance and stable performance.

Cow magnets can also be used for 3D classroom experiments to demonstrate magnetic fields and a variety of investigations.
