Certificated Rare Earth Permanent Neodymium/AlNiCo/Ferrite Cow Magnet
Cow do not use lip to discriminate between materials and also do not completely chaw feed before swallowing. They eat everything from regular grass and dirt to nails and wires. These objects tend to lodge in the honeycombed walls of the reticulum, hence threatening the surrounding vital organs and causing irritation, inflammation and worse, known as hardware disease. Hardware disease will lead to cows loses appetite and decreases milk output, or her ability to gain weight.
What is Cow Magnet
Cow magnet is a kind of veterinary medical device for treatment and prevention of hardware disease. Farmers and veterinarians apply cow magnet to fight hardware disease by attracting metal from rumen and reticulum.
Cow magnets are inserted in to the cow's mouth by farmers or veterinarians, then lodge in cow's second stomach and attract stray metal on its way by. Finally holding it in a safe place.
Product A:
Dimension: D12.7 x 76.2mm.
Magnet type: Alnico casting magnet.
Most traditional rod-shaped Alnico magnet, and this kind of magnet has been already used for over 30 years. Actually, the attractive force cannot fully be utilized during use.
Product B:
Dimension: 65 x 16 x 13mm.
Magnet type: Sintered ferrite magnet.
The magnetization pattern is different from simple block magnet. Black epoxy resin coating will help magnet to avoid chipping.
Product C:
Dimension: D18.5 x 79mm.
Magnet type: Sintered ferrite magnet.
Special magnetic circuit design generates more working areas and higher attractive force. Dominant one in market nowadays.
Product D:
Magnet type: Sintered ferrite magnet.
Magnets and protective plastic framework form a cage design to increase effectiveness of cow magnet.
Product E:
Dimension: D12.7 x 76.2mm.
Magnet type: Sintered neodymium magnet
The dimension of this cow magnet is same as Alnico one. NdFeB magnets and special magnetic circuit provide excellent performance, and its attractive force much higher than Alnico's.
