Sintered ferrite magnets are available in isotropic magnets and anisotropic magnets.The magnetic properties of isotropic ferrite are low. Since they have nearlythe same magnetic properties in all directions, so isotropic ferrite magnets can be magnetized in many different directions or in multi-poles and especially in magnetic field where anisotropic ferrite magnet reaches 1,600Gs to 1,700Gs,Producing this type magnet with grade N30 to N45 or with patent high temperature of M, H, SH, UH, EH seriesThe sintered NdFeB magnet has the high remanence,high coercive force,high energy product and high ratio between performance value and productcost.Especially suitable for used in Micro products of Auto,Motor,National defence,Speaker,Computer,Biology project,Medical treatment machine,Instrument and Meter etc.Any special specification can be produced.

Cow magnets are popular with dairy farmers and veterinarians to help preventhardware disease in their cattle. 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, known ashardware disease. The cow loses her appetite and decreases her milk output (dairy cows), or her ability to gain weight (feeder stock). Cow magnets help prevent this disease by attracting stray metal from the folds and crevices of the rumen andreticulum. One magnet works for the life of the cow. These cow magnets also make a great addition to your science project. They are very powerful and are great for general experimentation with magnets.
