★ coercive force: the coercive force means that the material properties of the material to resist demagnetization of a measure (H), the coercive force greater ability to resist demagnetization effect means that the greater the material, its symbol Hcj, Rally magnet specifications, unit: Koe or KA / m, Rally magnets, 1Koe = 79.6KA / m ★ BH: At any point on the permanent magnet flux density and magnetic field strength of the product any demagnetization curve is called energy product, Rally magnets classification, it is One measure of the total energy of the generated magnetic field of the permanent magnet unit volume storage genre external magnetic field center, the unit represented by MGoe, original Rally magnets, commonly referred to as N35 grade 35 refers to the greater of the maximum value of its product (BH magnetically stored per unit volume of greater means, that is, the better the performance of the material. ferrofluid (ferrofluid, ferrum Latin "iron" and fluid "fluid" portmanteau of two words) is a strong presence in the magnetic field Polarizing ferrofluid liquid from the suspension in a carrier fluid which nanometers of ferromagnetic particles composed; its carrier fluid is typically organic or aqueous surfactant ferromagnetic particles from the package to prevent due to van der Waals and magnetic force condensation occurs. Despite being called ferrofluid, but they themselves do not show ferromagnetism. This is because in the case where the external magnetic field does not exist, can not maintain a magnetic ferrofluid. In fact, the performance of the ferrofluid paramagnetic, and Due to their high magnetic susceptibility, is generally considered to have "superparamagnetic." produce ferrofluid is difficult in practice, generally require high temperature and electromagnetic floating conditions.
