Influence of temperature on the size of residual magnetic induction of Br which corresponds to the maximum value of magnetic induction of Bmax, is estimated by temperature coefficient of residual magnetic induction (To -
Receive metalplastic magnets, the cook and ceramic-metal, from metal powders which press together with the isolating sheaf and heat to the low temperatures necessary for polymerization of binding substance.
Substituting these values in ratios concrete values In and N, receive different types of magnetic permeability which apply in equipment. Most often use concepts of normal , initial , the maximum max, differential and pulse of magnetic permeability.
Brands of these materials contain the letters Yu and H indicating availability in them of aluminum and nickel. When using of the alloying metals enter additional letters which correspond to these metals into designation of brands, for example, an alloy of system iron-nickel - the aluminum alloyed by cobalt, the YuNDK brands.
Magnetosoft materials with a roundish loop of a hysteresis apply to work in low-frequency magnetic fields. Magnetic materials with a rectangular loop of a hysteresis apply to production of devices of magnetic memory.
