The magnetic properties of ternary alloys of iron,silicon,and cobalt have been measured,and the relation of these properties to their respective concentration have also been investigated. Those alloys containing about 9∼13%Si, about 13∼20%Co show the permeability maximum region and their representative alloy contains about 10%Si,about 15%Co. Some of its magnetic properties are as follows ; the initial permeability, 470,the maximum permeability,21700,the magnetic hysteresis-loss,330 erg/cm3/cycle,the coercive force,0.22 Oersteds and the residual induction,4650 Gausses at maximum induction,5000 Gausses.
