Abstract of the Disclosure The present invention relates to a device comprising a magnetic circuit. The magnetic circuit is comprised of a first magnetic component which is magnetized in a preferred direction and a second magnetic component whose magnetic coercivity is less than the magnetic coercivity of the first component and which is magnetically biased by the first component. A first unit is provided for inducing a variable magnetic field in the circuit. A second unit is provided for utilizing the energy output. The first component consists essentially of a first alloy which comprises a first amount which comprises at least 90 weight percent of the alloy and which consists of Fe, Cr and Co. The Cr is present in the first alloy in an amount in the range of 20-40 weight percent of the first amount. Co is present in the first alloy in an amount in the range of 3-30 weight percent of the first amount. The second component consists essentially of a second alloy which comprises a second amount which comprises at least 95 weight percent of the alloy and which consists of Fe and Al. The Al is present in the second alloy in an amount in the range of 1.5-18 weight percent of the second amount.
