    摘要: A powder magnetic core having reduced core losses and increased mechanical strength is provided at low costs. The core is obtained by compressing a ferromagnetic metal powder and an insulating agent and then annealing the compressed body. The ferromagnetic metal powder is made up of a substantially spherical form of ferromagnetic metal particles containing Fe, Al and Si. The core has a permeability of at least 50 at 100 kHz, a core loss of up to 450 kW/m.sup.3 at 100 kHz in an applied magnetic field of 100 mT, and a core loss of up to 300 kW/m.sup.3 at 25 kHz in an applied magnetic field of 200 mT.
