Abstract
A magnetic device includes a T-shaped magnetic core, a wire coil and a magnetic body. The T-shaped magnetic core includes a base and a pillar, and is made of an annealed soft magnetic metal material, a core loss P(mW/cm) of the T-shaped magnetic core satisfying: 0.64×f×B≦P≦7.26×f×B, where f (kHz) represents a frequency of a magnetic field applied to the T-shaped magnetic core, and Bm (kGauss) represents the operating magnetic flux density of the magnetic field at the frequency. The magnetic body fully covers the pillar, any part of the base that is located above the bottom surface of the base, and any part of the wire coil that is located directly above the top surface of the base.
