摘要： A heat-resistant magnetic domain refined grain-oriented silicon steel, a single-sided surface or a double-sided surface of which has several parallel grooves which are formed in a grooving manner, each groove extends in the width direction of the heat-resistant magnetic domain refined grain-oriented silicon steel, and the several parallel grooves are uniformly distributed along the rolling direction of the heat-resistant magnetic domain refined grain-oriented silicon steel. Each groove which extends in the width direction of the heat-resistant magnetic domain refined grain-oriented silicon steel is formed by splicing several sub-grooves which extend in the width direction of the heat-resistant magnetic domain refined grain-oriented silicon steel. The manufacturing method for a heat-resistant magnetic domain refined grain-oriented silicon steel comprises the step of: forming grooves on a single-sided surface or a double-sided surface of a heat-resistant magnetic domain refined grain-oriented silicon steel in a laser grooving manner, a laser beam of the laser grooving is divided into several sub-beams by a beam splitter, and the several sub-beams form the several sub-grooves which are spliced into the same groove.

摘要： An inductor that is configured to store energy in a magnetic field includes a wire and a core. The wire is configured to deliver electrical current to the inductor to generate the magnetic field. The core is disposed radially about the wire. The core comprises magnetic particles that are suspended in a non-magnetic matrix. The magnetic particles are arranged such that a magnetic permeability of the core increases in a direction that extends radially outward from the wire along a cross-sectional area of the magnetic core from a first region that is adjacent to the wire to a second region that is adjacent to an outer periphery of the magnetic core.
