    Abstract: Disclosed is a modified magnetic coil structure. A substrate, at least one circuit pattern layer and a permeability enforced ring are included. The substrate is formed of an electrical insulation material, and has a through hole. The circuit pattern layer is formed of an electrically conductive material and configured in the substrate to surround but not contact the through hole. The permeability enforced ring is formed of a high permeability material and provided in the through hole so as to fully cover a sidewall of the through hole. The permeability enforced ring and the substrate form two co-planes in an upper horizontal plane and a lower horizontal plane of the modified magnetic coil structure, respectively. Therefore, the present invention employs the permeability enforced ring to greatly increase magnetic flux density to form a high permeability device, thereby improving the electromagnetic effect and properties of the magnetic coil.

    Abstract: Disclosed is a magnetic excitation coil structure including a magnetic coil sheet formed of a thin film and rolled as a cylindrical body with a hollow hole, and an insulation layer covering the outer surface of the cylindrical body formed by the magnetic coil sheet for protection. The magnetic coil sheet includes a flexible substrate, a dielectric layer attached to the flexible substrate, and a plurality of patterned circuit layers embedded in the flexible substrate and in contact with the dielectric layer. Each patterned circuit layer is separate, and the upper surfaces of the patterned circuit layers and the upper surface of the flexible substrate form a co-plane. The magnetic coil structure provides an electrical function of coil, which is enhanced by the patterned circuit layer due to its high aspect ratio of the electrical circuit, thereby greatly increasing the whole magnetic flux and electromagnetic effect.
