Abstract: An electroplating method for producing magnetic conducting materials, such as charging coils used in induction charging of electronic devices, comprising the following steps: constant tension releasing conducting material, such as cooper wire, the conducting material then undergo these process: alkaline washing then clean water washing, degreasing, acidic washing then clean water washing, continuous plating, clean water washing, drying, infrared measuring the diameter and retracting the conducting material. The method allows electroplating preparation of uniform and dense distribution of iron and nickel coating layer on the surface of conducting material, wherein, the thickness of the coating layer is 2˜10 μm. Since the conducting material is non-magnetic, but through the electroplating preparation, the entire charging coil is magnetized to become magnetic material, which when used during induction charging provides the coil with electro resistance that reducing high-frequency skin effect and improving electro induction.
