Problems solved by technology

[0004] However, most of the enameled wires of wireless charging coils in the prior art are copper cores or copper-clad aluminum cores plus an insulating layer structure, such as Chinese patent 201020632225.6, or only a certain layer of enameled wire is improved, such as 201810903736.8. The magnetoelectric conversion efficiency of the wireless charging coil cannot be fully improved, and it has low magnetostriction and potential safety hazards
