  "textContent": "The present disclosure provides a wireless charging coil, and the wireless charging coil comprises a first coil layer, a second coil layer and a first magnetic material. The second coil layer is stacked in parallel on a surface of the first coil layer to form a stacked structure, and it has a winding path identical to a winding path of the first coil layer. The first magnetic material is disposed on one side of the first coil layer and has a winding path which is different from the winding path of the first coil layer and with said side away from the second coil layer. Currents generated by a power source are evenly distributed in the stack structure to reduce a skin effect when the wireless charging coil is electrically connected to the power source.",
