Abstract: A coil for forming an induced magnetic field may include a first coil bundle formed of a first conducting wire wound in a first direction, the first coil bundle having an inner space of a prescribed inner width, a second coil bundle formed of a second conducting wire wound in a second direction, the second coil bundle having a prescribed outer width that is smaller than the inner width of the first coil bundle, and a connector that electrically connects the first conducting wire and the second conducting wire to each other. The second coil bundle may be provided in the inner space of the first coil bundle. The conducting wires of the first and second coil bundles may be wound in opposite directions and gaps between coil bundles may be changed. Accordingly, the magnetic field can be more evenly distributed in a wider area while maintaining a constant inductance.

Abstract translation: 用于形成感应磁场的线圈可以包括由沿第一方向缠绕的第一导线形成的第一线圈束，第一线圈束具有规定的内部宽度的内部空间，第二线圈束由第二导线 在第二方向上卷绕，第二线圈束具有比第一线圈束的内部宽度小的规定的外部宽度，以及将第一导体线和第二导线彼此电连接的连接器。 第二线圈束可以设置在第一线圈束的内部空间中。 第一和第二线圈束的导线可以沿相反方向缠绕，并且可以改变线圈束之间的间隙。 因此，磁场可以更均匀地分布在更宽的区域中，同时保持恒定的电感。
