Abstract
A coil structure includes a coil set including a first coil and a second coil. The first coil and the second coil are wound to form an annular area. A first end of the first coil and a first end of the second coil are close to an inner ring of the annular area. A second end of the first coil and a second end of the second coil are close to an outer ring of the annular area. The first end of the first coil is electrically connected to the first end of the second coil. A first projection-of the first coil on a plane perpendicular to an axial direction of the coil structure and a second projection of the second coil on the plane are mirror-symmetrical to each other.
