FIG. 8 is a schematic view illustrating cross sections of a first coil and a second coil of a coil unit according to another embodiment of the disclosure. FIG. 9 is a perspective view illustrating cross sections of a first coil and a second coil of a coil unit according to another embodiment of the disclosure.
Referring to FIGS. 8 and 9, a coil unit 200 within an electronic device may include a first coil 210 by a first number or a second number of turns and a second coil 220 by a third number of turns. The configuration of the first coil 210 in FIGS. 8 and 9 may be at least partially the same as the configuration of the first coil 210 of the coil unit 200 in FIG. 2 and FIGS. 3A and 3B, and the configuration of the first coil 210 in FIGS. 8 and 9 may be at least partially the same as the configuration of the second coil 220 in FIG. 2.
In FIG. 8, “X” in a 2-axis orthogonal coordinate system may indicate the radial direction of the coil unit 200, and “Z” may indicate the thickness direction of the coil unit 200. In an embodiment, “Z” may indicate a first direction (+Z) or a second direction (?Z). FIGS. 8 and 9 are different from FIGS. 5 to 7 in terms of the arrangement relationship of the first coil 210 and the second coil 220. Thus, descriptions will be focused on a different configuration, and a redundant description may be omitted.
