WIPO Patent Application WO/2024/024121
Kind Code:
A1
Abstract:
This coil (100A) comprises an electric wire (1) that is wound around a center axis (2) once or multiple times in a spiral manner. The electric wire (1) includes a conductor (10) having a long narrow cross-sectional shape (11) in a plane that includes the center axis (2). The cross-sectional shape (11) is curved so that a first end (12) and a second end (13) in the longitudinal direction are spaced away from the center axis (2). Consequently, loss is reduced in the coil comprising the electric wire that is wound once or multiple times in a spiral manner.
