A system for wirelessly charging an electric vehicle comprises a wireless charging coil having a first end, a second end, and a plurality of turns. The first end has a first turn having a first radius r1 and the second end has an Nth turn having an Nth radius rN, rN0 where, Δj,j+1′=rj′−rj+1′ is the distance between adjacent turns, σ is between 0.05% and 0.2%, i is 2 to N; j is 1 to N; and Δ34′ is an ascending distance between the third turn and the fourth turn.
