Claim 0:
1. A coil system, comprising:
a plurality of pairs of planar coils stacked in a vertical direction, each pair of planar coils including:
a first planar coil including a first outer turn; and
a second planar coil including a second outer turn, the second outer turn overlapping the first outer turn and laterally offset from the first outer turn;

a plurality of pairs of thermal conductor tracks stacked in the vertical direction, each pair of thermal conductor tracks including:
a first thermal conductor track; and
a second thermal conductor track overlapping a portion of the first thermal conductor track, laterally offset from the first thermal conductor track, and overlapping the first outer turns of the plurality of pairs of planar coils, wherein:
the plurality of pairs of thermal conductor tracks are DC isolated from the plurality of pairs of planar coils;
the first outer turns and the second outer turns of the plurality of pairs of planar coils form a first comb-like structure; and,
the plurality of pairs of thermal conductor tracks form a second comb-like structure engaged with the first comb-like structure; and,

a wall bounding a portion of a cooling channel, wherein the cooling channel is arranged to receive a cooling fluid and the wall is electrically isolated from the plurality of pairs of planar coils.
