Claim 16:
17. A method of producing a coil system, comprising:
producing a plurality of pairs of planar coils, 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 overlapping the first outer turn and laterally offset from the first outer turn;

stacking the plurality of pairs of planar coils in a vertical direction;
forming a first comb-like structure with the first outer turns and the second outer turns of the plurality of pairs of planar coils;
producing a plurality of pairs of thermal conductor tracks, 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;

stacking the plurality of pairs of thermal conductor tracks in the vertical direction;
forming a second comb-like structure with the plurality of pairs of thermal conductor tracks; and,
engaging the first comb-like structure with the second comb-like structure;
wherein:
for a first pair of planar coils of the plurality of pairs of planar coils:
the first planar coil is arranged in a first configuration; and
the second planar coil is arranged in a second configuration, the second configuration created by rotating the first configuration 180 degrees around a vertical central axis; and

for a second pair of planar coils of the plurality of pairs of planar coils, stacked on the first pair of planar coils:
the first planar coil is arranged in a third configuration, the third configuration created by mirroring the first configuration on the vertical central axis; and
the second planar coil is arranged in a fourth configuration, the fourth configuration created by mirroring the second configuration on the vertical central axis.
