Abstract (en)
[origin: WO2013149681A1] A ball for a sports game comprises a plurality of coils (4a-h) formed by conductors, the conductors of each coil enclosing a coil area. The coils are arranged such that a sum over projected coil areas of all coils of the ball differs by a maximum of 30% between any possible pair of projections along different chosen directions (8), wherein a projected coil area is obtained by a projection of a coil area onto a plane, the projection being performed in parallel to the chosen direction (8).
