Cette petite girouette a, ainsi que la petite girouette b placée symétriquement de l'autre côté du cylindre, indiquaient la direction du vent local. Lorsque, la soufflerie fonctionnant, le cylindre était immobile, les deux girouettes se plaçaient sensiblement selon la direction du courant d'air (symétriquement). Mais lorsque le cylindre tournait, les deux girouettes étaient déviées vers la gauche ou la droite du courant d'air, ce qui révélait l'effet Magnus.
On remarque ici la soufflerie centrifuge utilisée par Magnus pour ses expériences. Cette soufflerie était entraînée par le disque à manivelle placé à sa droite.
Ce disque à manivelle mettait en rotation le cylindre.
