Abstract: We show that a spontaneous electric current is induced in a nanoscale conducting ring just by attaching three ferromagnets. The current is a direct consequence of the noncommutativity of the spin algebra, and is proportional to the noncoplanarity (chirality) of the magnetization vectors. The spontaneous current gives a natural explanation to the chirality-driven anomalous Hall effect.
