Abstract
Using a discrete model of two-dimensional easy-plane classical ferromagnets , we propose that a rotating magnetic field in the easy plane can switch a vortex from one polarization to the opposite one if the amplitude exceeds a threshold value, but the backward process does not occur. Such switches ar e indeed observed in computer simulations.
