A model (with no free parameters) for the current‐driven motion of magnetic bubble lattices is developed, consisting of massless damped elements (bubbles) connected by linear springs (representing the bubble‐bubble interaction). For the specific system considered, the model yields a saturation velocity of about 1 m/sec, in agreement with experiment. The variation of bubble diameter is not explicitly computed; treatment of this additional degree of freedom should produce a still more realistic model.
