We have studied the domain wall longitudinal propagation and its dynamics under the influence of transverse magnetic field in thin magnetic wires. A different behavior was observed for strong and weak transverse fields. In weak transverse field H(t), the domain wall dynamics depends on the direction of H(t). Transverse field applied in one direction increases the Walker limit and shifts the existence of transverse domain wall to higher axial field. Transverse magnetic field applied in opposite direction decreases the Walker limit and favors vortex domain wall even at low fields. Different behavior was obtained in strong transverse field which speeds up the domain wall velocity to its saturation value of 9 km/s independently on the orientation of transverse field.
