We suggested the Lambda-like system with two bound degenerated states connected to a continuum state under the external magnetic field. This magnetic field is used to split the ground level into two sublevels by the Zeeman shift and both connection to the continuum state. We show that the electromagnetically induced transparency window can be shifted left or right by changing the sign and magnitude of the magnetic field. Furthermore, the sign and magnitude of the group index can be manipulated simply by changing the sign and magnitude of the magnetic field. It is the advantage to light propagation from the slow to the fast light domain and vice versa.
