We study the control of the pulse propagation dynamic and two-channel magneto-optic switching in a degenerate Y-type four-level atomic medium under an external magnetic field and relative phase by numerical simulations. It shows that transitions between the transparency and absorption regimes of the probe pulse depend on turning on or off the magnetic field in different frequency and phase domains. We can effortlessly transform single to double transparency windows, and vice versa, by adjusting the strength or direction of the external magnetic field, thereby obtaining pulse propagates with a stable shape and creating single/two-channel switching for the probe pulse. Furthermore, the relative phase significantly influences the probe absorption spectrum and can effectively modify the pulse propagation dynamic. In particular, switching status can be anti-synchronous or synchronous by modulating the magnetic field. The obtained results from the investigated model may be helpful for applications in multi-channel magneto-optic switching and storage for optical communications.
