Abstract: The reaction rate of non-leptonic quark weak interaction and the bulk viscosity of quark matter in the magnetic field are investigated. The approximation method for calculating the reaction rate in a weak magnetic field is improved, the results of the reaction rate of non-leptonic process and the bulk viscosity of quark matter are given. It is shown that the relationship between the bulk viscosity and the temperature in the weak magnetic field case is the same as that in the zero magnetic field case, but the magnitude of bulk viscosity is affected by the strength of the magnetic field.
