A magnetic coupling assembly and a magnetic coupling stirrer mixer are disclosed. The magnetic coupling assembly includes a rotary round disk, a magnetor assembly, a container, and a stirring member,wherein the magnetor assembly includes two north-pole (N) magnetors arranged in one side of the rotary disk and two south-pole (S) magnetors which are arranged in the other side of the rotary disk; the stirring member is axially magnetized with an N pole formed on one end and a S pole formed on the other end; the stirring member is arranged in content in the container. The two north-pole (N) magnetors are coupled to the S pole while the two south-pole (S) magnetors are coupled to the N pole. Due to the four-corner sealing structure, the stirring member is fixed at a single and unique positionwithout deflection and deformation, so that when the round disk rotates, the stirring member is fixed by the 2N=2S four corner magentic force and rotates in order to stir the content.
