1. A magnetic mixing apparatus comprising:
a shaft rotatably coupled to a drive motor unit in such a manner as to penetrate through the drive motor unit;
a first housing provided on an outer side a stirring container in such a manner as to be coupled to one side of the drive motor unit so as to accommodate an upper portion of the shaft;
a second housing provided on another side of the drive motor unit that is opposite to said one side of the drive motor unit such that the drive motor unit is interposed between the first housing and the second housing, the second housing accommodating a lower portion of the shaft;
a rotary rotor coupled to a distal end of the shaft at the stirring container side during a normal operation thereof and including a first permanent magnet;
an impeller unit disposed on an inner side of the stirring container and including a second permanent magnet magnetically coupled to the first permanent magnet during a normal operation thereof;
a height adjustment member connected to the shaft and configured to adjust height of the rotary rotor; and
a handle unit penetrating through the second housing and coupled to the height adjustment member,
wherein the second housing accommodates the height adjustment member, and
wherein the first housing comprises a magnetically separated rotary rotor support unit formed to protrude inwardly from the first housing so as to support, from the downward direction, the rotary rotor, which is downward driven to move downward from the shaft, when there occurs magnetic separation in which a magnetic coupling between the first permanent magnet and the second permanent magnet is released by magnetic deformation of at least one of the first permanent magnet and the second permanent magnet.
