Embodiment
Referring to Fig. 1, Fig. 1 is a kind of flow chart of the preparation method of magnetic orientation pattern provided in an embodiment of the present invention, this
The preparation method of embodiment magnetic orientation pattern includes：
S101：The first magnet and the second magnet are combined, to expand the first magnet by magnetic coupling mode using the second magnet
Leaning magnetic field region.
When in the absence of the second magnet, what the magnetic circuit of the first magnet was to determine, Fig. 2 is referred to, Fig. 2 is the first single magnetic
The magnetic line of force of body moves towards schematic diagram, figure it is seen that the magnetic line of force has no the effect of obvious three-dimensional dynamic circle, the magnetic line of force
Graded is few.
After the second magnet is combined, due to the induction coupling between the first magnet and the second magnets magnetic fields so that the
The leaning magnetic field region of one magnet expands.Referring to Fig. 3 and Fig. 4, Fig. 3 is the first magnet and a kind of knot of combination of the second magnet
Structure schematic diagram, wherein, the first magnet 1 is stacked and placed on the top of the second magnet 2, Fig. 4 be Fig. 3 combination under magnetic field the magnetic line of force
Move towards schematic diagram, from fig. 4, it can be seen that between the first magnet and the second magnet after induction coupling, the magnetic line of force occurs substantive
Change, forms large-scale magnetic line of force gradient performance, and cause the stereoeffect of a wide range of dynamic circle in overlapping portion.
First magnetic field and the second magnet are all magnets, can be permanent magnet or soft magnetic bodies, for example：First magnetic
Body is permanent magnet, and the second magnet is soft magnetic bodies；Or first magnetic field and the second magnet be all permanent magnet；Or first magnetic field and
Two magnets are all soft magnetic fields.Fixed when needing to form bulk pattern, during the pattern of peripheral pattern dynamic change, the first magnet can be with
Using permanent magnet, the second magnet can use soft magnetic bodies, in this way, can form the magnetic field of a wide range of dynamic change.
Combining the mode of the first magnet and the second magnet has many kinds, such as combination stacked on top of one another, left and right stacked combination, flat
Paving combination etc..In actual applications, can be according to different magnetic materials, different strong and weak magnetic fields, magnet of different shapes, difference
