[0002] Halbach magnetic component (also called "Halbach magnet", English name Halbach) is a common magnetic component. By arranging permanent magnets with different magnetization directions in a certain pattern, it can gather magnetic lines of force on one side of the component and weaken the magnetic lines of force on the other side, thereby obtaining a relatively ideal unilateral magnetic field. It is of great significance in engineering and is widely used in industrial fields such as nuclear magnetic resonance, magnetic levitation, permanent magnet special motors, etc.

[0003] Currently, some Halbach magnetic assemblies are formed by bonding, that is, bonding multiple magnets into a Halbach magnetic assembly. During the bonding process, due to the magnetic force between the magnets, uneven glue adhesion will occur, affecting the quality of the final product. Although there are currently technical solutions for using magnetic parts to balance the magnetic force between the magnets in the Halbach magnetic assembly, the effect of improving glue adhesion is not ideal.

[0004] Therefore, in the process of bonding the magnets, how to optimize and balance the magnetic forces between the magnets to facilitate the adhesion of glue between the magnets remains to be solved. Utility Model Content

[0007] The magnetic assembly includes a first magnet, a second magnet, a third magnet and a fourth magnet arranged side by side from left to right, and the magnetization directions are upward, leftward, downward and rightward in sequence;

[0008] The first magnetic block is located below the first magnet, with the magnetization direction upward;

[0009] The second magnetic block is located on the right side below the third magnet, with the magnetization direction downward;

[0010] The third magnetic block is located on the left side below the fourth magnet, close to the right side of the second magnetic block, and the magnetization direction is upward;

[0011] The magnetic conductive block is arranged on one side of the second magnetic block and the third magnetic block close to the magnetic assembly;

[0012] The fourth magnetic block, the fifth magnetic block and the sixth magnetic block are arranged outside the range below the magnetic assembly at intervals, and the magnetization directions are downward, upward and downward in sequence.

[0013] Furthermore, the magnetic conductive block is made of steel.

[0014] Furthermore, a spacer block made of non-magnetic material is arranged between the fifth magnetic block and the sixth magnetic block.

[0015] Furthermore, the first magnetic block is located in the center below the first magnet.

[0016] Furthermore, the magnetization direction is the direction of the line from the S pole to the N pole.

[0017] After adopting the above scheme, the beneficial effects of the utility model are: the first magnetic block is located below the first magnet, and the magnetization direction is upward; the second magnetic block is located below the right side of the third magnet, and the magnetization direction is downward; the third magnetic block is located below the left side of the fourth magnet, close to the right side of the second magnetic block, and the magnetization direction is upward; the magnetic conductive block is arranged on the side of the second magnetic block and the third magnetic block close to the magnetic assembly; the fourth magnetic block, the fifth magnetic block and the sixth magnetic block are arranged outside the range below the magnetic assembly at intervals, and the magnetization directions are downward, upward and downward respectively, so as to balance the magnetic force between the first magnet, the second magnet, the third magnet and the fourth magnet, so that in the process of bonding the first magnet, the second magnet, the third magnet and the fourth magnet into an integrated Halbach magnetic assembly, the glue distribution can be more even, so as to improve the product quality of the Halbach magnetic assembly.
