Halbach array is a special arrangement of permanent magnets that augments the magnetic field on one side of the array while cancelling the field to near zero on the other side.[1] This is achieved by having a spatially rotating pattern of magnetisation.
The rotating pattern of permanent magnets (on the front face; on the left, up, right, down) can be continued indefinitely and have the same effect. The effect of this arrangement is roughly similar to many horseshoe magnets placed adjacent to each other, with similar poles touching.
As we all know it is rather hard to achieve single side magnetism, for all magnets are with two oppisite magnetic poles, so we have to achieve it by some special design and structure. The structure is based on some particular magnetic array to achieve concentration of magnetic force, it will get better penetration in compare with normal two poles magnets. Halbach array is a good solution.

Custom Neodymium Magnets Components Halbach Array Ring Neodymium Magnetic The Halbach Array is entirely composed of rare earth permanent magnet materials. By arranging the permanent magnets with different magnetization directions according to a certain rule, the magnetic field lines can be concentrated on one side of the magnet, and the magnetic field lines can be weakened on the other side, thereby obtaining an ideal unilateral magnetic field. This is of great significance in engineering. With excellent magnetic field distribution characteristics, Halbach Arrays are widely used in industrial fields such as nuclear magnetic resonance, magnetic levitation, and permanent magnet motors.

Description : Plastic-bonded magnets are particle composites with permanent-magnet powder embedded in a plastic binder. Hard ferrite (HF), various SmCo and NdFeB powders and, to a very little extent, AINiCo alloys are used as magnetic powder. For embedding the magnetic particles, thermoplastic binders as, for instance, polyamide (PA) or polyphenyl sulfide (PPS) and duroplasts like epoxy resins are used. Depending on the material composition and production process, isotropic and anisotropic magnets with differing magnetic and mechanical specifications are available. Since not only the type of magnet or plastic material, but the filling and alignment degree, too, determine the composite`s properties, the outcome is widely varying magnetic parameters and an outstanding variety in types and shapes.
