Cylinder Halbach Array

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.

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.

We have strong sintered AlNiCo permanent magnet production scale, can produce the performance of Alnico2-8 grades. And annual output nearly 800 tons. AlNiCo magnet is suitable for producing complex, light, thin, and small products, and is widely used in instrumentation, communications, magnetoelectric switches, and various sensors. AlNiCo products are mainly used in automotive parts, instrumentation, electroacoustics, motors, nuclear power, teaching, aerospace and other fields. It has the characteristics of low temperature coefficient, high temperature resistance, humidity resistance, not easy to oxidize and good working stability.

Smco magnet, samarium cobalt magnet: Iso/ts16949/iso9001/iso14001 Product description Smco magnet, samarium cobalt magnet: Iso/ts16949/iso9001/iso14001 Our smco shape: Smco arc and segment magnet Smco block magnet Smco ring magnet Smco disc magnet and cylinder magnet Irregular smco magnet Our smco property: Smco5, sm2co17, yx16, yx20, yx20, yx22, yx24, yx20s, yx22s; yxg24h, yxg26h, yxg28h, yxg30h; yxg24, yxg26, yxg28, yxg30; yxg26m, yxg28m, yxg30m; yxg28l, yxg30l; Samarium cobalt (smco) magnets, the second generation of rare earth magnet material, have high magnetic properties, excellent thermal stability and resistant to corrosion. Compared with ndfeb, it needn't to be coated. It can typically be used up to 300 'c. Therefore, it is used in those fields, that applications demand resistance to wide range temperature and environments. How ever, it is extremely brittle and the cost is relatively expensive. Sintered smco magnets usually divided into smco5 and sm2co17 according to the components. Smco magnets have following applications: Holding systems requiring very high holding forces, High field yoke magnets, High performance stepper, Dc, servo, linear, and voice coil motors, Magnetic bearings, magnetic couplings, Loudspeakers, halbach arrays, headphones, Microphones, magnetic separation, instrumentation, switches, relays, magnetic resonance, sputtering, Vacuum deposition, charged particle beam guidance, particle accelerators, undulators, wigglers, and others.
