How to Use Magnetic Trap

   The minimum magnitude of the magnetic field can be realized with the "atom microchip".[1] One of the first microchip atomic traps is shown on the right. The Z-shaped conductor (actually the golden Z-shaped strip painted on the Si surface) is placed into the uniform magnetic field (the field's source is not shown in the figure). Only atoms with positive spin-field energy were trapped. magnetic trap To prevent the mixing of spin states, the external magnetic field was inclined in the plane of the chip, providing the adiabatic rotation of the spin at the movement of the atom. In the first approximation, magnitude (but not orientation) of the magnetic field is responsible for effective energy of the trapped atom. The chip shown is 2 cm x 2 cm; this size was chosen for ease in manufacture. In principle, the size of such microchip traps can be drastically reduced. An array of such traps can be manufactured with conventional lithographic methods; such an array is considered a prototype of a q-bit memory cell for the quantum computer. Ways of transferring atoms and/or q-bits between traps are under development; the adiabatic optical (with off-resonant frequencies) and/or the electrical control (with additional electrodes) is assumed.

Performance guarantee magnet control from raw material production process

1, according to the business of manufacturing high-end or mid-range or low-grade sintered NdFeB requirements, in accordance with national standards for raw ingredients to buy raw materials. 2, advanced production technology directly determines the performance quality of the magnet. The most advanced technology is scale ingot (SC) technology, hydrogen broken (HD) technology and jet mill (JM) technology. Small capacity vacuum induction melting furnace (10kg, 25kg, 50kg) has been a large capacity (100kg, 200kg, 600kg, 800kg) vacuum induction furnace replaced. SC (Strip Casting) quick-setting slab technology has gradually replaced the large slabs (thickness 20-40mm cooling direction than ingot), hydrogen broken (HD) technology and jet mill (JM) to replace the jaw crusher, disk mill, ball mill (wet milling) to ensure the uniformity of the powder, and is conducive to liquid-phase sintering and grain refinement. 3, the magnetic field orientation, our country is the only country two-step pressing of perpendicular alignment with a small pressure molding, and finally the use of quasi-isostatic pressing, which is one of the sintered NdFeB industry's most important features . 4, and monitor the quality of the production process is very important, we can control by SC thickness measurement and JM powder particle size distribution testing methods. Quality products are dependent on control of the production process, but customers will be very confused, how to judge the performance of the product I buy it? China Institute of Metrology has developed a variety of types of permanent magnetic materials technology magnetic parameters measuring instruments. Pulsed magnetic field magnetometer (PFM) is a testing ultra-high coercivity permanent magnet test equipment, mainly in order to adapt to the field of electric vehicles and large-scale permanent magnet motor needs high coercivity neodymium cylinder magnets. Customers can magnet parameters Br (remanence), Hcb (coercivity), Hcj (intrinsic coercivity), (BH) max (maximum energy product) Selected NdFeB grades they need, while four That argument is to determine the product is not manufactured according to customer requirements of the standard.

The magnetic filter installation:

The magnetic grate separator flange connected to the interface with the slurry outlet line, so that a uniform slurry flow from the filter before, after a period of time to try to determine the cleaning cycle.
When cleanup first loosen the clamping screw cover, remove the casing cover member, and then out of the magnet, the iron adsorbed on the sleeve impurities will automatically fall off. First the cannula into the barrel after a clean installation, tighten the clamp screw, then put the lid magnet inserted into the tube, you can continue to use.

The magnetic filter works:

In the liquid slurry transportation process, the slurry through a filter, that is a powerful magnet magnetic drawers action, the slurry of iron impurities are adsorbed on the magnet sleeve, the elimination of slurry of iron impurities, guarantee the next process can effectively control the iron impurities.

Magnetic filter use:

inline magnetic filter is mainly used to remove liquid slurry ferromagnetic impurities, widely used in chemical, pharmaceutical, pigments, dyes, food, metallurgy, ceramics and other industries, this product has a strong magnetic grates force, in addition to the effect of good iron, iron cleanup crumbs and easy.

Magnetic grating and grate magnets act?

   By recording heads in magnetic tape Magnetic Grid design: an important feature of the magnetic grid is the magneticgrid ruler and head in contact state. The working principle of the magnetic grid is a magnetoelectric conversion, in order to ensure that the head is the output signal amplitude stability, taking into account the air gap reluctance,are not allowed to exist and variable between the magnetic grid ruler and thehead, it is best to contact. This belt type magnetic grid work head is pressed into the tape, so instant with face some irregularities, the head and the tapecan also good contact. About 0.01mm of the gap between the linearmagnetic magnetic grating ruler and head, because the assembly andadjustment can not reach the ideal state, so the actual line type magnetic grid is quasi contact state. Another important feature of the magnetic grid ismagnetic grating ruler is in a tension state.) on record magnetic wave interval strictly equal a process known as magnetic recording. Magnetic taperecording has good magnetic wave called a magnetic ruler. Magnetic gratingruler adjacent gate wave interval distance is called the magnetic gratingwavelength, also known as the magnetic grid pitch (pitch). Magnetic grating ruler is the base element magnetic grating digital readout system. Obviously,the wavelength is the magnetic grating length measuring unit. Any of the measured length corresponding to the number of available wavelength andto represent the magnetic grid. Made of hard alloy magnetic grating rulerbodies can meet certain requirements. Can also be made of magneticmaterial surface coated with a layer of hard magnetic alloys. Made of hardalloy magnetic material of magnetic railings ruler performance have the following requirements: good magnetic materials have larger remanence andcoercivity, namely loop material should be a big fat. Good magnetic uniformmagnetic materials can be more uniform as possible, in order to ensure theequal amplitude recorded magnetic remanence, otherwise it will affect the accuracy of the magnetic grid. Magnetic stability of the composite goodrecording magnetic remanence intensity after should not have performancealong with the extension of time and quickly weakened. Materials with good mechanical properties should have high mechanical      strength, hardness andwear resistance, easy machining and is not easily affected by external temperature and humidity. Frequency characteristics of certain can guarantee in the remanent intensity the certain requirements of the record on the desired frequency (wavelength) of the magnetic wave. Hard alloy is commonly used in Cu-Ni-Fe alloy or Fe-Cr-Co alloy; magnetic coating of commonly used components are Ni, Co, P.
