Schematic diagram of strong magnetic pulling force of neodymium iron boron Many customers have called or contacted our magnet manufacturer through QQ, but since they themselves do not know what specifications and performance of material magnets they need, they directly ask, 'What size of magnet is required to lift multiple and multiple items?'?The magnetic force requirements for magnets vary in different fields and product designs. What the editor wants to say is that the suction force of a magnet is not only related to the size of the magnet, but also to the direction in which the object is attracted,The thicker the iron plate, the greater the suction force, the larger the contact area, and the greater the suction force. The vertical direction is the maximum pulling force direction, and the horizontal direction is the minimum pulling force direction. Therefore, we often translate and push the magnets that are adsorbed together.: 05

The main differences between the vertical and horizontal pulling forces of magnets are as follows 1. Vertical tension refers to the attraction or attraction force of a magnet in the vertical direction, while horizontal tension refers to the attraction force of a magnet in the horizontal direction.2. In the absence of external forces, the maximum vertical pulling force of the magnet is greater than the maximum horizontal pulling force, because gravity enhances the vertical attraction.3. The vertical tensile force rapidly decays as the distance between the magnet and the object increases, but the attenuation of the horizontal tensile force is slower.4. The vertical pulling force is more dependent on the magnetic properties of the magnet itself, while the horizontal pulling force is also related to the magnetic circuit design in addition to the magnetic properties.5. Horizontal tension can continue to transmit motion through mechanism design, but vertical tension can only generate static attraction.6. In a motion system, vertical suction is often used first to obtain fastening, and th: 05

Distance between magnetic switch magnet and reed tube? It is similar to Hall elements, but its principle and properties are different. It is a switch element that uses magnetic field signals to control, without magnetic disconnection, and can be used to detect the state of circuits or mechanical movements. Another type of magnetic switch is the proximity switch, door magnetic switch, or sensing switch in the market. It has a mold and is a standard size plastic shell, Seal the reed tube in a black shell and lead the wire out. Fix the other half of the plastic shell with a magnet on the other end. When the magnet approaches the switch with the wire, it sends a switch signal, which is usually connected at a distance of 10mm.Another type of magnetic switch is to set one or more magnetic spring switches inside a closed metal or plastic tube, and then run the tube through one or more hollow floating balls with ring shaped magnets inside. The fixed ring is used to control the floating ball and magnetic spring switch in relevant positions, making: 05

Where can I buy a countersunk magnet? There are many ways to buy countersunk magnets, whether it's square or rectangular, circular, triangular, or arc-shaped. You can buy them on e-commerce platforms, which is not difficult. If you need to purchase in large quantities, you can choose a magnet manufacturer for customization (more reliable and cost-effective). Of course, Taobao, Pinduoduo, JD.com, and other magnet manufacturers will settle in, Choose the size and price that suits you, and generally recommend a small quantity. For example, if you only need a few to use, you can also call the hardware store nearby to inquire if they have one.There are also many options for choosing magnet manufacturers. On Baidu and Alibaba, there are a lot of options to choose from. You can choose some magnet suppliers with good reputation, long operating time, or closer to you to provide quotes. It is better to provide free samples. Generally, ready-made samples may still require some fees if you need customized samples. For specific inf: 04

Introduction to the specific differences between neodymium iron boron strong magnets N42 and N45 The maximum magnetic energy product standard for N42 material is 40-43MGOe, while the maximum magnetic energy product standard for N45 material is 43-46MGOeDifference in residual magnetism between N42 and N45N42 has 13000GS and N45 has 13300GS residual magnetism, which can be measured using specialized instruments.Is N42 4200gs, and N45 4500gs?No. N42 and N45 are the grades of magnetic materials. 4200GS and 4500GS are magnetic field sizes calculated based on your brand and magnet size. Usually, the larger the magnet area, the lower the surface magnetic dispersion.If the shape and size are the same, statistically speaking, N45 will be about 2% higher than N42 (surface magnetic flux density)N42 and N45 raw material pricesThe price of N42 is 188.5 yuan/kg, and the price of N42 is 195.5 yuan/kg. (For reference only)N42 neodymium iron boron magnet surface magnetic size reference;N42/NI/10 * 10 * 3MM, approximately 2860 Gauss.N42/ZN/75x4x5.8mm, approximately 4000 Gauss.N42H/D6.8 * D3.9 * 0.9: 04

Application of Neodymium Iron Boron Permanent Magnets in New Energy Vehicles New energy vehicles mainly include hybrid electric vehicles and pure electric vehicles. High performance iron iron boron permanent magnet materials are mainly used in driving motors of new energy vehicles. The driving motors suitable for new energy vehicles mainly include permanent magnet synchronous motors, AC asynchronous motors, and switched reluctance motors. Among them, permanent magnet synchronous motors have become mainstream motors due to their wide speed range, high power density, small size, and high efficiency. Neodymium iron boron permanent magnets have the characteristics of high magnetic energy product, high intrinsic coercivity, and high remanence, effectively improving the power density and torque density of motors, and are widely used in permanent magnet motor rotors.EPS (Electric Power Assisted Steering System) is the component that uses the most permanent magnets besides the driving motor (0.25kg/vehicle). The micro motor used in EPS is a permanent magnet motor, whic: 04

Do you know the production process of permanent magnet ferrite? The application of permanent magnet ferrite is very common in daily life, and it is used internally in many motor equipment or electronic products because of its strong magnetism. It is currently a widely used product. Today, I will introduce the production process of permanent magnet ferrite to you.1. Weighing and MixingFerrite raw materials include main raw materials, additives, and fluxes Fe2O3, BaCO3, SrCO3, and CaCO3, which are the main raw materials for ferrite. The weighing process needs to strictly follow the formula, otherwise ideal magnetic properties cannot be obtained.2. GranulationIn order to ensure the smooth progress of the solid-state reaction process, the mixture must be granulated before calcination. During the granulation process, the solution will be sprayed into the mixture. The particle size of granular materials has an impact on aging time.3. Pre sinteringThe purpose of pre sintering is to fully ensure the solid-state reaction of the raw materials. After pre firi: 29

What are the factors that affect the magnetic force of a circular magnet? Magnets are becoming more and more widely used in today's social life. Whether in life or work, we sometimes come into contact with magnets. The development of magnets is so good mainly because they have a wide range of applications. However, we should not only see one side of their halo, but also explore their different aspects. Magnets have some differences, So we should pay attention to these aspects of magnets.Let's start by saying that circular magnets cannot be used in some cases due to their different shapes. This is due to their own reasons, and we cannot change them. However, in some places, they have similarities with other magnets. So what factors are affecting their magnetic performance? The first factor is environmental factors. As circular magnets are mainly presented in a circular shape in front of us, there are certain differences for some special environments. In addition, there is a temperature factor. If the magnet encounters high temperatures, corrosion will: 28
