The reason why neodymium iron boron powerful magnets are known as the magnetic king

Sumitomo Special Metals has successfully developed the powder metallurgy process, while General Motors has successfully developed the melt spraying process, which can prepare neodymium iron boron magnets. This type of magnet is a permanent magnet with magnetic properties second only to absolute zero degree holmium magnets, and is also the most commonly used rare earth magnet. Neodymium iron boron magnets are widely used in electronic products, such as hard drives, mobile phones, headphones, and battery powered tools.Neodymium iron boron magnet is a collective term for powerful magnets, which is a type of artificial permanent magnet. It is currently the strongest permanent magnet and the most cost-effective magnet, and is known as the magnetic king in the magnetic field. It is expected that there will be no alternative magnetic materials to neodymium iron boron magnets in the next 20 years.Neodymium iron boron has extremely high magnetic energy product and coercive force, and the advant

A Brief Discussion on Manufacturers of Neodymium Iron Boron Magnets

1. Analysis of the Principle of Magnetic Field Generation in Strong Neodymium Iron Boron MagnetsStrong neodymium iron boron magnets are the same as electricity, but they cannot be seen or felt clearly. They can only feel magnetism when the iron is close. Magnets are easy to make and have a wide range of applications. We all know that matter has a gravitational field between itself. Similar to a magnetic field, it is a type of field that fills the space around the magnetic poles. The size of the magnetic field can be expressed in terms of the number of imaginary magnetic field lines. The denser the magnetic field lines, the stronger the magnetic field. Conversely, if the magnetic field lines are sparse, the weaker the magnetic field.A powerful magnet in motion will experience a type of Lorentz force on charged particles in the magnetic field. The magnetic field strength of charged particles is distinguished by the strength of their magnetic properties in different magnetic fields. Tesla

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.

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

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

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
