Single - sided magnet and double - sided magnet

Magnets have two poles, but in some working positions need a single-sided pole magnet, so you need to use iron to cover a magnet, so that the iron covered that side of the magnetic shield, through the refraction of the iron to the other side of the magnet, so that the magnetic enhancement of the other side of the magnet, such a magnet is referred to as single-sided magnetic or single-sided magnet, there is no real single-sided magnet. Difference: is that one side of the magnet magnetic strong, one side of the remaining weak magnetic but does not mean no. A double-sided magnet is magnetically equal in both directions. The material used for single-sided magnet is generally curved iron sheet, and the shape of the strong magnet used for single-sided magnet is generally circular shape. What is the use of single-sided magnet? (1) The printed matter industry is widely used in the gift packaging box, mobile phone packaging box, tobacco and alcohol packaging box, mobile phone packaging box, MP3 packaging box, moon cake packaging box and other products have the existence of single-sided magnets. (2) The leather goods industry is widely used, bags, briefcases, travel bags, mobile phone covers, wallets and other leather goods have the existence of single-sided magnets. (3) Stationery industry is widely used, notebook, whiteboard buckle, folder, magnetic nameplate and so on have the existence of single-sided magnets. Characteristic of magnet Permanent magnet material is based on intermetallic ndfeb. Ndfeb has very high magnetic energy product and strength. At the same time, the advantages of high energy density make NdFeb permanent magnet material widely used in modern industry and electronic technology, so as to make it possible to miniaturize, lightweight and thin equipment such as instruments, electroacoustic motors and magnetic separation and magnetization. Material features: the advantages of Ndfeb are cost-effective, with good mechanical characteristics; The shortcoming lies in the low temperature point of Curie, poor temperature characteristics, and easy to powder corrosion, must be improved by adjusting its chemical composition and surface treatment method, in order to meet the requirements of practical application. The performance comparison of ferrite and NdFeb magnet? Appearance: Loose ferrite and no metallic luster, generally not electroplated, usually black. Ndfeb are basically electroplated, otherwise it is easy to rust. The surface has a silver-white metallic luster. Magnetic: according to the information that ferrite magnetic force is usually 800-1000 Gauss, density is 5(g/cm 3). And in the state of bare magnetic, Ndfeb magnetic force can reach about 3500 gauss. The density was 7.5(g/cm 3). Performance: ferrite temperature resistance and stability are very good, compared with the ordinary temperature resistance of NdFeb only 80℃. And it's cheap. Ndfeb; Ndfeb has the characteristics of small size, light weight and strong magnetism, magnetism and ferrite is not a level at all. Price: ferrite is usually cheap, many are calculated according to the piece, the price and ferrite shape, size, processing difficulty have an impact. Ndfeb: Now the price of NdFeb changes almost every day, depending on the brand and special requirements you need to use.

magnet with one edge for packing boxes

technical subject

what is a single pole magnet

[0001] The utility model is related to a unique single-sided magnet for a packing package that is frequently used in everyday life for present packaging.

Planning strategy

[0002] A single-sided magnet is one that only has one magnetic side and one feeble magnetic side. In order to shield and reflect the magnetic power of the wrapped side into the other side, one side of the double-sided magnet is wrapped in carefully treated galvanized iron sheet. In the packing box, present box magnets must be magnetic on one side. The other side of the magnetic will be increased.

Object-oriented material

[0003] The utility model’s technological challenge is to offer a single-sided magnet for packing boxes that is easy to assemble, affordable, and practical to use.

[0004] The primary characteristic of the utilitarian model is that it is made up of an iron shell, a ndFeb magnet, and a box lid. The utilitarian variant is distinguished by an iron shell that is positioned in the middle of the bottom end of the box cover, is inlaid into the box cover, and is home to a NdFeb magnet.

The utility model’s benefits include its straightforward construction, cheap price, and practical use.

Contains illustrations

[0006] FIG. 1 displays the particular application of the utility model’s product structure schematic.

[0007] The sketches that are attached and the utility model are further described.

[0008] The box cover 3, NdFeb magnet 2, and iron casing I make up the single-sided magnet for the packing box in Figure 1. A NdFeb magnet 2 is positioned inside an iron shell I, which is positioned in the middle of the bottom end of the box cover 3. The iron shell I is embedded in the box cover I.

[0009] Since the magnet on the gift box only requires one side of the magnetic material, using single-sided magnetic will significantly cut costs and conserve magnetic materials. For example, whereas a packaging box containing two NdFeB magnets with a diameter of 10*2 each may require 0.2 Yuan, single-sided magnetic would only require 0.1 Yuan per magnet. Because the real diameter and thickness of the magnet are unaffected by the magnetic force and the iron case’s thickness is Imm while the magnet’s diameter is 8 thickness 1, the cost of the packing box and magnet materials can be reduced.

single pole magnet value

1. Box cover (3), NdFeb magnet (2), and iron casing make up a single-sided magnet for packing boxes (I). Its distinctive features include the arrangement of an iron shell (I) in the middle of the bottom end of the box cover (3), embedded within the box cover (I), and positioned within the iron

The specific difference between single-sided magnet and double-sided magnet

which is introduced because some occasions only need one side to have magnetism, the other side if there is magnetic will cause damage or interference to the product itself, so this time you need to use single-sided magnet.

Like some occasions such as the magnet on the box, only one side of the magnetic, the other side is optional, magnetic is useless, so the use of single-side magnetic will greatly reduce the cost and save magnetic materials.

In the magnet industry, single-sided magnetic and double-sided magnetic are essentially the same, both ndfeb magnets, but the single-sided magnet is relatively low in cost. It is composed of an iron shell assembled with a magnet. In this way, the magnetic side of the wrapped will be shielded, the magnetic force will be refracted to the other side, and the magnetic side will be enhanced. The double-sided magnet is an ordinary circular magnet that is not wrapped.

Single-sided magnet double-sided magnet price comparison

In terms of price, the same specification of single-sided magnet than double-sided magnet is lower, the magnetic strength of the single side is not much different.

is there such thing as a single pole magnet?

The magnetic refraction of single-sided magnet is like the refraction of satellite pan to signal or flashlight lamp pan to light, its refraction effect is mainly determined by the following three aspects: 1. Materials: The choice of materials and thickness, as well as magnets and material spacing has a close relationship. Pure iron sheet is prone to magnetic leakage, and the refraction will be enhanced after special treatment, but the 100% shielded material has not been studied, but the material effect of different manufacturers is also different. 2 Angle: According to the principle of refraction, arc material effect is the best, right Angle material refraction loss is larger. 3. Space: Magnetic lines of force are like cell phone signals in the air. They need space to be refracted. If the torch lamp pot is completely wrapped in the lamp cannon, the use effect is definitely not good, because a lot of light refraction is lost. How to use the above principles, the best effect of magnetic enhancement, is a lot of parameters between the best problem, so in the field of packaging boxes and bags will greatly reduce the production cost and save magnetic materials.

1. Magnetic difference: in the case of the same specification, the magnetic force of single-sided magnet is lower than that of double-sided magnet.

2. In terms of wrapping, single-sided magnet is a combination of an iron shell assembling a magnet, so that the magnetic side of the wrapped is shielded and the magnetic force is refracted to the other side to enhance the magnetism of the other side. A double-sided magnet is just an ordinary circular magnet, and there is no wrapping.

3. In terms of use, single-sided magnet can be applied in mobile phone vibration, hard disk drive voice coil, power tools, frequency conversion air conditioning engine, etc., while double-sided magnet is applied in sound components, magnetic adsorption components, magnetic separator, magnetizers, etc.

Applications of single-sided magnets

Many people on the market for the structure of the single-sided magnet is very confused, in fact, single-sided magnet refers to a magnetic side, the other side of the magnetic weak magnet, the method is to use a special treatment of galvanized iron sheet will be double-sided magnet side of the package, so that the wrapped side of the magnetic shield, magnetic refraction to the other side, the other side of the magnetic will be enhanced. If some occasions only need a magnetic side, if the other side of the magnetic will cause damage or interference; In some cases, such as the magnet on the packaging box, only one side needs to be magnetic, the other side is optional, motor speed control with single pole magnet, magnetic is useless, so the use of single-side magnetic will greatly reduce the cost and save magnetic materials. Here Hefeng magnet will teach you some knowledge about one – sided magnetism.

The refraction effect of single-sided magnet is mainly determined by the following three aspects:

1. Material: Material selection and thickness, as well as the distance between the magnet and the material has a close relationship. Pure iron sheet is easy to leak magnetic, after special treatment of refraction will be enhanced, but 100% shielding material has not been studied, but different manufacturers do material effect is also different.

2 Angle: According to the principle of refraction, arc material effect is the best, right Angle material refraction loss is larger.

3. Space: Magnetic lines of force are like cell phone signals in the air. They need space to be refracted. If the torch lamp pot is completely wrapped in the lamp cannon, the use effect is definitely not good, because a lot of light refraction is lost.

Single-side magnet application industry focuses on: mooncake box, printing and packaging, mobile phone box, wine box, tea box, gift box, luggage, leather goods, computer holster, clothing, whiteboard buckle. Because the single-sided magnet uses a zinc-iron shell to wrap one side of the double-sided magnet, the magnetic side of the wrapped side will be shielded, the magnetic force will be refracted to the other side, and the other side of the magnetic enhancement; To meet the requirements of the gift box ideal magnetic force, but also can save the cost of use. Of course, magnetic stability is very important, with a bad material made of magnets will be a lot of sex, will let the user lose a lot.
