Flexible response to different projects, highly customizable magnet solution-Sanen Magnetic Industry
Magnets, as a classic material, have been deeply rooted in people’s hearts and are widely used in various fields. Magnets are often composed of two poles, named "North Pole" and "South Pole", referred to as N and S for short. These two letters are also often used to represent different kinds of magnets, namely "NS" magnets and "SN" magnets. But what is the difference between these two magnets? This is the key point we are going to explain today-the mystery of magnet poles: NS dispute! In this article, we will introduce this puzzling topic from many aspects.
I. Dimensions and specifications
Magnets with different sizes and specifications are necessary to meet the needs of different scenes. Among the two types of "NS" magnets and "SN" magnets, different size specifications will also lead to differences in their applicable scenes, magnetic force and service life. Generally speaking, "NS" magnet has stronger magnetic force than "SN" magnet, but it is slightly inferior to the latter in service life. This is one of the reasons why "NS" magnet may be more stable and reliable in some occasions, while "SN" magnet is needed in other occasions.
Second, the magnetic force is different
Magnetic force is also one of the important properties of magnets. Different kinds of magnets have different magnetic forces. Generally speaking, as mentioned above, the magnetic force of the "NS" magnet is stronger than that of the "SN" magnet, which is why the "NS" magnet is usually chosen when a larger magnetic force is needed. Of course, "SN" magnet also has a place in some occasions where magnetic force is not too high, but it needs to be more durable.
Third, the material and quality
The material and quality of magnet directly affect its magnetic ability, service life and other important indicators. Magnets with different materials and qualities will also have certain differences in performance. In this respect, what we often call "NS" magnets and "SN" magnets are more different in terms of specifications and magnetic force. For the difference between material and quality, the choice of general materials will also depend on the specific situation. For example, in some cases, we will choose to use better quality magnet materials to better adapt to local environmental factors such as temperature and humidity, thus improving the service life and stability of magnets.
Iv. suggestions
In a word, "NS" magnet and "SN" magnet have different advantages and disadvantages in application occasions, magnetic force and service life. Therefore, in the specific use, we need to choose and use different magnet materials reasonably according to our own actual situation. In addition, when selecting magnet suppliers, factors such as material quality, flexibility of specifications and magnetic force should be considered in order to obtain better magnet products and services. Here, we recommend that you try to use the magnet products of "Sanen Magnetic Industry", which provides a variety of size choices, flexibly meets the needs of different projects, and provides you with highly customizable magnet solutions to meet your diverse needs.
I. Dimensions and specifications
The size specification of magnet is one of the foundations of its applicable scene and performance. Among the two categories of "NS" magnets and "SN" magnets, different size specifications will also lead to differences in their applicable scenes, magnetic force and service life.
The usual specification of "NS" magnets is brand 50 or 57, that is to say, the diameter of such magnets is generally within 50mm or 57 mm.. The specification of "SN" magnet is relatively smaller, generally only 15 or 20 brands. This also means that "NS" magnet is undoubtedly a better choice when larger diameter or stronger magnetic force is needed. However, "SN" magnet can also play a good role in some narrow or low magnetic requirements.
Second, the magnetic force is different
Magnetic force is one of the most basic properties of magnets, and it is also one of the core indexes that determine their performance. There are also obvious differences between "NS" magnet and "SN" magnet in magnetic force.
Generally speaking, the magnetic force of "NS" magnet is stronger than that of "SN" magnet. When in use, this means that "NS" magnet can better complete some tasks that require high magnetic force, such as magnetic adsorption and fixation. However, the performance of "SN" magnet is not undesirable in some situations that do not require too much magnetic attraction or require longer-term stability.
Third, the material and quality
The material and quality of magnet directly affect its magnetic ability and service life and other important indicators. For "NS" magnet and "SN" magnet, the difference is that the understanding of the production process is slightly different when the materials are made, which will also lead to some differences in their performance of stability and life.
Magnets with different materials and qualities will also have certain differences in performance. For example, high-quality magnets have strict production requirements and high standardization requirements, and their appearance has obvious defects in all aspects. In contrast, some cheap magnet products may have some obvious shortcomings, such as unstable magnetic force and easy wear. Therefore, when selecting magnet suppliers and manufacturers, we need to seriously consider their materials and quality in order to achieve better use results.
