I. Magnetic properties
The magnetic properties of magnets are the main factors to attract metals, which are usually described by magnetization and coercivity. When choosing a magnet, we must consider the type and shape of the metal to be attracted and the required attractive force. Generally speaking, ferromagnetic metals such as iron, nickel and cobalt can be attracted by magnets. For different kinds of metals or metal alloys, it is necessary to choose magnets with corresponding magnetic properties.
Small-sized magnets usually have higher magnetization and coercivity, while large-sized magnets usually have greater attraction. For example, NdFeB magnets have high magnetic energy product and high coercivity, and are suitable for application scenarios requiring high attraction and small size. However, SmCo magnet has high coercivity and stable temperature characteristics, which is suitable for application in high temperature environment.
The materials and magnetic properties of magnets with different performance brands are quite different, so please choose according to your specific needs.
Second, the magnet size
The size of the magnet directly affects its attraction and usage scene. For scenes that need to attract larger metal parts or the surface of metal parts is uneven, it is necessary to choose larger magnets to obtain greater attraction. For some smaller projects or scenes that need to work in a narrow space, you need to choose magnets with smaller sizes.
At the same time, large-size magnets also need to consider the issues of weight and quality. If the selected magnet is too large, its weight will make it difficult to move or install. In addition, if the quality of the magnet is not good, it is more likely to cause permanent magnetization loss or magnetic force weakening.
Third, durability and high temperature resistance
As a mechanical product, magnet needs to ensure its durability and high temperature resistance. Without good durability, the service life and stability of magnets can not be effectively improved. Without good high temperature resistance, magnets will be damaged or lose their magnetism in high temperature environment, which will affect their normal use.
In order to ensure the durability and high temperature resistance of magnets, it is necessary to choose high-quality magnet materials and precise manufacturing processes. Some materials such as ceramic magnets, neodymium magnet and Co-Fe magnets can withstand higher temperatures, while Fe-Al-Nd magnets have relatively weak high-temperature performance. In addition, attention should be paid to avoid overheating or overload when magnets are used to ensure their normal service life.
The ability of magnets to attract metals is well known, but it is not an easy task to choose the right magnet. When selecting magnets, many factors need to be considered, including magnetic properties, magnet size, durability and high temperature resistance. By choosing a suitable magnet solution, magnets can play the best attraction effect in various projects.
