Shuttering magnet with handle

Will the adsorption force of the shuttering magnet with handle become weaker as the number of uses increases?
As the number of uses increases, the adsorption force of the shuttering magnet with handle may gradually weaken, but this change is not absolute, and the degree and speed of its weakening will be influenced by various factors.
Firstly, the material of the magnet is a key factor in determining its adsorption durability. High quality magnets, such as neodymium iron boron magnets, typically have higher magnetic energy product and coercivity, thus maintaining a relatively stable magnetic force after multiple uses. However, even high-quality magnets may experience a decrease in their adsorption capacity over a long period of use due to changes in their internal magnetic domain structure or external factors.
Secondly, the usage environment also has a significant impact on the adsorption force of magnets. Extreme temperatures, humidity, corrosive gases, and other environments can accelerate the attenuation of magnetic force. If magnets are frequently used in these harsh environments, their adsorption force may weaken faster.
In addition, proper use and maintenance are also important factors in maintaining the magnetic attraction. Avoid strong impacts or vibrations on the magnet, as this may cause damage to the internal magnetic domain structure of the magnet, thereby affecting the adsorption force. Regularly cleaning the magnet to prevent the accumulation of dust and dirt can also help maintain its magnetic strength.
However, it should be noted that the weakening of adsorption force is a relatively slow process, and not all magnets will significantly weaken their adsorption force with increasing usage. If the material of the magnet is good, the usage environment is suitable, and it is used and maintained correctly, then its adsorption force may remain relatively stable.
In summary, as the number of uses increases, the adsorption force of shuttering magnets with handles may gradually weaken, but this change is influenced by various factors, including the material of the magnet, the usage environment, and whether it is used and maintained correctly. To maintain the stable adsorption force of the magnet, it is recommended to choose high-quality magnet products and pay attention to their usage environment and maintenance methods.

Can I use a heavy object to directly hit the shuttering magnet with handle when removing it?
When disassembling the shuttering magnet with a handle, it is absolutely not allowed to use a heavy object to directly strike it. Using heavy objects to directly strike not only damages the magnet itself, but may also pose a safety hazard to surrounding people and objects.
Firstly, the magnetism of a magnet is very strong. If it is directly struck by a heavy object, it may cause damage to its internal structure, thereby reducing its magnetism and adsorption force. This will cause the magnet to lose its original function and cannot be used again.
Secondly, the magnet and handle are usually fixed together through a precise connection structure. If a heavy object is used to directly strike, it may damage these connection structures, making it difficult to disassemble the magnet or damaging the handle. This will increase the difficulty of disassembly and may even render the entire shuttering unusable.
In addition, using heavy objects to directly strike may also cause the magnet to suddenly pop out or fall off, posing a safety hazard to surrounding people or objects. Especially if the magnet is attached to sensitive equipment or items, sudden detachment may cause serious consequences.
Therefore, when dismantling shuttering magnets with handles, the correct tools and methods should be used to avoid direct impact from heavy objects. If disassembly is required, tools such as screwdrivers and wrenches can be used to loosen the connection structure, or follow the disassembly instructions provided by the manufacturer. This can ensure the safety of the magnet and handle, avoiding unnecessary losses.
