We all know that magnets have north and south poles, but it is generally impossible to tell which is the north pole and which is the south pole with the naked eye. Therefore, if magnets are not marked, workers will not know which side is the N pole or S pole when operating them. Why do some magnets need to be marked, while others do not? Below, NST Magnet Manufacturer will explain this to you.
In our daily lives, some gift boxes and injection-molded parts require the use of magnets, and once the magnets are placed inside, they cannot be removed, or the cost of removal is extremely high, which can directly result in product scrap. Why is this such a serious issue? Because they utilize the principle of opposite poles attracting each other to form a mechanism similar to a switch lock. If the poles are the same, it will prevent the mechanism from closing properly, necessitating the removal of one of the magnets and its reinstallation in the opposite direction. This results in additional production steps, potentially damaging the product and causing waste.
Draw a line on the surface of the ring ndfeb magnet to distinguish between the north and south poles.
Ferrite or neodymium arc segment magnets used in motors usually require a specific direction of magnetic field to function properly. If not labeled, this may result in incorrect NS alignment, causing the motor to malfunction and leading to unnecessary trouble and losses.
For some applications that only utilize magnetic attraction and do not rely entirely on magnetic poles, N/S markings are not necessary.
In summary, whether magnets need to be marked with N S depends mainly on the application. Two magnets used in pairs need to be distinguished, while single magnets used for adsorption applications do not need to be marked. As an experienced magnet manufacturer, we will ask our customers about their applications and confirm whether marking is necessary.
