Neodymium magnets are divided into sintered NdFeB magnets and bonded NdFeB magnets. Bonded NdFeB magnets are magnetic and corrosion resistant in all directions; while sintered NdFeB magnets are easy to corrode and require coating on the surface, generally galvanized, nickel, environmental protection zinc, environmental protection nickel, nickel copper nickel, environmental protection nickel, copper nickel, etc. Sintered NdFeB is generally divided into axial magnetization and radial magnetization, which are determined according to the required working surface.

What are the uses of neodymium magnets?

Neodymium magnets are used in many ways. Microphone or speaker manufacturers can use this magnet for their products. Not only that, it is also useful in health devices such as MRI scanners. In addition, jewelry manufacturers can provide their jewelry with neodymium magnets.

Where is the safety of neodymium magnets?

Care should be taken when working with neodymium magnets, as these magnets are extremely magnetic. When neodymium magnets collide with force, they can shatter because they are brittle.

And if such a collision occurs, it can hurt people in the environment. The best way to ensure that the magnets do not clump together is to store them in separate packages. The packaging can be cardboard or plastic.

If you wear braces, make sure you don't have magnets near you. That's common sense because you don't want to lose your teeth. Again, another safety measure for neodymium magnets is to keep them away from children. This is very important because children can swallow them, which can be fatal.

Also, keep neodymium magnets away from pacemakers. The researchers found that these magnets can impair the performance of the device.

Under what circumstances does the demagnetization of neodymium magnets occur?

Before we talk about demagnetization of neodymium magnets, let's talk briefly about what demagnetization means. Demagnetization is a condition in which a magnet loses its power. If demagnetization occurs, you will see that the magnet does not pull the weight it normally pulls.

Many factors lead to demagnetization. Some of them are; Corrosion, excessive vibration, hot and humid environment, etc. Most magnets demagnetize easily. But neodymium magnets are different.

Like most rare earth magnets, neodymium magnets are very resistant to demagnetization. This does not mean that they do not lose strength; It just means a lot of things have to happen. neodymium magnets lose their strength mainly due to overheating.

Standard N-class neodymium magnets begin to lose strength when heated above 80° Celsius. If they are heated above the curio point of 310 degrees Celsius, they completely lose their power.
