Neodymium magnets, as the 2nd generation of rare earth magnets(the 1 st generation is Samarium Cobalt Magnets) which was discovered independently in 1984 by General Motors and Sumitomo Special Metals. Neodymium magnets well known as NdFeB magnets, made from an alloy of neodymium, iron, and boron. They are the most widely used type of rare-earth magnet and the strongest of permanent magnet available commercially.
Due to their exceptional magnetic properties Neodymium magnets are a key component in various applications.
Neodymium magnets, also known as NdFeB magnets, are composed of an alloy primarily made of three elements: neodymium (Nd), iron (Fe), and boron (B). The combination of these elements creates a powerful permanent magnet with exceptional magnetic properties. The typical composition of neodymium magnets, is approximately as follows:
Neodymium (Nd): About 29-32% by atomic percent.
Iron (Fe): About 63-68% by atomic percent.
Boron (B): About 1-1.5% by atomic percent
Neodymium magnets are classified into different grades, denoted by the letter 'N' followed by a number. Higher numbers indicate stronger magnets. For example, an N52 magnet is stronger than an N35 magnet. Sometimes after the number there will be a letter, like N38EH, EH stands for extra high, means can work under high temperure as 200 degree.
Yes, neodymium magnets typically require plating to protect them from corrosion and improve their overall durability. Neodymium magnets are made of a compound that includes iron, and iron is prone to corrosion when exposed to moisture or harsh environmental conditions. Plating serves several essential purposes for neodymium magnets:
Corrosion Resistance:
The most critical reason for plating neodymium magnets is to provide a protective layer that prevents corrosion. Without plating, the iron content in the neodymium magnet is susceptible to rusting, which can degrade the magnet's performance over time.
Environmental Protection:
Plating acts as a barrier against environmental elements, including moisture and chemicals. This protection is crucial for applications where magnets are exposed to various conditions, such as in automotive, marine, or outdoor settings.
The choice of plating material depends on the specific requirements of the application. Nickel-copper-nickel is a commonly used plating for neodymium magnets due to its excellent corrosion resistance. However, other coatings may be chosen based on factors like cost, aesthetics, or unique environmental considerations.
In summary, while neodymium magnets do not inherently resist corrosion, proper plating is crucial to ensure their long-term performance and functionality in various applications.
Two common methods are used to measure the magnetic strength of magnets: Gauss testing and Pull testing.
Gauss Testing: Gauss measurement gauges a magnet's field strength using a device called a gauss meter.
Pull Testing: This method measures the force required to detach a known ferrous object from the magnet's surface.
The choice between these methods depends on the specific requirements of the application and the accuracy needed. Pull testing is often preferred for its practicality and ease of use, especially in scenarios where reliability and repeatability are crucial, such as in quality control programs.
Rarely, Neodymium magnets are the most permanent magnets in the world. As long as you don't overheat them, they lose less than 1% of their strength every 10 years. With daily use, you basically don’t feel any changes
Yes, Neodymium magnets may demagnetize under the following conditions:
From a medical point of view, neodymium magnets are not harmful to the human body. Moreover, the use of rare earth magnets for magnetic therapy is very common in the medical field. However, if the human body carries medical electronic equipment such as a pacemaker, it is strongly recommended to avoid contact with powerful neodymium magnets, as this may cause serious harm to health. Be aware of potential allergies to the materials used in neodymium magnets, such as nickel. If irritation occurs, discontinue direct skin contact and seek medical advice immediately.
