The strong magnetic force of this magnet means higher efficiency and longer service life. It can make the motor more delicate and efficient, bringing you a better convenient experience. The advantage of neodymium iron boron magnets lies in their long-lasting durability. Neodymium iron boron magnets used in motors have high coercivity, high magnetic energy product, and good temperature stability. A good motor not only needs to be able to operate stably for a long time, but also needs to be able to maintain stability under various complex conditions.Neodymium iron boron magnets: 26

What coatings do neodymium iron boron magnets have? Due to the presence of iron element in sintered neodymium iron boron magnets, the coating is a very important part of neodymium magnets. Although we can offer multiple electroplating options, nickel is still the most common and usually the preferred.Nickel plated magnets actually consist of three layers of nickel plating, copper plating, and nickel plating. This three-layer electroplating makes our sintered neodymium iron boron magnets more durable than single-layer nickel plated magnets. Other coating options include zinc, tin, and rubber, epoxy resin, silver, and gold.Sintered neodymium iron boron magnets can be used in many products at room temperature and some higher temperatures up to 200 ℃. The application fields include wind energy, petroleum energy, automobiles, electronics industry, IT, healthcare, mining, audiovisual, sports, toys, stationery, printing, packaging, gift handicrafts, etc.Common shapes: discs, rings, cylinders, squares, bars, etc.Irregular shapes: arc-shaped, co: 26

The most powerful magnet in the world, can it absorb iron from the blood We have also seen a lot of iron in our daily lives, and its uses are also very wide. Many things we come into contact with in our daily lives contain iron, and scientists attach great importance to this substance. It is said that there is the strongest magnet in the world, and some people have proposed that it can absorb iron from human blood? Many people also expressed confusion, let's take a look together.The strongest magnet in the world is neodymium magnet. Some people want to give it a try. If this magnet encounters iron in the blood, what will happen? A foreigner bought a neodymium magnet and wants to conduct an experiment. Everyone should be very curious about what will happen. Everyone knows that iron is also a substance in the blood of the human body.After purchasing an angry magnet, the foreigner placed a large kettlebell across the wooden board. When he picked up the kettlebell, the neodymium magnet still tightly adhered to it. We can see how strong the magnetic force of: 25

Magical attraction Now we know why an external magnetic field can generate net magnetism in aluminum. But this is not enough to explain why there is attraction between two substances? To answer this question, we need to use a concept called exchange energy. Exchange energy is a physical quantity in quantum mechanics that describes the strength of the interaction between two adjacent electron spins. Simply put, the exchange energy determines whether the spin of two adjacent electrons tends to be parallel or antiparallel.For the small magnetic dipoles inside aluminum, in the absence of an external magnetic field, exchange energy causes them to tend towards parallel arrangement; When there is an external magnetic field, exchange energy makes them tend to align with the direction of the external magnetic field. This forms a stable state.Between two pieces of material? If both materials are excited by an external magnetic field and have the same direction, there will be an exchange energy between them, causin: 25

The application of neodymium iron boron magnets in loudspeakers But many people don't know that if a magnet loses its magnetism after being used for a long time, what should we do at this time? Below, the editor will introduce to you how to remove magnetism from a magnet!Tool materials.Magnets have strong adsorption power and can hold onto small objects. But over time, a strong magnetic field will be generated. What if we want to eliminate the magnetic field of a magnet?Method steps.Firstly, we need to prepare a dry cloth or tissue to wipe away the dust and other dirt on our palms or soles;2. Then we put our hands on a non charged metal and rub it a few times;3. Next, we will place this charged hand on another uncharged metal and rub it a few times;4. Finally, we can put the charged hand back in its original position;Precautions.1. When erasing, be careful not to touch the skin to avoid the risk of electric shock!2. Before erasing, be sure to keep your hands clean and tidy! Otherwise, it is easy to generate static electricity!!3. When erasing,: 25

Introduction to Common Knowledge of Neodymium Iron Boron Strong Magnets I believe everyone knows that in our daily life, magnets are a very common thing, and neodymium iron boron strong magnets are a commonly used type of magnet. As early as several thousand years ago, the working people of our country made the compass, one of the the Four Great Inventions, according to the characteristics of magnets. Until today, magnets are also a very useful thing. From various special electronic devices to everyday teaching aids and toys, the figure of magnets can often be seen. Therefore, let's take you to a detailed understanding of the common knowledge of neodymium iron boron strong magnets:We know that the main component of magnets is ferric oxide, and neodymium iron boron strong magnets are no exception. However, due to the inherent properties of ferric oxide, its attraction to iron objects is not too strong, and its magnetism will gradually weaken over time. In this case, how can we make a magnet with stronger suction that should not decay? Under such circums: 22

Revealing the Magnetic Source of Magnets The reason why a magnet has magnetic force is because its molecules have microscopic magnetism inside. Specifically, each atom in a magnet contains unpaired electrons, which carry a magnetic moment of their own, equivalent to a tiny magnetic field. Under normal circumstances, the magnetic moments of these electrons are oriented in different directions, so there will be no macroscopic magnetic field effects.However, in some cases, such as under the influence of a magnetic field, the magnetic moments of these electrons will interact with each other, resulting in their magnetic moments facing the same direction. When a magnet is exposed to an external magnetic field, the magnetic moments of these electrons interact with each other, causing the magnetic moments of the electrons in the entire magnet to face uniformly, resulting in a macroscopic magnetic field effect.The microscopic effect of electron magnetic moment in this magnet ultimately leads to the macroscopic magnetism of the magnet.: 22

What is the strongest magnetic magnet? What is sintered neodymium iron boron magnet?Sintered neodymium iron boron magnets are the most commonly used type of permanent magnet material. It is made of alloys of neodymium, iron, and boron, forming a Nd2Fe14B tetragonal crystal structure. Meanwhile, according to its raw material composition, it is a rare earth magnet.How is sintered neodymium iron boron magnet made?Customized sintered neodymium iron boron magnets are a complex process that includes the preparation, melting, grinding, pressing, sintering, machining, electroplating, magnetization, inspection, and packaging of formula powders.Preparing the formula magnetic powder is the most important process. Because technicians can add additional rare earth elements to adjust magnetic properties, such as cobalt (Co) for high temperatures and dysprosium (Dy) for better intrinsic coercivity.Why is sintered neodymium iron boron permanent magnet so sturdy?Melted alloy ingots are made into powder using powder metallurgy technology, wh: 21

How are sintered neodymium iron boron magnets classified? Do you know that sintered neodymium iron boron magnets are evaluated based on the maximum magnetic energy product. Take a look at our neodymium magnet specifications page and you will find a rule that the maximum value of grade N35 (BH) is 33-36MGOe in the middle. Therefore, higher values indicate stronger magnets, ranging from N35 to N55.The letter after the number represents the maximum operating temperature (usually in Celsius), ranging from M (100 ℃), H (120 ℃), SH (150 ℃), UH (180 ℃), EH200 ℃) to AH (220 ℃). If there is no letter like N42 after it, the maximum operating temperature is 80 ℃.What coatings do neodymium iron boron magnets have?Due to the presence of iron element in sintered neodymium iron boron magnets, the coating is a very important part of neodymium magnets.
