The success wining … Magnet Manufacturer China Rare Earth Magnet Limited With its high efficiency, energy saving, reliability and other comprehensive advantages, permanent magnets of China Rare Earth Magnet Limited won a purchase contract of PM synchronous traction motor system, which includes 80kW permanent magnet synchronous traction motor and the auxiliary inverter. The success of wining the purchase contract marks a great breakthrough of CREM in Vessel electric propulsion. CREM started a brand new journey of its magnet traction technology in electric motor vessel, right after the accomplishments of its motor magnets in railway transportation and high-efficiency motors. It is understood that previously the traditional internal combustion engine driven is mostly applied in the field of vessel propulsion, which leads to alarming pollution of air and water. With the increasingly strict national regulations of air and water pollution control, marine shipment and vessels are in urgent need of transformation into electric drive system, so called oil to electricity. Compared to internal combustion engines, electric ships not only have lower operating costs, but also can meet the updated stringent pollution control regulations of inland waterways, lakes, and the harbors. According to the client, compared to the traditional diesel driven ships, in the condition that a ship drives more than 100 kilometers per day, with the traction motors with permanent magnets manufactured by China Rare Earth Magnet Limited, the cost of an oil-electricity driven ship can be reduced by more than 10%, and emissions of pollutants will substantially decrease, which can be widely used in the field of inland river shipping, scenic spot, port and ferry, and will bring us great economic and social benefits. At present, many traditional shipyards has been developing the electric driven vessels, while many inland electric vehicles manufacturers begun to enter the field of electric ships. According to the “2015-2024 market report of midget submarine and the automatic underwater ships” released by foreign market research firm Research and Markets, the market of global electric ships is facing rapid growth with its new performance, affordable costs and legal prohibitions. The report pointed out that the electric ship market, including water and underwater, will see a vigorous growth from $2.6 billion in 2013 to $7.6 billion in 2024. With the growing feasibility of high power electric vessels, electric outboard engine market capacity will increase to 3 times. View Details

Secret: human body can suspend in the air

All substances are certain extent … If the creature is in a strong neodymium magnetic field, will it be suspended like a drop of water? There is a particularly interesting feature about magnetism that when an object is moving in the magnetic field, it creates a force opposite to the direction of movement, which resists the movement of the object. All substances are to certain extent diamagnetic, which means that they are resistant to be magnetized. But for some substance such as permanent magnet , the paramagnetism or ferromagnetam is so strong that the diamagnetism is overwhelmed, thus magnetism is shown. In addition, due to the different degree of diamagnetism, the force repulsion varies greatly. So, where is the interesting part about such characteristic of magnetism? Have a look at the following eye-opening gif. This interesting phenomenon is also referred to as "feather fall". A neodymium magnet and a copper tube are used here. The neodymium rare earth magnet creates a magnetic field, while the copper is excellently diamagnetic. The motion of magnetic field interacts with the copper tube, and induction current is generated in the copper which then creates upward repulsive force that keeps the magnet from falling down, thus give us the image of the object falling down slowly in the air! When the magnetic field is very strong, reaching 20 Tesla, about the strength of several hundreds of ordinary magnets, even the water drops can be suspended in the magnetic field. A drop of water lost gravity and suspended in a magnetic field. Suspended in mid-air, it is there, not sad not happy, never abandon. Why is water suspended in a magnetic field? In fact, water molecules are diamagnetic too. But the molecules are so tiny that the repulsive force it generates is negligible compared to the gravity. But if the magnetic field were strong enough, it could enable the water drop to overcome the gravity and suspend. The vast majority of living organisms are water, and the protein, and so on, are also diamagnetic. Here comes the question: if the creature is in a strong permanent magnetic field, will it be suspended like a drop of water? So, the scientists have also thrown living creatures into the powerful magnetic field. Among them, the funniest one is a frog. When the frog was placed in a magnetic field, every atom of frog likes a small needle. Upward force is created in these small magnetic needles by the external magnetic field. If the strength of the magnetic field is proper, and gravity of the frog is balanced, they can suspend in the air. This frog is probably the first living creature that has been suspended from the earth without the external force such as the flow of air. Well, when it comes to this, it's natural to think if the human body can also be suspended in a magnetic field? In theory, there is no problem at all. According to the principle of diamagnetism, with sufficiently strong magnetic field with neodymium permanent magnets and careful design, human body can suspend in a magnetic field. View Details

There is a huge market products we will from these magnets. Shape: Ingredients of sintered material: Strontium 15%, Ceramic 65%, … Custom Y30 & Y10T Magnets in Ring & Other Shapes Inquire Ferrite Magnets : Can you make the following magnets for me? I want them fully magnetized through the face. There is a huge market for the products we will make from these magnets. Shape: Ring Ingredients of sintered material: Strontium Ferrite 15%, Ceramic 65%, Powdered Bronze 20% (They are intended to be weak magnets. ) The ceramic can be any material that will mix thoroughly and sinter well. Ferrite is a possible choice, though non-magnetic ceramics will do just as well. The powdered bronze is a specific alloy which I will provide to you. Permanent Magnet Manufacturer China Rare Earth Magnet Limited: For the above-mentioned ferrite ring magnets, please could you advise the material grade directly? We can not judge the grade from the composition of material. Sintered Ferrite Magnets: I have in mind that you will mix all three powders together, then create the magnets by sintering this mixture. One challenge is that the bronze melts at 1080C. This means we will want to sinter at a temperature not to exceed 1040C. Can you select materials which will allow sintering at this lowered temperature? For the magnetic material, strontium ferrite grade 23 will work well. Other grades can be used as well, particularly grades that sinter at lowered temperatures. For the ceramic, you can use ferrite, iron oxide (Fe2O3), or perhaps Ni-Zn-Cu ferrite. Please choose whatever ceramic material will sinter at lowered temperature. As I said before, I will supply the powdered bronze which melts at 1080C. Y23 or Y25 Magnets: I am afraid the material Y23 or Y25 is seldom in current permanent magnetic material markets. I will revert back after checking with our related department. Maybe we can quote based on other grade. Magnet Grade: The grade is unimportant to me. Please something which will sinter at lower temperature. Ferrite Magnet Manufacturer China Rare Earth Magnet Limited: The magnets need to be produced by making new molding. The molding cost is US$***. Please find the unit price of magnets as attachment. Y30 Magnets: Does your price include using a mixture of Y30, ceramic, and powdered bronze? (with me providing the bronze.) Also, what will the magnets cost with a gold coating? Approximately how much will the 20,000 units weigh? Y30 Ferrite Magnets: Our price was for standard Y30 magnets. The main material composition is Fe2O3, SrO, CaO, Al2O3.2H2O. Ferrite magnets don't need to be coated with plating. The estimated gross weight of 20,000 units is about 8KGS. The express cost to USA is US$***. Please revert back if you plan to order the magnets. Ceramic Permanent Magnet: Can you make a very weak ceramic magnet for me? I propose mixing the strontium ferrite magnet material with ferrite. (20% Y30 + 80% ferrite.) What is a practical way for you to make a very weak magnet for me? Y30 Magnet Manufacturer China Rare Earth Magnet Limited: Y30 is anisotropic ferrite magnet. You can consider choosing isotropic ferrite like Y10T if you prefer a weaker one. Isotropic magnet is somewhat weaker than anisotropic one. View Details

Recently, doctors put magnets in a patient's body and heal patients with stenosis of bile duct. Yesterday, the first affiliated hospital of Xi’an Jiao tong University announced that domestic first "Stenosis of bile duct repatency operation by magnetic pressure” achieved success. The patient Mr. Wen was conducted abdominal surgery operations three times because of Liver Transplant. Recently biliary stricture complications appeared, the fourth abdominal surgery operation is needed if by traditional treatment method. The Professor Yi LV and other experts of affiliated hospital of Shanghai Jiaotong University thought of Magnetic press fit technique, which uses the attraction between 2 rare earth magnet rings to press scar tissue and to break through the bile duct. The magnet rings are neodymium ring magnets material which is the third generation of rare earth permanent magnet materials. By discussion, and guided by the experts of Northwest nonferrous metals research hospital, the surgery began in the afternoon of December 24, 2011, the doctor passed a guide wire from skin into duodenal, and then lead to mouth by duodenoscope, then two special customized magnetic ring is diameter 4 mm, and thickness 5 mm followed by the Guide wire and successfully placed in the 2 sides of the narrow biliary tract. Because it is the first time of adopting this technology and the lack of experience, the difficulties in surgical procedure were very hard, such as mighty sphincter strength, tortuosity and soft guide wire and the changes in blood pressure by stimulation of the biliary tract. For doctors, all is brand new difficulties. Because of X-light conditions in the operating room, the doctors wore heavy lead clothes to prevent radiation. It took 4 hours from 1 to 5 pm, and then two neodymium permanent magnet rings were finally put into the right place. The patient smoothly passed through 48 hours dangerous period after the operation. A week later, radiography found the 2 attracted magnet rings smoothly get through the biliary tract including the original narrow segments, indicating that the irregular narrowing of the biliary tract has been successfully dredged. 段When the attracted ring magnets were taken out successfully, a new technology is widely used in clinical medicine achieved Zero breakthroughs in the Country. Yesterday morning, the patient Mr. Wen was ready to go home gladly. It is understood that the successful application of this technology, not only for the patients after transplantation with biliary strictures, but also provide a safe, minimally invasive, rapid recovery therapy means for common patients with benign stenosis of biliary tract, can also be used for intestinal anastomose, vascular anatomize and other fields.
