Diameter magnetization

The sintered NdFeB magnet is a high properties permanent magnetic material, which is formed by metals Neodymium, iron, boron and some other rare earth elements.

Because of its best properties, reasonable price, the sintered NdFeB magnet are developed rapidly and found in wide applications such as communication, traffic, instrument, electro-acoustics, motors, magnetic therapy, magnetic machinery, magnetic separation, magnetization technology, etc.

Now our company produces high properties magnetic materials in various grades, such as N35-53, 35-50M, 30-48H, 30-42SH, 28-40UH-, 28-35EH with Br 11~14.9 Kgs and iHC 12~30 Koe.

Per your requirement, the sintered NdFeB magnet can be customized into many shapes, such as triangle/square/rectangle/block, trapezium, round/circle/ring/ball(sphere)/sphere/rod/stick/pot, bar, strip, tile/arc, cube, cylinder, cone, disc/disk, segment, etc or some irregular shapes. Our company can also optimize NdFeB magnet with consideration of its work environment(temperature, force, etc).

The NdFeB magnet surface can be treated and coated in many requested ways, such as coated with Zn,Ni,Sn,Ag,Au,epoxy resin or with Pb element eliminated etc.

Q: I know earth has one, and does that mean theres a liquid iron core?: Shop labor is usually around $50-$75 an hour. If you post the symptoms here, I'll bet someone can tell you how to do it yourself.

Q: Classification of magnetic materials: A ferromagnetic material having a ferromagnetic order, and a broad range of weakly magnetic and antiferromagnetic materials that can be applied to its magnetic and magnetic effects. Magnetism is one of the basic properties of matter. Matter can be divided into diamagnetic, paramagnetic, ferromagnetic, antiferromagnetic and ferrimagnetic substances in terms of their internal structure and their properties in an external magnetic field.

Q: Suggest methods to make electromagnet permanent.?: It is not possible to make an electromagnet permanent.Because a ferromagnetic material will behave like a magnet(electromagnet) until a electric field (which is produced by a current carrying coil wound on the material) is provided.It will lose its magnetic property as soon as the field is withdrawn.Although a residual magnetism will remain in the material due to hysteresis loss.This will maintain its magnetic property even after the field is withdrawn or current is made to stop flowing.But the strength will be too weak to consider it as a magnet

Q: Plz tell me in detail that what is magnetic circuit.It‘s uses tell ma the operations construction of any magnetic circuit.: Brake shoes not adjusted? Primary and secondary shoe swapped? All return springs in the right places and secure? Generally, a bad wheel cylinder leaks brake fluid. It's not too common for them to stick.

Q: Could anyone please help me out with these couple of true or false questions? I am pretty sure I know most of them, but they can be confusing. :(1. The magnetic field lines are defined as beginning on N poles and ending on S poles.2. Like poles attract each other and unlike poles repel.3. When a bar magnet is cut in half, one half becomes a N pole and the other half becomes a separate S pole.4. Compass needles are made of paramagnetic material.5. Magnetic field lines always form closed loops.6. Earth North magnetic pole and North geographic pole are different.: 1. True as the North pole represents positive charge and South negative, and since conventional electromagnetism are defined in the way a positive charge would move, field lines begin at North Poles and end at South Poles 2. False As 2 positive or negative charges repel, 2 equal poles would repel each other 3. False, For all practicallity when a magnet is cut in half, the two pieces instantly become identical 2 pole magnets (as in both have a north and south pole), 1 pole magnets are theoretically possible but as of now none have been discovered (this is true spiliting down to protons and electrons) 4. True, as a compass points towards the North Magnetic Pole, it by logic would have to be paramagnetic 5. True, basic definition of magnets 6. True, Earth's North magnetic pole is slightly differnent from the True North or North Geographic Pole (North Geographic pole is defined as place where Earth's axis of rotation meets the surface at 90 degrees North)

Q: After the magnet attracts the mold, how to go to the magnetic?: We use the rice cooker to take advantage of the Curie dot properties of the magnetic material. At the bottom of the rice cooker, a magnet is placed in the center and a magnetic material with a Curie point of 105 degrees. When the pot of water after the dry food, the temperature will rise from 100 degrees. When the temperature reaches about 105 degrees, due to magnetic material of the magnet magnet disappeared, it lost the suction, then the springs between the magnets and magnetic materials to separate them, and drive the power switch is disconnected, stop heating. Curie temperature is the temperature at which material can change between a ferromagnet and a magnet

Q: Induction constant - the energy conversion gained from moving a magnetically charged object on a conductor type material like copper, silver, gold. I guess for every material has to be different. I searched around the net with no luck so I hope someone here might know what I‘m trying to explain.A percent (%) of energy gained or lost in the process. / Difference between the energy needed to run the process of electromagnetic induction and the energy gained from it.: To add to anonymous answer, the eddy currents are a function of the SHAPE of the material as well as the material itself. So in a transformer the core is made of laminations of thin material to minimize those currents. Ferrite uses powdered magnetic material to keep each piece small and reduce the eddy currents that way. So in effect there is no constant that can be applied. The only thing you should be aware of is that the better the conductor the more that energy can be lost in these effects. The second effect is called hysteresis. It takes energy to create a field in a magnetic material. When you reduce that field again you don't get all the energy back. Some has been lost to friction in the material and is turned to heat. Again the losses are dependent on factors such as the frequency of operation. Not a simple constant.

Q: How is the magnetism of a magnet produced?: The principle of magnetic material is divided into many small areas, each tiny area is called a magnetic domain, each magnetic domain has its own magnetic distance (that is, a small magnetic field).

Q: What is magnetic coercivity;give examples of it in at least 1 one experiment?: In materials science, the coercivity, also called the coercive field, of a ferromagnetic material is the intensity of the applied magnetic field required to reduce the magnetization of that material to zero after the magnetization of the sample has been driven to saturation. Coercivity is usually measured in oersted or ampere/meter units and is denoted HC. Coercivity measures the resistance of a ferromagnetic material to becoming demagnetized. Coercivity can be measured using a B-H Analyzer. Materials with high coercivity are called hard ferromagnetic materials, and are used to make permanent magnets. Permanent magnets find application in electric motors, magnetic recording media (e.g. hard drives, floppy disks, or magnetic tape) and magnetic separation. A material with a low coercivity is said to be soft and may be used in microwave devices, magnetic shielding, transformers, or recording heads. As for an experiment, it is used in magnetic information storage. The main challenge in designing magnetic information storage media is to retain the magnetization of the medium despite thermal fluctuations caused by the superparamagnetic limit. If the thermal energy is too high, there may be enough energy to reverse the magnetization in a region of the medium, destroying the data stored there. The energy required to reverse the magnetization of a magnetic region is proportional to the size of the magnetic region and the magnetic coercivity of the material. The larger the magnetic region is and the higher the magnetic coercivity of the material, the more stable the medium is. There is a minimum size for a magnetic region at a given temperature and coercivity. If it is any smaller it is likely to be spontaneously de-magnetized by local thermal fluctuations. Perpendicular recording uses higher coercivity material because the head's write field penetrates the medium more efficiently in the perpendicular geometry. Hope this helps!

Q: What is the material used 2 construct the core of the electromagnet in a telephone receiver?: 1) Lamination of thin sheets of soft iron, with some carbon in it. Steel, in other words. 2) An one of several ceramic magnetic materials. (In historical order)
