Nowadays, most of the headphones used by everyone are moving coil or moving iron, and a small number of coil irons are headphones. What is the difference between them? What's the downside? Let's find out together.

According to foreign media reports, Japan will double the subsidies for electric car purchases to up to 800,000 yen ($7,000), almost the same as those in the United States and Europe and provide subsidies for charging infrastructure.

In March 2022, my country's automobile production and sales fell by 9.1% and 11.7% year-on-year, respectively. The sales of new energy vehicles continued to maintain rapid growth, with a market penetration rate of 21.7%.

In the first quarter of 2022, the production, and sales of automobiles in my country have been steadily improving, with year-on-year growth of 2.0% and 0.2% respectively. The production and sales of new energy vehicles both increased by 1.4 times year-on-year.

In the sampling inspection, the OC curve can be used to evaluate the discriminative ability of the sampling plan, but how a sampling plan affects the interests of the producers and users can be specifically analyzed through two types of risks.

Magnetic fluid thruster (Magnetohydrodynamic Drive, MHD) is a channel through seawater built with a magnetic field, this magnetic field can generate electromagnetic force on the conductive seawater, so that it moves in the channel, if the movement direction points to the stern, the reaction force will push the ship forward.

NdFeB magnetic material is made by mixing, pressing and sintering the sieved neodymium, iron and boron ultrafine powder. According to the requirements of product use, it can be machined into different shapes. Because the chemical properties of this material are relatively active and easily oxidized, the finished product needs to be processed by electroplating.

On the morning of August 9, led by Jiangxi University of Science and Technology and jointly completed with Xingguo County People's Government, China Railway Sixth Institute, China Railway Industry, National Rare Earth Functional Materials Innovation Center and other units, the permanent magnet maglev rail transit project test line - "Red Track" It was successfully completed in Xingguo County, Ganzhou, Jiangxi Province.

NdFeB hydrolysis (HD) method is to refine the particle size by hydrogen absorption lattice expansion and dehydrogenation reduction, and hydrogen absorption or dehydrogenation is a reversible chemical reaction process, and the physical and chemical reactions have changes in its chemical composition and magnetic properties.

Pure metal non-contact direct infiltration method for heavy rare earth NdFeB magnets
In fact, using the principle of vapor pressure and vacuum evaporation technology, pure metal is directly infiltrated into rare earth NdFeB magnets.

How to judge the loss of magnetism of the permanent magnet motor rare earth magnet of the permanent magnet DC brushless motor?

The full English name of EPS is Electronic Power Steering, that is, electronic power steering system, which uses the power generated by the electric motor to assist the driver in power steering. As an important part of the whole vehicle, the steering system is one of the key systems that affect the handling stability, comfort and driving safety of the vehicle.

Do you know what are several common coatings for NdFeB, what are the differences between these coatings, and what role do they play?

I thought I wouldn't need to study physics after graduation, but now I don't know magnetism and can't do skin care.

There are not only "Phantom of the Palace Lady" but also "Scientific Shadow" on the red wall of the Forbidden City

High-speed permanent magnet motors offer advantages such as high-power density and efficiency. However, when using non-laminated steel for the rotor, there can be severe losses that may lead to irreversible demagnetization of the permanent magnets. Research has shown that replacing the high-conductivity non-laminated steel sleeve with low-conductivity carbon fiber composite materials can effectively reduce rotor losses.

In fact, Mazda was not the first to make a rotary engine. Everyone knows that the rotary engine is also called the Wankel engine. This person is Felix Wankel, the founder of the rotary engine.

Magnetic coupling is a type of device that transmits torque through magnetism.

Do wind turbines have blades? No! My world view has been refreshed…

Magnetic drive pumps, also known as mag-drive pumps, are centrifugal pumps that utilize a magnetic drive (magnetic coupling) to achieve contactless torque transmission. This eliminates the need for dynamic seals, replacing them with static seals, making magnetic pumps completely leak-free. Their leak-proof design, coupled with their versatility, makes them well-suited for a wide range of applications, including chemical processing, food processing, and pharmaceutical manufacturing.

Casting stress in AlNiCo magnet production can be divided into thermal stress and shrinkage stress. To minimize stress, simplify designs, ensure symmetry and uniform wall thickness. Employ simultaneous solidification techniques for equilibrium and prevention of thermal stress. Aging treatments like natural and thermal aging help eliminate stress. By combining these measures, high-quality AlNiCo magnets with minimal casting stress and superior performance can be achieved.

Silicon steel is the core material of motors and transformers. It can be said as the most core material driving modern industry and is irreplaceable. Due to extremely high technical threshold, it has been monopolized by the world's industrial powers for a long time. China has been developing silicon steel for nearly 40 years, of which the first 20 years were mainly in the digestion and absorption stage. Last 10 years, it has achieved independent research and development and industrialization.

Magnetic materials are basic materials close to the production and development of the national economy. They are widely used in the fields of electronics, information technology, energy and transportation, mechanical engineering, national defense and military industry, etc. According to different magnetic properties, magnetic materials can be mainly divided into permanent, soft and other functional magnetic materials such as moment magnetism, gyromagnetism, and pressure magnetism.
