What are Non-Magnetic Metals? Metals that exhibit weak magnetic responses are categorized as non-magnetic metals. In addition, these metals exhibit a low relative permeability. The measure of magnetization is termed permeability. It is a property that explains the material's response to the magnetic field. Magnetism is of three types: Ferromagnetic, Paramagnetic, and Diamagnetic. Paramagnetic and [...]
List of Non-magnetic Metals List of Non-magnetic Metals with their Applications Compared to magnetic metals, non-magnetic metals are large in number. Transition metals like copper, silver, and gold, to name a few, are non-magnetic metals. The following tables list a few non-magnetic metals, their properties, and their applications. Non-magnetic Metals Properties Applications Gold Good corrosive [...]
Preparation process of sintered NdFeB magnets (4) - Sintering, heat treatment and machining Sintering and heat treatment The blanks pressed by magnetic field orientation are sintered in a high vacuum or pure inert atmosphere to reach a high density close to 95% of the theoretical density. The magnet holes are in a closed structure, which [...]
NdFeB chemical composition analysis (ICP analysis) The chemical composition analysis of NdFeB materials generally includes: 1-Chemical composition analysis of raw materials, including the chemical composition of rare earth metal raw materials, as well as industrial pure Fe, B-Fe alloys and other metals, such as Ga, Al, Nb, Zr, etc.; 2- The chemical composition of the [...]
A 20-kilometer metal rope was thrown into the ionosphere to harness geomagnetism in space In 1996, the US Space Shuttle Columbia released a tethered satellite in space. A nearly 20-kilometer-long conductive rope was connected between the satellite and the space shuttle. up to 3 amps. Electricity is one of the most important inventions in human [...]
Magnetism can generate electricity! Why don't people use the Earth's own large magnetic field to generate electricity? Magnetism can generate electricity, which is a major law known to all. But why can't people use the earth's own magnetic field to generate electricity? This got people thinking. This requires first understanding electricity and magnetism. Electricity and [...]
Application of High Performance Sintered NdFeB Magnets in Wind Power Generators Abstract: The permanent magnet wind turbine adopts high-performance sintered NdFeB permanent magnets, and the high enough coercive force can prevent the magnets from demagnetization at high temperature. The life of the magnet depends on the substrate material and surface anti-corrosion treatment. The anti-corrosion of [...]
Why don't we use the magnetic field provided by the earth to generate electricity? It sounds like a good idea, but it's not very practical. Before we explain why, let's understand how we generate electricity, in case anyone reading this doesn't already know. Electricity (we say "current") is created when charged particles flow, like water [...]
Scientists design new magnets to provide room for sustained nuclear fusion reactions Scientists are working to realize the potential of nuclear fusion as a nearly inexhaustible source of clean energy, one of the ways that is through new and improved magnets that confine the fields of plasmas so that key reactions can occur . A [...]
Magnets Generate More Electricity in Generators Purdue University researchers have developed a parallel arrangement of inner magnets to reduce size and increase the efficiency of low- to medium-power generators. Source: Purdue University Generators have many uses, from cars to airplanes to microgrids. There is currently a strong desire to reduce size and increase efficiency of [...]
GreenSpur, Niron Develop Rare Earth-Free Power Generation Solution GreenSpur Wind and Niron Magnetics have announced a new rare earth-free power generation solution for the offshore wind market. The findings have been validated by ORE Catapult, the UK's innovation and research center for offshore renewable energy technologies. “Existing turbines use radial flux generators and current designs [...]
Amazing! Ectricity Can Be Generated by Magnets Unexpectedly, a magnet and a gyro can design a chic table lamp. This table lamp called iface is equipped with a copper ring. When the magnetic gyro rotates on the top cover, it will light up the bottom. The LED light, since the iface contains an oily liquid, [...]
