Does magnet have radiation? Can it be placed at home? The magnetic force of magnets on the market is relatively small and will not generate a large magnetic field, so the magnetic radiation it produces is mostly less powerful, and this radiation is mainly aimed at metallic substances, which is why magnets can firmly attract [...]
New alternatives may ease demand for scarce rare-earth permanent magnets Single crystals of CeCo3 synthesized by solution growth method. From computer hard discs and smart phones to earbuds and electric motors, magnets are at the forefront of today's technology. Magnets containing rare-earth elements are among the most powerful available, allowing many everyday objects to be [...]
Scientists create cheaper magnetic material for cars, wind turbines Scientist Arjun Pathak arc melts material in preparation for producing a new type of magnet. Karl A. Gschneidner and fellow scientists at the U.S. Department of Energy's Ames Laboratory have created a new magnetic alloy that is an alternative to traditional rare-earth permanent magnets. The new [...]
These Powerful Neodymium Cube Magnets are magnetized through their thickness, so the strong North/South poles are located on opposite sides of the cube. After experimenting with them, you will get a feel for which two sides have the strong poles. Neodymium (chemical symbol Nd) is element 60 on the periodic table. It is a rare [...]
Magnetic Alloys Magnetic alloys are alloys engineered to have special magnetic properties. Permalloy Permalloy is the term for a nickel iron magnetic alloy. Generically, it refers to an alloy with about 20% iron and 80% nickel content. Permalloy has a high magnetic permeability, low coercivity, near zero magnetostriction, and significant anisotropic magnetoresistance. The low magnetostriction [...]
The Manufacturing Process of Sintered Neodymium Magnet - How Neodym Magnets are made? Sintered neodymium magnet is manufactured by vacuum powder metallurgy process. The manufacturing process is as follows: 1. Raw Material Neodymium (Nd), Iron (Fe), Boron (B) and other addictives are measured according to the preferred element composition. Raw NdFeB material Raw Material of [...]
