Giant Magnetoresistance Have you ever sat around on a rainy day contemplating your computer’s hard disk drive? Though often taken for granted, this magnetized device makes it possible to store and retrieve information digitally – in everything from video games to iPods to your personal computer. The first hard disk drives (HDDs) date back to [...]
Permanent Magnets: A Study in Sticktoitiveness There are two basic kinds of magnets permanent and temporary. We'll take on permanent first which is appropriate, because before humans could invent and exploit temporary magnets, they had to discover the permanent kind first. People first happened upon magnets sometime before 600 BC with the discovery of the [...]
Hybrid Magnets: Best of Both Worlds Unlike most of the math that goes on at the Magnet Lab, the equation you need to make a more powerful continuous field magnet is pretty easy. Take a very powerful superconducting magnet say, 11.5 tesla and a very powerful resistive magnet say, 33.5 tesla and put them together. [...]
Electromagnets: Two Forces Team Up Resistive electromagnets, another type of temporary magnet, combine the powers of electricity and of magnetism to enormous effect. Although superconducting electromagnets, which we'll discuss soon, offer many advantages, certain laws of physics prevent them from reaching the field strengths electromagnets are capable of. Some of the world's most powerful resistive [...]
Superconducting Magnets: Power Unplugged Superconductivity is a very cool phenomenon in which electrical resistance is overcome with the help of very cold temperatures colder than anything this side of Pluto! Most superconducting magnets are made using an alloy called niobium-titanium "Ni-Ti" for short. You could think of it this way: In a superconducting current, the [...]
A Boost for Permanent Magnets Scientists at TU Darmstadt explored on an atomic level how changes in iron content influence the micro-structure of samarium-cobalt based permanent magnets. Their results were published in Nature Communications. In the long run they could contribute to the development of permanent magnets with improved magnetic performance. These magnets can be [...]
Scientists Discover Potential Path to Improving Samarium-Cobalt Magnets Scientists have discovered a potential tool to enhance magnetization and magnetic anisotropy, making it possible to improve the performance of samarium-cobalt magnets. The scientists, at the U.S. Department of Energy's Critical Materials Institute at Ames Laboratory, in collaboration with the Nebraska Center for Materials and Nanoscience and [...]
HOW OUR MAGNETIC COUPLING IS MADE Above a typical application History Longer than 40 years went out since we began collaborating with various Italian companies specialized in the design and construction of machines and systems to produce and molding polyurethane components. Many of these companies are now international leaders and are an excellence of the [...]
PERMANENT MAGNETIC COUPLING SOLUTIONS BY HSMAG INNOVATION QUALITY EXPERIENCE A magnetic coupling is a system that transfers torque from one shaft to another using a magnetic field rather than a physical mechanical connection.Magnetic couplings are the most of the times used in pumps and propeller systems. This way a static physical barrier can be placed [...]
A Breakthrough in Magnetic Material Surface Technology A few days ago, the magnetic material surface technical team of the Institute of Rare Earth Materials of Baotou Rare Earth Research Institute used the plasma spraying-grain boundary diffusion method to use heavy rare earth oxides to change the coercivity of the 50M magnet under the condition of [...]
How to Measure the Density of Magnetic Materials? Materials that respond in a certain way to a magnetic field are called magnetic materials. According to the magnetic strength of the material in the external magnetic field, it can be divided into diamagnetic material, paramagnetic material, ferromagnetic material, antiferromagnetic material and ferrimagnetic material. Ferromagnetic substances and [...]
