Recently, a group of MIT Plasma Science and Fusion Center (PSFC) research scientists figured out how to manipulate or control the anomalous Hall effect and Berry curvature for advanced use in computers, robotics, and sensors. Hang Chi, Yunbo Ou, Jagadeesh Moodera, and co-authors wrote extensively to explore their discovery and share it with the world.

If you haven’t heard of the James Webb Space Telescope, you are seriously missing out. It is the most powerful space telescope ever built. It lets scientists (and anyone with a phone or computer) see what our universe looked like about a quarter of a billion years ago, 13 billion light-years in the past. Since July 12th, the telescope has been transmitting images of stars, nebulas, planets, galaxies, cosmic dust clouds, you name it! Continue reading →
As concerns and awareness grow regarding the world’s rare-earth element supply, other options are starting to attract interest. One potential alternative involves additive manufacturing or 3D printing magnetic ceramics and alloys that aren’t made with rare earth elements. Continue reading →
Over the past few years, supply chain issues have plagued consumers when it comes to getting everything from groceries to new cars. Now, Europe’s first rare earth magnet manufacturing facility is looking to help with production in hopes of helping people find what they need. Continue reading →
Did you know the modern rare earth permanent magnet was invented at the University of Dayton Research Institute? It all started between 1946 - 1952 when the study of rare earth metals was accelerated by advances in chemical separation techniques (i.e., the Manhattan Project.) Later, in the 1960s, civilian researcher Dr. Karl Strnat and UDRI employee Dr. Alen Ray (serving as a metallurgical consultant) began a study to try and better understand the origin story of magnetic properties.

A magnetic coupling is made up of two integral parts — a driver (connected to the prime motor) and a follower. These pieces could also be referred to as input and output shafts. The former transfers torque to the latter using magnetism vs. a physical connection. This arrangement allows for physical separation between the two shafts. It’s most often used in magnetic drive pumps, liquid pumps, mine motors, conveyor belt motors, propeller systems, and kiln elevators. Continue reading →
Noveon Magnets Inc., a startup in Texas, is on the brink of changing the way we see decarbonization, and they say recycling rare earth magnets is the key. In addition to helping with the country’s efforts to decarbonize, Noveon is focused on the geopolitical and supply chain risks associated with rare earth magnets, hoping to lessen our dependence on China's rare earth metals. Scott Dunn, Noveon’s co-founder and chief executive said, “We don’t want China to just deliver us our quality of living and not have control of our destiny.” Continue reading →
Scientists say there’s a potential new approach to magnet manufacturing that may help Europe and the West lessen (or even eliminate) their reliance on China and its rare earth elements. Ultimately, the desired result of this scientific discovery would be the transition to a net-zero carbon economy. Continue reading →
According to Science Direct, “Magnetic nanoparticles (MNPs) are a class of nanomaterials composed of metals such as cobalt, nickel, and iron, with paramagnetic, ferromagnetic, or superparamagnetic properties.” MNPs are being used in more and more biological and medical applications — “nanomedicine” — from therapeutic treatments and magnetic targeting to cardiovascular imaging, tissue engineering, targeted drug delivery, and disease detection.

One of the first concepts you will learn about in relation to magnets is their poles. We know that lining up the south and north poles will cause your magnets to attract, while lining up two of the same poles will lead to repulsion. The north pole also seeks the North Pole of the Earth when it is free to...
