The current trade dispute between China and the United States will almost certainly influence the rare earth elements (REE) market in the not-so-distant future. First, let’s consider that U.S. President Donald Trump has threatened to raise tariffs on steel and aluminum imports invoking Section 232 of the Trade Expansion Act of 1962, which permits action based […]
A new recycling process developed at the U.S. Department of Energy’s Critical Materials Institute (CMI) turns discarded hard disk drive (HDD) magnets into new magnet material in a few steps, and tackles both the economic and environmental issues typically associated with mining e-waste for valuable materials. Ryan Ott, a scientist at Ames Laboratory and a member […]
It’s been almost exactly one year since the world’s most valuable technology company declared its intention to make future iPhones and MacBooks entirely out of recycled materials. And behold: Just in time for Earth Day 2018, Apple is introducing the latest manufacturing innovation that it believes will help the company automate its way toward that […]
Small NdFeB Magnets in SmartphonesNeodymium (NdFeB) magnets are an invisible part of every smart phone. These tiny magnets are critical to the function of the phone, working quietly behind the scenes inside the phone case. These internal magnets are typically used in the speaker, receiver, vibration mode motor, taptic feedback motor, and camera auto-focus mechanism. […]
Toyota Develops New Magnet for Electric Motors Aiming to Reduce Use of Critical Rare-Earth Element by up to 50%.World’s first neodymium-reduced, heat-resistant magnet developed by Toyota, Key element of the foundation required to popularize electrified vehicles. Toyota City, Japan, Feb 20, 2018 – (JCN Newswire) – Toyota Motor Corporation announces that it has developed the world’s […]
When we apply an outside magnetic field to a magnetic material, we are forcing it -coercing it- to become magnetized. Now that it is magnetized, how much of an applied field is required to demagnetize the material? When we measure the applied field that either magnetizes or demagnetizes the material, we measure the Coercivity of […]
Remanence is the remaining magnetic field found in the material after the applied magnetic field is reduced to zero. Remanence is derived from the same word as “remainder” or “remaining” so we can think of Remanence as the magnetic field that remains in the material after the outside magnetic field has been released.Remanence is also […]
Magnetic Permeability is a value that expresses how a magnetic material responds to an applied magnetic field. If a material’s internal dipoles become easily oriented to an applied magnetic field, that material is regarded as being a high-permeability material. If the material’s internal dipoles do not become easily oriented to an applied magnetic field, it is […]
A BH Curve is a graph of the Hysteresis of a magnetic material. Hysteresis is how the material reacts to external magnetic forces. Magnetic materials always resist the external magnetic force to some extent. That extent tells us a lot about the material’s own magnetic properties.
Neodymium/Praseodymium (PrNd) magnets for electric vehicles (EV’s) will be a big driver for the rare earth elements (REE) market over the coming years as EV and hybrid vehicle production ramp up. This will affect the market for all 15 lanthanide series elements, since all of the rare earth elements are present in varying amounts in […]
