    Mooring and Maritime Magnets
    Silversea Cruises — a luxury cruise liner with headquarters in Monaco — has begun implementing powerful permanent magnets as a part of their effort to moor passenger excursion boats against the larger vessel. The goal is to deploy Zodiac boats safely, quickly, and efficiently, and return them to the cruise ship in the same manner.  Continue reading →
  2. The Recycling and Disposal of Rare Earth Magnets

    The Recycling and Disposal of Rare Earth Magnets
    While the recycling of rare earth magnets – including neodymium and samarium cobalt – is technically possible, it is not scalable or efficient for most businesses. In fact, less than 1 percent of rare earths were recycled as of 2011, due to a combination of technical, financial, and political reasons. Still, several organizations and scientific studies are attempting to create...
  3. How Scientists Can Use “Greener” Methods to Extract Rare-Earth Metals for Your Smartphone

    How Scientists Can Use “Greener” Methods  to Extract Rare-Earth Metals for Your Smartphone
    Almost all technological products we use daily contain rare-earth metals, from computers and screens to networks, MRIs, batteries, magnets, automobiles, and various types of special optical glasses. They’re also used as a catalyst for oil refining. Because so many rare-earth metals are used in these products, the US Department of Education renamed these commonly found rare-earth metals “technology metals.” A...

    Rare Earth Magnets Recycling Round-Up
    You may have ordered rare earth magnets in the past for a DIY craft, classroom or lab demonstration, or maybe a home organization project, but have you ever looked into where these permanent magnets come from, or how they could potentially be reused? Continue reading →
  5. Recovered Rare Earth Magnets Are Repurposed for Motors

    Recovered Rare Earth Magnets Are Repurposed for Motors
    In a recent blog post, we discussed the importance of recycling rare earth magnets. These rare earth metals play a significant role in everyday technologies, including rechargeable batteries, touchscreen cell phones, and computer hard drives. Through a project funded by the Department of Energy’s (DOE) Critical Materials Institute, a research team in the Oak Ridge National Laboratory (ORNL) recovered magnets from used computer hard drives and repurposed them for use in an axial gap (or axial flux) electric motor, one of two basic direct drive motor configurations. The motor transforms electrical energy into mechanical energy through the electromagnetic interactions of magnetic fields generated by the magnets and coils within. Continue reading →
  6. Exploring the Shelf Life of Your Magnets: Demagnetization, Packaging, and Storage

    Exploring the Shelf Life of Your Magnets: Demagnetization, Packaging, and Storage
    Almost everything has a shelf life. Certainly most food products at the grocery store will “go bad” if you don’t eat them before a certain date, but other products—including electronics, furniture, and even magnets—will weaken, become unsafe, or lose their ability to function as intended if not stored in a standardized setting or used within a certain number of years. If you want to limit damage to your magnets and prolong their shelf life, consider the following factors: net magnetic field strength, proper packaging, and safe storage. Continue reading →
  7. A Rare-Earth Magnet Recycling Process Wins the 2018 Notable Technology Development Award

    A Rare-Earth Magnet Recycling Process Wins the 2018 Notable Technology Development Award
    We all know how important recycling is when it comes to protecting the earth. But did you know that recycling also has an economic component? To put it into perspective, think about rare earth metals. While you may not realize it, rare earth metals are a significant part of the technology we use on a daily basis: touchscreen phones, rechargeable batteries, and even computer hard drives.

  8. Global Industry Analysis of Rare Earth Magnets

    Global Industry Analysis of Rare Earth Magnets
    Rare earth magnets are part of a massive, multi-billion dollar industry that is only growing in size and complexity. A recent study by Grand View Research Firm, Inc. predicts that the already lucrative industry will be worth $38.53 billion by the year 2024; that is a nine percent increase from its $16.5 billion net worth in 2016.  This spike comes...
  9. The Differences in N-Ratings for Neodymium Magnets

    The Differences in N-Ratings for Neodymium Magnets
    Every type of rare earth magnet, whether neodymium, AlNiCo, or something else, has its own alphanumerical system for classifying strength. Each one is unique, and there’s no simple formula for translating a system from one magnet type into the system for another.  Continue reading →
  10. Please Return Your Magnets to their Full, Upright Position

    Please Return Your Magnets to their Full, Upright Position
    Air travel can be a real headache. Before even taking off, there are so many steps to complete and account for. Gathering boarding passes, getting through security, finding the right terminal, and waiting at the gate all add up to a rather hectic and draining experience. On top of all this, Earth’s magnetic field is creating a new problem for runways around the world. Continue reading →
