  • 7 Lesser Known Applications of Rare Earth Permanent Magnets 1 comment
    Aug 28, 2009 2:46 AM

    Earlier today, I posted an article over at RareMetalBlog after the question of non-defense applications of rare earth permanent magnets came up. Certainly most of us are aware of the use of such materials in motors and generators, but there are hundred of other applications for such magnets - and not just in the form of simple components. By combining magnets and arranging them in special configurations, we can create all kinds of magnetic field shapes and profiles.

    The applications covered include magnetic couplings, MRI systems, NMR systems for well bore drilling, Halbach & Stelter arrays, biomagnetic separation, magnetron sputtering and electronic article surveillance.


    The article is called "7 Lesser Known Applications of Rare Earth Permanent Magnets" and you can read it here.

    The 4 wrong ways to improve magnetic separation magnetic separation time (and 1 way to do it correctly)


    It is vitally important that life science products be consistent from lot to lot. Two batches of the same product produced in the same way should have little variability. In order to achieve a high level of quality control, one must define a strict standard operating procedure (SOP). In the case of a permanent magnet biomagnetic separation device, conditions are usually very stable and so the main parameter to control is the time the vessel is exposed to the magnetic field during production.
