Neodymium-iron-boron magnets have high coercivity at room temperature, but as the temperature rises above 100C (212F), the coercivity decreases drastically until the Curie temperature (around 320C or 608F). Wenn Sie von diesem verbesserten Service profitieren mchten, melden Sie sich bitte an. This type of corrosion can cause serious deterioration, including crumbling of a magnet into a powder of small magnetic particles, or spalling of a surface layer. Neodymium magnets are brittle so keep them away from hard or sharp surfaces. But Reuters notes that while neodymium costs about $100 per kg and dysprosium costs about $400 per kg, lanthanum and cerium cost about $5 to $7 per kg. The only hitch -it only works on ferromagnetic items. I wrote this article myself, and it expresses my own opinions. Stanford Magnets isone of the leading magnet suppliers across the world whospecializes in manufacturing permanent magnets according to customers requirements in terms of composition, magnetic characteristics, shapes, and sizes. The scientific jury's not out on this one yet, but the number of people who swear by magnetic therapy is staggering. However, many people try to buy and use these magnets for an illegal purpose.
