Neodymium Magnet 50mmx25mmx12.5mm

Neodymium magnets are powerful permanent magnets composed of the elements neodymium, boron and iron. These magnets have the highest known energy product for their mass.One of the most appealing characteristics of neodymium magnets is their relatively low cost. Neodymium is the third most abundant rare-earth element, and is far more prevalent than samarium, the prime component of the samarium-cobalt magnets that neodymium magnets have largely replaced.Size-50mmx25mmx12.5mm
