What are grades in Neodymium magnets?
Time:09/10/2012
When you see Neodymium magnets classified as N35, N38, N39, N40, N41, n42,N45, N48, N50. have you ever wondered what it means? The letter N short for the words neodymium. And the number after N represents the grade of the magnet. In general, the higher the grade the stronger the magnet. The highest grade so far in Neodymium magnets is N50. If a magnet is labeled as N42SH, then 42 depicts the strength of the magnet and SH refers to the temperature rating of the magnet. If the numbers are not followed by any letters it means that the magnet is standard temperature Neodymium.
