* Neodymium bar, block and cube magnets are incredibly powerful for their size and grade.And about the grade,it ranges from N35-N52.The higher grade,the higher pull force it is.
* Neodymium magnets are the strongest permanent. Rare-Earth magnets commercially available today with magnetic properties that far exceed other permanent magnet materials.
* Their high magnetic strength, resistance to demagnetization, low cost and versatility
make them the ideal choice for applications ranging from industrial and technical use to personal projects.
