Which is stronger N42 or N52 magnet?
The grades of neodymium magnets that we normally carry are N42, N48 and N52, a rating that is generally measured in Tesla metrics or units of Gauss Oersted (MGOe). A magnet of grade N42 has a Maximum Energy Product of Gauss 42 MGOe, while an N52, at 52 MGOe would be incrementally stronger.
