The 180mm large neodymium ring magnet has very strong magnetism, made of rare earth neodymium magnetic material. It has excellent magnetic force and long-lasting magnetic properties, which can meet your needs for strong magnetic fields. Whether you need heavy-duty assembly, motor manufacturing, magnetic levitation technology in the industrial field, or seek innovative solutions in scientific experiments, medical equipment, green energy, and other fields, 180mm (7 inches) large neodymium ring magnets can provide you with excellent performance.
Note:; Large ring neodymium magnets can be punched (countersunk or through-hole). Due to their strong magnetism, please ensure that a safe distance is maintained during use to avoid injury or interference with surrounding personnel, equipment, or magnetic sensitive objects.
