The magnet deviation angle refers to the angular deviation between the geometric axis of the magnet and its magnetization direction. It is crucial to control this deviation, especially in high-performance applications, as larger deviations can affect the efficiency of the magnet in devices like sensors and PVD machines. For sintered NdFeB and SmCo magnets, the goal is typically to keep the deviation angle below 3 degrees for optimal performance.** This precision depends on advanced manufacturing processes and high-quality materials.
