Used extensively as a permanent magnet material in small electric motors, such as those found in automotive components (e.g., windshield wiper motors, power windows, and fans), due to its good magnetic properties and high resistance to demagnetization. Commonly used in speakers and microphones for consumer electronics and audio devices, providing efficient sound production with lightweight design. Employed in magnetic separators for removing ferrous contaminants from materials in food processing, pharmaceuticals, and plastics industries. Found in refrigerator door seals to maintain tight closure through magnetic attraction. Utilized in educational kits and toys involving magnets because of its low cost and safety compared to rare-earth magnets. Also applied in magnetic recording media and certain types of sensors where moderate magnetic strength is sufficient.
