1. The field of electronics and electrical appliances

Speaker/Headphones

✅ is used as a permanent magnet to drive the diaphragm (low cost, corrosion-resistant).

✅ applicable model: anisotropic ferrite (e.g. Y30-Y35).

Electric motors and generators

✅ dc motor tiles (electric car window motors, toy motors).

✅ should select the high coercive force model (such as Y40, anti-demagnetization).

Transformer and Inductor

✅ soft ferrite (Mn-Zn) is used in high-frequency transformers (switching power supplies, anti-EMI devices).

2. Industry and Machinery

Magnetic separation equipment

✅ separation of non-metallic impurities (such as purification of ceramic and glass raw materials).

Door magnetic switch

✅ security system trigger device (strong weather resistance, applicable to -40℃ to 120℃).

Automobile parts

✅ wiper motor, fuel pump motor (low-cost, large-scale application).

3. Daily Life and Others

Magnetic strip for refrigerator door seal

✅ flexible rubber magnet (ferrite powder +PVC).

Teaching AIDS

✅ magnetic plate, compass (safe and non-toxic).

Advertisement display

✅ magnetic whiteboard stickers, display stands (can be cut without damaging the surface).
