Neodymium magnet is still the most powerful and frequently used rare earth permanent magnetic material nowadays. Neodymium magnet can be classified to into sintered Neodymium magnet, bonded Neodymium magnet, and hot pressed Neodymium magnet in accordance with the manufacturing process. Each form has their different magnetic properties, then their overlapped [...]

When it comes to the lifespan of permanent magnets, there is no definitive “expiration date” or “shelf life.” Under ideal conditions, a magnet can maintain its ability to generate a magnetic field for years, maybe even decades. However, a variety of factors can gradually degrade a magnet’s performance over time, [...]

Definition of Magnetic Permeability Magnetic permeability is a fundamental property that measures a material’s ability to support the formation of a magnetic field within itself. Scientifically, it is defined as the ratio of the magnetic flux density (B) to the magnetic field intensity (H), expressed as μ = B / [...]

Use in Electric Motors Permanent magnets play a crucial role in electric motors, especially in brushless DC (BLDC) motors, which are widely used today. These magnets create a consistent magnetic field that interacts with the motor’s windings to generate smooth, efficient rotation without the need for brushes. This design reduces [...]
