In consumer electronics, the notable characteristics of magnetic material applications include miniaturization, high efficiency, and reliability. Rare earth magnetic materials such as neodymium-iron-boron (NdFeB) possess extremely high magnetic properties, capable of providing powerful magnetic force within extremely small volumes. This is particularly crucial for modern consumer electronic devices that pursue sleek and lightweight designs. These materials exhibit excellent stability and high-temperature performance, ensuring consistent magnetic behavior across diverse operating environments, which enhances the overall reliability of the devices. The designability and flexibility of magnetic materials also enable them to meet diversified needs. For instance, by adjusting the shape of magnets and the magnetic circuit design, the user experience of products can be optimized, such as improving vibration feedback in smartphones or enhancing the stability of magnetic connections in wireless headphones.
