Tiny, powerful micromagnets consisting of neodymium, iron, and boron are known as neodymium micromagnets. Neodymium micromagnets are widely employed in a variety of industrial, scientific, and consumer applications that demand high strength in a tiny package. Because of their compact size, micro magnets are suited for use in applications where space is limited, such as microelectronics, sensors, and medical equipment. Neodymium micromagnets provided by Tengye are also used in scientific research, specifically in nanotechnology and bioengineering.
