The composition of NdFeB Magnet is an alloy of bismuth, iron, and boron. NdFeB Magnet is magnetic because the molecular alignment of these alloys tends to be uniform under the guidance of external forces (such as magnetic fields), and thus magnetic properties are exhibited. Unlike other magnetic materials, NdFeB Magnet is a permanent magnet and is relatively magnetic, so it is called a generation of the magnetic king.
NdFeB Magnet magnetic material is the latest result of the development of rare earth permanent magnet materials, because NdFeB Magnet contains an alloy such as iron oxide, which is also called magnetic steel. NdFeB Magnet is widely used because NdFeB Magnet has advantages that other magnetic materials do not have;
1. Extremely high magnetic energy product and force. The magnetic force of NdFeB Magnet is more than ten times that of ferrite. Medical devices made with NdFeB Magnet, such as low back pain treatment belts, analgesic sleeping pads, etc., can maintain long-lasting magnetic properties.
2. High energy density. The high energy density makes NdFeB Magnet excellent in ductility and mechanical properties, and can be manufactured to be compact, lightweight, and thin. This is different from other permanent magnets, making it possible to use permanent magnets extensively. Nowadays, NdFeB Magnet permanent magnet materials have been widely used in modern industrial and electronic technology, from instrumentation, electroacoustic motors, magnetic separation magnetization and other equipment to people's low back pain treatment belt for treating back pain, magnetic therapy knee pads for treating leg pain, There is credit for NdFeB Magnet.
