Select the [principle] NdFeB magnets are: Under the conditions of the use of space allows, choose as long as possible, as much as possible within the hole as small as possible, and thick NdFeB magnet elements.
NdFeB magnets saturation will occur at DC or low frequency AC case, the permeability decreased, so that the effect of high-frequency noise suppression significantly reduced. Small signal filtering, negligible current, but the power cord or power signal filtering, we must consider the peak current. When choosing for interference suppression NdFeB on a single wire, pay attention to: the general length shorter than a single bead of single beads, porous beads than single-hole beads. Should be used wherever possible smaller diameter, longer length NdFeB, while the inner diameter NdFeB To work closely with the outer diameter of the wire.
New functional materials based on high quality NdFeB magnets magnetic substrates, such as carbon, and inorganic non-magnetic materials have been strengthened, strengthen the magnetic field, both generating magnetic material formed a close bond. Not only magnetic substrate such as tenacity, impact resistance and other characteristics, but also inorganic layer of super magnets acid, non-flammable, easy to clean, durable, wear-resistant, beautiful, no radiation characteristics. Corrugated board with magnets and magnet heat transfer element as the major new functional magnetic steel material, has been widely used in metal toys, handicrafts, industrial facade foundry, aerospace, electronic, sound, leather handbags, gift packaging and other industries and other fields, the future will have better prospects.
