China Neodymium And Ferrite Magnets Manufacturer & Supplier 
N42 magnet is one of the performance grades of rare earth neodymium magnets. It has a high magnetic energy product and magnetic strength, and is mostly used in motors, generators, sensors, magnet components, medical equipment, magnetic clamping and other applications in the industrial field. Today, Neodymium magnet manufacturer Courage Magnet will introduce you the grade and strength of N42 magnet.
What is the meaning of n42 magnet?
N42 is the material grade of neodymium iron boron magnet, N represents the abbreviation of neodymium iron boron, and 42 represents the maximum magnetic energy product of this neodymium iron boron product material, which is 42MGoe, Its size directly indicates the level of magnetism.
Neodymium magnet N42 grade basic parameters (remanence/coercivity/maximum magnetic energy product/maximum operating temperature)
At present, the highest grade of NdFeb in the commercial market is N52 (some manufacturers have the standard N55), and the lowest is N35 (some manufacturers provide N33,N28, we do not provide).
How strong is the N42 magnet (N42 magnet strength)?
N42 grade does not have a fixed tension and Gauss value, the specific magnetic strength depends on the size, shape and geometry of the magnet, if you need to evaluate the tension value of N42 grade neodymium magnet or Gauss value need to provide relevant dimensional data, the following is a list of some tension and Gauss data.
N42 grade 3mm x 2mm neodymium circular thin magnet, with a vertical tensile force of approximately 0.2kg and a surface magnetic strength of approximately 3600 Gauss.
N42 grade 6mm x 1mm neodymium circular small flat magnet, with a vertical tensile force of approximately 0.2kg and a surface magnetic strength of approximately 1820 Gauss.
N42 grade neodymium circular magnet with a diameter of 8mm x 3mm, a vertical tensile force of approximately 1.2kg, and a surface magnetic strength of approximately 3400 Gauss.
The 30x10x2mm N42 grade rectangular Neodymium magnet has a vertical pull of about 1.5kg and a surface magnetic strength of about 1600 Gauss.
N42 grade 10x10x5mm square neodymium magnet, vertical pull about 3.3kg, surface magnetic strength about 3900 gauss.
N42 related grades and N42M, N42H, N42SH, N42UH, their main difference is that the coercive force is different, so the temperature resistance is different, the magnetic strength is not different, such as N42M temperature resistance of 100℃, N42H 120℃, N42SH 150℃, N42UH 180℃.
