China Neodymium And Ferrite Magnets Manufacturer & Supplier 
3mm diameter round neodymium magnet is a very small rare earth permanent magnet, can be processed according to customer application requirements of different thickness, coating, grade, widely used in a variety of precision electronics, meters, instruments, headphones, handicrafts, toys, etc., today this article will be around its higher than the tensile strength to start the introduction.
3mm diameter rare earth neodymium magnet size reference;
Below is a reference of gauss and pull strength data for common specifications of n35 grade 3mm diameter neodymium magnets;
3x1mm round neodymium magnet with surface magnetic field strength of about 2460 gauss and vertical pull of about 0.1kg, measured 3x1mm can pick up keys weighing 123g.
3x1.5mm small neodymium disk magnets have a surface gauss of about 3050 and a pull force of about 0.15kg.
3x2mm round powerful magnet center surface magnetism strength of about 3420, pull force value in about 0.2kg.
3x3mm small neodymium magnet round, surface magnetism field strength about 3810 gauss, tensile force about 0.22kg.
3mm diameter 5mm height 3x5mm, surface magnetic data about 4090 gauss, pull force about 0.25kg.
3mm diameter 6mm height magnet 3x6mm, surface magnetism data about 4150 gauss, pull force about 0.27kg.
From the above data we can see that for the same diameter, an increase in the height of the magnet leads to an increase in the apparent magnetic data (surface magnetic field strength), this is because the height of the magnet affects its magnetic field distribution and magnetic energy product.
Above is the introduction of gauss and pull strength of some 3mm diameter neodymium magnets, different magnetic performance level, tolerance, magnetization direction and so on will affect the data, just for reference.
