China Courage Permanent Magnet Manufacturer 
Some customers do not have a clear size of the magnet needs, they only want to request the magnet magnetic strength can reach how many gauss, such as 5000-5999 gauss range, which is more difficult to do, because the single look at the magnet gauss strength is not comprehensive, and may ultimately buy back is not suitable for their own product applications.
A magnet to achieve 5000-5999 gauss, the first need to have a strong magnetic material, this is the most critical, generally only neodymium material to achieve this strength, followed by the need for thicker dimensions, as well as higher magnetic performance levels, such as N50, N52.
The image below shows a measurement of the surface magnetism strength of a round rare-earth neodymium magnet, result is 5830 gauss. The maximum surface magnetic strength is measured near the edge, which is higher than the center measurement.
The following is a compilation of some magnetic strength of 5000 gauss or more neodymium magnets, there are round, cylindrical, ring, the data for manual measurement, there is a certain tolerance, for reference only.
Circular neo magnet size reference for Gauss strength in the range of 5000-5999 gauss;
N52 grade 10x10mm, table magnetic strength is 5570 gauss.
N42 grade D12*10mm, measuring table magnetic result around 5000 gauss.
N35 grade 30mm x 30mm, measuring surface magnetic result of 5280 gauss or so.
N48 grade 50mm x 30mm, surface magnetic field strength of 5910 gauss.
N52 grade D8 * 5.2mm, surface magnetic field strength of 5400 gauss
Size reference for neodymium cylindrical magnets with gauss strength greater than 5000 gauss;
n48 grade D5x16mm neodymium magnet with surface gauss strength up to 5300 gauss
N35 bar neodymium magnets with 10mm diameter and 20mm thickness, surface Gauss strength up to 5170 Gauss
D6*6mm rare earth cylindrical magnets with N40 rating can easily pass 5000 gauss.
Specification reference for neodymium ring rare earth magnets in the 5000-5999 gauss range;
N52 neodymium magnet ring with an outer diameter of 25mm, a hole of 15mm and a height of 13mm has an apparent magnetic strength of around 5460 gauss.
Size reference for neodymium block magnets above 5000 gauss;
N52 grade block magnets with a length of 5.4mm, a width of 3.4mm and a thickness of 6.8mm have an apparent magnetic strength of around 5100 gauss.
10x10x10mm neodymium cube magnets with N52 grade have an apparent magnetic strength of 5220 gauss.
10x10x8mm neodymium square magnets with N52 grade apparent magnetic strength around 5010 gauss.
For 50x50x50mm neodymium cube magnets, the N38 grade can also reach over 5500 gauss.
The above is about 5000-5999 gauss range of rare earth neodymium magnet size recommendation, belongs to the ultra-high strength magnets, generally need to be customized, such as your clear size can be sent to us for your simple evaluation, customization, quotation.
