N50 grade 3mm magnet is a very small but magnetism strong neodymium iron boron magnet, N50 refers to the grade of the magnet, on behalf of its maximum energy density, the larger the number indicates that the stronger the magnetic force, due to the only 3mm, N50 grade, the information is not detailed enough, the following editorial will be respectively from the diameter of 3mm and the thickness of 3mm, the hole of 3mm to start the introduction.
3mm diameter n50 magnets
With a diameter of 3 mm and a height or thickness that can be greater or less than 3 mm, i.e., round or cylindrical, the dimensions are relatively small and are suitable for use in applications that require a compact design, such as electronic equipment, modeling, and craft production.

3x2mm N50 grade neodymium circular magnet with surface gauss at 3800.
3x1mm neodymium magnet circle

Thickness 3mm n50 Magnets
The shapes are usually round, rectangular, and ring, and although 3mm is not considered thick, for many applications such a thickness is sufficient to provide the required magnetic force, and there is a great deal of freedom in the diameter size, which can be as small as 1mm or as large as 100mm.

3mm thick N50 neodymium magnet surface gauss reference;
8x3mm nickel plated NdFeB round sheet magnets with N50 rating have a surface magnetic strength of 3380 gauss.
3x3x3mm neodymium cube magnet, surface magnetic strength has 4400 gauss.
50x10x3mm motor neodymium block magnet, N50H grade tabulated magnetic strength is around 2100 gauss.
3mm hole n50 neodymium magnets
3mm hole N50 magnets generally refer to N50 grade NdFeB magnets with a 3mm diameter hole in the center, which not only retains the powerful magnetic properties of N50 magnets, but also increases the flexibility of installation and use through the design of the center hole.
