China Neodymium And Ferrite Magnets Manufacturer & Supplier 
Most people think that the greater the gauss of the magnet, the stronger the magnetic force will be. In fact, this is wrong. Today, the Chinese magnet supplier courage magnet Xiaofu will introduce to you the size and pull of 3000 gauss magnet that you may be concerned about.
First question: How big is a 3000 Gauss magnet?
Gauss is a measure of the strength of the magnetic field, not the size or shape of the magnet. It can be large or small. For example, a magnet with a diameter of 2mm and a thickness of 2mm can reach 3000 Gauss, but its size is very small, Looking at a Gaussian value alone cannot determine the size of a magnet.
Measured gauss of 2x2mm neodymium disc magnet is greater than 3000.
Second question: How strong is a 3000 Gauss magnet?
There are also people who ask how much pull force 1000 gauss is. It is the same. First of all, the unit of magnetic force is not GS (Gauss), Gauss is the unit of magnetic field strength, so it cannot be said that how many Gauss is equal to how much magnetic force.
Secondly, the suction force of the magnet is related to the performance of NdFeb and the size of the specification. The higher the performance grade of the magnet of the same specification, the stronger the magnetic force will be.
There is a misunderstanding, that is, many people will think that the larger the size of the magnet table magnetic will be higher, this is not true, the higher the magnetic table indicates the greater the suction unit area! Suction = unit surface magnetic x unit area. Therefore, can not simply think that the table magnetic height of the magnet suction must be large!
For example, N50 grade D3x8mm circular magnet suction < N40 grade D10x3mm circular magnet > N35 grade D10x3mm circular magnet, although the surface magnetic strength of D3x8mm is greater than D10*3mm.
Conclusion:
There is no fixed size for a 3000 Gauss magnet. It can be a 2mm diameter magnets, a 20mm diameter magnet, or a 30mm diameter magnets. There is no fixed pull, it could be 100 grams, it could be tens of kilograms.
