2500 Gauss is a relatively high magnetic field strength that usually requires the use of high performance magnet materials to achieve, here are some things you might want to know about 2500 Gauss magnets.
2500 gauss magnet material selection;
Magnet to reach 2500 gauss, the most commonly used material is neodymium iron boron, which is a kind of rare earth magnet, in addition, samarium cobalt magnet can also meet, but not the optimal choice.
The picture below shows a 2x2mm electroless nickel coated small magnet.
2500 Gauss magnet size；
To obtain a magnetic field strength of 2500 gauss, you need to have some control over the size of the magnet, usually smaller specifications can be higher gauss value, the volume of larger magnets instead of the gauss value is smaller, you can increase the thickness of the magnet or performance level to meet the appropriate.
The following are examples of magnet sizes very close to 2500 gauss and are for reference only, subject to actual conditions.
1, N35 grade 2x2mm small neodymium magnet, surface magnetic strength of 2500 gauss or so, pull strength of about 210g.
2, N35 grade 3x1.5mm small round magnet, surface magnetic strength about 2500 gauss.
3, N52 grade round magnet 4.5mm x 1mm, also about 2500 gauss
4, 9x2mm round rare earth strength, n35 grade at about 2500 gauss.
5, N35 grade 8x5.4x1.8mm rectangular neodymium magnets, gauss also around 2500 gauss
6, N42 grade 41.5mm x 5.5mm x 2.5mm, Gauss around 2500 gauss.
Note: magnet gauss refers to the magnet at a point on the magnetic field strength measurements, such as you need the center position of up to 2500 gauss need to be explained and magnet manufacturers, general magnet manufacturers say gauss value is the maximum surface magnetism, that is, the edge of the position.
Does 2500 gauss require a magnet shape?
No, it can be a block, disk, cylinder, arc, ring or other special customized shapes.
Is a 2500 gauss magnet strong?
A 2500 gauss magnet is much stronger than a regular ferrite magnet, and it will have a greater attraction force and a greater distance of magnetic action, which is enough to meet the needs of many applications that require higher magnetic field strengths, such as in certain industrial magnetic separation equipment, magnetic tools, and even certain medical and laboratory equipment. However, it is not the strongest magnet on the market, as higher field strength magnets exist, such as some high performance NdFeB magnets that can reach 5000 gauss or more.
