The Strength of A Magnetic Field Depends On
Almost all the customers pay attention to the strength of magnetic field.
Some magnets are strong enough to lift heavy objects. However, some magnets are weak and can only be barely adsorbed on the refrigerator. What points should we pay attention to when selecting magnets, or what factors are related to the magnetic field strength?
1. Materials
Materials must be the first. At present, there are many kinds of magnets on the market, such as Neodymium iron boron, Samarium Cobalt, Aluminum nickel cobalt, ferrite and rubber magnet, etc. In which, the magnetic field strength of NdFeB is the strongest. However, it should be noted that even for the same materials, such as NdFeB magnet, grade N35 and N52 are quite different.
2. Dimensions
Magnets with different sizes have different magnetic field strength. Generally speaking, the larger the size is, the stronger the magnetic field strength is.
3. Shape
The shape of the magnet is generally made as required. Different shapes produce different magnetic field strengths.
4. External magnetic field
The attraction between magnets is different from that between magnets and iron pieces. The combination of iron pieces and magnets will also affect the magnetic field strength.
Of course, there are many other details. The specific situation varies with different application scenarios. Welcome to consult us freely.
