I. Magnetic strength
There is a huge difference between salvage magnets and ordinary magnets in terms of magnetic strength. Salvage magnets are made of stronger magnetic materials and are magnetised to a certain extent, with a magnetic strength of up to thousands of gauss, which can quickly adsorb ferrous objects in the water. While the magnetic strength of ordinary magnets is relatively weak, can only adsorb some smaller or lighter items.
Second, the use of the environment
Salvage magnets are mainly used in the recovery and cleaning of items in the water, such as picking up ferrous rubbish at the bottom of the river, items lost in the water by ships, etc. Therefore, the external surface of salvage magnets is not suitable for the recovery and cleaning of items in the water. Therefore, the external material of salvage magnets usually need to have corrosion resistance, waterproof and other characteristics. On the other hand, ordinary magnets are widely used in industry, scientific research and other fields, for example, used in physics experiments for magnetic field preparation, used in motor manufacturing for motor rotor and so on.
Third, the use of the effect
The effect of salvage magnets in the water is significantly better than ordinary magnets. Due to the high magnetic strength of the salvage magnet, it can quickly adsorb iron objects in the water. While the magnetic strength of ordinary magnets is relatively weak, for some larger, heavier items, you need to adsorb many times, the effect is not good.
In summary, salvage magnets and ordinary magnets in the magnetic strength, the use of the environment and the use of the effect of large differences. Therefore, when choosing magnets, you need to choose according to the application scene and the characteristics of the items, in order to achieve the best use effect.
