Silver jewelry is very popular among young women because of its low price and stylish appearance. However, some netizens said that these dazzling silver jewelry are filled with a large number of fakes to shoddy. With this question, CCTV Finance is true. A field trial was conducted.
At the show, Chen Hao invited an audience to choose the silver-like one among the four bracelets that were prepared. The audience hesitated to pick the silver bracelet that looked like a real silver bracelet. It seems that the imitation silver bracelet can really be fake. Next, Chen Hao touched the silver with a silver content of 99.0% with a small magnet with a diameter of 1 mm. It was found that there was no attraction between the magnet and the bracelet, whether it was the patterned side or the smooth side of the inner ring. Force, can't suck it.
Next, try this silver bracelet with a silver content of 92.5% and the magnet is not attractive. Is it related to the purity of silver? The result shows that there is a silver with a silver content of 92.5% between the bracelet and the small magnet. It is also unattractive, and it seems that there is no attraction between sterling silver and magnets. Next, Chen Hao continued to experiment. When a small magnet touched the imitation silver ring, the small magnet and the ring immediately sucked.
It can be seen through experiments that there is no attraction between silver and small magnets, and there is mutual attraction between silver-like jewellery and magnets. This is because magnets mainly adsorb ferromagnetic substances such as iron and nickel. The main components of imitation silver jewelry are nickel plating of alloy copper and nickel plating of alloy steel, so they can attract each other. But silver is not a ferromagnetic substance, so it can't interact with the magnet. During the experiment, it was also found that when magnet attraction experiments were performed on different imitation silver ornaments, some silver jewelry sucked slowly, while others sucked in an instant. There are two reasons for this. First, The attraction is related to the content of nickel in imitation silver jewellery. Secondly, in the nickel-plated alloy steel, in addition to the presence of nickel, there is iron, so it increases the attractiveness. Through on-site experiments, it is found that magnets can distinguish between true and false silver ornaments, but we still have to remind everyone that the most professional and scientific method is to go to a professional testing institution to use professional instruments to identify whether the silver jewelry you bought is true.
