Silver jewelry is very popular among young women because of its low market price and fashionable appearance. However, these dazzling silver jewelry are filled with a large number of fakes to make them shoddy. With this doubt, Xiao V will use the characteristics of magnets to make a set Experiment to solve this confusion.

Therefore, there is no attraction between silver jewelry and small magnets, and there is mutual attraction between silver jewelry and magnets. This is because the magnets mainly absorb ferromagnetic materials, such as iron and nickel, while the silver jewelry The main component is nickel-plated alloy copper and nickel-plated alloy steel both have nickel element, so they can attract each other. But silver jewellery is not a ferromagnetic substance, so it cannot attract mutual attraction between it and the magnet.
Magnets can indeed distinguish true and false silver jewellery. Simple testing is a good choice, but we still have to remind everyone that the scientific method is to go to the testing agency and use the instrument to verify whether the silver jewellery you buy is genuine.
