Once I went to Dalian jewelry store, the boss said that pure silver can be attracted by strong magnetic field. It is also said to be a high-tech magnet in Hong Kong. Really? At that time, I laughed at my boss for not knowing anything. Impossible, it can only attract iron, cobalt and nickel, but not aluminum. You can also use aluminum and compass to check the "magnet", unless the mass of the "magnet" is hundreds of millions of times that of silver according to the law of universal gravitation, but I guess it is really such a thing that the boss can't carry it. When you say boss, I think it's cheating you with cheap metal in the replacement reaction of silver nitrate. Some people upstairs say it's other alloys, but those alloys are too low to attract. You can measure the density. If it's not the density of silver, it means the boss is lying to you.
