Why can 999 silver be attracted by magnets?

999 silver is the silver product with the highest purity and generally will not be attracted by magnets. If the magnet can attract silver jewelry, it means that the silver jewelry is not pure silver. It is recommended to go to the local gold and silver testing center for further identification.

999 silver, also known as S999 fine silver, usually refers to jewelry with a silver content of no less than 99.9%. It is a silver product with the highest purity standard stipulated by the state.

999 silver has a white and shiny appearance, is polished, and has a soft texture. When buying 999 silver jewelry, you should check whether the silver jewelry has the silver content mark required by the state, or you can ask the merchant to show the national standard metal jewelry certificate.

What does N stand for and what does S stand for in magnets?

The N of a magnet stands for the North Pole, and the S stands for the South Pole. The direction of the magnetic field lines is from the N pole of the magnet back to the S pole, that is, the magnetic field lines of the N pole are outgoing, and the magnetic field lines of the S pole are incoming. Between magnets, the same poles repel each other, and the opposite poles attract each other.

The method to distinguish the s pole and the n pole is to suspend the midpoint of the magnet with a thin wire. When it is stationary, its two ends will point to the south and north of the earth respectively. The end pointing to the north is called the north pole or the N pole, and the end pointing to the south is called the south pole or the S pole.

The components of magnets are iron, cobalt, nickel and other atoms, which have magnetic moments. Magnets can generate magnetic fields and have the characteristics of attracting ferromagnetic materials such as iron, nickel, cobalt and other metals.

Can a magnet-generated light bulb stay lit forever?

A magnet-generated light bulb cannot stay lit permanently. If the magnet and the copper wire are in a relatively static state, and there is no magnetic line cutting or change in magnetic flux, electricity cannot be generated. If an external force is applied to cause the magnetic flux to change, it is no different from a hand-cranked generator.

Magnets are able to generate magnetic fields and have the property of attracting ferromagnetic materials such as iron, nickel, cobalt and other metals.

Magnets can be divided into "permanent magnets" and "non-permanent magnets". Permanent magnets can be natural products, also known as natural magnets, or they can be artificially made. Non-permanent magnets, such as electromagnets, only become magnetic under certain conditions.

Between magnets, like poles repel each other and opposite poles attract each other.
