Circular magnets are used in many fields according to different magnetic effects and different sizes.

Circular magnets have many applications, including toys, smart homes, magnetic induction products, etc.

As we all know, a magnet has two poles, which has nothing to do with the shape of the magnet. No matter what shape the magnet is, it has only two poles.

The reason why this sticker is made into many shapes is related to the actual use of the magnet. In different machines, different shapes of magnets are needed to play different roles.

We can see this kind of small circular magnet in many places in our lives, namely luggage magnets, stationery magnets and tool magnets. When I was young, high-end stationery boxes had such a small magnet that could be used for switches. Now many women's bags still have such a small circular magnet for switches;

There is also a toy of ours - magnetic chess. Different chess pieces are engraved on the small circular magnet, and then it is placed on an iron chessboard. It is a very convenient entertainment device.

Round magnets

In addition to these, you can also:

1. Magnets can be used as compasses

2. Magnets can be used as magnets

3. Electromagnetic relays

4. Generators

5. Electric motors

6. Iron removers made of magnets can remove iron dust that may exist in flour, etc.

7. Magnetized water can prevent boiler scaling

8. Magnetized seeds can increase crops to a certain extent

9. Magnetic therapy

10. Rocks of different geological ages often have different magnetism. Therefore, the magnetism of rocks can be used to assist in judging changes in geological ages and crustal movements.

There was also a magnetized cup in those days. This was based on the fact that appropriate magnetism was good for human health. The bottom of this cup was a round magnet of suitable size, which could adsorb heavy metal impurities in the water to a certain extent, which was good for human health. It is still a very popular health device until now. Larger round magnets are used in salvage, mechanical equipment and other fields.
