Most of the magnets we often encounter, such as those on our kitchen refrigerator and office whiteboard, are very easy to operate and use, and usually do not cause us harm. However, there are smaller magnets (mini magnets, mini magnets). Although smaller, they are essential for certain applications. Next, let's talk about the purpose of these small magnets.

1. Artwork

In offices and galleries, the small nickel-plated neodymium magnets will not attract people's attention to paintings or other artworks. They are also strong enough to put any pattern on the wall. They have a special effect on walls coated with magnetic paint. Great.

2. Cabinet

Some companies use small magnets instead of countersinks to keep cabinet doors closed.

3. Storage

Similarly, some companies will use small magnets in jewelry boxes and boxes to keep the lid closed when not in use. Magnets can also be used for binding clips and envelopes.

4. Toys

Magnets themselves are not toys, but sometimes they are used inside toys, such as letting action dolls stand upright to levitate objects. The key to using magnets in toys is to ensure that the toy (hence the magnet) will not be swallowed, and the magnet The strength cannot be strong enough to pinch the skin.

5. Music

If it were not for the small magnets in the pickups, electric guitars would not be able to make a pleasant sound in a noisy crowd.

6. Smart phone

Small magnets are very important to the function of smart phones. They work silently in the phone and are often used in speakers, receivers, and vibration motors.

Due to the wide variety, the usual manufacturing method is to sinter rare earth permanent magnets. For raw materials such as samarium cobalt and neodymium iron boron, sintering is carried out under vacuum or protective atmosphere, post-processing and mechanical processing, and the processing components are pure metals or alloys. In addition, ferrite permanent magnets can also be used as processing materials. Of course, using AlNiCo as a raw material is also a good choice. No matter what kind of raw materials are processed, they need to be better manufactured, so that the quality can be better determined and reliability can be improved. As for how magnets are made, choosing well-known manufacturers to process them will play a better role in quality, and then produce better results in quality. Therefore, scientific choice will be the basis for seeking better quality. When choosing a product, we should evaluate the quality of the product in order to achieve better results in terms of reliability, which is naturally the basis for seeking better services. Of course, in the process of magnet sintering, we can use more advanced technology and suitable raw materials to produce various types of magnets for consumers. Of course, when we make a choice, we still need to make better decisions in order to play a better role in use. After all, a better service organization is more worth choosing, so reliability is more satisfying.

Using more advanced technology to process magnets and finding well-known manufacturers to handle them will play a greater role in quality. Only when we have better quality can we be accepted by more consumers. Of course, this is also the basis for seeking better services. Therefore, we still need to choose better so that we can perform better in quality.

I don't know if you have any experience like this, that is, magnets are the things that I like to play in the classroom when I was young, and because magnets can attract iron products or some metal products, they produce a certain amount of attraction, and they also let us when we were young. These children who don't have too many toys play with relish, but many people don't know how magnets are made? Today I will show you how to make a magnet.

We all know that magnets are divided into permanent magnets and non-permanent magnets. Generally speaking, we often see permanent magnets. Non-permanent refers to some magnet devices that can only be magnetic under certain circumstances. Generally, The electromagnet is the most common.

First of all, the first part of the magnet manufacturing process is casting. First, put copper, sulfur, nickel, iron, aluminum and titanium into an electromagnetic furnace to melt all the metals into liquid, and then pour the liquid into the mold. Create the approximate shape of the magnet, but the magnet at this time does not have any magnetism!

The magnet needs to be magnetic. The second step is to turn on the electricity. Tie the magnet to the copper tube and put it into a larger tube, and then charge it with high voltage. At this time, the electrons in the magnet will flow slowly from the positive electrode to the positive electrode. The negative electrode leads to a certain conversion efficiency of the electrons on both sides. It is precisely because of this that after this step is completed, the magnet has magnetism.

So everyone has read about the manufacturing method of magnets and believes that everyone understands that magnets are not so easy to manufacture. Moreover, magnets are now occupying a major position in more and more industries and infrastructure. Therefore, the relationship The research of natural magnetite is still working hard!
