N45 Small Neodymium Disc Magnets with 4 Poles with Au Coating

Look for Smallest 4-poles Magnetized N45 Disc Permanent Magnet:

There are three new sizes.
Material: N45 neodymium magnets
Coating: Ag/Ni-Cu-Ni/Au
Magnetized direction: 4-poles NSNS thickness diameter.
Besides, what’s the smallest you could make and still get four symmetrical quadrants with clear and clean inter pole boundaries just as they are now?

Neodymium Magnet Manufacturer  China Rare Earth Magnet Limited:
The smallest possible NSNS magnet size is diameter >4mm, thickness>2mm.
Diameter>4mm and thickness >2mm are both mandatory requirement, i.e. the size shall be D4x2mm.
Please check the following prices:
N45 neodymium disc magnets  with Au coating
Magnetized direction: NSNS through thickness
Unit price: USD**/pc

Ag/Au/Ni-Cu-Ni Coating of NdFeB Permanent Magnets:
I still have the coating of pieces in Ag plating. Seeing I now encase these in plastic, I think Nickel plating might be better.
Nickel plating is stronger isn’t it? Also, if we changed to Nickel plating, will the price reduce by a small amount?
Also, I noticed the Au plating will tarnish much more than.
The reason I don’t have the smallest magnets I order plated in Nickel is because they are not encased in plastic and I need a very inert material coating.
Is there a reason for this and would it help to have them double plated? Say nickel and gold?

Neodymium Permanent Magnets  Manufacturer China Rare Earth Magnet Limited:
Yes, Nickel plating is stronger than Ag plating.
The price of disc magnets with nickel plating is as follows:
Unit price: USD**/pc
Regarding Au plating, actually when you ordered Au plating, we have already double plated the magnets with Nickel + gold.
Just as when you ordered Nickel plating, all we use is Nickel + Cu+ Nickel 3 layers coating.
And please note that in terms of anti-corrosion/oxidation capability, Nickel is much better than Au.
Au coating is just better looking.

Need Nickel + Au Plating Neodymium Magnets:
Please change the magnets to Nickel plating.
The smaller magnets I do not encase in plastic and will need to be finished in Au, but having the double plating with Nickel and Au is what I need.

Latest Study Found that Permanent Magnets can Revive Memories

Generally, when someone told you a phone number, you can dial accordingly. But would you still remember these numbers after ten minutes or even an hour? Although we can’t figure out yet what kind of message our brain will store, a latest research made by University of Wisconsin-Madison might found something special. It pointed out that permanent magnets   may revive memories in the brain.

We always have working memory in our brain, which means that we can keep some important information in the brain for a short moment. And as the previous studies, we only can have these memories through sustained brain activity. However, the new research shows that the brain will conceal the insignificant information out of inspection by monitoring tools.

For the study, a series of experiments were carried out. People were asked to remember two items that represents different types of information like words, pictures, and move directions. At first, the researchers didn’t talk about these words, so the relevant electrical activity and blood flow in the brain disappeared. But then, the activity and flow came back when they were told that some questions about these items will be asked. It is proved that the memory is not gone, we just can’t found it.

And with permanent magnets, these memories can be aroused again. This great discovery may help us to control our minds, thus it may contribute to the treatment of some mental illness, like schizophrenia or depression. Many mental illnesses are relevant with the abnormal thinking ability. For example, the depressed may immerse in a gloomy mood all the time; and the schizoid may have hallucination. And the people with normal thinking ability will ignore these unhealthy signals in our brain automatically. Therefore, the current study may help us to have a better understand on how to control our minds.

A professor of the research team said that we may control our attention, choose what we should think about, and manage some serious problems that caused by a lack of control with the help of permanent magnet   in the future.

Different Coatings of NdFeB Permanent Magnets 20161230

Different Coatings of NdFeB Permanent Magnets 20161230
NdFeB Permanent Magnet with NiCuNi, Zn, Cr, Epoxy, Au, Ag, Parylene

As we all known, although NdFeB magnet is the strongest permanent magnet material so far in the world, it has relatively lower corrosion resistance, therefore, it is necessary to be plated with coatings. Commonly, China Rare Earth Magnet Limited has several different coatings in the market like Ni, Chrome, Gold, Zinc, Epoxy and so on, which will influences the surface color and reserved time separately. Below is the comparison of certain kinds of common coatings.

•     Zn

The surface of Zn coating is always silver and white color. And the NdFeB magnets   with Zn coating is always made by barrel plating with comparatively lower price. It can be kept in salt mist for 12 to 48 hours on average. Besides, it is easy to be attached together with some adhesive such as AB glue.

•     Ni

Usually, the Ni coating in the market means Ni-Cu-Ni three layers, which can stand 120 to 200 hours in salt mist. It looks bright and gleaming. Particularly, it is hard to be oxidized in the air, thus, it is well-like by permanent magnet manufacturers. But the coating is easy to fall off when be used with glues.

•     Chrome 

In the electroplating industry, chrome coating is not familiar for its high costing. But with extremely strong anti-corrosion ability, it is mainly used in environment with high PH value.

•     Gold/Au

The Au coating is always used in jewelry and accessory, which makes it seems beautiful as the real gold.

•     Epoxy

This kind of coating is popular in recent year, namely, it is to add a layer of resin paint after nickel plating. It develops rapidly in various electroplated products nowadays. The greatest advantage of it is this coating can be made to whatever color you want, like black, grey, green and so on.

•     Parylene

The high polymer material has the best protection effect to the NdFeB neodymium permanent magnets whether in the environment of acid, alkali or slat as proved.

In general, it is necessary for the magnets manufacturers to choose the most appropriate coating according different working environment.

How to Choose Right Permanent Magnetic Toys for Your Kids?

How to Choose Right Permanent Magnetic Toys for Your Kids?
Neodymium Permanent Magnets Manufacturer China Rare Earth Magnet Limited

Nowadays, there are various toys that contained permanent magnets  in the market, like magnetic puzzles, magnetic building blocks, magnetic balls, magnetic drawing boards and so on, which is interesting and convenience. Therefore, many parents are willing to buy it for their kids. However, these magnetic toys  may result in serious consequence for carelessness.


Some kids may swallow the tiny parts of magnetic toys or neodymium magnetic balls curiously. Slightly, it will cause abdominal pain, vomiting, fever and other symptoms, and these magnets will expel out of the body automatically later. But in some terrible condition, the magnets in the body will attract the organs like intestines together thus lead to inflammation and necrosis. And it should run operation immediately once the situation occurs.

In May 2015, AQSIQ has released rules and warnings about magnetic toys, and according its introduction, there are mainly two security risks of the toys. For the first is Asphyxia Risk caused by swallow magnetic mini parts or balls accidently. Then is the damage to digestive system. If a kid swallowed two or more powerful neodymium permanent magnets, or other ferromagnetic objects like iron, they will attract together in the digestive system and produce pressure to the intestinal wall, which may trigger off perforation of the stomach or bowel obstruction, or even life-threatening.

Therefore, the parents should pay great attention when choose the magnetic toys. On the one hand, the product specification and identification should be checked carefully to see whether the toy is safe for children and whether the material is environmental-friendly. On the other hand, the parents should choose proper products according the age of their child. In addition, the most important is it would be better for the parents to give appropriate accompany and remind when the kids play these toys.

In a word, with careful treatment, the permanent magnetic toys are beneficial and favorable to the kids.
