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.

Ferrite & NdFeB Permanent Magnets 20170109

Ferrite & NdFeB Permanent Magnets 20170109
Ferrite Magnets, Sintered Neodymium Magnets, Bonded NdFeB Magnets

Look for Ferrite Magnets  as the Drawings:
I'd like to know if you can supply me ferrite cylinder magnets like below:
Dimension: ***
Magnetized axially
>1500 gauss


Permanent Magnet Manufacturer  China Rare Earth Magnet Limited:
We are an experienced ferrite magnet manufacturer, i.e. ceramic magnets.
As magnets can be specified into different grades, could you please inform us which one you need?
If you could not figure out the grade, please kindly advice attracting force and working temperature.

NB12 & N35H & Y30H-1 & Y30BH Magnets:
According to the engineering department the ferrite magnet we use currently is Y30H-1.
We will order samples of this magnet soon.
We need quote more some kinds of magnets.
Bellow you can find description and quantity to quote:
Bonded NdFeB Magnets NB12
Sintered Neodymium Magnets  N35H
Ferrite Magnets Y30BH

Ferrite Magnets Manufacturer China Rare Earth Magnet Limited:
We'd like to know if there is special surface treatment on ferrite permanent magnets. The surface of the 3 kinds of ferrite magnets is smoother, blacker and brighter than common ferrite magnets.
Please kindly check the quote of Sintered & Bonded NdFeB Magnets first.
Unit price: USD**/pc

Sample Orders:
I would like to ordered these NdFeB magnet samples


The final surface isn't very relevant because the permanent magnet is mounted inside final product. The most important is the magnet force and geometric characteristics.

Permanent Magnets to Quit Smoking 20170105
Neodymium Magnets Manufacturer China Rare Earth Magnet Limited

Look for Magnets to Help Throwing Smoking:
I found information about your company in the Internet and I would be very pleased to receive your answer.
We sell different products through Internet all over Europe countries (and some countries of Asia and South America).
Most of our products are cosmetics and food supplements – products for health and beauty. Now we are searching for the manufacturer of permanent magnets  that can help throw smoking. I would like to check if you can help us with this problem.

Magnet Manufacturer China Rare Earth Magnet Limited:


We customize magnets as per specifications given by customers.
If you would like to have technical information or price of magnets, please provide the following information of magnets you need:
Magnetic Materials: Neodymium Magnets/SmCo/Alnico/Ferrite?
Grade: N35/N38/N40/N42/N45/N48/N52 or ?
Size: ???
Coating: Ni-Cu-Ni/Zn/Black Epoxy or ?
Magnetized Direction: ???
Quantities: ???

Detailed Information of the Auricular Therapy Magnets:
Thank you very much for your answer, but unfortunately I did not know any technical specifications, I know only how they look like and what they have to do. It’s something like this:
Quit smoking with the help of auricular therapy permanent magnets
Natural, no chemicals, no pills
One kit lasts a lifetime
Package contains: 2 biomagnets
Trial order can be discussed, but batch depends on price and production/delivery terms.
Please, let me know if you could provide something like this.

Neodymium Permanent Magnet Manufacturer  China Rare Earth Magnet Limited:
We know it is to put the magnets on an acupuncture point in the ear to stimulate special nerves in the brain, thus to quit smoking gradually. What you need to do is put the smaller magnets inside the ear, and the bigger one outside.
Please kindly check the following price:
Material: N35 Neodymium Magnets
Coating: Gold or Silver
Magnetized Orientation: Through Thickness
