Overview of the operating properties of NIB magnets.
Neodymium magnets (also known as rare earth, Neo, NIB or NdFeB magnets) were invented in 1982 and are the strongest type of magnets.
There are two basic ways that NIB magnets are made: sintered and bonded.
Sintered NIB Magnets
Sintered NIB magnets have the highest strength but are limited to relatively simple geometries and can be brittle.
They are made by pressure forming the raw materials into blocks, which then go through a complex heating process.
The block is then cut to shape and coated to prevent corrosion.
Sintered magnets are typically anisotropic, which means they have a preference for the direction of their magnetic field.
Magnetizing a magnet against the “grain” will reduce the strength of the magnet by up to 50%.
Commercially available magnets are always magnetized in the preferred direction of magnetization.
Bonded NIB Magnets
Bonded NIB magnets are typically about half as strong as sintered magnets but are less expensive and can be made into almost any size and shape.
Raw materials are mixed with epoxy as a binder, pressed into a die cavity and heat cured.
Bonded magnets are isotropic, which means they don’t have a “grain” or a natural preference for the direction of their magnetic field.
NIB magnets really are permanent magnets, as they lose their magnetism, or degauss naturally, at approximately 1% per century.
They generally operate within the temperature range of -215°F to 176°F (-138°C to 80°C).
For applications that require a broader temperature range, Samarium Cobalt (SmCo) magnets are used.
Because uncoated sintered NIB will corrode and crumble with exposure to the atmosphere, they are sold with a protective coating.
The most common coating is made of nickel, though other commercially available coatings provide resistance to high temperature, high humidity, salt spray, solvents and gases.
NIB magnets come in different grades, which correspond to the strength of their magnetic fields, ranging from N35 (weakest and least expensive) to N52 (strongest, most expensive and more brittle).
An N52 magnet is approximately 50% stronger than an N35 magnet (52/35 = 1.49).
In the US, it is typical to find consumer grade magnets in the N40 to N42 range.
In volume production, N35 is often used if size and weight are not a major consideration as it is less expensive.
If size and weight are critical factors, higher grades are typically used.
There is a premium on the price of the highest grade magnets so it is more common to see N48 and N50 magnets used in production versus N52.
Buy-neodymium-magnets, Neodymium super magnets: Strongest in the world
Many of you might ask yourself: Why is a neodymium magnet a super magnet? And: Wouldn’t a cheaper ferrite magnet be sufficient for my project? The special NdFeB combination (neodymium-iron-boron) results in a high adhesive force even in small magnets.
Hence, ferrite magnets of the same dimensions are much weaker.
We recommend buying super magnets if you need a small, lightweight magnet or a large, extra-strong magnet.
In the assortment of our online shop, you can find the perfect magnet for your project, from mini magnets to ultra-strong neodymium magnets.
Neodymium magnets are slightly more expensive than ordinary ferrite magnets because neodymium is a rare earth metal.
That is why super magnets are also known as rare earth magnets.
We recommend ferrite magnets when:
exposed to temperatures over 80 °C
For outdoor use we also carry some rubberised super magnets .
Also in our web shop: Self-adhesive neodymium magnets e. g.
as clasps for paper and cardboard articles, for name tags and arts & crafts.
A few "strong" facts about our super magnets:
The strongest ring magnet : Ideal for "fishing" for ferromagnetic objects.
It will easily pull your bike out of the river, for example.
Our so-called " death magnet ": A compact block magnet with an adhesive force of 100 kg.
The "strongest" block magnet in our online shop: The block magnet MONOLITH with an adhesive force of approx.
Before using any of our super magnets, please read the safety tips to avoid hazards and injuries.
Our practical adhesive force tool is free of charge and allows you to calculate the adhesive force for a variety of neodymium magnets.
Also, make sure to check our FAQ page , where we put together facts and figures about neodymium magnets for your information.
There you can find out, for example, what the specifications N42, N45 or N52 mean or learn more about the recommended safety distances between magnets and other items.

What Is Magnetism?
To understand antimagnetic watches, and to be able to compare them as a consumer, you have to know at least a little about what magnetism is, and how it's measured.
Magnetism in everyday life comes from two sources: electromagnets and permanent magnets.
Electromagnets are magnets in which the magnetic field is produced by moving current;
permanent magnets are those which have a magnetic field on their own, without any electric current passing through them.
Both can be hazardous to watches.
It was thought at one time that only certain materials were affected by magnets, but we now know that all materials are affected to some degree.
However, only so-called ferromagnetic materials produce fields strong enough for us to feel in everyday life.
Ferromagnetic materials are those that can be magnetized;
other magnetic interactions are generally too weak to be felt and require laboratory equipment to detect.
Understanding the source of magnetism is easier when you remember that a magnetic field is generated by a changing electrical field.
The opposite is also true;
a changing magnetic field inside a loop of wire will create a current.
This relationship was discovered by Michael Faraday, in 1831 and is the principle behind electrical generators and motors.
If you remember that moving electrical fields generate magnetic fields, you can now understand ferromagnetism.
The electrons present in all materials are in motion, and, as electrons are charged particles, this motion generates a magnetic field.
Electrons have a property known as spin, and usually come in pairs.
Since paired electrons are forbidden by the laws of physics from having the same spin (thanks to something called the Pauli Exclusion Principle ) paired electrons have opposed spins, and so the magnetic fields they generate usually cancel each other out.
- NdFeB, Grade N52
- Dimension: 1/16" dia. x 1/32" thick
- Pull force: 0.07 lbs
However, some materials have unpaired electrons – including iron, which has four in its outermost electron shell – and those unpaired electrons are allowed to have the same spin, which produces a tiny magnetic field, with a specific strength and direction (a vector field, in other words).
In ferromagnetic materials like iron, these tiny fields can be made to line up, and add up, to a field strong enough to be felt.
Put a piece of iron in a strong enough field and the magnetic "domains" inside it will stay lined up even when you take the external field away – you have a permanent magnet.
The most powerful permanent magnets known are so-called rare earth magnets, which can be strong enough to injure you if you're not careful.
(This is a highly simplified model of how magnetism works but it's enough to go on with, as they say.)
Above is a neodymium (rare earth) magnet purchased for the purposes of our informal science experiment.
As it happens I didn't check the field strength of this little beast before ordering it, and I probably should have.
It's quite large, for a neodymium magnet – far bigger than anything you're likely to run into in a consumer product – and once I got it out of the box and found out how much force it took to get it off the door of the refrigerator (both hands, and a very firm tug) I hunted around online until I found an online neodymium magnet strength calculator (truly, everything is on the Internet).
As it turns out a magnet of this size and composition has a surface field strength of over 4,000 gauss, which is a significant fraction of what you'd find in an MRI machine.
It takes 90 pounds of force to pull the thing off a steel plate and if you aren't careful handling it, especially around other ferromagnetic objects, it can move fast enough and hard enough, and connect with enough force, to tear skin or break a finger.
Now the reason I'm (painfully) sticking a wrench to my hand with a 4K gauss magnet is because it's easier to understand how powerful the magnet is from a picture, than from expressing field strength in things like gauss or tesla, which are more abstract.
There are actually two kinds of magnetic fields: B, and H.
The so-called B field is a measure of field strength in free space, and is measured in tesla, or gauss.
One tesla = 10,000 gauss;
a typical refrigerator magnet is about 50 gauss, and our test magnet, at about 4,500 gauss, is nearly half a tesla, which is more than enough to fry any conventional watch.
Obviously, the plain steel balance springs used in watches before the advent of Nivarox type alloys would be incredibly vulnerable to external magnetic fields, but even a watch with a standard modern Nivarox balance spring would be instantly rendered unusable by a magnet as powerful as the one we used in our test.
Even with the high antimagnetic ratings of both the Milgauss and the Omega >15,000 Gauss, the idea of applying such a powerful magnet was a little alarming.
It's one thing to know your car has an air bag;
it's another thing to deliberately run it into a brick wall to find out if it works like it's supposed to.
By the way, you may have heard resistance to magnetism in watches expressed in amperes per meter, sometimes shortened to A/m.
This unit is used to express the strength of the other magnetic field, the so-called H field – as is its equivalent, the oersted.
The H field is basically the strength of the B field, but including its effects inside a material on the overall field.
Fortunately for those of us comparison shopping for antimagnetic watches, in air or a vacuum the B and H fields, and therefore, the gauss and the oersted, are about equal.
The conversion from oersted to A/m is a little more involved but to give a concrete example, the famous IWC antimagnetic Ingenieur 500,000 A/m could resist a field of almost 7,000 oersted/gauss.
A rating of 1,000 gauss resistance is equal to about 80,000 A/m.
As you can see, the B and H fields aren't really different so much as they are the same phenomenon seen from different perspectives.
Fun fact: your brain produces a field of about one picotesla, or 0.000000000001 tesla, which is so weak you need a neat gadget called a SQUID (Subatomic Quantum Interference Detector) to pick it

Due to the extremely small size of these magnets, the magnetic strength is proportionately weaker.
However this means that the magnets can be easily positioned or hidden in objects and tight places!
Gluing these mini magnets are also much more durable as the weaker magnetic pull force is less likely to rip the magnet away from the glued surface even with repeated opening and closing.
Neodymium magnets are the strongest type of permanent magnets available.
Neodymium magnets are permanent magnets, meaning they are able to retain their magnetic strength permanently under normal usage and environment below 80 ° C temperature.
Useful for :
– Small art and craft projects
– Paper crafts
– Mini figurines display and mod
– Model making
– Closure for small box cover
Stack 2 or more pieces if additional strength are required.

Applications for neodymium cube magnets
Neodymium cube magnets are great magnets for pin boards or other magnetic surfaces, the fridge for instance.
The ideal product is a neodymium cube magnet with a 5 mm edge length.
Its adhesive force is sufficient for postcards, notes, photos, etc.
At the same time, the neodymium magnet is small, unobtrusive and does not perforate paper.
For thicker cardboard or posters or for use on a magnetic glass board, we recommend article W-10-N with an extra-high adhesive force.
Many customers also use magnetic cubes for experiments: Simple motors can be built with wire, battery and a strong magnet.
Neodymium magnets are also popular with sculpture buildiers: Thanks to the smooth surfaces, they are easy to arrange in a row or in a block.
If you want to take it a step further, you can make use of the different surface coatings in nickel, copper or gold.
Thanks to its quad shape, neodymium cube magnets can be easily glued to other surfaces.
You can create even larger objects with magnets and attach them to magnetic surfaces.
This list is not comprehensive of course.
Make up your own mind about the versatility of cube magnets and check out some example applications that our satisfied customers shared.
