Technical analysis of the magnet - data

The following data represent the result of a engineering simulation. Results are based on algorithms for the class Nd₂Fe₁₄B. Operational parameters might slightly differ from theoretical values. Treat these calculations as a reference point when designing systems.

Table 1: Static force (pull vs distance) - power drop
MW 10x10 / N38

Pulling power drops significantly with every subsequent millimeter of distance. Note that even a very thin break (e.g., contamination, paint, dust) significantly weakens the grip. Magnets hold strongest in perfect adhesion; distance kills the force. See how rapidly the load capacity plummet, when the product does not touch tightly to the steel surface. When calculating the arrangement, avoid redundant distances.

This section presents the theoretical weight limit required to initiate the slippage of the magnet downwards against a vertical metal surface (assuming typical friction). The holding force is a function of the air gap between the magnet and the surface.

Table 3: Vertical assembly (shearing) - vertical pull
MW 10x10 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.95 kg / 954.0 g 9.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.64 kg / 636.0 g 6.2 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.32 kg / 318.0 g 3.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.59 kg / 1590.0 g 15.6 N

When hanging a element on a upright plane (e.g., a car body), it will only hold barely about 20%-30% of its nominal power. Gravity as well as a weak degree of grip mean that products slip easier than they pop off the substrate. Designing a wall mount? Consider that the sliding force is noticeably lower than the maximum static pull force. On a slippery surface, the magnet will slip down under a noticeably lighter load. Utilizing a rubberized pad can significantly increase the grip.

Table 4: Steel thickness (substrate influence) - sheet metal selection
MW 10x10 / N38

Steel thickness (mm)	% power	Real pull force (kg)
0.5 mm	10%	0.32 kg / 318.0 g 3.1 N
1 mm	25%	0.80 kg / 795.0 g 7.8 N
2 mm	50%	1.59 kg / 1590.0 g 15.6 N
5 mm	100%	3.18 kg / 3180.0 g 31.2 N
10 mm	100%	3.18 kg / 3180.0 g 31.2 N

A thin metal plate is not enough to focus the full magnetic flux, which squanders power of the holder. Should you attach a powerful product to a thin surface, the magnetism will penetrate right through and the pull force will drop sharply. To squeeze full efficiency of this magnet's power, you require a sufficiently solid piece of steel. The saturation effect causes that on delicate walls (e.g., thin profiles), the holder works worse. We advise picking the steel cross-section according to the table below.

Table 5: Working in heat (stability) - thermal limit
MW 10x10 / N38

Ambient temp. (°C)	Power loss	Remaining pull	Status
20 °C	0.0%	3.18 kg / 3180.0 g 31.2 N	OK
40 °C	-2.2%	3.11 kg / 3110.0 g 30.5 N	OK
60 °C	-4.4%	3.04 kg / 3040.1 g 29.8 N	OK
80 °C	-6.6%	2.97 kg / 2970.1 g 29.1 N
100 °C	-28.8%	2.26 kg / 2264.2 g 22.2 N

Classic neodymiums change their properties power after exceeding the maximum temperature. Watch out for overheating – heat can permanently destroy this magnet. As the temperature rises, the magnet's capacity briefly decreases. Do not use this product in hot environments higher than its safe range. Too high temperature will lead to destruction of magnetism.

*Technical advisory: Heat tolerance depends not only on the material grade, as well as the dimension ratios. Low-profile magnets (low permeance coefficient) may lose charge permanently sooner than long magnets. Red status in the table points to permanent field degradation for this specific geometry.

Two magnets interact from a wider radius than a magnet and sheet setup. The setup of two magnets generates a stronger field and a wider radius of action. Want to build a solid fastener? Use a pair of magnets instead of one magnet and a steel. Remember that when bringing together two magnets, the collision energy is massive. The levitation is slightly lower than the attraction, but still significant.
*The magnetic induction in repulsion mode is approximately ~0 Gs in the exact middle between the magnets (due to field cancellation).

A strong magnetic field poses a serious hazard to electronics and medical implants. These neodymiums generate a flux that prevents correct functioning of sensitive medical devices. Notice: the invisible magnetic field acts through matter and glass. Exceptional care must be exercised by people with hearing aids and insulin pumps. The risk also applies to: automatic timepieces, remotes, membranes, and displays. Do not bring the product near payment cards, HDD media, or precise measuring instruments.

NdFeB products are prone to chipping – a strong collision with metal risks their cracking. Control the attraction moment – a neodymium left loose turns into a projectile. Kinetic force can trigger coating fragments or dangerous crushing to fingers. Always hold the magnet during mounting so it doesn't hit violently against the metal. A collision at high speed ends with a crack of the magnet. Wear safety glasses when working with large magnets.

Warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

The magnetic field penetrates through water without any losses. Buoyancy helps in lifting finds.

1. Shear force

*Caution: On a vertical wall, the magnet retains just a fraction of its perpendicular strength.

2. Efficiency vs thickness

*Thin steel (e.g. computer case) severely weakens the holding force.

3. Thermal stability

*For N38 grade, the critical limit is 80°C.

4. Demagnetization curve and operating point (B-H)

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.89

This simulation demonstrates the magnetic stability of the selected magnet under specific geometric conditions. The solid red line represents the demagnetization curve (material potential), while the dashed blue line is the load line based on the magnet's geometry. The P_c (Permeance Coefficient), also known as the load line slope, is a dimensionless value that describes the relationship between the magnet's shape and its magnetic stability. The intersection of these two lines (the black dot) is the operating point — it determines the actual magnetic flux density generated by the magnet in this specific configuration. A higher P_c value means the magnet is more 'slender' (tall relative to its area), resulting in a higher operating point and better resistance to irreversible demagnetization caused by external fields or temperature. A value of 0.42 is relatively low (typical for flat magnets), meaning the operating point is closer to the 'knee' of the curve — caution is advised when operating at temperatures near the maximum limit to avoid strength loss.

The presented product is a very strong cylindrical magnet, produced from durable NdFeB material, which, with dimensions of Ø10x10 mm, guarantees the highest energy density. The MW 10x10 / N38 component is characterized by an accuracy of ±0.1mm and industrial build quality, making it an ideal solution for the most demanding engineers and designers. As a magnetic rod with significant force (approx. 3.18 kg), this product is in stock from our warehouse in Poland, ensuring rapid order fulfillment. Additionally, its Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

It finds application in DIY projects, advanced robotics, and broadly understood industry, serving as a fastening or actuating element. Thanks to the high power of 31.15 N with a weight of only 5.89 g, this rod is indispensable in miniature devices and wherever low weight is crucial.

Due to the brittleness of the NdFeB material, we absolutely advise against force-fitting (so-called press-fit), as this risks immediate cracking of this precision component. To ensure long-term durability in industry, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.

Magnets NdFeB grade N38 are suitable for the majority of applications in modeling and machine building, where extreme miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø10x10), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.

This model is characterized by dimensions Ø10x10 mm, which, at a weight of 5.89 g, makes it an element with impressive magnetic energy density. The value of 31.15 N means that the magnet is capable of holding a weight many times exceeding its own mass of 5.89 g. The product has a [NiCuNi] coating, which protects the surface against oxidation, giving it an aesthetic, silvery shine.

This rod magnet is magnetized axially (along the height of 10 mm), which means that the N and S poles are located on the flat, circular surfaces. Thanks to this, the magnet can be easily glued into a hole and achieve a strong field on the front surface. On request, we can also produce versions magnetized through the diameter if your project requires it.

Advantages as well as disadvantages of rare earth magnets.

Pros

Apart from their notable holding force, neodymium magnets have these key benefits:

They retain magnetic properties for almost ten years – the drop is just ~1% (according to analyses),
They have excellent resistance to weakening of magnetic properties as a result of external magnetic sources,
By using a lustrous coating of silver, the element has an proper look,
The surface of neodymium magnets generates a intense magnetic field – this is one of their assets,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
Possibility of precise shaping and modifying to precise applications,
Fundamental importance in innovative solutions – they serve a role in hard drives, electromotive mechanisms, precision medical tools, and technologically advanced constructions.
Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,

Cons

Disadvantages of NdFeB magnets:

At strong impacts they can crack, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
Limited possibility of producing threads in the magnet and complicated shapes - preferred is casing - magnetic holder.
Potential hazard resulting from small fragments of magnets are risky, if swallowed, which gains importance in the context of child health protection. Furthermore, tiny parts of these devices can be problematic in diagnostics medical in case of swallowing.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities

Lifting parameters

Highest magnetic holding force – what contributes to it?

The lifting capacity listed is a measurement result performed under standard conditions:

on a block made of mild steel, effectively closing the magnetic field
possessing a thickness of minimum 10 mm to avoid saturation
with an ideally smooth contact surface
under conditions of no distance (surface-to-surface)
under axial force vector (90-degree angle)
at standard ambient temperature

Determinants of practical lifting force of a magnet

Real force is affected by specific conditions, such as (from priority):

Air gap (betwixt the magnet and the plate), since even a tiny distance (e.g. 0.5 mm) can cause a reduction in force by up to 50% (this also applies to varnish, corrosion or dirt).
Force direction – catalog parameter refers to pulling vertically. When applying parallel force, the magnet holds much less (often approx. 20-30% of nominal force).
Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
Steel grade – ideal substrate is high-permeability steel. Hardened steels may generate lower lifting capacity.
Surface structure – the more even the plate, the better the adhesion and stronger the hold. Roughness creates an air distance.
Thermal environment – temperature increase causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under perpendicular forces, whereas under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate decreases the holding force.

Precautions when working with NdFeB magnets

Warning for allergy sufferers

Some people have a sensitization to Ni, which is the standard coating for NdFeB magnets. Extended handling can result in an allergic reaction. We recommend wear safety gloves.

Bodily injuries

Protect your hands. Two powerful magnets will join instantly with a force of massive weight, crushing anything in their path. Exercise extreme caution!

Do not give to children

These products are not intended for children. Swallowing a few magnets can lead to them attracting across intestines, which constitutes a direct threat to life and requires immediate surgery.

Life threat

For implant holders: Strong magnetic fields affect electronics. Maintain minimum 30 cm distance or request help to work with the magnets.

Caution required

Handle with care. Rare earth magnets attract from a long distance and connect with massive power, often faster than you can react.

Eye protection

Despite the nickel coating, the material is brittle and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.

Heat warning

Control the heat. Exposing the magnet to high heat will ruin its properties and pulling force.

Machining danger

Combustion risk: Rare earth powder is explosive. Do not process magnets without safety gear as this risks ignition.

Precision electronics

GPS units and mobile phones are extremely susceptible to magnetic fields. Close proximity with a strong magnet can decalibrate the sensors in your phone.

Electronic hazard

Intense magnetic fields can corrupt files on credit cards, HDDs, and other magnetic media. Stay away of at least 10 cm.
