Engineering analysis of the assembly - technical parameters

The following data are the direct effect of a mathematical simulation. Results are based on models for the material Nd₂Fe₁₄B. Operational conditions may differ. Use these data as a supplementary guide when designing systems.

Grip strength drops sharply with every subsequent millimeter of distance. Keep in mind that even a microscopic distance (e.g., contamination, paint, rust) noticeably diminishes the holding power. Magnetic products work strongest in perfect adhesion; distance drastically cuts the force. See how quickly the parameters fall, when the magnet does not adhere directly to the steel surface. When calculating the arrangement, avoid redundant distances.

The table below indicates the estimated weight limit necessary to initiate the downward movement of the magnet vertically on a upright metal surface (considering typical friction coefficient). This value is relative to the separation distance between the magnet and the surface.

Table 3: Wall mounting (shearing) - behavior on slippery surfaces
MW 10x30 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.58 kg / 1.27 pounds 576.0 g / 5.7 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.38 kg / 0.85 pounds 384.0 g / 3.8 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.19 kg / 0.42 pounds 192.0 g / 1.9 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.96 kg / 2.12 pounds 960.0 g / 9.4 N

When placing a holder on a upright wall (e.g., a fridge), it will only hold only approx. 1/5 of its nominal power. Gravity and a low friction coefficient mean that holders slip faster than they pull off. Designing a hanger? Note that the sliding force is much weaker than the perpendicular breakaway force. On a painted metal, the holder will give way down under a noticeably lighter load. Using a rubber layer can significantly raise the stability.

12 mm	100%	1.92 kg / 4.23 pounds 1920.0 g / 18.8 N

A thin sheet is not enough to absorb the entire magnetic field, which squanders power of the magnet. If you attach a powerful product to a thin surface, the magnetism will pass right through and the pull force will drop sharply. To squeeze 100% of this magnet's potential, you need a suitably thick piece of metal. The saturation phenomenon means that on thin elements (e.g., thin profiles), the holder holds weaker. We advise picking the steel cross-section based on the following data.

Ordinary NdFeB products change their properties strength past the thermal threshold. Protect against heat – excessive heat can irreversibly demagnetize this product. As the temperature rises, the neodymium's capacity temporarily decreases. Refrain from using this magnet near heat sources higher than its working range. Exceeding the critical threshold will cause irreversible degradation of magnetism.

*Engineering note: Thermal stability depends not only on the material grade, as well as the dimension ratios. Low-profile magnets (low permeance coefficient) risk losing magnetic properties under lower heat stress than long magnets. Warning indicator in the table indicates permanent field degradation for this particular item.

Two magnetic products attract each other from a much further distance than a neodymium and metal setup. The connection of magnet-to-magnet produces a massive flux and a wider radius of performance. Planning to create a powerful holder? Utilize two neodymiums instead of one magnet and a striker plate. Be careful that when attracting two neodymiums, the pinch force is extreme. The repulsion force is a bit weaker than the connection force, but still large.
*The magnetic induction for N-N configuration is approximately ~0 Gs in the exact middle between the magnets (resulting from vector opposition).
* Figures refer to friction force of two same magnets (friction ~0.15 for Ni-Ni plating).

Table 7: Safety (HSE) (implants) - warnings
MW 10x30 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	8.5 cm

A strong magnetic field poses a large risk to electronic devices as well as pacemakers. These NdFeB products generate a flux that disrupts operation of sensitive medical devices. Be aware: the invisible magnetic field passes through tissues and glass. Exceptional care must be exercised by people with hearing aids and drug dispensers. Also at risk are: automatic timepieces, car keys, speakers, and displays. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Table 8: Collisions (kinetic energy) - warning
MW 10x30 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	10.58 km/h (2.94 m/s)	0.08 J
30 mm	18.21 km/h (5.06 m/s)	0.23 J
50 mm	23.51 km/h (6.53 m/s)	0.38 J
100 mm	33.24 km/h (9.23 m/s)	0.75 J

Magnetic elements are very brittle – a strong collision with metal can result in shattering. Control the attraction moment – a magnet released freely becomes dangerous. Striking energy can trigger coating fragments or dangerous crushing to fingers. Be sure to control the product during installation so it doesn't slam with momentum against the steel surface. A collision at high speed means shattering of the neodymium. Wear eye protection when playing with powerful specimens.

Corrosion 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. Sliding resistance

*Note: On a vertical wall, the magnet holds merely approx. 20-30% of its nominal pull.

2. Steel saturation

*Thin metal sheet (e.g. computer case) significantly reduces the holding force.

3. Power loss vs temp

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 1.38

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 offered product is a very strong rod magnet, manufactured from durable NdFeB material, which, with dimensions of Ø10x30 mm, guarantees optimal power. This specific item boasts high dimensional repeatability and industrial build quality, making it an ideal solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 1.92 kg), this product is available off-the-shelf from our European logistics center, ensuring rapid order fulfillment. Furthermore, its Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

This model is created for building electric motors, advanced sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the high power of 18.79 N with a weight of only 17.67 g, this cylindrical magnet is indispensable in electronics and wherever every gram matters.

Due to the brittleness of the NdFeB material, we absolutely advise against force-fitting (so-called press-fit), as this risks chipping the coating of this professional component. To ensure stability in industry, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.

Grade N38 is the most popular standard for professional neodymium magnets, offering an optimal price-to-power ratio and high resistance to demagnetization. If you need the strongest magnets in the same volume (Ø10x30), 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 Ø10x30 mm, which, at a weight of 17.67 g, makes it an element with high magnetic energy density. The key parameter here is the lifting capacity amounting to approximately 1.92 kg (force ~18.79 N), which, with such defined dimensions, proves the high grade of the NdFeB material. The product has a [NiCuNi] coating, which secures it against external factors, giving it an aesthetic, silvery shine.

This rod magnet is magnetized axially (along the height of 30 mm), which means that the N and S poles are located on the flat, circular surfaces. Such an arrangement is standard when connecting magnets in stacks (e.g., in filters) or when mounting in sockets at the bottom of a hole. On request, we can also produce versions magnetized through the diameter if your project requires it.

Strengths and weaknesses of Nd₂Fe₁₄B magnets.

Strengths

Besides their exceptional strength, neodymium magnets offer the following advantages:

They do not lose strength, even after around 10 years – the decrease in strength is only ~1% (according to tests),
They are noted for resistance to demagnetization induced by external disturbances,
By applying a reflective coating of silver, the element presents an professional look,
The surface of neodymium magnets generates a strong magnetic field – this is a distinguishing feature,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
Thanks to versatility in designing and the ability to adapt to complex applications,
Universal use in innovative solutions – they serve a role in mass storage devices, motor assemblies, medical devices, and modern systems.
Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which enables their usage in small systems

Disadvantages

Disadvantages of neodymium magnets:

Brittleness is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a special holder, which not only secures them against impacts but also raises their durability
When exposed to high temperature, neodymium magnets suffer a drop in strength. 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 while using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
Limited ability of producing nuts in the magnet and complex shapes - preferred is casing - mounting mechanism.
Potential hazard to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child safety. Furthermore, tiny parts of these devices can be problematic in diagnostics medical when they are in the body.
High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities

Pull force analysis

Maximum lifting force for a neodymium magnet – what affects it?

The specified lifting capacity represents the peak performance, recorded under optimal environment, specifically:

on a block made of mild steel, perfectly concentrating the magnetic field
possessing a thickness of minimum 10 mm to ensure full flux closure
with a plane free of scratches
with direct contact (no impurities)
during pulling in a direction perpendicular to the plane
in temp. approx. 20°C

Practical aspects of lifting capacity – factors

Please note that the magnet holding may be lower subject to the following factors, starting with the most relevant:

Space between surfaces – every millimeter of distance (caused e.g. by varnish or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
Load vector – highest force is obtained only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is typically several times smaller (approx. 1/5 of the lifting capacity).
Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
Material composition – not every steel attracts identically. High carbon content worsen the attraction effect.
Plate texture – smooth surfaces guarantee perfect abutment, which improves force. Uneven metal weaken the grip.
Thermal environment – heating the magnet causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity was assessed with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, however under shearing force the holding force is lower. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.

Precautions when working with NdFeB magnets

Safe operation

Exercise caution. Rare earth magnets attract from a distance and connect with huge force, often quicker than you can react.

Danger to the youngest

Neodymium magnets are not suitable for play. Swallowing several magnets can lead to them connecting inside the digestive tract, which constitutes a severe health hazard and requires immediate surgery.

Material brittleness

Beware of splinters. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.

Combustion hazard

Combustion risk: Neodymium dust is explosive. Avoid machining magnets in home conditions as this may cause fire.

ICD Warning

People with a ICD should keep an safe separation from magnets. The magnetic field can stop the operation of the life-saving device.

Heat sensitivity

Watch the temperature. Heating the magnet above 80 degrees Celsius will permanently weaken its properties and strength.

Hand protection

Big blocks can break fingers instantly. Never place your hand betwixt two strong magnets.

Electronic devices

Equipment safety: Neodymium magnets can ruin data carriers and sensitive devices (heart implants, hearing aids, mechanical watches).

Phone sensors

Remember: neodymium magnets produce a field that interferes with precision electronics. Maintain a safe distance from your mobile, device, and GPS.

Allergic reactions

Studies show that nickel (standard magnet coating) is a potent allergen. For allergy sufferers, avoid touching magnets with bare hands or opt for encased magnets.
