Technical modeling of the assembly - data

The following information represent the result of a mathematical calculation. Results rely on models for the material Nd₂Fe₁₄B. Real-world parameters may deviate from the simulation results. Please consider these calculations as a reference point for designers.

Pulling power drops sharply with every mm of distance. Remember that even a very thin break (e.g., dirt, paint, rust) noticeably weakens the grip. Magnetic products work most effectively at the point of direct contact; air break weakens the power. Analyze how quickly the load capacity plummet, when the magnet does not touch flatly to the steel surface. When designing the assembly, eliminate additional spacers.

The table below presents the theoretical force required to start the slippage of the magnet vertically along a vertical metal surface (assuming typical friction). This parameter varies with the air gap between the magnet and the surface.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces
MW 4x10 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.10 kg / 0.21 LBS 96.0 g / 0.9 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.06 kg / 0.14 LBS 64.0 g / 0.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.03 kg / 0.07 LBS 32.0 g / 0.3 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.16 kg / 0.35 LBS 160.0 g / 1.6 N

When mounting a magnet on a upright wall (e.g., a board), it will maintain just approx. 20%-30% of its nominal power. Gravitational force and a low friction coefficient influence the fact that magnets slide down faster than they detach. Designing a hanger? Consider that the shear force is significantly lower than the maximum static pull force. On a painted metal, the magnet will slip down under a significantly smaller load. Using a rubber coating can significantly raise the stability.

A too thin steel is incapable of absorb the full magnetic flux, which weakens actual performance of the holder. Should you install a neodymium to a too thin substrate, the flux will penetrate right through and the attraction force will be weaker. To utilize the maximum of this neodymium's potential, you require a sufficiently solid element of steel. The material oversaturation means that on thin elements (e.g., car bodies), the magnet works worse. We recommend selecting the steel dimension according to the table below.

Classic neodymiums change their properties power after exceeding the maximum temperature. Avoid high temperatures – excessive heat can permanently damage this product. With every degree above norm, the neodymium's force momentarily decreases. Refrain from using this product in hot environments exceeding its working range. Exceeding the critical threshold will result in destruction of magnetism.

*Technical advisory: Temperature resistance is determined by both grade, as well as the dimension ratios. Low-profile magnets (low Pc) risk losing magnetic properties sooner than long magnets. The danger warning in the table points to permanent field degradation for this specific geometry.

Two magnets interact from a wider radius than a neodymium and metal combination. The connection of magnet-to-magnet creates a more powerful interaction and a larger range of action. Designing a solid fastener? Utilize two neodymiums instead of a neodymium and a steel. Remember that when connecting a pair of magnets, the impact force is extreme. The levitation is slightly lower than the connection force, but still impressive.
*Field value in repulsion mode drops to ~0 Gs at the geometric center between the magnets (caused by magnetic field nullification).
* Figures demonstrate friction force of dual matching neodymium magnets (friction ~0.15 for Ni-Ni layer).

Powerful magnet radiation poses a serious hazard to electronics and medical implants. These magnets generate a field that destroys function of sensitive medical devices. Be aware: the invisible magnetic field passes through tissues and glass. Exceptional care must be taken by people with cochlear implants and insulin pumps. Influence will be felt by: mechanical watches, car keys, membranes, and displays. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

NdFeB products are prone to chipping – a violent impact against metal can result in shattering. Watch the impact speed – a magnet released freely speeds with massive force. Impact energy can destroy the magnet or injury to fingers. Always hold the magnet during mounting so it doesn't slam with momentum against the metal. A contact at a velocity of dozens of km/h ends with a crack of the magnet. Wear eye protection when handling with large magnets.

Corrosion warning: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

In water, the magnet feels stronger thanks to Archimedes' principle. Buoyancy helps in lifting finds.

1. Shear force

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

2. Plate thickness effect

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

3. Heat tolerance

*For standard magnets, the critical limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 1.31

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 an exceptionally strong rod magnet, made from modern NdFeB material, which, with dimensions of Ø4x10 mm, guarantees optimal power. This specific item boasts high dimensional repeatability and professional build quality, making it an ideal solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 0.32 kg), this product is in stock from our warehouse in Poland, ensuring lightning-fast order fulfillment. Furthermore, its Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

It finds application in modeling, advanced automation, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 3.16 N with a weight of only 0.94 g, this cylindrical magnet is indispensable in miniature devices and wherever low weight is crucial.

Since our magnets have a very precise dimensions, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 4.1 mm) using epoxy glues. To ensure stability in industry, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.

Magnets N38 are strong enough for 90% of applications in automation and machine building, where excessive miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø4x10), 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 Ø4x10 mm, which, at a weight of 0.94 g, makes it an element with impressive magnetic energy density. The key parameter here is the holding force amounting to approximately 0.32 kg (force ~3.16 N), which, with such compact dimensions, proves the high grade of the NdFeB material. The product has a [NiCuNi] coating, which protects the surface against oxidation, giving it an aesthetic, silvery shine.

Standardly, the magnetic axis runs through the center of the cylinder, causing the greatest attraction force to occur on the bases with a diameter of 4 mm. 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.

Pros and cons of Nd₂Fe₁₄B magnets.

Benefits

In addition to their long-term stability, neodymium magnets provide the following advantages:

They virtually do not lose strength, because even after ten years the decline in efficiency is only ~1% (according to literature),
Neodymium magnets are distinguished by highly resistant to demagnetization caused by external interference,
Thanks to the reflective finish, the plating of nickel, gold-plated, or silver-plated gives an elegant appearance,
Neodymium magnets generate maximum magnetic induction on a small area, which allows for strong attraction,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
Possibility of detailed forming as well as optimizing to specific applications,
Versatile presence in electronics industry – they are utilized in magnetic memories, brushless drives, diagnostic systems, as well as industrial machines.
Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which enables their usage in compact constructions

Cons

Disadvantages of neodymium magnets:

At strong impacts they can crack, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
Neodymium magnets decrease their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
Limited ability of creating threads in the magnet and complex shapes - recommended is a housing - magnet mounting.
Health risk to health – tiny shards of magnets are risky, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Additionally, tiny parts of these magnets are able to disrupt the diagnostic process medical after entering the body.
With mass production the cost of neodymium magnets is a challenge,

Holding force characteristics

Maximum lifting capacity of the magnet – what affects it?

Holding force of 0.32 kg is a result of laboratory testing performed under standard conditions:

with the contact of a sheet made of low-carbon steel, ensuring full magnetic saturation
whose transverse dimension equals approx. 10 mm
with an ideally smooth contact surface
under conditions of ideal adhesion (surface-to-surface)
during pulling in a direction perpendicular to the plane
in temp. approx. 20°C

What influences lifting capacity in practice

It is worth knowing that the magnet holding will differ subject to the following factors, in order of importance:

Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
Load vector – highest force is available only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is typically many times lower (approx. 1/5 of the lifting capacity).
Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
Material composition – different alloys reacts the same. High carbon content worsen the interaction with the magnet.
Smoothness – full contact is possible only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
Temperature influence – hot environment weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.

Lifting capacity was assessed by applying a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under shearing force the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate lowers the holding force.

H&S for magnets

GPS Danger

A strong magnetic field negatively affects the operation of compasses in phones and GPS navigation. Keep magnets near a smartphone to prevent breaking the sensors.

Warning for allergy sufferers

Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction happens, cease working with magnets and use protective gear.

Life threat

Individuals with a pacemaker must keep an safe separation from magnets. The magnetic field can interfere with the operation of the implant.

Fragile material

NdFeB magnets are ceramic materials, which means they are fragile like glass. Clashing of two magnets leads to them cracking into shards.

Choking Hazard

These products are not suitable for play. Accidental ingestion of multiple magnets can lead to them pinching intestinal walls, which constitutes a severe health hazard and requires urgent medical intervention.

Bone fractures

Risk of injury: The attraction force is so great that it can result in hematomas, pinching, and broken bones. Protective gloves are recommended.

Handling guide

Be careful. Neodymium magnets attract from a long distance and snap with massive power, often faster than you can react.

Protect data

Device Safety: Neodymium magnets can ruin data carriers and sensitive devices (heart implants, medical aids, timepieces).

Fire risk

Machining of NdFeB material poses a fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.

Heat warning

Regular neodymium magnets (N-type) lose power when the temperature surpasses 80°C. This process is irreversible.
