Physical modeling of the magnet - data

The following data constitute the outcome of a physical calculation. Values were calculated on algorithms for the material Nd₂Fe₁₄B. Real-world parameters might slightly differ. Use these data as a preliminary roadmap during assembly planning.

Grip strength decreases sharply per each millimeter of distance. Remember that every additional insulation layer (e.g., contamination, varnish, dust) strongly reduces the pull force. Magnetic products operate most effectively during direct contact; air break drastically cuts the force. See how flashily the pull force plummet, when the product does not adhere flatly to the steel surface. When planning the arrangement, avoid additional spacers.

50 mm	Stal (~0.2)	0.00 kg / 0.00 pounds 0.0 g / 0.0 N

The table below indicates the approximate weight limit necessary to initiate the shifting of the magnet down against a upright steel wall (considering typical friction coefficient). The holding force depends on the air gap between the magnet and the metal.

Table 3: Vertical assembly (sliding) - vertical pull
MW 4x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.14 kg / 0.30 pounds 138.0 g / 1.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.09 kg / 0.20 pounds 92.0 g / 0.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.05 kg / 0.10 pounds 46.0 g / 0.5 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.23 kg / 0.51 pounds 230.0 g / 2.3 N

When placing a holder on a vertical wall (e.g., a fridge), it will maintain only approx. 1/5 of nominal attraction strength. Gravitational force and a low friction coefficient cause that products slide down easier than they detach. Designing a hanger? Consider that the shear force is much weaker than the maximum static pull force. On a slippery surface, the element will give way down under a noticeably lighter cargo. Using a rubber layer can effectively improve the result.

Table 4: Material efficiency (substrate influence) - sheet metal selection
MW 4x5 / N38

Steel thickness (mm)	% power	Real pull force (kg/lbs/g/N)
0.5 mm	10%	0.05 kg / 0.10 pounds 46.0 g / 0.5 N
1 mm	25%	0.12 kg / 0.25 pounds 115.0 g / 1.1 N
2 mm	50%	0.23 kg / 0.51 pounds 230.0 g / 2.3 N
3 mm	75%	0.35 kg / 0.76 pounds 345.0 g / 3.4 N
5 mm	100%	0.46 kg / 1.01 pounds 460.0 g / 4.5 N
10 mm	100%	0.46 kg / 1.01 pounds 460.0 g / 4.5 N
11 mm	100%	0.46 kg / 1.01 pounds 460.0 g / 4.5 N
12 mm	100%	0.46 kg / 1.01 pounds 460.0 g / 4.5 N

A too thin steel is unable to absorb the full magnetic flux, which wastes potential of the holder. If you mount a strong magnet to a weak sheet, the magnetism will pass right through and the attraction force will be weaker. To squeeze full efficiency of this magnet's potential, you require a sufficiently solid element of metal. The saturation effect causes that on thin elements (e.g., car bodies), the magnet holds weaker. We advise picking the steel dimension according to the table below.

Standard neodymium magnets irreversibly lose strength past the thermal threshold. Avoid high temperatures – high temperature can irreversibly damage this magnet. With every degree above norm, the neodymium's power momentarily lowers. Do not use this product close to ovens exceeding its working range. Too high temperature will cause destruction of magnetism.

*Important note: Thermal stability is determined by both grade, but also on the magnet's shape. Flat magnets (low Pc) risk losing magnetic properties under lower heat stress than taller cylinders. Warning indicator in the table signals a risk of irreversible loss for this specific geometry.

Two strong neodymiums interact from a much further distance than a magnet and steel setup. The setup of magnet-to-magnet generates a stronger field and a wider radius of performance. Want to build a strong closure? Apply two magnets instead of a neodymium and a steel. Be careful that when connecting a pair of magnets, the pinch force is huge. The repulsion force is a bit weaker than the connection force, but still significant.
*Flux density for N-N configuration drops to ~0 Gs in the exact middle between the magnets (due to field cancellation).
* Calculations demonstrate sliding force of two identical magnets (friction ~0.15 for Ni-Ni plating).

Table 7: Safety (HSE) (electronics) - precautionary measures
MW 4x5 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	3.0 cm

Extremely neodym field is a serious hazard to electronic devices and pacemakers. These neodymiums produce a field that prevents correct functioning of digital equipment. Be aware: the unseen radiation acts through matter and plastic. Special caution must be taken by people with cochlear implants and insulin pumps. The risk also applies to: automatic timepieces, remotes, membranes, and displays. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

Table 8: Dynamics (kinetic energy) - warning
MW 4x5 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	31.55 km/h (8.76 m/s)	0.02 J
30 mm	54.65 km/h (15.18 m/s)	0.05 J
50 mm	70.55 km/h (19.60 m/s)	0.09 J
100 mm	99.77 km/h (27.71 m/s)	0.18 J

Magnetic elements are very brittle – a collision with steel can result in shattering. Pay attention to connection velocity – a neodymium left loose turns into a projectile. Kinetic force can cause material chips or dangerous crushing to fingers. Be sure to control the product during installation so it doesn't hit with great force against the steel surface. A contact at a velocity of dozens of km/h almost guarantees destruction of the neodymium. Wear eye protection when playing with large magnets.

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

Contrary to myths, water does not block the magnetic field. However, remember the water resistance when pulling the rope quickly.

1. Wall mount (shear)

*Warning: On a vertical wall, the magnet retains just approx. 20-30% of its max power.

2. Efficiency vs thickness

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

3. Heat tolerance

*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) = 1.00

The chart above illustrates the magnetic characteristics of the material within the second quadrant of the hysteresis loop. 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.

This product is an extremely powerful cylinder magnet, made from advanced NdFeB material, which, at dimensions of Ø4x5 mm, guarantees optimal power. This specific item boasts high dimensional repeatability and industrial build quality, making it an excellent solution for the most demanding engineers and designers. As a cylindrical magnet with significant force (approx. 0.46 kg), this product is available off-the-shelf 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, ensuring an aesthetic appearance and durability for years.

This model is created for building electric motors, advanced Hall effect sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the pull force of 4.48 N with a weight of only 0.47 g, this cylindrical magnet is indispensable in electronics 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 two-component epoxy glues. To ensure long-term durability in automation, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.

Magnets N38 are suitable for the majority of applications in modeling and machine building, where excessive miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø4x5), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

The presented product is a neodymium magnet with precisely defined parameters: diameter 4 mm and height 5 mm. The key parameter here is the holding force amounting to approximately 0.46 kg (force ~4.48 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.

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. 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 diametrically if your project requires it.

Pros and cons of Nd₂Fe₁₄B magnets.

Advantages

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

They do not lose strength, even after nearly ten years – the decrease in power is only ~1% (theoretically),
They feature excellent resistance to magnetic field loss when exposed to opposing magnetic fields,
In other words, due to the reflective layer of nickel, the element is aesthetically pleasing,
Magnets have excellent magnetic induction on the surface,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
Thanks to modularity in shaping and the capacity to customize to unusual requirements,
Wide application in electronics industry – they serve a role in hard drives, electric drive systems, advanced medical instruments, and technologically advanced constructions.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Weaknesses

Disadvantages of NdFeB magnets:

To avoid cracks under impact, we recommend using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
Neodymium magnets lose their strength 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. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
Limited possibility of creating nuts in the magnet and complex forms - recommended is cover - mounting mechanism.
Health risk resulting from small fragments of magnets pose a threat, in case of ingestion, which gains importance in the context of child health protection. Additionally, small components of these devices can disrupt the diagnostic process medical after entering the body.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Lifting parameters

Maximum lifting capacity of the magnet – what contributes to it?

The load parameter shown refers to the maximum value, recorded under optimal environment, meaning:

on a base made of mild steel, perfectly concentrating the magnetic flux
possessing a massiveness of min. 10 mm to ensure full flux closure
with an polished touching surface
without any air gap between the magnet and steel
for force acting at a right angle (pull-off, not shear)
at standard ambient temperature

Lifting capacity in practice – influencing factors

It is worth knowing that the working load will differ depending on the following factors, in order of importance:

Gap between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
Angle of force application – highest force is reached only during perpendicular pulling. The force required to slide of the magnet along the surface is usually several times smaller (approx. 1/5 of the lifting capacity).
Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
Steel grade – ideal substrate is pure iron steel. Cast iron may generate lower lifting capacity.
Surface quality – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
Thermal environment – temperature increase causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity was determined using a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, however under attempts to slide the magnet the load capacity is reduced by as much as 75%. Additionally, even a minimal clearance between the magnet and the plate reduces the lifting capacity.

Safe handling of neodymium magnets

Fire risk

Machining of neodymium magnets poses a fire hazard. Neodymium dust reacts violently with oxygen and is difficult to extinguish.

Pinching danger

Pinching hazard: The pulling power is so great that it can result in blood blisters, pinching, and broken bones. Use thick gloves.

Choking Hazard

Product intended for adults. Small elements pose a choking risk, leading to intestinal necrosis. Store away from kids and pets.

Caution required

Be careful. Neodymium magnets attract from a distance and snap with massive power, often quicker than you can move away.

Sensitization to coating

Certain individuals suffer from a hypersensitivity to nickel, which is the typical protective layer for NdFeB magnets. Prolonged contact might lead to an allergic reaction. We strongly advise use safety gloves.

Life threat

Life threat: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.

Protective goggles

Beware of splinters. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. We recommend safety glasses.

Data carriers

Avoid bringing magnets near a purse, computer, or screen. The magnetism can permanently damage these devices and erase data from cards.

Magnetic interference

Navigation devices and mobile phones are extremely sensitive to magnetism. Close proximity with a powerful NdFeB magnet can ruin the sensors in your phone.

Heat warning

Regular neodymium magnets (N-type) lose power when the temperature goes above 80°C. Damage is permanent.
