Magnetic force drops significantly with every mm of distance. Note that even the smallest gap (e.g., dirt, varnish, veneer) significantly weakens the grip. Magnetic products operate most effectively in perfect adhesion; air break nullifies the power. Observe how rapidly the load capacity fall, when the magnet does not adhere flatly to the steel surface. When planning the arrangement, eliminate unnecessary gaps.

This section calculates the theoretical holding capacity needed to cause the slippage of the magnet down on a vertical steel plate (assuming standard friction). The holding force depends on the air gap between the magnet and the metal.

Table 3: Wall mounting (shearing) - vertical pull
MW 8x15 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.44 kg / 441.0 g 4.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.29 kg / 294.0 g 2.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.15 kg / 147.0 g 1.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.74 kg / 735.0 g 7.2 N

When mounting a holder on a upright plane (e.g., a car body), it will maintain just about 1/5 of its nominal power. Gravity as well as a low friction coefficient mean that holders slip faster than they detach. Designing a wall mount? Consider that the shear force is much weaker than the perpendicular breakaway force. On a painted metal, the holder will slide down under a noticeably lighter weight. Utilizing a rubberized coating can significantly improve the result.

Table 4: Material efficiency (saturation) - sheet metal selection
MW 8x15 / N38

Steel thickness (mm)	% power	Real pull force (kg)
0.5 mm	10%	0.15 kg / 147.0 g 1.4 N
1 mm	25%	0.37 kg / 367.5 g 3.6 N
2 mm	50%	0.74 kg / 735.0 g 7.2 N
5 mm	100%	1.47 kg / 1470.0 g 14.4 N
10 mm	100%	1.47 kg / 1470.0 g 14.4 N

A too thin steel cannot absorb the entire magnetic field, which squanders power of the magnet. Should you mount a strong magnet to a weak sheet, the magnetism will penetrate right through and the pull force will drop sharply. To utilize the maximum of this magnet's potential, you require a sufficiently solid backing of steel. The saturation phenomenon causes that on delicate walls (e.g., thin profiles), the holder holds weaker. We advise picking the steel cross-section according to the table below.

100 °C	-28.8%	1.05 kg / 1046.6 g 10.3 N

Ordinary NdFeB products irreversibly lose power above the temperature limit. Protect against heat – heat can permanently damage this magnet. As the temperature rises, the neodymium's capacity briefly lowers. Refrain from using this magnet near heat sources higher than its working range. Exceeding the critical threshold will result in irreversible degradation of magnetism.

*Important note: Thermal stability is determined by both grade, as well as the dimension ratios. Low-profile magnets (low Pc) may lose charge permanently at lower temperatures compared to rod magnets. The danger warning in the table indicates permanent field degradation for this particular item.

Two magnetic products interact from a significantly greater distance than a neodymium and metal combination. The connection of two magnets creates a more powerful interaction and a wider radius of performance. Designing a solid fastener? Utilize two neodymiums instead of one magnet and a striker plate. Be careful that when attracting two neodymiums, the collision energy is extreme. The repulsion force is marginally weaker than the connection force, but still significant.
*Flux density for N-N configuration reaches ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).

A strong magnetic field poses a large risk to IT equipment and medical implants. These magnets generate a field that prevents correct functioning of sensitive medical devices. Notice: the unseen radiation penetrates the body and housings. Increased vigilance must be taken by people with hearing aids and insulin pumps. The risk also applies to: mechanical watches, car keys, membranes, and displays. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

100 mm	51.44 km/h (14.29 m/s)	0.58 J

Magnetic elements are prone to chipping – a collision with steel risks their cracking. Watch the impact speed – a magnet released freely turns into a projectile. Impact energy can destroy the magnet or injury to fingers. Be sure to control the product during installation so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h means shattering of the neodymium. Use safety goggles when working with powerful specimens.

Corrosion warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

Water displaces steel, making heavy objects slightly lighter. However, remember the water resistance when pulling the rope quickly.

1. Sliding resistance

*Note: On a vertical wall, the magnet holds only approx. 20-30% of its perpendicular strength.

2. Steel thickness impact

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

3. Power loss vs temp

*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) = 1.19

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.

The offered product is a very strong rod magnet, composed of durable NdFeB material, which, at dimensions of Ø8x15 mm, guarantees optimal power. This specific item 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 cylindrical magnet with significant force (approx. 1.47 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring rapid order fulfillment. Furthermore, its Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is ideal for building electric motors, advanced sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the high power of 14.45 N with a weight of only 5.65 g, this cylindrical magnet is indispensable in electronics and wherever low weight is crucial.

Due to the brittleness of the NdFeB material, you must not use force-fitting (so-called press-fit), as this risks chipping the coating of this professional component. To ensure stability in industry, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.

Grade N38 is the most frequently chosen standard for industrial neodymium magnets, offering an optimal price-to-power ratio and operational stability. If you need the strongest magnets in the same volume (Ø8x15), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

This model is characterized by dimensions Ø8x15 mm, which, at a weight of 5.65 g, makes it an element with high magnetic energy density. The key parameter here is the holding force amounting to approximately 1.47 kg (force ~14.45 N), which, with such defined dimensions, proves the high power of the NdFeB material. The product has a [NiCuNi] coating, which protects the surface 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 8 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 diametrically if your project requires it.

Pros as well as cons of Nd₂Fe₁₄B magnets.

Advantages

Besides their durability, neodymium magnets are valued for these benefits:

They do not lose power, even during nearly 10 years – the reduction in lifting capacity is only ~1% (theoretically),
They maintain their magnetic properties even under strong external field,
A magnet with a metallic gold surface has an effective appearance,
They show high magnetic induction at the operating surface, making them more effective,
Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
Possibility of custom machining and adjusting to individual needs,
Wide application in modern technologies – they are commonly used in computer drives, electromotive mechanisms, precision medical tools, as well as industrial machines.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Weaknesses

Disadvantages of neodymium magnets:

Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a steel housing, which not only secures them against impacts but also raises their durability
We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
Magnets exposed to a humid environment can rust. Therefore when using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
Due to limitations in producing threads and complex shapes in magnets, we propose using casing - magnetic mechanism.
Possible danger to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child safety. It is also worth noting that small components of these magnets are able to disrupt the diagnostic process medical in case of swallowing.
With mass production the cost of neodymium magnets is a challenge,

Pull force analysis

Magnetic strength at its maximum – what affects it?

Holding force of 1.47 kg is a theoretical maximum value executed under the following configuration:

with the use of a yoke made of low-carbon steel, guaranteeing maximum field concentration
with a cross-section of at least 10 mm
with a plane free of scratches
with zero gap (no impurities)
for force applied at a right angle (pull-off, not shear)
at standard ambient temperature

Determinants of practical lifting force of a magnet

Holding efficiency is affected by working environment parameters, including (from priority):

Distance (between the magnet and the metal), because even a very small distance (e.g. 0.5 mm) leads to a reduction in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
Load vector – maximum parameter is available only during perpendicular pulling. The shear force of the magnet along the surface is standardly many times lower (approx. 1/5 of the lifting capacity).
Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
Material type – ideal substrate is high-permeability steel. Hardened steels may attract less.
Smoothness – ideal contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
Temperature – temperature increase results in weakening of force. It is worth remembering the thermal limit for a given model.

Lifting capacity was assessed using a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular pulling force, in contrast under parallel forces the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate reduces the holding force.

Precautions when working with NdFeB magnets

Handling rules

Before starting, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Be predictive.

Adults only

Always keep magnets out of reach of children. Ingestion danger is high, and the effects of magnets clamping inside the body are tragic.

Bone fractures

Pinching hazard: The attraction force is so immense that it can cause hematomas, crushing, and broken bones. Protective gloves are recommended.

Warning for heart patients

Life threat: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.

Beware of splinters

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

Dust explosion hazard

Mechanical processing of neodymium magnets poses a fire risk. Neodymium dust reacts violently with oxygen and is hard to extinguish.

Safe distance

Data protection: Neodymium magnets can ruin data carriers and sensitive devices (pacemakers, hearing aids, timepieces).

Operating temperature

Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will ruin its properties and pulling force.

Nickel coating and allergies

Studies show that the nickel plating (standard magnet coating) is a strong allergen. For allergy sufferers, avoid touching magnets with bare hands or choose encased magnets.

GPS Danger

An intense magnetic field disrupts the functioning of magnetometers in phones and navigation systems. Maintain magnets near a device to prevent breaking the sensors.
