Magnetic force decreases sharply with every subsequent millimeter of gap. Note that even a very thin break (e.g., dirt, varnish, dust) strongly diminishes the holding power. Magnetic products hold strongest at the point of direct contact; distance nullifies the power. Observe how flashily the load capacity plummet, when the magnet does not touch flatly to the steel surface. When calculating the mounting, discard unnecessary gaps.

The following data defines the estimated holding capacity required to initiate the downward movement of the magnet vertically against a vertical metal surface (considering standard friction). The holding force depends on the gap size between the magnet and the surface.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces
MW 20x1.5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.29 kg / 0.64 lbs 291.0 g / 2.9 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.19 kg / 0.43 lbs 194.0 g / 1.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.10 kg / 0.21 lbs 97.0 g / 1.0 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.49 kg / 1.07 lbs 485.0 g / 4.8 N

When mounting a holder on a vertical surface (e.g., a car body), it will only hold just about 20%-30% of its maximum pull force. Gravitational force as well as a low friction coefficient mean that holders slip faster than they pop off the substrate. Planning a vertical fastening? Remember that the sliding force is much weaker than the maximum static pull force. On a painted metal, the magnet will give way down under a significantly smaller cargo. Using a rubber layer can significantly raise the stability.

A thin metal plate is unable to take in the full magnetic flux, which wastes potential of the magnet. If you mount a strong magnet to a thin surface, the field will pass right through and the attraction force will be weaker. To achieve 100% of this magnet's potential, you require a sufficiently solid backing of steel. The saturation effect causes that on delicate walls (e.g., appliance housings), the magnet shows lower pull force. We advise picking the steel dimension from these parameters.

Classic neodymiums lose strength above the temperature limit. Watch out for overheating – excessive heat can permanently demagnetize this product. As the temperature rises, the magnet's power temporarily drops. Refrain from using this product near heat sources exceeding its safe range. Exceeding the critical threshold will lead to destruction of magnetic properties.

*Technical advisory: Thermal stability depends not only on the material grade, and the Permeance Coefficient Pc. Low-profile magnets (low permeance coefficient) risk losing magnetic properties under lower heat stress than taller cylinders. Red status in the table signals permanent field degradation for this particular item.

Two magnets interact from a significantly greater distance than a magnet and steel setup. The setup of two magnets produces a massive flux and a wider radius of operation. Want to build a strong closure? Utilize two neodymiums instead of one magnet and a striker plate. Remember that when connecting a pair of magnets, the pinch force is extreme. The levitation is a bit weaker than the attraction, but still large.
*Field value between like poles drops to ~0 Gs at the midpoint between the magnets (resulting from vector opposition).
Important: Calculations show sliding force of a pair of identical magnets (friction coefficient ~0.15 for Ni-Ni layer).

Powerful magnet radiation is a serious hazard to electronic devices as well as pacemakers. These neodymiums produce a field that disrupts operation of digital equipment. Remember: the unseen radiation passes through tissues and plastic. Special caution must be taken by people with cochlear implants and insulin pumps. Also at risk are: mechanical watches, car keys, speakers, and displays. Do not bring the product near payment cards, HDD media, or precise measuring instruments.

Magnetic elements are prone to chipping – a strong collision with metal causes immediate chipping. Watch the impact speed – a neodymium left loose becomes dangerous. Striking energy can destroy the magnet or dangerous crushing to skin. Be sure to control the product during installation 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. Use safety goggles when handling with large magnets.

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

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

1. Vertical hold

*Warning: On a vertical surface, the magnet holds just a fraction of its perpendicular strength.

2. Steel saturation

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

3. Heat tolerance

*For N38 material, the max working temp is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.12

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 a very strong cylindrical magnet, manufactured from advanced NdFeB material, which, at dimensions of Ø20x1.5 mm, guarantees maximum efficiency. This specific item is characterized by high dimensional repeatability and professional build quality, making it a perfect solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 0.97 kg), this product is available off-the-shelf from our European logistics center, ensuring quick order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

This model is perfect for building electric motors, advanced sensors, and efficient magnetic separators, where field concentration on a small surface counts. Thanks to the high power of 9.50 N with a weight of only 3.53 g, this cylindrical magnet is indispensable in electronics and wherever every gram matters.

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 long-term durability in automation, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.

Magnets N38 are strong enough 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 (Ø20x1.5), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.

This model is characterized by dimensions Ø20x1.5 mm, which, at a weight of 3.53 g, makes it an element with high magnetic energy density. The key parameter here is the holding force amounting to approximately 0.97 kg (force ~9.50 N), which, with such compact 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 20 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 rare earth magnets.

Pros

Besides their immense pulling force, neodymium magnets offer the following advantages:

Their power is maintained, and after approximately ten years it drops only by ~1% (according to research),
They are resistant to demagnetization induced by external field influence,
In other words, due to the aesthetic layer of nickel, the element gains visual value,
The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
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...
Thanks to versatility in constructing and the ability to adapt to specific needs,
Versatile presence in modern technologies – they are used in hard drives, motor assemblies, medical devices, also multitasking production systems.
Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which makes them useful in compact constructions

Limitations

Disadvantages of neodymium magnets:

They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
Neodymium magnets decrease their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
Due to limitations in realizing threads and complicated forms in magnets, we recommend using a housing - magnetic holder.
Possible danger related to microscopic parts of magnets can be dangerous, if swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small components of these products can disrupt the diagnostic process medical in case of swallowing.
With large orders the cost of neodymium magnets is a challenge,

Holding force characteristics

Detachment force of the magnet in optimal conditions – what affects it?

Information about lifting capacity is the result of a measurement for ideal contact conditions, including:

with the use of a sheet made of special test steel, ensuring maximum field concentration
with a thickness no less than 10 mm
with an ground contact surface
under conditions of ideal adhesion (surface-to-surface)
under perpendicular force direction (90-degree angle)
at room temperature

Impact of factors on magnetic holding capacity in practice

In practice, the actual holding force results from many variables, presented from most significant:

Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
Material type – the best choice is high-permeability steel. Cast iron may attract less.
Surface quality – the more even the plate, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
Operating temperature – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and in frost gain strength (up to a certain limit).

Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under perpendicular forces, whereas under parallel forces the holding force is lower. Moreover, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.

Precautions when working with neodymium magnets

Keep away from electronics

A strong magnetic field interferes with the functioning of magnetometers in phones and GPS navigation. Keep magnets near a smartphone to avoid damaging the sensors.

Immense force

Be careful. Rare earth magnets act from a distance and connect with huge force, often faster than you can react.

No play value

NdFeB magnets are not suitable for play. Swallowing a few magnets can lead to them attracting across intestines, which constitutes a direct threat to life and requires urgent medical intervention.

Hand protection

Large magnets can smash fingers instantly. Do not place your hand betwixt two strong magnets.

Pacemakers

For implant holders: Strong magnetic fields affect electronics. Maintain minimum 30 cm distance or ask another person to handle the magnets.

Power loss in heat

Standard neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. Damage is permanent.

Electronic hazard

Avoid bringing magnets close to a purse, laptop, or screen. The magnetic field can irreversibly ruin these devices and wipe information from cards.

Combustion hazard

Drilling and cutting of neodymium magnets carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.

Eye protection

Despite metallic appearance, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.

Allergy Warning

Medical facts indicate that the nickel plating (standard magnet coating) is a potent allergen. For allergy sufferers, refrain from direct skin contact and opt for encased magnets.
