Pulling power drops drastically with every mm of spacing. Note that even a very thin break (e.g., dirt, varnish, dust) significantly reduces the pull force. Magnetic products operate optimally at the point of direct contact; distance weakens the force. Observe how rapidly the pull force plummet, when the magnet does not adhere directly to the steel surface. When calculating the arrangement, avoid additional spacers.

The table below indicates the theoretical force needed to start the slippage of the magnet down on a upright steel plate (considering typical friction coefficient). The holding force depends on the gap size between the magnet and the metal.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MW 14.9x10 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	2.28 kg / 5.03 LBS 2280.0 g / 22.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.52 kg / 3.35 LBS 1520.0 g / 14.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.76 kg / 1.68 LBS 760.0 g / 7.5 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	3.80 kg / 8.38 LBS 3800.0 g / 37.3 N

When mounting a holder on a upright plane (e.g., a car body), it will only hold only about 20%-30% of its maximum pull force. Gravitational force and a low friction coefficient cause that magnets slip faster than they pull off. Designing a vertical fastening? Note that the sliding force is significantly lower than the perpendicular breakaway force. On a painted metal, the element will slide down under a much lighter load. Utilizing a rubberized pad can drastically improve the result.

12 mm	100%	7.60 kg / 16.76 LBS 7600.0 g / 74.6 N

A thin sheet is not enough to take in the full magnetic flux, which squanders power of the magnet. If you mount a strong magnet to a too thin substrate, the flux will pass right through and the holding will be smaller. To achieve full efficiency of this neodymium's potential, you need a suitably thick backing of steel. The saturation phenomenon causes that on thin elements (e.g., appliance housings), the product shows lower pull force. We advise picking the steel cross-section according to the table below.

Table 5: Thermal stability (stability) - resistance threshold

Ambient temp. (°C)	Power loss	Remaining pull (kg/lbs/g/N)	Status

100 °C	-28.8%	5.41 kg / 11.93 LBS 5411.2 g / 53.1 N

Ordinary NdFeB products lose strength past the thermal threshold. Avoid high temperatures – high temperature can permanently destroy this product. With increasing heat, the magnet's power temporarily drops. Do not use this product near heat sources higher than its operating temperature limit. Ignoring the limit will result in destruction of magnetic properties.

*Technical advisory: Temperature resistance depends not only on the material grade, and the Permeance Coefficient Pc. Thin magnets (low Pc) risk losing magnetic properties sooner than long magnets. Red status in the table indicates a risk of irreversible loss for this specific geometry.

Two magnetic products interact from a significantly greater distance than a magnet and steel combination. The setup of magnet-to-magnet creates a more powerful interaction and a larger range of action. Designing a solid fastener? Apply two magnets instead of a neodymium and a striker plate. Remember that when bringing together two magnets, the collision energy is extreme. The repulsion force is slightly lower than the attraction, but still large.
*Flux density between like poles reaches ~0 Gs at the geometric center between the magnets (caused by magnetic field nullification).
* Figures refer to friction force of dual matching neodymium magnets (friction ~0.15 for Ni-Ni coating).

Table 7: Hazards (implants) - precautionary measures

Extremely neodym field is a serious hazard to electronics and pacemakers. These NdFeB products produce a flux that disrupts operation of digital equipment. Remember: the unseen radiation penetrates the body and housings. Increased vigilance must be exercised by people with cochlear implants and drug dispensers. Influence will be felt by: mechanical watches, car keys, speakers, and displays. Do not bring the product near payment cards, HDD media, or precise measuring instruments.

Table 8: Impact energy (kinetic energy) - collision effects

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	24.74 km/h (6.87 m/s)	0.31 J

50 mm	54.36 km/h (15.10 m/s)	1.49 J
100 mm	76.87 km/h (21.35 m/s)	2.98 J

Neodymium magnets are very brittle – a collision with steel can result in shattering. Pay attention to connection velocity – a magnet released freely becomes dangerous. Striking energy can destroy the magnet or injury to skin. Always hold the magnet during mounting so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Wear eye protection when playing with powerful specimens.

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

Water displaces steel, making heavy objects slightly lighter. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Shear force

*Note: On a vertical surface, the magnet holds just ~20% of its nominal pull.

2. Efficiency vs thickness

*Thin metal sheet (e.g. computer case) severely 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) = 0.71

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 presented product is an extremely powerful cylinder magnet, composed of durable NdFeB material, which, at dimensions of Ø14.9x10 mm, guarantees the highest energy density. This specific item boasts high dimensional repeatability and industrial build quality, making it a perfect solution for the most demanding engineers and designers. As a cylindrical magnet with impressive force (approx. 7.60 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring rapid order fulfillment. Moreover, its Ni-Cu-Ni coating secures it against corrosion in standard 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 pull force of 74.57 N with a weight of only 13.08 g, this rod 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., 14.9.1 mm) using two-component epoxy glues. To ensure stability in automation, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.

Magnets NdFeB grade N38 are suitable for 90% of applications in modeling and machine building, where extreme miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø14.9x10), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.

The presented product is a neodymium magnet with precisely defined parameters: diameter 14.9 mm and height 10 mm. The value of 74.57 N means that the magnet is capable of holding a weight many times exceeding its own mass of 13.08 g. 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 14.9 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.

Strengths as well as weaknesses of rare earth magnets.

Strengths

Apart from their notable power, neodymium magnets have these key benefits:

Their strength remains stable, and after around ten years it drops only by ~1% (theoretically),
They are resistant to demagnetization induced by presence of other magnetic fields,
The use of an metallic coating of noble metals (nickel, gold, silver) causes the element to have aesthetics,
They show high magnetic induction at the operating surface, making them more effective,
Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
Possibility of individual modeling as well as adapting to precise conditions,
Versatile presence in advanced technology sectors – they are utilized in mass storage devices, electric drive systems, precision medical tools, and other advanced devices.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which makes them useful in small systems

Limitations

Disadvantages of NdFeB magnets:

To avoid cracks under impact, we recommend using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
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 stability even at temperatures up to 230°C
Magnets exposed to a humid environment can rust. Therefore while using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
Due to limitations in producing threads and complicated shapes in magnets, we recommend using casing - magnetic mount.
Health risk to health – tiny shards of magnets are risky, if swallowed, which gains importance in the context of child health protection. Furthermore, small components of these magnets can complicate diagnosis medical in case of swallowing.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Lifting parameters

Highest magnetic holding force – what contributes to it?

The force parameter is a result of laboratory testing conducted under specific, ideal conditions:

with the application of a yoke made of special test steel, ensuring maximum field concentration
whose transverse dimension equals approx. 10 mm
with a plane cleaned and smooth
under conditions of ideal adhesion (surface-to-surface)
under vertical application of breakaway force (90-degree angle)
at conditions approx. 20°C

Magnet lifting force in use – key factors

In practice, the actual holding force results from several key aspects, ranked from most significant:

Clearance – existence of foreign body (paint, dirt, gap) acts as an insulator, which reduces capacity rapidly (even by 50% at 0.5 mm).
Force direction – catalog parameter refers to detachment vertically. When attempting to slide, the magnet holds much less (typically approx. 20-30% of maximum force).
Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
Steel type – low-carbon steel attracts best. Alloy admixtures decrease magnetic permeability and holding force.
Plate texture – ground elements guarantee perfect abutment, which increases force. Uneven metal weaken the grip.
Temperature influence – high temperature reduces pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.

Lifting capacity was assessed with the use of a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, in contrast under shearing force the load capacity is reduced by as much as 75%. In addition, even a minimal clearance between the magnet and the plate decreases the holding force.

Warnings

Dust is flammable

Dust produced during cutting of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.

Power loss in heat

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

Magnetic interference

A powerful magnetic field negatively affects the functioning of compasses in smartphones and navigation systems. Do not bring magnets near a device to prevent breaking the sensors.

Data carriers

Equipment safety: Neodymium magnets can ruin payment cards and sensitive devices (heart implants, hearing aids, timepieces).

Adults only

Strictly store magnets away from children. Choking hazard is significant, and the effects of magnets connecting inside the body are tragic.

Nickel coating and allergies

Certain individuals experience a contact allergy to nickel, which is the standard coating for neodymium magnets. Prolonged contact might lead to skin redness. We suggest wear protective gloves.

Magnet fragility

Despite the nickel coating, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.

Powerful field

Be careful. Neodymium magnets act from a long distance and snap with huge force, often faster than you can react.

Serious injuries

Large magnets can break fingers in a fraction of a second. Do not put your hand between two attracting surfaces.

Pacemakers

Warning for patients: Powerful magnets affect medical devices. Keep at least 30 cm distance or request help to work with the magnets.
