Magnetic force weakens sharply with every subsequent millimeter of gap. Keep in mind that every additional insulation layer (e.g., contamination, varnish, dust) significantly reduces the pull force. Magnets operate strongest during direct contact; distance weakens the force. See how rapidly the parameters plummet, when the product does not adhere flatly to the steel surface. When designing the mounting, discard additional spacers.

The table below shows the approximate shear load needed to initiate the slippage of the magnet downwards along a upright metal surface (assuming standard friction). This parameter depends on the separation distance between the magnet and the metal.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MW 18x10 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg)
Raw steel	µ = 0.3 30% Nominalnej Siły	3.23 kg / 3228.0 g 31.7 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	2.15 kg / 2152.0 g 21.1 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	1.08 kg / 1076.0 g 10.6 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	5.38 kg / 5380.0 g 52.8 N

When mounting a holder on a upright wall (e.g., a fridge), it will maintain barely about 1/5 of its nominal power. Gravitational force as well as a low friction coefficient influence the fact that products slip easier than they pull off. Want to create a hanger? Note that the shear force is noticeably lower than the maximum static pull force. On a smooth steel, the holder will slip down under a significantly smaller weight. Application of an anti-slip coating can significantly increase the grip.

Table 4: Material efficiency (saturation) - sheet metal selection

Steel thickness (mm)	% power	Real pull force (kg)
0.5 mm	5%	0.54 kg / 538.0 g 5.3 N

10 mm	100%	10.76 kg / 10760.0 g 105.6 N

A thin metal plate is incapable of conduct the entire magnetic field, which wastes potential of the magnet. Should you attach a powerful product to a thin surface, the flux will pass right through and the holding will be smaller. To squeeze the maximum of this magnet's power, you require a sufficiently solid element of metal. The saturation effect causes that on sheet metal structures (e.g., thin profiles), the product shows lower pull force. We advise picking the steel cross-section according to the table below.

Standard neodymium magnets change their properties parameters after exceeding the maximum temperature. Avoid high temperatures – high temperature can permanently demagnetize this magnet. With every degree above norm, the magnet's force temporarily lowers. Avoid using this magnet in hot environments higher than its working range. Ignoring the limit will result in destruction of magnetism.

*Engineering note: Thermal stability is determined by both grade, but also on the magnet's shape. Thin magnets (pancake types) risk losing magnetic properties at lower temperatures compared to rod magnets. The danger warning in the table signals permanent field degradation for this specific geometry.

Two strong neodymiums interact from a significantly greater distance than a magnet and steel setup. The connection of magnet-to-magnet creates a more powerful interaction and a larger range of performance. Designing a strong closure? Apply two magnets instead of one magnet and a striker plate. Be careful that when bringing together two magnets, the collision energy is extreme. The levitation is marginally weaker than the connection force, but still significant.
*Flux density between like poles drops to ~0 Gs at the geometric center between the magnets (due to field cancellation).

Extremely neodym field is a large risk to IT equipment as well as medical implants. These NdFeB products produce a field that destroys function of sensitive medical devices. Notice: the invisible magnetic field acts through matter and plastic. Special caution must be taken by people with hearing aids and drug dispensers. Influence will be felt by: automatic timepieces, car keys, speakers, and screens. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Table 8: Collisions (cracking risk) - warning
MW 18x10 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	24.70 km/h (6.86 m/s)	0.45 J
30 mm	41.49 km/h (11.52 m/s)	1.27 J
50 mm	53.54 km/h (14.87 m/s)	2.11 J
100 mm	75.72 km/h (21.03 m/s)	4.22 J

NdFeB products are prone to chipping – a violent impact against metal risks their cracking. Watch the impact speed – a magnet released freely speeds with massive force. Impact energy can cause material chips or dangerous crushing to fingers. Hold the magnet firmly during bringing near metal 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 magnet. Wear safety glasses when working with powerful specimens.

Corrosion warning: 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. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Sliding resistance

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

2. Plate thickness effect

*Thin metal sheet (e.g. 0.5mm PC case) significantly limits the holding force.

3. Power loss vs temp

*For N38 grade, the safety limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.63

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.

This product is a very strong cylindrical magnet, composed of modern NdFeB material, which, at dimensions of Ø18x10 mm, guarantees optimal power. This specific item boasts an accuracy of ±0.1mm and professional build quality, making it an ideal solution for the most demanding engineers and designers. As a magnetic rod with significant force (approx. 10.76 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring lightning-fast order fulfillment. Furthermore, its Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

It finds application in modeling, advanced automation, and broadly understood industry, serving as a fastening or actuating element. Thanks to the high power of 105.51 N with a weight of only 19.09 g, this rod is indispensable in electronics and wherever low weight is crucial.

Since our magnets have a tolerance of ±0.1mm, the best method is to glue them into holes with a slightly larger diameter (e.g., 18.1 mm) using two-component epoxy glues. To ensure long-term durability 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 the strongest magnets in the same volume (Ø18x10), 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 Ø18x10 mm, which, at a weight of 19.09 g, makes it an element with high magnetic energy density. The key parameter here is the lifting capacity amounting to approximately 10.76 kg (force ~105.51 N), which, with such compact dimensions, proves the high power 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 18 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.

Strengths and weaknesses of neodymium magnets.

Strengths

Besides their remarkable field intensity, neodymium magnets offer the following advantages:

They have constant strength, and over nearly 10 years their performance decreases symbolically – ~1% (according to theory),
They possess excellent resistance to magnetic field loss due to external fields,
A magnet with a metallic silver surface is more attractive,
They are known for 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 accurate modeling and optimizing to precise needs,
Key role in future technologies – they are used in computer drives, electromotive mechanisms, medical equipment, also multitasking production systems.
Thanks to their power density, small magnets offer high operating force, in miniature format,

Disadvantages

Disadvantages of neodymium magnets:

Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a steel housing, which not only protects them against impacts but also raises their durability
Neodymium magnets lose their power 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
Magnets exposed to a humid environment can rust. Therefore during using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
Limited possibility of making nuts in the magnet and complicated forms - recommended is casing - magnet mounting.
Possible danger related to microscopic parts of magnets are risky, in case of ingestion, which becomes key in the context of child health protection. It is also worth noting that small elements of these devices can be problematic in diagnostics medical after entering the body.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Lifting parameters

Highest magnetic holding force – what affects it?

Breakaway force is the result of a measurement for the most favorable conditions, including:

using a sheet made of high-permeability steel, functioning as a magnetic yoke
whose thickness equals approx. 10 mm
characterized by lack of roughness
under conditions of gap-free contact (surface-to-surface)
under axial force direction (90-degree angle)
in stable room temperature

Key elements affecting lifting force

Bear in mind that the application force may be lower subject to elements below, in order of importance:

Gap (between the magnet and the plate), as even a tiny clearance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
Loading method – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of generating force.
Plate material – mild steel attracts best. Higher carbon content decrease magnetic permeability and lifting capacity.
Surface finish – ideal contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
Temperature influence – hot environment weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.

Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under parallel forces the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate lowers the lifting capacity.

Safe handling of neodymium magnets

Cards and drives

Equipment safety: Strong magnets can damage payment cards and sensitive devices (heart implants, medical aids, mechanical watches).

Powerful field

Exercise caution. Neodymium magnets attract from a distance and snap with huge force, often faster than you can react.

Impact on smartphones

An intense magnetic field disrupts the operation of magnetometers in phones and navigation systems. Maintain magnets close to a smartphone to avoid damaging the sensors.

Power loss in heat

Watch the temperature. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and pulling force.

Crushing risk

Pinching hazard: The pulling power is so immense that it can cause blood blisters, crushing, and broken bones. Use thick gloves.

Risk of cracking

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

Metal Allergy

A percentage of the population suffer from a contact allergy to Ni, which is the typical protective layer for NdFeB magnets. Prolonged contact might lead to an allergic reaction. We strongly advise use safety gloves.

Fire warning

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

Medical implants

Patients with a pacemaker have to maintain an large gap from magnets. The magnetic field can disrupt the functioning of the implant.

Choking Hazard

Adult use only. Tiny parts can be swallowed, causing severe trauma. Keep out of reach of kids and pets.
