Pulling power decreases drastically per each millimeter of distance. Note that even a very thin break (e.g., dirt, paint, veneer) strongly diminishes the holding power. Magnetic products operate optimally during direct contact; distance nullifies the power. See how quickly the load capacity fall, when the magnet does not touch directly to the metal substrate. When planning the arrangement, avoid unnecessary gaps.

The following data presents the theoretical weight limit necessary to start the slippage of the magnet down along a upright metal surface (considering typical friction coefficient). This value depends on the distance between the magnet and the metal.

Table 3: Wall mounting (shearing) - vertical pull
MW 15x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.86 kg / 1.90 pounds 861.0 g / 8.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.57 kg / 1.27 pounds 574.0 g / 5.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.29 kg / 0.63 pounds 287.0 g / 2.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.44 kg / 3.16 pounds 1435.0 g / 14.1 N

When hanging a holder on a vertical wall (e.g., a board), it you can count on just about 20%-30% of nominal attraction strength. Gravitational force as well as a low friction coefficient cause that magnets move down easier than they pop off the substrate. Designing a hanger? Note that the sliding force is much weaker than the perpendicular breakaway force. On a slippery surface, the magnet will give way down under a significantly smaller cargo. Application of an anti-slip layer can drastically raise the stability.

12 mm	100%	2.87 kg / 6.33 pounds 2870.0 g / 28.2 N

A thin metal plate is incapable of conduct the full magnetic flux, which wastes potential of the holder. Should you mount a strong magnet to a weak sheet, the magnetism will pass right through and the pull force will drop sharply. To squeeze 100% of this magnet's power, you require a sufficiently solid element of steel. The saturation phenomenon causes that on thin elements (e.g., car bodies), the magnet works worse. We advise picking the steel thickness based on the following data.

Classic neodymiums change their properties strength above the temperature limit. Watch out for overheating – heat can permanently damage this product. With every degree above norm, the magnet's power briefly lowers. Avoid using this product close to ovens exceeding its working range. Exceeding the critical threshold will cause destruction of magnetic properties.

*Important note: Temperature resistance is determined by both grade, as well as the dimension ratios. Flat magnets (pancake types) are more susceptible to demagnetization under lower heat stress than taller cylinders. Red status in the table signals a risk of irreversible loss for this particular item.

Two strong neodymiums interact from a wider radius than a magnet and steel setup. The setup of magnet-to-magnet creates a more powerful interaction and a larger range of action. Planning to create a powerful holder? Use a pair of magnets instead of one magnet and a striker plate. Exercise caution that when bringing together two magnets, the pinch force is huge. The repulsion force is marginally weaker than the connection force, but still impressive.
*Field value between like poles reaches ~0 Gs in the exact middle of the gap (resulting from vector opposition).
Note: Results demonstrate sliding force of a pair of matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

Powerful magnet radiation is a large risk to IT equipment and medical implants. These magnets produce a flux that disrupts operation of digital equipment. Be aware: the invisible magnetic field acts through matter and housings. Special caution must be exercised by people with hearing aids and drug dispensers. The risk also applies to: mechanical watches, car keys, speakers, and displays. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

NdFeB products are prone to chipping – a strong collision with metal causes immediate chipping. Pay attention to connection velocity – a neodymium left loose speeds with massive force. Kinetic force can cause material chips or injury to skin. Always hold the magnet during bringing near metal so it doesn't hit with great force against the steel surface. A collision at high speed ends with a crack of the neodymium. Use safety goggles when playing with powerful specimens.

Contrary to myths, water does not block the magnetic field. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Vertical hold

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

2. Steel saturation

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

3. Power loss vs temp

*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) = 0.29

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 an exceptionally strong cylinder magnet, manufactured from advanced NdFeB material, which, with dimensions of Ø15x3 mm, guarantees maximum efficiency. This specific item is characterized by an accuracy of ±0.1mm and professional build quality, making it an excellent solution for the most demanding engineers and designers. As a cylindrical magnet with impressive force (approx. 2.87 kg), this product is in stock from our European logistics center, ensuring lightning-fast order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is perfect for building generators, advanced Hall effect sensors, and efficient magnetic separators, where field concentration on a small surface counts. Thanks to the pull force of 28.14 N with a weight of only 3.98 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 immediate cracking of this professional component. To ensure stability in automation, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.

Magnets NdFeB grade 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 even stronger magnets in the same volume (Ø15x3), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.

This model is characterized by dimensions Ø15x3 mm, which, at a weight of 3.98 g, makes it an element with impressive magnetic energy density. The value of 28.14 N means that the magnet is capable of holding a weight many times exceeding its own mass of 3.98 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 15 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 neodymium magnets.

Strengths

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

They retain magnetic properties for around 10 years – the loss is just ~1% (according to analyses),
They are resistant to demagnetization induced by presence of other magnetic fields,
Thanks to the reflective finish, the surface of Ni-Cu-Ni, gold-plated, or silver-plated gives an elegant appearance,
Magnets possess huge magnetic induction on the surface,
Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
Possibility of custom forming as well as adapting to defined conditions,
Significant place in advanced technology sectors – they serve a role in magnetic memories, electromotive mechanisms, precision medical tools, and industrial machines.
Thanks to their power density, small magnets offer high operating force, with minimal size,

Weaknesses

Cons of neodymium magnets: weaknesses and usage proposals

To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
Neodymium magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
We recommend a housing - magnetic mechanism, due to difficulties in creating threads inside the magnet and complicated forms.
Possible danger resulting from small fragments of magnets are risky, when accidentally swallowed, which becomes key in the context of child safety. Additionally, tiny parts of these products can disrupt the diagnostic process medical when they are in the body.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities

Pull force analysis

Maximum magnetic pulling force – what affects it?

The specified lifting capacity refers to the peak performance, measured under laboratory conditions, specifically:

with the application of a yoke made of low-carbon steel, ensuring full magnetic saturation
possessing a massiveness of at least 10 mm to ensure full flux closure
with a plane free of scratches
without the slightest air gap between the magnet and steel
under perpendicular force direction (90-degree angle)
at ambient temperature approx. 20 degrees Celsius

Lifting capacity in real conditions – factors

Real force impacted by working environment parameters, such as (from most important):

Gap between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
Direction of force – maximum parameter is available only during pulling at a 90° angle. The force required to slide of the magnet along the surface is usually several times lower (approx. 1/5 of the lifting capacity).
Steel thickness – too thin plate does not close the flux, causing part of the power to be wasted to the other side.
Metal type – different alloys reacts the same. High carbon content worsen the interaction with the magnet.
Base smoothness – the more even the surface, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
Temperature influence – hot environment reduces pulling force. Too high temperature can permanently damage the magnet.

Lifting capacity was assessed with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, however under parallel forces the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet and the plate reduces the lifting capacity.

Precautions when working with neodymium magnets

Conscious usage

Use magnets with awareness. Their huge power can shock even experienced users. Plan your moves and do not underestimate their force.

Fragile material

Protect your eyes. Magnets can explode upon violent connection, launching shards into the air. We recommend safety glasses.

Do not drill into magnets

Powder created during machining of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.

Heat sensitivity

Standard neodymium magnets (N-type) lose magnetization when the temperature goes above 80°C. The loss of strength is permanent.

No play value

These products are not suitable for play. Accidental ingestion of a few magnets may result in them connecting inside the digestive tract, which poses a direct threat to life and necessitates urgent medical intervention.

Electronic devices

Device Safety: Strong magnets can damage payment cards and sensitive devices (pacemakers, medical aids, timepieces).

Phone sensors

GPS units and smartphones are extremely susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can decalibrate the internal compass in your phone.

Warning for allergy sufferers

Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If redness happens, cease working with magnets and use protective gear.

Physical harm

Mind your fingers. Two large magnets will join immediately with a force of massive weight, crushing anything in their path. Exercise extreme caution!

ICD Warning

Individuals with a ICD must maintain an safe separation from magnets. The magnetic field can interfere with the operation of the life-saving device.
