Pulling power drops sharply per each millimeter of gap. Keep in mind that even the smallest gap (e.g., contamination, varnish, veneer) noticeably weakens the grip. Neodymiums work optimally at the point of direct contact; gap drastically cuts the force. Observe how flashily the load capacity drop, when the product does not adhere directly to the metal substrate. When designing the mounting, avoid redundant distances.

The following data indicates the theoretical weight limit needed to initiate the shifting of the magnet vertically along a vertical steel plate (considering typical friction coefficient). This parameter is a function of the gap size between the magnet and the surface.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces
MW 15x4 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	1.27 kg / 2.79 lbs 1266.0 g / 12.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.84 kg / 1.86 lbs 844.0 g / 8.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.42 kg / 0.93 lbs 422.0 g / 4.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	2.11 kg / 4.65 lbs 2110.0 g / 20.7 N

When hanging a element on a upright wall (e.g., a car body), it you can count on only approx. 1/5 of nominal attraction strength. Gravitational force and a low friction coefficient influence the fact that products slip easier than they pull off. Planning a wall mount? Consider that the shear force is noticeably lower than the maximum static pull force. On a smooth steel, the element will slide down under a noticeably lighter load. Utilizing a rubberized pad can significantly increase the grip.

A thin sheet is not enough to focus the full magnetic flux, which squanders power of the holder. If you attach a powerful product to a too thin substrate, the field will pass right through and the pull force will drop sharply. To achieve the maximum of this neodymium's power, you need a suitably thick element of metal. The saturation effect causes that on sheet metal structures (e.g., car bodies), the product holds weaker. We advise picking the steel thickness according to the table below.

Standard neodymium magnets change their properties parameters above the temperature limit. Avoid high temperatures – heat can irreversibly damage this product. As the temperature rises, the neodymium's capacity temporarily decreases. Refrain from using this product close to heaters exceeding its safe range. Too high temperature will lead to destruction of magnetism.

*Important note: Heat tolerance depends not only on the material grade, as well as the dimension ratios. Thin magnets (low permeance coefficient) risk losing magnetic properties at lower temperatures than taller cylinders. Warning indicator in the table signals a risk of irreversible loss for this specific geometry.

Two magnetic products interact from a wider radius than a magnet and steel combination. Such a system of two magnets generates a stronger field 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 impact force is extreme. The levitation is slightly lower than the attraction, but still impressive.
*Flux density between like poles drops to ~0 Gs at the midpoint of the gap (caused by magnetic field nullification).
Important: Estimates apply to shear force of two identical neodymium magnets (friction ~0.15 for Ni-Ni layer).

Powerful magnet radiation is a real danger to IT equipment as well as pacemakers. These NdFeB products produce a flux that destroys function of sensitive medical devices. Notice: the invisible magnetic field acts through matter and plastic. Special caution must be exercised by people with hearing aids and drug dispensers. Influence will be felt by: automatic timepieces, car keys, membranes, and screens. Do not place the magnet near cards, HDD media, or precise measuring instruments.

Table 8: Impact energy (cracking risk) - collision effects
MW 15x4 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	28.99 km/h (8.05 m/s)	0.17 J
30 mm	49.30 km/h (13.69 m/s)	0.50 J
50 mm	63.63 km/h (17.68 m/s)	0.83 J
100 mm	89.99 km/h (25.00 m/s)	1.66 J

Neodymium magnets are very brittle – a collision with steel risks their cracking. Watch the impact speed – a magnet released freely turns into a projectile. Striking energy can destroy the magnet or painful pinches to skin. Always hold the magnet during installation so it doesn't hit with great force against the steel surface. A collision at high speed almost guarantees destruction of the neodymium. Wear eye protection when playing with large magnets.

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

The magnetic field penetrates through water without any losses. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Shear force

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

2. Steel saturation

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

3. Power loss vs temp

*For standard magnets, 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) = 0.37

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 presented product is an incredibly powerful rod magnet, manufactured from modern NdFeB material, which, at dimensions of Ø15x4 mm, guarantees the highest energy density. The MW 15x4 / N38 component features 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. 4.22 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring rapid order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

It finds application in modeling, advanced robotics, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 41.38 N with a weight of only 5.3 g, this rod is indispensable in miniature devices and wherever every gram matters.

Due to the delicate structure of the ceramic sinter, we absolutely advise against 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 high repeatability of the connection.

Magnets NdFeB grade N38 are suitable for the majority of applications in automation and machine building, where excessive miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø15x4), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.

This model is characterized by dimensions Ø15x4 mm, which, at a weight of 5.3 g, makes it an element with high magnetic energy density. The key parameter here is the holding force amounting to approximately 4.22 kg (force ~41.38 N), which, with such compact dimensions, proves the high grade 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 15 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 through the diameter if your project requires it.

Strengths and weaknesses of rare earth magnets.

Strengths

Apart from their strong holding force, neodymium magnets have these key benefits:

They have stable power, and over nearly 10 years their attraction force decreases symbolically – ~1% (in testing),
Magnets effectively protect themselves against loss of magnetization caused by foreign field sources,
By applying a lustrous layer of nickel, the element presents an professional look,
Magnetic induction on the working part of the magnet turns out to be maximum,
Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling operation at temperatures reaching 230°C and above...
Possibility of accurate shaping as well as adjusting to specific needs,
Huge importance in innovative solutions – they are utilized in mass storage devices, drive modules, advanced medical instruments, and multitasking production systems.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which enables their usage in compact constructions

Cons

Problematic aspects of neodymium magnets: weaknesses and usage proposals

At very strong impacts they can crack, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
Neodymium magnets decrease their strength 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
They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
We suggest casing - magnetic mount, due to difficulties in creating nuts inside the magnet and complicated shapes.
Potential hazard resulting from small fragments of magnets are risky, when accidentally swallowed, which is particularly important in the context of child health protection. It is also worth noting that small components of these products are able to disrupt the diagnostic process medical in case of swallowing.
Due to expensive raw materials, their price exceeds standard values,

Pull force analysis

Magnetic strength at its maximum – what affects it?

The lifting capacity listed is a theoretical maximum value performed under the following configuration:

on a plate made of mild steel, optimally conducting the magnetic flux
whose thickness equals approx. 10 mm
with an ideally smooth touching surface
without the slightest insulating layer between the magnet and steel
for force acting at a right angle (in the magnet axis)
at conditions approx. 20°C

Practical lifting capacity: influencing factors

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

Distance – existence of foreign body (rust, tape, gap) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
Metal type – not every steel reacts the same. Alloy additives worsen the attraction effect.
Smoothness – ideal contact is obtained only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
Operating temperature – neodymium magnets have a sensitivity to temperature. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).

Lifting capacity was measured by applying a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Moreover, even a slight gap between the magnet’s surface and the plate lowers the load capacity.

Safety rules for work with NdFeB magnets

Conscious usage

Before use, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Think ahead.

Metal Allergy

A percentage of the population have a hypersensitivity to nickel, which is the common plating for NdFeB magnets. Frequent touching may cause dermatitis. We recommend wear protective gloves.

Bodily injuries

Risk of injury: The attraction force is so great that it can cause blood blisters, pinching, and broken bones. Protective gloves are recommended.

Maximum temperature

Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and strength.

Pacemakers

Warning for patients: Powerful magnets affect medical devices. Keep at least 30 cm distance or ask another person to handle the magnets.

Magnetic media

Do not bring magnets close to a purse, laptop, or TV. The magnetism can destroy these devices and wipe information from cards.

Shattering risk

Beware of splinters. Magnets can fracture upon uncontrolled impact, launching shards into the air. We recommend safety glasses.

GPS Danger

Navigation devices and smartphones are extremely susceptible to magnetism. Close proximity with a powerful NdFeB magnet can decalibrate the sensors in your phone.

Danger to the youngest

Always keep magnets out of reach of children. Ingestion danger is high, and the consequences of magnets connecting inside the body are very dangerous.

Mechanical processing

Fire hazard: Neodymium dust is highly flammable. Do not process magnets in home conditions as this may cause fire.
