Magnetic force drops significantly with every subsequent millimeter of spacing. Keep in mind that every additional insulation layer (e.g., contamination, varnish, veneer) noticeably reduces the pull force. Neodymiums work strongest at the point of direct contact; air break weakens the power. Observe how quickly the parameters fall, when the product does not touch tightly to the steel surface. When calculating the assembly, avoid redundant distances.

The table below shows the theoretical force needed to cause the downward movement of the magnet vertically along a vertical metal surface (assuming typical friction coefficient). The holding force is relative to the air gap between the magnet and the metal.

Table 3: Vertical assembly (sliding) - vertical pull
MW 14x10 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg)
Raw steel	µ = 0.3 30% Nominalnej Siły	2.01 kg / 2013.0 g 19.7 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.34 kg / 1342.0 g 13.2 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.67 kg / 671.0 g 6.6 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	3.36 kg / 3355.0 g 32.9 N

When hanging a element on a vertical plane (e.g., a board), it you can count on barely about 1/5 of nominal attraction strength. Gravity and a weak degree of grip cause that holders slip faster than they pull off. Designing a hanger? Remember that the shear force is noticeably lower than the maximum static pull force. On a slippery surface, the element will give way down under a noticeably lighter weight. Utilizing a rubberized pad can significantly increase the grip.

Table 4: Material efficiency (saturation) - sheet metal selection
MW 14x10 / N38

Steel thickness (mm)	% power	Real pull force (kg)
0.5 mm	10%	0.67 kg / 671.0 g 6.6 N
1 mm	25%	1.68 kg / 1677.5 g 16.5 N
2 mm	50%	3.36 kg / 3355.0 g 32.9 N
5 mm	100%	6.71 kg / 6710.0 g 65.8 N
10 mm	100%	6.71 kg / 6710.0 g 65.8 N

A thin sheet cannot focus the full magnetic flux, which weakens actual performance of the magnet. Should you install a neodymium to a too thin substrate, the magnetism will pass right through and the holding will be smaller. To squeeze 100% of this magnet's potential, you need a suitably thick element of steel. The material oversaturation causes that on delicate walls (e.g., car bodies), the holder holds weaker. We advise picking the steel thickness based on the following data.

Classic neodymiums change their properties parameters past the thermal threshold. Protect against heat – high temperature can permanently damage this magnet. With increasing heat, the magnet's capacity briefly drops. Refrain from using this product close to heaters higher than its safe range. Too high temperature will cause irreversible degradation of magnetism.

*Technical advisory: Heat tolerance is determined by both grade, and the Permeance Coefficient Pc. Thin magnets (low Pc) are more susceptible to demagnetization at lower temperatures than taller cylinders. Warning indicator in the table indicates permanent field degradation for this particular item.

Two strong neodymiums attract each other from a wider radius than a magnet and steel setup. Such a system of two magnets generates a stronger field and a wider radius of action. Want to build a strong closure? Use a pair of magnets instead of a neodymium and a steel. Exercise caution that when attracting two neodymiums, the collision energy is extreme. The levitation is a bit weaker than the connection force, but still large.
*The magnetic induction for N-N configuration reaches ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).

Powerful magnet radiation is a real danger to electronics as well as medical implants. These neodymiums generate a flux that prevents correct functioning of sensitive medical devices. Be aware: the invisible magnetic field acts through matter and housings. Exceptional care must be taken by people with hearing aids and insulin pumps. Influence will be felt by: automatic timepieces, car keys, membranes, and screens. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

Magnetic elements are delicate – a strong collision with metal can result in shattering. Pay attention to connection velocity – a magnet released freely becomes dangerous. Impact energy can cause material chips or injury to skin. Always hold the magnet during installation so it doesn't slam with momentum against the steel surface. A collision at high speed means shattering of the neodymium. Wear eye protection when playing with powerful specimens.

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

1. Wall mount (shear)

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

2. Steel thickness impact

*Thin steel (e.g. computer case) significantly limits the holding force.

3. Thermal stability

*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) = 0.74

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 cylindrical magnet, produced from advanced NdFeB material, which, with dimensions of Ø14x10 mm, guarantees optimal power. The MW 14x10 / N38 component is characterized by high dimensional repeatability and professional build quality, making it an excellent solution for the most demanding engineers and designers. As a magnetic rod with significant force (approx. 6.71 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring quick order fulfillment. Additionally, its 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 automation, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 65.83 N with a weight of only 11.55 g, this rod is indispensable in electronics and wherever every gram matters.

Since our magnets have a very precise dimensions, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 14.1 mm) using two-component epoxy glues. To ensure long-term durability in industry, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.

Magnets N38 are strong enough for 90% of applications in automation and machine building, where extreme miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø14x10), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

The presented product is a neodymium magnet with precisely defined parameters: diameter 14 mm and height 10 mm. The key parameter here is the lifting capacity amounting to approximately 6.71 kg (force ~65.83 N), which, with such defined dimensions, proves the high power of the NdFeB material. The product has a [NiCuNi] coating, which secures it against external factors, giving it an aesthetic, silvery shine.

This cylinder is magnetized axially (along the height of 10 mm), which means that the N and S poles are located on the flat, circular surfaces. Such an arrangement is most desirable 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.

Pros as well as cons of Nd₂Fe₁₄B magnets.

Strengths

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

They have stable power, and over around 10 years their attraction force decreases symbolically – ~1% (in testing),
Magnets effectively defend themselves against demagnetization caused by external fields,
In other words, due to the smooth layer of nickel, the element is aesthetically pleasing,
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 forming and the capacity to modify to specific needs,
Huge importance in high-tech industry – they are used in magnetic memories, electromotive mechanisms, advanced medical instruments, also complex engineering applications.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which enables their usage in miniature devices

Disadvantages

Drawbacks and weaknesses of neodymium magnets: tips and applications.

To avoid cracks under impact, we recommend using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
Limited ability of making threads in the magnet and complex shapes - preferred is casing - magnetic holder.
Possible danger resulting from small fragments of magnets can be dangerous, if swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that small components of these devices can complicate diagnosis medical when they are in the body.
Due to expensive raw materials, their price is relatively high,

Lifting parameters

Magnetic strength at its maximum – what it depends on?

The load parameter shown represents the peak performance, recorded under optimal environment, specifically:

on a block made of mild steel, effectively closing the magnetic field
possessing a massiveness of at least 10 mm to ensure full flux closure
with an ground contact surface
with total lack of distance (without coatings)
during detachment in a direction perpendicular to the plane
at ambient temperature room level

Impact of factors on magnetic holding capacity in practice

Holding efficiency is influenced by specific conditions, mainly (from priority):

Distance – existence of any layer (paint, tape, gap) acts as an insulator, which reduces capacity rapidly (even by 50% at 0.5 mm).
Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
Plate thickness – too thin steel does not close the flux, causing part of the flux to be wasted to the other side.
Material composition – not every steel reacts the same. Alloy additives worsen the interaction with the magnet.
Surface structure – the more even the plate, the larger the contact zone and higher the lifting capacity. Roughness creates an air distance.
Operating temperature – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).

Lifting capacity testing was performed on a smooth plate of suitable thickness, under perpendicular forces, in contrast under shearing force the load capacity is reduced by as much as fivefold. Moreover, even a minimal clearance between the magnet and the plate reduces the holding force.

Safety rules for work with neodymium magnets

Beware of splinters

Despite metallic appearance, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.

This is not a toy

Always store magnets out of reach of children. Risk of swallowing is significant, and the consequences of magnets clamping inside the body are life-threatening.

Impact on smartphones

Navigation devices and smartphones are highly sensitive to magnetic fields. Close proximity with a strong magnet can permanently damage the sensors in your phone.

Handling guide

Handle with care. Rare earth magnets attract from a long distance and connect with massive power, often faster than you can react.

Fire risk

Combustion risk: Neodymium dust is explosive. Avoid machining magnets in home conditions as this risks ignition.

Serious injuries

Big blocks can smash fingers instantly. Do not put your hand between two attracting surfaces.

Power loss in heat

Avoid heat. NdFeB magnets are susceptible to heat. If you need operation above 80°C, look for special high-temperature series (H, SH, UH).

Electronic devices

Very strong magnetic fields can destroy records on credit cards, hard drives, and storage devices. Stay away of at least 10 cm.

Nickel allergy

Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If redness appears, immediately stop working with magnets and wear gloves.

Medical interference

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