Pulling power weakens sharply per each millimeter of spacing. Note that every additional insulation layer (e.g., dirt, paint, dust) significantly reduces the pull force. Neodymiums operate strongest at the point of direct contact; distance nullifies the power. Observe how flashily the parameters fall, when the product does not touch directly to the steel surface. When designing the arrangement, avoid redundant distances.

This section presents the approximate force sufficient to initiate the slippage of the magnet down along a vertical metal surface (considering standard friction). This value depends on the air gap between the magnet and the surface.

Table 3: Wall mounting (sliding) - vertical pull
MW 10x8 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	1.01 kg / 2.24 pounds 1014.0 g / 9.9 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.68 kg / 1.49 pounds 676.0 g / 6.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.34 kg / 0.75 pounds 338.0 g / 3.3 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.69 kg / 3.73 pounds 1690.0 g / 16.6 N

When mounting a magnet on a upright wall (e.g., a car body), it will maintain only approx. 20%-30% of its maximum pull force. Gravitational force and a low friction coefficient mean that holders move down faster than they detach. Want to create a vertical fastening? Consider that the shear force is noticeably lower than the maximum static pull force. On a smooth steel, the holder will slide down under a significantly smaller load. Application of an anti-slip coating can drastically increase the grip.

12 mm	100%	3.38 kg / 7.45 pounds 3380.0 g / 33.2 N

A thin metal plate cannot conduct the full magnetic flux, which wastes potential of the holder. Should you install a neodymium to a weak sheet, the magnetism will penetrate right through and the attraction force will be weaker. To achieve the maximum of this neodymium's power, you need a suitably thick piece of metal. The material oversaturation causes that on thin elements (e.g., car bodies), the magnet shows lower pull force. We recommend selecting the steel cross-section based on the following data.

Classic neodymiums change their properties strength past the thermal threshold. Avoid high temperatures – heat can irreversibly destroy this magnet. As the temperature rises, the magnet's power temporarily lowers. Avoid using this magnet close to heaters higher than its safe range. Ignoring the limit will result in destruction of magnetic properties.

*Technical advisory: Thermal stability is determined by both grade, and the Permeance Coefficient Pc. Flat magnets (low Pc) may lose charge permanently sooner than long magnets. Warning indicator in the table indicates permanent field degradation for this specific geometry.

Two magnetic products interact from a wider radius than a magnet and steel setup. The connection of two magnets creates a more powerful interaction and a wider radius of action. Designing a solid fastener? Apply two magnets instead of a neodymium and a striker plate. Be careful that when connecting a pair of magnets, the collision energy is massive. The levitation is marginally weaker than the connection force, but still large.
*Flux density for N-N configuration drops to ~0 Gs at the midpoint of the gap (caused by magnetic field nullification).
Attention: Figures refer to friction force of two identical neodymium magnets (friction ~0.15 for Ni-Ni plating).

A strong magnetic field poses a serious hazard to IT equipment and medical implants. These magnets generate a flux that destroys function of digital equipment. Remember: the invisible magnetic field acts through matter and housings. Increased vigilance must be exercised by people with cochlear implants and insulin pumps. Influence will be felt by: automatic timepieces, remotes, speakers, and screens. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

NdFeB products are delicate – a collision with steel risks their cracking. Pay attention to connection velocity – a magnet released freely speeds with massive force. Impact energy can destroy the magnet or dangerous crushing to skin. Always hold the magnet during bringing near metal so it doesn't slam with momentum against the metal. A collision at high speed almost guarantees destruction of the magnet. Wear safety glasses when working with powerful specimens.

Rust risk: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

Water displaces steel, making heavy objects slightly lighter. However, remember the water resistance when pulling the rope quickly.

1. Wall mount (shear)

*Caution: On a vertical surface, the magnet holds just ~20% of its perpendicular strength.

2. Steel saturation

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

3. Thermal stability

*For standard magnets, the safety limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.79

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 cylindrical magnet, produced from durable NdFeB material, which, with dimensions of Ø10x8 mm, guarantees maximum efficiency. This specific item is characterized by a tolerance of ±0.1mm and industrial build quality, making it an ideal solution for professional engineers and designers. As a magnetic rod with significant force (approx. 3.38 kg), this product is in stock from our warehouse in Poland, ensuring quick order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating effectively protects it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.

It successfully proves itself in modeling, advanced robotics, and broadly understood industry, serving as a positioning or actuating element. Thanks to the pull force of 33.16 N with a weight of only 4.71 g, this rod is indispensable in miniature devices and wherever every gram matters.

Due to the delicate structure of the ceramic sinter, you must not use force-fitting (so-called press-fit), as this risks chipping the coating of this precision component. To ensure long-term durability in automation, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.

Magnets N38 are suitable for the majority of applications in modeling and machine building, where excessive miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø10x8), 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 Ø10x8 mm, which, at a weight of 4.71 g, makes it an element with impressive magnetic energy density. The key parameter here is the lifting capacity amounting to approximately 3.38 kg (force ~33.16 N), which, with such defined 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 10 mm. 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 through the diameter if your project requires it.

Pros as well as cons of rare earth magnets.

Strengths

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

They have unchanged lifting capacity, and over nearly 10 years their performance decreases symbolically – ~1% (in testing),
Neodymium magnets are distinguished by extremely resistant to demagnetization caused by magnetic disturbances,
By covering with a shiny layer of silver, the element gains an proper look,
The surface of neodymium magnets generates a intense magnetic field – this is one of their assets,
Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
Thanks to freedom in forming and the ability to modify to individual projects,
Fundamental importance in future technologies – they serve a role in HDD drives, electric motors, precision medical tools, also complex engineering applications.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Disadvantages

Disadvantages of NdFeB magnets:

At very strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
Limited ability of making threads in the magnet and complex forms - recommended is a housing - mounting mechanism.
Possible danger resulting from small fragments of magnets are risky, if swallowed, which gains importance in the context of child safety. Additionally, small elements of these products are able to be problematic in diagnostics 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 increases costs of application in large quantities

Holding force characteristics

Maximum holding power of the magnet – what affects it?

Magnet power is the result of a measurement for the most favorable conditions, taking into account:

on a plate made of mild steel, perfectly concentrating the magnetic field
with a thickness minimum 10 mm
with a surface free of scratches
under conditions of gap-free contact (surface-to-surface)
for force acting at a right angle (in the magnet axis)
in stable room temperature

Lifting capacity in real conditions – factors

In practice, the real power is determined by a number of factors, listed from crucial:

Air gap (between the magnet and the plate), as even a microscopic clearance (e.g. 0.5 mm) can cause a reduction in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
Force direction – catalog parameter refers to pulling vertically. When slipping, the magnet holds much less (often approx. 20-30% of maximum force).
Metal thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
Metal type – not every steel reacts the same. High carbon content weaken the attraction effect.
Smoothness – ideal contact is obtained only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
Thermal environment – temperature increase results in weakening of induction. Check the thermal limit for a given model.

Lifting capacity testing was conducted on a smooth plate of suitable thickness, under perpendicular forces, in contrast under parallel forces the holding force is lower. In addition, even a slight gap between the magnet and the plate reduces the holding force.

Safe handling of neodymium magnets

Do not underestimate power

Handle magnets consciously. Their powerful strength can surprise even experienced users. Plan your moves and do not underestimate their force.

Warning for heart patients

Health Alert: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.

Beware of splinters

Beware of splinters. Magnets can explode upon violent connection, ejecting sharp fragments into the air. We recommend safety glasses.

Demagnetization risk

Monitor thermal conditions. Exposing the magnet to high heat will destroy its magnetic structure and pulling force.

Allergy Warning

Nickel alert: The Ni-Cu-Ni coating contains nickel. If an allergic reaction occurs, immediately stop working with magnets and use protective gear.

Impact on smartphones

Navigation devices and mobile phones are highly sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can permanently damage the sensors in your phone.

Bodily injuries

Big blocks can crush fingers instantly. Never put your hand between two attracting surfaces.

Dust explosion hazard

Powder generated during machining of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.

Safe distance

Intense magnetic fields can corrupt files on payment cards, hard drives, and storage devices. Maintain a gap of at least 10 cm.

This is not a toy

Neodymium magnets are not toys. Swallowing a few magnets can lead to them pinching intestinal walls, which poses a critical condition and requires immediate surgery.
