Grip strength decreases significantly per each millimeter of gap. Remember that even the smallest gap (e.g., dirt, paint, dust) significantly reduces the pull force. Magnets work strongest in perfect adhesion; air break drastically cuts the power. Notice how quickly the pull force fall, when the magnet does not adhere flatly to the steel surface. When calculating the arrangement, eliminate unnecessary gaps.

The following data indicates the theoretical weight limit sufficient to initiate the slippage of the magnet vertically along a vertical steel wall (considering typical friction coefficient). The holding force varies with the air gap between the magnet and the metal.

Table 3: Wall mounting (sliding) - vertical pull
MW 8x1.5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.22 kg / 0.49 pounds 222.0 g / 2.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.15 kg / 0.33 pounds 148.0 g / 1.5 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.07 kg / 0.16 pounds 74.0 g / 0.7 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.37 kg / 0.82 pounds 370.0 g / 3.6 N

When placing a element on a vertical plane (e.g., a car body), it will maintain just approx. 20%-30% of its nominal power. Gravitational force and a weak degree of grip mean that magnets move down faster than they pull off. Planning a vertical fastening? Remember that the shear force is noticeably lower than the maximum static pull force. On a smooth steel, the holder will give way down under a significantly smaller cargo. Application of an anti-slip pad can significantly increase the grip.

12 mm	100%	0.74 kg / 1.63 pounds 740.0 g / 7.3 N

A too thin steel is unable to focus the entire magnetic field, which weakens actual performance of the magnet. Should you attach a powerful product to a too thin substrate, the field will pass right through and the attraction force will be weaker. To squeeze the maximum of this magnet's power, you need a suitably thick piece of metal. The saturation effect causes that on thin elements (e.g., car bodies), the product shows lower pull force. We advise picking the steel thickness based on the following data.

Classic neodymiums change their properties strength past the thermal threshold. Protect against heat – heat can irreversibly demagnetize this magnet. With increasing heat, the neodymium's force temporarily drops. Avoid using this product in hot environments exceeding its working range. Exceeding the critical threshold will result in irreversible degradation of magnetic properties.

*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 sooner than taller cylinders. The danger warning in the table indicates permanent field degradation for this particular item.

Two magnets attract each other from a much further distance than a neodymium and metal setup. The setup of magnet-to-magnet creates a more powerful interaction and a wider radius of operation. Planning to create a strong closure? Utilize two neodymiums instead of one magnet and a striker plate. Be careful that when bringing together two magnets, the impact force is extreme. The levitation is a bit weaker than the connection force, but still significant.
*Flux density in repulsion mode reaches ~0 Gs at the midpoint of the gap (due to field cancellation).
Attention: Results apply to friction force of dual same neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

Extremely neodym field poses a real danger to electronics and medical implants. These neodymiums produce a flux that prevents correct functioning of digital equipment. Notice: the unseen radiation passes through tissues and housings. Exceptional care must be taken by people with cochlear implants and drug dispensers. The risk also applies to: automatic timepieces, remotes, membranes, and displays. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Magnetic elements are delicate – a violent impact against metal causes immediate chipping. Control the attraction moment – a magnet released freely becomes dangerous. Striking energy can cause material chips or injury to skin. Hold the magnet firmly during bringing near metal so it doesn't hit with great force against the steel surface. A collision at high speed means shattering of the neodymium. Wear safety glasses when handling with large magnets.

Rust risk: 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. Buoyancy helps in lifting finds.

1. Vertical hold

*Note: On a vertical wall, the magnet retains merely approx. 20-30% of its max power.

2. Steel thickness impact

*Thin metal sheet (e.g. 0.5mm PC case) drastically reduces 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) = 0.27

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.

The offered product is an incredibly powerful rod magnet, composed of durable NdFeB material, which, with dimensions of Ø8x1.5 mm, guarantees the highest energy density. This specific item is characterized by a tolerance of ±0.1mm and industrial build quality, making it an excellent solution for professional engineers and designers. As a magnetic rod with significant force (approx. 0.74 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring rapid order fulfillment. Furthermore, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is perfect for building generators, advanced Hall effect sensors, and efficient filters, where field concentration on a small surface counts. Thanks to the pull force of 7.27 N with a weight of only 0.57 g, this cylindrical magnet is indispensable in miniature devices and wherever low weight is crucial.

Since our magnets have a very precise dimensions, the best method is to glue them into holes with a slightly larger diameter (e.g., 8.1 mm) using two-component epoxy glues. To ensure long-term durability in automation, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.

Grade N38 is the most popular standard for professional neodymium magnets, offering an optimal price-to-power ratio and high resistance to demagnetization. If you need the strongest magnets in the same volume (Ø8x1.5), 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 Ø8x1.5 mm, which, at a weight of 0.57 g, makes it an element with high magnetic energy density. The value of 7.27 N means that the magnet is capable of holding a weight many times exceeding its own mass of 0.57 g. The product has a [NiCuNi] coating, which protects the surface against external factors, giving it an aesthetic, silvery shine.

This rod magnet is magnetized axially (along the height of 1.5 mm), which means that the N and S poles are located on the flat, circular surfaces. 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 diametrically if your project requires it.

Strengths as well as weaknesses of rare earth magnets.

Pros

In addition to their pulling strength, neodymium magnets provide the following advantages:

They do not lose power, even after approximately ten years – the reduction in strength is only ~1% (based on measurements),
They feature excellent resistance to magnetic field loss as a result of opposing magnetic fields,
Thanks to the smooth finish, the surface of Ni-Cu-Ni, gold-plated, or silver gives an modern appearance,
They are known for high magnetic induction at the operating surface, which affects their effectiveness,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
Possibility of precise shaping as well as modifying to specific requirements,
Fundamental importance in modern industrial fields – they find application in mass storage devices, drive modules, medical equipment, and complex engineering applications.
Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which allows their use in compact constructions

Disadvantages

Disadvantages of neodymium magnets:

To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution secures the magnet and simultaneously improves 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
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 as well as corrosion.
We suggest cover - magnetic mount, due to difficulties in producing threads inside the magnet and complex forms.
Health risk resulting from small fragments of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child health protection. Furthermore, tiny parts of these magnets can complicate diagnosis medical in case of swallowing.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities

Holding force characteristics

Highest magnetic holding force – what it depends on?

The force parameter is a result of laboratory testing executed under specific, ideal conditions:

on a base made of structural steel, optimally conducting the magnetic field
with a thickness minimum 10 mm
characterized by lack of roughness
with zero gap (without coatings)
during detachment in a direction vertical to the mounting surface
in temp. approx. 20°C

Lifting capacity in practice – influencing factors

In real-world applications, the real power depends on a number of factors, presented from crucial:

Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
Loading method – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
Plate thickness – insufficiently thick steel causes magnetic saturation, causing part of the flux to be lost into the air.
Plate material – low-carbon steel gives the best results. Alloy steels decrease magnetic properties and lifting capacity.
Surface structure – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Roughness creates an air distance.
Temperature – temperature increase causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, however under parallel forces the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate reduces the lifting capacity.

Safety rules for work with neodymium magnets

Medical interference

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

Physical harm

Danger of trauma: The attraction force is so immense that it can cause blood blisters, crushing, and even bone fractures. Protective gloves are recommended.

Allergy Warning

Certain individuals experience a contact allergy to nickel, which is the typical protective layer for NdFeB magnets. Prolonged contact can result in an allergic reaction. We suggest use protective gloves.

GPS and phone interference

Navigation devices and smartphones are highly sensitive to magnetic fields. Direct contact with a strong magnet can ruin the sensors in your phone.

Powerful field

Be careful. Neodymium magnets attract from a distance and snap with huge force, often faster than you can move away.

Fire risk

Powder produced during grinding of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.

Beware of splinters

Despite metallic appearance, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.

No play value

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

Keep away from computers

Avoid bringing magnets near a wallet, laptop, or TV. The magnetism can permanently damage these devices and erase data from cards.

Operating temperature

Avoid heat. Neodymium magnets are sensitive to heat. If you require operation above 80°C, ask us about special high-temperature series (H, SH, UH).
