Pulling power drops sharply with every subsequent millimeter of distance. Remember that every additional insulation layer (e.g., dirt, varnish, veneer) significantly diminishes the holding power. Magnetic products hold most effectively during direct contact; gap kills the force. See how flashily the load capacity fall, when the product does not adhere flatly to the steel surface. When designing the assembly, discard additional spacers.

The following data indicates the theoretical force required to start the sliding of the magnet vertically on a upright metal surface (considering standard friction). The holding force varies with the gap size between the magnet and the metal.

Table 3: Wall mounting (shearing) - vertical pull
MW 8x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.51 kg / 1.12 lbs 510.0 g / 5.0 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.34 kg / 0.75 lbs 340.0 g / 3.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.17 kg / 0.37 lbs 170.0 g / 1.7 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.85 kg / 1.87 lbs 850.0 g / 8.3 N

When hanging a element on a vertical surface (e.g., a board), it you can count on only about 20%-30% of its maximum pull force. Gravitational force as well as a low friction coefficient cause that products move down faster than they detach. Planning a hanger? Consider that the sliding force is significantly lower than the perpendicular breakaway force. On a smooth steel, the magnet will slide down under a noticeably lighter load. Using a rubber coating can effectively raise the stability.

A too thin steel is incapable of take in the entire magnetic field, which weakens actual performance of the magnet. If you attach a powerful product to a too thin substrate, the flux will penetrate right through and the attraction force will be weaker. To utilize the maximum of this neodymium's potential, you require a sufficiently solid backing of steel. The saturation effect causes that on thin elements (e.g., car bodies), the product holds weaker. We advise picking the steel dimension based on the following data.

Classic neodymiums change their properties strength after exceeding the maximum temperature. Watch out for overheating – excessive heat can irreversibly damage this magnet. As the temperature rises, the neodymium's capacity temporarily lowers. Do not use this product near heat sources higher than its safe range. Ignoring the limit will cause permanent loss of magnetism.

*Engineering note: Temperature resistance is determined by both grade, but also on the magnet's shape. Thin magnets (pancake types) may lose charge permanently sooner than long magnets. Warning indicator in the table indicates a risk of irreversible loss for this specific geometry.

Two magnetic products interact from a wider radius than a neodymium and metal setup. Such a system of magnet-to-magnet produces a massive flux and a further horizon of performance. Designing a solid fastener? Apply two magnets instead of a neodymium and a steel. Exercise caution that when connecting a pair of magnets, the impact force is huge. The repulsion force is slightly lower than the attraction, but still large.
*Flux density between like poles reaches ~0 Gs at the geometric center of the gap (caused by magnetic field nullification).
Note: Calculations refer to shear force of two matching magnets (friction ~0.15 for Ni-Ni plating).

Powerful magnet radiation is a real danger to IT equipment as well as pacemakers. These neodymiums produce a field that prevents correct functioning of sensitive medical devices. Notice: the unseen radiation passes through tissues and plastic. Exceptional care must be exercised by people with cochlear implants and drug dispensers. The risk also applies to: mechanical watches, remotes, membranes, and screens. Do not bring the product near payment cards, hard drives, or sensitive navigation tools.

NdFeB products are delicate – a violent impact against metal risks their cracking. Pay attention to connection velocity – a magnet released freely becomes dangerous. Kinetic force can destroy the magnet or injury to skin. Hold the magnet firmly during mounting so it doesn't slam with momentum against the steel surface. A collision at high speed ends with a crack of the magnet. Wear safety glasses when handling with powerful specimens.

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

Contrary to myths, water does not block the magnetic field. Buoyancy helps in lifting finds.

1. Sliding resistance

*Warning: On a vertical wall, the magnet retains just approx. 20-30% of its nominal pull.

2. Steel saturation

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

3. Power loss vs temp

*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) = 0.48

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 a very strong rod magnet, composed of modern NdFeB material, which, at dimensions of Ø8x3 mm, guarantees optimal power. This specific item is characterized by high dimensional repeatability and industrial build quality, making it a perfect solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 1.70 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring lightning-fast order fulfillment. Furthermore, its Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

This model is created for building generators, advanced Hall effect sensors, and efficient magnetic separators, where field concentration on a small surface counts. Thanks to the high power of 16.67 N with a weight of only 1.13 g, this rod is indispensable in electronics and wherever low weight is crucial.

Since our magnets have a tolerance of ±0.1mm, the best method is to glue them into holes with a slightly larger diameter (e.g., 8.1 mm) using epoxy glues. To ensure stability in automation, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.

Magnets N38 are strong enough for the majority of applications in automation and machine building, where extreme miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø8x3), 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 Ø8x3 mm, which, at a weight of 1.13 g, makes it an element with high magnetic energy density. The key parameter here is the lifting capacity amounting to approximately 1.70 kg (force ~16.67 N), which, with such defined dimensions, proves the high grade of the NdFeB material. The product has a [NiCuNi] coating, which secures it against oxidation, giving it an aesthetic, silvery shine.

This rod magnet is magnetized axially (along the height of 3 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 through the diameter if your project requires it.

Strengths as well as weaknesses of Nd₂Fe₁₄B magnets.

Strengths

Besides their magnetic performance, neodymium magnets are valued for these benefits:

They retain full power for around 10 years – the loss is just ~1% (based on simulations),
Neodymium magnets are characterized by extremely resistant to loss of magnetic properties caused by magnetic disturbances,
A magnet with a metallic nickel surface is more attractive,
Neodymium magnets achieve maximum magnetic induction on a small area, which allows for strong attraction,
Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures approaching 230°C and above...
Due to the potential of accurate molding and customization to specialized projects, magnetic components can be manufactured in a wide range of shapes and sizes, which amplifies use scope,
Significant place in innovative solutions – they are commonly used in HDD drives, electric drive systems, diagnostic systems, also technologically advanced constructions.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Limitations

What to avoid - cons of neodymium magnets and proposals for their use:

They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only shields the magnet but also improves its resistance to damage
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 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 those in rubber or plastics, which secure oxidation as well as corrosion.
Limited possibility of producing nuts in the magnet and complicated shapes - recommended is cover - mounting mechanism.
Possible danger to health – tiny shards of magnets pose a threat, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, tiny parts of these magnets are able to be problematic in diagnostics medical after entering the body.
With budget limitations the cost of neodymium magnets can be a barrier,

Holding force characteristics

Maximum magnetic pulling force – what contributes to it?

Information about lifting capacity was defined for the most favorable conditions, assuming:

using a base made of high-permeability steel, functioning as a circuit closing element
with a thickness minimum 10 mm
with an ground touching surface
with zero gap (without coatings)
during detachment in a direction vertical to the plane
in stable room temperature

Impact of factors on magnetic holding capacity in practice

In practice, the actual holding force depends on many variables, presented from most significant:

Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
Angle of force application – maximum parameter is reached only during perpendicular pulling. The resistance to sliding of the magnet along the plate is standardly several times lower (approx. 1/5 of the lifting capacity).
Plate thickness – too thin sheet causes magnetic saturation, causing part of the power to be lost to the other side.
Metal type – not every steel attracts identically. Alloy additives weaken the attraction effect.
Surface quality – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
Temperature – heating the magnet causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.

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

Safe handling of neodymium magnets

Do not underestimate power

Handle magnets consciously. Their immense force can surprise even professionals. Plan your moves and respect their power.

Dust is flammable

Dust generated during grinding of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.

Data carriers

Equipment safety: Neodymium magnets can ruin payment cards and delicate electronics (heart implants, medical aids, timepieces).

Magnetic interference

A strong magnetic field interferes with the operation of compasses in phones and GPS navigation. Maintain magnets near a device to prevent breaking the sensors.

Warning for heart patients

Individuals with a pacemaker have to keep an absolute distance from magnets. The magnetism can interfere with the functioning of the life-saving device.

Protective goggles

Despite metallic appearance, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.

No play value

Product intended for adults. Tiny parts pose a choking risk, causing serious injuries. Store away from kids and pets.

Finger safety

Risk of injury: The attraction force is so great that it can result in hematomas, pinching, and even bone fractures. Use thick gloves.

Allergy Warning

Allergy Notice: The nickel-copper-nickel coating contains nickel. If an allergic reaction happens, immediately stop working with magnets and wear gloves.

Maximum temperature

Do not overheat. Neodymium magnets are susceptible to heat. If you need operation above 80°C, look for special high-temperature series (H, SH, UH).
