Magnetic force drops significantly with every mm of spacing. Note that even the smallest gap (e.g., contamination, varnish, dust) noticeably diminishes the holding power. Neodymiums work optimally in perfect adhesion; air break drastically cuts the force. See how quickly the load capacity drop, when the product does not adhere directly to the steel surface. When calculating the assembly, discard unnecessary gaps.

MW 10x10 / N38

The table below indicates the estimated force sufficient to cause the shifting of the magnet vertically on a vertical steel wall (considering typical friction coefficient). The holding force depends on the separation distance between the magnet and the surface.

Table 3: Vertical assembly (shearing) - vertical pull
MW 10x10 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.95 kg / 2.10 lbs 954.0 g / 9.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.64 kg / 1.40 lbs 636.0 g / 6.2 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.32 kg / 0.70 lbs 318.0 g / 3.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.59 kg / 3.51 lbs 1590.0 g / 15.6 N

When hanging a magnet on a upright plane (e.g., a car body), it you can count on only about 1/5 of nominal attraction strength. Gravitational force and a low friction coefficient mean that holders slide down easier than they pull off. Designing a vertical fastening? Consider that the sliding force is significantly lower than the perpendicular breakaway force. On a smooth steel, the holder will slide down under a significantly smaller weight. Using a rubber layer can significantly increase the grip.

3 mm	75%	2.39 kg / 5.26 lbs 2385.0 g / 23.4 N
5 mm	100%	3.18 kg / 7.01 lbs 3180.0 g / 31.2 N
10 mm	100%	3.18 kg / 7.01 lbs 3180.0 g / 31.2 N

12 mm	100%	3.18 kg / 7.01 lbs 3180.0 g / 31.2 N

A too thin steel is unable to absorb the entire magnetic field, which wastes potential of the holder. If you mount a strong magnet to a too thin substrate, the field will pass right through and the pull force will drop sharply. To utilize full efficiency of this neodymium's power, you need a suitably thick backing of metal. The saturation phenomenon means that on delicate walls (e.g., car bodies), the magnet holds weaker. We suggest choosing the steel cross-section according to the table below.

Ordinary NdFeB products lose parameters past the thermal threshold. Watch out for overheating – excessive heat can irreversibly demagnetize this product. With increasing heat, the neodymium's power briefly decreases. Do not use this magnet in hot environments exceeding its working range. Too high temperature will lead to permanent loss of magnetism.

*Engineering note: Thermal stability is determined by both grade, as well as the dimension ratios. Thin magnets (low Pc) are more susceptible to demagnetization at lower temperatures than long magnets. Warning indicator in the table points to a risk of irreversible loss for this particular item.

Two magnets attract each other from a much further distance than a magnet and sheet setup. Such a system of magnet-to-magnet produces a massive flux and a larger range of action. Designing a solid fastener? Apply two magnets instead of one magnet and a striker plate. Remember that when attracting two neodymiums, the collision energy is massive. The repulsion force is marginally weaker than the attraction, but still impressive.
*Flux density in repulsion mode reaches ~0 Gs in the exact middle between the magnets (resulting from vector opposition).
* Figures refer to shear force of two matching neodymium magnets (friction ~0.15 for Ni-Ni layer).

A strong magnetic field is a large risk to electronics as well as medical implants. These NdFeB products produce a field that destroys function of sensitive medical devices. Remember: the invisible magnetic field passes through tissues and plastic. Special caution must be taken by people with hearing aids and drug dispensers. The risk also applies to: mechanical watches, car keys, speakers, and displays. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Table 8: Impact energy (kinetic energy) - collision effects
MW 10x10 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	23.54 km/h (6.54 m/s)	0.13 J

100 mm	74.10 km/h (20.58 m/s)	1.25 J

Magnetic elements are very brittle – a violent impact against metal can result in shattering. Control the attraction moment – a magnet released freely turns into a projectile. Impact energy can destroy the magnet or dangerous crushing to fingers. Always hold the magnet during bringing near metal so it doesn't hit with great force against the steel surface. A collision at high speed almost guarantees destruction of the magnet. Use safety goggles when handling with large magnets.

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

In water, the magnet feels stronger thanks to Archimedes' principle. Buoyancy helps in lifting finds.

1. Shear force

*Warning: On a vertical wall, the magnet holds only a fraction of its max power.

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 safety limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.89

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 presented product is a very strong cylinder magnet, composed of advanced NdFeB material, which, at dimensions of Ø10x10 mm, guarantees maximum efficiency. This specific item is characterized by high dimensional repeatability and professional build quality, making it a perfect solution for the most demanding engineers and designers. As a magnetic rod with impressive force (approx. 3.18 kg), this product is in stock from our European logistics center, ensuring rapid 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.

This model is created for building electric motors, advanced sensors, and efficient filters, where field concentration on a small surface counts. Thanks to the pull force of 31.15 N with a weight of only 5.89 g, this rod is indispensable in miniature devices and wherever low weight is crucial.

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 precision component. To ensure stability in automation, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.

Magnets NdFeB grade N38 are suitable for 90% of applications in modeling and machine building, where extreme miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø10x10), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.

The presented product is a neodymium magnet with precisely defined parameters: diameter 10 mm and height 10 mm. The value of 31.15 N means that the magnet is capable of holding a weight many times exceeding its own mass of 5.89 g. 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. 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 Nd₂Fe₁₄B magnets.

Pros

Besides their exceptional magnetic power, neodymium magnets offer the following advantages:

They virtually do not lose strength, because even after ten years the performance loss is only ~1% (in laboratory conditions),
Neodymium magnets are distinguished by highly resistant to loss of magnetic properties caused by magnetic disturbances,
In other words, due to the reflective finish of nickel, the element gains a professional look,
Neodymium magnets create maximum magnetic induction on a small surface, which ensures high operational 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...
Thanks to freedom in shaping and the capacity to adapt to specific needs,
Fundamental importance in high-tech industry – they serve a role in HDD drives, electromotive mechanisms, advanced medical instruments, as well as industrial machines.
Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,

Weaknesses

Disadvantages of NdFeB magnets:

Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a steel housing, which not only secures them against impacts but also raises their durability
When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and 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 those in rubber or plastics, which secure oxidation and corrosion.
Limited ability of making threads in the magnet and complicated forms - preferred is a housing - magnet mounting.
Possible danger to health – tiny shards of magnets pose a threat, when accidentally swallowed, which becomes key in the context of child health protection. Furthermore, tiny parts of these magnets can be problematic in diagnostics medical after entering the body.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Pull force analysis

Optimal lifting capacity of a neodymium magnet – what contributes to it?

The declared magnet strength represents the limit force, measured under optimal environment, meaning:

using a sheet made of high-permeability steel, functioning as a circuit closing element
whose thickness is min. 10 mm
with a plane cleaned and smooth
under conditions of ideal adhesion (surface-to-surface)
under axial force direction (90-degree angle)
at standard ambient temperature

Lifting capacity in real conditions – factors

Effective lifting capacity impacted by working environment parameters, such as (from priority):

Gap between magnet and steel – every millimeter of separation (caused e.g. by veneer or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
Force direction – catalog parameter refers to detachment vertically. When applying parallel force, the magnet exhibits significantly lower power (typically approx. 20-30% of nominal force).
Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of generating force.
Steel grade – ideal substrate is high-permeability steel. Stainless steels may generate lower lifting capacity.
Plate texture – ground elements guarantee perfect abutment, which improves force. Rough surfaces weaken the grip.
Heat – NdFeB sinters have a negative temperature coefficient. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).

Lifting capacity was determined by applying a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under attempts to slide the magnet the load capacity is reduced by as much as 5 times. In addition, even a slight gap between the magnet and the plate lowers the lifting capacity.

Warnings

Powerful field

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

Fire warning

Fire hazard: Rare earth powder is explosive. Avoid machining magnets in home conditions as this risks ignition.

Danger to pacemakers

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

Keep away from electronics

A strong magnetic field disrupts the functioning of magnetometers in phones and GPS navigation. Keep magnets near a device to avoid breaking the sensors.

This is not a toy

Adult use only. Tiny parts pose a choking risk, causing severe trauma. Keep away from kids and pets.

Risk of cracking

Protect your eyes. Magnets can fracture upon uncontrolled impact, ejecting shards into the air. Eye protection is mandatory.

Bodily injuries

Watch your fingers. Two powerful magnets will snap together instantly with a force of massive weight, crushing everything in their path. Exercise extreme caution!

Electronic devices

Intense magnetic fields can corrupt files on payment cards, hard drives, and storage devices. Stay away of min. 10 cm.

Sensitization to coating

Some people experience a contact allergy to nickel, which is the typical protective layer for NdFeB magnets. Prolonged contact can result in an allergic reaction. It is best to wear protective gloves.

Do not overheat magnets

Standard neodymium magnets (grade N) lose power when the temperature surpasses 80°C. The loss of strength is permanent.
