Grip strength decreases significantly per each millimeter of gap. Note that every additional insulation layer (e.g., dirt, paint, dust) significantly diminishes the holding power. Magnetic products hold optimally at the point of direct contact; gap drastically cuts the power. Analyze how rapidly the pull force drop, when the product does not touch flatly to the metal substrate. When planning the mounting, discard additional spacers.

This section calculates the theoretical shear load needed to initiate the sliding of the magnet vertically against a upright steel plate (assuming standard friction coefficient). This value is relative to the air gap between the magnet and the surface.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces
MW 10x4 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.84 kg / 1.85 LBS 840.0 g / 8.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.56 kg / 1.23 LBS 560.0 g / 5.5 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.28 kg / 0.62 LBS 280.0 g / 2.7 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.40 kg / 3.09 LBS 1400.0 g / 13.7 N

When placing a holder on a upright plane (e.g., a car body), it you can count on just about 1/5 of its nominal power. Gravity and a low friction coefficient influence the fact that products slide down easier than they detach. Designing a hanger? Remember that the shear force is much weaker than the perpendicular breakaway force. On a smooth steel, the holder will give way down under a noticeably lighter cargo. Application of an anti-slip pad can significantly raise the stability.

12 mm	100%	2.80 kg / 6.17 LBS 2800.0 g / 27.5 N

A too thin steel is unable to conduct the full magnetic flux, which squanders power of the magnet. Should you install a neodymium to a thin surface, the field will pass right through and the attraction force will be weaker. To utilize full efficiency of this neodymium's power, you need a suitably thick element of steel. The saturation effect causes that on delicate walls (e.g., appliance housings), the magnet shows lower pull force. We recommend selecting the steel dimension based on the following data.

Ordinary NdFeB products change their properties strength after exceeding the maximum temperature. Protect against heat – heat can permanently demagnetize this product. With every degree above norm, the neodymium's power temporarily lowers. Avoid using this product close to heaters exceeding its operating temperature limit. Ignoring the limit will result in irreversible degradation of magnetic properties.

*Important note: Heat tolerance depends not only on the material grade, but also on the magnet's shape. Low-profile magnets (low Pc) may lose charge permanently sooner compared to rod magnets. Red status in the table signals a risk of irreversible loss for this particular item.

Two strong neodymiums interact from a much further distance than a neodymium and metal setup. The connection of two magnets produces a massive flux and a larger range of operation. Want to build a strong closure? Use a pair of magnets instead of one magnet and a striker plate. Exercise caution that when attracting two neodymiums, the impact force is massive. The levitation is slightly lower than the connection force, but still impressive.
*Flux density between like poles drops to ~0 Gs in the exact middle of the gap (resulting from vector opposition).
Note: Calculations refer to sliding force of two same neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

Table 7: Hazards (electronics) - precautionary measures

Extremely neodym field is a real danger to electronics as well as pacemakers. These NdFeB products produce a flux that disrupts operation of sensitive medical devices. Notice: the unseen radiation passes through tissues and housings. Special caution must be taken by people with hearing aids and drug dispensers. Also at risk are: automatic timepieces, remotes, speakers, and screens. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

Table 8: Impact energy (kinetic energy) - collision effects
MW 10x4 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	34.86 km/h (9.68 m/s)	0.11 J
30 mm	60.17 km/h (16.71 m/s)	0.33 J
50 mm	77.68 km/h (21.58 m/s)	0.55 J
100 mm	109.85 km/h (30.51 m/s)	1.10 J

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

Corrosion warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

The magnetic field penetrates through water without any losses. However, remember the water resistance when pulling the rope quickly.

1. Shear force

*Caution: On a vertical surface, the magnet holds merely a fraction of its max power.

2. Steel thickness impact

*Thin metal sheet (e.g. computer case) drastically weakens the holding force.

3. Heat tolerance

*For N38 grade, the critical limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.50

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 exceptionally strong cylindrical magnet, composed of advanced NdFeB material, which, with dimensions of Ø10x4 mm, guarantees maximum efficiency. The MW 10x4 / N38 model boasts an accuracy of ±0.1mm and professional build quality, making it a perfect solution for the most demanding engineers and designers. As a cylindrical magnet with impressive force (approx. 2.80 kg), this product is in stock from our European logistics center, ensuring rapid order fulfillment. Furthermore, its Ni-Cu-Ni coating effectively protects it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is perfect for building generators, advanced sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the pull force of 27.42 N with a weight of only 2.36 g, this cylindrical magnet is indispensable in miniature devices and wherever every gram matters.

Due to the delicate structure of the ceramic sinter, we absolutely advise against force-fitting (so-called press-fit), as this risks immediate cracking of this precision component. To ensure long-term durability in industry, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.

Magnets NdFeB grade N38 are strong enough for 90% of applications in automation and machine building, where excessive miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø10x4), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.

The presented product is a neodymium magnet with precisely defined parameters: diameter 10 mm and height 4 mm. The value of 27.42 N means that the magnet is capable of holding a weight many times exceeding its own mass of 2.36 g. 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 4 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.

Advantages and disadvantages of Nd₂Fe₁₄B magnets.

Benefits

Besides their durability, neodymium magnets are valued for these benefits:

They do not lose magnetism, even during nearly ten years – the reduction in strength is only ~1% (theoretically),
Magnets perfectly resist against demagnetization caused by foreign field sources,
Thanks to the elegant finish, the surface of nickel, gold-plated, or silver gives an modern appearance,
Magnets are distinguished by excellent magnetic induction on the outer side,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
Possibility of precise machining and modifying to complex conditions,
Fundamental importance in modern industrial fields – they are commonly used in mass storage devices, electric drive systems, precision medical tools, also complex engineering applications.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Cons

Characteristics of disadvantages of neodymium magnets: weaknesses and usage proposals

They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also increases its resistance to damage
NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
Due to limitations in creating threads and complex shapes in magnets, we propose using casing - magnetic mechanism.
Health risk related to microscopic parts of magnets can be dangerous, in case of ingestion, which becomes key in the aspect of protecting the youngest. It is also worth noting that tiny parts of these products are able to be problematic in diagnostics medical in case of swallowing.
With large orders the cost of neodymium magnets can be a barrier,

Holding force characteristics

Maximum lifting force for a neodymium magnet – what contributes to it?

Magnet power was defined for optimal configuration, assuming:

using a plate made of mild steel, functioning as a magnetic yoke
possessing a massiveness of at least 10 mm to ensure full flux closure
with an polished contact surface
under conditions of no distance (surface-to-surface)
for force applied at a right angle (pull-off, not shear)
at ambient temperature room level

Impact of factors on magnetic holding capacity in practice

Bear in mind that the application force may be lower influenced by the following factors, in order of importance:

Distance (between the magnet and the metal), because even a tiny clearance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
Load vector – highest force is available only during perpendicular pulling. The resistance to sliding of the magnet along the surface is usually many times lower (approx. 1/5 of the lifting capacity).
Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
Steel grade – ideal substrate is pure iron steel. Stainless steels may attract less.
Smoothness – full contact is obtained only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
Temperature – heating the magnet causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.

Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate reduces the holding force.

H&S for magnets

Caution required

Use magnets consciously. Their powerful strength can surprise even professionals. Stay alert and do not underestimate their power.

No play value

NdFeB magnets are not intended for children. Eating several magnets may result in them connecting inside the digestive tract, which poses a severe health hazard and requires immediate surgery.

Cards and drives

Very strong magnetic fields can erase data on payment cards, hard drives, and other magnetic media. Stay away of at least 10 cm.

Fire risk

Machining of neodymium magnets carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.

Phone sensors

Be aware: rare earth magnets produce a field that disrupts sensitive sensors. Keep a safe distance from your phone, tablet, and GPS.

Power loss in heat

Keep cool. Neodymium magnets are susceptible to temperature. If you need operation above 80°C, ask us about special high-temperature series (H, SH, UH).

Nickel coating and allergies

Nickel alert: The nickel-copper-nickel coating consists of nickel. If an allergic reaction happens, cease working with magnets and wear gloves.

Risk of cracking

NdFeB magnets are ceramic materials, which means they are fragile like glass. Impact of two magnets will cause them breaking into shards.

Life threat

Warning for patients: Strong magnetic fields affect medical devices. Keep minimum 30 cm distance or request help to work with the magnets.

Bodily injuries

Pinching hazard: The attraction force is so immense that it can cause blood blisters, pinching, and broken bones. Protective gloves are recommended.
