Pulling power drops sharply with every mm of distance. Keep in mind that even a microscopic distance (e.g., dirt, paint, veneer) noticeably weakens the grip. Neodymiums hold strongest during direct contact; distance nullifies the force. Observe how flashily the pull force fall, when the magnet does not touch directly to the metal substrate. When planning the mounting, avoid redundant distances.

The table below defines the estimated holding capacity required to cause the downward movement of the magnet downwards on a vertical steel plate (considering standard friction coefficient). The holding force varies with the gap size between the magnet and the surface.

Table 3: Wall mounting (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 mounting a magnet on a upright wall (e.g., a fridge), it will maintain barely approx. 1/5 of its maximum pull force. Gravity and a low friction coefficient cause that products slip easier than they pop off the substrate. Designing a wall mount? Note that the shear force is much weaker than the perpendicular breakaway force. On a painted metal, the element will give way down under a significantly smaller weight. Using a rubber pad can significantly increase the grip.

A thin metal plate is unable to absorb the entire magnetic field, which weakens actual performance of the holder. If you install a neodymium to a thin surface, the field will pass right through and the holding will be smaller. To utilize the maximum of this magnet's power, you require a sufficiently solid backing of steel. The saturation phenomenon means that on sheet metal structures (e.g., appliance housings), the holder shows lower pull force. We recommend selecting the steel cross-section according to the table below.

Standard neodymium magnets change their properties parameters above the temperature limit. Watch out for overheating – heat can permanently damage this product. With every degree above norm, the magnet's capacity momentarily decreases. Refrain from using this product close to heaters exceeding its safe range. Ignoring the limit will lead to destruction of magnetism.

*Engineering note: Heat tolerance is determined by both grade, and the Permeance Coefficient Pc. Thin magnets (low permeance coefficient) may lose charge permanently at lower temperatures than taller cylinders. The danger warning in the table signals a risk of irreversible loss for this specific geometry.

Two magnetic products interact from a wider radius than a magnet and steel combination. The connection of two magnets generates a stronger field and a wider radius of performance. Want to build a solid fastener? Use a pair of magnets instead of a neodymium and a steel. Exercise caution that when bringing together two magnets, the impact force is massive. The levitation is a bit weaker than the connection force, but still impressive.
*Flux density between like poles reaches ~0 Gs in the exact middle of the gap (resulting from vector opposition).
Note: Calculations demonstrate friction force of a pair of same magnets (friction coefficient ~0.15 for Ni-Ni coating).

Extremely neodym field poses a large risk to electronics and medical implants. These neodymiums generate a field that destroys function of sensitive medical devices. Notice: the invisible magnetic field acts through matter and plastic. Exceptional care must be taken by people with hearing aids and insulin pumps. Influence will be felt by: automatic timepieces, remotes, membranes, and screens. Do not place the magnet near cards, hard drives, or precise measuring instruments.

Table 8: Collisions (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

NdFeB products are prone to chipping – a strong collision with metal causes immediate chipping. Watch the impact speed – a neodymium left loose becomes dangerous. Impact energy can trigger coating fragments or dangerous crushing to skin. Be sure to control the product during mounting so it doesn't hit violently against the steel surface. A contact at a velocity of dozens of km/h means shattering of the neodymium. Use safety goggles when working with powerful specimens.

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. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Sliding resistance

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

2. Steel saturation

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

3. Thermal stability

*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) = 0.89

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 incredibly powerful rod magnet, composed of advanced NdFeB material, which, with dimensions of Ø10x10 mm, guarantees the highest energy density. This specific item is characterized by a tolerance of ±0.1mm and industrial build quality, making it a perfect solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 3.18 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring quick order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

It successfully proves itself in DIY projects, advanced automation, and broadly understood industry, serving as a positioning or actuating element. Thanks to the pull force of 31.15 N with a weight of only 5.89 g, this cylindrical magnet is indispensable in electronics and wherever low weight is crucial.

Since our magnets have a tolerance of ±0.1mm, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 10.1 mm) using two-component epoxy glues. To ensure long-term durability in industry, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.

Magnets NdFeB grade N38 are suitable 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 (Ø10x10), 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 Ø10x10 mm, which, at a weight of 5.89 g, makes it an element with impressive magnetic energy density. 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 secures it 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 through the diameter if your project requires it.

Advantages and disadvantages of neodymium magnets.

Pros

In addition to their long-term stability, neodymium magnets provide the following advantages:

They do not lose magnetism, even over approximately 10 years – the reduction in strength is only ~1% (according to tests),
They are noted for resistance to demagnetization induced by presence of other magnetic fields,
By applying a reflective layer of silver, the element acquires an aesthetic look,
Magnets are characterized by impressive magnetic induction on the active area,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
Thanks to versatility in shaping and the capacity to adapt to specific needs,
Huge importance in high-tech industry – they are commonly used in computer drives, electromotive mechanisms, diagnostic systems, as well as modern systems.
Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which allows their use in small systems

Weaknesses

Disadvantages of NdFeB magnets:

Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a special holder, which not only secures them against impacts but also raises their durability
When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their strength 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
They rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
We suggest cover - magnetic mount, due to difficulties in creating nuts inside the magnet and complicated forms.
Potential hazard resulting from small fragments of magnets pose a threat, in case of ingestion, which gains importance in the aspect of protecting the youngest. Additionally, tiny parts of these products are able to disrupt the diagnostic process medical after entering the body.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Holding force characteristics

Best holding force of the magnet in ideal parameters – what contributes to it?

Holding force of 3.18 kg is a theoretical maximum value performed under the following configuration:

on a plate made of structural steel, optimally conducting the magnetic field
whose transverse dimension is min. 10 mm
with an polished touching surface
with zero gap (no paint)
for force applied at a right angle (pull-off, not shear)
in neutral thermal conditions

Impact of factors on magnetic holding capacity in practice

It is worth knowing that the application force will differ influenced by elements below, starting with the most relevant:

Space between magnet and steel – every millimeter of separation (caused e.g. by varnish or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
Force direction – declared lifting capacity refers to pulling vertically. When slipping, the magnet exhibits much less (typically approx. 20-30% of maximum force).
Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
Steel type – mild steel gives the best results. Alloy steels decrease magnetic permeability and holding force.
Surface condition – ground elements ensure maximum contact, which improves field saturation. Uneven metal weaken the grip.
Operating temperature – NdFeB sinters have a negative temperature coefficient. At higher temperatures they are weaker, and in frost gain strength (up to a certain limit).

Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate reduces the load capacity.

Safety rules for work with NdFeB magnets

Handling guide

Before starting, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.

Metal Allergy

It is widely known that nickel (the usual finish) is a common allergen. For allergy sufferers, prevent direct skin contact or choose versions in plastic housing.

Cards and drives

Intense magnetic fields can erase data on credit cards, HDDs, and other magnetic media. Stay away of at least 10 cm.

Danger to the youngest

Neodymium magnets are not toys. Eating several magnets may result in them pinching intestinal walls, which constitutes a severe health hazard and requires immediate surgery.

Thermal limits

Avoid heat. NdFeB magnets are susceptible to temperature. If you require operation above 80°C, ask us about HT versions (H, SH, UH).

Bodily injuries

Large magnets can break fingers instantly. Do not place your hand between two attracting surfaces.

Compass and GPS

Remember: rare earth magnets produce a field that interferes with sensitive sensors. Keep a safe distance from your phone, tablet, and navigation systems.

Danger to pacemakers

Life threat: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have electronic implants.

Fire warning

Fire hazard: Neodymium dust is explosive. Do not process magnets in home conditions as this risks ignition.

Beware of splinters

NdFeB magnets are sintered ceramics, which means they are fragile like glass. Collision of two magnets leads to them shattering into small pieces.
