Grip strength drops significantly with every mm of spacing. Keep in mind that even the smallest gap (e.g., dirt, varnish, rust) significantly reduces the pull force. Neodymiums hold strongest in perfect adhesion; air break weakens the power. Observe how quickly the pull force drop, when the magnet does not touch tightly to the steel surface. When planning the mounting, avoid unnecessary gaps.

The following data shows the approximate holding capacity needed to cause the sliding of the magnet down along a upright steel plate (assuming typical friction coefficient). The holding force depends on the gap size between the magnet and the surface.

Table 3: Wall mounting (shearing) - behavior on slippery surfaces

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	2.01 kg / 4.44 LBS 2013.0 g / 19.7 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.34 kg / 2.96 LBS 1342.0 g / 13.2 N

Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	3.36 kg / 7.40 LBS 3355.0 g / 32.9 N

When mounting a element on a upright plane (e.g., a fridge), it will maintain just approx. 1/5 of its nominal power. Gravitational force as well as a weak degree of grip mean that magnets move down easier than they pop off the substrate. Planning a wall mount? Consider that the sliding force is much weaker than the maximum static pull force. On a smooth steel, the element will slip down under a much lighter load. Using a rubber layer can significantly raise the stability.

A thin sheet cannot absorb the full magnetic flux, which weakens actual performance of the holder. If you attach a powerful product to a thin surface, the flux will pass right through and the holding will be smaller. To utilize the maximum of this neodymium's potential, you need a suitably thick piece of metal. The saturation phenomenon causes that on sheet metal structures (e.g., thin profiles), the product works worse. We suggest choosing the steel dimension from these parameters.

Ordinary NdFeB products change their properties parameters after exceeding the maximum temperature. Protect against heat – high temperature can irreversibly destroy this magnet. With increasing heat, the neodymium's force briefly drops. Do not use this magnet near heat sources higher than its safe range. Exceeding the critical threshold will lead to irreversible degradation of magnetic properties.

*Technical advisory: Temperature resistance is determined by both grade, and the Permeance Coefficient Pc. Flat magnets (low permeance coefficient) may lose charge permanently at lower temperatures than taller cylinders. The danger warning in the table indicates permanent field degradation for this specific geometry.

Two magnetic products interact from a wider radius than a neodymium and metal setup. The setup of magnet-to-magnet creates a more powerful interaction and a wider radius of performance. Designing a powerful holder? Utilize two neodymiums instead of one magnet and a striker plate. Be careful that when connecting a pair of magnets, the collision energy is extreme. The levitation is a bit weaker than the connection force, but still impressive.
*Field value in repulsion mode is approximately ~0 Gs at the midpoint between the magnets (due to field cancellation).
Important: Estimates show sliding force of two same neodymium magnets (friction coefficient ~0.15 for Ni-Ni plating).

Powerful magnet radiation poses a serious hazard to electronic devices as well as medical implants. These magnets produce a field that destroys function of sensitive medical devices. Remember: the invisible magnetic field penetrates the body and plastic. Special caution must be taken by people with cochlear implants and insulin pumps. The risk also applies to: automatic timepieces, remotes, speakers, and screens. Avoid contact with magnetic cards, HDD media, or sensitive navigation tools.

Neodymium magnets are delicate – a collision with steel causes immediate chipping. Watch the impact speed – a magnet released freely turns into a projectile. Kinetic force can trigger coating fragments or painful pinches to fingers. Hold the magnet firmly during mounting so it doesn't hit with great force against the metal. A collision at high speed means shattering of the magnet. Wear safety glasses when handling 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. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Wall mount (shear)

*Caution: On a vertical surface, the magnet retains merely a fraction of its nominal pull.

2. Steel saturation

*Thin metal sheet (e.g. 0.5mm PC case) drastically reduces the holding force.

3. Thermal stability

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.74

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 an extremely powerful cylinder magnet, manufactured from modern NdFeB material, which, with dimensions of Ø14x10 mm, guarantees maximum efficiency. This specific item features high dimensional repeatability and industrial build quality, making it an excellent solution for the most demanding engineers and designers. As a cylindrical magnet with significant force (approx. 6.71 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring rapid order fulfillment. Furthermore, its Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.

It finds application in modeling, advanced robotics, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 65.83 N with a weight of only 11.55 g, this rod 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., 14.1 mm) using two-component epoxy glues. To ensure stability in industry, specialized industrial adhesives 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 (Ø14x10), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.

This model is characterized by dimensions Ø14x10 mm, which, at a weight of 11.55 g, makes it an element with high magnetic energy density. The key parameter here is the holding force amounting to approximately 6.71 kg (force ~65.83 N), which, with such compact 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.

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 14 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.

Advantages and disadvantages of neodymium magnets.

Advantages

Apart from their consistent holding force, neodymium magnets have these key benefits:

They have constant strength, and over more than ten years their performance decreases symbolically – ~1% (according to theory),
They feature excellent resistance to weakening of magnetic properties when exposed to external fields,
By covering with a lustrous coating of nickel, the element acquires an aesthetic look,
They are known for high magnetic induction at the operating surface, which affects their effectiveness,
Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures reaching 230°C and above...
Thanks to versatility in constructing and the capacity to modify to unusual requirements,
Fundamental importance in advanced technology sectors – they are utilized in hard drives, motor assemblies, precision medical tools, and technologically advanced constructions.
Thanks to concentrated force, small magnets offer high operating force, in miniature format,

Disadvantages

Problematic aspects of neodymium magnets and ways of using them

They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
Neodymium magnets decrease their force 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 start to 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 ability of making nuts in the magnet and complex shapes - preferred is casing - magnetic holder.
Potential hazard resulting from small fragments of magnets are risky, when accidentally swallowed, which becomes key in the context of child health protection. Additionally, small components of these devices are able to complicate diagnosis medical when they are in the body.
With budget limitations the cost of neodymium magnets can be a barrier,

Pull force analysis

Maximum lifting force for a neodymium magnet – what affects it?

Information about lifting capacity was determined for ideal contact conditions, taking into account:

using a base made of mild steel, serving as a magnetic yoke
possessing a massiveness of minimum 10 mm to ensure full flux closure
with an polished contact surface
with total lack of distance (without coatings)
under perpendicular force vector (90-degree angle)
in stable room temperature

Magnet lifting force in use – key factors

Please note that the working load will differ subject to elements below, in order of importance:

Distance – existence of any layer (paint, dirt, air) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
Load vector – highest force is reached only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is typically several times lower (approx. 1/5 of the lifting capacity).
Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
Plate material – low-carbon steel gives the best results. Alloy admixtures decrease magnetic permeability and holding force.
Smoothness – ideal contact is obtained only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
Thermal factor – high temperature reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity testing was conducted on a smooth plate of optimal thickness, under perpendicular forces, in contrast under shearing force the load capacity is reduced by as much as 75%. In addition, even a small distance between the magnet and the plate lowers the lifting capacity.

Safety rules for work with neodymium magnets

Metal Allergy

Studies show that the nickel plating (the usual finish) is a strong allergen. If you have an allergy, refrain from touching magnets with bare hands and choose versions in plastic housing.

Pacemakers

For implant holders: Powerful magnets affect medical devices. Keep at least 30 cm distance or request help to handle the magnets.

Immense force

Use magnets with awareness. Their immense force can surprise even experienced users. Be vigilant and respect their force.

Threat to electronics

Avoid bringing magnets close to a purse, computer, or TV. The magnetism can destroy these devices and wipe information from cards.

Heat sensitivity

Watch the temperature. Heating the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and pulling force.

Magnetic interference

GPS units and smartphones are highly susceptible to magnetism. Close proximity with a powerful NdFeB magnet can permanently damage the sensors in your phone.

Crushing force

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

Material brittleness

Beware of splinters. Magnets can fracture upon violent connection, launching sharp fragments into the air. We recommend safety glasses.

Dust explosion hazard

Powder produced during machining of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.

Do not give to children

Absolutely store magnets out of reach of children. Risk of swallowing is high, and the effects of magnets connecting inside the body are life-threatening.
