Pulling power weakens significantly per each millimeter of spacing. Note that even a microscopic distance (e.g., dirt, paint, veneer) strongly weakens the grip. Neodymiums work optimally in perfect adhesion; gap kills the force. Notice how rapidly the parameters drop, when the magnet does not touch tightly to the metal substrate. When calculating the arrangement, discard additional spacers.

This section indicates the estimated shear load sufficient to cause the downward movement of the magnet vertically against a vertical metal surface (assuming standard friction). This parameter is relative to the gap size between the magnet and the metal.

Table 3: Vertical assembly (sliding) - vertical pull

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

When placing a element on a vertical surface (e.g., a car body), it you can count on just approx. 1/5 of nominal attraction strength. Gravitational force as well as a weak degree of grip influence the fact that holders slide down faster than they detach. Planning a vertical fastening? Consider that the sliding force is noticeably lower than the perpendicular breakaway force. On a smooth steel, the holder will slip down under a much lighter weight. Application of an anti-slip layer can effectively raise the stability.

A thin metal plate cannot take in the full magnetic flux, 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 pull force will drop sharply. To utilize 100% of this magnet's power, you need a suitably thick element of metal. The saturation phenomenon means that on thin elements (e.g., thin profiles), the magnet holds weaker. We recommend selecting the steel dimension based on the following data.

Standard neodymium magnets irreversibly lose strength after exceeding the maximum temperature. Watch out for overheating – high temperature can irreversibly damage this product. With increasing heat, the neodymium's capacity briefly decreases. Refrain from using this magnet in hot environments exceeding its safe range. Exceeding the critical threshold will cause irreversible degradation of magnetism.

*Engineering note: Thermal stability is determined by both grade, and the Permeance Coefficient Pc. Thin magnets (low Pc) may lose charge permanently at lower temperatures than long magnets. The danger warning in the table points to a risk of irreversible loss for this particular item.

Two strong neodymiums attract each other from a significantly greater distance than a magnet and steel setup. Such a system of magnet-to-magnet generates a stronger field and a further horizon of action. Want to build a powerful holder? Utilize two neodymiums instead of a neodymium and a striker plate. Remember that when attracting two neodymiums, the pinch force is massive. The levitation is marginally weaker than the attraction, but still impressive.
*The magnetic induction for N-N configuration drops to ~0 Gs at the midpoint of the gap (resulting from vector opposition).
Attention: Calculations apply to sliding force of two same neodymium magnets (friction coefficient ~0.15 for Ni-Ni plating).

Extremely neodym field poses a real danger to IT equipment as well as medical implants. These NdFeB products generate a field that destroys function of digital equipment. Be aware: the invisible magnetic field penetrates the body and plastic. Exceptional care must be taken by people with hearing aids and insulin pumps. Also at risk are: mechanical watches, car keys, membranes, and screens. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Table 8: Dynamics (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 strong collision with metal can result in shattering. Watch the impact speed – a magnet released freely speeds with massive force. Kinetic force can destroy the magnet or painful pinches to fingers. Be sure to control the product during installation so it doesn't hit violently against the steel surface. A collision at high speed almost guarantees destruction of the magnet. Use safety goggles when playing with powerful specimens.

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

Water displaces steel, making heavy objects slightly lighter. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Shear force

*Caution: On a vertical surface, the magnet holds merely ~20% of its max power.

2. Steel thickness impact

*Thin steel (e.g. 0.5mm PC case) drastically weakens the holding force.

3. Power loss vs temp

*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

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.

This product is an extremely powerful rod magnet, composed of modern NdFeB material, which, at dimensions of Ø10x4 mm, guarantees optimal power. This specific item boasts high dimensional repeatability and industrial build quality, making it an ideal solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 2.80 kg), this product is in stock from our warehouse in Poland, ensuring rapid order fulfillment. Moreover, its Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

It finds application in DIY projects, advanced robotics, and broadly understood industry, serving as a fastening or actuating element. Thanks to the high power of 27.42 N with a weight of only 2.36 g, this rod is indispensable in electronics and wherever every gram matters.

Due to the brittleness of the NdFeB material, you must not use force-fitting (so-called press-fit), as this risks immediate cracking of this professional 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 high repeatability of the connection.

Grade N38 is the most popular standard for professional neodymium magnets, offering a great economic balance and high resistance to demagnetization. If you need even stronger 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.

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. Such an arrangement is standard 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 diametrically if your project requires it.

Pros and cons of rare earth magnets.

Strengths

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

They have unchanged lifting capacity, and over more than 10 years their attraction force decreases symbolically – ~1% (according to theory),
They have excellent resistance to weakening of magnetic properties due to opposing magnetic fields,
By using a shiny layer of nickel, the element acquires an elegant look,
Neodymium magnets generate maximum magnetic induction on a contact point, which allows for strong attraction,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
Possibility of exact machining and modifying to individual requirements,
Versatile presence in high-tech industry – they are utilized in HDD drives, motor assemblies, advanced medical instruments, and complex engineering applications.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which allows their use in small systems

Cons

Drawbacks and weaknesses of neodymium magnets: weaknesses and usage proposals

They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
Neodymium magnets lose 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 durability even at temperatures up to 230°C
Magnets exposed to a humid environment can rust. Therefore when using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
Limited ability of producing threads in the magnet and complicated forms - recommended is a housing - magnetic holder.
Potential hazard resulting from small fragments of magnets are risky, in case of ingestion, which is particularly important in the context of child health protection. Furthermore, small elements of these products can complicate diagnosis medical after entering the body.
Due to expensive raw materials, their price is relatively high,

Pull force analysis

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

The declared magnet strength refers to the maximum value, measured under laboratory conditions, namely:

using a sheet made of high-permeability steel, functioning as a magnetic yoke
possessing a thickness of min. 10 mm to avoid saturation
characterized by even structure
under conditions of no distance (surface-to-surface)
under vertical force direction (90-degree angle)
at standard ambient temperature

Practical aspects of lifting capacity – factors

Bear in mind that the magnet holding will differ influenced by elements below, starting with the most relevant:

Gap between surfaces – every millimeter of distance (caused e.g. by veneer or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
Angle of force application – maximum parameter is available only during perpendicular pulling. The resistance to sliding of the magnet along the surface is typically several 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.
Material type – ideal substrate is high-permeability steel. Hardened steels may have worse magnetic properties.
Surface condition – smooth surfaces ensure maximum contact, which improves field saturation. Uneven metal weaken the grip.
Temperature influence – high temperature weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity testing was carried out on a smooth plate of suitable thickness, under a perpendicular pulling force, however under attempts to slide the magnet the holding force is lower. Moreover, even a small distance between the magnet and the plate reduces the holding force.

Warnings

Dust is flammable

Fire warning: Rare earth powder is explosive. Avoid machining magnets without safety gear as this risks ignition.

Keep away from electronics

Be aware: rare earth magnets produce a field that disrupts sensitive sensors. Keep a safe distance from your mobile, device, and navigation systems.

Medical interference

Medical warning: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have electronic implants.

Metal Allergy

Nickel alert: The nickel-copper-nickel coating contains nickel. If redness appears, cease working with magnets and wear gloves.

Thermal limits

Do not overheat. NdFeB magnets are susceptible to heat. If you need resistance above 80°C, ask us about HT versions (H, SH, UH).

Electronic devices

Do not bring magnets near a wallet, laptop, or TV. The magnetism can destroy these devices and wipe information from cards.

Product not for children

Always store magnets away from children. Risk of swallowing is high, and the effects of magnets clamping inside the body are very dangerous.

Respect the power

Handle with care. Rare earth magnets act from a long distance and connect with huge force, often quicker than you can react.

Bodily injuries

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

Shattering risk

Beware of splinters. Magnets can explode upon uncontrolled impact, ejecting shards into the air. We recommend safety glasses.
