Grip strength drops significantly with every subsequent millimeter of gap. Note that even a very thin break (e.g., dirt, varnish, rust) strongly weakens the grip. Neodymiums work most effectively at the point of direct contact; gap weakens the power. Notice how quickly the load capacity drop, when the magnet does not touch flatly to the metal substrate. When designing the mounting, discard redundant distances.

Table 2: Shear capacity (wall)

50 mm	Stal (~0.2)	0.16 kg / 160.0 g 1.6 N

The following data calculates the theoretical shear load required to start the sliding of the magnet vertically along a vertical steel wall (assuming standard friction coefficient). This value varies with the gap size between the magnet and the metal.

Table 3: Vertical assembly (shearing) - vertical pull
MW 55x25 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg)
Raw steel	µ = 0.3 30% Nominalnej Siły	27.68 kg / 27675.0 g 271.5 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	18.45 kg / 18450.0 g 181.0 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	9.23 kg / 9225.0 g 90.5 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	46.13 kg / 46125.0 g 452.5 N

When placing a magnet on a vertical wall (e.g., a fridge), it will only hold only approx. 20%-30% of its nominal power. Gravitational force and a weak degree of grip mean that magnets move down faster than they detach. Planning a wall mount? Consider that the sliding force is much weaker than the perpendicular breakaway force. On a slippery surface, the holder will slip down under a significantly smaller cargo. Using a rubber layer can significantly improve the result.

Table 4: Steel thickness (saturation) - sheet metal selection
MW 55x25 / N38

Steel thickness (mm)	% power	Real pull force (kg)
0.5 mm	3%	3.08 kg / 3075.0 g 30.2 N
1 mm	8%	7.69 kg / 7687.5 g 75.4 N
2 mm	17%	15.37 kg / 15375.0 g 150.8 N
5 mm	42%	38.44 kg / 38437.5 g 377.1 N
10 mm	83%	76.88 kg / 76875.0 g 754.1 N

A thin sheet is not enough to take in the full magnetic flux, which weakens actual performance of the holder. Should you attach a powerful product to a thin surface, the field will penetrate right through and the pull force will drop sharply. To achieve full efficiency of this magnet's potential, you require a sufficiently solid element of steel. The material oversaturation means that on thin elements (e.g., car bodies), the product holds weaker. We advise picking the steel cross-section according to the table below.

Table 5: Thermal resistance (stability) - thermal limit
MW 55x25 / N38

Ambient temp. (°C)	Power loss	Remaining pull	Status
20 °C	0.0%	92.25 kg / 92250.0 g 905.0 N	OK
40 °C	-2.2%	90.22 kg / 90220.5 g 885.1 N	OK
60 °C	-4.4%	88.19 kg / 88191.0 g 865.2 N
80 °C	-6.6%	86.16 kg / 86161.5 g 845.2 N
100 °C	-28.8%	65.68 kg / 65682.0 g 644.3 N

Classic neodymiums change their properties parameters after exceeding the maximum temperature. Watch out for overheating – high temperature can permanently destroy this magnet. With every degree above norm, the magnet's power momentarily lowers. Do not use this magnet in hot environments higher than its operating temperature limit. Too high temperature will cause destruction of magnetic properties.

*Technical advisory: Heat tolerance is determined by both grade, but also on the magnet's shape. Thin magnets (low Pc) may lose charge permanently under lower heat stress compared to rod magnets. Warning indicator in the table points to permanent field degradation for this specific geometry.

Two magnets attract each other from a much further distance than a neodymium and metal combination. Such a system of magnet-to-magnet generates a stronger field and a wider radius of operation. Planning to create a powerful holder? Apply two magnets instead of a neodymium and a striker plate. Remember that when bringing together two magnets, the impact force is extreme. The repulsion force is a bit weaker than the connection force, but still significant.
*Field value for N-N configuration reaches ~0 Gs at the midpoint of the gap (resulting from vector opposition).

Table 7: Hazards (electronics) - warnings
MW 55x25 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	27.5 cm
Hearing aid	10 Gs (1.0 mT)	21.5 cm
Mechanical watch	20 Gs (2.0 mT)	17.0 cm
Phone / Smartphone	40 Gs (4.0 mT)	13.0 cm

Payment card	400 Gs (40.0 mT)	5.0 cm
HDD hard drive	600 Gs (60.0 mT)	4.5 cm

Powerful magnet radiation is a large risk to IT equipment as well as pacemakers. These NdFeB products generate a flux that prevents correct functioning of sensitive medical devices. Be aware: the invisible magnetic field penetrates the body and plastic. Exceptional care must be taken by people with cochlear implants and drug dispensers. Influence will be felt by: automatic timepieces, car keys, speakers, and displays. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Table 8: Impact energy (cracking risk) - collision effects
MW 55x25 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	18.05 km/h (5.01 m/s)	5.60 J
30 mm	25.98 km/h (7.22 m/s)	11.60 J
50 mm	32.63 km/h (9.06 m/s)	18.30 J
100 mm	45.90 km/h (12.75 m/s)	36.21 J

NdFeB products are prone to chipping – a violent impact against metal causes immediate chipping. Pay attention to connection velocity – a magnet released freely turns into a projectile. Striking energy can destroy the magnet or painful pinches to skin. 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. Wear safety glasses when playing with powerful specimens.

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

Water displaces steel, making heavy objects slightly lighter. However, remember the water resistance when pulling the rope quickly.

1. Shear force

*Caution: On a vertical wall, the magnet retains only a fraction of its perpendicular strength.

2. Efficiency vs thickness

*Thin steel (e.g. computer case) severely reduces the holding force.

3. Heat tolerance

*For N38 material, the max working temp is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.55

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 offered product is an extremely powerful cylindrical magnet, manufactured from advanced NdFeB material, which, with dimensions of Ø55x25 mm, guarantees the highest energy density. The MW 55x25 / N38 component features a tolerance of ±0.1mm and industrial build quality, making it an excellent solution for the most demanding engineers and designers. As a magnetic rod with significant force (approx. 92.25 kg), this product is in stock from our European logistics center, ensuring rapid order fulfillment. Additionally, its Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

It finds application in modeling, advanced robotics, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 904.94 N with a weight of only 445.47 g, this rod is indispensable in miniature devices and wherever every gram matters.

Due to the delicate structure of the ceramic sinter, you must not use force-fitting (so-called press-fit), as this risks immediate cracking of this precision component. To ensure long-term durability in automation, specialized industrial adhesives 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 extreme miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø55x25), 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 Ø55x25 mm, which, at a weight of 445.47 g, makes it an element with high magnetic energy density. The value of 904.94 N means that the magnet is capable of holding a weight many times exceeding its own mass of 445.47 g. The product has a [NiCuNi] coating, which protects the surface against external factors, giving it an aesthetic, silvery shine.

This cylinder is magnetized axially (along the height of 25 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.

Strengths and weaknesses of rare earth magnets.

Advantages

Apart from their notable magnetic energy, neodymium magnets have these key benefits:

They do not lose strength, even after around 10 years – the reduction in power is only ~1% (according to tests),
They retain their magnetic properties even under external field action,
The use of an metallic coating of noble metals (nickel, gold, silver) causes the element to present itself better,
Magnetic induction on the working part of the magnet is maximum,
Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
Thanks to modularity in designing and the ability to modify to client solutions,
Wide application in modern technologies – they serve a role in mass storage devices, electromotive mechanisms, advanced medical instruments, and technologically advanced constructions.
Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,

Disadvantages

What to avoid - cons of neodymium magnets and proposals for their use:

Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a steel housing, which not only secures them against impacts but also raises their durability
We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
Magnets exposed to a humid environment can rust. Therefore while using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
We recommend casing - magnetic holder, due to difficulties in realizing threads inside the magnet and complex shapes.
Possible danger related to microscopic parts of magnets pose a threat, in case of ingestion, which becomes key in the context of child safety. It is also worth noting that small components of these devices 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

Holding force characteristics

Maximum lifting force for a neodymium magnet – what it depends on?

Information about lifting capacity was determined for the most favorable conditions, taking into account:

using a plate made of low-carbon steel, acting as a magnetic yoke
possessing a massiveness of min. 10 mm to avoid saturation
characterized by even structure
under conditions of ideal adhesion (surface-to-surface)
during pulling in a direction perpendicular to the mounting surface
at standard ambient temperature

Magnet lifting force in use – key factors

In real-world applications, the real power depends on several key aspects, ranked from the most important:

Air gap (between the magnet and the plate), since even a microscopic clearance (e.g. 0.5 mm) can cause a reduction in lifting capacity by up to 50% (this also applies to varnish, corrosion or dirt).
Loading method – declared lifting capacity refers to detachment vertically. When slipping, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
Steel type – mild steel attracts best. Alloy steels lower magnetic properties and lifting capacity.
Surface quality – the more even the surface, the larger the contact zone and stronger the hold. Roughness creates an air distance.
Temperature influence – high temperature weakens magnetic field. Too high temperature can permanently demagnetize the magnet.

Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under parallel forces the holding force is lower. In addition, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.

Safe handling of neodymium magnets

Respect the power

Handle magnets with awareness. Their huge power can shock even experienced users. Stay alert and respect their force.

Electronic hazard

Avoid bringing magnets close to a purse, computer, or TV. The magnetic field can irreversibly ruin these devices and erase data from cards.

Risk of cracking

Despite the nickel coating, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may shatter into sharp, dangerous pieces.

Allergy Warning

It is widely known that nickel (standard magnet coating) is a common allergen. If your skin reacts to metals, prevent touching magnets with bare hands or opt for versions in plastic housing.

Demagnetization risk

Keep cool. Neodymium magnets are sensitive to temperature. If you need operation above 80°C, look for HT versions (H, SH, UH).

Warning for heart patients

Patients with a pacemaker have to keep an large gap from magnets. The magnetic field can disrupt the operation of the implant.

Crushing risk

Mind your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, destroying anything in their path. Be careful!

Dust explosion hazard

Drilling and cutting of NdFeB material poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.

Precision electronics

Navigation devices and mobile phones are highly sensitive to magnetism. Close proximity with a strong magnet can decalibrate the sensors in your phone.

Choking Hazard

Absolutely store magnets away from children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are fatal.
