Pulling power drops drastically with every mm of spacing. Note that every additional insulation layer (e.g., contamination, varnish, rust) strongly reduces the pull force. Magnetic products operate optimally during direct contact; distance weakens the force. Observe how rapidly the pull force drop, when the product does not touch flatly to the metal substrate. When designing the arrangement, discard unnecessary gaps.

This section defines the approximate shear load required to cause the slippage of the magnet vertically against a upright steel plate (assuming typical friction coefficient). This parameter varies with the air gap between the magnet and the metal.

Table 3: Wall mounting (sliding) - vertical pull
MW 5x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.24 kg / 0.52 LBS 237.0 g / 2.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.16 kg / 0.35 LBS 158.0 g / 1.5 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.08 kg / 0.17 LBS 79.0 g / 0.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.40 kg / 0.87 LBS 395.0 g / 3.9 N

When mounting a holder on a vertical wall (e.g., a board), it will only hold barely about 1/5 of nominal attraction strength. Gravity as well as a low friction coefficient cause that products slide down easier than they pop off the substrate. Designing a hanger? Remember that the sliding force is much weaker than the maximum static pull force. On a slippery surface, the holder will slip down under a noticeably lighter load. Utilizing a rubberized layer can effectively increase the grip.

A thin metal plate cannot conduct the entire magnetic field, which weakens actual performance of the magnet. If you install a neodymium to a thin surface, the flux will pass right through and the holding will be smaller. To squeeze full efficiency of this neodymium's power, you need a suitably thick backing of metal. The saturation phenomenon causes that on sheet metal structures (e.g., thin profiles), the product holds weaker. We recommend selecting the steel cross-section according to the table below.

Standard neodymium magnets irreversibly lose strength after exceeding the maximum temperature. Avoid high temperatures – heat can permanently damage this magnet. With increasing heat, the magnet's power briefly decreases. Refrain from using this magnet near heat sources higher than its operating temperature limit. Ignoring the limit will cause irreversible degradation of magnetic properties.

*Important note: Heat tolerance depends not only on the material grade, as well as the dimension ratios. Flat magnets (pancake types) may lose charge permanently sooner than long magnets. Warning indicator in the table points to permanent field degradation for this specific geometry.

Two magnetic products attract each other from a wider radius than a magnet and sheet combination. Such a system of magnet-to-magnet produces a massive flux and a wider radius of performance. Want to build a solid fastener? Utilize two neodymiums instead of one magnet and a steel. Exercise caution that when attracting two neodymiums, the pinch force is extreme. The levitation is slightly lower than the connection force, but still large.
*The magnetic induction for N-N configuration is approximately ~0 Gs at the midpoint of the gap (due to field cancellation).
Important: Figures refer to friction force of two same neodymium magnets (friction ~0.15 for Ni-Ni coating).

Powerful magnet radiation is a real danger to electronic devices as well as pacemakers. These magnets produce a field that prevents correct functioning of digital equipment. Remember: the invisible magnetic field acts through matter and housings. Increased vigilance must be exercised by people with hearing aids and insulin pumps. Influence will be felt by: automatic timepieces, car keys, membranes, and displays. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

Magnetic elements are delicate – a violent impact against metal can result in shattering. Pay attention to connection velocity – a magnet released freely becomes dangerous. Striking energy can trigger coating fragments or injury to skin. Hold the magnet firmly during installation so it doesn't slam with momentum against the steel surface. A collision at high speed ends with a crack of the magnet. Wear eye protection when playing with powerful specimens.

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

In water, the magnet feels stronger thanks to Archimedes' principle. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Shear force

*Warning: On a vertical wall, the magnet holds just a fraction of its nominal pull.

2. Steel thickness impact

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

3. Thermal stability

*For standard magnets, the safety limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.89

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 offered product is an incredibly powerful cylindrical magnet, composed of modern NdFeB material, which, at dimensions of Ø5x5 mm, guarantees maximum efficiency. This specific item boasts high dimensional repeatability and professional build quality, making it an excellent solution for the most demanding engineers and designers. As a cylindrical magnet with significant force (approx. 0.79 kg), this product is in stock from our warehouse in Poland, ensuring lightning-fast order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is ideal for building electric motors, advanced sensors, and efficient magnetic separators, where maximum induction on a small surface counts. Thanks to the pull force of 7.76 N with a weight of only 0.74 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 professional component. To ensure stability in automation, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.

Magnets N38 are strong enough for 90% of applications in modeling and machine building, where extreme miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø5x5), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.

The presented product is a neodymium magnet with precisely defined parameters: diameter 5 mm and height 5 mm. The key parameter here is the holding force amounting to approximately 0.79 kg (force ~7.76 N), which, with such defined dimensions, proves the high grade of the NdFeB material. 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 5 mm), which means that the N and S poles are located on the flat, circular surfaces. 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 neodymium magnets.

Pros

In addition to their magnetic efficiency, neodymium magnets provide the following advantages:

They do not lose strength, even after around ten years – the drop in power is only ~1% (according to tests),
They are noted for resistance to demagnetization induced by presence of other magnetic fields,
A magnet with a metallic silver surface looks better,
They show high magnetic induction at the operating surface, making them more effective,
Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
Thanks to freedom in constructing and the capacity to customize to client solutions,
Wide application in future technologies – they are commonly used in data components, electric drive systems, diagnostic systems, also complex engineering applications.
Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,

Cons

Disadvantages of neodymium magnets:

Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a special holder, which not only protects them against impacts but also raises their durability
Neodymium magnets decrease their strength 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
Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
We suggest a housing - magnetic mount, due to difficulties in realizing threads inside the magnet and complex shapes.
Health risk related to microscopic parts of magnets can be dangerous, in case of ingestion, which gains importance in the context of child health protection. It is also worth noting that tiny parts of these magnets can complicate diagnosis medical in case of swallowing.
Due to expensive raw materials, their price is relatively high,

Lifting parameters

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

Magnet power was defined for ideal contact conditions, including:

with the use of a sheet made of low-carbon steel, ensuring maximum field concentration
possessing a thickness of min. 10 mm to avoid saturation
characterized by even structure
with total lack of distance (without paint)
for force applied at a right angle (in the magnet axis)
at room temperature

What influences lifting capacity in practice

Effective lifting capacity is influenced by specific conditions, including (from most important):

Gap between surfaces – every millimeter of separation (caused e.g. by varnish or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
Angle of force application – maximum parameter is obtained only during perpendicular pulling. The force required to slide of the magnet along the surface is typically several times lower (approx. 1/5 of the lifting capacity).
Steel thickness – too thin plate does not accept the full field, causing part of the power to be lost into the air.
Chemical composition of the base – low-carbon steel gives the best results. Alloy steels reduce magnetic permeability and holding force.
Base smoothness – the more even the surface, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
Thermal factor – high temperature reduces pulling force. Too high temperature can permanently demagnetize the magnet.

Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate reduces the load capacity.

Safety rules for work with neodymium magnets

Power loss in heat

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

Magnets are brittle

Protect your eyes. Magnets can fracture upon violent connection, ejecting shards into the air. Eye protection is mandatory.

Handling rules

Use magnets consciously. Their huge power can surprise even professionals. Be vigilant and do not underestimate their force.

Dust explosion hazard

Mechanical processing of NdFeB material poses a fire risk. Magnetic powder reacts violently with oxygen and is hard to extinguish.

Bodily injuries

Danger of trauma: The pulling power is so great that it can cause blood blisters, pinching, and broken bones. Use thick gloves.

Electronic devices

Avoid bringing magnets close to a purse, laptop, or TV. The magnetic field can permanently damage these devices and wipe information from cards.

GPS Danger

An intense magnetic field interferes with the operation of magnetometers in phones and navigation systems. Keep magnets near a device to avoid breaking the sensors.

Allergy Warning

Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If skin irritation happens, cease handling magnets and use protective gear.

Adults only

Always store magnets out of reach of children. Choking hazard is significant, and the consequences of magnets connecting inside the body are tragic.

Pacemakers

Medical warning: Neodymium magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.
