Magnetic force weakens sharply with every mm of gap. Note that even a microscopic distance (e.g., contamination, varnish, rust) strongly weakens the grip. Magnetic products hold most effectively at the point of direct contact; air break nullifies the force. Observe how rapidly the load capacity drop, when the product does not touch directly to the steel surface. When designing the mounting, discard unnecessary gaps.

Table 2: Vertical hold (wall)

This section presents the estimated force needed to initiate the sliding of the magnet downwards along a upright metal surface (considering typical friction coefficient). The holding force depends on the gap size between the magnet and the metal.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MW 5x30 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.14 kg / 135.0 g 1.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.09 kg / 90.0 g 0.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.05 kg / 45.0 g 0.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.23 kg / 225.0 g 2.2 N

When mounting a element on a upright plane (e.g., a car body), it you can count on just approx. 1/5 of its maximum pull force. Gravity and a low friction coefficient mean that products slip faster than they pop off the substrate. Planning a wall mount? Consider that the sliding force is much weaker than the perpendicular breakaway force. On a smooth steel, the magnet will slip down under a noticeably lighter load. Application of an anti-slip pad can drastically improve the result.

Table 4: Steel thickness (substrate influence) - sheet metal selection
MW 5x30 / N38

Steel thickness (mm)	% power	Real pull force (kg)
0.5 mm	10%	0.05 kg / 45.0 g 0.4 N
1 mm	25%	0.11 kg / 112.5 g 1.1 N
2 mm	50%	0.23 kg / 225.0 g 2.2 N
5 mm	100%	0.45 kg / 450.0 g 4.4 N
10 mm	100%	0.45 kg / 450.0 g 4.4 N

A thin sheet is not enough to conduct the full magnetic flux, which wastes potential of the magnet. Should you mount a strong magnet to a thin surface, the magnetism will pass right through and the pull force will drop sharply. To utilize the maximum of this neodymium's power, you require a sufficiently solid element of metal. The saturation phenomenon causes that on sheet metal structures (e.g., thin profiles), the magnet shows lower pull force. We suggest choosing the steel thickness according to the table below.

Table 5: Thermal resistance (stability) - power drop

20 °C	0.0%	0.45 kg / 450.0 g 4.4 N	OK

60 °C	-4.4%	0.43 kg / 430.2 g 4.2 N	OK
80 °C	-6.6%	0.42 kg / 420.3 g 4.1 N
100 °C	-28.8%	0.32 kg / 320.4 g 3.1 N

Standard neodymium magnets irreversibly lose power above the temperature limit. Watch out for overheating – heat can irreversibly damage this magnet. With every degree above norm, the neodymium's capacity momentarily drops. Do not use this product near heat sources higher than its safe range. Exceeding the critical threshold will result in permanent loss of magnetic properties.

*Technical advisory: Thermal stability depends not only on the material grade, and the Permeance Coefficient Pc. Flat magnets (pancake types) are more susceptible to demagnetization under lower heat stress than long magnets. The danger warning in the table points to a risk of irreversible loss for this specific geometry.

Two magnets interact from a wider radius than a neodymium and metal combination. Such a system of two magnets generates a stronger field and a larger range of action. Planning to create a powerful holder? Use a pair of magnets instead of a neodymium and a striker plate. Remember that when attracting two neodymiums, the collision energy is huge. The levitation is a bit weaker than the connection force, but still large.
*Field value between like poles drops to ~0 Gs at the midpoint of the gap (caused by magnetic field nullification).

Powerful magnet radiation is a serious hazard to electronics and medical implants. These NdFeB products generate a flux that disrupts operation of digital equipment. Be aware: the unseen radiation acts through matter and housings. Special caution must be exercised by people with cochlear implants and drug dispensers. Also at risk are: mechanical watches, remotes, membranes, and screens. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Neodymium magnets are very brittle – a strong collision with metal risks their cracking. Watch the impact speed – a neodymium left loose turns into a projectile. Striking energy can cause material chips or painful pinches to fingers. Hold the magnet firmly during bringing near metal so it doesn't slam with momentum against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction 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!

Contrary to myths, water does not block the magnetic field. Buoyancy helps in lifting finds.

1. Sliding resistance

*Warning: On a vertical wall, the magnet holds only a fraction of its max power.

2. Steel saturation

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

3. Heat tolerance

*For N38 grade, 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) = 1.59

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 exceptionally strong cylindrical magnet, made from durable NdFeB material, which, with dimensions of Ø5x30 mm, guarantees optimal power. The MW 5x30 / N38 component boasts high dimensional repeatability and professional build quality, making it a perfect solution for professional engineers and designers. As a magnetic rod with significant force (approx. 0.45 kg), this product is available off-the-shelf from our European logistics center, ensuring rapid order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.

It successfully proves itself in modeling, advanced robotics, and broadly understood industry, serving as a fastening or actuating element. Thanks to the high power of 4.40 N with a weight of only 4.42 g, this rod is indispensable in miniature devices and wherever low weight is crucial.

Due to the brittleness of the NdFeB material, we absolutely advise against force-fitting (so-called press-fit), as this risks immediate cracking of this professional component. To ensure stability in industry, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.

Magnets NdFeB grade N38 are suitable for the majority of applications in modeling and machine building, where excessive miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø5x30), 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 Ø5x30 mm, which, at a weight of 4.42 g, makes it an element with impressive magnetic energy density. The key parameter here is the lifting capacity amounting to approximately 0.45 kg (force ~4.40 N), which, with such compact dimensions, proves the high power of the NdFeB material. The product has a [NiCuNi] coating, which protects the surface 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 5 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.

Strengths as well as weaknesses of Nd₂Fe₁₄B magnets.

Advantages

Besides their magnetic performance, neodymium magnets are valued for these benefits:

They have constant strength, and over nearly 10 years their attraction force decreases symbolically – ~1% (in testing),
They retain their magnetic properties even under strong external field,
A magnet with a smooth gold surface is more attractive,
The surface of neodymium magnets generates a maximum magnetic field – this is one of their assets,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
Due to the possibility of flexible forming and adaptation to custom projects, neodymium magnets can be created in a variety of geometric configurations, which makes them more universal,
Fundamental importance in electronics industry – they are utilized in HDD drives, electric drive systems, medical devices, also industrial machines.
Thanks to concentrated force, small magnets offer high operating force, in miniature format,

Cons

What to avoid - cons of neodymium magnets: tips and applications.

To avoid cracks under impact, we recommend using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
We recommend cover - magnetic holder, due to difficulties in realizing threads inside the magnet and complicated forms.
Possible danger resulting from small fragments of magnets are risky, in case of ingestion, which gains importance in the context of child health protection. Furthermore, small elements of these magnets are able to disrupt the diagnostic process medical after entering the body.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Holding force characteristics

Maximum lifting capacity of the magnet – what it depends on?

The specified lifting capacity represents the limit force, recorded under optimal environment, meaning:

on a plate made of structural steel, effectively closing the magnetic flux
possessing a thickness of minimum 10 mm to ensure full flux closure
with a plane free of scratches
without any insulating layer between the magnet and steel
under vertical application of breakaway force (90-degree angle)
at temperature room level

Impact of factors on magnetic holding capacity in practice

Real force is affected by specific conditions, mainly (from priority):

Clearance – the presence of any layer (paint, dirt, gap) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
Loading method – catalog parameter refers to detachment vertically. When attempting to slide, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
Plate thickness – too thin plate causes magnetic saturation, causing part of the power to be wasted to the other side.
Steel type – low-carbon steel gives the best results. Alloy steels decrease magnetic permeability and holding force.
Plate texture – smooth surfaces ensure maximum contact, which improves field saturation. Rough surfaces weaken the grip.
Temperature influence – high temperature reduces magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.

Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the holding force is lower. In addition, even a minimal clearance between the magnet and the plate lowers the lifting capacity.

Safe handling of neodymium magnets

Risk of cracking

Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.

Safe operation

Use magnets with awareness. Their powerful strength can shock even experienced users. Stay alert and respect their force.

Maximum temperature

Monitor thermal conditions. Exposing the magnet to high heat will ruin its magnetic structure and pulling force.

GPS Danger

An intense magnetic field interferes with the functioning of compasses in smartphones and navigation systems. Keep magnets near a device to avoid damaging the sensors.

Safe distance

Powerful magnetic fields can corrupt files on credit cards, hard drives, and other magnetic media. Maintain a gap of at least 10 cm.

Do not drill into magnets

Drilling and cutting of neodymium magnets poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.

Pacemakers

Health Alert: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.

Swallowing risk

Neodymium magnets are not toys. Accidental ingestion of a few magnets may result in them pinching intestinal walls, which constitutes a direct threat to life and requires urgent medical intervention.

Crushing force

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

Sensitization to coating

Some people have a sensitization to nickel, which is the typical protective layer for neodymium magnets. Prolonged contact may cause a rash. We strongly advise use safety gloves.
