Magnetic force weakens drastically per each millimeter of gap. Remember that even a very thin break (e.g., contamination, varnish, dust) significantly diminishes the holding power. Magnets work optimally during direct contact; air break kills the power. See how rapidly the pull force plummet, when the product does not touch flatly to the metal substrate. When planning the assembly, avoid unnecessary gaps.

50 mm	Stal (~0.2)	0.00 kg / 0.00 pounds 0.0 g / 0.0 N

The table below indicates the approximate weight limit needed to initiate the sliding of the magnet vertically on a vertical metal surface (assuming standard friction coefficient). This parameter varies with the separation distance between the magnet and the metal.

Table 3: Wall mounting (shearing) - behavior on slippery surfaces
MW 8x1.5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.22 kg / 0.49 pounds 222.0 g / 2.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.15 kg / 0.33 pounds 148.0 g / 1.5 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.07 kg / 0.16 pounds 74.0 g / 0.7 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.37 kg / 0.82 pounds 370.0 g / 3.6 N

When mounting a holder on a vertical surface (e.g., a fridge), it will maintain just approx. 20%-30% of its nominal power. Gravitational force and a weak degree of grip mean that magnets slide down faster than they pull off. Want to create a hanger? Note that the shear force is much weaker than the maximum static pull force. On a slippery surface, the magnet will slip down under a significantly smaller cargo. Using a rubber pad can drastically improve the result.

Table 4: Steel thickness (saturation) - sheet metal selection
MW 8x1.5 / N38

Steel thickness (mm)	% power	Real pull force (kg/lbs/g/N)
0.5 mm	10%	0.07 kg / 0.16 pounds 74.0 g / 0.7 N
1 mm	25%	0.19 kg / 0.41 pounds 185.0 g / 1.8 N
2 mm	50%	0.37 kg / 0.82 pounds 370.0 g / 3.6 N
3 mm	75%	0.55 kg / 1.22 pounds 555.0 g / 5.4 N
5 mm	100%	0.74 kg / 1.63 pounds 740.0 g / 7.3 N
10 mm	100%	0.74 kg / 1.63 pounds 740.0 g / 7.3 N
11 mm	100%	0.74 kg / 1.63 pounds 740.0 g / 7.3 N
12 mm	100%	0.74 kg / 1.63 pounds 740.0 g / 7.3 N

A thin metal plate is incapable of take in the entire magnetic field, which weakens actual performance of the magnet. If you attach a powerful product to a weak sheet, the magnetism will penetrate right through and the holding will be smaller. To utilize 100% of this neodymium's power, you need a suitably thick piece of metal. The saturation phenomenon causes that on thin elements (e.g., appliance housings), the magnet shows lower pull force. We recommend selecting the steel dimension from these parameters.

Table 5: Thermal resistance (material behavior) - thermal limit
MW 8x1.5 / N38

Ambient temp. (°C)	Power loss	Remaining pull (kg/lbs/g/N)	Status

40 °C	-2.2%	0.72 kg / 1.60 pounds 723.7 g / 7.1 N	OK

100 °C	-28.8%	0.53 kg / 1.16 pounds 526.9 g / 5.2 N

Standard neodymium magnets change their properties strength past the thermal threshold. Avoid high temperatures – heat can permanently destroy this product. As the temperature rises, the neodymium's force temporarily lowers. Do not use this magnet close to ovens exceeding its working range. Ignoring the limit will lead to destruction of magnetic properties.

*Technical advisory: Temperature resistance depends not only on the material grade, and the Permeance Coefficient Pc. Flat magnets (low Pc) risk losing magnetic properties sooner compared to rod magnets. Red status in the table points to permanent field degradation for this particular item.

Two magnetic products interact from a wider radius than a magnet and steel combination. The setup of two magnets generates a stronger field and a wider radius of action. Planning to create a powerful holder? Apply two magnets instead of one magnet and a steel. Remember that when attracting two neodymiums, the pinch force is massive. The repulsion force is slightly lower than the connection force, but still large.
*Field value between like poles is approximately ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
* Results apply to friction force of two identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni plating).

A strong magnetic field is a real danger to electronics as well as medical implants. These NdFeB products produce a flux that prevents correct functioning of sensitive medical devices. Remember: the invisible magnetic field acts through matter and glass. Special caution must be exercised by people with cochlear implants and insulin pumps. Influence will be felt by: mechanical watches, car keys, membranes, and displays. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Table 8: Dynamics (kinetic energy) - collision effects
MW 8x1.5 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	36.39 km/h (10.11 m/s)	0.03 J
30 mm	62.94 km/h (17.48 m/s)	0.09 J
50 mm	81.25 km/h (22.57 m/s)	0.15 J
100 mm	114.91 km/h (31.92 m/s)	0.29 J

NdFeB products are prone to chipping – a collision with steel risks their cracking. Pay attention to connection velocity – a magnet released freely turns into a projectile. Striking energy can destroy the magnet or painful pinches to skin. Hold the magnet firmly during installation so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Use safety goggles when working with large magnets.

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

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

1. Wall mount (shear)

*Note: On a vertical surface, the magnet holds just a fraction of its perpendicular strength.

2. Steel thickness impact

*Thin metal sheet (e.g. computer case) significantly limits the holding force.

3. Thermal stability

*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) = 0.27

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.

MW 35x5 / N38 - cylindrical magnet

13.81 ZŁ brutto / pcs

This product is a very strong cylindrical magnet, composed of modern NdFeB material, which, at dimensions of Ø8x1.5 mm, guarantees the highest energy density. The MW 8x1.5 / N38 component is characterized by high dimensional repeatability and professional build quality, making it a perfect solution for the most demanding engineers and designers. As a cylindrical magnet with significant force (approx. 0.74 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring rapid order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

It successfully proves itself in DIY projects, advanced robotics, and broadly understood industry, serving as a positioning or actuating element. Thanks to the pull force of 7.27 N with a weight of only 0.57 g, this cylindrical magnet is indispensable in miniature devices and wherever every gram matters.

Since our magnets have a very precise dimensions, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 8.1 mm) using epoxy glues. 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.

Grade N38 is the most popular standard for industrial neodymium magnets, offering a great economic balance and high resistance to demagnetization. If you need even stronger magnets in the same volume (Ø8x1.5), 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 8 mm and height 1.5 mm. The value of 7.27 N means that the magnet is capable of holding a weight many times exceeding its own mass of 0.57 g. The product has a [NiCuNi] coating, which secures it against oxidation, giving it an aesthetic, silvery shine.

This rod magnet is magnetized axially (along the height of 1.5 mm), which means that the N and S poles are located on the flat, circular surfaces. Such an arrangement is most desirable 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.

Advantages and disadvantages of rare earth magnets.

Pros

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

They retain magnetic properties for around 10 years – the drop is just ~1% (in theory),
They do not lose their magnetic properties even under strong external field,
In other words, due to the reflective finish of gold, the element looks attractive,
Magnets possess huge magnetic induction on the outer side,
Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
Thanks to freedom in constructing and the ability to customize to specific needs,
Huge importance in modern industrial fields – they serve a role in hard drives, electric drive systems, medical devices, and technologically advanced constructions.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which allows their use in miniature devices

Disadvantages

Disadvantages of neodymium magnets:

At very strong impacts they can crack, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
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 durability even at temperatures up to 230°C
Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
Limited possibility of creating nuts in the magnet and complicated shapes - recommended is a housing - mounting mechanism.
Potential hazard resulting from small fragments of magnets are risky, when accidentally swallowed, which is particularly important in the context of child health protection. Additionally, small components of these products are able to complicate diagnosis medical after entering the body.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Lifting parameters

Best holding force of the magnet in ideal parameters – what contributes to it?

Breakaway force is the result of a measurement for the most favorable conditions, assuming:

on a plate made of mild steel, effectively closing the magnetic field
with a cross-section no less than 10 mm
characterized by smoothness
under conditions of gap-free contact (surface-to-surface)
during detachment in a direction perpendicular to the plane
at ambient temperature approx. 20 degrees Celsius

Determinants of practical lifting force of a magnet

Real force impacted by specific conditions, including (from priority):

Gap (between the magnet and the metal), since even a very small distance (e.g. 0.5 mm) leads to a drastic drop in force by up to 50% (this also applies to paint, corrosion or debris).
Loading method – catalog parameter refers to detachment vertically. When applying parallel force, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
Plate thickness – insufficiently thick steel causes magnetic saturation, causing part of the flux to be escaped to the other side.
Material composition – not every steel reacts the same. Alloy additives worsen the attraction effect.
Surface finish – full contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
Temperature influence – high temperature reduces magnetic field. Too high temperature can permanently damage the magnet.

Lifting capacity testing was conducted on a smooth plate of suitable thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the load capacity is reduced by as much as 5 times. In addition, even a slight gap between the magnet and the plate lowers the load capacity.

Precautions when working with NdFeB magnets

Flammability

Powder produced during grinding of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.

Keep away from computers

Powerful magnetic fields can corrupt files on payment cards, hard drives, and other magnetic media. Stay away of at least 10 cm.

Do not underestimate power

Use magnets with awareness. Their powerful strength can surprise even professionals. Be vigilant and respect their force.

Sensitization to coating

Nickel alert: The Ni-Cu-Ni coating consists of nickel. If skin irritation occurs, immediately stop handling magnets and wear gloves.

Pinching danger

Risk of injury: The pulling power is so immense that it can cause blood blisters, pinching, and even bone fractures. Use thick gloves.

Permanent damage

Regular neodymium magnets (N-type) lose power when the temperature exceeds 80°C. The loss of strength is permanent.

Shattering risk

Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.

Do not give to children

Always store magnets out of reach of children. Ingestion danger is high, and the effects of magnets connecting inside the body are tragic.

Health Danger

Warning for patients: Strong magnetic fields affect medical devices. Keep minimum 30 cm distance or request help to handle the magnets.

Threat to navigation

Be aware: neodymium magnets produce a field that interferes with precision electronics. Keep a safe distance from your phone, device, and GPS.
