Magnetic force weakens significantly with every mm of distance. Keep in mind that every additional insulation layer (e.g., contamination, paint, dust) significantly weakens the grip. Neodymiums work most effectively in perfect adhesion; air break weakens the force. See how flashily the load capacity plummet, when the product does not touch directly to the steel surface. When calculating the mounting, avoid redundant distances.

This section shows the approximate weight limit needed to cause the shifting of the magnet vertically against a upright metal surface (assuming typical friction coefficient). This parameter varies with the air gap between the magnet and the surface.

Table 3: Wall mounting (sliding) - vertical pull

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	64.55 kg / 142.31 pounds 64551.0 g / 633.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	43.03 kg / 94.87 pounds 43034.0 g / 422.2 N

When mounting a holder on a vertical wall (e.g., a car body), it you can count on just about 1/5 of nominal attraction strength. Gravitational force and a weak degree of grip mean that magnets move down easier than they pop off the substrate. Designing a hanger? Consider that the sliding force is much weaker than the maximum static pull force. On a smooth steel, the holder will slide down under a much lighter weight. Using a rubber pad can drastically increase the grip.

A too thin steel cannot absorb the full magnetic flux, which wastes potential of the magnet. Should you install a neodymium to a weak sheet, the flux will penetrate right through and the holding will be smaller. To utilize full efficiency of this magnet's potential, you require a sufficiently solid piece of metal. The saturation effect means that on sheet metal structures (e.g., thin profiles), the product works worse. We suggest choosing the steel thickness according to the table below.

Standard neodymium magnets irreversibly lose power after exceeding the maximum temperature. Watch out for overheating – excessive heat can irreversibly destroy this magnet. With every degree above norm, the magnet's force momentarily drops. Avoid using this product near heat sources exceeding its safe range. Too high temperature will cause permanent loss of magnetism.

*Technical advisory: Thermal stability depends not only on the material grade, and the Permeance Coefficient Pc. Flat magnets (low permeance coefficient) risk losing magnetic properties at lower temperatures than taller cylinders. Warning indicator in the table indicates a risk of irreversible loss for this particular item.

Two strong neodymiums interact from a wider radius than a magnet and steel setup. The setup of two magnets generates a stronger field and a further horizon of operation. Designing a solid fastener? Utilize two neodymiums instead of a neodymium and a striker plate. Be careful that when bringing together two magnets, the impact force is huge. The levitation is marginally weaker than the attraction, but still large.
*Flux density in repulsion mode reaches ~0 Gs at the midpoint of the gap (resulting from vector opposition).
* Figures show sliding force of dual identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

Table 7: Hazards (electronics) - precautionary measures
MW 100x30 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	44.0 cm
Hearing aid	10 Gs (1.0 mT)	34.5 cm
Timepiece	20 Gs (2.0 mT)	27.0 cm
Mobile device	40 Gs (4.0 mT)	21.0 cm

Payment card	400 Gs (40.0 mT)	8.0 cm
HDD hard drive	600 Gs (60.0 mT)	6.5 cm

Powerful magnet radiation is a real danger to IT equipment and pacemakers. These NdFeB products generate a field that prevents correct functioning of sensitive medical devices. Notice: the invisible magnetic field passes through tissues and glass. Exceptional care must be exercised by people with cochlear implants and drug dispensers. The risk also applies to: automatic timepieces, car keys, membranes, and displays. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Table 8: Collisions (cracking risk) - warning
MW 100x30 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	15.21 km/h (4.22 m/s)	15.77 J
30 mm	22.01 km/h (6.11 m/s)	33.03 J
50 mm	26.02 km/h (7.23 m/s)	46.17 J
100 mm	35.32 km/h (9.81 m/s)	85.04 J

NdFeB products are very brittle – a strong collision with metal causes immediate chipping. Control the attraction moment – a magnet released freely becomes dangerous. Striking energy can trigger coating fragments or dangerous crushing to skin. Always hold the magnet during bringing near metal so it doesn't hit violently against the steel surface. A contact at a velocity of dozens of km/h ends with a crack of the neodymium. Use safety goggles when playing with large magnets.

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

In water, the magnet feels stronger thanks to Archimedes' principle. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Sliding resistance

*Warning: On a vertical wall, the magnet retains merely ~20% of its nominal pull.

2. Steel saturation

*Thin metal sheet (e.g. computer case) severely reduces 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) = 0.40

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 presented product is an extremely powerful cylindrical magnet, produced from modern NdFeB material, which, at dimensions of Ø100x30 mm, guarantees maximum efficiency. The MW 100x30 / N38 model boasts an accuracy of ±0.1mm and industrial build quality, making it an excellent solution for the most demanding engineers and designers. As a magnetic rod with impressive force (approx. 215.17 kg), this product is available off-the-shelf from our European logistics center, ensuring lightning-fast order fulfillment. Furthermore, its Ni-Cu-Ni coating effectively protects it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

It successfully proves itself in modeling, advanced robotics, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 2110.78 N with a weight of only 1767.15 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., 100.1 mm) using two-component epoxy glues. To ensure long-term durability in industry, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.

Magnets N38 are strong enough for the majority of applications in automation and machine building, where excessive miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø100x30), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.

The presented product is a neodymium magnet with precisely defined parameters: diameter 100 mm and height 30 mm. The value of 2110.78 N means that the magnet is capable of holding a weight many times exceeding its own mass of 1767.15 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 100 mm. 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 through the diameter if your project requires it.

Pros and cons of neodymium magnets.

Benefits

Besides their high retention, neodymium magnets are valued for these benefits:

Their power remains stable, and after approximately ten years it drops only by ~1% (according to research),
They are resistant to demagnetization induced by external field influence,
In other words, due to the reflective layer of gold, the element gains a professional look,
They feature high magnetic induction at the operating surface, which increases their power,
Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures approaching 230°C and above...
Thanks to versatility in forming and the capacity to modify to specific needs,
Key role in high-tech industry – they find application in data components, drive modules, advanced medical instruments, also multitasking production systems.
Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,

Weaknesses

Disadvantages of neodymium magnets:

They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (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 very resistant to heat
Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
We suggest a housing - magnetic mount, due to difficulties in producing nuts inside the magnet and complicated shapes.
Possible danger resulting from small fragments of magnets are risky, when accidentally swallowed, which becomes key in the context of child safety. Additionally, tiny parts of these devices can disrupt the diagnostic process medical after entering the body.
Due to neodymium price, their price is higher than average,

Holding force characteristics

Highest magnetic holding force – what contributes to it?

The specified lifting capacity represents the peak performance, obtained under laboratory conditions, specifically:

on a plate made of structural steel, effectively closing the magnetic flux
with a cross-section of at least 10 mm
with a surface free of scratches
with total lack of distance (without impurities)
during pulling in a direction perpendicular to the mounting surface
in temp. approx. 20°C

Practical lifting capacity: influencing factors

Effective lifting capacity impacted by working environment parameters, including (from most important):

Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by veneer or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
Loading method – declared lifting capacity refers to detachment vertically. When slipping, the magnet exhibits much less (typically approx. 20-30% of nominal force).
Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
Steel grade – ideal substrate is high-permeability steel. Cast iron may attract less.
Surface finish – ideal contact is obtained only on smooth steel. Rough texture create air cushions, reducing force.
Temperature – heating the magnet results in weakening of force. It is worth remembering the thermal limit for a given model.

Lifting capacity was assessed by applying a steel plate with a smooth surface of suitable thickness (min. 20 mm), under vertically applied force, whereas under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate decreases the holding force.

Safety rules for work with neodymium magnets

Implant safety

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

Adults only

Only for adults. Tiny parts can be swallowed, causing serious injuries. Keep away from kids and pets.

Dust explosion hazard

Mechanical processing of neodymium magnets carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.

Electronic hazard

Avoid bringing magnets close to a purse, laptop, or TV. The magnetism can destroy these devices and wipe information from cards.

Crushing risk

Pinching hazard: The attraction force is so immense that it can result in hematomas, crushing, and even bone fractures. Use thick gloves.

Shattering risk

Despite metallic appearance, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.

Nickel coating and allergies

Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If an allergic reaction appears, cease handling magnets and wear gloves.

Caution required

Handle magnets with awareness. Their huge power can shock even experienced users. Be vigilant and do not underestimate their force.

Permanent damage

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

Phone sensors

Remember: neodymium magnets generate a field that disrupts sensitive sensors. Maintain a separation from your mobile, device, and navigation systems.
