Magnetic force weakens significantly per each millimeter of spacing. Keep in mind that even a very thin break (e.g., dirt, varnish, dust) significantly reduces the pull force. Neodymiums operate strongest during direct contact; distance drastically cuts the power. See how quickly the pull force fall, when the magnet does not touch tightly to the steel surface. When planning the assembly, discard redundant distances.

The table below calculates the estimated holding capacity sufficient to start the shifting of the magnet vertically against a vertical metal surface (assuming typical friction). This value varies with the distance between the magnet and the metal.

Table 3: Wall mounting (sliding) - vertical pull
MW 15x4 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	1.27 kg / 2.79 pounds 1266.0 g / 12.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.84 kg / 1.86 pounds 844.0 g / 8.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.42 kg / 0.93 pounds 422.0 g / 4.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	2.11 kg / 4.65 pounds 2110.0 g / 20.7 N

When mounting a holder on a vertical plane (e.g., a car body), it will only hold just approx. 1/5 of its maximum pull force. Gravitational force and a weak degree of grip cause that magnets slip easier than they detach. Planning a hanger? Note that the sliding force is noticeably lower than the maximum static pull force. On a painted metal, the magnet will slip down under a significantly smaller load. Using a rubber layer can significantly increase the grip.

12 mm	100%	4.22 kg / 9.30 pounds 4220.0 g / 41.4 N

A thin sheet cannot conduct the entire magnetic field, which squanders power of the holder. Should you attach a powerful product to a weak sheet, the field will pass right through and the holding will be smaller. To squeeze full efficiency of this magnet's potential, you need a suitably thick backing of metal. The material oversaturation causes that on delicate walls (e.g., thin profiles), the magnet holds weaker. We advise picking the steel dimension from these parameters.

Classic neodymiums change their properties strength after exceeding the maximum temperature. Watch out for overheating – high temperature can irreversibly damage this product. With every degree above norm, the neodymium's capacity temporarily decreases. Avoid using this magnet close to ovens exceeding its safe range. Ignoring the limit will lead to irreversible degradation of magnetism.

*Technical advisory: Thermal stability depends not only on the material grade, as well as the dimension ratios. Thin magnets (low permeance coefficient) are more susceptible to demagnetization under lower heat stress than taller cylinders. Red status in the table indicates a risk of irreversible loss for this particular item.

Two magnets interact from a much further distance than a neodymium and metal combination. The connection of two magnets creates a more powerful interaction and a wider radius of performance. Planning to create a strong closure? Apply two magnets instead of a neodymium and a striker plate. Exercise caution that when bringing together two magnets, the collision energy is huge. The levitation is marginally weaker than the attraction, but still significant.
*Flux density for N-N configuration reaches ~0 Gs at the geometric center between the magnets (due to field cancellation).
Attention: Estimates demonstrate friction force of a pair of matching magnets (friction coefficient ~0.15 for Ni-Ni layer).

Powerful magnet radiation poses a real danger to electronics as well as pacemakers. These magnets produce a field that disrupts operation of sensitive medical devices. Be aware: the invisible magnetic field penetrates the body and plastic. Exceptional care must be exercised by people with cochlear implants and insulin pumps. Influence will be felt by: mechanical watches, car keys, speakers, and displays. Do not bring the product near payment cards, HDD media, or precise measuring instruments.

NdFeB products are delicate – a strong collision with metal risks their cracking. Pay attention to connection velocity – a magnet released freely turns into a projectile. Striking energy can trigger coating fragments or painful pinches to skin. 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 ends with a crack of the magnet. Use safety goggles when handling 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. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Wall mount (shear)

*Warning: On a vertical surface, the magnet retains only a fraction of its nominal pull.

2. Efficiency vs thickness

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

3. Temperature resistance

*For N38 material, the safety limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.37

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.

This product is an incredibly powerful cylindrical magnet, produced from advanced NdFeB material, which, at dimensions of Ø15x4 mm, guarantees the highest energy density. This specific item features an accuracy of ±0.1mm and industrial build quality, making it an excellent solution for the most demanding engineers and designers. As a cylindrical magnet with impressive force (approx. 4.22 kg), this product is in stock from our warehouse in Poland, ensuring lightning-fast order fulfillment. Furthermore, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

It finds application in DIY projects, advanced automation, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 41.38 N with a weight of only 5.3 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 long-term durability in automation, anaerobic resins 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 (Ø15x4), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

This model is characterized by dimensions Ø15x4 mm, which, at a weight of 5.3 g, makes it an element with impressive magnetic energy density. The key parameter here is the holding force amounting to approximately 4.22 kg (force ~41.38 N), which, with such defined dimensions, proves the high power of the NdFeB material. The product has a [NiCuNi] coating, which secures it 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 15 mm. 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 through the diameter if your project requires it.

Pros and cons of rare earth magnets.

Pros

Besides their immense pulling force, neodymium magnets offer the following advantages:

They retain magnetic properties for around 10 years – the drop is just ~1% (according to analyses),
Magnets very well defend themselves against demagnetization caused by ambient magnetic noise,
The use of an metallic layer of noble metals (nickel, gold, silver) causes the element to have aesthetics,
Magnets exhibit exceptionally strong magnetic induction on the surface,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
Possibility of exact forming and modifying to atypical requirements,
Wide application in high-tech industry – they find application in HDD drives, brushless drives, diagnostic systems, as well as multitasking production systems.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which allows their use in small systems

Limitations

Characteristics of disadvantages of neodymium magnets: application proposals

To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
They oxidize in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
Due to limitations in realizing nuts and complicated shapes in magnets, we propose using a housing - magnetic holder.
Health risk to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child health protection. It is also worth noting that small components of these products can complicate diagnosis medical when they are in the body.
Due to neodymium price, their price is higher than average,

Lifting parameters

Maximum holding power of the magnet – what contributes to it?

The specified lifting capacity refers to the maximum value, measured under laboratory conditions, specifically:

on a block made of mild steel, effectively closing the magnetic flux
with a cross-section minimum 10 mm
characterized by even structure
under conditions of no distance (metal-to-metal)
for force applied at a right angle (pull-off, not shear)
in neutral thermal conditions

Magnet lifting force in use – key factors

Holding efficiency is affected by specific conditions, including (from most important):

Distance – the presence of any layer (rust, dirt, gap) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
Loading method – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet holds much less (typically approx. 20-30% of nominal force).
Metal thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
Steel grade – the best choice is high-permeability steel. Stainless steels may have worse magnetic properties.
Surface finish – ideal contact is obtained only on polished steel. Rough texture create air cushions, weakening the magnet.
Thermal factor – hot environment reduces magnetic field. Too high temperature can permanently damage the magnet.

Lifting capacity was determined by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, whereas under parallel forces the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate decreases the lifting capacity.

Precautions when working with neodymium magnets

Protect data

Data protection: Strong magnets can ruin data carriers and sensitive devices (heart implants, medical aids, timepieces).

Metal Allergy

A percentage of the population suffer from a sensitization to Ni, which is the common plating for neodymium magnets. Prolonged contact can result in an allergic reaction. We recommend use protective gloves.

GPS Danger

A strong magnetic field interferes with the functioning of magnetometers in phones and navigation systems. Maintain magnets near a smartphone to prevent damaging the sensors.

Thermal limits

Regular neodymium magnets (grade N) undergo demagnetization when the temperature surpasses 80°C. Damage is permanent.

Conscious usage

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

Swallowing risk

Always keep magnets away from children. Choking hazard is high, and the effects of magnets clamping inside the body are tragic.

Fragile material

NdFeB magnets are sintered ceramics, meaning they are fragile like glass. Clashing of two magnets will cause them breaking into small pieces.

Pacemakers

Medical warning: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have electronic implants.

Dust is flammable

Dust created during grinding of magnets is flammable. Do not drill into magnets unless you are an expert.

Physical harm

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