Pulling power decreases significantly with every subsequent millimeter of spacing. Remember that even a very thin break (e.g., dirt, paint, dust) significantly reduces the pull force. Magnetic products work strongest in perfect adhesion; gap nullifies the power. See how flashily the parameters fall, when the magnet does not adhere flatly to the metal substrate. When designing the arrangement, discard redundant distances.

This section presents the approximate shear load sufficient to start the downward movement of the magnet down along a vertical steel wall (assuming standard friction coefficient). The holding force varies with the distance between the magnet and the metal.

Table 3: Vertical assembly (shearing) - vertical pull
MW 3x1 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.06 kg / 0.14 pounds 63.0 g / 0.6 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.04 kg / 0.09 pounds 42.0 g / 0.4 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.02 kg / 0.05 pounds 21.0 g / 0.2 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.11 kg / 0.23 pounds 105.0 g / 1.0 N

When mounting a element on a vertical wall (e.g., a fridge), it you can count on barely about 20%-30% of its nominal power. Gravitational force as well as a low friction coefficient mean that magnets slip faster than they pull off. Planning a vertical fastening? Consider that the sliding force is much weaker than the maximum static pull force. On a slippery surface, the magnet will slip down under a much lighter cargo. Using a rubber pad can drastically raise the stability.

12 mm	100%	0.21 kg / 0.46 pounds 210.0 g / 2.1 N

A thin sheet cannot conduct the full magnetic flux, which weakens actual performance of the holder. Should you install a neodymium to a weak sheet, the field will penetrate right through and the attraction force will be weaker. To utilize 100% of this neodymium's power, you need a suitably thick backing of metal. The saturation phenomenon means that on sheet metal structures (e.g., appliance housings), the product works worse. We advise picking the steel thickness from these parameters.

Ordinary NdFeB products lose parameters past the thermal threshold. Avoid high temperatures – excessive heat can permanently demagnetize this product. With increasing heat, the magnet's power briefly decreases. Refrain from using this product close to ovens higher than its working range. Ignoring the limit will result in destruction of magnetism.

*Technical advisory: Temperature resistance 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. The danger warning in the table signals a risk of irreversible loss for this specific geometry.

Two strong neodymiums interact from a much further distance than a magnet and steel combination. Such a system of two magnets produces a massive flux and a further horizon of performance. Designing a solid fastener? Use a pair of 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 slightly lower than the connection force, but still significant.
*Field value between like poles drops to ~0 Gs in the exact middle between the magnets (due to field cancellation).
Important: Figures show shear force of two matching magnets (friction ~0.15 for Ni-Ni coating).

Powerful magnet radiation is a real danger to IT equipment and pacemakers. These NdFeB products generate a flux that destroys function of sensitive medical devices. Notice: the invisible magnetic field penetrates the body and plastic. Special caution must be exercised by people with cochlear implants and insulin pumps. The risk also applies to: mechanical watches, remotes, membranes, and displays. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Table 8: Dynamics (cracking risk) - collision effects

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	65.36 km/h (18.16 m/s)	0.01 J

100 mm	206.68 km/h (57.41 m/s)	0.08 J

Neodymium magnets are delicate – a collision with steel can result in shattering. Watch the impact speed – a neodymium left loose turns into a projectile. Kinetic force can destroy the magnet or dangerous crushing to fingers. Hold the magnet firmly during bringing near metal so it doesn't slam with momentum against the metal. A collision at high speed ends with a crack of the neodymium. Wear safety glasses when working with powerful specimens.

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

Water displaces steel, making heavy objects slightly lighter. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Shear force

*Caution: On a vertical wall, the magnet holds only a fraction of its perpendicular strength.

2. Steel saturation

*Thin steel (e.g. 0.5mm PC case) significantly limits the holding force.

3. Thermal stability

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.44

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 15x4 / N38 - cylindrical magnet

1.968 ZŁ brutto / pcs

This product is an exceptionally strong cylindrical magnet, produced from durable NdFeB material, which, with dimensions of Ø3x1 mm, guarantees optimal power. The MW 3x1 / N38 component is characterized by an accuracy of ±0.1mm and professional build quality, making it a perfect solution for the most demanding engineers and designers. As a magnetic rod with impressive force (approx. 0.21 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 typical operating conditions, ensuring an aesthetic appearance and durability for years.

It successfully proves itself in DIY projects, advanced automation, and broadly understood industry, serving as a fastening or actuating element. Thanks to the high power of 2.10 N with a weight of only 0.05 g, this cylindrical magnet is indispensable in miniature devices and wherever low weight is crucial.

Due to the delicate structure of the ceramic sinter, we absolutely advise against 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 do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.

Grade N38 is the most popular standard for industrial neodymium magnets, offering an optimal price-to-power ratio and operational stability. If you need the strongest magnets in the same volume (Ø3x1), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.

This model is characterized by dimensions Ø3x1 mm, which, at a weight of 0.05 g, makes it an element with impressive magnetic energy density. The value of 2.10 N means that the magnet is capable of holding a weight many times exceeding its own mass of 0.05 g. 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 3 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 diametrically if your project requires it.

Pros and cons of Nd₂Fe₁₄B magnets.

Pros

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

They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (in laboratory conditions),
They have excellent resistance to weakening of magnetic properties due to opposing magnetic fields,
Thanks to the shimmering finish, the coating of Ni-Cu-Ni, gold, or silver gives an aesthetic appearance,
The surface of neodymium magnets generates a intense magnetic field – this is a key feature,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
Considering the possibility of accurate shaping and customization to specialized projects, NdFeB magnets can be manufactured in a wide range of shapes and sizes, which amplifies use scope,
Key role in high-tech industry – they serve a role in HDD drives, electromotive mechanisms, precision medical tools, as well as modern systems.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which enables their usage in small systems

Limitations

Cons of neodymium magnets: tips and applications.

Brittleness is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a strong case, which not only protects them against impacts but also raises their durability
When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
Limited possibility of producing nuts in the magnet and complicated shapes - preferred is cover - magnetic holder.
Potential hazard related to microscopic parts of magnets are risky, if swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, small elements of these devices can complicate diagnosis medical after entering the body.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Lifting parameters

Best holding force of the magnet in ideal parameters – what it depends on?

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

with the use of a yoke made of low-carbon steel, ensuring full magnetic saturation
possessing a thickness of min. 10 mm to ensure full flux closure
with a plane free of scratches
under conditions of ideal adhesion (surface-to-surface)
under perpendicular force direction (90-degree angle)
in stable room temperature

Practical aspects of lifting capacity – factors

Holding efficiency is influenced by specific conditions, mainly (from priority):

Gap between surfaces – even a fraction of a millimeter of distance (caused e.g. by varnish or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
Steel type – low-carbon steel gives the best results. Alloy steels reduce magnetic properties and holding force.
Surface condition – smooth surfaces guarantee perfect abutment, which increases force. Uneven metal reduce efficiency.
Thermal conditions – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).

Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate reduces the load capacity.

Safety rules for work with neodymium magnets

Health Danger

Patients with a heart stimulator should keep an absolute distance from magnets. The magnetic field can interfere with the operation of the life-saving device.

Thermal limits

Regular neodymium magnets (grade N) undergo demagnetization when the temperature surpasses 80°C. The loss of strength is permanent.

Choking Hazard

Product intended for adults. Tiny parts can be swallowed, leading to serious injuries. Keep away from children and animals.

Machining danger

Fire hazard: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this risks ignition.

Magnet fragility

Despite metallic appearance, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.

GPS Danger

A strong magnetic field disrupts the functioning of magnetometers in phones and GPS navigation. Maintain magnets near a smartphone to avoid damaging the sensors.

Cards and drives

Device Safety: Neodymium magnets can ruin payment cards and delicate electronics (pacemakers, hearing aids, timepieces).

Serious injuries

Pinching hazard: The attraction force is so great that it can cause blood blisters, crushing, and even bone fractures. Protective gloves are recommended.

Allergic reactions

It is widely known that nickel (the usual finish) is a strong allergen. If you have an allergy, prevent direct skin contact or choose coated magnets.

Conscious usage

Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.
