Magnetic force drops sharply with every subsequent millimeter of gap. Note that every additional insulation layer (e.g., contamination, varnish, rust) strongly weakens the grip. Magnets hold most effectively at the point of direct contact; distance kills the power. Observe how flashily the load capacity fall, when the magnet does not touch tightly to the steel surface. When calculating the assembly, discard redundant distances.

The following data presents the estimated force needed to initiate the slippage of the magnet downwards against a vertical steel wall (considering typical friction). This value depends on the distance between the magnet and the metal.

Table 3: Wall mounting (shearing) - vertical pull
MW 10x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.64 kg / 1.42 pounds 645.0 g / 6.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.43 kg / 0.95 pounds 430.0 g / 4.2 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.22 kg / 0.47 pounds 215.0 g / 2.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.08 kg / 2.37 pounds 1075.0 g / 10.5 N

When placing a magnet on a upright plane (e.g., a car body), it will only hold barely about 1/5 of its maximum pull force. Gravitational force as well as a weak degree of grip influence the fact that magnets slip faster than they pull off. Planning a wall mount? Consider that the shear force is noticeably lower than the perpendicular breakaway force. On a slippery surface, the magnet will slip down under a much lighter cargo. Application of an anti-slip pad can effectively increase the grip.

A thin sheet is not enough to absorb the full magnetic flux, which wastes potential of the holder. Should you mount a strong magnet to a weak sheet, the flux will pass right through and the attraction force will be weaker. To utilize the maximum of this magnet's potential, you require a sufficiently solid element of metal. The saturation effect means that on thin elements (e.g., appliance housings), the magnet holds weaker. We recommend selecting the steel thickness from these parameters.

Ordinary NdFeB products lose parameters after exceeding the maximum temperature. Avoid high temperatures – excessive heat can permanently destroy this magnet. As the temperature rises, the magnet's force momentarily lowers. Refrain from using this magnet close to ovens exceeding its safe range. Exceeding the critical threshold will cause destruction of magnetic properties.

*Engineering note: Thermal stability is determined by both grade, but also on the magnet's shape. Low-profile magnets (pancake types) are more susceptible to demagnetization at lower temperatures than taller cylinders. Red status in the table signals permanent field degradation for this particular item.

Two magnetic products interact from a wider radius than a neodymium and metal setup. Such a system of magnet-to-magnet creates a more powerful interaction and a further horizon of action. Planning to create a solid fastener? Utilize two neodymiums instead of a neodymium and a striker plate. Exercise caution that when attracting two neodymiums, the collision energy is massive. The repulsion force is a bit weaker than the attraction, but still large.
*The magnetic induction in repulsion mode reaches ~0 Gs in the exact middle between the magnets (resulting from vector opposition).
Note: Figures show shear force of dual identical magnets (friction coefficient ~0.15 for Ni-Ni layer).

Extremely neodym field poses a serious hazard to electronic devices and medical implants. These magnets generate a field that prevents correct functioning of sensitive medical devices. Notice: the invisible magnetic field penetrates the body and housings. Exceptional care must be exercised by people with cochlear implants and drug dispensers. Also at risk are: automatic timepieces, car keys, membranes, and displays. Avoid contact with magnetic cards, HDD media, or sensitive navigation tools.

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 cause material chips or injury to fingers. Always hold the magnet during installation so it doesn't slam with momentum against the metal. A collision at high speed ends with a crack of the magnet. Use safety goggles when handling with large magnets.

Rust risk: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

The magnetic field penetrates through water without any losses. Buoyancy helps in lifting finds.

1. Vertical hold

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

2. Steel thickness impact

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

3. Thermal stability

*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

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 offered product is an extremely powerful cylinder magnet, composed of modern NdFeB material, which, at dimensions of Ø10x3 mm, guarantees optimal power. The MW 10x3 / N38 component is characterized by an accuracy of ±0.1mm and industrial build quality, making it a perfect solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 2.15 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring lightning-fast order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

This model is ideal for building electric motors, advanced Hall effect sensors, and efficient magnetic separators, where maximum induction on a small surface counts. Thanks to the high power of 21.04 N with a weight of only 1.77 g, this rod is indispensable in miniature devices and wherever every gram matters.

Due to the delicate structure of the ceramic sinter, you must not use force-fitting (so-called press-fit), as this risks immediate cracking of this precision component. To ensure stability in automation, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.

Grade N38 is the most popular standard for professional neodymium magnets, offering a great economic balance and operational stability. If you need even stronger magnets in the same volume (Ø10x3), 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 10 mm and height 3 mm. The value of 21.04 N means that the magnet is capable of holding a weight many times exceeding its own mass of 1.77 g. 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 10 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.

Advantages and disadvantages of Nd₂Fe₁₄B magnets.

Benefits

Apart from their superior magnetic energy, neodymium magnets have these key benefits:

They have stable power, and over nearly ten years their attraction force decreases symbolically – ~1% (according to theory),
They have excellent resistance to magnetic field loss as a result of opposing magnetic fields,
A magnet with a shiny gold surface is more attractive,
Magnets possess very high magnetic induction on the outer layer,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
Thanks to flexibility in shaping and the capacity to adapt to individual projects,
Universal use in advanced technology sectors – they find application in hard drives, brushless drives, medical equipment, as well as industrial machines.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Weaknesses

Disadvantages of neodymium magnets:

Brittleness is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a special holder, which not only protects them against impacts but also increases their durability
We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture
Due to limitations in creating nuts and complex forms in magnets, we propose using cover - magnetic mechanism.
Health risk resulting from small fragments of magnets pose a threat, in case of ingestion, which is particularly important in the context of child health protection. Additionally, small components of these magnets can disrupt the diagnostic process medical when they are in the body.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities

Pull force analysis

Detachment force of the magnet in optimal conditions – what it depends on?

The load parameter shown concerns the peak performance, obtained under ideal test conditions, namely:

with the use of a sheet made of low-carbon steel, ensuring full magnetic saturation
possessing a thickness of at least 10 mm to avoid saturation
characterized by even structure
under conditions of no distance (surface-to-surface)
during detachment in a direction vertical to the mounting surface
at standard ambient temperature

Key elements affecting lifting force

Please note that the magnet holding will differ influenced by elements below, starting with the most relevant:

Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
Loading method – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
Plate material – mild steel attracts best. Higher carbon content lower magnetic properties and holding force.
Surface quality – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
Thermal factor – high temperature weakens pulling force. Too high temperature can permanently demagnetize the magnet.

Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, whereas under shearing force the holding force is lower. Moreover, even a small distance between the magnet and the plate reduces the holding force.

Safe handling of neodymium magnets

Avoid contact if allergic

Medical facts indicate that nickel (standard magnet coating) is a strong allergen. If your skin reacts to metals, refrain from touching magnets with bare hands or choose encased magnets.

Flammability

Mechanical processing of NdFeB material poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.

Medical interference

Life threat: Strong magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.

Do not give to children

Only for adults. Small elements can be swallowed, leading to severe trauma. Keep out of reach of children and animals.

Caution required

Handle with care. Neodymium magnets act from a long distance and connect with huge force, often faster than you can move away.

Magnetic interference

Be aware: neodymium magnets produce a field that interferes with sensitive sensors. Keep a separation from your phone, device, and navigation systems.

Serious injuries

Protect your hands. Two powerful magnets will snap together immediately with a force of several hundred kilograms, destroying anything in their path. Exercise extreme caution!

Eye protection

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

Safe distance

Device Safety: Strong magnets can damage payment cards and delicate electronics (pacemakers, hearing aids, mechanical watches).

Power loss in heat

Standard neodymium magnets (N-type) lose magnetization when the temperature goes above 80°C. This process is irreversible.
