Grip strength weakens drastically with every subsequent millimeter of gap. Remember that even a microscopic distance (e.g., contamination, varnish, rust) noticeably diminishes the holding power. Magnets work most effectively during direct contact; distance weakens the power. Observe how rapidly the parameters fall, when the product does not adhere flatly to the steel surface. When calculating the mounting, eliminate redundant distances.

The table below indicates the estimated weight limit needed to cause the downward movement of the magnet down against a vertical steel wall (assuming typical friction coefficient). This parameter is relative to the gap size between the magnet and the metal.

Table 3: Vertical assembly (shearing) - vertical pull
MW 20x35 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	2.87 kg / 6.34 LBS 2874.0 g / 28.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.92 kg / 4.22 LBS 1916.0 g / 18.8 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.96 kg / 2.11 LBS 958.0 g / 9.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	4.79 kg / 10.56 LBS 4790.0 g / 47.0 N

When placing a element on a upright plane (e.g., a board), it will only hold just about 20%-30% of its maximum pull force. Gravity and a low friction coefficient cause that holders slide down faster than they pull off. Planning a wall mount? Consider that the shear force is much weaker than the maximum static pull force. On a smooth steel, the magnet will slide down under a much lighter cargo. Application of an anti-slip pad can effectively increase the grip.

12 mm	100%	9.58 kg / 21.12 LBS 9580.0 g / 94.0 N

A thin metal plate is unable to conduct the entire magnetic field, which wastes potential of the holder. If you mount a strong magnet to a weak sheet, the flux will penetrate right through and the holding will be smaller. To squeeze the maximum of this magnet's power, you require a sufficiently solid piece of steel. The saturation effect causes that on delicate walls (e.g., thin profiles), the holder works worse. We advise picking the steel thickness according to the table below.

Ordinary NdFeB products lose strength above the temperature limit. Watch out for overheating – high temperature can irreversibly destroy this product. With increasing heat, the magnet's force temporarily drops. Refrain from using this product close to ovens higher than its working range. Exceeding the critical threshold will result in irreversible degradation of magnetism.

*Technical advisory: Thermal stability depends not only on the material grade, as well as the dimension ratios. Flat magnets (pancake types) risk losing magnetic properties sooner than long magnets. Warning indicator in the table indicates a risk of irreversible loss for this specific geometry.

Two magnetic products attract each other from a significantly greater distance than a neodymium and metal combination. The setup of magnet-to-magnet produces a massive flux and a wider radius of action. Designing a strong closure? Apply two magnets instead of one magnet and a striker plate. Exercise caution that when bringing together two magnets, the impact force is extreme. The repulsion force is a bit weaker than the attraction, but still significant.
*Flux density in repulsion mode reaches ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
* Estimates show friction force of dual identical magnets (friction ~0.15 for Ni-Ni layer).

A strong magnetic field poses a serious hazard to IT equipment and medical implants. These magnets produce a flux that prevents correct functioning of digital equipment. Notice: the invisible magnetic field passes through tissues and housings. Exceptional care must be exercised by people with cochlear implants and drug dispensers. The risk also applies to: mechanical watches, remotes, speakers, and screens. Do not place the magnet near cards, hard drives, or precise measuring instruments.

NdFeB products are very brittle – a collision with steel causes immediate chipping. Control the attraction moment – a neodymium left loose speeds with massive force. Impact energy can destroy the magnet or painful pinches to fingers. Always hold the magnet during mounting so it doesn't hit violently against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Wear safety glasses when playing 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.

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. Vertical hold

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

2. Plate thickness effect

*Thin steel (e.g. computer case) drastically limits the holding force.

3. Temperature resistance

*For standard magnets, 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) = 1.16

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 a very strong cylinder magnet, composed of modern NdFeB material, which, at dimensions of Ø20x35 mm, guarantees the highest energy density. The MW 20x35 / N38 model features high dimensional repeatability and industrial build quality, making it a perfect solution for professional engineers and designers. As a cylindrical magnet with significant force (approx. 9.58 kg), this product is in stock from our European logistics center, ensuring lightning-fast order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, guaranteeing 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 pull force of 93.97 N with a weight of only 82.47 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 chipping the coating of this professional component. To ensure stability in industry, 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 frequently chosen standard for professional neodymium magnets, offering a great economic balance and operational stability. If you need the strongest magnets in the same volume (Ø20x35), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

The presented product is a neodymium magnet with precisely defined parameters: diameter 20 mm and height 35 mm. The key parameter here is the lifting capacity amounting to approximately 9.58 kg (force ~93.97 N), which, with such compact dimensions, proves the high grade of the NdFeB material. 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 20 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.

Advantages and disadvantages of neodymium magnets.

Benefits

Besides their durability, neodymium magnets are valued for these benefits:

They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (according to literature),
They have excellent resistance to magnetic field loss due to opposing magnetic fields,
A magnet with a metallic gold surface has better aesthetics,
The surface of neodymium magnets generates a unique magnetic field – this is one of their assets,
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...
Thanks to modularity in designing and the ability to customize to complex applications,
Universal use in innovative solutions – they serve a role in computer drives, drive modules, medical equipment, also other advanced devices.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Disadvantages

Drawbacks and weaknesses of neodymium magnets: application proposals

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 shields the magnet but also improves its resistance to damage
We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
They rust in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
Limited ability of producing threads in the magnet and complicated shapes - preferred is a housing - magnet mounting.
Health risk related to microscopic parts of magnets can be dangerous, in case of ingestion, which becomes key in the aspect of protecting the youngest. It is also worth noting that small components of these devices can disrupt the diagnostic process medical when they are in the body.
With large orders the cost of neodymium magnets can be a barrier,

Lifting parameters

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

Information about lifting capacity was determined for optimal configuration, taking into account:

using a sheet made of mild steel, functioning as a magnetic yoke
whose thickness equals approx. 10 mm
characterized by smoothness
under conditions of ideal adhesion (metal-to-metal)
during pulling in a direction vertical to the mounting surface
in neutral thermal conditions

Lifting capacity in real conditions – factors

Holding efficiency impacted by working environment parameters, including (from most important):

Space between surfaces – every millimeter of distance (caused e.g. by varnish or dirt) diminishes the pulling force, often by half at just 0.5 mm.
Force direction – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet exhibits much less (typically approx. 20-30% of nominal force).
Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of generating force.
Material composition – different alloys attracts identically. High carbon content worsen the attraction effect.
Surface structure – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
Thermal environment – temperature increase causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, however under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.

Safety rules for work with neodymium magnets

Metal Allergy

Medical facts indicate that the nickel plating (standard magnet coating) is a strong allergen. For allergy sufferers, refrain from direct skin contact and choose encased magnets.

Fragile material

Neodymium magnets are ceramic materials, meaning they are fragile like glass. Impact of two magnets leads to them breaking into shards.

Phone sensors

GPS units and smartphones are extremely susceptible to magnetic fields. Direct contact with a strong magnet can decalibrate the sensors in your phone.

Dust explosion hazard

Fire hazard: Rare earth powder is explosive. Avoid machining magnets without safety gear as this risks ignition.

Warning for heart patients

Life threat: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.

Danger to the youngest

Always store magnets away from children. Choking hazard is significant, and the consequences of magnets clamping inside the body are life-threatening.

Operating temperature

Do not overheat. Neodymium magnets are sensitive to temperature. If you need operation above 80°C, look for special high-temperature series (H, SH, UH).

Hand protection

Mind your fingers. Two powerful magnets will join instantly with a force of massive weight, destroying everything in their path. Exercise extreme caution!

Protect data

Very strong magnetic fields can destroy records on credit cards, HDDs, and other magnetic media. Stay away of at least 10 cm.

Handling rules

Use magnets consciously. Their powerful strength can shock even professionals. Be vigilant and respect their power.
