Grip strength weakens significantly with every subsequent millimeter of spacing. Remember that even a microscopic distance (e.g., dirt, paint, veneer) significantly diminishes the holding power. Neodymiums work strongest at the point of direct contact; air break weakens the force. Analyze how rapidly the pull force plummet, when the magnet does not touch directly to the steel surface. When planning the mounting, eliminate unnecessary gaps.

The following data presents the estimated holding capacity needed to initiate the downward movement of the magnet vertically on a vertical steel wall (considering standard friction coefficient). The holding force is a function of the distance between the magnet and the metal.

Table 3: Vertical assembly (shearing) - vertical pull

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	1.48 kg / 3.26 LBS 1479.0 g / 14.5 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.99 kg / 2.17 LBS 986.0 g / 9.7 N

When hanging a magnet on a upright plane (e.g., a fridge), it will only hold just approx. 20%-30% of its maximum pull force. Gravity as well as a weak degree of grip mean that holders move down faster than they pull off. Want to create a wall mount? Note that the shear force is significantly lower than the perpendicular breakaway force. On a slippery surface, the magnet will slide down under a noticeably lighter load. Using a rubber coating can drastically increase the grip.

A thin metal plate cannot focus the full magnetic flux, which wastes potential of the holder. Should you install a neodymium to a too thin substrate, the magnetism will pass right through and the pull force will drop sharply. To squeeze full efficiency of this neodymium's power, you require a sufficiently solid piece of steel. The saturation effect means that on thin elements (e.g., appliance housings), the holder shows lower pull force. We advise picking the steel thickness according to the table below.

Standard neodymium magnets lose parameters past the thermal threshold. Avoid high temperatures – excessive heat can irreversibly demagnetize this magnet. As the temperature rises, the neodymium's capacity momentarily lowers. Do not use this product close to heaters higher than its working range. Too high temperature will cause irreversible degradation of magnetism.

*Technical advisory: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Low-profile magnets (low Pc) may lose charge permanently under lower heat stress compared to rod magnets. Warning indicator in the table indicates permanent field degradation for this specific geometry.

Two magnets interact from a wider radius than a neodymium and metal combination. The setup of magnet-to-magnet creates a more powerful interaction and a further horizon of action. Planning to create a solid fastener? Use a pair of magnets instead of a neodymium and a steel. Exercise caution that when connecting a pair of magnets, the pinch force is massive. The repulsion force is a bit weaker than the attraction, but still large.
*Field value between like poles reaches ~0 Gs in the exact middle of the gap (due to field cancellation).
Note: Figures apply to shear force of dual same neodymium magnets (friction ~0.15 for Ni-Ni coating).

A strong magnetic field poses a serious hazard to electronic devices as well as medical implants. These neodymiums produce a flux that disrupts operation of sensitive medical devices. Notice: the invisible magnetic field passes through tissues and plastic. Increased vigilance must be exercised by people with cochlear implants and insulin pumps. The risk also applies to: automatic timepieces, remotes, speakers, and screens. Do not place the magnet near cards, hard drives, or precise measuring instruments.

NdFeB products are delicate – a violent impact against metal risks their cracking. Watch the impact speed – a magnet released freely becomes dangerous. Striking energy can trigger coating fragments or painful pinches to fingers. Always hold the magnet during bringing near metal so it doesn't slam with momentum against the steel surface. A collision at high speed means shattering of the magnet. Wear eye protection when playing with powerful specimens.

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. However, remember the water resistance when pulling the rope quickly.

1. Wall mount (shear)

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

2. Steel thickness impact

*Thin metal sheet (e.g. 0.5mm PC case) significantly reduces the holding force.

3. Thermal stability

*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) = 0.71

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 offered product is a very strong cylinder magnet, produced from modern NdFeB material, which, with dimensions of Ø12x8 mm, guarantees the highest energy density. This specific item features an accuracy of ±0.1mm and industrial build quality, making it an ideal solution for the most demanding engineers and designers. As a magnetic rod with impressive force (approx. 4.93 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring lightning-fast order fulfillment. Furthermore, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.

It successfully proves itself in DIY projects, advanced robotics, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 48.32 N with a weight of only 6.79 g, this cylindrical magnet is indispensable in electronics 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 professional component. To ensure long-term durability in automation, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.

Magnets N38 are suitable for the majority of applications in modeling and machine building, where extreme miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø12x8), 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 12 mm and height 8 mm. The key parameter here is the holding force amounting to approximately 4.93 kg (force ~48.32 N), which, with such compact dimensions, proves the high grade 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 12 mm. Such an arrangement is standard 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 diametrically if your project requires it.

Advantages as well as disadvantages of rare earth magnets.

Pros

Apart from their consistent magnetism, neodymium magnets have these key benefits:

They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (in laboratory conditions),
They feature excellent resistance to magnetic field loss as a result of external fields,
In other words, due to the metallic finish of nickel, the element becomes visually attractive,
They feature high magnetic induction at the operating surface, which improves attraction properties,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
Possibility of accurate shaping as well as optimizing to defined needs,
Significant place in modern technologies – they are commonly used in mass storage devices, electric motors, diagnostic systems, as well as other advanced devices.
Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which makes them useful in small systems

Disadvantages

Characteristics of disadvantages of neodymium magnets: weaknesses and usage proposals

To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
Due to limitations in realizing nuts and complex shapes in magnets, we propose using casing - magnetic holder.
Health risk to health – tiny shards of magnets can be dangerous, in case of ingestion, which gains importance in the context of child health protection. Furthermore, small elements of these devices can be problematic in diagnostics medical in case of swallowing.
Due to expensive raw materials, their price exceeds standard values,

Holding force characteristics

Optimal lifting capacity of a neodymium magnet – what affects it?

The force parameter is a measurement result performed under specific, ideal conditions:

using a base made of high-permeability steel, functioning as a magnetic yoke
with a thickness of at least 10 mm
characterized by lack of roughness
without the slightest air gap between the magnet and steel
during pulling in a direction vertical to the mounting surface
at ambient temperature room level

Lifting capacity in practice – influencing factors

During everyday use, the actual holding force is determined by several key aspects, listed from the most important:

Distance (between the magnet and the plate), since even a tiny distance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to paint, corrosion or debris).
Angle of force application – highest force is available only during pulling at a 90° angle. The shear force of the magnet along the plate is typically many times lower (approx. 1/5 of the lifting capacity).
Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of generating force.
Chemical composition of the base – low-carbon steel attracts best. Alloy admixtures reduce magnetic permeability and holding force.
Surface finish – full contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
Thermal conditions – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Moreover, even a small distance between the magnet’s surface and the plate lowers the holding force.

Warnings

Conscious usage

Before starting, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.

Fragile material

Despite metallic appearance, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.

Implant safety

For implant holders: Powerful magnets disrupt medical devices. Maintain minimum 30 cm distance or ask another person to work with the magnets.

Do not give to children

Product intended for adults. Tiny parts pose a choking risk, leading to severe trauma. Keep away from kids and pets.

Heat warning

Monitor thermal conditions. Exposing the magnet to high heat will destroy its properties and pulling force.

Hand protection

Risk of injury: The pulling power is so great that it can result in hematomas, pinching, and even bone fractures. Use thick gloves.

Warning for allergy sufferers

Certain individuals experience a contact allergy to nickel, which is the standard coating for neodymium magnets. Frequent touching may cause a rash. It is best to use safety gloves.

Data carriers

Very strong magnetic fields can corrupt files on payment cards, HDDs, and storage devices. Maintain a gap of at least 10 cm.

Dust explosion hazard

Powder created during cutting of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.

Phone sensors

Be aware: rare earth magnets generate a field that interferes with sensitive sensors. Keep a separation from your phone, device, and GPS.
