Magnetic force drops significantly per each millimeter of spacing. Keep in mind that even a very thin break (e.g., dirt, varnish, veneer) noticeably diminishes the holding power. Magnets operate optimally at the point of direct contact; air break nullifies the power. Analyze how quickly the load capacity plummet, when the magnet does not touch directly to the steel surface. When planning the assembly, discard unnecessary gaps.

The table below shows the estimated force sufficient to initiate the sliding of the magnet down along a vertical steel plate (considering typical friction). This value varies with the separation distance between the magnet and the metal.

Table 3: Wall mounting (shearing) - behavior on slippery surfaces
MW 6x2 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.26 kg / 0.57 LBS 258.0 g / 2.5 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.17 kg / 0.38 LBS 172.0 g / 1.7 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.09 kg / 0.19 LBS 86.0 g / 0.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.43 kg / 0.95 LBS 430.0 g / 4.2 N

When placing a element on a upright surface (e.g., a board), it will only hold barely about 1/5 of nominal attraction strength. Gravity and a low friction coefficient mean that holders move down easier than they detach. Want to create a hanger? Consider that the shear force is significantly lower than the perpendicular breakaway force. On a slippery surface, the element will give way down under a much lighter cargo. Using a rubber layer can significantly raise the stability.

A too thin steel is not enough to take in the full magnetic flux, which wastes potential of the magnet. If you install a neodymium to a too thin substrate, the magnetism will penetrate right through and the attraction force will be weaker. To utilize full efficiency of this neodymium's potential, you require a sufficiently solid backing of metal. The material oversaturation causes that on delicate walls (e.g., thin profiles), the magnet holds weaker. We advise picking the steel thickness based on the following data.

Ordinary NdFeB products irreversibly lose parameters past the thermal threshold. Protect against heat – excessive heat can irreversibly destroy this product. With increasing heat, the neodymium's power temporarily lowers. Refrain from using this product close to ovens exceeding its safe range. Exceeding the critical threshold will lead to permanent loss of magnetism.

*Important note: Thermal stability depends not only on the material grade, but also on the magnet's shape. Flat magnets (low Pc) may lose charge permanently sooner than long magnets. Red status in the table indicates permanent field degradation for this particular item.

Two magnetic products interact from a much further distance than a magnet and steel setup. Such a system of two magnets creates a more powerful interaction and a larger range of operation. Want to build a solid fastener? Apply two magnets instead of one magnet and a striker plate. Exercise caution that when connecting a pair of magnets, the collision energy is extreme. The levitation is a bit weaker than the attraction, but still significant.
*Flux density between like poles is approximately ~0 Gs at the geometric center between the magnets (caused by magnetic field nullification).
Important: Estimates refer to shear force of a pair of matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

Extremely neodym field poses a large risk to IT equipment and medical implants. These neodymiums generate a flux that destroys function of digital equipment. Remember: the unseen radiation passes through tissues and housings. Increased vigilance must be exercised by people with cochlear implants and drug dispensers. The risk also applies to: mechanical watches, car keys, speakers, and displays. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Magnetic elements are prone to chipping – a collision with steel risks their cracking. Watch the impact speed – a neodymium left loose speeds with massive force. Impact energy can cause material chips or dangerous crushing to skin. Hold the magnet firmly during mounting so it doesn't hit with great force against the steel surface. A contact at a velocity of dozens of km/h almost guarantees destruction of the neodymium. Use safety goggles when playing 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!

Contrary to myths, water does not block the magnetic field. However, remember the water resistance when pulling the rope quickly.

1. Sliding resistance

*Note: On a vertical wall, the magnet retains only ~20% of its max power.

2. Efficiency vs thickness

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

3. Heat tolerance

*For N38 grade, 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) = 0.44

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 presented product is a very strong cylinder magnet, made from modern NdFeB material, which, with dimensions of Ø6x2 mm, guarantees optimal power. The MW 6x2 / N38 model is characterized by a tolerance of ±0.1mm and industrial build quality, making it an ideal solution for professional engineers and designers. As a cylindrical magnet with significant force (approx. 0.86 kg), this product is in stock from our European logistics center, ensuring lightning-fast order fulfillment. Moreover, its Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.

It finds application in modeling, advanced robotics, and broadly understood industry, serving as a positioning or actuating element. Thanks to the pull force of 8.43 N with a weight of only 0.42 g, this rod is indispensable in electronics and wherever every gram matters.

Due to the brittleness of the NdFeB material, we absolutely advise against force-fitting (so-called press-fit), as this risks chipping the coating of this professional component. To ensure long-term durability in industry, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.

Magnets NdFeB grade N38 are strong enough for the majority of applications in modeling and machine building, where excessive miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø6x2), 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 6 mm and height 2 mm. The key parameter here is the lifting capacity amounting to approximately 0.86 kg (force ~8.43 N), which, with such compact dimensions, proves the high grade of the NdFeB material. The product has a [NiCuNi] coating, which protects the surface 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 6 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 through the diameter if your project requires it.

Advantages and disadvantages of rare earth magnets.

Advantages

In addition to their magnetic capacity, neodymium magnets provide the following advantages:

Their strength is durable, and after around 10 years it decreases only by ~1% (according to research),
Neodymium magnets are highly resistant to demagnetization caused by external interference,
In other words, due to the reflective layer of gold, the element is aesthetically pleasing,
Neodymium magnets deliver maximum magnetic induction on a small area, which allows for strong attraction,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
Thanks to modularity in designing and the capacity to customize to unusual requirements,
Huge importance in advanced technology sectors – they find application in data components, brushless drives, medical equipment, and other advanced devices.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Weaknesses

What to avoid - cons of neodymium magnets and ways of using them

To avoid cracks under impact, we suggest using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
Magnets exposed to a humid environment can rust. Therefore when using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
We suggest casing - magnetic mechanism, due to difficulties in creating threads inside the magnet and complicated forms.
Possible danger resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which is particularly important in the context of child health protection. Furthermore, small components of these devices can complicate diagnosis medical after entering the body.
Due to expensive raw materials, their price is higher than average,

Lifting parameters

Maximum lifting capacity of the magnet – what it depends on?

Information about lifting capacity was defined for the most favorable conditions, including:

using a base made of mild steel, functioning as a magnetic yoke
possessing a thickness of minimum 10 mm to ensure full flux closure
with an ideally smooth touching surface
under conditions of gap-free contact (metal-to-metal)
under perpendicular force vector (90-degree angle)
at room temperature

Magnet lifting force in use – key factors

It is worth knowing that the magnet holding will differ depending on elements below, in order of importance:

Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by veneer or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
Chemical composition of the base – low-carbon steel attracts best. Higher carbon content decrease magnetic properties and lifting capacity.
Plate texture – ground elements guarantee perfect abutment, which increases force. Rough surfaces weaken the grip.
Heat – NdFeB sinters have a negative temperature coefficient. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).

Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under perpendicular forces, however under attempts to slide the magnet the load capacity is reduced by as much as 5 times. In addition, even a small distance between the magnet and the plate decreases the holding force.

Safety rules for work with neodymium magnets

Pacemakers

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

Respect the power

Exercise caution. Rare earth magnets attract from a distance and connect with huge force, often faster than you can move away.

No play value

NdFeB magnets are not toys. Swallowing several magnets can lead to them pinching intestinal walls, which constitutes a direct threat to life and requires immediate surgery.

Flammability

Drilling and cutting of neodymium magnets carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.

Heat warning

Do not overheat. Neodymium magnets are sensitive to temperature. If you need resistance above 80°C, look for HT versions (H, SH, UH).

Fragile material

NdFeB magnets are sintered ceramics, meaning they are prone to chipping. Collision of two magnets will cause them cracking into shards.

Phone sensors

A strong magnetic field negatively affects the functioning of magnetometers in phones and GPS navigation. Keep magnets near a smartphone to prevent breaking the sensors.

Cards and drives

Intense magnetic fields can erase data on credit cards, hard drives, and storage devices. Maintain a gap of min. 10 cm.

Hand protection

Mind your fingers. Two large magnets will snap together instantly with a force of massive weight, destroying everything in their path. Be careful!

Sensitization to coating

Some people have a hypersensitivity to nickel, which is the common plating for neodymium magnets. Extended handling may cause a rash. We suggest use protective gloves.

Attention! Details about hazards in the article: Safety of working with magnets.
