Pulling power drops significantly with every mm of distance. Remember that even the smallest gap (e.g., dirt, varnish, veneer) noticeably weakens the grip. Neodymiums work optimally in perfect adhesion; distance kills the force. Observe how quickly the parameters drop, when the magnet does not adhere flatly to the steel surface. When calculating the mounting, discard additional spacers.

This section indicates the theoretical holding capacity required to initiate the shifting of the magnet down against a upright metal surface (considering typical friction coefficient). The holding force varies with the gap size between the magnet and the metal.

Table 3: Vertical assembly (sliding) - vertical pull
MW 22x10 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	4.43 kg / 9.76 pounds 4425.0 g / 43.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	2.95 kg / 6.50 pounds 2950.0 g / 28.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	1.48 kg / 3.25 pounds 1475.0 g / 14.5 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	7.38 kg / 16.26 pounds 7375.0 g / 72.3 N

When mounting a holder on a upright wall (e.g., a board), it you can count on only about 20%-30% of nominal attraction strength. Gravity and a weak degree of grip cause that holders move down easier than they pull off. Designing a hanger? Note that the sliding force is much weaker than the perpendicular breakaway force. On a painted metal, the element will slip down under a much lighter load. Application of an anti-slip coating can significantly increase the grip.

A thin metal plate is not enough to take in the full magnetic flux, which wastes potential of the magnet. Should you install a neodymium to a thin surface, the magnetism will penetrate right through and the pull force will drop sharply. To achieve 100% of this magnet's power, you require a sufficiently solid piece of steel. The saturation effect means that on sheet metal structures (e.g., appliance housings), the magnet holds weaker. We recommend selecting the steel cross-section based on the following data.

Classic neodymiums irreversibly lose power after exceeding the maximum temperature. Watch out for overheating – excessive heat can permanently demagnetize this magnet. With increasing heat, the magnet's capacity momentarily decreases. Avoid using this magnet near heat sources exceeding its working range. Exceeding the critical threshold will result in permanent loss of magnetism.

*Technical advisory: Temperature resistance is determined by both grade, and the Permeance Coefficient Pc. Flat magnets (low permeance coefficient) risk losing magnetic properties at lower temperatures than long magnets. Red status in the table signals a risk of irreversible loss for this specific geometry.

Two magnets interact from a significantly greater distance than a neodymium and metal combination. Such a system of two magnets generates a stronger field and a further horizon of performance. Planning to create a solid fastener? Apply two magnets instead of one magnet and a striker plate. Remember that when attracting two neodymiums, the impact force is massive. The levitation is a bit weaker than the connection force, but still impressive.
*The magnetic induction in repulsion mode reaches ~0 Gs in the exact middle of the gap (caused by magnetic field nullification).
Attention: Calculations show friction force of a pair of matching magnets (friction ~0.15 for Ni-Ni plating).

Extremely neodym field is a serious hazard to electronics and medical implants. These NdFeB products generate a field that disrupts operation of digital equipment. Remember: the unseen radiation penetrates the body and plastic. Special caution must be taken by people with cochlear implants and drug dispensers. Also at risk are: automatic timepieces, remotes, membranes, and screens. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Table 8: Impact energy (cracking risk) - collision effects
MW 22x10 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	24.22 km/h (6.73 m/s)	0.65 J
30 mm	39.77 km/h (11.05 m/s)	1.74 J
50 mm	51.30 km/h (14.25 m/s)	2.89 J
100 mm	72.54 km/h (20.15 m/s)	5.79 J

NdFeB products are delicate – a violent impact against metal can result in shattering. Control the attraction moment – a neodymium left loose becomes dangerous. Impact energy can destroy the magnet or injury to fingers. Always hold the magnet during installation so it doesn't hit violently against the metal. A collision at high speed almost guarantees destruction of the magnet. Use safety goggles when handling with powerful specimens.

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. Wall mount (shear)

*Caution: On a vertical surface, the magnet holds only ~20% of its perpendicular strength.

2. Steel thickness impact

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

3. Heat tolerance

*For N38 material, 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) = 0.55

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 rod magnet, manufactured from durable NdFeB material, which, with dimensions of Ø22x10 mm, guarantees maximum efficiency. This specific item features an accuracy of ±0.1mm and professional build quality, making it a perfect solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 14.75 kg), this product is available off-the-shelf from our European logistics center, ensuring rapid order fulfillment. Furthermore, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is ideal for building electric motors, advanced sensors, and efficient magnetic separators, where maximum induction on a small surface counts. Thanks to the pull force of 144.65 N with a weight of only 28.51 g, this rod is indispensable in electronics and wherever every gram matters.

Since our magnets have a tolerance of ±0.1mm, the best method is to glue them into holes with a slightly larger diameter (e.g., 22.1 mm) using two-component epoxy glues. To ensure stability in automation, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.

Magnets NdFeB grade N38 are strong enough for 90% 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 (Ø22x10), 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 22 mm and height 10 mm. The key parameter here is the holding force amounting to approximately 14.75 kg (force ~144.65 N), which, with such defined dimensions, proves the high power 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 22 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 Nd₂Fe₁₄B magnets.

Pros

Apart from their notable power, neodymium magnets have these key benefits:

They do not lose strength, even over around ten years – the decrease in strength is only ~1% (according to tests),
They are extremely resistant to demagnetization induced by external disturbances,
The use of an shiny coating of noble metals (nickel, gold, silver) causes the element to have aesthetics,
Magnets have huge magnetic induction on the outer side,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
Possibility of accurate creating as well as adjusting to concrete conditions,
Huge importance in electronics industry – they find application in magnetic memories, electromotive mechanisms, precision medical tools, also complex engineering applications.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Limitations

Characteristics of disadvantages of neodymium magnets and ways of using them

They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also increases its resistance to damage
NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape and 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
Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
Due to limitations in realizing nuts and complicated forms in magnets, we propose using casing - magnetic mechanism.
Possible danger to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that tiny parts of these devices are able to be problematic in diagnostics medical when they are in the body.
Due to neodymium price, their price exceeds standard values,

Lifting parameters

Highest magnetic holding force – what it depends on?

The declared magnet strength represents the peak performance, obtained under ideal test conditions, meaning:

using a base made of high-permeability steel, acting as a circuit closing element
with a thickness minimum 10 mm
with a surface free of scratches
under conditions of ideal adhesion (surface-to-surface)
for force acting at a right angle (pull-off, not shear)
at temperature room level

Key elements affecting lifting force

Holding efficiency is affected by working environment parameters, mainly (from most important):

Distance – the presence of any layer (paint, dirt, gap) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
Plate material – mild steel attracts best. Alloy admixtures lower magnetic permeability and lifting capacity.
Base smoothness – the more even the plate, the larger the contact zone and higher the lifting capacity. Roughness creates an air distance.
Thermal conditions – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and at low temperatures gain strength (up to a certain limit).

Lifting capacity testing was conducted on a smooth plate of suitable thickness, under a perpendicular pulling force, in contrast under shearing force the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate reduces the holding force.

Warnings

Nickel allergy

Some people have a contact allergy to Ni, which is the standard coating for NdFeB magnets. Frequent touching can result in dermatitis. We suggest use safety gloves.

Magnetic interference

A powerful magnetic field disrupts the functioning of magnetometers in smartphones and GPS navigation. Keep magnets close to a smartphone to avoid damaging the sensors.

Mechanical processing

Fire warning: Neodymium dust is highly flammable. Do not process magnets without safety gear as this risks ignition.

Implant safety

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

Fragile material

Neodymium magnets are sintered ceramics, which means they are fragile like glass. Impact of two magnets will cause them shattering into small pieces.

Keep away from computers

Intense magnetic fields can corrupt files on credit cards, HDDs, and storage devices. Maintain a gap of min. 10 cm.

Hand protection

Big blocks can smash fingers instantly. Under no circumstances put your hand betwixt two strong magnets.

Do not give to children

Adult use only. Small elements can be swallowed, causing intestinal necrosis. Keep out of reach of kids and pets.

Safe operation

Handle magnets consciously. Their powerful strength can shock even professionals. Stay alert and respect their force.

Heat sensitivity

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

Caution! Learn more about hazards in the article: Magnet Safety Guide.
