Pulling power weakens significantly with every subsequent millimeter of distance. Note that even the smallest gap (e.g., dirt, paint, veneer) significantly weakens the grip. Magnetic products work optimally during direct contact; air break kills the force. Notice how rapidly the pull force drop, when the magnet does not touch directly to the steel surface. When calculating the arrangement, discard redundant distances.

The following data presents the theoretical force required to cause the slippage of the magnet down along a vertical metal surface (considering standard friction coefficient). The holding force varies with the distance between the magnet and the surface.

Table 3: Vertical assembly (sliding) - vertical pull
MW 10x20 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.67 kg / 1.47 LBS 669.0 g / 6.6 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.45 kg / 0.98 LBS 446.0 g / 4.4 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.22 kg / 0.49 LBS 223.0 g / 2.2 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.12 kg / 2.46 LBS 1115.0 g / 10.9 N

When placing a holder on a upright surface (e.g., a board), it you can count on just about 20%-30% of its maximum pull force. Gravity as well as a weak degree of grip cause that products slide down easier than they pull off. Want to create a vertical fastening? Remember that the sliding force is noticeably lower than the perpendicular breakaway force. On a painted metal, the element will give way down under a noticeably lighter weight. Application of an anti-slip pad can effectively raise the stability.

A thin sheet is not enough to focus the full magnetic flux, which weakens actual performance of the magnet. Should you install a neodymium to a thin surface, the field will pass right through and the attraction force will be weaker. To utilize full efficiency of this magnet's power, you require a sufficiently solid backing of steel. The material oversaturation causes that on delicate walls (e.g., appliance housings), the product shows lower pull force. We advise picking the steel thickness according to the table below.

Classic neodymiums irreversibly lose power after exceeding the maximum temperature. Watch out for overheating – high temperature can permanently destroy this magnet. With every degree above norm, the magnet's capacity temporarily decreases. Avoid using this product in hot environments exceeding its operating temperature limit. Exceeding the critical threshold will cause irreversible degradation of magnetic properties.

*Engineering note: Thermal stability is determined by both grade, as well as the dimension ratios. Thin magnets (low Pc) are more susceptible to demagnetization sooner than taller cylinders. Warning indicator in the table points to a risk of irreversible loss for this particular item.

Two magnets interact from a much further distance than a magnet and steel combination. Such a system of magnet-to-magnet generates a stronger field and a larger range of action. Planning to create a solid fastener? Apply two magnets instead of a neodymium and a steel. Remember that when attracting two neodymiums, the collision energy is massive. The levitation is slightly lower than the connection force, but still impressive.
*Field value between like poles reaches ~0 Gs at the midpoint of the gap (caused by magnetic field nullification).
Attention: Calculations apply to friction force of two matching neodymium magnets (friction ~0.15 for Ni-Ni plating).

A strong magnetic field is a real danger to IT equipment and pacemakers. These NdFeB products produce a field that prevents correct functioning of sensitive medical devices. Be aware: the invisible magnetic field acts through matter and glass. Increased vigilance must be exercised by people with cochlear implants and insulin pumps. Influence will be felt by: mechanical watches, remotes, membranes, and screens. Do not bring the product near payment cards, hard drives, or sensitive navigation tools.

Magnetic elements are prone to chipping – a violent impact against metal can result in shattering. Watch the impact speed – a neodymium left loose turns into a projectile. Kinetic force can cause material chips or painful pinches to skin. Always hold the magnet during bringing near metal so it doesn't slam with momentum against the metal. A contact at a velocity of dozens of km/h means shattering of the neodymium. Wear eye protection when working 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. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Wall mount (shear)

*Note: On a vertical surface, the magnet retains only approx. 20-30% of its nominal pull.

2. Steel thickness impact

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

3. Heat tolerance

*For N38 material, the critical limit is 80°C.

4. Demagnetization curve and operating point (B-H)

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 1.21

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.

This product is an incredibly powerful rod magnet, made from modern NdFeB material, which, at dimensions of Ø10x20 mm, guarantees the highest energy density. The MW 10x20 / N38 component is characterized by a tolerance of ±0.1mm and industrial build quality, making it an ideal solution for professional engineers and designers. As a magnetic rod with significant force (approx. 2.23 kg), this product is available off-the-shelf from our European logistics center, ensuring quick order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

It finds application in modeling, advanced automation, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 21.88 N with a weight of only 11.78 g, this cylindrical magnet is indispensable in miniature devices and wherever every gram matters.

Since our magnets have a very precise dimensions, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 10.1 mm) using two-component epoxy glues. 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.

Grade N38 is the most frequently chosen standard for industrial neodymium magnets, offering an optimal price-to-power ratio and operational stability. If you need the strongest magnets in the same volume (Ø10x20), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.

The presented product is a neodymium magnet with precisely defined parameters: diameter 10 mm and height 20 mm. The value of 21.88 N means that the magnet is capable of holding a weight many times exceeding its own mass of 11.78 g. The product has a [NiCuNi] coating, which secures it against external factors, giving it an aesthetic, silvery shine.

This rod magnet is magnetized axially (along the height of 20 mm), which means that the N and S poles are located on the flat, circular surfaces. 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 as well as disadvantages of neodymium magnets.

Advantages

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

They retain attractive force for around ten years – the loss is just ~1% (in theory),
They are resistant to demagnetization induced by external magnetic fields,
By covering with a shiny layer of nickel, the element acquires an modern look,
Magnets possess exceptionally strong magnetic induction on the working surface,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
Thanks to modularity in constructing and the ability to adapt to specific needs,
Huge importance in electronics industry – they find application in mass storage devices, brushless drives, medical devices, and modern systems.
Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which allows their use in miniature devices

Cons

What to avoid - cons of neodymium magnets and proposals for their use:

They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
Limited possibility of making nuts in the magnet and complex forms - preferred is casing - mounting mechanism.
Health risk to health – tiny shards of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, tiny parts of these magnets are able to complicate diagnosis medical in case of swallowing.
With mass production the cost of neodymium magnets is economically unviable,

Lifting parameters

Maximum lifting force for a neodymium magnet – what it depends on?

The force parameter is a result of laboratory testing performed under standard conditions:

with the use of a sheet made of special test steel, guaranteeing full magnetic saturation
possessing a thickness of at least 10 mm to avoid saturation
with an polished touching surface
under conditions of ideal adhesion (surface-to-surface)
during pulling in a direction perpendicular to the mounting surface
at ambient temperature room level

Practical aspects of lifting capacity – factors

Please note that the application force may be lower subject to elements below, starting with the most relevant:

Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
Angle of force application – maximum parameter is obtained only during perpendicular pulling. The shear force of the magnet along the plate is standardly many times lower (approx. 1/5 of the lifting capacity).
Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
Material type – ideal substrate is high-permeability steel. Hardened steels may generate lower lifting capacity.
Surface structure – the more even the surface, the better the adhesion and stronger the hold. Roughness creates an air distance.
Thermal factor – high temperature reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, in contrast under parallel forces the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate decreases the load capacity.

Safety rules for work with NdFeB magnets

Crushing force

Protect your hands. Two large magnets will snap together immediately with a force of several hundred kilograms, crushing everything in their path. Be careful!

Beware of splinters

Despite metallic appearance, the material is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.

Demagnetization risk

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

Electronic hazard

Powerful magnetic fields can erase data on payment cards, HDDs, and storage devices. Keep a distance of min. 10 cm.

Medical interference

People with a pacemaker have to keep an absolute distance from magnets. The magnetism can disrupt the operation of the life-saving device.

Allergy Warning

Medical facts indicate that nickel (the usual finish) is a strong allergen. If your skin reacts to metals, avoid direct skin contact or select encased magnets.

Respect the power

Use magnets with awareness. Their huge power can surprise even experienced users. Plan your moves and respect their power.

Choking Hazard

Adult use only. Tiny parts pose a choking risk, causing serious injuries. Store out of reach of children and animals.

Impact on smartphones

Note: rare earth magnets produce a field that confuses precision electronics. Keep a safe distance from your phone, device, and navigation systems.

Flammability

Fire warning: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this risks ignition.

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