Pulling power decreases sharply with every subsequent millimeter of distance. Remember that even a microscopic distance (e.g., dirt, varnish, veneer) noticeably weakens the grip. Magnetic products operate strongest at the point of direct contact; air break weakens the force. Analyze how rapidly the pull force plummet, when the product does not adhere flatly to the steel surface. When calculating the arrangement, discard additional spacers.

This section calculates the estimated force necessary to cause the sliding of the magnet downwards on a vertical steel wall (assuming typical friction). This parameter is a function of the separation distance between the magnet and the metal.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.49 kg / 1.08 LBS 489.0 g / 4.8 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.33 kg / 0.72 LBS 326.0 g / 3.2 N

Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.82 kg / 1.80 LBS 815.0 g / 8.0 N

When mounting a holder on a vertical wall (e.g., a fridge), it will only hold just approx. 1/5 of its maximum pull force. Gravity as well as a weak degree of grip cause that holders slip easier than they pull off. Want to create a wall mount? Note that the shear force is much weaker than the maximum static pull force. On a smooth steel, the element will slip down under a much lighter weight. Application of an anti-slip coating can effectively increase the grip.

A thin sheet is unable to absorb the entire magnetic field, which weakens actual performance of the magnet. Should you install a neodymium to a thin surface, the flux will penetrate right through and the attraction force will be weaker. To squeeze 100% of this magnet's power, you need a suitably thick piece of steel. The saturation effect means that on sheet metal structures (e.g., thin profiles), the holder works worse. We recommend selecting the steel thickness according to the table below.

Classic neodymiums lose parameters after exceeding the maximum temperature. Watch out for overheating – heat can irreversibly demagnetize this product. With increasing heat, the neodymium's power temporarily decreases. Refrain from using this magnet near heat sources higher than its working range. Ignoring the limit will cause destruction of magnetism.

*Technical advisory: Thermal stability is determined by both grade, and the Permeance Coefficient Pc. Low-profile magnets (pancake types) are more susceptible to demagnetization sooner than long magnets. The danger warning in the table points to a risk of irreversible loss for this particular item.

Two magnetic products attract each other from a much further distance than a neodymium and metal combination. Such a system of two magnets generates a stronger field and a further horizon of action. Designing a solid fastener? Apply two magnets instead of one magnet and a steel. Be careful that when bringing together two magnets, the pinch force is huge. The repulsion force is marginally weaker than the connection force, but still impressive.
*Flux density in repulsion mode is approximately ~0 Gs in the exact middle between the magnets (caused by magnetic field nullification).
Note: Figures refer to shear force of a pair of matching magnets (friction ~0.15 for Ni-Ni plating).

Table 7: Hazards (implants) - precautionary measures
MW 20x2 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	6.5 cm
Hearing aid	10 Gs (1.0 mT)	5.0 cm
Timepiece	20 Gs (2.0 mT)	4.0 cm
Phone / Smartphone	40 Gs (4.0 mT)	3.0 cm
Remote	50 Gs (5.0 mT)	3.0 cm
Payment card	400 Gs (40.0 mT)	1.0 cm
HDD hard drive	600 Gs (60.0 mT)	1.0 cm

Extremely neodym field poses a large risk to IT equipment as well as pacemakers. These NdFeB products produce a flux that disrupts operation of digital equipment. Remember: the invisible magnetic field acts through matter and plastic. Exceptional care must be exercised by people with cochlear implants and insulin pumps. The risk also applies to: automatic timepieces, car keys, speakers, and screens. Do not place the magnet near cards, HDD media, or precise measuring instruments.

Table 8: Dynamics (cracking risk) - collision effects
MW 20x2 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	19.87 km/h (5.52 m/s)	0.07 J
30 mm	32.51 km/h (9.03 m/s)	0.19 J
50 mm	41.95 km/h (11.65 m/s)	0.32 J
100 mm	59.33 km/h (16.48 m/s)	0.64 J

NdFeB products are delicate – a violent impact against metal causes immediate chipping. Watch the impact speed – a neodymium left loose speeds with massive force. Striking energy can destroy the magnet or painful pinches to skin. Be sure to control the product during installation so it doesn't hit violently against the metal. A collision at high speed ends with a crack of the magnet. Wear safety glasses 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!

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. Wall mount (shear)

*Caution: On a vertical wall, the magnet retains just ~20% of its nominal pull.

2. Steel saturation

*Thin metal sheet (e.g. 0.5mm PC case) severely weakens 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) = 0.16

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 offered product is an incredibly powerful rod magnet, made from durable NdFeB material, which, at dimensions of Ø20x2 mm, guarantees the highest energy density. This specific item is characterized by a tolerance of ±0.1mm and industrial build quality, making it an ideal solution for the most demanding engineers and designers. As a magnetic rod with significant force (approx. 1.63 kg), this product is available off-the-shelf from our European logistics center, ensuring quick order fulfillment. Furthermore, its Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is perfect for building generators, advanced sensors, and efficient magnetic separators, where field concentration on a small surface counts. Thanks to the high power of 16.02 N with a weight of only 4.71 g, this cylindrical magnet is indispensable in electronics and wherever low weight is crucial.

Since our magnets have a tolerance of ±0.1mm, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 20.1 mm) using epoxy glues. To ensure stability in industry, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing high repeatability 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 the strongest magnets in the same volume (Ø20x2), 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 20 mm and height 2 mm. The value of 16.02 N means that the magnet is capable of holding a weight many times exceeding its own mass of 4.71 g. The product has a [NiCuNi] coating, which protects the surface against external factors, giving it an aesthetic, silvery shine.

This rod magnet is magnetized axially (along the height of 2 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 through the diameter if your project requires it.

Advantages and disadvantages of neodymium magnets.

Advantages

Besides their tremendous magnetic power, neodymium magnets offer the following advantages:

They do not lose power, even over nearly 10 years – the drop in power is only ~1% (based on measurements),
Magnets very well defend themselves against loss of magnetization caused by foreign field sources,
A magnet with a shiny silver surface has an effective appearance,
Magnetic induction on the top side of the magnet is very high,
Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for action at temperatures reaching 230°C and above...
Possibility of custom forming as well as optimizing to precise needs,
Key role in modern industrial fields – they are used in magnetic memories, electric drive systems, advanced medical instruments, as well as other advanced devices.
Thanks to their power density, small magnets offer high operating force, occupying minimum space,

Cons

Disadvantages of NdFeB magnets:

At strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
Neodymium magnets decrease their strength 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
They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
Limited possibility of creating nuts in the magnet and complex shapes - recommended is cover - magnet mounting.
Potential hazard resulting from small fragments of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child health protection. Furthermore, small components of these devices can disrupt the diagnostic process medical after entering the body.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Holding force characteristics

Highest magnetic holding force – what contributes to it?

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

with the use of a yoke made of special test steel, guaranteeing maximum field concentration
possessing a massiveness of min. 10 mm to ensure full flux closure
with a plane free of scratches
without any insulating layer between the magnet and steel
under perpendicular application of breakaway force (90-degree angle)
at conditions approx. 20°C

Practical aspects of lifting capacity – factors

Real force is affected by working environment parameters, including (from most important):

Gap between surfaces – every millimeter of distance (caused e.g. by varnish or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
Direction of force – maximum parameter is obtained only during pulling at a 90° angle. The shear force of the magnet along the surface is standardly several times smaller (approx. 1/5 of the lifting capacity).
Element thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
Material type – the best choice is pure iron steel. Hardened steels may attract less.
Plate texture – ground elements guarantee perfect abutment, which increases field saturation. Uneven metal weaken the grip.
Temperature – temperature increase causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity was assessed with the use of a polished steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, however under attempts to slide the magnet the holding force is lower. In addition, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.

Safe handling of NdFeB magnets

Powerful field

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

Sensitization to coating

Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction happens, immediately stop handling magnets and use protective gear.

Physical harm

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

Combustion hazard

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

Operating temperature

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

Medical implants

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

Precision electronics

An intense magnetic field interferes with the operation of magnetometers in phones and GPS navigation. Maintain magnets close to a device to prevent damaging the sensors.

Choking Hazard

Product intended for adults. Tiny parts pose a choking risk, causing serious injuries. Store out of reach of kids and pets.

Material brittleness

NdFeB magnets are ceramic materials, meaning they are fragile like glass. Impact of two magnets leads to them breaking into small pieces.

Protect data

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