Magnetic force weakens sharply with every subsequent millimeter of distance. Note that even a very thin break (e.g., dirt, varnish, dust) significantly diminishes the holding power. Magnetic products operate optimally at the point of direct contact; air break nullifies the force. See how rapidly the parameters fall, when the product does not touch tightly to the metal substrate. When designing the arrangement, discard additional spacers.

The following data indicates the estimated force needed to initiate the shifting of the magnet vertically along a upright metal surface (considering standard friction). The holding force is a function of the distance between the magnet and the metal.

Table 3: Wall mounting (sliding) - vertical pull
MW 35x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	2.78 kg / 6.12 LBS 2775.0 g / 27.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.85 kg / 4.08 LBS 1850.0 g / 18.1 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.93 kg / 2.04 LBS 925.0 g / 9.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	4.63 kg / 10.20 LBS 4625.0 g / 45.4 N

When hanging a holder on a vertical surface (e.g., a board), it will maintain only about 1/5 of its maximum pull force. Gravitational force and a low friction coefficient mean that magnets slip faster than they detach. Want to create a hanger? Remember that the sliding force is significantly lower than the maximum static pull force. On a slippery surface, the element will slide down under a significantly smaller weight. Using a rubber coating can effectively raise the stability.

A thin sheet is not enough to focus the full magnetic flux, which squanders power of the magnet. If you attach a powerful product to a too thin substrate, the flux will penetrate right through and the attraction force will be weaker. To squeeze full efficiency of this magnet's potential, you require a sufficiently solid backing of steel. The saturation effect causes that on delicate walls (e.g., appliance housings), the product shows lower pull force. We recommend selecting the steel dimension according to the table below.

Classic neodymiums irreversibly lose strength after exceeding the maximum temperature. Protect against heat – high temperature can irreversibly damage this magnet. With every degree above norm, the magnet's power briefly decreases. Refrain from using this magnet in hot environments exceeding its safe range. Ignoring the limit will lead to irreversible degradation of magnetic properties.

*Engineering note: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Low-profile magnets (pancake types) may lose charge permanently sooner than long magnets. The danger warning in the table signals permanent field degradation for this specific geometry.

Two magnetic products interact from a much further distance than a magnet and steel combination. Such a system of magnet-to-magnet creates a more powerful interaction and a larger range of operation. Designing a powerful holder? Apply two magnets instead of a neodymium and a steel. Exercise caution that when connecting a pair of magnets, the impact force is huge. The levitation is a bit weaker than the connection force, but still significant.
*The magnetic induction between like poles drops to ~0 Gs at the midpoint of the gap (due to field cancellation).
Important: Estimates show friction force of a pair of matching magnets (friction ~0.15 for Ni-Ni plating).

Table 7: Safety (HSE) (electronics) - precautionary measures
MW 35x5 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	12.5 cm
Hearing aid	10 Gs (1.0 mT)	9.5 cm
Mechanical watch	20 Gs (2.0 mT)	7.5 cm
Mobile device	40 Gs (4.0 mT)	6.0 cm
Car key	50 Gs (5.0 mT)	5.5 cm
Payment card	400 Gs (40.0 mT)	2.5 cm
HDD hard drive	600 Gs (60.0 mT)	2.0 cm

Extremely neodym field poses a real danger to electronics and pacemakers. These neodymiums produce a flux that prevents correct functioning of digital equipment. Remember: the unseen radiation penetrates the body and glass. Special caution must be exercised by people with cochlear implants and insulin pumps. The risk also applies to: automatic timepieces, remotes, membranes, and displays. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Table 8: Collisions (kinetic energy) - collision effects
MW 35x5 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	19.08 km/h (5.30 m/s)	0.51 J
30 mm	28.19 km/h (7.83 m/s)	1.11 J
50 mm	36.13 km/h (10.04 m/s)	1.82 J
100 mm	51.07 km/h (14.18 m/s)	3.63 J

Magnetic elements are delicate – a strong collision with metal causes immediate chipping. Watch the impact speed – a magnet released freely turns into a projectile. Kinetic force can trigger coating fragments or dangerous crushing to skin. Always hold the magnet during installation so it doesn't slam with momentum against the steel surface. A collision at high speed almost guarantees destruction of the magnet. Wear eye protection when playing with powerful specimens.

Corrosion warning: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

Contrary to myths, water does not block the magnetic field. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Wall mount (shear)

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

2. Efficiency vs thickness

*Thin steel (e.g. computer case) significantly reduces 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) = 0.22

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 exceptionally strong rod magnet, composed of advanced NdFeB material, which, with dimensions of Ø35x5 mm, guarantees the highest energy density. This specific item features a tolerance of ±0.1mm and professional build quality, making it an excellent solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 9.25 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring lightning-fast order fulfillment. Furthermore, its Ni-Cu-Ni coating effectively protects it against corrosion in typical 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 90.73 N with a weight of only 36.08 g, this rod is indispensable in electronics and wherever every gram matters.

Due to the brittleness of the NdFeB material, you must not use force-fitting (so-called press-fit), as this risks chipping the coating of this precision component. To ensure stability in automation, 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 extreme miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø35x5), 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 35 mm and height 5 mm. The key parameter here is the lifting capacity amounting to approximately 9.25 kg (force ~90.73 N), which, with such compact 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 35 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.

Strengths as well as weaknesses of Nd₂Fe₁₄B magnets.

Strengths

Apart from their superior magnetic energy, neodymium magnets have these key benefits:

Their strength is durable, and after around ten years it drops only by ~1% (theoretically),
They are noted for resistance to demagnetization induced by presence of other magnetic fields,
Thanks to the glossy finish, the coating of Ni-Cu-Ni, gold-plated, or silver-plated gives an elegant appearance,
They are known for high magnetic induction at the operating surface, which improves attraction properties,
Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
Possibility of exact creating and adjusting to individual applications,
Wide application in modern industrial fields – they are commonly used in hard drives, electric drive systems, advanced medical instruments, as well as complex engineering applications.
Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which allows their use in small systems

Cons

What to avoid - cons of neodymium magnets: tips and applications.

Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a special holder, which not only secures them against impacts but also raises their durability
Neodymium 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 advise using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
Limited possibility of creating threads in the magnet and complex forms - preferred is cover - magnet mounting.
Health risk related to microscopic parts of magnets can be dangerous, if swallowed, which becomes key in the context of child health protection. Additionally, small elements of these magnets are able to be problematic in diagnostics medical after entering the body.
With budget limitations the cost of neodymium magnets is economically unviable,

Pull force analysis

Detachment force of the magnet in optimal conditions – what it depends on?

Magnet power was defined for optimal configuration, including:

using a sheet made of low-carbon steel, acting as a magnetic yoke
whose thickness reaches at least 10 mm
with a surface free of scratches
without the slightest clearance between the magnet and steel
under vertical application of breakaway force (90-degree angle)
in stable room temperature

Magnet lifting force in use – key factors

Effective lifting capacity is affected by specific conditions, including (from most important):

Gap (between the magnet and the metal), since even a tiny clearance (e.g. 0.5 mm) can cause a decrease in force by up to 50% (this also applies to paint, corrosion or dirt).
Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
Plate thickness – too thin sheet does not close the flux, causing part of the power to be lost into the air.
Metal type – different alloys reacts the same. High carbon content weaken the attraction effect.
Base smoothness – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
Temperature – heating the magnet causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity was assessed using a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 75%. Additionally, even a slight gap between the magnet and the plate lowers the load capacity.

Safe handling of NdFeB magnets

Skin irritation risks

Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If redness happens, cease handling magnets and wear gloves.

Fire risk

Drilling and cutting of neodymium magnets poses a fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.

Life threat

Individuals with a heart stimulator should keep an safe separation from magnets. The magnetism can stop the functioning of the implant.

Phone sensors

Remember: neodymium magnets produce a field that confuses sensitive sensors. Maintain a separation from your mobile, tablet, and navigation systems.

Magnetic media

Avoid bringing magnets close to a purse, laptop, or screen. The magnetism can destroy these devices and wipe information from cards.

Fragile material

Watch out for shards. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.

Power loss in heat

Keep cool. Neodymium magnets are sensitive to temperature. If you need resistance above 80°C, inquire about special high-temperature series (H, SH, UH).

Bone fractures

Large magnets can smash fingers instantly. Do not put your hand between two attracting surfaces.

Do not underestimate power

Exercise caution. Neodymium magnets act from a distance and connect with massive power, often faster than you can move away.

Product not for children

Neodymium magnets are not suitable for play. Eating a few magnets can lead to them attracting across intestines, which poses a critical condition and necessitates urgent medical intervention.
