Pulling power drops sharply with every mm of gap. Remember that even a very thin break (e.g., contamination, varnish, dust) noticeably diminishes the holding power. Magnetic products work most effectively at the point of direct contact; gap drastically cuts the power. See how quickly the parameters plummet, when the product does not adhere tightly to the steel surface. When designing the arrangement, discard additional spacers.

The table below defines the approximate holding capacity required to start the shifting of the magnet vertically against a vertical steel plate (assuming typical friction). The holding force varies with the distance between the magnet and the surface.

Table 3: Wall mounting (sliding) - vertical pull
MW 12x4 / N52

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	1.40 kg / 3.10 LBS 1404.0 g / 13.8 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.94 kg / 2.06 LBS 936.0 g / 9.2 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.47 kg / 1.03 LBS 468.0 g / 4.6 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	2.34 kg / 5.16 LBS 2340.0 g / 23.0 N

When mounting a element on a vertical wall (e.g., a car body), it will maintain only approx. 1/5 of its nominal power. Gravity as well as a low friction coefficient cause that holders slide down faster than they pull off. Designing a wall mount? Remember that the shear force is significantly lower than the perpendicular breakaway force. On a painted metal, the magnet will slide down under a much lighter cargo. Utilizing a rubberized layer can significantly increase the grip.

A too thin steel is not enough to conduct the entire magnetic field, which squanders power of the holder. Should you attach a powerful product to a weak sheet, the field will penetrate right through and the holding will be smaller. To squeeze the maximum of this neodymium's potential, you require a sufficiently solid backing of steel. The material oversaturation causes that on sheet metal structures (e.g., thin profiles), the product holds weaker. We recommend selecting the steel thickness according to the table below.

Standard neodymium magnets change their properties parameters past the thermal threshold. Protect against heat – excessive heat can permanently destroy this magnet. With increasing heat, the neodymium's capacity momentarily decreases. Refrain from using this magnet in hot environments exceeding its safe range. Exceeding the critical threshold will cause irreversible degradation of magnetic properties.

*Technical advisory: Temperature resistance is determined by both grade, as well as the dimension ratios. Thin magnets (low Pc) risk losing magnetic properties under lower heat stress compared to rod magnets. The danger warning in the table points to permanent field degradation for this specific geometry.

Two strong neodymiums interact from a significantly greater distance than a magnet and sheet setup. The connection of two magnets generates a stronger field and a larger range of operation. Designing a powerful holder? Apply two magnets instead of one magnet and a steel. Be careful that when connecting a pair of magnets, the impact force is huge. The repulsion force is a bit weaker than the attraction, but still significant.
*Flux density in repulsion mode is approximately ~0 Gs in the exact middle of the gap (due to field cancellation).
* Figures refer to shear force of two identical magnets (friction coefficient ~0.15 for Ni-Ni coating).

Powerful magnet radiation poses a large risk to IT equipment as well as medical implants. These neodymiums generate a flux that prevents correct functioning of sensitive medical devices. Be aware: the unseen radiation passes through tissues and housings. Increased vigilance must be exercised by people with hearing aids and drug dispensers. Influence will be felt by: mechanical watches, car keys, speakers, and displays. Avoid contact with magnetic cards, HDD media, or sensitive navigation tools.

Magnetic elements are prone to chipping – a violent impact against metal risks their cracking. Control the attraction moment – a neodymium left loose turns into a projectile. Impact energy can trigger coating fragments or painful pinches to skin. Always hold the magnet during mounting so it doesn't hit with great force against the metal. A collision at high speed ends with a crack of the neodymium. Wear eye protection when playing with powerful specimens.

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

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. Shear force

*Note: On a vertical surface, the magnet retains just approx. 20-30% of its perpendicular strength.

2. Efficiency vs thickness

*Thin metal sheet (e.g. 0.5mm PC case) significantly weakens the holding force.

3. Thermal stability

*For standard magnets, 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 offered product is an extremely powerful rod magnet, manufactured from durable NdFeB material, which, with dimensions of Ø12x4 mm, guarantees maximum efficiency. This specific item is characterized by high dimensional repeatability and professional build quality, making it an excellent solution for the most demanding engineers and designers. As a magnetic rod with impressive force (approx. 4.68 kg), this product is available off-the-shelf from our European logistics center, ensuring quick order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

It successfully proves itself in modeling, advanced automation, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 45.89 N with a weight of only 3.39 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 do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.

Magnets NdFeB grade N38 are suitable 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 (Ø12x4), 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 12 mm and height 4 mm. The value of 45.89 N means that the magnet is capable of holding a weight many times exceeding its own mass of 3.39 g. The product has a [NiCuNi] coating, which secures it against oxidation, 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 12 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 neodymium magnets.

Advantages

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

They do not lose power, even after approximately 10 years – the drop in power is only ~1% (theoretically),
Neodymium magnets are exceptionally resistant to demagnetization caused by external field sources,
Thanks to the shimmering finish, the coating of nickel, gold-plated, or silver gives an professional appearance,
Magnetic induction on the top side of the magnet remains strong,
Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for operation at temperatures approaching 230°C and above...
Thanks to modularity in constructing and the capacity to customize to specific needs,
Significant place in innovative solutions – they are utilized in mass storage devices, drive modules, diagnostic systems, as well as multitasking production systems.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which makes them useful in small systems

Cons

Disadvantages of neodymium magnets:

To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
Limited ability of creating nuts in the magnet and complex forms - recommended is casing - mounting mechanism.
Potential hazard resulting from small fragments of magnets are risky, in case of ingestion, which gains importance in the aspect of protecting the youngest. Additionally, small elements of these products can disrupt the diagnostic process medical in case of swallowing.
Due to complex production process, their price is higher than average,

Pull force analysis

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

Information about lifting capacity was defined for ideal contact conditions, assuming:

with the contact of a sheet made of low-carbon steel, ensuring full magnetic saturation
whose thickness equals approx. 10 mm
characterized by even structure
without any insulating layer between the magnet and steel
during pulling in a direction vertical to the plane
at temperature approx. 20 degrees Celsius

Key elements affecting lifting force

Effective lifting capacity is affected by working environment parameters, mainly (from priority):

Clearance – existence of any layer (paint, tape, gap) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
Direction of force – highest force is obtained only during perpendicular pulling. The force required to slide of the magnet along the plate is usually many times smaller (approx. 1/5 of the lifting capacity).
Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
Steel type – low-carbon steel attracts best. Alloy steels decrease magnetic permeability and lifting capacity.
Surface condition – ground elements guarantee perfect abutment, which increases field saturation. Rough surfaces 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 testing was carried out on a smooth plate of optimal thickness, under perpendicular forces, in contrast under parallel forces the load capacity is reduced by as much as fivefold. In addition, even a slight gap between the magnet and the plate reduces the load capacity.

Precautions when working with neodymium magnets

Avoid contact if allergic

Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If an allergic reaction occurs, immediately stop working with magnets and wear gloves.

Cards and drives

Avoid bringing magnets close to a purse, computer, or screen. The magnetism can irreversibly ruin these devices and erase data from cards.

Warning for heart patients

Warning for patients: Powerful magnets disrupt electronics. Keep minimum 30 cm distance or ask another person to work with the magnets.

Precision electronics

Remember: neodymium magnets generate a field that interferes with sensitive sensors. Keep a safe distance from your mobile, tablet, and navigation systems.

Keep away from children

Always store magnets away from children. Risk of swallowing is significant, and the effects of magnets clamping inside the body are fatal.

Material brittleness

Despite the nickel coating, the material is delicate and cannot withstand shocks. Do not hit, as the magnet may shatter into hazardous fragments.

Flammability

Drilling and cutting of NdFeB material carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is difficult to extinguish.

Operating temperature

Monitor thermal conditions. Exposing the magnet to high heat will permanently weaken its magnetic structure and pulling force.

Caution required

Handle magnets with awareness. Their powerful strength can shock even professionals. Plan your moves and do not underestimate their force.

Finger safety

Large magnets can smash fingers in a fraction of a second. Under no circumstances place your hand between two attracting surfaces.
