Magnetic force decreases sharply with every subsequent millimeter of gap. Keep in mind that every additional insulation layer (e.g., contamination, varnish, veneer) noticeably reduces the pull force. Magnets hold most effectively at the point of direct contact; air break kills the force. See how rapidly the parameters plummet, when the product does not adhere directly to the steel surface. When planning the assembly, avoid unnecessary gaps.

The table below indicates the estimated weight limit necessary to initiate the shifting of the magnet down on a vertical steel wall (assuming typical friction coefficient). This value is a function of the distance between the magnet and the surface.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MP 12x8/4x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.66 kg / 663.0 g 6.5 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.44 kg / 442.0 g 4.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.22 kg / 221.0 g 2.2 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.11 kg / 1105.0 g 10.8 N

When hanging a magnet on a vertical wall (e.g., a board), it will maintain barely about 20%-30% of its nominal power. Gravity and a weak degree of grip cause that products move down easier than they pull off. Want to create a wall mount? Remember that the shear force is significantly lower than the maximum static pull force. On a painted metal, the magnet will give way down under a noticeably lighter load. Application of an anti-slip pad can drastically raise the stability.

Table 4: Steel thickness (substrate influence) - sheet metal selection
MP 12x8/4x3 / N38

Steel thickness (mm)	% power	Real pull force (kg)
0.5 mm	10%	0.22 kg / 221.0 g 2.2 N
1 mm	25%	0.55 kg / 552.5 g 5.4 N
2 mm	50%	1.11 kg / 1105.0 g 10.8 N
5 mm	100%	2.21 kg / 2210.0 g 21.7 N
10 mm	100%	2.21 kg / 2210.0 g 21.7 N

A thin sheet is not enough to conduct the full magnetic flux, which squanders power of the magnet. If you attach a powerful product to a thin surface, the magnetism will pass right through and the pull force will drop sharply. To squeeze the maximum of this magnet's potential, you require a sufficiently solid piece of steel. The material oversaturation causes that on sheet metal structures (e.g., appliance housings), the product works worse. We advise picking the steel thickness based on the following data.

Table 5: Thermal stability (stability) - resistance threshold

40 °C	-2.2%	2.16 kg / 2161.4 g 21.2 N	OK
60 °C	-4.4%	2.11 kg / 2112.8 g 20.7 N
80 °C	-6.6%	2.06 kg / 2064.1 g 20.2 N
100 °C	-28.8%	1.57 kg / 1573.5 g 15.4 N

Standard neodymium magnets change their properties parameters after exceeding the maximum temperature. Avoid high temperatures – high temperature can irreversibly damage this product. As the temperature rises, the neodymium's capacity momentarily lowers. Refrain from using this magnet close to ovens higher than its operating temperature limit. Too high temperature will cause destruction of magnetism.

*Technical advisory: Temperature resistance depends not only on the material grade, and the Permeance Coefficient Pc. Low-profile magnets (low Pc) risk losing magnetic properties at lower temperatures compared to rod magnets. Red status in the table points to permanent field degradation for this particular item.

Two strong neodymiums attract each other from a much further distance than a magnet and steel setup. Such a system of magnet-to-magnet creates a more powerful interaction and a wider radius of action. Designing a solid fastener? Apply two magnets instead of a neodymium and a striker plate. Be careful that when connecting a pair of magnets, the impact force is massive. The repulsion force is slightly lower than the attraction, but still large.
*Flux density in repulsion mode reaches ~0 Gs in the exact middle of the gap (caused by magnetic field nullification).

Powerful magnet radiation is a real danger to IT equipment as well as medical implants. These magnets generate a field that prevents correct functioning of digital equipment. Be aware: the unseen radiation acts through matter and plastic. Increased vigilance must be exercised by people with hearing aids and drug dispensers. The risk also applies to: mechanical watches, car keys, speakers, and screens. Do not bring the product near payment cards, HDD media, or precise measuring instruments.

Magnetic elements are delicate – a violent impact against metal risks their cracking. Watch the impact speed – a neodymium left loose turns into a projectile. Striking energy can trigger coating fragments or painful pinches to skin. Always hold the magnet during installation so it doesn't slam with momentum against the metal. A collision at high speed ends with a crack of the neodymium. Use safety goggles when working with large magnets.

Environment	Effective steel pull	Effect
Air (land)	2.21 kg	Standard
Water (riverbed)	2.53 kg (+0.32 kg Buoyancy gain)	+14.5%

Rust risk: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

Contrary to myths, water does not block the magnetic field. Buoyancy helps in lifting finds.

1. Vertical hold

*Warning: On a vertical wall, the magnet retains merely approx. 20-30% of its nominal pull.

2. Steel saturation

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

3. Power loss vs temp

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.32

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 ring-shaped magnet MP 12x8/4x3 / N38 is created for mechanical fastening, where glue might fail or be insufficient. Thanks to the hole (often for a screw), this model enables easy screwing to wood, wall, plastic, or metal. It is also often used in advertising for fixing signs and in workshops for organizing tools.

This material behaves more like porcelain than steel, so it doesn't forgive mistakes during mounting. One turn too many can destroy the magnet, so do it slowly. It's a good idea to use a flexible washer under the screw head, which will cushion the stresses. Remember: cracking during assembly results from material properties, not a product defect.

Moisture can penetrate micro-cracks in the coating and cause oxidation of the magnet. Damage to the protective layer during assembly is the most common cause of rusting. If you must use it outside, paint it with anti-corrosion paint after mounting.

The inner hole diameter determines the maximum size of the mounting element. If the magnet does not have a chamfer (cone), we recommend using a screw with a flat or cylindrical head, or possibly using a washer. Aesthetic mounting requires selecting the appropriate head size.

It is a magnetic ring with a diameter of 12 mm and thickness 3 mm. The pulling force of this model is an impressive 2.21 kg, which translates to 21.72 N in newtons. The mounting hole diameter is precisely 8/4 mm.

The poles are located on the planes with holes, not on the sides of the ring. In the case of connecting two rings, make sure one is turned the right way. We do not offer paired sets with marked poles in this category, but they are easy to match manually.

Advantages as well as disadvantages of neodymium magnets.

Pros

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

They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (in laboratory conditions),
They feature excellent resistance to magnetism drop when exposed to external magnetic sources,
In other words, due to the glossy layer of nickel, the element becomes visually attractive,
Magnetic induction on the working layer of the magnet turns out to be strong,
Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
Possibility of detailed modeling as well as adjusting to individual conditions,
Huge importance in electronics industry – they find application in hard drives, electric drive systems, medical equipment, as well as industrial machines.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which enables their usage in miniature devices

Disadvantages

Disadvantages of neodymium magnets:

Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a special holder, which not only secures them against impacts but also increases their durability
We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
They oxidize in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
Limited possibility of making nuts in the magnet and complicated shapes - recommended is a housing - mounting mechanism.
Health risk related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Additionally, small components of these magnets are able to disrupt the diagnostic process medical when they are in the body.
High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities

Pull force analysis

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

The specified lifting capacity represents the peak performance, measured under laboratory conditions, specifically:

on a base made of mild steel, effectively closing the magnetic flux
whose thickness reaches at least 10 mm
characterized by smoothness
under conditions of ideal adhesion (surface-to-surface)
during pulling in a direction perpendicular to the mounting surface
in neutral thermal conditions

Determinants of lifting force in real conditions

During everyday use, the real power results from many variables, ranked from most significant:

Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
Load vector – highest force is reached only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is standardly many times smaller (approx. 1/5 of the lifting capacity).
Substrate thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
Material type – ideal substrate is high-permeability steel. Hardened steels may have worse magnetic properties.
Surface quality – the more even the surface, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
Thermal factor – hot environment reduces magnetic field. Too high temperature can permanently damage the magnet.

Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under shearing force the lifting capacity is smaller. In addition, even a slight gap between the magnet and the plate decreases the load capacity.

Warnings

Electronic hazard

Device Safety: Neodymium magnets can ruin payment cards and delicate electronics (heart implants, medical aids, timepieces).

Magnet fragility

Watch out for shards. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. Wear goggles.

Danger to the youngest

Strictly store magnets away from children. Choking hazard is high, and the consequences of magnets connecting inside the body are tragic.

Do not overheat magnets

Avoid heat. Neodymium magnets are susceptible to heat. If you require operation above 80°C, look for HT versions (H, SH, UH).

GPS and phone interference

Navigation devices and smartphones are highly sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can ruin the internal compass in your phone.

Finger safety

Large magnets can break fingers in a fraction of a second. Do not place your hand between two strong magnets.

Safe operation

Use magnets consciously. Their immense force can shock even experienced users. Be vigilant and do not underestimate their power.

Implant safety

Warning for patients: Powerful magnets affect electronics. Keep at least 30 cm distance or request help to work with the magnets.

Fire risk

Mechanical processing of neodymium magnets carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.

Allergy Warning

Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If redness occurs, immediately stop handling magnets and use protective gear.
