Pulling power weakens significantly per each millimeter of spacing. Keep in mind that even a microscopic distance (e.g., contamination, varnish, rust) strongly weakens the grip. Magnets operate most effectively in perfect adhesion; gap weakens the power. Notice how quickly the load capacity fall, when the magnet does not adhere flatly to the metal substrate. When designing the assembly, discard additional spacers.

The following data presents the estimated weight limit required to cause the downward movement of the magnet downwards along a upright metal surface (assuming typical friction coefficient). This value varies with the air gap between the magnet and the surface.

Table 3: Wall mounting (shearing) - behavior on slippery surfaces
MP 5x2.7/1.2x5 Z / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.22 kg / 0.50 pounds 225.0 g / 2.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.15 kg / 0.33 pounds 150.0 g / 1.5 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.08 kg / 0.17 pounds 75.0 g / 0.7 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.38 kg / 0.83 pounds 375.0 g / 3.7 N

When placing a holder on a upright plane (e.g., a fridge), it you can count on barely about 1/5 of nominal attraction strength. Gravity and a low friction coefficient mean that products slide down easier than they pull off. Designing a vertical fastening? Remember that the shear force is noticeably lower than the maximum static pull force. On a painted metal, the holder will slip down under a noticeably lighter cargo. Utilizing a rubberized layer can significantly raise the stability.

12 mm	100%	0.75 kg / 1.65 pounds 750.0 g / 7.4 N

A thin sheet is incapable of take in the full magnetic flux, which wastes potential of the magnet. If you attach a powerful product to a thin surface, the field will penetrate right through and the attraction force will be weaker. To utilize the maximum of this neodymium's potential, you need a suitably thick element of steel. The material oversaturation means that on delicate walls (e.g., thin profiles), the product shows lower pull force. We recommend selecting the steel dimension from these parameters.

Standard neodymium magnets irreversibly lose parameters after exceeding the maximum temperature. Watch out for overheating – high temperature can irreversibly demagnetize this product. With increasing heat, the magnet's capacity temporarily drops. Do not use this product near heat sources exceeding its operating temperature limit. Ignoring the limit will lead to permanent loss of magnetism.

*Important note: Heat tolerance is determined by both grade, but also on the magnet's shape. Thin magnets (pancake types) risk losing magnetic properties sooner compared to rod magnets. The danger warning in the table points to a risk of irreversible loss for this particular item.

Two magnets attract each other from a significantly greater distance than a neodymium and metal setup. Such a system of two magnets creates a more powerful interaction and a larger range of performance. Designing a powerful holder? Utilize two neodymiums instead of a neodymium and a striker plate. Remember that when bringing together two magnets, the impact force is huge. The repulsion force is marginally weaker than the connection force, but still impressive.
*Flux density between like poles reaches ~0 Gs at the midpoint of the gap (due to field cancellation).
* Estimates apply to shear force of two identical neodymium magnets (friction ~0.15 for Ni-Ni plating).

Table 7: Hazards (implants) - warnings

A strong magnetic field is a serious hazard to electronics and pacemakers. These magnets generate a field that prevents correct functioning of digital equipment. Notice: the invisible magnetic field acts through matter and housings. Exceptional care must be exercised by people with hearing aids and drug dispensers. Also at risk are: automatic timepieces, car keys, membranes, and displays. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

MP 5x2.7/1.2x5 Z / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	33.26 km/h (9.24 m/s)	0.03 J
30 mm	57.59 km/h (16.00 m/s)	0.09 J

100 mm	105.14 km/h (29.21 m/s)	0.29 J

NdFeB products are prone to chipping – a violent impact against metal risks their cracking. Watch the impact speed – a magnet released freely turns into a projectile. Striking energy can cause material chips or injury to skin. Always hold the magnet during mounting so it doesn't hit with great force against the metal. A collision at high speed almost guarantees destruction of the magnet. Wear safety glasses when playing with powerful specimens.

The magnetic field penetrates through water without any losses. However, remember the water resistance when pulling the rope quickly.

1. Sliding resistance

*Note: On a vertical surface, the magnet retains merely a fraction of its nominal pull.

2. Efficiency vs thickness

*Thin steel (e.g. 0.5mm PC case) severely weakens the holding force.

3. Power loss vs temp

*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) = 0.83

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 ring-shaped magnet MP 5x2.7/1.2x5 Z / N38 is created for mechanical fastening, where glue might fail or be insufficient. Thanks to the hole (often for a screw), this model enables quick installation to wood, wall, plastic, or metal. This product with a force of 0.75 kg works great as a door latch, speaker holder, or mounting element in devices.

This is a crucial issue when working with model MP 5x2.7/1.2x5 Z / N38. Neodymium magnets are sintered ceramics, which means they are hard but breakable and inelastic. When tightening the screw, you must maintain great sensitivity. We recommend tightening manually with a screwdriver, not an impact driver, because excessive force will cause the ring to crack. 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. This product is dedicated for inside building use. For outdoor applications, we recommend choosing rubberized holders or additional protection with varnish.

A screw or bolt with a thread diameter smaller than 2.7/1.2 mm fits this model. 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.

The presented product is a ring magnet with dimensions Ø5 mm (outer diameter) and height 5 mm. The pulling force of this model is an impressive 0.75 kg, which translates to 7.31 N in newtons. The product has a [NiCuNi] coating and is made of NdFeB material. Inner hole dimension: 2.7/1.2 mm.

These magnets are magnetized axially (through the thickness), which means one flat side is the N pole and the other is S. If you want two such magnets screwed with cones facing each other (faces) to attract, you must connect them with opposite poles (N to S). We do not offer paired sets with marked poles in this category, but they are easy to match manually.

Advantages and disadvantages of rare earth magnets.

Benefits

Besides their high retention, neodymium magnets are valued for these benefits:

They retain full power for almost 10 years – the drop is just ~1% (based on simulations),
They possess excellent resistance to magnetic field loss as a result of opposing magnetic fields,
In other words, due to the metallic surface of gold, the element is aesthetically pleasing,
Magnets have excellent magnetic induction on the active area,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
Thanks to freedom in shaping and the capacity to adapt to unusual requirements,
Fundamental importance in modern technologies – they find application in computer drives, drive modules, medical devices, as well as industrial machines.
Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,

Limitations

Drawbacks and weaknesses of neodymium magnets and ways of using them

They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
We recommend casing - magnetic mount, due to difficulties in producing nuts inside the magnet and complex shapes.
Potential hazard related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, tiny parts of these magnets can disrupt the diagnostic process medical after entering the body.
With budget limitations the cost of neodymium magnets can be a barrier,

Pull force analysis

Maximum lifting force for a neodymium magnet – what affects it?

The specified lifting capacity refers to the peak performance, recorded under ideal test conditions, specifically:

using a plate made of mild steel, serving as a circuit closing element
whose transverse dimension is min. 10 mm
characterized by smoothness
without any clearance between the magnet and steel
during pulling in a direction perpendicular to the plane
at ambient temperature room level

Magnet lifting force in use – key factors

Effective lifting capacity impacted by working environment parameters, including (from most important):

Space between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
Chemical composition of the base – low-carbon steel gives the best results. Higher carbon content decrease magnetic properties and holding force.
Surface condition – smooth surfaces guarantee perfect abutment, which improves field saturation. Uneven metal weaken the grip.
Temperature – heating the magnet results in weakening of induction. It is worth remembering the thermal limit for a given model.

Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under perpendicular forces, whereas under shearing force the load capacity is reduced by as much as fivefold. Moreover, even a small distance between the magnet’s surface and the plate lowers the lifting capacity.

H&S for magnets

Conscious usage

Handle magnets consciously. Their huge power can surprise even experienced users. Be vigilant and do not underestimate their force.

Health Danger

For implant holders: Strong magnetic fields disrupt electronics. Maintain at least 30 cm distance or request help to handle the magnets.

Precision electronics

Note: neodymium magnets produce a field that interferes with precision electronics. Maintain a separation from your phone, device, and GPS.

Combustion hazard

Powder generated during cutting of magnets is combustible. Do not drill into magnets unless you are an expert.

Warning for allergy sufferers

Certain individuals suffer from a contact allergy to nickel, which is the standard coating for neodymium magnets. Extended handling might lead to dermatitis. It is best to use safety gloves.

Shattering risk

Despite metallic appearance, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.

Operating temperature

Regular neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. This process is irreversible.

Threat to electronics

Very strong magnetic fields can erase data on credit cards, hard drives, and storage devices. Stay away of at least 10 cm.

Adults only

Only for adults. Small elements can be swallowed, leading to intestinal necrosis. Store away from children and animals.

Serious injuries

Pinching hazard: The attraction force is so great that it can cause hematomas, crushing, and broken bones. Protective gloves are recommended.
