Pulling power decreases sharply with every subsequent millimeter of gap. Remember that even a very thin break (e.g., dirt, varnish, rust) strongly reduces the pull force. Neodymiums work strongest in perfect adhesion; gap nullifies the power. Notice how flashily the load capacity plummet, when the magnet does not adhere flatly to the steel surface. When calculating the arrangement, eliminate unnecessary gaps.

The following data defines the theoretical force sufficient to initiate the slippage of the magnet vertically along a vertical steel plate (assuming standard friction). This parameter varies with the distance 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 mounting a element on a vertical wall (e.g., a fridge), it will maintain just approx. 1/5 of its maximum pull force. Gravitational force and a low friction coefficient mean that products slide down easier than they detach. Planning a wall mount? Remember that the shear force is much weaker than the maximum static pull force. On a slippery surface, the magnet will slide down under a much lighter cargo. Using a rubber coating can significantly increase the grip.

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

A thin metal plate is not enough to absorb the entire magnetic field, which weakens actual performance of the magnet. Should you attach a powerful product to a weak sheet, the flux will pass right through and the holding will be smaller. To squeeze the maximum of this neodymium's power, you need a suitably thick element of metal. The saturation phenomenon causes that on thin elements (e.g., appliance housings), the product works worse. We suggest choosing the steel cross-section from these parameters.

Standard neodymium magnets irreversibly lose parameters after exceeding the maximum temperature. Protect against heat – excessive heat can irreversibly demagnetize this magnet. As the temperature rises, the neodymium's power momentarily drops. Avoid using this product near heat sources higher than its working range. Ignoring the limit will cause destruction of magnetism.

*Engineering note: Temperature resistance is determined by both grade, and the Permeance Coefficient Pc. Low-profile magnets (low permeance coefficient) are more susceptible to demagnetization sooner than taller cylinders. The danger warning in the table signals a risk of irreversible loss for this particular item.

Two strong neodymiums interact from a wider radius than a neodymium and metal setup. Such a system of two magnets creates a more powerful interaction and a larger range of operation. Designing a powerful holder? Utilize two neodymiums instead of a neodymium and a striker plate. Be careful that when bringing together two magnets, the pinch force is massive. The levitation is a bit weaker than the connection force, but still impressive.
*Field value in repulsion mode drops to ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
Note: Results apply to sliding force of a pair of identical neodymium magnets (friction ~0.15 for Ni-Ni coating).

A strong magnetic field is a real danger to electronics as well as medical implants. These magnets generate a field that prevents correct functioning of sensitive medical devices. Be aware: the unseen radiation penetrates the body and glass. Increased vigilance must be taken by people with cochlear implants and insulin pumps. Influence will be felt by: automatic timepieces, car keys, speakers, and screens. Do not place the magnet near cards, hard drives, or precise measuring instruments.

Table 8: Collisions (cracking risk) - collision effects

Magnetic elements are prone to chipping – a collision with steel can result in shattering. Control the attraction moment – a magnet released freely becomes dangerous. Striking energy can cause material chips or dangerous crushing to skin. Hold the magnet firmly during mounting so it doesn't hit violently against the metal. A collision at high speed ends with a crack of the neodymium. Use safety goggles when working with powerful specimens.

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

In water, the magnet feels stronger thanks to Archimedes' principle. Buoyancy helps in lifting finds.

1. Wall mount (shear)

*Warning: On a vertical surface, the magnet retains just approx. 20-30% of its max power.

2. Steel saturation

*Thin steel (e.g. computer case) drastically limits 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) = 0.83

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 magnet with a hole MP 5x2.7/1.2x5 Z / N38 is created for mechanical fastening, where glue might fail or be insufficient. Mounting is clean and reversible, unlike gluing. It is also often used in advertising for fixing signs and in workshops for organizing tools.

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 very brittle and inelastic. One turn too many can destroy the magnet, so do it slowly. The flat screw head should evenly press the magnet. Remember: cracking during assembly results from material properties, not a product defect.

These magnets are coated with standard Ni-Cu-Ni plating, which protects them in indoor conditions, but is not sufficient for rain. In the place of the mounting hole, the coating is thinner and can be damaged when tightening the screw, which will become a corrosion focus. If you must use it outside, paint it with anti-corrosion paint after mounting.

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.

This model is characterized by dimensions Ø5x5 mm and a weight of 0.69 g. 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. In the case of connecting two rings, make sure one is turned the right way. When ordering a larger quantity, magnets are usually packed in stacks, where they are already naturally paired.

Strengths and weaknesses of Nd₂Fe₁₄B magnets.

Pros

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

Their strength is maintained, and after around ten years it decreases only by ~1% (theoretically),
They retain their magnetic properties even under external field action,
In other words, due to the smooth layer of nickel, the element becomes visually attractive,
Magnets have exceptionally strong 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 constructing and the capacity to customize to unusual requirements,
Versatile presence in future technologies – they serve a role in magnetic memories, brushless drives, precision medical tools, and industrial machines.
Thanks to their power density, small magnets offer high operating force, with minimal size,

Disadvantages

Disadvantages of NdFeB magnets:

Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a strong case, which not only secures them against impacts but also raises their durability
Neodymium magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop 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
They rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
Due to limitations in producing nuts and complex forms in magnets, we recommend using cover - magnetic mount.
Possible danger to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, small elements of these magnets can be problematic in diagnostics medical in case of swallowing.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Lifting parameters

Maximum lifting capacity of the magnet – what affects it?

Information about lifting capacity was determined for optimal configuration, including:

on a plate made of structural steel, effectively closing the magnetic flux
possessing a massiveness of minimum 10 mm to ensure full flux closure
with an ground touching surface
without any air gap between the magnet and steel
under vertical application of breakaway force (90-degree angle)
at temperature approx. 20 degrees Celsius

Impact of factors on magnetic holding capacity in practice

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

Distance – the presence of any layer (rust, dirt, air) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the nominal value.
Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of generating force.
Steel grade – the best choice is high-permeability steel. Stainless steels may attract less.
Surface condition – ground elements guarantee perfect abutment, which improves field saturation. Rough surfaces weaken the grip.
Temperature influence – high temperature reduces pulling force. Too high temperature can permanently damage the magnet.

Lifting capacity testing was conducted on a smooth plate of suitable thickness, under a perpendicular pulling force, however under parallel forces the holding force is lower. In addition, even a small distance between the magnet and the plate decreases the load capacity.

Safe handling of NdFeB magnets

Product not for children

Neodymium magnets are not suitable for play. Accidental ingestion of multiple magnets can lead to them pinching intestinal walls, which poses a severe health hazard and necessitates immediate surgery.

Life threat

For implant holders: Powerful magnets affect electronics. Maintain minimum 30 cm distance or request help to handle the magnets.

Machining danger

Fire hazard: Rare earth powder is explosive. Do not process magnets without safety gear as this risks ignition.

Caution required

Use magnets consciously. Their powerful strength can surprise even professionals. Be vigilant and respect their force.

Nickel coating and allergies

Medical facts indicate that nickel (the usual finish) is a potent allergen. If you have an allergy, avoid direct skin contact and choose encased magnets.

Magnets are brittle

Neodymium magnets are ceramic materials, meaning they are fragile like glass. Clashing of two magnets leads to them cracking into shards.

GPS Danger

Note: rare earth magnets produce a field that disrupts precision electronics. Keep a safe distance from your mobile, device, and navigation systems.

Bone fractures

Risk of injury: The pulling power is so great that it can cause hematomas, pinching, and broken bones. Protective gloves are recommended.

Power loss in heat

Keep cool. NdFeB magnets are sensitive to temperature. If you require operation above 80°C, inquire about HT versions (H, SH, UH).

Cards and drives

Powerful magnetic fields can corrupt files on payment cards, hard drives, and storage devices. Stay away of at least 10 cm.
