Grip strength decreases significantly per each millimeter of distance. Note that even a microscopic distance (e.g., dirt, paint, dust) significantly weakens the grip. Magnets hold optimally in perfect adhesion; gap weakens the power. See how flashily the load capacity fall, when the product does not adhere tightly to the steel surface. When designing the arrangement, eliminate redundant distances.

This section shows the approximate weight limit sufficient to start the sliding of the magnet vertically along a upright steel wall (assuming standard friction). This value is a function of the separation distance between the magnet and the surface.

Table 3: Wall mounting (shearing) - behavior on slippery surfaces
MP 15x7/3.5x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	1.53 kg / 3.37 LBS 1527.0 g / 15.0 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.02 kg / 2.24 LBS 1018.0 g / 10.0 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.51 kg / 1.12 LBS 509.0 g / 5.0 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	2.55 kg / 5.61 LBS 2545.0 g / 25.0 N

When hanging a element on a upright plane (e.g., a board), it you can count on barely approx. 1/5 of its maximum pull force. Gravitational force and a low friction coefficient cause that holders slip faster than they pull off. Want to create a vertical fastening? Remember that the sliding force is significantly lower than the maximum static pull force. On a smooth steel, the holder will slide down under a much lighter load. Application of an anti-slip layer can significantly raise the stability.

A thin sheet is unable to conduct the full magnetic flux, which squanders power of the magnet. Should you install a neodymium to a too thin substrate, the magnetism 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 saturation phenomenon causes that on delicate walls (e.g., thin profiles), the product works worse. We advise picking the steel thickness from these parameters.

Table 5: Working in heat (stability) - resistance threshold

Standard neodymium magnets lose power after exceeding the maximum temperature. Protect against heat – heat can irreversibly demagnetize this product. As the temperature rises, the neodymium's force momentarily drops. Avoid using this product close to ovens exceeding its working range. Exceeding the critical threshold will cause destruction of magnetism.

*Engineering note: Temperature resistance is determined by both grade, as well as the dimension ratios. Low-profile magnets (low Pc) risk losing magnetic properties at lower temperatures compared to rod magnets. The danger warning in the table points to permanent field degradation for this particular item.

Two magnets attract each other from a much further distance than a neodymium and metal combination. The setup of magnet-to-magnet generates a stronger field and a wider radius of performance. Designing a strong closure? Utilize two neodymiums instead of a neodymium and a steel. Remember that when connecting a pair of magnets, the impact force is extreme. The repulsion force is a bit weaker than the attraction, but still impressive.
*Field value between like poles is approximately ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
Note: Calculations show sliding force of a pair of same neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

Table 7: Safety (HSE) (implants) - precautionary measures

A strong magnetic field is a serious hazard to IT equipment and pacemakers. These NdFeB products produce a flux that disrupts operation of sensitive medical devices. Notice: the invisible magnetic field passes through tissues and housings. Increased vigilance must be exercised by people with hearing aids and insulin pumps. Influence will be felt by: mechanical watches, remotes, speakers, and displays. Do not bring the product near payment cards, hard drives, or sensitive navigation tools.

Table 8: Impact energy (kinetic energy) - warning
MP 15x7/3.5x5 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	29.26 km/h (8.13 m/s)	0.21 J
30 mm	49.78 km/h (13.83 m/s)	0.60 J
50 mm	64.25 km/h (17.85 m/s)	1.00 J
100 mm	90.87 km/h (25.24 m/s)	2.00 J

NdFeB products are delicate – a collision with steel causes immediate chipping. Pay attention to connection velocity – a magnet released freely turns into a projectile. Striking energy can trigger coating fragments or injury to fingers. Always hold the magnet during installation so it doesn't hit violently against the metal. A collision at high speed almost guarantees destruction of the magnet. Wear eye protection when working with large magnets.

Rust risk: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

Water displaces steel, making heavy objects slightly lighter. However, remember the water resistance when pulling the rope quickly.

1. Wall mount (shear)

*Caution: On a vertical wall, the magnet holds merely approx. 20-30% of its max power.

2. Efficiency vs thickness

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

3. Heat tolerance

*For N38 material, 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) = 0.39

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.

It is ideally suited for places where solid attachment of the magnet to the substrate is required without the risk of detachment. 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 5.09 kg works great as a cabinet closure, speaker holder, or mounting element in devices.

This material behaves more like porcelain than steel, so it doesn't forgive mistakes during mounting. When tightening the screw, you must maintain great sensitivity. We recommend tightening manually with a screwdriver, not an impact driver, because too much pressure 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.

These magnets are coated with standard Ni-Cu-Ni plating, which protects them in indoor conditions, but is not sufficient for rain. 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.

A screw or bolt with a thread diameter smaller than 7/3.5 mm fits this model. For magnets with a straight hole, a conical head can act like a wedge and burst the magnet. Aesthetic mounting requires selecting the appropriate head size.

The presented product is a ring magnet with dimensions Ø15 mm (outer diameter) and height 5 mm. The key parameter here is the holding force amounting to approximately 5.09 kg (force ~49.95 N). The product has a [NiCuNi] coating and is made of NdFeB material. Inner hole dimension: 7/3.5 mm.

The poles are located on the planes with holes, not on the sides of the ring. 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). When ordering a larger quantity, magnets are usually packed in stacks, where they are already naturally paired.

Strengths as well as weaknesses of neodymium magnets.

Strengths

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

They virtually do not lose strength, because even after ten years the performance loss is only ~1% (in laboratory conditions),
They have excellent resistance to magnetism drop due to opposing magnetic fields,
The use of an aesthetic coating of noble metals (nickel, gold, silver) causes the element to have aesthetics,
They feature high magnetic induction at the operating surface, which increases their power,
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...
Considering the possibility of precise shaping and customization to individualized needs, magnetic components can be created in a variety of geometric configurations, which expands the range of possible applications,
Fundamental importance in advanced technology sectors – they serve a role in HDD drives, drive modules, diagnostic systems, as well as complex engineering applications.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Cons

Disadvantages of neodymium magnets:

Brittleness is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a strong case, which not only protects them against impacts but also raises 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.
When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
Limited ability of making nuts in the magnet and complicated forms - recommended is cover - magnet mounting.
Potential hazard resulting from small fragments of magnets are risky, when accidentally swallowed, which gains importance in the context of child safety. It is also worth noting that small components of these products can disrupt the diagnostic process medical after entering the body.
With large orders the cost of neodymium magnets is a challenge,

Lifting parameters

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

Breakaway force is the result of a measurement for the most favorable conditions, taking into account:

using a base made of mild steel, serving as a ideal flux conductor
whose thickness reaches at least 10 mm
characterized by even structure
without the slightest insulating layer between the magnet and steel
during pulling in a direction perpendicular to the mounting surface
at ambient temperature approx. 20 degrees Celsius

Practical lifting capacity: influencing factors

Holding efficiency is influenced by specific conditions, including (from most important):

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.
Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
Plate material – mild steel gives the best results. Higher carbon content lower magnetic properties and holding force.
Surface finish – ideal contact is obtained only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
Temperature – heating the magnet results in weakening of induction. Check the thermal limit for a given model.

Lifting capacity was measured using a smooth steel plate of suitable thickness (min. 20 mm), under vertically applied force, however under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate lowers the holding force.

H&S for magnets

Crushing force

Big blocks can break fingers instantly. Do not place your hand betwixt two attracting surfaces.

Thermal limits

Watch the temperature. Exposing the magnet above 80 degrees Celsius will destroy its magnetic structure and pulling force.

GPS Danger

A powerful magnetic field disrupts the operation of compasses in phones and GPS navigation. Maintain magnets close to a smartphone to avoid damaging the sensors.

Threat to electronics

Data protection: Neodymium magnets can ruin data carriers and sensitive devices (pacemakers, medical aids, mechanical watches).

Metal Allergy

Some people have a hypersensitivity to Ni, which is the typical protective layer for neodymium magnets. Prolonged contact might lead to dermatitis. We strongly advise use safety gloves.

Implant safety

Medical warning: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.

Handling guide

Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Be predictive.

Protective goggles

Beware of splinters. Magnets can explode upon violent connection, launching sharp fragments into the air. Wear goggles.

Mechanical processing

Dust created during cutting of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.

Choking Hazard

These products are not suitable for play. Swallowing multiple magnets may result in them attracting across intestines, which poses a direct threat to life and requires immediate surgery.
