Grip strength drops drastically with every subsequent millimeter of spacing. Remember that every additional insulation layer (e.g., contamination, varnish, dust) strongly diminishes the holding power. Neodymiums operate most effectively during direct contact; distance nullifies the power. Notice how rapidly the parameters plummet, when the product does not adhere directly to the steel surface. When planning the arrangement, discard additional spacers.

The table below indicates the theoretical weight limit necessary to cause the shifting of the magnet down against a vertical steel wall (assuming standard friction coefficient). This value varies with the distance between the magnet and the metal.

Table 3: Wall mounting (shearing) - behavior on slippery surfaces
MPL 20x8x6 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	1.88 kg / 4.15 LBS 1881.0 g / 18.5 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.25 kg / 2.76 LBS 1254.0 g / 12.3 N

Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	3.14 kg / 6.91 LBS 3135.0 g / 30.8 N

When hanging a magnet on a upright surface (e.g., a car body), it will only hold just about 20%-30% of its nominal power. Gravitational force as well as a low friction coefficient cause that holders move down faster than they pull off. Designing a vertical fastening? Remember that the shear force is significantly lower than the maximum static pull force. On a smooth steel, the holder will slide down under a noticeably lighter load. Utilizing a rubberized layer can drastically increase the grip.

A thin metal plate is unable to conduct the full magnetic flux, which squanders power of the holder. Should you mount a strong magnet to a weak sheet, the flux will pass right through and the pull force will drop sharply. To squeeze the maximum of this magnet's power, you require a sufficiently solid element of steel. The saturation phenomenon causes that on delicate walls (e.g., car bodies), the product shows lower pull force. We advise picking the steel cross-section according to the table below.

Classic neodymiums change their properties power past the thermal threshold. Avoid high temperatures – excessive heat can irreversibly destroy this magnet. With every degree above norm, the neodymium's power briefly lowers. Avoid using this product in hot environments exceeding its operating temperature limit. Ignoring the limit will lead to destruction of magnetism.

*Technical advisory: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Thin magnets (pancake types) risk losing magnetic properties sooner compared to rod magnets. Warning indicator in the table points to permanent field degradation for this specific geometry.

Two strong neodymiums attract each other from a much further distance than a magnet and steel setup. The connection of two magnets creates a more powerful interaction and a larger range of operation. Designing a solid fastener? Use a pair of magnets instead of one magnet and a steel. Exercise caution that when bringing together two magnets, the impact force is huge. The repulsion force is a bit weaker than the connection force, but still impressive.
*The magnetic induction in repulsion mode drops to ~0 Gs at the midpoint between the magnets (due to field cancellation).
Important: Results refer to shear force of a pair of matching magnets (friction coefficient ~0.15 for Ni-Ni coating).

Powerful magnet radiation poses a real danger to electronic devices and pacemakers. These NdFeB products generate a flux that destroys function of sensitive medical devices. Be aware: the unseen radiation acts through matter and plastic. Increased vigilance must be taken by people with hearing aids and insulin pumps. Influence will be felt by: mechanical watches, car keys, speakers, and displays. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Neodymium magnets are prone to chipping – a violent impact against metal causes immediate chipping. Control the attraction moment – a magnet released freely turns into a projectile. Striking energy can trigger coating fragments or dangerous crushing to fingers. Hold the magnet firmly during mounting so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h means shattering of the magnet. Wear eye protection when working with large magnets.

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

Contrary to myths, water does not block the magnetic field. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Sliding resistance

*Note: On a vertical surface, the magnet holds merely approx. 20-30% of its nominal pull.

2. Steel thickness impact

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

3. Heat tolerance

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.52

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.

SMZR 25x150 / N52 - magnetic separator with handle

430.50 ZŁ brutto / pcs

Model MPL 20x8x6 / N38 features a flat shape and industrial pulling force, making it an ideal solution for building separators and machines. As a magnetic bar with high power (approx. 6.27 kg), this product is available immediately from our warehouse in Poland. The durable anti-corrosion layer ensures a long lifespan in a dry environment, protecting the core from oxidation.

The key to success is shifting the magnets along their largest connection plane (using e.g., the edge of a table), which is easier than trying to tear them apart directly. To separate the MPL 20x8x6 / N38 model, firmly slide one magnet over the edge of the other until the attraction force decreases. We recommend care, because after separation, the magnets may want to violently snap back together, which threatens pinching the skin. Using a screwdriver risks destroying the coating and permanently cracking the magnet.

They constitute a key element in the production of wind generators and material handling systems. They work great as invisible mounts under tiles, wood, or glass. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.

For mounting flat magnets MPL 20x8x6 / N38, we recommend utilizing strong epoxy glues (e.g., UHU Endfest, Distal), which ensure a durable bond with metal or plastic. Double-sided tape cushions vibrations, which is an advantage when mounting in moving elements. Remember to roughen and wash the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

The magnetic axis runs through the shortest dimension, which is typical for gripper magnets. Thanks to this, it works best when "sticking" to sheet metal or another magnet with a large surface area. Such a pole arrangement ensures maximum holding capacity when pressing against the sheet, creating a closed magnetic circuit.

This model is characterized by dimensions 20x8x6 mm, which, at a weight of 7.2 g, makes it an element with impressive energy density. It is a magnetic block with dimensions 20x8x6 mm and a self-weight of 7.2 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Strengths and weaknesses of neodymium magnets.

Advantages

Besides their stability, neodymium magnets are valued for these benefits:

They retain attractive force for almost ten years – the drop is just ~1% (according to analyses),
They have excellent resistance to magnetic field loss as a result of external fields,
In other words, due to the shiny layer of nickel, the element looks attractive,
The surface of neodymium magnets generates a concentrated magnetic field – this is a key feature,
Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
Possibility of exact forming and modifying to complex needs,
Wide application in high-tech industry – they find application in mass storage devices, brushless drives, diagnostic systems, as well as other advanced devices.
Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,

Limitations

What to avoid - cons of neodymium magnets: application proposals

At strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
We suggest a housing - magnetic holder, due to difficulties in producing threads inside the magnet and complicated shapes.
Potential hazard related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child health protection. It is also worth noting that small components of these devices are able to be problematic in diagnostics medical in case of swallowing.
Due to complex production process, their price exceeds standard values,

Holding force characteristics

Magnetic strength at its maximum – what affects it?

Magnet power was defined for optimal configuration, including:

using a base made of high-permeability steel, acting as a circuit closing element
with a cross-section minimum 10 mm
with an polished touching surface
with zero gap (without coatings)
during detachment in a direction perpendicular to the mounting surface
at temperature approx. 20 degrees Celsius

Practical aspects of lifting capacity – factors

Bear in mind that the magnet holding will differ influenced by elements below, in order of importance:

Gap between surfaces – even a fraction of a millimeter of distance (caused e.g. by varnish or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
Direction of force – maximum parameter is obtained only during perpendicular pulling. The force required to slide of the magnet along the surface is standardly several times smaller (approx. 1/5 of the lifting capacity).
Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
Material composition – different alloys attracts identically. Alloy additives worsen the attraction effect.
Surface structure – the more even the surface, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
Temperature influence – hot environment weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity was assessed with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, however under attempts to slide the magnet the holding force is lower. Additionally, even a slight gap between the magnet’s surface and the plate reduces the load capacity.

Warnings

Warning for allergy sufferers

A percentage of the population have a sensitization to Ni, which is the standard coating for NdFeB magnets. Extended handling may cause an allergic reaction. We recommend use protective gloves.

No play value

Strictly store magnets away from children. Ingestion danger is significant, and the consequences of magnets clamping inside the body are very dangerous.

Mechanical processing

Machining of NdFeB material carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.

Caution required

Use magnets with awareness. Their huge power can surprise even professionals. Be vigilant and respect their force.

Medical interference

Individuals with a ICD should maintain an safe separation from magnets. The magnetism can stop the functioning of the life-saving device.

Do not overheat magnets

Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will ruin its magnetic structure and pulling force.

Impact on smartphones

An intense magnetic field interferes with the functioning of compasses in phones and navigation systems. Do not bring magnets near a smartphone to prevent damaging the sensors.

Crushing force

Large magnets can smash fingers in a fraction of a second. Do not put your hand betwixt two attracting surfaces.

Shattering risk

Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may crumble into hazardous fragments.

Protect data

Equipment safety: Neodymium magnets can damage data carriers and sensitive devices (heart implants, hearing aids, mechanical watches).
