Magnetic force decreases sharply with every subsequent millimeter of gap. Remember that even a very thin break (e.g., dirt, varnish, dust) noticeably reduces the pull force. Neodymiums hold optimally during direct contact; gap nullifies the power. See how rapidly the parameters plummet, when the magnet does not adhere flatly to the metal substrate. When calculating the mounting, eliminate redundant distances.

The following data presents the theoretical force sufficient to initiate the shifting of the magnet vertically along a upright metal surface (assuming standard friction coefficient). This parameter varies with the gap size between the magnet and the metal.

Table 3: Wall mounting (shearing) - behavior on slippery surfaces
MPL 50x30x4 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	2.27 kg / 5.01 LBS 2271.0 g / 22.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.51 kg / 3.34 LBS 1514.0 g / 14.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.76 kg / 1.67 LBS 757.0 g / 7.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	3.79 kg / 8.34 LBS 3785.0 g / 37.1 N

When mounting a element on a vertical plane (e.g., a fridge), it you can count on barely about 20%-30% of its nominal power. Gravity and a weak degree of grip influence the fact that magnets move down easier than they pull off. Planning a wall mount? Note that the shear force is significantly lower than the perpendicular breakaway force. On a painted metal, the element will slip down under a significantly smaller load. Using a rubber layer can drastically improve the result.

A too thin steel is not enough to absorb the entire magnetic field, which squanders power of the magnet. If you attach a powerful product to a weak sheet, the magnetism will penetrate 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 saturation phenomenon means that on thin elements (e.g., thin profiles), the holder shows lower pull force. We advise picking the steel dimension from these parameters.

Ordinary NdFeB products lose power above the temperature limit. Avoid high temperatures – high temperature can permanently demagnetize this magnet. As the temperature rises, the magnet's capacity briefly lowers. Refrain from using this product close to ovens higher than its working range. Ignoring the limit will cause irreversible degradation of magnetic properties.

*Important note: Thermal stability is determined by both grade, and the Permeance Coefficient Pc. Thin magnets (pancake types) are more susceptible to demagnetization sooner compared to rod magnets. Red status in the table indicates a risk of irreversible loss for this particular item.

Two magnetic products interact from a wider radius than a magnet and sheet setup. Such a system of two magnets generates a stronger field and a further horizon of performance. Designing a strong closure? Apply two magnets instead of a neodymium and a striker plate. Exercise caution that when bringing together two magnets, the pinch force is extreme. The levitation is slightly lower than the attraction, but still significant.
*Flux density for N-N configuration reaches ~0 Gs at the midpoint of the gap (caused by magnetic field nullification).
Attention: Figures show friction force of a pair of matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

Powerful magnet radiation is a real danger to IT equipment and medical implants. These magnets produce a flux that destroys function of digital equipment. Remember: the invisible magnetic field passes through tissues and glass. Special caution must be taken by people with hearing aids and drug dispensers. Also at risk are: automatic timepieces, car keys, membranes, and screens. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Magnetic elements are delicate – a violent impact against metal can result in shattering. Watch the impact speed – a magnet released freely becomes dangerous. Kinetic force can destroy the magnet or dangerous crushing to skin. Be sure to control the product during mounting so it doesn't hit with great force against the metal. A collision at high speed almost guarantees destruction of the neodymium. Wear safety glasses when handling 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!

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

1. Shear force

*Caution: On a vertical wall, the magnet retains just a fraction of its max power.

2. Plate thickness effect

*Thin metal sheet (e.g. computer case) significantly limits the holding force.

3. Thermal stability

*For standard magnets, the safety limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.14

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.

Model MPL 50x30x4 / N38 features a flat shape and industrial pulling force, making it a perfect solution for building separators and machines. As a magnetic bar with high power (approx. 7.57 kg), this product is available off-the-shelf from our warehouse in Poland. The durable anti-corrosion layer ensures a long lifespan in a dry environment, protecting the core from oxidation.

Separating strong flat magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. To separate the MPL 50x30x4 / N38 model, firmly slide one magnet over the edge of the other until the attraction force decreases. We recommend extreme caution, because after separation, the magnets may want to violently snap back together, which threatens pinching the skin. Never use metal tools for prying, as the brittle NdFeB material may chip and damage your eyes.

They constitute a key element in the production of wind generators and material handling systems. They work great as fasteners under tiles, wood, or glass. Customers often choose this model for hanging tools on strips and for advanced DIY and modeling projects, where precision and power count.

For mounting flat magnets MPL 50x30x4 / N38, we recommend utilizing strong epoxy glues (e.g., UHU Endfest, Distal), which ensure a durable bond with metal or plastic. For lighter applications or mounting on smooth surfaces, branded foam tape (e.g., 3M VHB) will work, provided the surface is perfectly degreased. Avoid chemically aggressive glues or hot glue, which can demagnetize neodymium (above 80°C).

Standardly, the MPL 50x30x4 / N38 model is magnetized through the thickness (dimension 4 mm), which means that the N and S poles are located on its largest, flat surfaces. Thanks to this, it works best when "sticking" to sheet metal or another magnet with a large surface area. This is the most popular configuration for block magnets used in separators and holders.

This model is characterized by dimensions 50x30x4 mm, which, at a weight of 45 g, makes it an element with high energy density. It is a magnetic block with dimensions 50x30x4 mm and a self-weight of 45 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Advantages and disadvantages of rare earth magnets.

Advantages

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

They retain magnetic properties for almost ten years – the loss is just ~1% (in theory),
They have excellent resistance to magnetism drop as a result of opposing magnetic fields,
In other words, due to the metallic layer of silver, the element becomes visually attractive,
They are known for high magnetic induction at the operating surface, which affects their effectiveness,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
Possibility of detailed forming as well as adapting to concrete applications,
Versatile presence in advanced technology sectors – they find application in hard drives, motor assemblies, diagnostic systems, as well as technologically advanced constructions.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Cons

Disadvantages of NdFeB magnets:

Brittleness is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a steel housing, which not only secures them against impacts but also raises their durability
Neodymium magnets decrease their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
Due to limitations in producing threads and complicated forms in magnets, we propose using cover - magnetic mount.
Possible danger resulting from small fragments of magnets pose a threat, in case of ingestion, which gains importance in the aspect of protecting the youngest. Furthermore, tiny parts of these products can complicate diagnosis medical when they are in the body.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities

Lifting parameters

Detachment force of the magnet in optimal conditions – what contributes to it?

The lifting capacity listed is a measurement result executed under standard conditions:

with the use of a yoke made of special test steel, guaranteeing maximum field concentration
with a thickness of at least 10 mm
with a surface cleaned and smooth
with total lack of distance (no impurities)
during pulling in a direction vertical to the plane
at room temperature

Determinants of practical lifting force of a magnet

Bear in mind that the application force may be lower depending on the following factors, starting with the most relevant:

Air gap (between the magnet and the metal), since even a tiny distance (e.g. 0.5 mm) results in a drastic drop in force by up to 50% (this also applies to varnish, corrosion or debris).
Direction of force – highest force is reached only during pulling at a 90° angle. The shear force of the magnet along the surface is usually several times smaller (approx. 1/5 of the lifting capacity).
Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
Chemical composition of the base – mild steel gives the best results. Alloy steels reduce magnetic permeability and lifting capacity.
Surface quality – the smoother and more polished the plate, the better the adhesion and stronger the hold. Roughness creates an air distance.
Thermal environment – heating the magnet causes a temporary drop of force. Check the thermal limit for a given model.

Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, 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 reduces the holding force.

Warnings

Skin irritation risks

Studies show that the nickel plating (standard magnet coating) is a strong allergen. If you have an allergy, avoid direct skin contact or select encased magnets.

Finger safety

Risk of injury: The pulling power is so immense that it can cause hematomas, crushing, and broken bones. Use thick gloves.

GPS Danger

Note: rare earth magnets produce a field that disrupts sensitive sensors. Maintain a separation from your phone, tablet, and GPS.

Beware of splinters

Watch out for shards. Magnets can explode upon uncontrolled impact, ejecting shards into the air. Wear goggles.

Do not drill into magnets

Combustion risk: Rare earth powder is highly flammable. Do not process magnets in home conditions as this risks ignition.

Adults only

These products are not intended for children. Eating a few magnets can lead to them pinching intestinal walls, which poses a severe health hazard and requires immediate surgery.

Electronic hazard

Do not bring magnets close to a wallet, computer, or screen. The magnetism can destroy these devices and wipe information from cards.

Heat sensitivity

Watch the temperature. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and strength.

Handling rules

Use magnets consciously. Their immense force can shock even experienced users. Plan your moves and do not underestimate their power.

Warning for heart patients

Warning for patients: Strong magnetic fields affect electronics. Keep minimum 30 cm distance or ask another person to work with the magnets.
