Grip strength drops sharply with every mm of distance. Keep in mind that even a microscopic distance (e.g., contamination, varnish, veneer) noticeably reduces the pull force. Magnetic products operate optimally during direct contact; gap nullifies the force. Notice how flashily the load capacity plummet, when the product does not adhere tightly to the metal substrate. When designing the assembly, eliminate additional spacers.

The following data presents the approximate holding capacity needed to cause the slippage of the magnet down on a vertical steel plate (assuming typical friction coefficient). This parameter varies with the air gap between the magnet and the metal.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	5.02 kg / 11.06 lbs 5016.0 g / 49.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	3.34 kg / 7.37 lbs 3344.0 g / 32.8 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	1.67 kg / 3.69 lbs 1672.0 g / 16.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	8.36 kg / 18.43 lbs 8360.0 g / 82.0 N

When placing a holder on a vertical surface (e.g., a board), it will only hold barely approx. 20%-30% of its maximum pull force. Gravity as well as a low friction coefficient cause that holders move down easier than they pop off the substrate. Planning a vertical fastening? Remember that the sliding force is much weaker than the maximum static pull force. On a slippery surface, the element will give way down under a much lighter cargo. Utilizing a rubberized layer can drastically improve the result.

A thin metal plate is incapable of absorb the entire magnetic field, which weakens actual performance of the magnet. Should you attach a powerful product to a thin surface, the field will pass right through and the attraction force will be weaker. To achieve full efficiency of this neodymium's power, you require a sufficiently solid element of steel. The saturation effect causes that on sheet metal structures (e.g., appliance housings), the holder holds weaker. We suggest choosing the steel cross-section according to the table below.

Standard neodymium magnets change their properties strength above the temperature limit. Avoid high temperatures – excessive heat can irreversibly destroy this product. With increasing heat, the neodymium's force briefly decreases. Refrain from using this magnet close to ovens higher than its safe range. Ignoring the limit will lead to destruction of magnetism.

*Important note: Thermal stability is determined by both grade, as well as the dimension ratios. Flat magnets (low permeance coefficient) risk losing magnetic properties sooner than long magnets. Red status in the table points to a risk of irreversible loss for this specific geometry.

Two strong neodymiums attract each other from a significantly greater distance than a neodymium and metal setup. The connection of magnet-to-magnet creates a more powerful interaction and a wider radius of action. Designing a strong closure? Utilize two neodymiums instead of a neodymium and a steel. Be careful that when bringing together two magnets, the collision energy is huge. The levitation is marginally weaker than the attraction, but still significant.
*Field value between like poles reaches ~0 Gs at the geometric center of the gap (resulting from vector opposition).
Note: Estimates demonstrate shear force of a pair of identical magnets (friction coefficient ~0.15 for Ni-Ni plating).

Powerful magnet radiation poses a large risk to electronics and pacemakers. These NdFeB products generate a flux that prevents correct functioning of digital equipment. Be aware: the unseen radiation passes through tissues and plastic. Special caution must be taken by people with cochlear implants and drug dispensers. Influence will be felt by: automatic timepieces, remotes, membranes, and displays. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Neodymium magnets are prone to chipping – a collision with steel can result in shattering. Pay attention to connection velocity – a magnet released freely speeds with massive force. Impact energy can destroy the magnet or dangerous crushing to skin. Always hold the magnet during mounting so it doesn't slam with momentum against the metal. A collision at high speed almost guarantees destruction of the neodymium. Wear eye protection when playing with powerful specimens.

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

1. Wall mount (shear)

*Note: On a vertical surface, the magnet retains only ~20% of its max power.

2. Steel thickness impact

*Thin metal sheet (e.g. computer case) drastically weakens the holding force.

3. Thermal stability

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.79

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.

This product is a very powerful magnet in the shape of a plate made of NdFeB material, which, with dimensions of 40x10x18 mm and a weight of 54 g, guarantees the highest quality connection. This magnetic block with a force of 164.01 N is ready for shipment in 24h, allowing for rapid realization of your project. Additionally, its Ni-Cu-Ni coating protects it against corrosion in standard operating conditions, giving it an aesthetic appearance.

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 40x10x18 / 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.

Plate magnets MPL 40x10x18 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. Thanks to the flat surface and high force (approx. 16.72 kg), they are ideal as closers in furniture making and mounting elements in automation. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.

Cyanoacrylate glues (super glue type) are good only for small magnets; for larger plates, we recommend resins. Double-sided tape cushions vibrations, which is an advantage when mounting in moving elements. Avoid chemically aggressive glues or hot glue, which can demagnetize neodymium (above 80°C).

Standardly, the MPL 40x10x18 / N38 model is magnetized through the thickness (dimension 18 mm), which means that the N and S poles are located on its largest, flat surfaces. In practice, this means that this magnet has the greatest attraction force on its main planes (40x10 mm), which is ideal for flat mounting. Such a pole arrangement ensures maximum holding capacity when pressing against the sheet, creating a closed magnetic circuit.

The presented product is a neodymium magnet with precisely defined parameters: 40 mm (length), 10 mm (width), and 18 mm (thickness). The key parameter here is the holding force amounting to approximately 16.72 kg (force ~164.01 N), which, with such a compact shape, proves the high power of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Strengths and weaknesses of neodymium magnets.

Benefits

Besides their remarkable pulling force, neodymium magnets offer the following advantages:

They retain magnetic properties for nearly 10 years – the loss is just ~1% (based on simulations),
Magnets very well protect themselves against demagnetization caused by external fields,
Thanks to the elegant finish, the plating of nickel, gold-plated, or silver gives an visually attractive appearance,
They show 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 work (depending on the form) even at a temperature of 230°C or more...
Possibility of accurate creating as well as adjusting to specific conditions,
Significant place in modern technologies – they find application in mass storage devices, motor assemblies, medical equipment, and industrial machines.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Weaknesses

Drawbacks and weaknesses of neodymium magnets: application proposals

Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a steel housing, which not only protects them against impacts but also raises their durability
Neodymium magnets lose 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 durability even at temperatures up to 230°C
Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
Due to limitations in creating nuts and complicated shapes in magnets, we propose using cover - magnetic holder.
Possible danger to health – tiny shards of magnets pose a threat, when accidentally swallowed, which becomes key in the context of child health protection. Furthermore, tiny parts of these products are able to disrupt the diagnostic process medical after entering the body.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Lifting parameters

Maximum magnetic pulling force – what it depends on?

Breakaway force was defined for the most favorable conditions, taking into account:

with the application of a yoke made of special test steel, ensuring maximum field concentration
whose thickness reaches at least 10 mm
with an ground contact surface
with direct contact (no impurities)
during detachment in a direction perpendicular to the plane
at ambient temperature room level

Practical aspects of lifting capacity – factors

It is worth knowing that the working load will differ subject to the following factors, in order of importance:

Gap (betwixt the magnet and the metal), because even a very small clearance (e.g. 0.5 mm) can cause a reduction in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
Angle of force application – maximum parameter is available only during pulling at a 90° angle. The force required to slide of the magnet along the plate is standardly several times smaller (approx. 1/5 of the lifting capacity).
Base massiveness – insufficiently thick plate causes magnetic saturation, causing part of the power to be escaped to the other side.
Material type – the best choice is pure iron steel. Cast iron may generate lower lifting capacity.
Plate texture – smooth surfaces guarantee perfect abutment, which increases field saturation. Rough surfaces 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 was measured by applying a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under shearing force the holding force is lower. In addition, even a small distance between the magnet and the plate decreases the lifting capacity.

Precautions when working with neodymium magnets

Sensitization to coating

Medical facts indicate that the nickel plating (standard magnet coating) is a strong allergen. If you have an allergy, refrain from direct skin contact and select versions in plastic housing.

Crushing force

Danger of trauma: The pulling power is so immense that it can result in blood blisters, crushing, and even bone fractures. Protective gloves are recommended.

Machining danger

Dust created during cutting of magnets is flammable. Do not drill into magnets unless you are an expert.

Phone sensors

A powerful magnetic field negatively affects the operation of compasses in smartphones and GPS navigation. Maintain magnets close to a device to prevent breaking the sensors.

Fragile material

Despite metallic appearance, the material is delicate and not impact-resistant. Do not hit, as the magnet may crumble into sharp, dangerous pieces.

Life threat

Life threat: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.

Keep away from children

These products are not toys. Accidental ingestion of multiple magnets can lead to them pinching intestinal walls, which poses a severe health hazard and requires immediate surgery.

Keep away from computers

Do not bring magnets near a wallet, laptop, or TV. The magnetic field can destroy these devices and erase data from cards.

Respect the power

Handle with care. Rare earth magnets act from a long distance and snap with massive power, often faster than you can react.

Power loss in heat

Control the heat. Heating the magnet to high heat will permanently weaken its magnetic structure and pulling force.

Caution! Learn more about hazards in the article: Magnet Safety Guide.
