Pulling power drops sharply with every mm of gap. Remember that even a very thin break (e.g., contamination, varnish, rust) significantly diminishes the holding power. Neodymiums work strongest at the point of direct contact; air break drastically cuts the power. Notice how quickly the pull force fall, when the magnet does not adhere flatly to the metal substrate. When calculating the mounting, avoid additional spacers.

The table below presents the estimated weight limit necessary to start the downward movement of the magnet vertically against a vertical steel plate (assuming standard friction coefficient). This value is a function of the air gap between the magnet and the surface.

Table 3: Wall mounting (shearing) - vertical pull
MPL 40x15x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	3.41 kg / 7.51 pounds 3405.0 g / 33.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	2.27 kg / 5.00 pounds 2270.0 g / 22.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	1.14 kg / 2.50 pounds 1135.0 g / 11.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	5.68 kg / 12.51 pounds 5675.0 g / 55.7 N

When mounting a element on a vertical plane (e.g., a fridge), it will maintain only about 20%-30% of its maximum pull force. Gravitational force as well as a low friction coefficient cause that products slide down faster than they pop off the substrate. Planning a wall mount? Consider that the shear force is noticeably lower than the perpendicular breakaway force. On a smooth steel, the magnet will slide down under a significantly smaller load. Application of an anti-slip coating can significantly improve the result.

A thin metal plate is not enough to focus the entire magnetic field, which weakens actual performance of the holder. Should you install a neodymium to a thin surface, the field will pass right through and the pull force will drop sharply. To squeeze 100% of this magnet's potential, you need a suitably thick piece of steel. The saturation phenomenon means that on delicate walls (e.g., thin profiles), the holder holds weaker. We recommend selecting the steel thickness from these parameters.

Standard neodymium magnets change their properties parameters past the thermal threshold. Watch out for overheating – heat can irreversibly damage this magnet. As the temperature rises, the neodymium's power temporarily decreases. Avoid using this magnet in hot environments exceeding its operating temperature limit. Exceeding the critical threshold will cause irreversible degradation of magnetism.

*Engineering note: Temperature resistance is determined by both grade, but also on the magnet's shape. Low-profile magnets (low permeance coefficient) risk losing magnetic properties sooner than taller cylinders. Warning indicator in the table signals permanent field degradation for this particular item.

Two magnetic products attract each other from a much further distance than a neodymium and metal setup. The connection of magnet-to-magnet produces a massive flux and a larger range of performance. Designing a strong closure? Apply two magnets instead of a neodymium and a striker plate. Remember that when bringing together two magnets, the impact force is extreme. The repulsion force is marginally weaker than the attraction, but still large.
*Flux density between like poles drops to ~0 Gs at the geometric center of the gap (caused by magnetic field nullification).
Important: Estimates show friction force of dual identical neodymium magnets (friction ~0.15 for Ni-Ni plating).

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

A strong magnetic field is a serious hazard to electronic devices as well as pacemakers. These neodymiums produce a flux that disrupts operation of sensitive medical devices. Remember: the invisible magnetic field acts through matter and housings. Special caution must be exercised by people with hearing aids and drug dispensers. Influence will be felt by: automatic timepieces, remotes, membranes, and displays. Do not bring the product near payment cards, hard drives, or sensitive navigation tools.

NdFeB products are very brittle – a strong collision with metal causes immediate chipping. Pay attention to connection velocity – a magnet released freely becomes dangerous. Striking energy can destroy the magnet or dangerous crushing to skin. Be sure to control the product during installation so it doesn't hit with great force against the metal. A collision at high speed means shattering of the magnet. Use safety goggles 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!

The magnetic field penetrates through water without any losses. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Shear force

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

2. Steel saturation

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

3. Power loss vs temp

*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) = 0.26

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.

Component MPL 40x15x5 / N38 features a low profile and industrial pulling force, making it an ideal solution for building separators and machines. As a block magnet with high power (approx. 11.35 kg), this product is available off-the-shelf from our warehouse in Poland. Additionally, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, giving it an aesthetic appearance.

The key to success is sliding 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 40x15x5 / 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. Thanks to the flat surface and high force (approx. 11.35 kg), they are ideal as closers in furniture making and mounting elements in automation. Customers often choose this model for hanging tools on strips and for advanced DIY and modeling projects, where precision and power count.

Cyanoacrylate glues (super glue type) are good only for small magnets; for larger plates, we recommend resins. For lighter applications or mounting on smooth surfaces, branded foam tape (e.g., 3M VHB) will work, provided the surface is perfectly degreased. Remember to clean and degrease the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

Standardly, the MPL 40x15x5 / N38 model is magnetized axially (dimension 5 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 (40x15 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.

This model is characterized by dimensions 40x15x5 mm, which, at a weight of 22.5 g, makes it an element with high energy density. The key parameter here is the lifting capacity amounting to approximately 11.35 kg (force ~111.37 N), which, with such a compact shape, proves the high grade of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Strengths and weaknesses of neodymium magnets.

Strengths

In addition to their magnetic capacity, neodymium magnets provide the following advantages:

They do not lose magnetism, even over approximately ten years – the decrease in lifting capacity is only ~1% (according to tests),
They show high resistance to demagnetization induced by external disturbances,
Thanks to the shimmering finish, the layer of nickel, gold-plated, or silver-plated gives an professional appearance,
Magnetic induction on the working part of the magnet turns out to be extremely intense,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
Thanks to freedom in constructing and the ability to adapt to unusual requirements,
Versatile presence in electronics industry – they are used in hard drives, drive modules, medical equipment, as well as modern systems.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Cons

Disadvantages of NdFeB magnets:

To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
NdFeB magnets lose force 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 extremely resistant to heat
They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
Due to limitations in creating threads and complicated shapes in magnets, we recommend using a housing - magnetic mechanism.
Potential hazard related to microscopic parts of magnets pose a threat, when accidentally swallowed, which becomes key in the context of child safety. It is also worth noting that small elements of these devices can be problematic in diagnostics medical after entering the body.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Lifting parameters

Maximum lifting force for a neodymium magnet – what affects it?

The specified lifting capacity represents the maximum value, recorded under ideal test conditions, namely:

with the application of a yoke made of low-carbon steel, ensuring full magnetic saturation
possessing a massiveness of min. 10 mm to avoid saturation
characterized by lack of roughness
with direct contact (no coatings)
during detachment in a direction vertical to the mounting surface
in stable room temperature

Determinants of lifting force in real conditions

It is worth knowing that the application force will differ subject to the following factors, starting with the most relevant:

Clearance – the presence of foreign body (rust, tape, air) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the nominal value.
Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
Chemical composition of the base – mild steel attracts best. Higher carbon content lower magnetic properties and lifting capacity.
Surface structure – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
Operating temperature – neodymium magnets have a sensitivity to temperature. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).

Lifting capacity was determined using a steel plate with a smooth surface of suitable thickness (min. 20 mm), under vertically applied force, whereas under shearing force the load capacity is reduced by as much as 5 times. Additionally, even a small distance between the magnet and the plate lowers the holding force.

Safety rules for work with neodymium magnets

Threat to navigation

GPS units and mobile phones are extremely sensitive to magnetism. Close proximity with a powerful NdFeB magnet can permanently damage the sensors in your phone.

Bodily injuries

Danger of trauma: The pulling power is so immense that it can cause blood blisters, pinching, and broken bones. Use thick gloves.

Do not give to children

Product intended for adults. Small elements can be swallowed, causing intestinal necrosis. Keep out of reach of children and animals.

Respect the power

Exercise caution. Neodymium magnets act from a long distance and snap with massive power, often faster than you can react.

Maximum temperature

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

Health Danger

For implant holders: Strong magnetic fields affect medical devices. Maintain minimum 30 cm distance or ask another person to work with the magnets.

Warning for allergy sufferers

Medical facts indicate that nickel (the usual finish) is a strong allergen. For allergy sufferers, refrain from touching magnets with bare hands or opt for coated magnets.

Beware of splinters

NdFeB magnets are sintered ceramics, meaning they are very brittle. Impact of two magnets will cause them breaking into shards.

Safe distance

Do not bring magnets near a wallet, laptop, or screen. The magnetic field can irreversibly ruin these devices and wipe information from cards.

Machining danger

Powder generated during grinding of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.

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