Magnetic force decreases significantly with every subsequent millimeter of distance. Keep in mind that even the smallest gap (e.g., contamination, paint, dust) significantly weakens the grip. Neodymiums hold optimally during direct contact; gap weakens the power. See how flashily the parameters fall, when the magnet does not touch tightly to the steel surface. When planning the arrangement, discard unnecessary gaps.

This section indicates the theoretical weight limit necessary to cause the downward movement of the magnet down along a upright metal surface (assuming typical friction coefficient). This parameter varies with the separation distance between the magnet and the surface.

Table 3: Wall mounting (sliding) - vertical pull
MPL 40x40x15 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	14.08 kg / 31.05 pounds 14082.0 g / 138.1 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	9.39 kg / 20.70 pounds 9388.0 g / 92.1 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	4.69 kg / 10.35 pounds 4694.0 g / 46.0 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	23.47 kg / 51.74 pounds 23470.0 g / 230.2 N

When placing a element on a upright wall (e.g., a car body), it will only hold barely approx. 1/5 of nominal attraction strength. Gravitational force as well as a low friction coefficient mean that holders move down faster than they pull off. Want to create a hanger? Note that the shear force is much weaker than the maximum static pull force. On a smooth steel, the magnet will slide down under a much lighter weight. Application of an anti-slip pad can significantly increase the grip.

A thin metal plate is not enough to focus the entire magnetic field, which wastes potential of the magnet. If you attach a powerful product to a too thin substrate, the field will penetrate right through and the attraction force will be weaker. To achieve 100% of this magnet's power, you require a sufficiently solid piece of steel. The material oversaturation means that on thin elements (e.g., thin profiles), the holder works worse. We advise picking the steel cross-section according to the table below.

Standard neodymium magnets change their properties power above the temperature limit. Protect against heat – heat can irreversibly demagnetize this product. With every degree above norm, the magnet's power momentarily decreases. Refrain from using this magnet near heat sources exceeding its operating temperature limit. Ignoring the limit will lead to irreversible degradation of magnetic properties.

*Engineering note: Heat tolerance depends not only on the material grade, as well as the dimension ratios. Low-profile magnets (pancake types) may lose charge permanently at lower temperatures than taller cylinders. The danger warning in the table indicates a risk of irreversible loss for this specific geometry.

Two magnets interact from a significantly greater distance than a magnet and steel combination. The setup of two magnets produces a massive flux and a larger range of action. Designing a solid fastener? Use a pair of magnets instead of one magnet and a striker plate. Exercise caution that when attracting two neodymiums, the pinch 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 in the exact middle between the magnets (resulting from vector opposition).
Note: Estimates apply to sliding force of a pair of same magnets (friction ~0.15 for Ni-Ni layer).

Table 7: Safety (HSE) (electronics) - warnings
MPL 40x40x15 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	20.5 cm

A strong magnetic field is a large risk to IT equipment and pacemakers. These magnets generate a field that disrupts operation of digital equipment. Remember: the unseen radiation acts through matter and glass. Special caution must be taken by people with hearing aids and insulin pumps. Also at risk are: mechanical watches, car keys, membranes, and screens. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

Table 8: Impact energy (cracking risk) - collision effects
MPL 40x40x15 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	19.62 km/h (5.45 m/s)	2.67 J
30 mm	28.70 km/h (7.97 m/s)	5.72 J
50 mm	36.50 km/h (10.14 m/s)	9.25 J
100 mm	51.50 km/h (14.31 m/s)	18.42 J

Magnetic elements are delicate – a strong collision with metal risks their cracking. Control the attraction moment – a magnet released freely turns into a projectile. Kinetic force can destroy the magnet or dangerous crushing to skin. Always hold the magnet during bringing near metal so it doesn't slam with momentum against the metal. A collision at high speed means shattering of the magnet. Wear eye protection when working with powerful specimens.

Environment	Effective steel pull	Effect
Air (land)	46.94 kg	Standard
Water (riverbed)	53.75 kg (+6.81 kg buoyancy gain)	+14.5%

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

The magnetic field penetrates through water without any losses. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Shear force

*Note: On a vertical wall, the magnet retains only approx. 20-30% of its perpendicular strength.

2. Efficiency vs thickness

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

3. Heat tolerance

*For standard magnets, 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) = 0.43

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.

This product is an extremely strong magnet in the shape of a plate made of NdFeB material, which, with dimensions of 40x40x15 mm and a weight of 180 g, guarantees premium class connection. This magnetic block with a force of 460.51 N is ready for shipment in 24h, allowing for rapid realization of your project. The durable anti-corrosion layer ensures a long lifespan in a dry environment, protecting the core from oxidation.

Separating block magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. To separate the MPL 40x40x15 / 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. Never use metal tools for prying, as the brittle NdFeB material may chip and damage your eyes.

Plate magnets MPL 40x40x15 / N38 are the foundation for many industrial devices, such as filters catching filings and linear motors. Thanks to the flat surface and high force (approx. 46.94 kg), they are ideal as closers in furniture making and mounting elements in automation. Customers often choose this model for workshop organization on strips and for advanced DIY and modeling projects, where precision and power count.

For mounting flat magnets MPL 40x40x15 / N38, it is best to use two-component adhesives (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 40x40x15 / N38 model is magnetized axially (dimension 15 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 (40x40 mm), which is ideal for flat mounting. This is the most popular configuration for block magnets used in separators and holders.

This model is characterized by dimensions 40x40x15 mm, which, at a weight of 180 g, makes it an element with high energy density. The key parameter here is the holding force amounting to approximately 46.94 kg (force ~460.51 N), which, with such a compact shape, proves the high grade of the material. The product meets the standards for N38 grade magnets.

Strengths and weaknesses of neodymium magnets.

Pros

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

Their strength is maintained, and after around ten years it decreases only by ~1% (theoretically),
Neodymium magnets are distinguished by exceptionally resistant to magnetic field loss caused by external field sources,
The use of an shiny coating of noble metals (nickel, gold, silver) causes the element to have aesthetics,
The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing 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...
Thanks to the potential of precise shaping and customization to individualized projects, neodymium magnets can be modeled in a broad palette of geometric configurations, which increases their versatility,
Wide application in advanced technology sectors – they find application in data components, electric motors, medical equipment, also multitasking production systems.
Thanks to concentrated force, small magnets offer high operating force, in miniature format,

Cons

Disadvantages of neodymium magnets:

To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
Limited ability of making threads in the magnet and complex forms - recommended is a housing - mounting mechanism.
Possible danger related to microscopic parts of magnets can be dangerous, if swallowed, which is particularly important in the context of child health protection. It is also worth noting that tiny parts of these devices can disrupt the diagnostic process medical after entering the body.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Pull force analysis

Maximum lifting capacity of the magnet – what it depends on?

The force parameter is a theoretical maximum value performed under the following configuration:

with the application of a sheet made of special test steel, ensuring maximum field concentration
whose transverse dimension is min. 10 mm
with a plane perfectly flat
under conditions of no distance (surface-to-surface)
for force applied at a right angle (in the magnet axis)
at temperature approx. 20 degrees Celsius

Lifting capacity in real conditions – factors

Holding efficiency is affected by specific conditions, such as (from priority):

Clearance – existence of any layer (paint, tape, gap) acts as an insulator, which reduces capacity rapidly (even by 50% at 0.5 mm).
Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
Steel type – mild steel attracts best. Alloy admixtures reduce magnetic properties and lifting capacity.
Smoothness – full contact is possible only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
Operating temperature – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and in frost gain strength (up to a certain limit).

Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate lowers the lifting capacity.

Warnings

Magnets are brittle

Neodymium magnets are sintered ceramics, meaning they are fragile like glass. Clashing of two magnets leads to them cracking into shards.

Hand protection

Risk of injury: The attraction force is so great that it can result in hematomas, crushing, and broken bones. Use thick gloves.

Demagnetization risk

Control the heat. Exposing the magnet above 80 degrees Celsius will permanently weaken its properties and pulling force.

Mechanical processing

Fire warning: Rare earth powder is highly flammable. Do not process magnets in home conditions as this may cause fire.

Impact on smartphones

A powerful magnetic field disrupts the functioning of compasses in phones and navigation systems. Maintain magnets close to a device to avoid damaging the sensors.

Immense force

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

Warning for allergy sufferers

A percentage of the population experience a hypersensitivity to nickel, which is the standard coating for neodymium magnets. Extended handling can result in dermatitis. We strongly advise use protective gloves.

Pacemakers

Health Alert: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.

Adults only

Strictly store magnets out of reach of children. Risk of swallowing is significant, and the effects of magnets clamping inside the body are very dangerous.

Threat to electronics

Very strong magnetic fields can erase data on payment cards, HDDs, and other magnetic media. Maintain a gap of min. 10 cm.
