Magnetic force drops sharply per each millimeter of spacing. Keep in mind that even a very thin break (e.g., dirt, varnish, dust) significantly weakens the grip. Magnetic products hold strongest during direct contact; gap nullifies the power. Observe how quickly the pull force fall, when the product does not adhere flatly to the metal substrate. When planning the mounting, discard additional spacers.

The table below defines the theoretical shear load sufficient to cause the shifting of the magnet vertically against a upright metal surface (assuming standard friction). This value depends on the distance between the magnet and the surface.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces
MPL 15x15x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	1.76 kg / 3.88 LBS 1761.0 g / 17.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.17 kg / 2.59 LBS 1174.0 g / 11.5 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.59 kg / 1.29 LBS 587.0 g / 5.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	2.94 kg / 6.47 LBS 2935.0 g / 28.8 N

When placing a magnet on a vertical plane (e.g., a board), it you can count on just about 1/5 of its maximum pull force. Gravity and a weak degree of grip mean that products move down easier than they pop off the substrate. Planning a hanger? Note that the shear force is significantly lower than the maximum static pull force. On a slippery surface, the element will give way down under a significantly smaller cargo. Using a rubber pad can effectively improve the result.

A too thin steel is not enough to take in the full magnetic flux, which wastes potential of the holder. If you mount a strong magnet to a thin surface, the magnetism will penetrate right through and the holding will be smaller. To utilize the maximum of this magnet's power, you require a sufficiently solid piece of steel. The saturation phenomenon causes that on thin elements (e.g., car bodies), the product works worse. We recommend selecting the steel cross-section according to the table below.

Classic neodymiums change their properties parameters past the thermal threshold. Protect against heat – excessive heat can irreversibly demagnetize this product. As the temperature rises, the magnet's power briefly lowers. Avoid using this product in hot environments higher than its safe range. Too high temperature will result in permanent loss of magnetism.

*Engineering note: Heat tolerance depends not only on the material grade, as well as the dimension ratios. Thin magnets (low permeance coefficient) may lose charge permanently under lower heat stress compared to rod magnets. The danger warning in the table points to permanent field degradation for this particular item.

Two magnetic products attract each other from a much further distance than a magnet and sheet setup. The setup of two magnets creates a more powerful interaction and a wider radius of operation. Designing a solid fastener? Utilize two neodymiums instead of a neodymium and a steel. Remember that when connecting a pair of magnets, the collision energy is extreme. The levitation is marginally weaker than the attraction, but still large.
*The magnetic induction between like poles reaches ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
* Calculations demonstrate friction force of two matching magnets (friction coefficient ~0.15 for Ni-Ni layer).

Table 7: Hazards (implants) - precautionary measures

A strong magnetic field is a large risk to electronic devices as well as pacemakers. These magnets produce a field that destroys function of sensitive medical devices. Be aware: the invisible magnetic field penetrates the body and glass. Special caution must be exercised by people with hearing aids and drug dispensers. The risk also applies to: mechanical watches, remotes, membranes, and screens. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

Neodymium magnets are prone to chipping – a collision with steel risks their cracking. Pay attention to connection velocity – a neodymium left loose speeds with massive force. Kinetic force can cause material chips or dangerous crushing to skin. Hold the magnet firmly during bringing near metal so it doesn't hit violently against the metal. A collision at high speed means shattering of the magnet. Wear safety glasses when playing with powerful specimens.

Warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

Water displaces steel, making heavy objects slightly lighter. However, remember the water resistance when pulling the rope quickly.

1. Wall mount (shear)

*Warning: On a vertical wall, the magnet holds just approx. 20-30% of its perpendicular strength.

2. Efficiency vs thickness

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

3. Thermal stability

*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) = 0.40

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.

Component MPL 15x15x5 / N38 features a low profile and professional pulling force, making it a perfect solution for building separators and machines. This magnetic block with a force of 57.62 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.

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 15x15x5 / 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 15x15x5 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. They work great as invisible mounts 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 15x15x5 / 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 clean and degrease 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. In practice, this means that this magnet has the greatest attraction force on its main planes (15x15 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: 15 mm (length), 15 mm (width), and 5 mm (thickness). The key parameter here is the lifting capacity amounting to approximately 5.87 kg (force ~57.62 N), which, with such a flat shape, proves the high grade of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages as well as disadvantages of Nd₂Fe₁₄B magnets.

Advantages

Besides their high retention, neodymium magnets are valued for these benefits:

They virtually do not lose power, because even after 10 years the performance loss is only ~1% (based on calculations),
Magnets effectively resist against loss of magnetization caused by foreign field sources,
The use of an shiny layer of noble metals (nickel, gold, silver) causes the element to look better,
Neodymium magnets ensure maximum magnetic induction on a small surface, which ensures high operational effectiveness,
Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
Possibility of precise machining as well as modifying to specific conditions,
Significant place in high-tech industry – they find application in HDD drives, electric motors, advanced medical instruments, as well as complex engineering applications.
Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,

Limitations

Disadvantages of neodymium magnets:

Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a special holder, 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 durability even at temperatures up to 230°C
Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
We suggest a housing - magnetic mount, due to difficulties in producing nuts inside the magnet and complicated shapes.
Potential hazard to health – tiny shards of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child health protection. Additionally, small elements of these products can be problematic in diagnostics medical when they are in the body.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Pull force analysis

Highest magnetic holding force – what affects it?

The force parameter is a result of laboratory testing conducted under the following configuration:

with the application of a yoke made of special test steel, guaranteeing full magnetic saturation
whose thickness equals approx. 10 mm
with an ground contact surface
without the slightest clearance between the magnet and steel
for force applied at a right angle (pull-off, not shear)
in stable room temperature

Key elements affecting lifting force

Real force is affected by working environment parameters, mainly (from priority):

Gap (betwixt the magnet and the plate), as even a very small distance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to paint, corrosion or debris).
Force direction – catalog parameter refers to pulling vertically. When attempting to slide, the magnet holds much less (often approx. 20-30% of nominal force).
Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of generating force.
Metal type – not every steel reacts the same. High carbon content worsen the attraction effect.
Surface condition – smooth surfaces ensure maximum contact, which improves force. Rough surfaces reduce efficiency.
Thermal factor – high temperature reduces magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.

Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the holding force.

Safe handling of NdFeB magnets

Swallowing risk

Neodymium magnets are not suitable for play. Swallowing multiple magnets can lead to them pinching intestinal walls, which poses a severe health hazard and requires urgent medical intervention.

Mechanical processing

Fire warning: Neodymium dust is explosive. Do not process magnets in home conditions as this may cause fire.

Magnetic interference

Be aware: rare earth magnets generate a field that disrupts sensitive sensors. Keep a separation from your phone, device, and navigation systems.

Heat sensitivity

Avoid heat. NdFeB magnets are susceptible to heat. If you need operation above 80°C, inquire about special high-temperature series (H, SH, UH).

Physical harm

Watch your fingers. Two large magnets will snap together instantly with a force of several hundred kilograms, crushing everything in their path. Be careful!

Electronic devices

Powerful magnetic fields can corrupt files on credit cards, hard drives, and other magnetic media. Maintain a gap of min. 10 cm.

Metal Allergy

Studies show that the nickel plating (standard magnet coating) is a strong allergen. If your skin reacts to metals, avoid touching magnets with bare hands or select versions in plastic housing.

Implant safety

For implant holders: Strong magnetic fields affect medical devices. Keep minimum 30 cm distance or request help to handle the magnets.

Magnets are brittle

Despite the nickel coating, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.

Respect the power

Be careful. Neodymium magnets act from a long distance and snap with massive power, often quicker than you can react.
