Magnetic force drops sharply with every mm of spacing. Note that even a microscopic distance (e.g., contamination, paint, veneer) significantly reduces the pull force. Magnetic products work most effectively at the point of direct contact; distance kills the force. Notice how rapidly the pull force plummet, when the magnet does not touch directly to the metal substrate. When calculating the assembly, avoid unnecessary gaps.

The following data indicates the approximate weight limit needed to initiate the shifting of the magnet down along a vertical steel wall (considering typical friction coefficient). This parameter is a function of the separation distance between the magnet and the surface.

Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.38 kg / 0.83 LBS 376.0 g / 3.7 N

When mounting a element on a upright plane (e.g., a car body), it will maintain barely approx. 1/5 of its nominal power. Gravity as well as a weak degree of grip influence the fact that products slip faster than they detach. Designing a hanger? Remember that the sliding force is much weaker than the perpendicular breakaway force. On a smooth steel, the element will give way down under a significantly smaller load. Utilizing a rubberized coating can effectively improve the result.

A thin metal plate cannot absorb the entire magnetic field, which wastes potential of the magnet. If you mount a strong magnet to a thin surface, the flux will penetrate right through and the holding will be smaller. To achieve 100% of this magnet's potential, you require a sufficiently solid backing of steel. The saturation effect causes that on thin elements (e.g., appliance housings), the product holds weaker. We advise picking the steel thickness according to the table below.

Ordinary NdFeB products change their properties power past the thermal threshold. Watch out for overheating – excessive heat can irreversibly destroy this magnet. With increasing heat, the neodymium's capacity momentarily drops. Avoid using this product in hot environments exceeding its working range. Too high temperature will lead to destruction of magnetism.

*Technical advisory: Heat tolerance depends not only on the material grade, and the Permeance Coefficient Pc. Low-profile magnets (low permeance coefficient) may lose charge permanently sooner than long 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 neodymium and metal setup. Such a system of two magnets produces a massive flux and a larger range of performance. Want to build a powerful holder? Apply two magnets instead of one magnet and a striker plate. Be careful that when attracting two neodymiums, the pinch force is extreme. The repulsion force is a bit weaker than the attraction, but still significant.
*Field value between like poles is approximately ~0 Gs at the geometric center between the magnets (due to field cancellation).
* Results demonstrate shear force of a pair of matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni plating).

Extremely neodym field poses a real danger to IT equipment and pacemakers. These NdFeB products produce a flux that disrupts operation of digital equipment. Be aware: the invisible magnetic field acts through matter and glass. Exceptional care must be exercised by people with cochlear implants and drug dispensers. Also at risk are: mechanical watches, remotes, membranes, and displays. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Table 8: Dynamics (kinetic energy) - collision effects

Start from (mm)	Speed (km/h)	Energy (J)

NdFeB products are very brittle – a violent impact against metal can result in shattering. Pay attention to connection velocity – a neodymium left loose speeds with massive force. Impact energy can trigger coating fragments or dangerous crushing to skin. Hold the magnet firmly during mounting so it doesn't hit with great force against the steel surface. A contact at a velocity of dozens of km/h almost guarantees destruction of the neodymium. Wear safety glasses when working with powerful specimens.

Corrosion warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

Water displaces steel, making heavy objects slightly lighter. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Wall mount (shear)

*Warning: On a vertical wall, the magnet retains just a fraction of its nominal pull.

2. Efficiency vs thickness

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

3. Thermal stability

*For N38 grade, the critical limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.19

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 plate magnet made of NdFeB material, which, with dimensions of 20x10x2 mm and a weight of 3 g, guarantees premium class connection. This magnetic block with a force of 18.44 N is ready for shipment in 24h, allowing for rapid realization of your project. Furthermore, its Ni-Cu-Ni coating protects it against corrosion in standard operating conditions, giving it an aesthetic appearance.

The key to success is shifting 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 20x10x2 / 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 20x10x2 / 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. 1.88 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. Avoid chemically aggressive glues or hot glue, which can demagnetize neodymium (above 80°C).

Standardly, the MPL 20x10x2 / N38 model is magnetized through the thickness (dimension 2 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.

The presented product is a neodymium magnet with precisely defined parameters: 20 mm (length), 10 mm (width), and 2 mm (thickness). The key parameter here is the holding force amounting to approximately 1.88 kg (force ~18.44 N), which, with such a compact shape, proves the high grade of the material. The product meets the standards for N38 grade magnets.

Strengths as well as weaknesses of rare earth magnets.

Strengths

Besides their tremendous field intensity, neodymium magnets offer the following advantages:

They retain full power for around ten years – the drop is just ~1% (in theory),
They are extremely resistant to demagnetization induced by presence of other magnetic fields,
By covering with a shiny layer of silver, the element has an elegant look,
Neodymium magnets ensure maximum magnetic induction on a their surface, which increases force concentration,
Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling functioning at temperatures approaching 230°C and above...
Due to the ability of accurate molding and adaptation to individualized requirements, magnetic components can be manufactured in a wide range of shapes and sizes, which increases their versatility,
Key role in high-tech industry – they are commonly used in magnetic memories, electric motors, precision medical tools, as well as modern systems.
Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,

Limitations

What to avoid - cons of neodymium magnets and proposals for their use:

Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a strong case, which not only secures them against impacts but also increases their durability
NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening 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 very resistant to heat
When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
We recommend a housing - magnetic mount, due to difficulties in creating threads inside the magnet and complex forms.
Possible danger to health – tiny shards of magnets pose a threat, in case of ingestion, which is particularly important in the context of child safety. Furthermore, small elements of these devices are able to complicate diagnosis medical when they are in 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 force for a neodymium magnet – what contributes to it?

The declared magnet strength refers to the peak performance, measured under laboratory conditions, specifically:

with the contact of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
whose transverse dimension is min. 10 mm
characterized by smoothness
without any insulating layer between the magnet and steel
for force acting at a right angle (in the magnet axis)
at room temperature

Impact of factors on magnetic holding capacity in practice

In real-world applications, the actual lifting capacity results from a number of factors, ranked from most significant:

Gap between magnet and steel – every millimeter of distance (caused e.g. by varnish or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
Force direction – declared lifting capacity refers to detachment vertically. When slipping, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
Steel thickness – too thin steel does not accept the full field, causing part of the flux to be wasted to the other side.
Steel grade – the best choice is high-permeability steel. Cast iron may have worse magnetic properties.
Surface quality – the more even the surface, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
Thermal environment – heating the magnet results in weakening of induction. Check the thermal limit for a given model.

Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under shearing force the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate lowers the load capacity.

Warnings

Demagnetization risk

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

Medical implants

Health Alert: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.

Magnet fragility

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

Fire warning

Drilling and cutting of NdFeB material carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.

Choking Hazard

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

Avoid contact if allergic

Medical facts indicate that the nickel plating (standard magnet coating) is a potent allergen. If you have an allergy, prevent touching magnets with bare hands or opt for versions in plastic housing.

Data carriers

Device Safety: Strong magnets can damage payment cards and sensitive devices (pacemakers, hearing aids, timepieces).

Crushing risk

Danger of trauma: The attraction force is so great that it can result in hematomas, pinching, and broken bones. Use thick gloves.

Respect the power

Use magnets consciously. Their immense force can surprise even experienced users. Be vigilant and respect their force.

Keep away from electronics

GPS units and smartphones are extremely sensitive to magnetic fields. Direct contact with a strong magnet can decalibrate the sensors in your phone.
