Pulling power decreases drastically with every subsequent millimeter of gap. Remember that even a very thin break (e.g., contamination, paint, dust) noticeably diminishes the holding power. Magnetic products hold most effectively at the point of direct contact; distance weakens the power. Observe how rapidly the pull force drop, when the product does not adhere directly to the steel surface. When designing the mounting, avoid additional spacers.

The following data calculates the theoretical shear load required to initiate the shifting of the magnet down along a upright steel wall (assuming standard friction coefficient). This parameter varies with the air gap between the magnet and the surface.

Table 3: Wall mounting (shearing) - vertical pull

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	3.81 kg / 8.39 lbs 3807.0 g / 37.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	2.54 kg / 5.60 lbs 2538.0 g / 24.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	1.27 kg / 2.80 lbs 1269.0 g / 12.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	6.35 kg / 13.99 lbs 6345.0 g / 62.2 N

When hanging a element on a upright wall (e.g., a board), it will only hold barely about 1/5 of its maximum pull force. Gravitational force and a weak degree of grip influence the fact that holders move down faster than they pull off. Designing a wall mount? Remember that the shear force is noticeably lower than the perpendicular breakaway force. On a smooth steel, the holder will give way down under a significantly smaller cargo. Using a rubber pad can effectively increase the grip.

Steel thickness (mm)	% power	Real pull force (kg/lbs/g/N)
0.5 mm	5%	0.63 kg / 1.40 lbs 634.5 g / 6.2 N

3 mm	38%	4.76 kg / 10.49 lbs 4758.8 g / 46.7 N
5 mm	63%	7.93 kg / 17.49 lbs 7931.2 g / 77.8 N
10 mm	100%	12.69 kg / 27.98 lbs 12690.0 g / 124.5 N
11 mm	100%	12.69 kg / 27.98 lbs 12690.0 g / 124.5 N
12 mm	100%	12.69 kg / 27.98 lbs 12690.0 g / 124.5 N

A too thin steel is unable to focus the full magnetic flux, which squanders power of the holder. If you mount a strong magnet to a too thin substrate, the flux will penetrate right through and the pull force will drop sharply. To achieve the maximum of this magnet's potential, you require a sufficiently solid piece of steel. The saturation effect means that on thin elements (e.g., car bodies), the product holds weaker. We recommend selecting the steel thickness from these parameters.

Standard neodymium magnets change their properties power after exceeding the maximum temperature. Watch out for overheating – excessive heat can irreversibly demagnetize this product. As the temperature rises, the neodymium's force momentarily lowers. Avoid using this magnet close to ovens higher than its operating temperature limit. Exceeding the critical threshold will lead to permanent loss of magnetism.

*Engineering note: Heat tolerance depends not only on the material grade, and the Permeance Coefficient Pc. Thin magnets (low permeance coefficient) may lose charge permanently under lower heat stress compared to rod magnets. Warning indicator in the table indicates permanent field degradation for this specific geometry.

Two magnets attract each other from a significantly greater 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? Utilize two neodymiums instead of a neodymium and a steel. Remember that when bringing together two magnets, the pinch force is massive. The repulsion force is slightly lower than the attraction, but still large.
*Flux density for N-N configuration reaches ~0 Gs at the geometric center of the gap (due to field cancellation).
Attention: Figures demonstrate shear force of a pair of identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

Table 7: Protective zones (electronics) - warnings

A strong magnetic field poses a real danger to IT equipment as well as pacemakers. These neodymiums produce a flux that destroys function of digital equipment. Remember: the unseen radiation passes through tissues and glass. Increased vigilance must be exercised by people with hearing aids and insulin pumps. Also at risk are: automatic timepieces, remotes, membranes, and displays. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Table 8: Collisions (cracking risk) - warning

Magnetic elements are delicate – a violent impact against metal risks their cracking. Watch the impact speed – a neodymium left loose turns into a projectile. Impact energy can cause material chips or dangerous crushing to skin. Hold the magnet firmly during mounting so it doesn't hit violently against the metal. A collision at high speed almost guarantees destruction of the neodymium. Use safety goggles when working with powerful specimens.

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

1. Vertical hold

*Caution: On a vertical wall, the magnet holds just ~20% of its perpendicular strength.

2. Efficiency vs thickness

*Thin metal sheet (e.g. 0.5mm PC case) drastically weakens the holding force.

3. Heat tolerance

*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) = 0.21

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 a very powerful magnet in the shape of a plate made of NdFeB material, which, with dimensions of 50x20x5 mm and a weight of 37.5 g, guarantees the highest quality connection. This magnetic block with a force of 124.48 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 50x20x5 / N38 model, firmly slide one magnet over the edge of the other until the attraction force decreases. We recommend extreme caution, 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 50x20x5 / N38 are the foundation for many industrial devices, such as filters catching filings and linear motors. They work great as invisible mounts under tiles, wood, or glass. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.

For mounting flat magnets MPL 50x20x5 / 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 50x20x5 / N38 model is magnetized axially (dimension 5 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: 50 mm (length), 20 mm (width), and 5 mm (thickness). It is a magnetic block with dimensions 50x20x5 mm and a self-weight of 37.5 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Strengths as well as weaknesses of Nd₂Fe₁₄B magnets.

Advantages

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

Their magnetic field is durable, and after approximately 10 years it drops only by ~1% (according to research),
They do not lose their magnetic properties even under external field action,
By covering with a shiny coating of gold, the element presents an nice look,
Magnets are characterized by maximum magnetic induction on the outer layer,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
In view of the potential of flexible shaping and customization to individualized needs, neodymium magnets can be manufactured in a variety of forms and dimensions, which makes them more universal,
Universal use in modern industrial fields – they find application in magnetic memories, brushless drives, advanced medical instruments, also technologically advanced constructions.
Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,

Weaknesses

Problematic aspects of neodymium magnets: application proposals

To avoid cracks under impact, we recommend using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (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
Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
Due to limitations in producing threads and complex shapes in magnets, we propose using a housing - magnetic mechanism.
Possible danger related to microscopic parts of magnets pose a threat, in case of ingestion, which is particularly important in the context of child health protection. It is also worth noting that small elements of these products are able to disrupt the diagnostic process medical when they are in the body.
With budget limitations the cost of neodymium magnets is a challenge,

Holding force characteristics

Optimal lifting capacity of a neodymium magnet – what affects it?

Holding force of 12.69 kg is a measurement result performed under the following configuration:

on a block made of mild steel, optimally conducting the magnetic field
possessing a thickness of minimum 10 mm to ensure full flux closure
with an ideally smooth contact surface
without the slightest clearance between the magnet and steel
during detachment in a direction perpendicular to the mounting surface
in stable room temperature

What influences lifting capacity in practice

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

Air gap (betwixt the magnet and the metal), because even a microscopic clearance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
Steel type – mild steel gives the best results. Alloy admixtures decrease magnetic permeability and holding force.
Smoothness – full contact is possible only on polished steel. Any scratches and bumps create air cushions, reducing force.
Temperature – temperature increase results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.

Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under shearing force the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet and the plate reduces the holding force.

Safe handling of NdFeB magnets

Crushing force

Protect your hands. Two large magnets will snap together instantly with a force of massive weight, crushing everything in their path. Exercise extreme caution!

Respect the power

Before starting, read the rules. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.

Do not overheat magnets

Regular neodymium magnets (N-type) lose power when the temperature exceeds 80°C. The loss of strength is permanent.

Material brittleness

Despite metallic appearance, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may crumble into hazardous fragments.

Phone sensors

Note: rare earth magnets generate a field that disrupts sensitive sensors. Keep a safe distance from your phone, device, and navigation systems.

Mechanical processing

Machining of NdFeB material carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.

Do not give to children

These products are not intended for children. Swallowing multiple magnets can lead to them connecting inside the digestive tract, which constitutes a severe health hazard and necessitates immediate surgery.

Danger to pacemakers

Individuals with a ICD should keep an absolute distance from magnets. The magnetic field can disrupt the functioning of the implant.

Threat to electronics

Device Safety: Strong magnets can ruin data carriers and sensitive devices (pacemakers, hearing aids, mechanical watches).

Sensitization to coating

Medical facts indicate that the nickel plating (the usual finish) is a strong allergen. If your skin reacts to metals, avoid touching magnets with bare hands or opt for encased magnets.
