Pulling power decreases significantly per each millimeter of spacing. Remember that every additional insulation layer (e.g., contamination, varnish, dust) noticeably reduces the pull force. Neodymiums operate strongest at the point of direct contact; air break drastically cuts the force. Notice how quickly the pull force fall, when the magnet does not adhere tightly to the metal substrate. When calculating the assembly, discard redundant distances.

The table below presents the approximate shear load sufficient to cause the downward movement of the magnet down against a vertical steel plate (considering typical friction). This value is relative to the gap size between the magnet and the surface.

Table 3: Vertical assembly (sliding) - vertical pull
MPL 25x10x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	2.25 kg / 4.95 lbs 2247.0 g / 22.0 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.50 kg / 3.30 lbs 1498.0 g / 14.7 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.75 kg / 1.65 lbs 749.0 g / 7.3 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	3.75 kg / 8.26 lbs 3745.0 g / 36.7 N

When mounting a magnet on a upright wall (e.g., a board), it you can count on barely approx. 20%-30% of its maximum pull force. Gravity as well as a low friction coefficient influence the fact that magnets slip faster than they detach. Planning a vertical fastening? Consider that the shear force is significantly lower than the maximum static pull force. On a painted metal, the magnet will give way down under a much lighter cargo. Using a rubber coating can significantly increase the grip.

12 mm	100%	7.49 kg / 16.51 lbs 7490.0 g / 73.5 N

A too thin steel is unable to absorb the entire magnetic field, which weakens actual performance of the holder. If you install a neodymium to a thin surface, the magnetism will penetrate right through and the attraction force will be weaker. To utilize 100% of this neodymium's potential, you require a sufficiently solid piece of steel. The saturation effect means that on thin elements (e.g., thin profiles), the holder shows lower pull force. We recommend selecting the steel dimension from these parameters.

Classic neodymiums change their properties parameters after exceeding the maximum temperature. Watch out for overheating – high temperature can irreversibly demagnetize this magnet. As the temperature rises, the neodymium's capacity momentarily decreases. Do not use this magnet close to heaters exceeding its working range. Too high temperature will result in destruction of magnetism.

*Engineering note: Heat tolerance depends not only on the material grade, as well as the dimension ratios. Thin magnets (low Pc) may lose charge permanently at lower temperatures than taller cylinders. Red status in the table signals permanent field degradation for this specific geometry.

Two strong neodymiums interact from a wider radius than a magnet and sheet setup. The connection of two magnets creates a more powerful interaction and a further horizon of action. Planning to create a strong closure? Utilize two neodymiums instead of one magnet and a striker plate. Exercise caution that when bringing together two magnets, the collision energy is huge. The levitation is slightly lower than the connection force, but still large.
*The magnetic induction for N-N configuration is approximately ~0 Gs at the geometric center of the gap (due to field cancellation).
Note: Results apply to friction force of a pair of matching magnets (friction coefficient ~0.15 for Ni-Ni plating).

A strong magnetic field is a serious hazard to IT equipment and medical implants. These neodymiums produce a field that destroys function of digital equipment. Be aware: the unseen radiation passes through tissues and housings. Exceptional care must be exercised by people with hearing aids and insulin pumps. Also at risk are: mechanical watches, car keys, membranes, and displays. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

Table 8: Impact energy (cracking risk) - warning

100 mm	90.12 km/h (25.03 m/s)	2.94 J

Neodymium magnets are very brittle – a collision with steel risks their cracking. Control the attraction moment – a magnet released freely turns into a projectile. Impact energy can destroy the magnet or dangerous crushing to fingers. Be sure to control the product during installation so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Wear eye protection when handling with large magnets.

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

In water, the magnet feels stronger thanks to Archimedes' principle. However, remember the water resistance when pulling the rope quickly.

1. Vertical hold

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

2. Plate thickness effect

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

3. Temperature resistance

*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) = 0.38

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.

KM HF - 34,5 kg - magnetic bracket

34.44 ZŁ brutto / pcs

This product is an extremely strong magnet in the shape of a plate made of NdFeB material, which, with dimensions of 25x10x5 mm and a weight of 9.38 g, guarantees the highest quality connection. This rectangular block with a force of 73.45 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. Watch your fingers! Magnets with a force of 7.49 kg can pinch very hard and cause hematomas. Never use metal tools for prying, as the brittle NdFeB material may chip and damage your eyes.

They constitute a key element in the production of generators and material handling systems. Thanks to the flat surface and high force (approx. 7.49 kg), they are ideal as hidden locks in furniture making and mounting elements in automation. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.

For mounting flat magnets MPL 25x10x5 / N38, we recommend utilizing strong epoxy glues (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. 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. Thanks to this, it works best when "sticking" to sheet metal or another magnet with a large surface area. 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: 25 mm (length), 10 mm (width), and 5 mm (thickness). The key parameter here is the holding force amounting to approximately 7.49 kg (force ~73.45 N), which, with such a compact shape, proves the high power of the material. The product meets the standards for N38 grade magnets.

Strengths and weaknesses of neodymium magnets.

Benefits

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

They retain attractive force for nearly 10 years – the loss is just ~1% (based on simulations),
They are resistant to demagnetization induced by external disturbances,
The use of an metallic finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
Magnetic induction on the top side of the magnet turns out to be maximum,
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...
Possibility of custom modeling as well as adapting to complex applications,
Significant place in innovative solutions – they are utilized in data components, electromotive mechanisms, precision medical tools, also technologically advanced constructions.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Weaknesses

Problematic aspects of neodymium magnets and proposals for their use:

At strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
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 prevent oxidation and corrosion.
We recommend cover - magnetic mechanism, due to difficulties in creating nuts inside the magnet and complex forms.
Health risk resulting from small fragments of magnets are risky, if swallowed, which gains importance in the context of child health protection. It is also worth noting that small components of these magnets can disrupt the diagnostic process medical after entering the body.
With large orders the cost of neodymium magnets is a challenge,

Pull force analysis

Maximum magnetic pulling force – what contributes to it?

Breakaway force was determined for optimal configuration, taking into account:

with the contact of a sheet made of low-carbon steel, ensuring full magnetic saturation
whose transverse dimension is min. 10 mm
with a plane perfectly flat
without the slightest insulating layer between the magnet and steel
during detachment in a direction perpendicular to the mounting surface
at room temperature

What influences lifting capacity in practice

It is worth knowing that the application force may be lower subject to the following factors, starting with the most relevant:

Air gap (betwixt the magnet and the plate), because even a tiny distance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
Force direction – declared lifting capacity refers to detachment vertically. When slipping, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
Metal type – different alloys reacts the same. Alloy additives weaken the interaction with the magnet.
Surface structure – the more even the surface, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
Heat – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity was assessed using a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under parallel forces the holding force is lower. Additionally, even a slight gap between the magnet’s surface and the plate decreases the load capacity.

Safety rules for work with neodymium magnets

Medical interference

Individuals with a ICD have to keep an absolute distance from magnets. The magnetism can stop the functioning of the implant.

Adults only

NdFeB magnets are not toys. Eating multiple magnets may result in them connecting inside the digestive tract, which constitutes a critical condition and necessitates urgent medical intervention.

Nickel allergy

Studies show that the nickel plating (the usual finish) is a potent allergen. If you have an allergy, avoid touching magnets with bare hands and select encased magnets.

Respect the power

Exercise caution. Rare earth magnets attract from a distance and connect with huge force, often quicker than you can move away.

Data carriers

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

Risk of cracking

Neodymium magnets are sintered ceramics, meaning they are fragile like glass. Impact of two magnets will cause them shattering into small pieces.

Heat sensitivity

Standard neodymium magnets (grade N) lose power when the temperature surpasses 80°C. Damage is permanent.

Impact on smartphones

An intense magnetic field interferes with the operation of compasses in smartphones and navigation systems. Do not bring magnets close to a device to avoid breaking the sensors.

Bodily injuries

Big blocks can crush fingers instantly. Under no circumstances put your hand between two strong magnets.

Fire risk

Fire hazard: Neodymium dust is explosive. Do not process magnets without safety gear as this risks ignition.

Danger! Details about risks in the article: Magnet Safety Guide.
