Pulling power weakens sharply per each millimeter of gap. Keep in mind that every additional insulation layer (e.g., contamination, varnish, veneer) noticeably weakens the grip. Magnets work most effectively during direct contact; air break kills the force. Analyze how flashily the load capacity drop, when the product does not touch directly to the steel surface. When designing the arrangement, avoid redundant distances.

This section shows the theoretical holding capacity required to initiate the sliding of the magnet vertically along a vertical steel plate (considering standard friction coefficient). This parameter depends on the gap size between the magnet and the surface.

Table 3: Vertical assembly (shearing) - vertical pull
MPL 25x12.5x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	2.32 kg / 5.11 pounds 2316.0 g / 22.7 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.54 kg / 3.40 pounds 1544.0 g / 15.1 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.77 kg / 1.70 pounds 772.0 g / 7.6 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	3.86 kg / 8.51 pounds 3860.0 g / 37.9 N

When placing a element on a vertical wall (e.g., a fridge), it will only hold only about 1/5 of its maximum pull force. Gravity as well as a weak degree of grip mean that products slip faster than they detach. Want to create a hanger? Note that the shear force is significantly lower than the perpendicular breakaway force. On a smooth steel, the holder will slide down under a significantly smaller cargo. Application of an anti-slip pad can effectively increase the grip.

12 mm	100%	7.72 kg / 17.02 pounds 7720.0 g / 75.7 N

A too thin steel cannot focus the full magnetic flux, which wastes potential of the holder. If you mount a strong magnet to a thin surface, the magnetism will pass right through and the pull force will drop sharply. To squeeze the maximum of this neodymium's power, you need a suitably thick element of steel. The saturation phenomenon causes that on sheet metal structures (e.g., thin profiles), the magnet holds weaker. We recommend selecting the steel thickness according to the table below.

Standard neodymium magnets irreversibly lose power past the thermal threshold. Watch out for overheating – excessive heat can permanently demagnetize this product. With every degree above norm, the neodymium's force temporarily lowers. Avoid using this magnet in hot environments higher than its operating temperature limit. Exceeding the critical threshold will cause permanent loss of magnetism.

*Engineering note: Heat tolerance depends not only on the material grade, but also on the magnet's shape. Flat magnets (low Pc) may lose charge permanently under lower heat stress than long magnets. Red status in the table indicates a risk of irreversible loss for this particular item.

Two magnets attract each other from a much further distance than a magnet and steel combination. The setup of two magnets produces a massive flux and a wider radius of action. Planning to create a strong closure? Use a pair of magnets instead of a neodymium and a steel. Exercise caution that when attracting two neodymiums, the impact force is extreme. The levitation is slightly lower than the connection force, but still significant.
*Flux density in repulsion mode drops to ~0 Gs in the exact middle between the magnets (caused by magnetic field nullification).
* Results refer to sliding force of two matching magnets (friction ~0.15 for Ni-Ni coating).

Extremely neodym field poses a real danger to IT equipment as well as medical implants. These magnets generate a field that prevents correct functioning of digital equipment. Remember: the invisible magnetic field passes through tissues and plastic. Special caution must be taken by people with hearing aids and insulin pumps. The risk also applies to: automatic timepieces, remotes, membranes, and screens. Do not bring the product near payment cards, HDD media, or precise measuring instruments.

NdFeB products are very brittle – a collision with steel risks their cracking. Pay attention to connection velocity – a magnet released freely turns into a projectile. Impact energy can destroy the magnet or dangerous crushing to fingers. Always hold the magnet during bringing near metal so it doesn't hit violently against the steel surface. A collision at high speed ends with a crack of the neodymium. Wear eye protection when working with powerful specimens.

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

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

1. Vertical hold

*Note: On a vertical wall, the magnet retains merely approx. 20-30% of its max power.

2. Steel saturation

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

3. Heat tolerance

*For standard magnets, the safety limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.35

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 25x12.5x5 mm and a weight of 11.72 g, guarantees the highest quality connection. As a block magnet with high power (approx. 7.72 kg), this product is available immediately from our warehouse in Poland. The durable anti-corrosion layer ensures a long lifespan in a dry environment, protecting the core from oxidation.

Separating strong flat magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. Watch your fingers! Magnets with a force of 7.72 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 wind generators and material handling systems. Thanks to the flat surface and high force (approx. 7.72 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.

For mounting flat magnets MPL 25x12.5x5 / N38, it is best to use 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 roughen and wash 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. This is the most popular configuration for block magnets used in separators and holders.

This model is characterized by dimensions 25x12.5x5 mm, which, at a weight of 11.72 g, makes it an element with high energy density. It is a magnetic block with dimensions 25x12.5x5 mm and a self-weight of 11.72 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Advantages and disadvantages of Nd₂Fe₁₄B magnets.

Pros

In addition to their long-term stability, neodymium magnets provide the following advantages:

Their power remains stable, and after around 10 years it decreases only by ~1% (according to research),
Neodymium magnets are characterized by extremely resistant to magnetic field loss caused by external interference,
In other words, due to the shiny layer of silver, the element becomes visually attractive,
The surface of neodymium magnets generates a maximum magnetic field – this is a distinguishing feature,
Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures approaching 230°C and above...
Thanks to modularity in designing and the capacity to modify to unusual requirements,
Universal use in electronics industry – they are commonly used in HDD drives, motor assemblies, precision medical tools, and complex engineering applications.
Thanks to their power density, small magnets offer high operating force, occupying minimum space,

Limitations

Cons of neodymium magnets: weaknesses and usage proposals

At very strong impacts they can crack, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
Neodymium magnets lose their power 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 stability even at temperatures up to 230°C
They rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
Due to limitations in creating threads and complicated forms in magnets, we recommend using cover - magnetic mechanism.
Possible danger to health – tiny shards of magnets can be dangerous, if swallowed, which is particularly important in the context of child safety. Furthermore, small components of these devices can disrupt the diagnostic process medical when they are in the body.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Lifting parameters

Maximum lifting capacity of the magnet – what contributes to it?

The load parameter shown refers to the limit force, recorded under optimal environment, namely:

on a block made of mild steel, optimally conducting the magnetic flux
whose thickness is min. 10 mm
characterized by even structure
under conditions of no distance (surface-to-surface)
for force applied at a right angle (in the magnet axis)
at standard ambient temperature

Impact of factors on magnetic holding capacity in practice

Bear in mind that the working load will differ depending on the following factors, starting with the most relevant:

Air gap (betwixt the magnet and the metal), since even a microscopic clearance (e.g. 0.5 mm) can cause a drastic drop in lifting capacity by up to 50% (this also applies to paint, rust or debris).
Angle of force application – maximum parameter is reached only during perpendicular pulling. The shear force of the magnet along the surface is standardly many times smaller (approx. 1/5 of the lifting capacity).
Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of generating force.
Steel grade – ideal substrate is pure iron steel. Hardened steels may have worse magnetic properties.
Plate texture – smooth surfaces ensure maximum contact, which increases field saturation. Rough surfaces weaken the grip.
Thermal conditions – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).

Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under perpendicular forces, however under shearing force the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the load capacity.

Safe handling of neodymium magnets

GPS Danger

Be aware: neodymium magnets generate a field that confuses precision electronics. Keep a safe distance from your phone, tablet, and navigation systems.

Warning for heart patients

Medical warning: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.

Adults only

Adult use only. Tiny parts pose a choking risk, causing serious injuries. Store out of reach of kids and pets.

Heat sensitivity

Regular neodymium magnets (N-type) lose magnetization when the temperature exceeds 80°C. This process is irreversible.

Magnets are brittle

Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.

Handling guide

Before use, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.

Allergy Warning

It is widely known that nickel (the usual finish) is a strong allergen. If you have an allergy, prevent direct skin contact or select versions in plastic housing.

Hand protection

Mind your fingers. Two large magnets will join instantly with a force of massive weight, destroying anything in their path. Exercise extreme caution!

Flammability

Dust generated during grinding of magnets is flammable. Do not drill into magnets unless you are an expert.

Data carriers

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

Caution! Learn more about risks in the article: Magnet Safety Guide.
