Grip strength decreases drastically with every mm of distance. Remember that even a very thin break (e.g., dirt, paint, dust) noticeably diminishes the holding power. Neodymiums operate strongest at the point of direct contact; air break drastically cuts the force. Analyze how rapidly the parameters plummet, when the product does not adhere directly to the metal substrate. When planning the assembly, discard redundant distances.

The following data defines the estimated shear load necessary to start the slippage of the magnet down along a upright steel plate (considering standard friction). The holding force depends on the gap size between the magnet and the metal.

Table 3: Wall mounting (shearing) - vertical pull

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)

Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.54 kg / 3.40 LBS 1544.0 g / 15.1 N

Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	3.86 kg / 8.51 LBS 3860.0 g / 37.9 N

When mounting a holder on a upright plane (e.g., a board), it will only hold just about 1/5 of its nominal power. Gravity and a weak degree of grip mean that magnets move down faster than they pull off. Designing a hanger? Consider that the shear force is much weaker than the perpendicular breakaway force. On a smooth steel, the holder will slip down under a noticeably lighter load. Utilizing a rubberized coating can effectively raise the stability.

A too thin steel is not enough to absorb the full magnetic flux, which squanders power of the magnet. If you install a neodymium to a thin surface, the flux will penetrate right through and the pull force will drop sharply. To utilize the maximum of this neodymium's power, you need a suitably thick backing of steel. The saturation effect means that on sheet metal structures (e.g., thin profiles), the holder holds weaker. We suggest choosing the steel cross-section based on the following data.

Classic neodymiums irreversibly lose power past the thermal threshold. Protect against heat – heat can irreversibly damage this magnet. With every degree above norm, the neodymium's capacity momentarily decreases. Do not use this product near heat sources higher than its working range. Ignoring the limit will cause permanent loss of magnetic properties.

*Engineering note: Thermal stability is determined by both grade, but also on the magnet's shape. Flat magnets (low permeance coefficient) are more susceptible to demagnetization under lower heat stress than long magnets. The danger warning in the table indicates a risk of irreversible loss for this specific geometry.

Two magnets interact from a significantly greater distance than a magnet and sheet combination. Such a system of two magnets produces a massive flux and a wider radius of operation. Want to build a strong closure? Utilize two neodymiums instead of a neodymium and a striker plate. Remember that when bringing together two magnets, the impact force is extreme. The levitation is a bit weaker than the connection force, but still large.
*Field value for N-N configuration is approximately ~0 Gs at the midpoint between the magnets (due to field cancellation).
Important: Figures demonstrate sliding force of dual same magnets (friction ~0.15 for Ni-Ni coating).

Extremely neodym field poses a real danger to electronics and medical implants. These neodymiums generate a flux that destroys function of digital equipment. Notice: the unseen radiation penetrates the body and housings. Exceptional care must be taken by people with hearing aids and insulin pumps. Influence will be felt by: automatic timepieces, car keys, membranes, and screens. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

Neodymium magnets are very brittle – a collision with steel can result in shattering. Control the attraction moment – a magnet released freely becomes dangerous. Impact energy can destroy the magnet or injury to fingers. Always hold the magnet during installation so it doesn't hit violently against the steel surface. A contact at a velocity of dozens of km/h ends with a crack of the neodymium. Wear eye protection when handling 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!

Contrary to myths, water does not block the magnetic field. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Shear force

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

2. Steel thickness impact

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

3. Thermal stability

*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

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.

0.541 ZŁ brutto / pcs

Model MPL 25x12.5x5 / N38 features a flat shape and professional pulling force, making it a perfect solution for building separators and machines. This rectangular block with a force of 75.74 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 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 25x12.5x5 / 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 25x12.5x5 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. 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 workshop organization on strips and for advanced DIY and modeling projects, where precision and power count.

For mounting flat magnets MPL 25x12.5x5 / 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 (25x12.5 mm), which is ideal for flat mounting. 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. The key parameter here is the lifting capacity amounting to approximately 7.72 kg (force ~75.74 N), which, with such a compact shape, proves the high grade of the material. The product meets the standards for N38 grade magnets.

Advantages and disadvantages of rare earth magnets.

Advantages

Apart from their superior magnetic energy, neodymium magnets have these key benefits:

They virtually do not lose power, because even after ten years the performance loss is only ~1% (according to literature),
Neodymium magnets are characterized by remarkably resistant to demagnetization caused by magnetic disturbances,
The use of an aesthetic layer of noble metals (nickel, gold, silver) causes the element to present itself better,
The surface of neodymium magnets generates a powerful magnetic field – this is a distinguishing feature,
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...
Thanks to the ability of precise molding and customization to unique requirements, NdFeB magnets can be modeled in a broad palette of shapes and sizes, which makes them more universal,
Key role in modern industrial fields – they are utilized in HDD drives, electric motors, diagnostic systems, as well as multitasking production systems.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which makes them useful in miniature devices

Weaknesses

Disadvantages of NdFeB magnets:

They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
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 stability even at temperatures up to 230°C
They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
Due to limitations in creating nuts and complex shapes in magnets, we propose using casing - magnetic mechanism.
Potential hazard to health – tiny shards of magnets are risky, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that small elements of these devices can disrupt the diagnostic process medical after entering the body.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Holding force characteristics

Maximum magnetic pulling force – what affects it?

The declared magnet strength refers to the peak performance, recorded under ideal test conditions, namely:

on a block made of structural steel, optimally conducting the magnetic flux
whose transverse dimension equals approx. 10 mm
with a surface perfectly flat
with total lack of distance (without paint)
during detachment in a direction perpendicular to the mounting surface
in stable room temperature

Practical aspects of lifting capacity – factors

Effective lifting capacity is affected by working environment parameters, mainly (from most important):

Distance (betwixt the magnet and the plate), as even a tiny distance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
Loading method – catalog parameter refers to detachment vertically. When slipping, the magnet exhibits much less (typically approx. 20-30% of nominal force).
Steel thickness – insufficiently thick sheet does not close the flux, causing part of the power to be escaped to the other side.
Metal type – not every steel reacts the same. High carbon content worsen the attraction effect.
Smoothness – ideal contact is obtained only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
Thermal conditions – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and in frost gain strength (up to a certain limit).

Lifting capacity testing was carried out on a smooth plate of optimal thickness, under a perpendicular pulling force, whereas under parallel forces the load capacity is reduced by as much as 5 times. Additionally, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.

Safety rules for work with NdFeB magnets

Warning for allergy sufferers

It is widely known that nickel (standard magnet coating) is a strong allergen. If your skin reacts to metals, avoid direct skin contact or select versions in plastic housing.

Dust is flammable

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

Medical implants

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

Electronic devices

Do not bring magnets close to a wallet, laptop, or TV. The magnetism can permanently damage these devices and erase data from cards.

Powerful field

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

Keep away from electronics

GPS units and smartphones are extremely susceptible to magnetic fields. Close proximity with a strong magnet can ruin the internal compass in your phone.

Crushing risk

Pinching hazard: The attraction force is so great that it can result in blood blisters, pinching, and even bone fractures. Use thick gloves.

Magnet fragility

Beware of splinters. Magnets can fracture upon uncontrolled impact, ejecting shards into the air. Eye protection is mandatory.

This is not a toy

Strictly keep magnets away from children. Risk of swallowing is significant, and the effects of magnets clamping inside the body are life-threatening.

Permanent damage

Do not overheat. NdFeB magnets are susceptible to temperature. If you require operation above 80°C, inquire about HT versions (H, SH, UH).

Caution! Details about hazards in the article: Safety of working with magnets.
