Grip strength drops sharply per each millimeter of distance. Keep in mind that even a microscopic distance (e.g., contamination, varnish, dust) significantly diminishes the holding power. Magnetic products hold optimally at the point of direct contact; gap drastically cuts the force. Analyze how quickly the load capacity plummet, when the product does not touch flatly to the steel surface. When planning the arrangement, eliminate redundant distances.

The following data shows the theoretical weight limit required to start the sliding of the magnet vertically along a vertical steel wall (assuming typical friction). This parameter is relative to the gap size between the magnet and the metal.

Table 3: Vertical assembly (shearing) - vertical pull

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	2.32 kg / 5.11 lbs 2316.0 g / 22.7 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 magnet on a vertical wall (e.g., a board), it will maintain only approx. 20%-30% of nominal attraction strength. Gravity as well as a weak degree of grip mean that products slide down easier than they pull off. Planning a wall mount? Remember that the sliding force is significantly lower than the maximum static pull force. On a slippery surface, the element will give way down under a noticeably lighter load. Using a rubber layer can effectively increase the grip.

A thin metal plate is unable to focus the full magnetic flux, which squanders power of the holder. If you mount a strong magnet to a weak sheet, the magnetism will pass right through and the holding will be smaller. To squeeze full efficiency of this neodymium's power, you need a suitably thick element of metal. The saturation effect means that on sheet metal structures (e.g., appliance housings), the magnet holds weaker. We suggest choosing the steel dimension based on the following data.

Ordinary NdFeB products change their properties parameters after exceeding the maximum temperature. Avoid high temperatures – heat can irreversibly demagnetize this product. With increasing heat, the neodymium's capacity momentarily decreases. Do not use this product near heat sources higher than its operating temperature limit. Too high temperature will lead to destruction of magnetic properties.

*Engineering note: Thermal stability depends not only on the material grade, and the Permeance Coefficient Pc. Low-profile magnets (low Pc) are more susceptible to demagnetization sooner compared to rod magnets. Warning indicator in the table indicates permanent field degradation for this particular item.

Two magnets attract each other from a wider radius than a neodymium and metal setup. The connection of two magnets generates a stronger field and a wider radius of action. Designing a powerful holder? Apply two magnets instead of one magnet and a striker plate. Be careful that when connecting a pair of magnets, the pinch force is massive. The repulsion force is a bit weaker than the connection force, but still impressive.
*The magnetic induction for N-N configuration drops to ~0 Gs at the geometric center of the gap (resulting from vector opposition).
Attention: Results demonstrate sliding force of two identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

Powerful magnet radiation is a real danger to electronic devices as well as medical implants. These NdFeB products produce a field that disrupts operation of sensitive medical devices. Notice: the unseen radiation penetrates the body and housings. Special caution must be exercised by people with cochlear implants and drug dispensers. The risk also applies to: automatic timepieces, car keys, speakers, and screens. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Magnetic elements are prone to chipping – a strong collision with metal can result in shattering. Watch the impact speed – a neodymium left loose speeds with massive force. Impact energy can cause material chips or painful pinches to skin. Hold the magnet firmly during bringing near metal so it doesn't hit violently against the metal. A contact at a velocity of dozens of km/h ends with a crack of the magnet. Wear safety glasses when handling with large magnets.

Warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

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

1. Shear force

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

2. Steel thickness impact

*Thin metal sheet (e.g. 0.5mm PC case) severely 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) = 0.35

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.

This product is a very powerful magnet in the shape of a plate made of NdFeB material, which, with dimensions of 25x12.5x5 mm and a weight of 11.72 g, guarantees premium class connection. This rectangular block with a force of 75.74 N is ready for shipment in 24h, allowing for rapid realization of your project. Additionally, its Ni-Cu-Ni coating protects it against corrosion in standard operating conditions, giving it an aesthetic appearance.

Separating strong flat magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. 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. 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 25x12.5x5 / N38, we recommend utilizing two-component adhesives (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 roughen and wash the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

Standardly, the MPL 25x12.5x5 / N38 model is magnetized axially (dimension 5 mm), which means that the N and S poles are located on its largest, flat surfaces. 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. 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), 12.5 mm (width), and 5 mm (thickness). The key parameter here is the holding force 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 neodymium magnets.

Benefits

Besides their high retention, neodymium magnets are valued for these benefits:

They do not lose strength, even over nearly ten years – the reduction in power is only ~1% (based on measurements),
Neodymium magnets remain remarkably resistant to loss of magnetic properties caused by magnetic disturbances,
Thanks to the reflective finish, the layer of nickel, gold, or silver gives an visually attractive appearance,
The surface of neodymium magnets generates a concentrated magnetic field – this is a distinguishing feature,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
Thanks to modularity in constructing and the capacity to modify to complex applications,
Universal use in future technologies – they are commonly used in magnetic memories, electromotive mechanisms, diagnostic systems, and industrial machines.
Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,

Weaknesses

Disadvantages of NdFeB magnets:

They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only protects the magnet but also increases its resistance to damage
We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
Magnets exposed to a humid environment can rust. Therefore when using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
Limited ability of making threads in the magnet and complicated shapes - recommended is a housing - magnet mounting.
Health risk resulting from small fragments of magnets are risky, if swallowed, which gains importance in the context of child safety. It is also worth noting that small components of these products are able to complicate diagnosis medical after entering the body.
With mass production the cost of neodymium magnets is a challenge,

Pull force analysis

Breakaway strength of the magnet in ideal conditions – what contributes to it?

Information about lifting capacity was defined for optimal configuration, assuming:

using a plate made of mild steel, functioning as a circuit closing element
with a cross-section of at least 10 mm
with a surface perfectly flat
without the slightest clearance between the magnet and steel
for force acting at a right angle (in the magnet axis)
at conditions approx. 20°C

Key elements affecting lifting force

During everyday use, the actual lifting capacity is determined by several key aspects, presented from most significant:

Distance – the presence of foreign body (paint, tape, air) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
Plate material – mild steel attracts best. Alloy admixtures reduce magnetic permeability and lifting capacity.
Smoothness – ideal contact is possible only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
Thermal environment – temperature increase results in weakening of force. Check the thermal limit for a given model.

Lifting capacity testing was conducted on a smooth plate of optimal thickness, under perpendicular forces, however under parallel forces the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate decreases the holding force.

Warnings

Electronic hazard

Very strong magnetic fields can destroy records on payment cards, hard drives, and other magnetic media. Maintain a gap of min. 10 cm.

Compass and GPS

GPS units and mobile phones are extremely susceptible to magnetism. Close proximity with a strong magnet can permanently damage the sensors in your phone.

Allergy Warning

It is widely known that nickel (standard magnet coating) is a common allergen. If you have an allergy, refrain from direct skin contact or opt for coated magnets.

Risk of cracking

Protect your eyes. Magnets can explode upon uncontrolled impact, launching shards into the air. We recommend safety glasses.

Combustion hazard

Dust produced during cutting of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.

Handling guide

Exercise caution. Rare earth magnets act from a distance and snap with massive power, often faster than you can move away.

Permanent damage

Keep cool. Neodymium magnets are sensitive to temperature. If you require resistance above 80°C, look for special high-temperature series (H, SH, UH).

Medical interference

For implant holders: Strong magnetic fields affect electronics. Maintain minimum 30 cm distance or ask another person to handle the magnets.

Do not give to children

Always keep magnets out of reach of children. Risk of swallowing is high, and the effects of magnets clamping inside the body are fatal.

Pinching danger

Pinching hazard: The attraction force is so immense that it can cause hematomas, pinching, and even bone fractures. Protective gloves are recommended.

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