Grip strength weakens significantly per each millimeter of distance. Keep in mind that every additional insulation layer (e.g., contamination, varnish, rust) significantly diminishes the holding power. Magnets operate optimally during direct contact; gap weakens the force. Observe how flashily the pull force fall, when the product does not adhere directly to the steel surface. When planning the arrangement, eliminate additional spacers.

The table below shows the approximate weight limit sufficient to cause the shifting of the magnet down against a vertical steel plate (considering typical friction). The holding force depends on the distance between the magnet and the metal.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces
MPL 50x25x12 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg)
Raw steel	µ = 0.3 30% Nominalnej Siły	11.14 kg / 11136.0 g 109.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	7.42 kg / 7424.0 g 72.8 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	3.71 kg / 3712.0 g 36.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	18.56 kg / 18560.0 g 182.1 N

When hanging a element on a vertical plane (e.g., a fridge), it will maintain just approx. 1/5 of nominal attraction strength. Gravitational force as well as a weak degree of grip cause that holders slide down faster than they pull off. Designing a hanger? Remember that the shear force is noticeably lower than the maximum static pull force. On a painted metal, the holder will slide down under a significantly smaller cargo. Application of an anti-slip coating can effectively improve the result.

Table 4: Material efficiency (substrate influence) - sheet metal selection
MPL 50x25x12 / N38

Steel thickness (mm)	% power	Real pull force (kg)
0.5 mm	5%	1.86 kg / 1856.0 g 18.2 N
1 mm	13%	4.64 kg / 4640.0 g 45.5 N
2 mm	25%	9.28 kg / 9280.0 g 91.0 N

10 mm	100%	37.12 kg / 37120.0 g 364.1 N

A thin metal plate cannot absorb the full magnetic flux, which wastes potential of the holder. If you install a neodymium to a weak sheet, the magnetism will penetrate right through and the attraction force will be weaker. To squeeze the maximum of this magnet's power, you need a suitably thick backing of steel. The material oversaturation causes that on delicate walls (e.g., appliance housings), the holder shows lower pull force. We suggest choosing the steel dimension according to the table below.

Table 5: Working in heat (stability) - power drop
MPL 50x25x12 / N38

Ordinary NdFeB products change their properties strength past the thermal threshold. Avoid high temperatures – heat can permanently demagnetize this product. With every degree above norm, the neodymium's capacity momentarily lowers. Avoid using this magnet close to ovens exceeding its safe range. Ignoring the limit will result in irreversible degradation of magnetic properties.

*Technical advisory: Temperature resistance is determined by both grade, as well as the dimension ratios. Low-profile magnets (low Pc) may lose charge permanently sooner compared to rod magnets. Warning indicator in the table indicates permanent field degradation for this specific geometry.

Two strong neodymiums interact from a wider radius than a magnet and steel combination. The setup of magnet-to-magnet produces a massive flux and a larger range of operation. Want to build a solid fastener? Use a pair of magnets instead of one magnet and a striker plate. Be careful that when bringing together two magnets, the impact force is massive. The repulsion force is marginally weaker than the connection force, but still significant.
*The magnetic induction for N-N configuration drops to ~0 Gs at the geometric center between the magnets (caused by magnetic field nullification).

Table 7: Hazards (electronics) - precautionary measures
MPL 50x25x12 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	17.5 cm
Hearing aid	10 Gs (1.0 mT)	14.0 cm
Mechanical watch	20 Gs (2.0 mT)	11.0 cm

A strong magnetic field poses a serious hazard to IT equipment and pacemakers. These neodymiums generate a field that prevents correct functioning of sensitive medical devices. Notice: the unseen radiation passes through tissues and plastic. Exceptional care must be exercised by people with cochlear implants and drug dispensers. Also at risk are: mechanical watches, remotes, speakers, and screens. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Table 8: Collisions (cracking risk) - collision effects
MPL 50x25x12 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	20.99 km/h (5.83 m/s)	1.91 J
30 mm	32.01 km/h (8.89 m/s)	4.45 J
50 mm	41.00 km/h (11.39 m/s)	7.30 J
100 mm	57.93 km/h (16.09 m/s)	14.57 J

Magnetic elements are delicate – a strong collision with metal risks their cracking. Pay attention to connection velocity – a neodymium left loose becomes dangerous. Striking energy can destroy the magnet or painful pinches to skin. Be sure to control the product during bringing near metal 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.

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

The magnetic field penetrates through water without any losses. Buoyancy helps in lifting finds.

1. Shear force

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

2. Steel thickness impact

*Thin steel (e.g. 0.5mm PC case) drastically limits 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) = 0.40

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.

Model MPL 50x25x12 / N38 features a low profile and industrial pulling force, making it an ideal solution for building separators and machines. As a magnetic bar with high power (approx. 37.12 kg), this product is available immediately from our warehouse in Poland. Furthermore, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, giving it an aesthetic appearance.

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 50x25x12 / 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 50x25x12 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. They work great as fasteners under tiles, wood, or glass. Customers often choose this model for workshop organization on strips and for advanced DIY and modeling projects, where precision and power count.

Cyanoacrylate glues (super glue type) are good only for small magnets; for larger plates, we recommend resins. 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.

Standardly, the MPL 50x25x12 / N38 model is magnetized axially (dimension 12 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 (50x25 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.

This model is characterized by dimensions 50x25x12 mm, which, at a weight of 112.5 g, makes it an element with impressive energy density. The key parameter here is the lifting capacity amounting to approximately 37.12 kg (force ~364.18 N), which, with such a flat shape, proves the high power of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages as well as disadvantages of Nd₂Fe₁₄B magnets.

Benefits

Besides their magnetic performance, neodymium magnets are valued for these benefits:

They have constant strength, and over around 10 years their attraction force decreases symbolically – ~1% (according to theory),
They have excellent resistance to magnetism drop due to external fields,
Thanks to the smooth finish, the surface of nickel, gold, or silver gives an elegant appearance,
Magnetic induction on the working layer of the magnet remains extremely intense,
Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling action at temperatures approaching 230°C and above...
Possibility of detailed creating and adapting to complex conditions,
Versatile presence in modern technologies – they are used in HDD drives, electromotive mechanisms, precision medical tools, as well as complex engineering applications.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which allows their use in small systems

Weaknesses

Problematic aspects of neodymium magnets and ways of using them

Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a steel housing, which not only protects them against impacts but also increases their durability
When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
We recommend casing - magnetic mount, due to difficulties in producing nuts inside the magnet and complicated shapes.
Potential hazard to health – tiny shards of magnets are risky, when accidentally swallowed, which becomes key in the context of child safety. Additionally, small components of these products are able to complicate diagnosis medical when they are in the body.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Pull force analysis

Detachment force of the magnet in optimal conditions – what affects it?

The specified lifting capacity refers to the peak performance, measured under laboratory conditions, namely:

with the use of a yoke made of low-carbon steel, ensuring maximum field concentration
whose transverse dimension reaches at least 10 mm
with an ideally smooth contact surface
under conditions of gap-free contact (surface-to-surface)
during detachment in a direction perpendicular to the mounting surface
in neutral thermal conditions

Lifting capacity in real conditions – factors

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

Distance – existence of any layer (paint, tape, gap) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
Substrate thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
Steel grade – ideal substrate is pure iron steel. Cast iron may have worse magnetic properties.
Base smoothness – the smoother and more polished the plate, the better the adhesion and stronger the hold. Roughness creates an air distance.
Temperature – temperature increase results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity was determined by applying a polished steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under parallel forces the load capacity is reduced by as much as fivefold. In addition, even a small distance between the magnet and the plate decreases the holding force.

Safe handling of NdFeB magnets

Handling rules

Handle magnets consciously. Their huge power can surprise even experienced users. Be vigilant and respect their force.

Warning for heart patients

Warning for patients: Strong magnetic fields affect electronics. Keep minimum 30 cm distance or ask another person to handle the magnets.

Allergic reactions

A percentage of the population experience a sensitization to Ni, which is the common plating for neodymium magnets. Extended handling might lead to dermatitis. We strongly advise wear safety gloves.

Maximum temperature

Watch the temperature. Exposing the magnet above 80 degrees Celsius will ruin its properties and strength.

Bodily injuries

Large magnets can crush fingers instantly. Under no circumstances place your hand betwixt two attracting surfaces.

Combustion hazard

Machining of neodymium magnets carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.

Electronic hazard

Very strong magnetic fields can destroy records on payment cards, HDDs, and other magnetic media. Keep a distance of min. 10 cm.

GPS Danger

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

Swallowing risk

These products are not intended for children. Eating a few magnets can lead to them pinching intestinal walls, which constitutes a critical condition and requires urgent medical intervention.

Magnets are brittle

Protect your eyes. Magnets can fracture upon violent connection, ejecting shards into the air. Eye protection is mandatory.
