Pulling power drops significantly per each millimeter of distance. Keep in mind that even a very thin break (e.g., dirt, varnish, dust) significantly diminishes the holding power. Magnets work optimally in perfect adhesion; distance nullifies the power. See how flashily the pull force fall, when the product does not touch flatly to the steel surface. When planning the arrangement, eliminate unnecessary gaps.

The following data presents the estimated holding capacity required to cause the shifting of the magnet down on a upright metal surface (considering standard friction coefficient). The holding force is a function of the gap size between the magnet and the metal.

Table 3: Vertical assembly (sliding) - vertical pull
MPL 25x2x6 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.70 kg / 1.54 lbs 699.0 g / 6.9 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.47 kg / 1.03 lbs 466.0 g / 4.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.23 kg / 0.51 lbs 233.0 g / 2.3 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.17 kg / 2.57 lbs 1165.0 g / 11.4 N

When hanging a holder on a upright plane (e.g., a board), it you can count on only approx. 1/5 of its maximum pull force. Gravity and a weak degree of grip mean that holders move down easier than they detach. Want to create a vertical fastening? Consider that the shear force is noticeably lower than the perpendicular breakaway force. On a slippery surface, the element will slip down under a noticeably lighter cargo. Application of an anti-slip layer can significantly improve the result.

12 mm	100%	2.33 kg / 5.14 lbs 2330.0 g / 22.9 N

A thin metal plate is not enough to take in the full magnetic flux, which squanders power of the holder. Should you attach a powerful product to a thin surface, the field will penetrate right through and the holding will be smaller. To achieve 100% of this magnet's potential, you need a suitably thick element of metal. The saturation phenomenon causes that on delicate walls (e.g., appliance housings), the holder shows lower pull force. We recommend selecting the steel cross-section from these parameters.

Classic neodymiums change their properties parameters above the temperature limit. Watch out for overheating – excessive heat can permanently destroy this product. With every degree above norm, the magnet's power briefly decreases. Refrain from using this product near heat sources exceeding its working range. Ignoring the limit will lead to irreversible degradation of magnetism.

*Technical advisory: Thermal stability is determined by both grade, but also on the magnet's shape. Low-profile magnets (low Pc) are more susceptible to demagnetization sooner than taller cylinders. Red status in the table points to permanent field degradation for this particular item.

Two magnets attract each other from a wider radius than a magnet and sheet combination. The connection of two magnets creates a more powerful interaction and a further horizon of performance. Want to build a strong closure? Use a pair of magnets instead of one magnet and a steel. Exercise caution that when connecting a pair of magnets, the impact force is huge. The repulsion force is marginally weaker than the attraction, but still large.
*Flux density for N-N configuration reaches ~0 Gs in the exact middle between the magnets (caused by magnetic field nullification).
Attention: Calculations demonstrate sliding force of dual matching magnets (friction coefficient ~0.15 for Ni-Ni layer).

Extremely neodym field is a large risk to IT equipment and medical implants. These magnets produce a flux that disrupts operation of sensitive medical devices. Remember: the invisible magnetic field penetrates the body and glass. Increased vigilance must be exercised by people with hearing aids and drug dispensers. The risk also applies to: automatic timepieces, remotes, speakers, and displays. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Table 8: Impact energy (cracking risk) - warning
MPL 25x2x6 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	32.47 km/h (9.02 m/s)	0.09 J
30 mm	56.21 km/h (15.61 m/s)	0.27 J
50 mm	72.57 km/h (20.16 m/s)	0.46 J
100 mm	102.63 km/h (28.51 m/s)	0.91 J

Neodymium magnets are very brittle – a collision with steel risks their cracking. Control the attraction moment – a magnet released freely speeds with massive force. Impact energy can destroy the magnet or painful pinches to skin. Always hold the magnet during bringing near metal so it doesn't slam with momentum against the metal. A contact at a velocity of dozens of km/h means shattering of the neodymium. Wear eye protection when handling with powerful specimens.

Rust risk: 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. Buoyancy helps in lifting finds.

1. Shear force

*Warning: On a vertical surface, the magnet holds only ~20% of its max power.

2. Plate thickness effect

*Thin steel (e.g. computer case) significantly weakens 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) = 0.76

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.

Model MPL 25x2x6 / N38 features a flat shape and industrial pulling force, making it a perfect solution for building separators and machines. This magnetic block with a force of 22.82 N is ready for shipment in 24h, allowing for rapid realization of your project. 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. Watch your fingers! Magnets with a force of 2.33 kg can pinch very hard and cause hematomas. Using a screwdriver risks destroying the coating and permanently cracking the magnet.

They constitute a key element in the production of wind generators and material handling systems. They work great as invisible mounts under tiles, wood, or glass. 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 25x2x6 / 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. Avoid chemically aggressive glues or hot glue, which can demagnetize neodymium (above 80°C).

Standardly, the MPL 25x2x6 / N38 model is magnetized axially (dimension 6 mm), which means that the N and S poles are located on its largest, flat surfaces. 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.

This model is characterized by dimensions 25x2x6 mm, which, at a weight of 2.25 g, makes it an element with high energy density. It is a magnetic block with dimensions 25x2x6 mm and a self-weight of 2.25 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages and disadvantages of rare earth magnets.

Benefits

In addition to their magnetic capacity, neodymium magnets provide the following advantages:

They retain full power for almost 10 years – the loss is just ~1% (in theory),
Neodymium magnets prove to be highly resistant to magnetic field loss caused by external field sources,
A magnet with a smooth gold surface looks better,
Neodymium magnets generate maximum magnetic induction on a small area, which ensures high operational effectiveness,
Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
In view of the possibility of flexible shaping and customization to unique needs, neodymium magnets can be manufactured in a wide range of shapes and sizes, which makes them more universal,
Versatile presence in innovative solutions – they are utilized in magnetic memories, electric drive systems, advanced medical instruments, as well as multitasking production systems.
Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,

Disadvantages

Disadvantages of neodymium magnets:

To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
We recommend cover - magnetic holder, 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 aspect of protecting the youngest. It is also worth noting that small elements of these magnets are able to be problematic in diagnostics medical in case of swallowing.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Pull force analysis

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

Magnet power was determined for ideal contact conditions, assuming:

on a base made of mild steel, perfectly concentrating the magnetic field
with a thickness no less than 10 mm
characterized by even structure
under conditions of ideal adhesion (surface-to-surface)
under axial application of breakaway force (90-degree angle)
at conditions approx. 20°C

What influences lifting capacity in practice

Please note that the magnet holding will differ depending on the following factors, in order of importance:

Clearance – existence of any layer (rust, tape, air) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
Load vector – highest force is available only during perpendicular pulling. The shear force of the magnet along the surface is typically several times lower (approx. 1/5 of the lifting capacity).
Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
Material type – ideal substrate is high-permeability steel. Stainless steels may attract less.
Surface quality – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
Temperature – temperature increase causes a temporary drop of induction. Check the maximum operating temperature for a given model.

Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under shearing force the lifting capacity is smaller. Additionally, even a slight gap between the magnet and the plate lowers the lifting capacity.

Warnings

Pacemakers

Medical warning: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.

This is not a toy

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

Combustion hazard

Mechanical processing of neodymium magnets poses a fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.

Sensitization to coating

Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If redness occurs, immediately stop working with magnets and wear gloves.

Magnetic media

Do not bring magnets near a wallet, computer, or TV. The magnetic field can irreversibly ruin these devices and erase data from cards.

Handling guide

Handle magnets consciously. Their immense force can shock even professionals. Be vigilant and do not underestimate their power.

Threat to navigation

A strong magnetic field disrupts the operation of compasses in smartphones and navigation systems. Keep magnets near a smartphone to prevent damaging the sensors.

Finger safety

Pinching hazard: The pulling power is so immense that it can result in hematomas, pinching, and broken bones. Use thick gloves.

Fragile material

Watch out for shards. Magnets can explode upon uncontrolled impact, launching shards into the air. We recommend safety glasses.

Permanent damage

Control the heat. Heating the magnet to high heat will ruin its properties and pulling force.
