Pulling power decreases drastically per each millimeter of distance. Keep in mind that even the smallest gap (e.g., contamination, varnish, veneer) significantly diminishes the holding power. Magnetic products operate strongest in perfect adhesion; distance weakens the force. Notice how quickly the pull force fall, when the magnet does not touch directly to the metal substrate. When planning the mounting, avoid additional spacers.

This section presents the approximate holding capacity sufficient to initiate the slippage of the magnet downwards against a upright steel wall (considering standard friction). This parameter varies with the air gap between the magnet and the surface.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces
MPL 25x15x2 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.57 kg / 1.25 lbs 567.0 g / 5.6 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.38 kg / 0.83 lbs 378.0 g / 3.7 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.19 kg / 0.42 lbs 189.0 g / 1.9 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.95 kg / 2.08 lbs 945.0 g / 9.3 N

When hanging a element on a vertical wall (e.g., a car body), it you can count on barely about 1/5 of its nominal power. Gravitational force and a weak degree of grip influence the fact that products slide down faster than they pop off the substrate. Planning a wall mount? Remember that the shear force is noticeably lower than the maximum static pull force. On a slippery surface, the magnet will slide down under a noticeably lighter weight. Application of an anti-slip layer can effectively increase the grip.

A thin sheet cannot absorb the full magnetic flux, which wastes potential of the holder. Should you attach a powerful product to a thin surface, the magnetism will pass right through and the attraction force will be weaker. To achieve full efficiency of this magnet's power, you require a sufficiently solid element of steel. The saturation phenomenon causes that on delicate walls (e.g., appliance housings), the magnet holds weaker. We recommend selecting the steel thickness from these parameters.

Standard neodymium magnets change their properties strength after exceeding the maximum temperature. Protect against heat – excessive heat can permanently demagnetize this magnet. With increasing heat, the neodymium's force temporarily drops. Refrain from using this product close to ovens higher than its working range. Too high temperature will result in permanent loss of magnetic properties.

*Important note: Thermal stability is determined by both grade, and the Permeance Coefficient Pc. Flat magnets (low permeance coefficient) may lose charge permanently at lower temperatures than long magnets. The danger warning in the table signals permanent field degradation for this particular item.

Two magnetic products attract each other from a wider radius than a magnet and sheet combination. The connection of magnet-to-magnet creates a more powerful interaction and a larger range of action. Planning to create a solid fastener? Utilize two neodymiums instead of a neodymium and a steel. Remember that when attracting two neodymiums, the pinch force is huge. The levitation is marginally weaker than the connection force, but still large.
*The magnetic induction between like poles reaches ~0 Gs at the midpoint between the magnets (resulting from vector opposition).
Important: Estimates refer to sliding force of dual matching neodymium magnets (friction ~0.15 for Ni-Ni layer).

Table 7: Safety (HSE) (electronics) - warnings

Extremely neodym field is a large risk to IT equipment as well as pacemakers. These NdFeB products produce a field that prevents correct functioning of digital equipment. Remember: the unseen radiation passes through tissues and glass. Special caution must be taken by people with hearing aids and drug dispensers. Also at risk are: mechanical watches, remotes, speakers, and displays. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Table 8: Dynamics (kinetic energy) - collision effects
MPL 25x15x2 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	19.58 km/h (5.44 m/s)	0.08 J

50 mm	41.32 km/h (11.48 m/s)	0.37 J
100 mm	58.43 km/h (16.23 m/s)	0.74 J

NdFeB products are delicate – a violent impact against metal risks their cracking. Watch the impact speed – a magnet released freely speeds with massive force. Striking energy can trigger coating fragments or injury to fingers. Hold the magnet firmly during bringing near metal so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Wear eye protection when handling with large magnets.

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

Water displaces steel, making heavy objects slightly lighter. 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 surface, the magnet holds only approx. 20-30% of its max power.

2. Steel saturation

*Thin steel (e.g. computer case) severely reduces the holding force.

3. Power loss vs temp

*For N38 grade, the max working temp is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.14

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 magnet in the shape of a plate made of NdFeB material, which, with dimensions of 25x15x2 mm and a weight of 5.63 g, guarantees the highest quality connection. As a block magnet with high power (approx. 1.89 kg), this product is available off-the-shelf from our warehouse in Poland. The durable anti-corrosion layer ensures a long lifespan in a dry environment, protecting the core from oxidation.

Separating block magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. To separate the MPL 25x15x2 / N38 model, firmly slide one magnet over the edge of the other until the attraction force decreases. We recommend care, 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 25x15x2 / N38 are the foundation for many industrial devices, such as filters catching filings and linear motors. Thanks to the flat surface and high force (approx. 1.89 kg), they are ideal as hidden locks in furniture making and mounting elements in automation. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.

For mounting flat magnets MPL 25x15x2 / N38, it is best to use 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 roughen and wash the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

Standardly, the MPL 25x15x2 / N38 model is magnetized axially (dimension 2 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.

The presented product is a neodymium magnet with precisely defined parameters: 25 mm (length), 15 mm (width), and 2 mm (thickness). The key parameter here is the holding force amounting to approximately 1.89 kg (force ~18.56 N), which, with such a compact shape, proves the high grade of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Strengths and weaknesses of Nd₂Fe₁₄B magnets.

Benefits

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

They retain full power for nearly 10 years – the loss is just ~1% (based on simulations),
They possess excellent resistance to weakening of magnetic properties when exposed to external magnetic sources,
The use of an elegant layer of noble metals (nickel, gold, silver) causes the element to present itself better,
Magnets are distinguished by exceptionally strong magnetic induction on the working surface,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
Possibility of precise modeling and optimizing to specific needs,
Fundamental importance in modern technologies – they are commonly used in hard drives, motor assemblies, diagnostic systems, and industrial machines.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in compact constructions

Cons

What to avoid - cons of neodymium magnets: weaknesses and usage proposals

Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a special holder, which not only secures them against impacts but also raises their durability
When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their power 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
Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
We recommend casing - magnetic mechanism, due to difficulties in producing nuts inside the magnet and complex shapes.
Possible danger to health – tiny shards of magnets can be dangerous, if swallowed, which becomes key in the context of child safety. Additionally, small components of these devices are able to be problematic in diagnostics medical after entering the body.
Due to complex production process, their price is higher than average,

Pull force analysis

Maximum magnetic pulling force – what it depends on?

The declared magnet strength refers to the limit force, recorded under ideal test conditions, namely:

using a base made of high-permeability steel, acting as a magnetic yoke
whose transverse dimension equals approx. 10 mm
with an ideally smooth contact surface
without the slightest clearance between the magnet and steel
for force applied at a right angle (pull-off, not shear)
at room temperature

Determinants of practical lifting force of a magnet

In real-world applications, the actual holding force depends on a number of factors, listed from the most important:

Clearance – the presence of foreign body (paint, dirt, gap) acts as an insulator, which lowers 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 significantly, often to levels of 20-30% of the nominal value.
Base massiveness – insufficiently thick sheet does not close the flux, causing part of the power to be wasted to the other side.
Chemical composition of the base – low-carbon steel gives the best results. Alloy admixtures decrease magnetic properties and lifting capacity.
Plate texture – ground elements ensure maximum contact, which increases field saturation. Rough surfaces weaken the grip.
Operating temperature – NdFeB sinters have a negative temperature coefficient. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).

Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Additionally, even a slight gap between the magnet and the plate lowers the holding force.

Safety rules for work with neodymium magnets

Magnets are brittle

Protect your eyes. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. We recommend safety glasses.

Fire warning

Machining of NdFeB material poses a fire risk. Neodymium dust reacts violently with oxygen and is hard to extinguish.

Serious injuries

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

Warning for heart patients

Patients with a heart stimulator have to maintain an large gap from magnets. The magnetism can interfere with the functioning of the life-saving device.

No play value

Always store magnets away from children. Risk of swallowing is significant, and the effects of magnets clamping inside the body are tragic.

Impact on smartphones

Remember: neodymium magnets produce a field that disrupts precision electronics. Keep a safe distance from your phone, tablet, and navigation systems.

Safe operation

Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.

Operating temperature

Control the heat. Exposing the magnet to high heat will ruin its magnetic structure and strength.

Protect data

Intense magnetic fields can erase data on credit cards, HDDs, and other magnetic media. Keep a distance of at least 10 cm.

Allergic reactions

Allergy Notice: The nickel-copper-nickel coating consists of nickel. If skin irritation happens, immediately stop working with magnets and use protective gear.
