Pulling power weakens sharply per each millimeter of gap. Remember that even a very thin break (e.g., contamination, varnish, veneer) strongly diminishes the holding power. Magnetic products operate most effectively at the point of direct contact; distance drastically cuts the force. Observe how rapidly the load capacity fall, when the magnet does not adhere directly to the metal substrate. When planning the arrangement, discard unnecessary gaps.

The table below shows the approximate weight limit sufficient to start the shifting of the magnet vertically on a vertical metal surface (assuming standard friction). This parameter is relative to the separation distance between the magnet and the surface.

Table 3: Vertical assembly (sliding) - 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

Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.95 kg / 2.08 LBS 945.0 g / 9.3 N

When placing a element on a upright plane (e.g., a board), it will maintain only about 20%-30% of nominal attraction strength. Gravity and a low friction coefficient influence the fact that magnets slide down easier than they pop off the substrate. Want to create a wall mount? Consider that the shear force is much weaker than the maximum static pull force. On a painted metal, the magnet will slide down under a much lighter weight. Application of an anti-slip coating can significantly increase the grip.

A thin sheet is unable to take in the entire magnetic field, which weakens actual performance of the magnet. Should you mount a strong magnet to a thin surface, the flux will pass right through and the attraction force will be weaker. To achieve the maximum of this neodymium's power, you require a sufficiently solid backing of metal. The saturation phenomenon means that on sheet metal structures (e.g., thin profiles), the holder holds weaker. We recommend selecting the steel dimension according to the table below.

Ordinary NdFeB products change their properties power above the temperature limit. Watch out for overheating – high temperature can irreversibly damage this magnet. With every degree above norm, the neodymium's capacity temporarily decreases. Refrain from using this magnet near heat sources exceeding its working range. Ignoring the limit will result in permanent loss of magnetism.

*Technical advisory: Temperature resistance is determined by both grade, but also on the magnet's shape. Flat magnets (low permeance coefficient) may lose charge permanently at lower temperatures than taller cylinders. Warning indicator in the table points to permanent field degradation for this specific geometry.

Two magnets attract each other from a wider radius than a magnet and sheet setup. The setup of magnet-to-magnet produces a massive flux and a further horizon of operation. Want to build a solid fastener? Use a pair of magnets instead of one magnet and a steel. Remember that when attracting two neodymiums, the collision energy is extreme. The repulsion force is marginally weaker than the connection force, but still impressive.
*Field value in repulsion mode drops to ~0 Gs at the midpoint of the gap (due to field cancellation).
Note: Results demonstrate sliding force of dual same magnets (friction coefficient ~0.15 for Ni-Ni plating).

A strong magnetic field is a large risk to electronics and pacemakers. These NdFeB products generate a field that destroys function of sensitive medical devices. Be aware: the unseen radiation passes through tissues and glass. Exceptional care must be taken by people with cochlear implants and drug dispensers. Also at risk are: mechanical watches, remotes, speakers, and displays. Avoid contact with magnetic cards, HDD media, or sensitive navigation tools.

Magnetic elements are very brittle – a strong collision with metal can result in shattering. Control the attraction moment – a magnet released freely speeds with massive force. Striking energy can cause material chips or painful pinches to skin. Hold the magnet firmly during bringing near metal so it doesn't slam with momentum against the steel surface. A collision at high speed almost guarantees destruction of the magnet. Wear eye protection when playing with powerful specimens.

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

Contrary to myths, water does not block the magnetic field. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Vertical hold

*Warning: On a vertical surface, the magnet retains just approx. 20-30% of its nominal pull.

2. Steel thickness impact

*Thin steel (e.g. 0.5mm PC case) drastically limits the holding force.

3. Heat tolerance

*For standard magnets, the critical limit is 80°C.

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

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

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 an extremely strong plate magnet made of NdFeB material, which, with dimensions of 25x15x2 mm and a weight of 5.63 g, guarantees premium class connection. This rectangular block with a force of 18.53 N is ready for shipment in 24h, allowing for rapid realization of your project. Additionally, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, giving it an aesthetic appearance.

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 extreme caution, because after separation, the magnets may want to violently snap back together, which threatens pinching the skin. Using a screwdriver risks destroying the coating and permanently cracking the magnet.

Plate magnets MPL 25x15x2 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. Thanks to the flat surface and high force (approx. 1.89 kg), they are ideal as closers in furniture making and mounting elements in automation. Customers often choose this model for hanging tools 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. For lighter applications or mounting on smooth surfaces, branded foam tape (e.g., 3M VHB) will work, provided the surface is perfectly degreased. 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. In practice, this means that this magnet has the greatest attraction force on its main planes (25x15 mm), which is ideal for flat mounting. This is the most popular configuration for block magnets used in separators and holders.

The presented product is a neodymium magnet with precisely defined parameters: 25 mm (length), 15 mm (width), and 2 mm (thickness). It is a magnetic block with dimensions 25x15x2 mm and a self-weight of 5.63 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Pros and cons of Nd₂Fe₁₄B magnets.

Strengths

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

They have constant strength, and over around ten years their attraction force decreases symbolically – ~1% (according to theory),
They do not lose their magnetic properties even under close interference source,
A magnet with a shiny silver surface has better aesthetics,
The surface of neodymium magnets generates a intense magnetic field – this is a key feature,
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 custom machining as well as modifying to atypical requirements,
Fundamental importance in advanced technology sectors – they are utilized in HDD drives, brushless drives, medical devices, also other advanced devices.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Weaknesses

What to avoid - cons of neodymium magnets: application proposals

To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
Magnets exposed to a humid environment can rust. Therefore while using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
Limited ability of producing threads in the magnet and complex forms - preferred is a housing - magnetic holder.
Potential hazard resulting from small fragments of magnets can be dangerous, if swallowed, which gains importance in the context of child health protection. Furthermore, small components of these magnets can disrupt the diagnostic process medical in case of swallowing.
Due to expensive raw materials, their price is relatively high,

Pull force analysis

Optimal lifting capacity of a neodymium magnet – what affects it?

The specified lifting capacity concerns the maximum value, obtained under ideal test conditions, specifically:

with the use of a yoke made of low-carbon steel, ensuring full magnetic saturation
possessing a massiveness of min. 10 mm to avoid saturation
characterized by lack of roughness
under conditions of no distance (surface-to-surface)
during detachment in a direction vertical to the mounting surface
at ambient temperature approx. 20 degrees Celsius

What influences lifting capacity in practice

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

Clearance – the presence of foreign body (rust, dirt, gap) acts as an insulator, which lowers capacity steeply (even by 50% at 0.5 mm).
Angle of force application – highest force is obtained only during perpendicular pulling. The resistance to sliding of the magnet along the plate is usually several times smaller (approx. 1/5 of the lifting capacity).
Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
Chemical composition of the base – mild steel gives the best results. Alloy admixtures decrease magnetic permeability and lifting capacity.
Smoothness – full contact is obtained only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
Temperature – temperature increase results in weakening of force. It is worth remembering the thermal limit for a given model.

Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under perpendicular forces, whereas under parallel forces the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate lowers the holding force.

Safety rules for work with neodymium magnets

Magnets are brittle

Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.

Pacemakers

For implant holders: Powerful magnets disrupt medical devices. Keep minimum 30 cm distance or request help to handle the magnets.

Heat warning

Do not overheat. NdFeB magnets are sensitive to heat. If you require resistance above 80°C, ask us about HT versions (H, SH, UH).

Crushing risk

Watch your fingers. Two large magnets will snap together instantly with a force of several hundred kilograms, destroying everything in their path. Be careful!

Dust is flammable

Powder created during grinding of magnets is combustible. Avoid drilling into magnets unless you are an expert.

Nickel coating and allergies

A percentage of the population experience a contact allergy to nickel, which is the standard coating for neodymium magnets. Frequent touching might lead to a rash. We recommend use protective gloves.

Do not give to children

Adult use only. Tiny parts pose a choking risk, causing severe trauma. Keep away from children and animals.

Safe operation

Use magnets consciously. Their immense force can surprise even experienced users. Plan your moves and do not underestimate their power.

Data carriers

Powerful magnetic fields can erase data on credit cards, hard drives, and other magnetic media. Maintain a gap of min. 10 cm.

GPS Danger

An intense magnetic field disrupts the operation of compasses in phones and GPS navigation. Do not bring magnets near a device to avoid breaking the sensors.
