Pulling power weakens drastically per each millimeter of distance. Note that even a microscopic distance (e.g., contamination, paint, dust) noticeably reduces the pull force. Neodymiums work strongest in perfect adhesion; distance nullifies the power. Notice how quickly the parameters fall, when the magnet does not adhere tightly to the steel surface. When calculating the mounting, avoid unnecessary gaps.

The following data presents the approximate holding capacity sufficient to cause the shifting of the magnet downwards along a vertical steel wall (assuming typical friction). This parameter depends on the gap size between the magnet and the metal.

Table 3: Vertical assembly (shearing) - vertical pull
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 mounting a magnet on a vertical surface (e.g., a board), it will only hold barely approx. 1/5 of its nominal power. Gravitational force and a weak degree of grip influence the fact that magnets slide down easier than they pull off. Want to create a vertical fastening? Consider that the sliding force is noticeably lower than the perpendicular breakaway force. On a painted metal, the magnet will slip down under a significantly smaller weight. Utilizing a rubberized coating can drastically increase the grip.

12 mm	100%	1.89 kg / 4.17 lbs 1890.0 g / 18.5 N

A thin sheet cannot focus the full magnetic flux, which squanders power of the magnet. If you install a neodymium to a too thin substrate, the field will pass right through and the attraction force will be weaker. To achieve the maximum of this neodymium's power, you need a suitably thick element of steel. The saturation phenomenon means that on sheet metal structures (e.g., appliance housings), the magnet holds weaker. We advise picking the steel cross-section from these parameters.

Ordinary NdFeB products change their properties strength above the temperature limit. Watch out for overheating – high temperature can irreversibly destroy this magnet. With increasing heat, the magnet's force briefly drops. Refrain from using this magnet near heat sources exceeding its working range. Exceeding the critical threshold will lead to irreversible degradation of magnetic properties.

*Important note: Temperature resistance is determined by both grade, and the Permeance Coefficient Pc. Thin magnets (low permeance coefficient) risk losing magnetic properties under lower heat stress than taller cylinders. Red status in the table signals permanent field degradation for this specific geometry.

Two magnetic products interact from a wider radius than a magnet and steel setup. The setup of two magnets generates a stronger field and a further horizon of operation. Want to build a solid fastener? Utilize two neodymiums instead of a neodymium and a steel. Remember that when connecting a pair of magnets, the pinch force is huge. The levitation is a bit weaker than the attraction, but still large.
*Flux density in repulsion mode reaches ~0 Gs at the geometric center between the magnets (due to field cancellation).
Note: Estimates show shear force of a pair of matching magnets (friction coefficient ~0.15 for Ni-Ni layer).

Extremely neodym field is a serious hazard to IT equipment as well as pacemakers. These neodymiums produce a field that disrupts operation of digital equipment. Remember: the unseen radiation penetrates the body and glass. Increased vigilance must be exercised by people with hearing aids and insulin pumps. Also at risk are: automatic timepieces, car keys, speakers, and displays. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

Table 8: Collisions (kinetic energy) - warning

NdFeB products are very brittle – a violent impact against metal causes immediate chipping. Watch the impact speed – a magnet released freely turns into a projectile. Impact energy can trigger coating fragments or injury to fingers. Hold the magnet firmly during mounting so it doesn't hit with great force against the steel surface. A contact at a velocity of dozens of km/h ends with a crack of the magnet. Wear safety glasses when handling with powerful specimens.

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

Contrary to myths, water does not block the magnetic field. However, remember the water resistance when pulling the rope quickly.

1. Sliding resistance

*Warning: On a vertical surface, the magnet holds merely a fraction of its nominal pull.

2. Steel saturation

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

3. Thermal stability

*For N38 grade, the safety limit is 80°C.

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

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

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 plate magnet made of NdFeB material, which, with dimensions of 25x15x2 mm and a weight of 5.63 g, guarantees premium class connection. This magnetic 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 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. Watch your fingers! Magnets with a force of 1.89 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 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.

For mounting flat magnets MPL 25x15x2 / N38, we recommend utilizing 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 clean and degrease the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

The magnetic axis runs through the shortest dimension, which is typical for gripper magnets. 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 product meets the standards for N38 grade magnets.

Advantages and disadvantages of Nd₂Fe₁₄B magnets.

Advantages

Apart from their strong magnetic energy, neodymium magnets have these key benefits:

Their magnetic field is maintained, and after approximately ten years it drops only by ~1% (according to research),
Neodymium magnets are distinguished by highly resistant to demagnetization caused by external magnetic fields,
A magnet with a shiny silver surface has an effective appearance,
The surface of neodymium magnets generates a powerful magnetic field – this is one of their assets,
Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling functioning at temperatures approaching 230°C and above...
Considering the possibility of accurate molding and customization to specialized requirements, magnetic components can be modeled in a wide range of forms and dimensions, which expands the range of possible applications,
Fundamental importance in future technologies – they are used in computer drives, drive modules, medical devices, as well as modern systems.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which allows their use in miniature devices

Disadvantages

Problematic aspects of neodymium magnets and proposals for their use:

At very strong impacts they can break, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
NdFeB magnets lose power 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 very resistant to heat
They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
Limited ability of creating nuts in the magnet and complicated forms - preferred is a housing - magnet mounting.
Possible danger resulting from small fragments of magnets pose a threat, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Additionally, small elements of these devices are able to complicate diagnosis medical in case of swallowing.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities

Lifting parameters

Maximum magnetic pulling force – what contributes to it?

The load parameter shown concerns the maximum value, measured under ideal test conditions, meaning:

with the contact of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
possessing a thickness of min. 10 mm to avoid saturation
characterized by even structure
under conditions of no distance (metal-to-metal)
for force applied at a right angle (pull-off, not shear)
at temperature room level

What influences lifting capacity in practice

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

Gap between surfaces – every millimeter of distance (caused e.g. by varnish or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
Load vector – highest force is obtained only during pulling at a 90° angle. The shear force of the magnet along the surface is standardly several times lower (approx. 1/5 of the lifting capacity).
Substrate thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
Steel type – mild steel gives the best results. Alloy admixtures decrease magnetic properties and holding force.
Smoothness – ideal contact is obtained only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
Temperature – heating the magnet causes a temporary drop of force. It is worth remembering the thermal limit for a given model.

Lifting capacity was measured using a polished steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under shearing force the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet and the plate lowers the load capacity.

Safety rules for work with NdFeB magnets

Do not overheat magnets

Standard neodymium magnets (N-type) lose magnetization when the temperature exceeds 80°C. This process is irreversible.

Keep away from electronics

Remember: neodymium magnets generate a field that disrupts sensitive sensors. Maintain a safe distance from your phone, tablet, and GPS.

Avoid contact if allergic

Studies show that the nickel plating (standard magnet coating) is a strong allergen. If you have an allergy, avoid direct skin contact and select coated magnets.

Electronic devices

Do not bring magnets near a wallet, computer, or screen. The magnetic field can permanently damage these devices and erase data from cards.

ICD Warning

Individuals with a heart stimulator have to keep an safe separation from magnets. The magnetic field can interfere with the operation of the implant.

Bodily injuries

Watch your fingers. Two large magnets will join immediately with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!

Mechanical processing

Fire hazard: Neodymium dust is highly flammable. Avoid machining magnets in home conditions as this risks ignition.

Protective goggles

Neodymium magnets are ceramic materials, which means they are fragile like glass. Clashing of two magnets will cause them cracking into shards.

Handling guide

Handle with care. Neodymium magnets act from a long distance and connect with huge force, often faster than you can move away.

This is not a toy

These products are not intended for children. Eating multiple magnets may result in them connecting inside the digestive tract, which constitutes a critical condition and requires immediate surgery.
