Magnetic force drops drastically with every subsequent millimeter of spacing. Remember that every additional insulation layer (e.g., dirt, varnish, dust) strongly reduces the pull force. Magnetic products hold strongest at the point of direct contact; gap drastically cuts the power. See how rapidly the parameters fall, when the product does not touch tightly to the metal substrate. When calculating the mounting, discard redundant distances.

The table below indicates the theoretical force sufficient to start the sliding of the magnet vertically along a vertical metal surface (assuming standard friction). This parameter varies with the separation distance between the magnet and the surface.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces
MPL 25x12.5x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	2.32 kg / 5.11 LBS 2316.0 g / 22.7 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.54 kg / 3.40 LBS 1544.0 g / 15.1 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.77 kg / 1.70 LBS 772.0 g / 7.6 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	3.86 kg / 8.51 LBS 3860.0 g / 37.9 N

When mounting a magnet on a vertical surface (e.g., a car body), it will only hold just about 1/5 of its nominal power. Gravity and a low friction coefficient cause that magnets slip faster than they detach. Want to create a vertical fastening? Consider that the sliding force is noticeably lower than the perpendicular breakaway force. On a slippery surface, the holder will give way down under a much lighter weight. Application of an anti-slip coating can effectively raise the stability.

12 mm	100%	7.72 kg / 17.02 LBS 7720.0 g / 75.7 N

A thin sheet is not enough to take in the entire magnetic field, which squanders power of the holder. If you attach a powerful product to a weak sheet, the field will penetrate right through and the attraction force will be weaker. To squeeze full efficiency of this magnet's potential, you require a sufficiently solid backing of steel. The saturation phenomenon causes that on sheet metal structures (e.g., car bodies), the holder shows lower pull force. We recommend selecting the steel dimension according to the table below.

Classic neodymiums change their properties power after exceeding the maximum temperature. Watch out for overheating – excessive heat can irreversibly demagnetize this magnet. With increasing heat, the magnet's capacity temporarily decreases. Refrain from using this product close to ovens higher than its operating temperature limit. Ignoring the limit will cause permanent loss of magnetic properties.

*Technical advisory: Thermal stability is determined by both grade, and the Permeance Coefficient Pc. Flat magnets (low permeance coefficient) risk losing magnetic properties under lower heat stress compared to rod magnets. Warning indicator in the table indicates a risk of irreversible loss for this specific geometry.

Two strong neodymiums attract each other from a significantly greater distance than a neodymium and metal setup. Such a system of two magnets creates a more powerful interaction and a wider radius of operation. Planning to create a solid fastener? Utilize two neodymiums instead of one magnet and a steel. Exercise caution that when bringing together two magnets, the pinch force is massive. The repulsion force is slightly lower than the connection force, but still significant.
*Flux density for N-N configuration reaches ~0 Gs in the exact middle between the magnets (caused by magnetic field nullification).
Note: Figures apply to friction force of two same neodymium magnets (friction coefficient ~0.15 for Ni-Ni plating).

Table 7: Protective zones (electronics) - precautionary measures

A strong magnetic field poses a real danger to electronic devices as well as pacemakers. These neodymiums generate a field that disrupts operation of sensitive medical devices. Notice: the invisible magnetic field penetrates the body and housings. Exceptional care must be exercised by people with hearing aids and insulin pumps. Also at risk are: mechanical watches, remotes, membranes, and screens. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Table 8: Impact energy (kinetic energy) - collision effects
MPL 25x12.5x5 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	26.76 km/h (7.43 m/s)	0.32 J
30 mm	44.85 km/h (12.46 m/s)	0.91 J
50 mm	57.88 km/h (16.08 m/s)	1.51 J
100 mm	81.85 km/h (22.74 m/s)	3.03 J

Neodymium magnets are delicate – a strong collision with metal can result in shattering. Watch the impact speed – a neodymium left loose speeds with massive force. Striking energy can cause material chips or painful pinches to skin. Hold the magnet firmly during installation so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h ends with a crack of the neodymium. Wear safety glasses when playing 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.

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

1. Wall mount (shear)

*Caution: On a vertical wall, the magnet holds only a fraction of its max power.

2. Efficiency vs thickness

*Thin metal sheet (e.g. 0.5mm PC case) significantly weakens the holding force.

3. Heat tolerance

*For N38 material, 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) = 0.35

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.

541.20 ZŁ brutto / pcs

Model MPL 25x12.5x5 / N38 features a flat shape and industrial pulling force, making it an ideal solution for building separators and machines. As a magnetic bar with high power (approx. 7.72 kg), this product is available immediately from our warehouse in Poland. The durable anti-corrosion layer ensures a long lifespan in a dry environment, protecting the core from oxidation.

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 7.72 kg can pinch very hard and cause hematomas. Never use metal tools for prying, as the brittle NdFeB material may chip and damage your eyes.

They constitute a key element in the production of generators and material handling systems. Thanks to the flat surface and high force (approx. 7.72 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 25x12.5x5 / 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. 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 25x12.5x5 / N38 model is magnetized axially (dimension 5 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), 12.5 mm (width), and 5 mm (thickness). It is a magnetic block with dimensions 25x12.5x5 mm and a self-weight of 11.72 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.

Pros

Besides their durability, neodymium magnets are valued for these benefits:

Their power is durable, and after around ten years it decreases only by ~1% (according to research),
They do not lose their magnetic properties even under close interference source,
Thanks to the glossy finish, the layer of Ni-Cu-Ni, gold-plated, or silver gives an modern appearance,
Magnetic induction on the working layer of the magnet turns out to be very high,
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...
Thanks to modularity in constructing and the ability to customize to client solutions,
Fundamental importance in modern technologies – they are commonly used in computer drives, electric motors, medical devices, and multitasking production systems.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Weaknesses

Disadvantages of NdFeB magnets:

They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
Due to limitations in producing nuts and complex shapes in magnets, we recommend using cover - magnetic mechanism.
Potential hazard related to microscopic parts of magnets pose a threat, if swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small components of these devices are able to disrupt the diagnostic process medical when they are in the body.
With budget limitations the cost of neodymium magnets is a challenge,

Lifting parameters

Optimal lifting capacity of a neodymium magnet – what it depends on?

Holding force of 7.72 kg is a measurement result executed under specific, ideal conditions:

using a plate made of low-carbon steel, acting as a magnetic yoke
whose transverse dimension is min. 10 mm
characterized by lack of roughness
under conditions of gap-free contact (surface-to-surface)
for force acting at a right angle (in the magnet axis)
at temperature room level

Magnet lifting force in use – key factors

Holding efficiency is influenced by specific conditions, mainly (from most important):

Space between magnet and steel – every millimeter of distance (caused e.g. by varnish or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
Loading method – catalog parameter refers to pulling vertically. When applying parallel force, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
Base massiveness – insufficiently thick plate does not close the flux, causing part of the power to be lost into the air.
Steel type – low-carbon steel gives the best results. Alloy admixtures decrease magnetic properties and lifting capacity.
Surface finish – ideal contact is obtained only on polished steel. Rough texture create air cushions, weakening the magnet.
Operating temperature – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).

Lifting capacity testing was performed on a smooth plate of optimal thickness, under a perpendicular pulling force, however under shearing force the holding force is lower. Moreover, even a slight gap between the magnet’s surface and the plate reduces the holding force.

Precautions when working with neodymium magnets

Electronic devices

Do not bring magnets close to a wallet, laptop, or screen. The magnetic field can destroy these devices and erase data from cards.

Compass and GPS

Navigation devices and smartphones are highly susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can permanently damage the internal compass in your phone.

Caution required

Handle with care. Rare earth magnets act from a distance and connect with massive power, often faster than you can react.

Permanent damage

Regular neodymium magnets (grade N) undergo demagnetization when the temperature surpasses 80°C. Damage is permanent.

Beware of splinters

Neodymium magnets are sintered ceramics, meaning they are fragile like glass. Impact of two magnets will cause them breaking into shards.

Avoid contact if allergic

Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If skin irritation occurs, cease handling magnets and use protective gear.

Implant safety

Patients with a pacemaker have to keep an safe separation from magnets. The magnetic field can stop the operation of the life-saving device.

This is not a toy

Product intended for adults. Small elements can be swallowed, causing serious injuries. Keep out of reach of kids and pets.

Pinching danger

Large magnets can smash fingers in a fraction of a second. Never put your hand between two attracting surfaces.

Fire risk

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