Magnetic force decreases sharply per each millimeter of distance. Remember that every additional insulation layer (e.g., dirt, paint, rust) noticeably weakens the grip. Neodymiums work optimally in perfect adhesion; gap weakens the force. Observe how flashily the pull force drop, when the magnet does not adhere directly to the steel surface. When planning the arrangement, avoid additional spacers.

The table below calculates the estimated force necessary to cause the downward movement of the magnet downwards on a upright steel wall (assuming standard friction coefficient). This value is relative to the gap size between the magnet and the surface.

Table 3: Vertical assembly (sliding) - vertical pull
MPL 12.5x12.5x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	1.45 kg / 3.20 LBS 1452.0 g / 14.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.97 kg / 2.13 LBS 968.0 g / 9.5 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.48 kg / 1.07 LBS 484.0 g / 4.7 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	2.42 kg / 5.34 LBS 2420.0 g / 23.7 N

When hanging a holder on a upright surface (e.g., a fridge), it you can count on just about 20%-30% of its maximum pull force. Gravity and a weak degree of grip mean that holders move down faster than they detach. Want to create a wall mount? Remember that the sliding force is noticeably lower than the maximum static pull force. On a painted metal, the holder will slip down under a much lighter load. Utilizing a rubberized layer can significantly raise the stability.

12 mm	100%	4.84 kg / 10.67 LBS 4840.0 g / 47.5 N

A too thin steel cannot take in the full magnetic flux, which weakens actual performance of the holder. Should you mount a strong magnet to a weak sheet, the field will pass right through and the attraction force will be weaker. To squeeze 100% of this neodymium's power, you need a suitably thick piece of metal. The saturation phenomenon means that on thin elements (e.g., appliance housings), the holder holds weaker. We suggest choosing the steel cross-section based on the following data.

Ordinary NdFeB products irreversibly lose power after exceeding the maximum temperature. Protect against heat – high temperature can irreversibly destroy this product. As the temperature rises, the neodymium's capacity briefly lowers. Refrain from using this magnet close to heaters exceeding its safe range. Exceeding the critical threshold will lead to destruction of magnetic properties.

*Technical advisory: Heat tolerance depends not only on the material grade, as well as the dimension ratios. Low-profile magnets (low Pc) are more susceptible to demagnetization under lower heat stress compared to rod magnets. Red status in the table signals permanent field degradation for this particular item.

Two magnetic products interact from a much further distance than a magnet and steel setup. The setup of two magnets produces a massive flux and a wider radius of action. Planning to create a solid fastener? Utilize two neodymiums instead of one magnet and a striker plate. Remember that when connecting a pair of magnets, the pinch force is huge. The levitation is a bit weaker than the attraction, but still significant.
*Flux density for N-N configuration reaches ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
* Estimates apply to sliding force of dual matching magnets (friction ~0.15 for Ni-Ni layer).

Extremely neodym field poses a serious hazard to electronics and pacemakers. These magnets generate a field that destroys function of digital equipment. Notice: the invisible magnetic field passes through tissues and plastic. Special caution must be taken by people with cochlear implants and drug dispensers. The risk also applies to: automatic timepieces, remotes, speakers, and displays. Do not place the magnet near cards, HDD media, or precise measuring instruments.

Table 8: Impact energy (cracking risk) - collision effects

Neodymium magnets are very brittle – a strong collision with metal can result in shattering. Pay attention to connection velocity – a neodymium left loose speeds with massive force. Kinetic force can trigger coating fragments or injury to skin. Hold the magnet firmly during bringing near metal so it doesn't hit violently against the steel surface. A contact at a velocity of dozens of km/h means shattering of the neodymium. Wear eye protection when playing with powerful specimens.

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

In water, the magnet feels stronger thanks to Archimedes' principle. Buoyancy helps in lifting finds.

1. Wall mount (shear)

*Caution: On a vertical wall, the magnet retains merely approx. 20-30% of its max power.

2. Efficiency vs thickness

*Thin steel (e.g. 0.5mm PC case) significantly reduces the holding force.

3. Temperature resistance

*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) = 0.46

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 12.5x12.5x5 mm and a weight of 5.86 g, guarantees premium class connection. As a magnetic bar with high power (approx. 4.84 kg), this product is available off-the-shelf from our warehouse in Poland. Additionally, its Ni-Cu-Ni coating secures 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. To separate the MPL 12.5x12.5x5 / 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. 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 wind generators and material handling systems. They work great as invisible mounts 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 12.5x12.5x5 / N38, it is best to use two-component adhesives (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 roughen and wash 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 (12.5x12.5 mm), which is ideal for flat mounting. This is the most popular configuration for block magnets used in separators and holders.

This model is characterized by dimensions 12.5x12.5x5 mm, which, at a weight of 5.86 g, makes it an element with impressive energy density. The key parameter here is the holding force amounting to approximately 4.84 kg (force ~47.51 N), which, with such a compact shape, proves the high grade of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages as well as disadvantages of neodymium magnets.

Strengths

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

They virtually do not lose power, because even after 10 years the performance loss is only ~1% (in laboratory conditions),
They have excellent resistance to weakening of magnetic properties due to opposing magnetic fields,
Thanks to the shimmering finish, the layer of Ni-Cu-Ni, gold-plated, or silver gives an aesthetic appearance,
Neodymium magnets achieve maximum magnetic induction on a small area, which ensures high operational effectiveness,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
Thanks to versatility in constructing and the capacity to modify to complex applications,
Key role in electronics industry – they find application in magnetic memories, motor assemblies, advanced medical instruments, also other advanced devices.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in small systems

Disadvantages

Disadvantages of NdFeB magnets:

At very strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape as well as 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. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
We suggest cover - magnetic holder, due to difficulties in realizing nuts inside the magnet and complex shapes.
Possible danger related to microscopic parts of magnets are risky, if swallowed, which is particularly important in the context of child health protection. Additionally, small elements of these devices can disrupt the diagnostic process medical after entering the body.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Lifting parameters

Maximum magnetic pulling force – what affects it?

Holding force of 4.84 kg is a theoretical maximum value executed under the following configuration:

using a sheet made of high-permeability steel, serving as a magnetic yoke
possessing a massiveness of minimum 10 mm to ensure full flux closure
characterized by even structure
under conditions of ideal adhesion (metal-to-metal)
for force acting at a right angle (in the magnet axis)
at temperature approx. 20 degrees Celsius

Practical aspects of lifting capacity – factors

Real force is influenced by working environment parameters, such as (from most important):

Distance (betwixt the magnet and the metal), because even a microscopic distance (e.g. 0.5 mm) leads to a decrease in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
Angle of force application – maximum parameter is reached 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).
Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
Chemical composition of the base – mild steel gives the best results. Higher carbon content lower magnetic properties and lifting capacity.
Surface finish – full contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
Temperature – temperature increase causes a temporary drop of induction. Check the maximum operating temperature for a given model.

Lifting capacity was assessed by applying a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, whereas under parallel forces the lifting capacity is smaller. In addition, even a minimal clearance between the magnet’s surface and the plate lowers the holding force.

Warnings

Protect data

Very strong magnetic fields can destroy records on payment cards, hard drives, and other magnetic media. Stay away of min. 10 cm.

Beware of splinters

Beware of splinters. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. We recommend safety glasses.

GPS Danger

GPS units and smartphones are highly susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can permanently damage the sensors in your phone.

Danger to pacemakers

Individuals with a ICD have to maintain an safe separation from magnets. The magnetic field can interfere with the functioning of the life-saving device.

Machining danger

Dust produced during machining of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.

No play value

Only for adults. Tiny parts can be swallowed, leading to severe trauma. Store away from children and animals.

Crushing risk

Large magnets can break fingers in a fraction of a second. Do not put your hand betwixt two attracting surfaces.

Conscious usage

Be careful. Neodymium magnets attract from a distance and connect with huge force, often faster than you can move away.

Allergy Warning

Some people experience a hypersensitivity to nickel, which is the typical protective layer for NdFeB magnets. Prolonged contact may cause skin redness. We suggest wear safety gloves.

Heat sensitivity

Do not overheat. NdFeB magnets are sensitive to heat. If you require operation above 80°C, ask us about special high-temperature series (H, SH, UH).
