Magnetic force decreases sharply with every mm of spacing. Note that even a microscopic distance (e.g., contamination, paint, dust) noticeably weakens the grip. Magnets hold optimally during direct contact; gap drastically cuts the force. Notice how flashily the parameters drop, when the product does not touch directly to the steel surface. When calculating the assembly, avoid redundant distances.

The table below defines the theoretical force necessary to initiate the sliding of the magnet downwards on a vertical steel plate (assuming standard friction coefficient). This value is relative to the gap size between the magnet and the surface.

Table 3: Vertical assembly (shearing) - vertical pull
MPL 40x10x4 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	2.79 kg / 6.16 lbs 2793.0 g / 27.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.86 kg / 4.11 lbs 1862.0 g / 18.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.93 kg / 2.05 lbs 931.0 g / 9.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	4.66 kg / 10.26 lbs 4655.0 g / 45.7 N

When mounting a magnet on a upright surface (e.g., a car body), it will maintain just about 20%-30% of its nominal power. Gravitational force and a low friction coefficient mean that holders move down easier than they detach. Planning a wall mount? Note that the shear force is much weaker than the perpendicular breakaway force. On a slippery surface, the magnet will slide down under a significantly smaller weight. Utilizing a rubberized coating can drastically improve the result.

12 mm	100%	9.31 kg / 20.53 lbs 9310.0 g / 91.3 N

A thin metal plate cannot focus the entire magnetic field, which wastes potential of the holder. If you install a neodymium to a too thin substrate, the magnetism will pass right through and the pull force will drop sharply. To utilize full efficiency of this neodymium's potential, you need a suitably thick element of steel. The material oversaturation causes that on thin elements (e.g., car bodies), the magnet holds weaker. We suggest choosing the steel dimension from these parameters.

Standard neodymium magnets change their properties parameters above the temperature limit. Avoid high temperatures – excessive heat can irreversibly destroy this product. As the temperature rises, the neodymium's force briefly drops. Refrain from using this magnet close to ovens exceeding its safe range. Exceeding the critical threshold will lead to irreversible degradation of magnetic properties.

*Important note: Heat tolerance is determined by both grade, and the Permeance Coefficient Pc. Flat magnets (pancake types) risk losing magnetic properties under lower heat stress than long magnets. Warning indicator in the table signals permanent field degradation for this particular item.

Two strong neodymiums interact from a significantly greater distance than a neodymium and metal combination. The setup of two magnets produces a massive flux and a wider radius of operation. Planning to create a powerful holder? Utilize two neodymiums instead of a neodymium and a steel. Remember that when connecting a pair of magnets, the pinch force is massive. The levitation is marginally weaker than the connection force, but still significant.
*The magnetic induction between like poles is approximately ~0 Gs in the exact middle between the magnets (due to field cancellation).
Important: Estimates refer to friction force of dual same neodymium magnets (friction ~0.15 for Ni-Ni plating).

Table 7: Safety (HSE) (implants) - precautionary measures
MPL 40x10x4 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	8.5 cm

A strong magnetic field poses a serious hazard to electronics and pacemakers. These neodymiums produce a field that prevents correct functioning of sensitive medical devices. Remember: the invisible magnetic field penetrates the body and plastic. Increased vigilance must be taken by people with hearing aids and insulin pumps. Influence will be felt by: mechanical watches, car keys, speakers, and displays. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Table 8: Collisions (cracking risk) - warning
MPL 40x10x4 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	28.72 km/h (7.98 m/s)	0.38 J
30 mm	48.67 km/h (13.52 m/s)	1.10 J
50 mm	62.82 km/h (17.45 m/s)	1.83 J
100 mm	88.83 km/h (24.68 m/s)	3.65 J

NdFeB products are very brittle – a collision with steel risks their cracking. Watch the impact speed – a magnet released freely becomes dangerous. Kinetic force can cause material chips or painful pinches to fingers. 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 almost guarantees destruction of the neodymium. Use safety goggles when working 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!

Water displaces steel, making heavy objects slightly lighter. However, remember the water resistance when pulling the rope quickly.

1. Wall mount (shear)

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

2. Efficiency vs thickness

*Thin steel (e.g. 0.5mm PC case) severely weakens the holding force.

3. Heat tolerance

*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) = 0.26

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.

Component MPL 40x10x4 / N38 features a low profile and professional pulling force, making it a perfect solution for building separators and machines. As a block magnet with high power (approx. 9.31 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 block magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. To separate the MPL 40x10x4 / 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 40x10x4 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. Thanks to the flat surface and high force (approx. 9.31 kg), they are ideal as closers 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 40x10x4 / N38, we recommend utilizing two-component adhesives (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.

Standardly, the MPL 40x10x4 / N38 model is magnetized axially (dimension 4 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.

This model is characterized by dimensions 40x10x4 mm, which, at a weight of 12 g, makes it an element with impressive energy density. It is a magnetic block with dimensions 40x10x4 mm and a self-weight of 12 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages and disadvantages of Nd₂Fe₁₄B magnets.

Pros

Besides their tremendous magnetic power, neodymium magnets offer the following advantages:

They do not lose magnetism, even during nearly ten years – the decrease in strength is only ~1% (theoretically),
They possess excellent resistance to weakening of magnetic properties due to opposing magnetic fields,
Thanks to the shiny finish, the layer of Ni-Cu-Ni, gold-plated, or silver gives an elegant appearance,
Magnetic induction on the top side of the magnet remains very high,
Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
Possibility of exact shaping and modifying to concrete needs,
Universal use in high-tech industry – they are used in mass storage devices, brushless drives, medical equipment, as well as multitasking production systems.
Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,

Disadvantages

Disadvantages of neodymium magnets:

At strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
Neodymium magnets lose strength 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 extremely resistant to heat
When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
We suggest a housing - magnetic mount, due to difficulties in realizing threads inside the magnet and complicated forms.
Potential hazard to health – tiny shards of magnets are risky, when accidentally swallowed, which gains importance in the context of child safety. Furthermore, small components of these devices can complicate diagnosis medical in case of swallowing.
Due to expensive raw materials, their price is higher than average,

Holding force characteristics

Detachment force of the magnet in optimal conditions – what it depends on?

The specified lifting capacity represents the peak performance, obtained under laboratory conditions, namely:

with the use of a yoke made of special test steel, ensuring full magnetic saturation
possessing a thickness of min. 10 mm to avoid saturation
with a plane free of scratches
without the slightest air gap between the magnet and steel
for force applied at a right angle (pull-off, not shear)
at conditions approx. 20°C

Practical lifting capacity: influencing factors

It is worth knowing that the magnet holding may be lower depending on elements below, in order of importance:

Gap between surfaces – even a fraction of a millimeter of separation (caused e.g. by veneer or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
Element thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
Plate material – mild steel gives the best results. Higher carbon content lower magnetic properties and holding force.
Surface structure – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
Thermal factor – high temperature weakens magnetic field. Too high temperature can permanently damage the magnet.

Lifting capacity was measured with the use of a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, however under parallel forces the load capacity is reduced by as much as 75%. In addition, even a slight gap between the magnet’s surface and the plate lowers the lifting capacity.

Warnings

Fragile material

NdFeB magnets are sintered ceramics, meaning they are prone to chipping. Collision of two magnets will cause them breaking into shards.

Magnetic media

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

Demagnetization risk

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

Sensitization to coating

Medical facts indicate that the nickel plating (the usual finish) is a strong allergen. If your skin reacts to metals, avoid direct skin contact or choose coated magnets.

Precision electronics

Note: neodymium magnets generate a field that interferes with precision electronics. Maintain a safe distance from your mobile, device, and GPS.

Machining danger

Fire hazard: Neodymium dust is highly flammable. Do not process magnets in home conditions as this may cause fire.

Implant safety

Life threat: Neodymium magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.

Hand protection

Large magnets can break fingers in a fraction of a second. Under no circumstances put your hand betwixt two attracting surfaces.

Danger to the youngest

Only for adults. Tiny parts can be swallowed, leading to serious injuries. Keep away from children and animals.

Powerful field

Be careful. Rare earth magnets act from a long distance and connect with massive power, often quicker than you can move away.
