Magnetic force drops sharply with every subsequent millimeter of spacing. Note that even the smallest break (e.g., dirt, varnish, veneer) strongly reduces the holding power. Neodymiums work most effectively at the point of contact; distance kills the power. See how rapidly the load capacity plummets when the product does not adhere directly to the steel. When designing the assembly, avoid redundant gaps.

Table 2: Vertical assembly (shearing) - behavior on slippery surfaces
MPL 60x20x10 / N38

Surface Type	Friction Coefficient / % Mocy	Max Load (kg)
Raw steel	µ = 0.3 30% Nominalnej Siły	6.03 kg / 6030.0 g 59.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	4.02 kg / 4020.0 g 39.4 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	2.01 kg / 2010.0 g 19.7 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	10.05 kg / 10050.0 g 98.6 N

When mounting a magnet on a upright plane (e.g., a fridge), it will only hold barely about 20%-30% of its maximum pull. Gravitational force as well as a low degree of grip mean that magnets slip faster than they pull off. Planning a hanger? Remember that the shear force is significantly lower than the perpendicular pull force. On a smooth surface, the magnet will slide down under a much smaller load. The application of an rubber pad can drastically increase the result.

Table 3: Steel thickness (substrate influence) - sheet metal selection
MPL 60x20x10 / N38

Steel Thickness (mm)	% Power	Real Pull (kg)
0.5 mm	5%	1.01 kg / 1005.0 g 9.9 N
1 mm	13%	2.51 kg / 2512.5 g 24.6 N
2 mm	25%	5.03 kg / 5025.0 g 49.3 N
5 mm	63%	12.56 kg / 12562.5 g 123.2 N
10 mm	100%	20.10 kg / 20100.0 g 197.2 N

A thin sheet cannot take in the full magnetic flux, which weakens the holder's power. Should you attach a strong magnet to weak sheet metal, the flux will penetrate right through and the holding will be lower. To utilize the maximum of this magnet's power, you require a sufficiently solid piece of steel. The saturation effect means that on delicate walls (e.g., car bodies), the holder works weaker. We suggest selecting the steel cross-section based on the following data.

Table 4: Working in heat (behavior) - thermal limit
MPL 60x20x10 / N38

Ambient Temp. (°C)	Power Loss	Remaining Pull	Status
20 °C	0.0%	20.10 kg / 20100.0 g 197.2 N	OK
40 °C	-2.2%	19.66 kg / 19657.8 g 192.8 N	OK
60 °C	-4.4%	19.22 kg / 19215.6 g 188.5 N	OK

100 °C	-28.8%	14.31 kg / 14311.2 g 140.4 N

Ordinary neodymiums lose their magnetic properties after exceeding the maximum temperature. Watch out for high temperatures – high temperature can permanently destroy this product. As the temperature rises, the neodymium's power briefly drops. Do not use this magnet near heat sources higher than its working range. Ignoring the limit will cause permanent degradation of magnetic properties.

Two strong magnets attract each other from a much further distance than a magnet and steel combination. A two-magnet connection creates a more powerful field and a larger radius of action. Want to create a strong closure? Use a pair of magnets instead of one magnet and a striker plate. Remember that when connecting a pair of magnets, the pinch force is massive. The repulsion force is slightly lower than the attraction, but still substantial.

Table 6: Safety (HSE) (implants) - warnings
MPL 60x20x10 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	16.5 cm

A powerful magnetic field is a real danger to electronics and medical implants. These magnets generate a flux that disrupts the operation of sensitive medical devices. Remember: the invisible radiation passes through bodies and plastic. Special caution must be exercised by people with hearing aids and drug dispensers. Risk also applies to: automatic timepieces, car keys, speakers, and displays. Do not place the magnet away from cards, hard drives, or precise measuring tools.

Table 7: Collisions (kinetic energy) - impact effects
MPL 60x20x10 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	15.97 km/h (4.44 m/s)	0.89 J
30 mm	26.19 km/h (7.27 m/s)	2.38 J
50 mm	33.71 km/h (9.36 m/s)	3.95 J
100 mm	47.66 km/h (13.24 m/s)	7.89 J

Neodymium magnets are fragile – a violent impact against metal risks shattering. Watch out for the impact speed – a magnet left loose turns into a projectile. Kinetic energy can trigger material chips or painful crushing of skin. Always hold the magnet during mounting so it doesn't hit the steel with momentum. A collision at a speed of dozens of km/h almost guarantees the destruction of the magnet. Wear protective goggles when working with powerful specimens.

Table 8: Coating parameters (durability)

This product is a very powerful magnet in the shape of a plate made of NdFeB material, which, with dimensions of 60x20x10 mm and a weight of 90 g, guarantees the highest quality connection. As a block magnet with high power (approx. 20.1 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 60x20x10 / 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.

They constitute a key element in the production of generators and material handling systems. Thanks to the flat surface and high force (approx. 20.1 kg), they are ideal as hidden locks 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. Avoid chemically aggressive glues or hot glue, which can demagnetize neodymium (above 80°C).

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 (60x20 mm), which is ideal for flat mounting. 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: 60 mm (length), 20 mm (width), and 10 mm (thickness). The key parameter here is the lifting capacity amounting to approximately 20.1 kg (force ~197.17 N), which, with such a compact shape, proves the high grade of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Pros as well as cons of neodymium magnets.

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

They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (according to literature),
They do not lose their magnetic properties even under close interference source,
The use of an elegant coating of noble metals (nickel, gold, silver) causes the element to have 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...
Thanks to the ability of free shaping and customization to unique projects, neodymium magnets can be modeled in a wide range of geometric configurations, which increases their versatility,
Wide application in innovative solutions – they are utilized in computer drives, drive modules, medical equipment, also complex engineering applications.
Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,

Characteristics of disadvantages of neodymium magnets and ways of using them

At strong impacts they can break, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
We suggest casing - magnetic holder, due to difficulties in producing threads inside the magnet and complicated forms.
Possible danger related to microscopic parts of magnets pose a threat, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Furthermore, small elements of these devices can complicate diagnosis medical after entering the body.
With mass production the cost of neodymium magnets is a challenge,

Maximum lifting force for a neodymium magnet – what contributes to it?

The load parameter shown refers to the maximum value, obtained under ideal test conditions, namely:

on a base made of structural steel, optimally conducting the magnetic flux
whose transverse dimension reaches at least 10 mm
with a surface perfectly flat
under conditions of ideal adhesion (metal-to-metal)
under perpendicular force direction (90-degree angle)
at ambient temperature room level

Lifting capacity in real conditions – factors

Real force impacted by working environment parameters, mainly (from priority):

Clearance – the presence of any layer (paint, dirt, gap) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
Loading method – catalog parameter refers to detachment vertically. When slipping, the magnet holds much less (typically approx. 20-30% of nominal force).
Plate thickness – too thin steel does not accept the full field, causing part of the flux to be wasted to the other side.
Plate material – mild steel gives the best results. Alloy steels decrease magnetic properties and lifting capacity.
Smoothness – full contact is obtained only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
Heat – NdFeB sinters have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).

* Lifting capacity was assessed with the use of a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, however under parallel forces the holding force is lower. Moreover, even a small distance {between} the magnet and the plate decreases the load capacity.

Safe handling of NdFeB magnets

Crushing force

Large magnets can smash fingers instantly. Never put your hand between two attracting surfaces.

Mechanical processing

Fire hazard: Rare earth powder is explosive. Do not process magnets in home conditions as this may cause fire.

GPS and phone interference

Remember: rare earth magnets generate a field that interferes with precision electronics. Keep a safe distance from your phone, tablet, and GPS.

Data carriers

Powerful magnetic fields can erase data on payment cards, hard drives, and other magnetic media. Stay away of at least 10 cm.

Heat warning

Avoid heat. NdFeB magnets are sensitive to heat. If you require resistance above 80°C, ask us about HT versions (H, SH, UH).

Life threat

People with a pacemaker have to keep an large gap from magnets. The magnetic field can interfere with the functioning of the implant.

Swallowing risk

Only for adults. Tiny parts can be swallowed, causing severe trauma. Keep away from children and animals.

Protective goggles

NdFeB magnets are ceramic materials, meaning they are fragile like glass. Clashing of two magnets leads to them breaking into shards.

Handling guide

Be careful. Rare earth magnets attract from a long distance and snap with massive power, often quicker than you can react.

Metal Allergy

It is widely known that nickel (the usual finish) is a common allergen. If your skin reacts to metals, refrain from touching magnets with bare hands or choose versions in plastic housing.
