Grip strength decreases significantly with every subsequent millimeter of spacing. Note that even a microscopic distance (e.g., contamination, paint, veneer) strongly diminishes the holding power. Magnetic products hold strongest in perfect adhesion; gap drastically cuts the power. Notice how flashily the parameters drop, when the magnet does not adhere flatly to the steel surface. When designing the assembly, avoid additional spacers.

This section presents the estimated holding capacity sufficient to start the slippage of the magnet down along a vertical steel plate (assuming standard friction coefficient). This value is relative to the distance between the magnet and the surface.

Table 3: Vertical assembly (shearing) - vertical pull
MPL 20x10x1 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.17 kg / 0.37 pounds 168.0 g / 1.6 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.11 kg / 0.25 pounds 112.0 g / 1.1 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.06 kg / 0.12 pounds 56.0 g / 0.5 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.28 kg / 0.62 pounds 280.0 g / 2.7 N

When hanging a holder on a upright wall (e.g., a car body), it will maintain barely approx. 20%-30% of its maximum pull force. Gravity and a weak degree of grip cause that holders slip easier than they pop off the substrate. Want to create a hanger? Remember that the sliding force is significantly lower than the maximum static pull force. On a slippery surface, the element will give way down under a much lighter cargo. Utilizing a rubberized pad can significantly increase the grip.

A thin sheet cannot take in the entire magnetic field, which weakens actual performance of the magnet. If you attach a powerful product to a too thin substrate, the field will penetrate right through and the holding will be smaller. To utilize 100% of this neodymium's potential, you need a suitably thick element of steel. The material oversaturation causes that on delicate walls (e.g., thin profiles), the holder holds weaker. We suggest choosing the steel thickness according to the table below.

Classic neodymiums change their properties strength after exceeding the maximum temperature. Protect against heat – high temperature can irreversibly damage this magnet. As the temperature rises, the magnet's power briefly decreases. Avoid using this magnet in hot environments exceeding its working range. Too high temperature will cause irreversible degradation of magnetism.

*Important note: Thermal stability is determined by both grade, and the Permeance Coefficient Pc. Flat magnets (low permeance coefficient) may lose charge permanently sooner than taller cylinders. Red status in the table points to permanent field degradation for this specific geometry.

Two magnets attract each other from a much further distance than a magnet and steel setup. Such a system of two magnets produces a massive flux and a larger range of operation. Planning to create a solid fastener? Use a pair of magnets instead of a neodymium and a steel. Remember that when attracting two neodymiums, the pinch force is massive. The levitation is slightly lower than the attraction, but still impressive.
*Flux density in repulsion mode is approximately ~0 Gs at the midpoint of the gap (resulting from vector opposition).
Attention: Results demonstrate shear force of two identical neodymium magnets (friction ~0.15 for Ni-Ni plating).

Extremely neodym field is a real danger to electronics and pacemakers. These neodymiums produce a flux that prevents correct functioning of digital equipment. Be aware: the unseen radiation penetrates the body and glass. Special caution must be taken by people with cochlear implants and drug dispensers. Influence will be felt by: automatic timepieces, remotes, speakers, and displays. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Neodymium magnets are delicate – a collision with steel can result in shattering. Watch the impact speed – a neodymium left loose speeds with massive force. Striking energy can destroy the magnet or injury to skin. Be sure to control the product during mounting 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. Use safety goggles when working with powerful specimens.

Corrosion warning: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

The magnetic field penetrates through water without any losses. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Shear force

*Caution: On a vertical wall, the magnet holds merely approx. 20-30% of its nominal pull.

2. Steel thickness impact

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

3. Power loss vs temp

*For N38 material, the critical limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.10

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.

Model MPL 20x10x1 / N38 features a low profile and industrial pulling force, making it a perfect solution for building separators and machines. This rectangular block with a force of 5.46 N is ready for shipment in 24h, allowing for rapid realization of your project. Furthermore, its Ni-Cu-Ni coating protects it against corrosion in standard operating conditions, giving it an aesthetic appearance.

The key to success is shifting the magnets along their largest connection plane (using e.g., the edge of a table), which is easier than trying to tear them apart directly. To separate the MPL 20x10x1 / 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.

Plate magnets MPL 20x10x1 / N38 are the foundation for many industrial devices, such as filters catching filings and linear motors. Thanks to the flat surface and high force (approx. 0.56 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.

Cyanoacrylate glues (super glue type) are good only for small magnets; for larger plates, we recommend resins. 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 20x10x1 / N38 model is magnetized axially (dimension 1 mm), which means that the N and S poles are located on its largest, flat surfaces. In practice, this means that this magnet has the greatest attraction force on its main planes (20x10 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.

This model is characterized by dimensions 20x10x1 mm, which, at a weight of 1.5 g, makes it an element with impressive energy density. It is a magnetic block with dimensions 20x10x1 mm and a self-weight of 1.5 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Strengths and weaknesses of neodymium magnets.

Benefits

In addition to their long-term stability, neodymium magnets provide the following advantages:

They have constant strength, and over nearly ten years their attraction force decreases symbolically – ~1% (according to theory),
They feature excellent resistance to magnetic field loss due to opposing magnetic fields,
In other words, due to the shiny finish of silver, the element becomes visually attractive,
Magnets have impressive magnetic induction on the outer side,
Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures approaching 230°C and above...
Thanks to flexibility in shaping and the ability to modify to specific needs,
Universal use in modern technologies – they are used in HDD drives, motor assemblies, precision medical tools, and other advanced devices.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which allows their use in miniature devices

Weaknesses

Disadvantages of neodymium magnets:

They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
Neodymium magnets decrease their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
Limited possibility of making threads in the magnet and complicated forms - preferred is cover - magnetic holder.
Health risk resulting from small fragments of magnets can be dangerous, in case of ingestion, which becomes key in the context of child health protection. Furthermore, small components of these magnets can complicate diagnosis medical when they are in the body.
Due to neodymium price, their price exceeds standard values,

Lifting parameters

Maximum holding power of the magnet – what affects it?

The lifting capacity listed is a theoretical maximum value conducted under specific, ideal conditions:

with the application of a sheet made of special test steel, guaranteeing full magnetic saturation
whose thickness equals approx. 10 mm
characterized by smoothness
with zero gap (no impurities)
under axial force vector (90-degree angle)
at ambient temperature approx. 20 degrees Celsius

Lifting capacity in practice – influencing factors

In real-world applications, the real power results from several key aspects, presented from most significant:

Space between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
Force direction – catalog parameter refers to detachment vertically. When attempting to slide, the magnet holds much less (typically approx. 20-30% of nominal force).
Metal thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
Steel type – mild steel gives the best results. Higher carbon content lower magnetic permeability and holding force.
Surface condition – ground elements ensure maximum contact, which increases field saturation. Uneven metal weaken the grip.
Thermal factor – hot environment weakens magnetic field. Too high temperature can permanently demagnetize the magnet.

Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Additionally, even a small distance between the magnet’s surface and the plate reduces the load capacity.

Warnings

Maximum temperature

Control the heat. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and strength.

Keep away from computers

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

Do not drill into magnets

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

Pacemakers

Patients with a heart stimulator have to keep an absolute distance from magnets. The magnetic field can stop the operation of the implant.

Avoid contact if allergic

Some people experience a sensitization to Ni, which is the common plating for NdFeB magnets. Frequent touching can result in skin redness. We recommend wear safety gloves.

Conscious usage

Handle magnets consciously. Their immense force can surprise even professionals. Stay alert and respect their power.

GPS and phone interference

Remember: neodymium magnets produce a field that interferes with sensitive sensors. Maintain a separation from your mobile, device, and GPS.

Protective goggles

NdFeB magnets are ceramic materials, which means they are prone to chipping. Collision of two magnets leads to them cracking into shards.

Bodily injuries

Watch your fingers. Two powerful magnets will join immediately with a force of massive weight, crushing everything in their path. Exercise extreme caution!

Do not give to children

Neodymium magnets are not toys. Eating multiple magnets can lead to them attracting across intestines, which constitutes a critical condition and requires immediate surgery.

Attention! Learn more about hazards in the article: Magnet Safety Guide.
