Pulling power drops drastically with every mm of distance. Remember that even the smallest gap (e.g., contamination, paint, rust) strongly diminishes the holding power. Neodymiums operate strongest in perfect adhesion; distance kills the force. Notice how quickly the parameters fall, when the product does not adhere directly to the steel surface. When designing the arrangement, avoid unnecessary gaps.

This section shows the approximate weight limit needed to cause the downward movement of the magnet vertically on a vertical steel wall (considering typical friction). This value depends on the air gap between the magnet and the metal.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
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 LBS 168.0 g / 1.6 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.11 kg / 0.25 LBS 112.0 g / 1.1 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.06 kg / 0.12 LBS 56.0 g / 0.5 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.28 kg / 0.62 LBS 280.0 g / 2.7 N

When placing a holder on a vertical surface (e.g., a car body), it you can count on only approx. 20%-30% of its nominal power. Gravity as well as a low friction coefficient mean that holders slip easier than they pull off. Planning a wall mount? Note that the shear force is significantly lower than the perpendicular breakaway force. On a smooth steel, the holder will slip down under a much lighter load. Using a rubber coating can drastically improve the result.

12 mm	100%	0.56 kg / 1.23 LBS 560.0 g / 5.5 N

A too thin steel is incapable of take in the entire magnetic field, which squanders power of the magnet. If you attach a powerful product to a too thin substrate, the flux will penetrate right through and the holding will be smaller. To achieve the maximum of this neodymium's power, you need a suitably thick backing of metal. The saturation effect causes that on thin elements (e.g., car bodies), the magnet shows lower pull force. We suggest choosing the steel cross-section from these parameters.

Standard neodymium magnets change their properties parameters after exceeding the maximum temperature. Protect against heat – heat can permanently destroy this product. With every degree above norm, the neodymium's force momentarily drops. Do not use this product close to ovens exceeding its working range. Exceeding the critical threshold will result in permanent loss of magnetic properties.

*Technical advisory: Heat tolerance is determined by both grade, as well as the dimension ratios. Low-profile magnets (low Pc) risk losing magnetic properties at lower temperatures compared to rod magnets. The danger warning in the table signals a risk of irreversible loss for this specific geometry.

Two magnetic products interact from a significantly greater distance than a neodymium and metal setup. The connection of magnet-to-magnet generates a stronger field and a further horizon of action. Designing a powerful holder? Apply two magnets instead of one magnet and a striker plate. Remember that when bringing together two magnets, the pinch force is massive. The repulsion force is marginally weaker than the attraction, but still large.
*Flux density between like poles is approximately ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
Note: Figures show sliding force of dual same magnets (friction ~0.15 for Ni-Ni layer).

Table 7: Hazards (implants) - warnings
MPL 20x10x1 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	4.5 cm

Powerful magnet radiation poses a serious hazard to electronic devices as well as pacemakers. These neodymiums generate a flux that disrupts operation of sensitive medical devices. Notice: the unseen radiation acts through matter and plastic. Increased vigilance must be exercised by people with hearing aids and insulin pumps. The risk also applies to: mechanical watches, remotes, membranes, and screens. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

Table 8: Collisions (kinetic energy) - collision effects
MPL 20x10x1 / N38

Start from (mm)	Speed (km/h)	Energy (J)

50 mm	43.57 km/h (12.10 m/s)	0.11 J
100 mm	61.62 km/h (17.12 m/s)	0.22 J

NdFeB products are very brittle – a strong collision with metal causes immediate chipping. Pay attention to connection velocity – a neodymium left loose becomes dangerous. Striking energy can destroy the magnet or injury to skin. Hold the magnet firmly during bringing near metal so it doesn't hit violently against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Wear safety glasses when handling with powerful specimens.

Corrosion warning: 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. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Sliding resistance

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

2. Efficiency vs thickness

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

3. Heat tolerance

*For standard magnets, 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) = 0.10

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.

This product is a very powerful plate magnet made of NdFeB material, which, with dimensions of 20x10x1 mm and a weight of 1.5 g, guarantees the highest quality connection. This magnetic block with a force of 5.46 N is ready for shipment in 24h, allowing for rapid realization of your project. The durable anti-corrosion layer ensures a long lifespan in a dry environment, protecting the core from oxidation.

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. Watch your fingers! Magnets with a force of 0.56 kg can pinch very hard and cause hematomas. 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. 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. 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. 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: 20 mm (length), 10 mm (width), and 1 mm (thickness). The key parameter here is the lifting capacity amounting to approximately 0.56 kg (force ~5.46 N), which, with such a compact shape, proves the high power of the material. The product meets the standards for N38 grade magnets.

Pros as well as cons of Nd₂Fe₁₄B magnets.

Pros

Apart from their superior magnetism, neodymium magnets have these key benefits:

Their strength is durable, and after around ten years it decreases only by ~1% (according to research),
Neodymium magnets are highly resistant to demagnetization caused by external field sources,
Thanks to the shimmering finish, the layer of nickel, gold-plated, or silver gives an elegant appearance,
The surface of neodymium magnets generates a unique magnetic field – this is a distinguishing feature,
Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
Thanks to the potential of precise shaping and adaptation to unique requirements, magnetic components can be created in a wide range of shapes and sizes, which expands the range of possible applications,
Fundamental importance in modern industrial fields – they are utilized in HDD drives, electromotive mechanisms, diagnostic systems, also industrial machines.
Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which allows their use in compact constructions

Cons

Disadvantages of NdFeB magnets:

Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a special holder, which not only secures them against impacts but also raises their durability
Neodymium magnets decrease their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
Limited ability of making threads in the magnet and complicated forms - recommended is casing - mounting mechanism.
Health risk resulting from small fragments of magnets are risky, in case of ingestion, which gains importance in the context of child safety. Furthermore, tiny parts of these magnets can complicate diagnosis medical after entering the body.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities

Holding force characteristics

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

Information about lifting capacity was determined for the most favorable conditions, assuming:

with the application of a sheet made of low-carbon steel, ensuring maximum field concentration
with a thickness no less than 10 mm
with an ideally smooth contact surface
with direct contact (without coatings)
under vertical force direction (90-degree angle)
in temp. approx. 20°C

Determinants of lifting force in real conditions

It is worth knowing that the working load may be lower depending on elements below, starting with the most relevant:

Distance – existence of any layer (paint, tape, gap) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
Load vector – maximum parameter is obtained only during pulling at a 90° angle. The shear force of the magnet along the plate is usually several times smaller (approx. 1/5 of the lifting capacity).
Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
Material type – the best choice is high-permeability steel. Hardened steels may generate lower lifting capacity.
Surface condition – smooth surfaces guarantee perfect abutment, which increases field saturation. Rough surfaces reduce efficiency.
Heat – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).

Lifting capacity was measured with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, however under attempts to slide the magnet the load capacity is reduced by as much as 75%. Moreover, even a small distance between the magnet and the plate reduces the load capacity.

H&S for magnets

Compass and GPS

An intense magnetic field disrupts the functioning of compasses in smartphones and GPS navigation. Keep magnets close to a device to prevent breaking the sensors.

Thermal limits

Control the heat. Heating the magnet above 80 degrees Celsius will permanently weaken its properties and strength.

Finger safety

Large magnets can crush fingers instantly. Never place your hand betwixt two strong magnets.

Handling rules

Be careful. Neodymium magnets act from a long distance and snap with huge force, often quicker than you can react.

Electronic devices

Powerful magnetic fields can destroy records on credit cards, HDDs, and other magnetic media. Maintain a gap of min. 10 cm.

Nickel allergy

It is widely known that nickel (the usual finish) is a common allergen. If your skin reacts to metals, avoid touching magnets with bare hands and opt for coated magnets.

Keep away from children

Adult use only. Small elements pose a choking risk, leading to serious injuries. Keep out of reach of kids and pets.

Medical implants

Medical warning: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.

Mechanical processing

Powder created during cutting of magnets is self-igniting. Do not drill into magnets unless you are an expert.

Magnet fragility

Despite the nickel coating, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
