Pulling power decreases sharply with every mm of distance. Note that even a microscopic distance (e.g., contamination, varnish, veneer) noticeably diminishes the holding power. Magnetic products operate most effectively during direct contact; air break nullifies the force. Analyze how flashily the load capacity plummet, when the product does not touch directly to the steel surface. When planning the mounting, discard unnecessary gaps.

The table below indicates the theoretical weight limit required to cause the slippage of the magnet vertically on a upright steel plate (assuming standard friction). This value is relative to the separation distance between the magnet and the surface.

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 plane (e.g., a board), it you can count on barely about 20%-30% of its nominal power. Gravitational force and a low friction coefficient cause that holders slip easier than they pull off. Designing a wall mount? Consider that the shear force is significantly lower than the perpendicular breakaway force. On a painted metal, the element will slip down under a much lighter load. Utilizing a rubberized layer can significantly improve the result.

A thin metal plate is not enough to focus the full magnetic flux, which squanders power of the magnet. Should you install a neodymium to a weak sheet, the flux will pass right through and the attraction force will be weaker. To utilize full efficiency of this neodymium's power, you require a sufficiently solid piece of metal. The saturation effect means that on sheet metal structures (e.g., appliance housings), the magnet works worse. We recommend selecting the steel dimension according to the table below.

Classic neodymiums change their properties parameters above the temperature limit. Watch out for overheating – high temperature can irreversibly destroy this product. With increasing heat, the neodymium's capacity temporarily decreases. Do not use this product close to heaters higher than its safe range. Exceeding the critical threshold will lead to permanent loss of magnetic properties.

*Important note: Thermal stability is determined by both grade, as well as the dimension ratios. Low-profile magnets (pancake types) risk losing magnetic properties sooner compared to rod magnets. Red status in the table points to a risk of irreversible loss for this particular item.

Two magnets interact from a significantly greater distance than a magnet and sheet setup. Such a system of magnet-to-magnet creates a more powerful interaction and a larger range of action. Want to build a solid fastener? Utilize two neodymiums instead of a neodymium and a steel. Remember that when bringing together two magnets, the collision energy is extreme. The repulsion force is slightly lower than the attraction, but still impressive.
*The magnetic induction between like poles is approximately ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
Note: Results refer to friction force of dual identical magnets (friction coefficient ~0.15 for Ni-Ni layer).

A strong magnetic field is a large risk to electronics as well as medical implants. These neodymiums generate a field that disrupts operation of digital equipment. Be aware: the invisible magnetic field penetrates the body and housings. Special caution must be taken by people with cochlear implants and insulin pumps. Also at risk are: automatic timepieces, remotes, membranes, and screens. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

Neodymium magnets are very brittle – a violent impact against metal can result in shattering. Pay attention to connection velocity – a neodymium left loose turns into a projectile. Kinetic force can cause material chips or dangerous crushing to fingers. Always hold the magnet during installation so it doesn't hit violently against the steel surface. A contact at a velocity of dozens of km/h ends with a crack of the magnet. Wear safety glasses when working with powerful specimens.

Corrosion warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

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

1. Shear force

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

2. Steel saturation

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

3. Power loss vs temp

*For N38 grade, 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 flat shape and industrial pulling force, making it an ideal 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. The durable anti-corrosion layer ensures a long lifespan in a dry environment, protecting the core from oxidation.

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 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. 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. Thanks to the flat surface and high force (approx. 0.56 kg), they are ideal as closers 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.

For mounting flat magnets MPL 20x10x1 / 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. Avoid chemically aggressive glues or hot glue, which can demagnetize neodymium (above 80°C).

Standardly, the MPL 20x10x1 / N38 model is magnetized through the thickness (dimension 1 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. This is the most popular configuration for block magnets used in separators and holders.

This model is characterized by dimensions 20x10x1 mm, which, at a weight of 1.5 g, makes it an element with high energy density. The key parameter here is the lifting capacity amounting to approximately 0.56 kg (force ~5.46 N), which, with such a flat shape, proves the high power of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages as well as disadvantages of Nd₂Fe₁₄B magnets.

Pros

In addition to their pulling strength, neodymium magnets provide the following advantages:

They virtually do not lose strength, because even after ten years the decline in efficiency is only ~1% (based on calculations),
Neodymium magnets are characterized by remarkably resistant to loss of magnetic properties caused by magnetic disturbances,
A magnet with a metallic nickel surface is more attractive,
They are known for high magnetic induction at the operating surface, making them more effective,
Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
Possibility of individual shaping and optimizing to individual applications,
Universal use in future technologies – they find application in mass storage devices, electric motors, medical equipment, as well as technologically advanced constructions.
Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Cons

Cons of neodymium magnets: tips and applications.

To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
We suggest a housing - magnetic mechanism, due to difficulties in producing threads inside the magnet and complex forms.
Possible danger resulting from small fragments of magnets are risky, in case of ingestion, which gains importance in the aspect of protecting the youngest. Additionally, tiny parts of these devices can be problematic in diagnostics medical in case of swallowing.
With budget limitations the cost of neodymium magnets can be a barrier,

Pull force analysis

Maximum lifting force for a neodymium magnet – what affects it?

Holding force of 0.56 kg is a result of laboratory testing conducted under specific, ideal conditions:

using a base made of high-permeability steel, serving as a circuit closing element
possessing a massiveness of min. 10 mm to avoid saturation
with a plane cleaned and smooth
without the slightest air gap between the magnet and steel
for force acting at a right angle (pull-off, not shear)
at temperature room level

Impact of factors on magnetic holding capacity in practice

Bear in mind that the working load may be lower subject to elements below, starting with the most relevant:

Space between surfaces – every millimeter of distance (caused e.g. by varnish or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
Base massiveness – too thin steel causes magnetic saturation, causing part of the power to be wasted into the air.
Steel grade – the best choice is high-permeability steel. Hardened steels may have worse magnetic properties.
Surface structure – the more even the surface, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
Heat – NdFeB sinters have a sensitivity to temperature. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).

Lifting capacity was measured using a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, however under parallel forces the holding force is lower. Moreover, even a slight gap between the magnet’s surface and the plate decreases the holding force.

Safety rules for work with NdFeB magnets

Cards and drives

Do not bring magnets near a purse, computer, or screen. The magnetism can permanently damage these devices and erase data from cards.

Fire warning

Mechanical processing of NdFeB material carries a risk of fire risk. Magnetic powder reacts violently with oxygen and is hard to extinguish.

Conscious usage

Before use, read the rules. Sudden snapping can break the magnet or hurt your hand. Think ahead.

Material brittleness

Watch out for shards. Magnets can fracture upon violent connection, launching sharp fragments into the air. We recommend safety glasses.

Serious injuries

Mind your fingers. Two large magnets will snap together instantly with a force of massive weight, crushing anything in their path. Exercise extreme caution!

Warning for allergy sufferers

A percentage of the population experience a sensitization to Ni, which is the typical protective layer for NdFeB magnets. Extended handling can result in skin redness. We strongly advise wear protective gloves.

Choking Hazard

NdFeB magnets are not intended for children. Eating multiple magnets may result in them attracting across intestines, which poses a severe health hazard and requires urgent medical intervention.

Phone sensors

A powerful magnetic field disrupts the operation of compasses in phones and navigation systems. Maintain magnets close to a smartphone to avoid breaking the sensors.

Operating temperature

Do not overheat. NdFeB magnets are sensitive to heat. If you need resistance above 80°C, look for HT versions (H, SH, UH).

Health Danger

For implant holders: Strong magnetic fields disrupt electronics. Maintain minimum 30 cm distance or ask another person to handle the magnets.
