Magnetic force weakens drastically with every subsequent millimeter of spacing. Remember that even the smallest gap (e.g., dirt, varnish, dust) significantly weakens the grip. Magnetic products hold optimally during direct contact; distance nullifies the force. See how rapidly the parameters fall, when the magnet does not touch tightly to the metal substrate. When calculating the arrangement, eliminate redundant distances.

The following data defines the theoretical weight limit needed to cause the downward movement of the magnet down on a vertical metal surface (assuming standard friction). This parameter is a function of the distance between the magnet and the surface.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces

Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.11 kg / 0.25 lbs 112.0 g / 1.1 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 mounting a element on a vertical plane (e.g., a fridge), it will maintain barely about 20%-30% of its maximum pull force. Gravity and a weak degree of grip influence the fact that holders move down faster than they detach. Designing a wall mount? Note that the shear force is noticeably lower than the perpendicular breakaway force. On a slippery surface, the magnet will slip down under a significantly smaller load. Using a rubber pad can drastically raise the stability.

A thin sheet is not enough to conduct the entire magnetic field, which weakens actual performance of the holder. Should you mount a strong magnet to a weak sheet, the magnetism will penetrate right through and the attraction force will be weaker. To squeeze the maximum of this magnet's power, you require a sufficiently solid element of steel. The saturation phenomenon means that on delicate walls (e.g., thin profiles), the magnet works worse. We recommend selecting the steel thickness from these parameters.

Standard neodymium magnets lose power above the temperature limit. Watch out for overheating – excessive heat can irreversibly destroy this product. With every degree above norm, the magnet's power briefly lowers. Do not use this magnet near heat sources exceeding its operating temperature limit. Exceeding the critical threshold will result in destruction of magnetic properties.

*Engineering note: Temperature resistance is determined by both grade, but also on the magnet's shape. Low-profile magnets (low Pc) may lose charge permanently at lower temperatures compared to rod magnets. The danger warning in the table signals a risk of irreversible loss for this specific geometry.

Two magnets attract each other from a wider radius than a magnet and steel combination. The connection of two magnets creates a more powerful interaction and a larger range of action. Planning to create a strong closure? Use a pair of magnets instead of a neodymium and a steel. Remember that when attracting two neodymiums, the collision energy is huge. The levitation is marginally weaker than the connection force, but still significant.
*The magnetic induction between like poles reaches ~0 Gs in the exact middle of the gap (caused by magnetic field nullification).
Attention: Estimates refer to sliding force of two matching magnets (friction ~0.15 for Ni-Ni layer).

Extremely neodym field poses a serious hazard to electronics as well as medical implants. These neodymiums produce a flux that destroys function of sensitive medical devices. Remember: the unseen radiation passes through tissues and housings. Special caution must be taken by people with cochlear implants and drug dispensers. Also at risk are: mechanical watches, remotes, membranes, and displays. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Neodymium magnets are prone to chipping – a violent impact against metal risks their cracking. Pay attention to connection velocity – a neodymium left loose turns into a projectile. Kinetic force can cause material chips or dangerous crushing to fingers. Be sure to control the product during mounting so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h almost guarantees destruction of the neodymium. Wear eye protection 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!

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

1. Sliding resistance

*Warning: On a vertical wall, the magnet holds only approx. 20-30% of its perpendicular strength.

2. Efficiency vs thickness

*Thin metal sheet (e.g. computer case) significantly weakens the holding force.

3. Thermal stability

*For N38 material, 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

The chart above illustrates the magnetic characteristics of the material within the second quadrant of the hysteresis loop. 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. As a block magnet with high power (approx. 0.56 kg), this product is available off-the-shelf from our warehouse in Poland. 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 care, 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 magnetic separators and linear motors. 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 workshop organization on strips and for advanced DIY and modeling projects, where precision and power count.

For mounting flat magnets MPL 20x10x1 / N38, it is best to use strong epoxy glues (e.g., UHU Endfest, Distal), which ensure a durable bond with metal or plastic. 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.

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. 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. 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 protective [NiCuNi] coating secures the magnet against corrosion.

Strengths and weaknesses of neodymium magnets.

Pros

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

Their power is durable, and after approximately 10 years it decreases only by ~1% (theoretically),
They show high resistance to demagnetization induced by presence of other magnetic fields,
By using a lustrous layer of gold, the element gains an modern look,
The surface of neodymium magnets generates a strong 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 form) at temperatures up to 230°C and above...
Thanks to freedom in designing and the capacity to modify to client solutions,
Key role in innovative solutions – they are commonly used in hard drives, motor assemblies, medical devices, and multitasking production systems.
Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Disadvantages

Cons of neodymium magnets: tips and applications.

They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also increases its resistance to damage
NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
Magnets exposed to a humid environment can rust. Therefore during using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
Due to limitations in creating threads and complex shapes in magnets, we propose using a housing - magnetic mechanism.
Potential hazard to health – tiny shards of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child health protection. Furthermore, small components of these magnets can disrupt the diagnostic process medical in case of swallowing.
Due to expensive raw materials, their price is relatively high,

Holding force characteristics

Highest magnetic holding force – what it depends on?

The declared magnet strength represents the maximum value, recorded under ideal test conditions, specifically:

with the application of a yoke made of special test steel, guaranteeing full magnetic saturation
whose transverse dimension equals approx. 10 mm
characterized by smoothness
with direct contact (no paint)
during detachment in a direction perpendicular to the mounting surface
at temperature room level

Lifting capacity in real conditions – factors

It is worth knowing that the application force will differ influenced by the following factors, in order of importance:

Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
Force direction – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the maximum value.
Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
Steel grade – ideal substrate is pure iron steel. Hardened steels may attract less.
Base smoothness – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
Operating temperature – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and in frost gain strength (up to a certain limit).

Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the holding force is lower. In addition, even a small distance between the magnet and the plate lowers the load capacity.

Safety rules for work with NdFeB magnets

Do not overheat magnets

Control the heat. Heating the magnet above 80 degrees Celsius will ruin its properties and pulling force.

Safe operation

Exercise caution. Rare earth magnets act from a distance and snap with massive power, often faster than you can move away.

Nickel allergy

Certain individuals experience a contact allergy to Ni, which is the common plating for neodymium magnets. Frequent touching may cause a rash. It is best to use safety gloves.

Threat to navigation

Be aware: neodymium magnets produce a field that confuses precision electronics. Maintain a safe distance from your phone, device, and GPS.

Electronic hazard

Intense magnetic fields can corrupt files on payment cards, hard drives, and other magnetic media. Stay away of min. 10 cm.

Bone fractures

Big blocks can smash fingers instantly. Under no circumstances put your hand between two attracting surfaces.

Machining danger

Mechanical processing of NdFeB material poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.

Pacemakers

Warning for patients: Powerful magnets affect medical devices. Keep at least 30 cm distance or request help to handle the magnets.

Beware of splinters

Neodymium magnets are ceramic materials, which means they are very brittle. Impact of two magnets will cause them breaking into shards.

This is not a toy

Always keep magnets away from children. Choking hazard is significant, and the effects of magnets connecting inside the body are life-threatening.
