Magnetic force decreases sharply per each millimeter of spacing. Note that even the smallest gap (e.g., dirt, varnish, dust) strongly diminishes the holding power. Magnetic products hold strongest during direct contact; gap nullifies the force. Analyze how quickly the parameters fall, when the magnet does not adhere flatly to the steel surface. When calculating the mounting, avoid redundant distances.

The following data shows the theoretical weight limit sufficient to initiate the sliding of the magnet downwards against a vertical steel plate (assuming typical friction). This value depends on the air gap between the magnet and the surface.

Table 3: Vertical assembly (sliding) - vertical pull
MPL 5x5x2 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.23 kg / 0.51 lbs 231.0 g / 2.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.15 kg / 0.34 lbs 154.0 g / 1.5 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.08 kg / 0.17 lbs 77.0 g / 0.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.39 kg / 0.85 lbs 385.0 g / 3.8 N

When hanging a element on a vertical wall (e.g., a car body), it will maintain only approx. 1/5 of its nominal power. Gravitational force as well as a weak degree of grip cause that holders move down faster than they pull off. Planning a vertical fastening? Remember that the shear force is much weaker than the perpendicular breakaway force. On a painted metal, the magnet will give way down under a significantly smaller cargo. Application of an anti-slip coating can effectively increase the grip.

12 mm	100%	0.77 kg / 1.70 lbs 770.0 g / 7.6 N

A thin metal plate is not enough to conduct the entire magnetic field, which wastes potential of the holder. If you mount a strong magnet to a weak sheet, the field will penetrate right through and the pull force will drop sharply. To utilize the maximum of this neodymium's power, you require a sufficiently solid backing of steel. The saturation phenomenon causes that on thin elements (e.g., thin profiles), the holder works worse. We recommend selecting the steel cross-section according to the table below.

Table 5: Thermal stability (material behavior) - resistance threshold
MPL 5x5x2 / N38

100 °C	-28.8%	0.55 kg / 1.21 lbs 548.2 g / 5.4 N

Classic neodymiums irreversibly lose parameters past the thermal threshold. Protect against heat – heat can permanently damage this product. With increasing heat, the neodymium's capacity temporarily lowers. Avoid using this product close to ovens higher than its operating temperature limit. Ignoring the limit will lead to irreversible degradation of magnetic properties.

*Technical advisory: Thermal stability depends not only on the material grade, as well as the dimension ratios. Flat magnets (pancake types) are more susceptible to demagnetization sooner compared to rod magnets. Warning indicator in the table signals permanent field degradation for this specific geometry.

Two strong neodymiums interact from a significantly greater distance than a magnet and sheet combination. The connection of magnet-to-magnet creates a more powerful interaction and a larger range of performance. Designing a strong closure? Utilize two neodymiums instead of one magnet and a steel. Remember that when connecting a pair of magnets, the impact force is extreme. The repulsion force is marginally weaker than the connection force, but still impressive.
*The magnetic induction in repulsion mode is approximately ~0 Gs at the midpoint of the gap (resulting from vector opposition).
Attention: Estimates demonstrate shear force of two identical neodymium magnets (friction ~0.15 for Ni-Ni layer).

Extremely neodym field is a real danger to IT equipment as well as medical implants. These NdFeB products generate a field that destroys function of digital equipment. Notice: the invisible magnetic field penetrates the body and plastic. Exceptional care must be exercised by people with cochlear implants and drug dispensers. Influence will be felt by: mechanical watches, remotes, membranes, and displays. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Magnetic elements are very brittle – a violent impact against metal can result in shattering. Watch the impact speed – a magnet released freely speeds with massive force. Striking energy can destroy the magnet or dangerous crushing to fingers. Always hold the magnet during bringing near metal so it doesn't hit violently against the steel surface. A contact at a velocity of dozens of km/h means shattering of the magnet. Wear safety glasses when playing with powerful specimens.

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

Contrary to myths, water does not block the magnetic field. Buoyancy helps in lifting finds.

1. Vertical hold

*Note: On a vertical wall, the magnet holds just ~20% of its max power.

2. Efficiency vs thickness

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

3. Thermal stability

*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) = 0.46

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 an extremely strong magnet in the shape of a plate made of NdFeB material, which, with dimensions of 5x5x2 mm and a weight of 0.38 g, guarantees premium class connection. As a block magnet with high power (approx. 0.77 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 strong flat magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. To separate the MPL 5x5x2 / 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. Never use metal tools for prying, as the brittle NdFeB material may chip and damage your eyes.

Plate magnets MPL 5x5x2 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. Thanks to the flat surface and high force (approx. 0.77 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.

For mounting flat magnets MPL 5x5x2 / N38, it is best to use two-component adhesives (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. 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 (5x5 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 5x5x2 mm, which, at a weight of 0.38 g, makes it an element with high energy density. It is a magnetic block with dimensions 5x5x2 mm and a self-weight of 0.38 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Strengths as well as weaknesses of rare earth magnets.

Advantages

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

Their magnetic field remains stable, and after around 10 years it decreases only by ~1% (theoretically),
Magnets perfectly protect themselves against demagnetization caused by ambient magnetic noise,
The use of an metallic coating of noble metals (nickel, gold, silver) causes the element to look better,
Magnetic induction on the top side of the magnet remains maximum,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
Possibility of detailed shaping and modifying to specific applications,
Wide application in high-tech industry – they are used in hard drives, motor assemblies, diagnostic systems, as well as technologically advanced constructions.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in small systems

Limitations

Problematic aspects of neodymium magnets and proposals for their use:

To avoid cracks under impact, we recommend using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (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
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 prevent oxidation as well as corrosion.
We suggest a housing - magnetic mechanism, due to difficulties in producing threads inside the magnet and complex forms.
Potential hazard related to microscopic parts of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child safety. Additionally, tiny parts of these devices can be problematic in diagnostics medical when they are in the body.
With budget limitations the cost of neodymium magnets can be a barrier,

Lifting parameters

Best holding force of the magnet in ideal parameters – what it depends on?

Information about lifting capacity was determined for optimal configuration, taking into account:

with the application of a yoke made of low-carbon steel, ensuring full magnetic saturation
whose thickness equals approx. 10 mm
characterized by lack of roughness
with total lack of distance (without impurities)
under perpendicular force direction (90-degree angle)
at temperature approx. 20 degrees Celsius

Impact of factors on magnetic holding capacity in practice

Holding efficiency impacted by specific conditions, including (from most important):

Clearance – the presence of foreign body (paint, dirt, air) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
Angle of force application – highest force is obtained only during perpendicular pulling. The resistance to sliding of the magnet along the plate is usually many times lower (approx. 1/5 of the lifting capacity).
Base massiveness – too thin steel causes magnetic saturation, causing part of the power to be lost to the other side.
Material type – ideal substrate is high-permeability steel. Stainless steels may generate lower lifting capacity.
Smoothness – full contact is obtained only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
Heat – neodymium magnets have a sensitivity to temperature. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).

Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the load capacity is reduced by as much as fivefold. In addition, even a small distance between the magnet and the plate reduces the load capacity.

Safety rules for work with NdFeB magnets

Nickel allergy

Some people experience a sensitization to nickel, which is the typical protective layer for NdFeB magnets. Frequent touching can result in a rash. It is best to use safety gloves.

Do not drill into magnets

Fire hazard: Rare earth powder is explosive. Do not process magnets in home conditions as this risks ignition.

Hand protection

Watch your fingers. Two large magnets will snap together instantly with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!

Pacemakers

Health Alert: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.

Impact on smartphones

A strong magnetic field disrupts the operation of magnetometers in smartphones and GPS navigation. Do not bring magnets near a device to prevent breaking the sensors.

Demagnetization risk

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

Handling guide

Handle magnets with awareness. Their immense force can surprise even professionals. Be vigilant and do not underestimate their force.

Threat to electronics

Do not bring magnets near a wallet, laptop, or TV. The magnetic field can irreversibly ruin these devices and erase data from cards.

Danger to the youngest

Absolutely store magnets away from children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are tragic.

Protective goggles

Despite the nickel coating, the material is delicate and cannot withstand shocks. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
