Grip strength weakens drastically with every subsequent millimeter of gap. Note that even a very thin break (e.g., contamination, varnish, rust) noticeably diminishes the holding power. Magnetic products operate strongest during direct contact; distance kills the power. Analyze how flashily the parameters drop, when the product does not touch flatly to the metal substrate. When calculating the arrangement, avoid unnecessary gaps.

The following data presents the estimated force needed to initiate the shifting of the magnet vertically on a upright metal surface (considering typical friction coefficient). This value varies with the gap size between the magnet and the metal.

Table 3: Wall mounting (sliding) - vertical pull
MPL 20x8x6 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	1.88 kg / 4.15 pounds 1881.0 g / 18.5 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.25 kg / 2.76 pounds 1254.0 g / 12.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.63 kg / 1.38 pounds 627.0 g / 6.2 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	3.14 kg / 6.91 pounds 3135.0 g / 30.8 N

When hanging a element on a vertical surface (e.g., a car body), it will only hold barely about 1/5 of its nominal power. Gravitational force as well as a low friction coefficient mean that products move down easier than they pop off the substrate. Want to create a vertical fastening? Remember that the shear force is significantly lower than the perpendicular breakaway force. On a painted metal, the magnet will slide down under a noticeably lighter weight. Using a rubber pad can drastically increase the grip.

A thin metal plate is incapable of conduct the entire magnetic field, which wastes potential of the magnet. If you mount a strong magnet to a too thin substrate, the field will pass right through and the holding will be smaller. To achieve the maximum of this neodymium's potential, you require a sufficiently solid piece of metal. The material oversaturation causes that on delicate walls (e.g., thin profiles), the product holds weaker. We recommend selecting the steel thickness from these parameters.

Classic neodymiums lose strength past the thermal threshold. Watch out for overheating – heat can permanently damage this product. As the temperature rises, the magnet's force briefly drops. Refrain from using this product near heat sources higher than its safe range. Ignoring the limit will lead to permanent loss of magnetism.

*Technical advisory: Thermal stability depends not only on the material grade, as well as the dimension ratios. Thin magnets (low permeance coefficient) may lose charge permanently at lower temperatures compared to rod magnets. The danger warning in the table points to permanent field degradation for this specific geometry.

Two magnetic products attract each other from a wider radius than a magnet and sheet setup. Such a system of two magnets creates a more powerful interaction and a further horizon of action. Planning to create a powerful holder? Use a pair of magnets instead of one magnet and a striker plate. Remember that when attracting two neodymiums, the collision energy is huge. The levitation is a bit weaker than the connection force, but still impressive.
*The magnetic induction in repulsion mode is approximately ~0 Gs at the geometric center between the magnets (caused by magnetic field nullification).
Important: Results refer to friction force of dual same neodymium magnets (friction ~0.15 for Ni-Ni layer).

Extremely neodym field is a large risk to electronic devices and medical implants. These neodymiums produce a field that destroys function of sensitive medical devices. Be aware: the unseen radiation passes through tissues and glass. Increased vigilance must be exercised by people with cochlear implants and insulin pumps. The risk also applies to: automatic timepieces, remotes, speakers, and screens. Do not bring the product near payment cards, hard drives, or sensitive navigation tools.

Magnetic elements are prone to chipping – a strong collision with metal can result in shattering. Control the attraction moment – a magnet released freely turns into a projectile. Kinetic force can trigger coating fragments or dangerous crushing to fingers. Always hold the magnet during installation so it doesn't hit with great force against the metal. A collision at high speed ends with a crack of the neodymium. Wear safety glasses when playing with large magnets.

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

Water displaces steel, making heavy objects slightly lighter. Buoyancy helps in lifting finds.

1. Shear force

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

2. Efficiency vs thickness

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

3. Heat tolerance

*For standard magnets, the critical limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.52

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 20x8x6 mm and a weight of 7.2 g, guarantees premium class connection. As a magnetic bar with high power (approx. 6.27 kg), this product is available off-the-shelf from our warehouse in Poland. Furthermore, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, giving it an aesthetic appearance.

Separating block magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. To separate the MPL 20x8x6 / 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 20x8x6 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. Thanks to the flat surface and high force (approx. 6.27 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 20x8x6 / N38, it is best to use strong epoxy glues (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 20x8x6 / N38 model is magnetized through the thickness (dimension 6 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 (20x8 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 20x8x6 mm, which, at a weight of 7.2 g, makes it an element with high energy density. It is a magnetic block with dimensions 20x8x6 mm and a self-weight of 7.2 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Advantages and disadvantages of Nd₂Fe₁₄B magnets.

Advantages

Besides their remarkable magnetic power, neodymium magnets offer the following advantages:

They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (in laboratory conditions),
They retain their magnetic properties even under external field action,
A magnet with a shiny silver surface is more attractive,
Magnetic induction on the surface of the magnet turns out to be extremely intense,
Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
Thanks to modularity in shaping and the capacity to customize to complex applications,
Versatile presence in advanced technology sectors – they are commonly used in hard drives, electromotive mechanisms, precision medical tools, also multitasking production systems.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which makes them useful in compact constructions

Cons

Characteristics of disadvantages of neodymium magnets: application proposals

To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
Due to limitations in producing nuts and complex forms in magnets, we recommend using casing - magnetic mount.
Possible danger to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Additionally, small elements of these products can complicate diagnosis medical when they are in the body.
High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Pull force analysis

Highest magnetic holding force – what contributes to it?

The load parameter shown represents the limit force, measured under optimal environment, namely:

using a sheet made of mild steel, functioning as a circuit closing element
whose thickness equals approx. 10 mm
with a plane cleaned and smooth
under conditions of no distance (surface-to-surface)
under perpendicular force vector (90-degree angle)
in stable room temperature

Impact of factors on magnetic holding capacity in practice

Please note that the working load will differ depending on elements below, starting with the most relevant:

Gap (betwixt the magnet and the metal), as even a tiny distance (e.g. 0.5 mm) results in a decrease in force by up to 50% (this also applies to paint, rust or debris).
Force direction – declared lifting capacity refers to pulling vertically. When slipping, the magnet holds much less (often approx. 20-30% of maximum force).
Plate thickness – insufficiently thick sheet does not accept the full field, causing part of the flux to be wasted into the air.
Steel type – low-carbon steel gives the best results. Alloy steels decrease magnetic permeability and holding force.
Surface finish – ideal contact is obtained only on polished steel. Rough texture create air cushions, weakening the magnet.
Temperature influence – high temperature reduces pulling force. Too high temperature can permanently damage the magnet.

Lifting capacity was determined using a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, whereas under shearing force the load capacity is reduced by as much as 75%. In addition, even a small distance between the magnet and the plate reduces the load capacity.

H&S for magnets

Physical harm

Large magnets can smash fingers in a fraction of a second. Never place your hand betwixt two attracting surfaces.

Data carriers

Powerful magnetic fields can destroy records on credit cards, HDDs, and other magnetic media. Keep a distance of at least 10 cm.

Risk of cracking

Beware of splinters. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. We recommend safety glasses.

Adults only

Product intended for adults. Tiny parts can be swallowed, leading to severe trauma. Store out of reach of children and animals.

Dust is flammable

Combustion risk: Neodymium dust is explosive. Do not process magnets without safety gear as this may cause fire.

Implant safety

For implant holders: Powerful magnets affect medical devices. Keep at least 30 cm distance or ask another person to handle the magnets.

Magnetic interference

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

Metal Allergy

Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If skin irritation happens, cease working with magnets and use protective gear.

Immense force

Handle magnets with awareness. Their powerful strength can shock even experienced users. Plan your moves and do not underestimate their force.

Permanent damage

Avoid heat. NdFeB magnets are susceptible to temperature. If you need operation above 80°C, ask us about HT versions (H, SH, UH).
