Magnetic force drops sharply with every subsequent millimeter of gap. Keep in mind that every additional insulation layer (e.g., contamination, paint, rust) significantly weakens the grip. Magnets hold optimally during direct contact; distance drastically cuts the power. See how quickly the pull force plummet, when the magnet does not adhere tightly to the metal substrate. When planning the assembly, discard additional spacers.

This section calculates the approximate weight limit required to cause the sliding of the magnet down on a vertical steel wall (assuming typical friction). This value is relative to the gap size between the magnet and the metal.

Table 3: Wall mounting (sliding) - vertical pull
MPL 20x8x4 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	1.44 kg / 3.17 lbs 1437.0 g / 14.1 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.96 kg / 2.11 lbs 958.0 g / 9.4 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.48 kg / 1.06 lbs 479.0 g / 4.7 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	2.40 kg / 5.28 lbs 2395.0 g / 23.5 N

When placing a element on a upright plane (e.g., a fridge), it you can count on barely approx. 1/5 of its maximum pull force. Gravity and a weak degree of grip cause that holders slide down faster than they pop off the substrate. Planning a wall mount? Consider that the shear force is noticeably lower than the maximum static pull force. On a smooth steel, the magnet will slide down under a noticeably lighter load. Application of an anti-slip pad can effectively increase the grip.

5 mm	100%	4.79 kg / 10.56 lbs 4790.0 g / 47.0 N

12 mm	100%	4.79 kg / 10.56 lbs 4790.0 g / 47.0 N

A thin sheet is not enough to absorb the entire magnetic field, which squanders power of the magnet. If you mount a strong magnet to a weak sheet, the flux will pass right through and the pull force will drop sharply. To achieve 100% of this neodymium's power, you need a suitably thick element of metal. The saturation phenomenon means that on delicate walls (e.g., thin profiles), the holder shows lower pull force. We suggest choosing the steel cross-section based on the following data.

Standard neodymium magnets irreversibly lose parameters past the thermal threshold. Protect against heat – excessive heat can irreversibly demagnetize this product. With increasing heat, the neodymium's force temporarily drops. Avoid using this product near heat sources higher than its working range. Exceeding the critical threshold will cause permanent loss of magnetic properties.

*Important note: Temperature resistance is determined by both grade, and the Permeance Coefficient Pc. Flat magnets (pancake types) risk losing magnetic properties sooner than taller cylinders. Warning indicator in the table points to permanent field degradation for this particular item.

Two magnets interact from a wider radius than a neodymium and metal setup. The setup of magnet-to-magnet creates a more powerful interaction and a larger range of performance. Want to build a powerful holder? Utilize two neodymiums instead of a neodymium and a striker plate. Be careful that when bringing together two magnets, the collision energy is huge. The levitation is a bit weaker than the attraction, but still large.
*Field value for N-N configuration drops to ~0 Gs at the midpoint of the gap (caused by magnetic field nullification).
Note: Results apply to friction force of two identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni plating).

Table 7: Safety (HSE) (implants) - precautionary measures

A strong magnetic field is a real danger to electronics and pacemakers. These NdFeB products produce a flux that destroys function of sensitive medical devices. Remember: the unseen radiation penetrates the body and plastic. Special caution must be exercised by people with hearing aids and insulin pumps. Also at risk are: automatic timepieces, car keys, membranes, and screens. Avoid contact with magnetic cards, HDD media, or sensitive navigation tools.

Table 8: Impact energy (kinetic energy) - warning
MPL 20x8x4 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	32.16 km/h (8.93 m/s)	0.19 J
30 mm	55.18 km/h (15.33 m/s)	0.56 J
50 mm	71.24 km/h (19.79 m/s)	0.94 J
100 mm	100.75 km/h (27.99 m/s)	1.88 J

Neodymium magnets are delicate – a strong collision with metal risks their cracking. Pay attention to connection velocity – a neodymium left loose becomes dangerous. Impact energy can trigger coating fragments or dangerous crushing to skin. Be sure to control the product during mounting so it doesn't slam with momentum against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Use safety goggles when playing with powerful specimens.

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

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

2. Steel thickness impact

*Thin steel (e.g. computer case) drastically limits the holding force.

3. Power loss vs temp

*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) = 0.38

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 20x8x4 mm and a weight of 4.8 g, guarantees premium class connection. As a block magnet with high power (approx. 4.79 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 block magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. To separate the MPL 20x8x4 / 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 20x8x4 / N38 are the foundation for many industrial devices, such as filters catching filings and linear motors. Thanks to the flat surface and high force (approx. 4.79 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 20x8x4 / N38, we recommend utilizing 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. Remember to clean and degrease the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

Standardly, the MPL 20x8x4 / N38 model is magnetized through the thickness (dimension 4 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.

The presented product is a neodymium magnet with precisely defined parameters: 20 mm (length), 8 mm (width), and 4 mm (thickness). The key parameter here is the holding force amounting to approximately 4.79 kg (force ~46.98 N), which, with such a flat shape, proves the high power of the material. The product meets the standards for N38 grade magnets.

Pros and cons of Nd₂Fe₁₄B magnets.

Benefits

Besides their high retention, neodymium magnets are valued for these benefits:

They do not lose magnetism, even after around 10 years – the reduction in power is only ~1% (based on measurements),
Magnets effectively defend themselves against loss of magnetization caused by external fields,
The use of an refined layer of noble metals (nickel, gold, silver) causes the element to look better,
Neodymium magnets create maximum magnetic induction on a their surface, which ensures high operational effectiveness,
Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
Thanks to modularity in shaping and the capacity to modify to individual projects,
Versatile presence in future technologies – they find application in computer drives, electric motors, precision medical tools, and technologically advanced constructions.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Weaknesses

Characteristics of disadvantages of neodymium magnets and proposals for their use:

At strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
NdFeB magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening 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 extremely resistant to heat
Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
Due to limitations in producing nuts and complex forms in magnets, we recommend using cover - magnetic holder.
Possible danger to health – tiny shards of magnets can be dangerous, in case of ingestion, which becomes key in the context of child safety. Furthermore, tiny parts of these products can disrupt the diagnostic process medical after entering the body.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Holding force characteristics

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

Breakaway force was defined for ideal contact conditions, assuming:

with the contact of a yoke made of special test steel, guaranteeing full magnetic saturation
with a thickness minimum 10 mm
with an polished touching surface
with total lack of distance (no coatings)
for force acting at a right angle (in the magnet axis)
at standard ambient temperature

Lifting capacity in practice – influencing factors

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

Gap between surfaces – every millimeter of separation (caused e.g. by varnish or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of generating force.
Material type – the best choice is pure iron steel. Stainless steels may attract less.
Surface finish – full contact is obtained only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
Operating temperature – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).

Lifting capacity was assessed with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, however under parallel forces the holding force is lower. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the load capacity.

H&S for magnets

Handling rules

Before use, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Be predictive.

Fragile material

Neodymium magnets are ceramic materials, which means they are prone to chipping. Impact of two magnets leads to them shattering into shards.

Allergy Warning

It is widely known that the nickel plating (the usual finish) is a potent allergen. If you have an allergy, refrain from direct skin contact and opt for coated magnets.

Data carriers

Avoid bringing magnets near a wallet, laptop, or TV. The magnetic field can irreversibly ruin these devices and wipe information from cards.

Implant safety

Health Alert: Neodymium magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.

Fire warning

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

Bodily injuries

Protect your hands. Two powerful magnets will join immediately with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!

Impact on smartphones

Remember: rare earth magnets generate a field that disrupts sensitive sensors. Keep a separation from your phone, device, and navigation systems.

Swallowing risk

Adult use only. Tiny parts pose a choking risk, leading to severe trauma. Store away from kids and pets.

Heat warning

Do not overheat. NdFeB magnets are sensitive to heat. If you need operation above 80°C, ask us about HT versions (H, SH, UH).
