Grip strength decreases sharply with every subsequent millimeter of spacing. Note that even a very thin break (e.g., contamination, varnish, veneer) strongly reduces the pull force. Magnetic products hold most effectively during direct contact; air break weakens the power. Observe how quickly the parameters plummet, when the product does not touch directly to the steel surface. When calculating the mounting, discard unnecessary gaps.

The table below presents the theoretical weight limit required to initiate the shifting of the magnet vertically against a upright steel plate (considering typical friction). This value varies with the gap size between the magnet and the metal.

Table 3: Wall mounting (shearing) - behavior on slippery surfaces

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	4.62 kg / 10.19 LBS 4620.0 g / 45.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	3.08 kg / 6.79 LBS 3080.0 g / 30.2 N

Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	7.70 kg / 16.98 LBS 7700.0 g / 75.5 N

When hanging a magnet on a vertical plane (e.g., a fridge), it will maintain only approx. 20%-30% of nominal attraction strength. Gravity as well as a weak degree of grip cause that magnets slip faster than they pull off. Want to create a hanger? Consider that the shear force is significantly lower than the maximum static pull force. On a painted metal, the magnet will give way down under a noticeably lighter load. Utilizing a rubberized layer can drastically improve the result.

12 mm	100%	15.40 kg / 33.95 LBS 15400.0 g / 151.1 N

A thin metal plate is incapable of focus the entire magnetic field, which squanders power of the magnet. Should you install a neodymium to a weak sheet, the magnetism will pass right through and the holding will be smaller. To achieve full efficiency of this magnet's potential, you require a sufficiently solid piece of steel. The material oversaturation means that on sheet metal structures (e.g., car bodies), the holder works worse. We recommend selecting the steel cross-section from these parameters.

Standard neodymium magnets change their properties power above the temperature limit. Avoid high temperatures – heat can permanently damage this product. With increasing heat, the neodymium's force momentarily drops. Refrain from using this magnet close to ovens exceeding its working range. Too high temperature will cause irreversible degradation of magnetism.

*Important note: Heat tolerance depends not only on the material grade, but also on the magnet's shape. Flat magnets (low permeance coefficient) risk losing magnetic properties sooner compared to rod magnets. The danger warning in the table indicates permanent field degradation for this specific geometry.

Two strong neodymiums attract each other from a much further distance than a magnet and steel setup. The connection of magnet-to-magnet creates a more powerful interaction and a larger range of performance. Designing a powerful holder? Apply two magnets instead of a neodymium and a striker plate. Remember that when bringing together two magnets, the pinch force is extreme. The repulsion force is slightly lower than the connection force, but still large.
*Flux density for N-N configuration drops to ~0 Gs at the geometric center between the magnets (caused by magnetic field nullification).
Important: Figures demonstrate shear force of dual identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni plating).

Powerful magnet radiation poses a real danger to IT equipment and medical implants. These neodymiums produce a field that disrupts operation of digital equipment. Remember: the unseen radiation passes through tissues and housings. Special caution must be exercised by people with hearing aids and insulin pumps. Influence will be felt by: mechanical watches, remotes, speakers, and screens. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

Table 8: Impact energy (cracking risk) - collision effects
MPL 20x20x20 / N38

Start from (mm)	Speed (km/h)	Energy (J)

50 mm	36.13 km/h (10.04 m/s)	3.02 J
100 mm	51.09 km/h (14.19 m/s)	6.04 J

Magnetic elements are very brittle – a collision with steel risks their cracking. Pay attention to connection velocity – a magnet released freely turns into a projectile. Striking energy can trigger coating fragments or painful pinches to skin. Be sure to control the product during bringing near metal so it doesn't hit with great force against the steel surface. A contact at a velocity of dozens of km/h means shattering of the magnet. Wear eye protection when handling with large magnets.

Corrosion warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

In water, the magnet feels stronger thanks to Archimedes' principle. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Shear force

*Warning: On a vertical wall, the magnet retains merely a fraction of its max power.

2. Steel thickness impact

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

3. Thermal stability

*For N38 material, the critical limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.84

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.

165.00 ZŁ brutto / pcs

This product is an extremely strong magnet in the shape of a plate made of NdFeB material, which, with dimensions of 20x20x20 mm and a weight of 60 g, guarantees premium class connection. As a block magnet with high power (approx. 15.40 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 20x20x20 / 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. Using a screwdriver risks destroying the coating and permanently cracking the magnet.

They constitute a key element in the production of wind generators and material handling systems. They work great as invisible mounts under tiles, wood, or glass. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.

For mounting flat magnets MPL 20x20x20 / 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. 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 20x20x20 / N38 model is magnetized axially (dimension 20 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 20x20x20 mm, which, at a weight of 60 g, makes it an element with high energy density. It is a magnetic block with dimensions 20x20x20 mm and a self-weight of 60 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Strengths and weaknesses of Nd₂Fe₁₄B magnets.

Advantages

Besides their durability, neodymium magnets are valued for these benefits:

They have stable power, and over nearly ten years their attraction force decreases symbolically – ~1% (in testing),
They maintain their magnetic properties even under close interference source,
A magnet with a smooth silver surface has an effective appearance,
They show high magnetic induction at the operating surface, which improves attraction properties,
Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
Thanks to the possibility of free forming and customization to individualized solutions, magnetic components can be produced in a variety of geometric configurations, which increases their versatility,
Huge importance in modern technologies – they are used in data components, drive modules, diagnostic systems, and technologically advanced constructions.
Thanks to their power density, small magnets offer high operating force, occupying minimum space,

Limitations

Disadvantages of NdFeB magnets:

To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
Magnets exposed to a humid environment can rust. Therefore during using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
Limited ability of creating nuts in the magnet and complex shapes - recommended is a housing - mounting mechanism.
Possible danger related to microscopic parts of magnets pose a threat, in case of ingestion, which gains importance in the aspect of protecting the youngest. It is also worth noting that small elements of these magnets can complicate diagnosis medical in case of swallowing.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Pull force analysis

Breakaway strength of the magnet in ideal conditions – what affects it?

Holding force of 15.40 kg is a result of laboratory testing performed under specific, ideal conditions:

on a plate made of mild steel, optimally conducting the magnetic flux
whose thickness equals approx. 10 mm
with a plane free of scratches
with direct contact (without impurities)
for force acting at a right angle (in the magnet axis)
at ambient temperature room level

Key elements affecting lifting force

Bear in mind that the magnet holding may be lower influenced by the following factors, starting with the most relevant:

Clearance – the presence of foreign body (rust, tape, air) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
Force direction – catalog parameter refers to pulling vertically. When attempting to slide, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
Steel thickness – insufficiently thick steel does not close the flux, causing part of the flux to be escaped into the air.
Steel grade – the best choice is pure iron steel. Cast iron may have worse magnetic properties.
Base smoothness – the smoother and more polished the plate, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
Temperature – heating the magnet results in weakening of force. It is worth remembering the thermal limit for a given model.

Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under parallel forces the load capacity is reduced by as much as fivefold. Additionally, even a slight gap between the magnet’s surface and the plate decreases the lifting capacity.

H&S for magnets

Do not give to children

Always keep magnets out of reach of children. Risk of swallowing is significant, and the effects of magnets clamping inside the body are fatal.

Bodily injuries

Risk of injury: The attraction force is so immense that it can cause blood blisters, crushing, and even bone fractures. Use thick gloves.

Do not drill into magnets

Powder created during grinding of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.

Pacemakers

Medical warning: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.

Shattering risk

Despite metallic appearance, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.

Immense force

Exercise caution. Rare earth magnets attract from a distance and snap with huge force, often quicker than you can react.

Impact on smartphones

An intense magnetic field negatively affects the operation of magnetometers in smartphones and GPS navigation. Do not bring magnets near a smartphone to prevent breaking the sensors.

Demagnetization risk

Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will destroy its properties and strength.

Avoid contact if allergic

Nickel alert: The Ni-Cu-Ni coating contains nickel. If skin irritation happens, immediately stop handling magnets and use protective gear.
