Grip strength drops sharply with every mm of spacing. Remember that even a very thin break (e.g., contamination, varnish, rust) significantly reduces the pull force. Neodymiums work most effectively in perfect adhesion; distance nullifies the force. Notice how flashily the load capacity drop, when the product does not touch directly to the steel surface. When calculating the arrangement, discard redundant distances.

The following data defines the approximate weight limit necessary to start the slippage of the magnet vertically on a vertical steel wall (assuming typical friction coefficient). The holding force varies with the air gap between the magnet and the surface.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces
MPL 5x5x1.2 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.13 kg / 0.29 lbs 132.0 g / 1.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.09 kg / 0.19 lbs 88.0 g / 0.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.04 kg / 0.10 lbs 44.0 g / 0.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.22 kg / 0.49 lbs 220.0 g / 2.2 N

When placing a element on a upright surface (e.g., a car body), it will only hold barely approx. 20%-30% of its maximum pull force. Gravitational force as well as a low friction coefficient cause that magnets move down easier than they pull off. Want to create a wall mount? Note that the sliding force is significantly lower than the perpendicular breakaway force. On a painted metal, the element will slip down under a significantly smaller load. Application of an anti-slip coating can significantly improve the result.

12 mm	100%	0.44 kg / 0.97 lbs 440.0 g / 4.3 N

A thin sheet is unable to focus the entire magnetic field, which wastes potential of the holder. Should you mount a strong magnet to a thin surface, the field will pass right through and the attraction force will be weaker. To squeeze the maximum of this magnet's potential, you need a suitably thick element of steel. The material oversaturation means that on delicate walls (e.g., thin profiles), the magnet shows lower pull force. We advise picking the steel thickness from these parameters.

Ambient temp. (°C)	Power loss	Remaining pull (kg/lbs/g/N)	Status

100 °C	-28.8%	0.31 kg / 0.69 lbs 313.3 g / 3.1 N

Ordinary NdFeB products lose power past the thermal threshold. Watch out for overheating – excessive heat can irreversibly demagnetize this product. With increasing heat, the magnet's capacity briefly lowers. Avoid using this magnet near heat sources exceeding its working range. Ignoring the limit will cause permanent loss of magnetism.

*Important note: Heat tolerance is determined by both grade, as well as the dimension ratios. Flat magnets (pancake types) risk losing magnetic properties under lower heat stress than long magnets. The danger warning in the table indicates a risk of irreversible loss for this specific geometry.

Two magnetic products interact from a much further distance than a magnet and sheet combination. The connection of magnet-to-magnet creates a more powerful interaction and a larger range of operation. Want to build a solid fastener? Apply two magnets instead of one magnet and a striker plate. Be careful that when connecting a pair of magnets, the pinch force is massive. The repulsion force is marginally weaker than the connection force, but still impressive.
*Field value in repulsion mode reaches ~0 Gs at the geometric center between the magnets (resulting from vector opposition).
Important: Results apply to friction force of a pair of identical magnets (friction coefficient ~0.15 for Ni-Ni coating).

Extremely neodym field poses a serious hazard to electronics as well as pacemakers. These magnets produce a flux that prevents correct functioning of digital equipment. Notice: the unseen radiation passes through tissues and glass. Increased vigilance must be taken by people with hearing aids and insulin pumps. Influence will be felt by: mechanical watches, car keys, membranes, and screens. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

Neodymium magnets are prone to chipping – a violent impact against metal causes immediate chipping. Watch the impact speed – a neodymium left loose becomes dangerous. Striking energy can cause material chips or painful pinches to skin. Be sure to control the product during installation 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. Wear eye protection when handling with powerful specimens.

Corrosion 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. Buoyancy helps in lifting finds.

1. Vertical hold

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

2. Steel thickness impact

*Thin metal sheet (e.g. 0.5mm PC case) significantly weakens the holding force.

3. Temperature resistance

*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) = 0.30

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 plate magnet made of NdFeB material, which, with dimensions of 5x5x1.2 mm and a weight of 0.22 g, guarantees premium class connection. As a block magnet with high power (approx. 0.44 kg), this product is available immediately from our warehouse in Poland. Furthermore, its Ni-Cu-Ni coating protects it against corrosion in standard operating conditions, giving it an aesthetic appearance.

The key to success is sliding the magnets along their largest connection plane (using e.g., the edge of a table), which is easier than trying to tear them apart directly. To separate the MPL 5x5x1.2 / 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 5x5x1.2 / 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. 0.44 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 5x5x1.2 / 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).

Standardly, the MPL 5x5x1.2 / N38 model is magnetized through the thickness (dimension 1.2 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. Such a pole arrangement ensures maximum holding capacity when pressing against the sheet, creating a closed magnetic circuit.

The presented product is a neodymium magnet with precisely defined parameters: 5 mm (length), 5 mm (width), and 1.2 mm (thickness). It is a magnetic block with dimensions 5x5x1.2 mm and a self-weight of 0.22 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages and disadvantages of Nd₂Fe₁₄B magnets.

Pros

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

Their strength is durable, and after approximately 10 years it drops only by ~1% (theoretically),
They do not lose their magnetic properties even under close interference source,
Thanks to the shimmering finish, the coating of Ni-Cu-Ni, gold-plated, or silver gives an aesthetic appearance,
Magnetic induction on the working layer of the magnet remains very high,
Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for operation at temperatures approaching 230°C and above...
Considering the ability of accurate forming and adaptation to individualized requirements, NdFeB magnets can be manufactured in a variety of geometric configurations, which expands the range of possible applications,
Significant place in electronics industry – they find application in data components, electromotive mechanisms, advanced medical instruments, as well as other advanced devices.
Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Cons

Disadvantages of neodymium magnets:

Brittleness is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a special holder, which not only protects them against impacts but also raises their durability
Neodymium magnets lose strength 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
Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
Limited ability of producing threads in the magnet and complex forms - recommended is cover - mounting mechanism.
Possible danger resulting from small fragments of magnets can be dangerous, if swallowed, which gains importance in the context of child health protection. Additionally, small elements of these products can complicate diagnosis medical in case of swallowing.
Due to expensive raw materials, their price exceeds standard values,

Lifting parameters

Highest magnetic holding force – what affects it?

The lifting capacity listed is a result of laboratory testing performed under specific, ideal conditions:

on a plate made of structural steel, effectively closing the magnetic flux
whose transverse dimension is min. 10 mm
with an ideally smooth touching surface
under conditions of gap-free contact (surface-to-surface)
for force acting at a right angle (pull-off, not shear)
at ambient temperature approx. 20 degrees Celsius

Lifting capacity in practice – influencing factors

Effective lifting capacity is affected by specific conditions, mainly (from most important):

Space between surfaces – every millimeter of separation (caused e.g. by varnish or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
Angle of force application – maximum parameter is available only during pulling at a 90° angle. The force required to slide of the magnet along the plate is typically several times lower (approx. 1/5 of the lifting capacity).
Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of converting into lifting capacity.
Material type – the best choice is high-permeability steel. Hardened steels may generate lower lifting capacity.
Surface finish – ideal contact is obtained only on smooth steel. Any scratches and bumps create air cushions, reducing force.
Operating temperature – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).

Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate reduces the holding force.

Warnings

Thermal limits

Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will permanently weaken its properties and pulling force.

Choking Hazard

Product intended for adults. Small elements can be swallowed, leading to intestinal necrosis. Store out of reach of kids and pets.

Medical interference

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

Keep away from electronics

A powerful magnetic field interferes with the functioning of magnetometers in smartphones and GPS navigation. Do not bring magnets near a smartphone to avoid damaging the sensors.

Risk of cracking

NdFeB magnets are ceramic materials, which means they are very brittle. Collision of two magnets leads to them shattering into shards.

Sensitization to coating

Studies show that nickel (standard magnet coating) is a potent allergen. If you have an allergy, refrain from direct skin contact and opt for coated magnets.

Hand protection

Big blocks can crush fingers instantly. Do not put your hand between two strong magnets.

Do not underestimate power

Be careful. Rare earth magnets attract from a long distance and connect with massive power, often quicker than you can react.

Dust explosion hazard

Machining of neodymium magnets carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.

Threat to electronics

Very strong magnetic fields can destroy records on payment cards, HDDs, and storage devices. Keep a distance of min. 10 cm.
