Grip strength drops drastically per each millimeter of gap. Remember that even a very thin break (e.g., dirt, varnish, dust) noticeably reduces the pull force. Magnets work most effectively during direct contact; distance weakens the power. Observe how quickly the parameters drop, when the magnet does not adhere tightly to the metal substrate. When planning the mounting, eliminate unnecessary gaps.

The table below indicates the theoretical holding capacity necessary to start the sliding of the magnet vertically against a upright steel wall (assuming typical friction). This value is relative to the gap size between the magnet and the metal.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces
MPL 40x15x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	3.41 kg / 7.51 lbs 3405.0 g / 33.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	2.27 kg / 5.00 lbs 2270.0 g / 22.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	1.14 kg / 2.50 lbs 1135.0 g / 11.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	5.68 kg / 12.51 lbs 5675.0 g / 55.7 N

When hanging a holder on a vertical wall (e.g., a car body), it you can count on only approx. 20%-30% of nominal attraction strength. Gravitational force as well as a weak degree of grip mean that products move down easier than they pull off. Designing a wall mount? Remember that the shear force is much weaker than the maximum static pull force. On a smooth steel, the magnet will give way down under a much lighter cargo. Application of an anti-slip coating can effectively raise the stability.

A thin sheet is incapable of absorb the full magnetic flux, which squanders power of the magnet. If you attach a powerful product to a weak sheet, the flux will pass right through and the pull force will drop sharply. To squeeze full efficiency of this magnet's potential, you need a suitably thick backing of steel. The saturation phenomenon means that on thin elements (e.g., car bodies), the magnet holds weaker. We suggest choosing the steel dimension according to the table below.

Classic neodymiums lose parameters after exceeding the maximum temperature. Watch out for overheating – excessive heat can permanently destroy this product. As the temperature rises, the magnet's capacity momentarily drops. Avoid using this product in hot environments exceeding its working range. Ignoring the limit will result in irreversible degradation of magnetic properties.

*Important note: Temperature resistance is determined by both grade, and the Permeance Coefficient Pc. Flat magnets (low permeance coefficient) risk losing magnetic properties under lower heat stress compared to rod magnets. Red status in the table indicates permanent field degradation for this particular item.

Two magnets attract each other from a wider radius than a neodymium and metal setup. The setup of magnet-to-magnet produces a massive flux and a larger range of operation. Designing a powerful holder? Apply two magnets instead of a neodymium and a steel. Remember that when connecting a pair of magnets, the collision energy is huge. The levitation is a bit weaker than the attraction, but still impressive.
*Field value in repulsion mode reaches ~0 Gs at the geometric center of the gap (due to field cancellation).
* Figures demonstrate friction force of two same neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

Extremely neodym field is a serious hazard to electronics as well as medical implants. These neodymiums produce a flux that disrupts operation of digital equipment. Remember: the unseen radiation passes through tissues and plastic. Special caution must be exercised by people with cochlear implants and drug dispensers. Also at risk are: automatic timepieces, car keys, speakers, and screens. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Neodymium magnets are delicate – a collision with steel can result in shattering. Watch the impact speed – a magnet released freely turns into a projectile. Striking energy can trigger coating fragments or injury to skin. Always hold the magnet during installation so it doesn't hit with great force against the steel surface. A collision at high speed almost guarantees destruction of the magnet. Use safety goggles when handling with large magnets.

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

Water displaces steel, making heavy objects slightly lighter. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Shear force

*Caution: On a vertical surface, the magnet holds only ~20% of its max power.

2. Efficiency vs thickness

*Thin steel (e.g. 0.5mm PC case) significantly reduces the holding force.

3. Heat tolerance

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.26

The chart above illustrates the magnetic characteristics of the material within the second quadrant of the hysteresis loop. 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 a very powerful plate magnet made of NdFeB material, which, with dimensions of 40x15x5 mm and a weight of 22.5 g, guarantees premium class connection. This magnetic block with a force of 111.37 N is ready for shipment in 24h, allowing for rapid realization of your project. Additionally, its Ni-Cu-Ni coating protects 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 40x15x5 / 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. Thanks to the flat surface and high force (approx. 11.35 kg), they are ideal as closers 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 40x15x5 / N38, it is best to use strong epoxy glues (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 (40x15 mm), which is ideal for flat mounting. 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: 40 mm (length), 15 mm (width), and 5 mm (thickness). The key parameter here is the holding force amounting to approximately 11.35 kg (force ~111.37 N), which, with such a flat shape, proves the high power of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Pros and cons of neodymium magnets.

Pros

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

They do not lose magnetism, even after nearly 10 years – the decrease in power is only ~1% (theoretically),
Magnets very well defend themselves against demagnetization caused by ambient magnetic noise,
A magnet with a shiny gold surface has better aesthetics,
Magnets possess impressive magnetic induction on the active area,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
Thanks to modularity in shaping and the ability to customize to unusual requirements,
Universal use in advanced technology sectors – they are commonly used in data components, electromotive mechanisms, diagnostic systems, also complex engineering applications.
Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,

Disadvantages

Disadvantages of neodymium magnets:

To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
Neodymium magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape as well as 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
They oxidize in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
We recommend casing - magnetic mechanism, due to difficulties in producing threads inside the magnet and complicated forms.
Potential hazard to health – tiny shards of magnets pose a threat, if swallowed, which is particularly important in the context of child health protection. Additionally, small components of these products can complicate diagnosis medical when they are in the body.
Due to complex production process, their price exceeds standard values,

Holding force characteristics

Magnetic strength at its maximum – what it depends on?

The specified lifting capacity represents the peak performance, measured under optimal environment, meaning:

using a base made of low-carbon steel, acting as a circuit closing element
whose thickness equals approx. 10 mm
with a plane free of scratches
without any insulating layer between the magnet and steel
for force acting at a right angle (pull-off, not shear)
at temperature room level

Determinants of lifting force in real conditions

In real-world applications, the actual lifting capacity results from many variables, listed from the most important:

Space between surfaces – every millimeter of separation (caused e.g. by veneer or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
Force direction – catalog parameter refers to detachment vertically. When attempting to slide, the magnet holds significantly lower power (typically approx. 20-30% of nominal force).
Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
Material composition – different alloys reacts the same. High carbon content weaken the attraction effect.
Surface structure – the more even the plate, the better the adhesion and stronger the hold. Roughness acts like micro-gaps.
Thermal environment – temperature increase results in weakening of induction. It is worth remembering the thermal limit for a given model.

Lifting capacity testing was conducted on a smooth plate of optimal thickness, under perpendicular forces, however under shearing force the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.

Precautions when working with neodymium magnets

Health Danger

People with a ICD must keep an safe separation from magnets. The magnetic field can interfere with the operation of the life-saving device.

Bodily injuries

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

Threat to navigation

Be aware: neodymium magnets produce a field that interferes with sensitive sensors. Maintain a safe distance from your phone, tablet, and navigation systems.

Swallowing risk

Adult use only. Small elements pose a choking risk, leading to severe trauma. Keep out of reach of kids and pets.

Conscious usage

Exercise caution. Neodymium magnets attract from a distance and connect with huge force, often faster than you can move away.

Magnetic media

Very strong magnetic fields can destroy records on payment cards, hard drives, and other magnetic media. Maintain a gap of at least 10 cm.

Fragile material

Beware of splinters. Magnets can explode upon violent connection, launching sharp fragments into the air. Wear goggles.

Heat sensitivity

Do not overheat. NdFeB magnets are susceptible to heat. If you need resistance above 80°C, ask us about special high-temperature series (H, SH, UH).

Flammability

Powder produced during cutting of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.

Nickel coating and allergies

Nickel alert: The Ni-Cu-Ni coating contains nickel. If an allergic reaction occurs, cease working with magnets and wear gloves.
