Magnetic force drops significantly with every subsequent millimeter of distance. Remember that even a microscopic distance (e.g., contamination, paint, dust) strongly reduces the pull force. Magnetic products operate optimally during direct contact; distance kills the power. Notice how rapidly the load capacity plummet, when the product does not touch tightly to the steel surface. When calculating the assembly, avoid additional spacers.

The following data indicates the estimated shear load necessary to cause the slippage of the magnet downwards along a vertical steel plate (assuming typical friction). This value is relative to the gap size between the magnet and the surface.

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	2.25 kg / 4.95 pounds 2247.0 g / 22.0 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.50 kg / 3.30 pounds 1498.0 g / 14.7 N

When placing a magnet on a vertical plane (e.g., a car body), it you can count on barely approx. 1/5 of its maximum pull force. Gravitational force as well as a weak degree of grip mean that products slip faster than they pull off. Designing a wall mount? Consider that the sliding force is noticeably lower than the perpendicular breakaway force. On a smooth steel, the holder will slip down under a significantly smaller load. Utilizing a rubberized layer can effectively increase the grip.

A thin metal plate is incapable of take in the full magnetic flux, which squanders power of the holder. If you attach a powerful product to a weak sheet, the magnetism will pass right through and the holding will be smaller. To squeeze 100% of this magnet's power, you require a sufficiently solid piece of metal. The saturation effect causes that on delicate walls (e.g., thin profiles), the magnet holds weaker. We advise picking the steel dimension based on the following data.

Ordinary NdFeB products irreversibly lose strength after exceeding the maximum temperature. Watch out for overheating – heat can permanently destroy this product. With every degree above norm, the neodymium's capacity briefly lowers. Refrain from using this product close to heaters exceeding its safe range. Too high temperature will result in destruction of magnetism.

*Important note: Heat tolerance is determined by both grade, and the Permeance Coefficient Pc. Low-profile magnets (low Pc) are more susceptible to demagnetization at lower temperatures than taller cylinders. The danger warning in the table points to a risk of irreversible loss for this particular item.

Two strong neodymiums interact from a significantly greater distance than a magnet and steel combination. The setup of two magnets creates a more powerful interaction and a further horizon of action. Want to build a solid fastener? Apply two magnets instead of a neodymium and a steel. Be careful that when bringing together two magnets, the impact force is huge. The repulsion force is slightly lower than the connection force, but still impressive.
*Field value in repulsion mode is approximately ~0 Gs at the geometric center of the gap (caused by magnetic field nullification).
Important: Figures demonstrate shear force of a pair of matching magnets (friction coefficient ~0.15 for Ni-Ni plating).

A strong magnetic field poses a serious hazard to IT equipment and medical implants. These NdFeB products generate a field that destroys function of digital equipment. Be aware: the invisible magnetic field acts through matter and plastic. Exceptional care must be taken by people with hearing aids and drug dispensers. The risk also applies to: mechanical watches, remotes, speakers, and displays. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

Neodymium magnets are delicate – a violent impact against metal risks their cracking. Watch the impact speed – a neodymium left loose becomes dangerous. Kinetic force can trigger coating fragments or painful pinches to skin. Hold the magnet firmly 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. 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.

In water, the magnet feels stronger thanks to Archimedes' principle. However, remember the water resistance when pulling the rope quickly.

1. Shear force

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

2. Steel thickness impact

*Thin steel (e.g. 0.5mm PC case) severely weakens the holding force.

3. Thermal stability

*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) = 0.38

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 25x10x5 mm and a weight of 9.38 g, guarantees the highest quality connection. As a magnetic bar with high power (approx. 7.49 kg), this product is available immediately from our warehouse in Poland. Additionally, 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. Watch your fingers! Magnets with a force of 7.49 kg can pinch very hard and cause hematomas. Using a screwdriver risks destroying the coating and permanently cracking the magnet.

Plate magnets MPL 25x10x5 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. Thanks to the flat surface and high force (approx. 7.49 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.

Cyanoacrylate glues (super glue type) are good only for small magnets; for larger plates, we recommend resins. 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 25x10x5 / N38 model is magnetized axially (dimension 5 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.

This model is characterized by dimensions 25x10x5 mm, which, at a weight of 9.38 g, makes it an element with high energy density. It is a magnetic block with dimensions 25x10x5 mm and a self-weight of 9.38 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Pros and cons of neodymium magnets.

Strengths

Besides their tremendous pulling force, neodymium magnets offer the following advantages:

They retain full power for nearly 10 years – the loss is just ~1% (based on simulations),
Magnets very well defend themselves against demagnetization caused by ambient magnetic noise,
A magnet with a smooth nickel surface is more attractive,
The surface of neodymium magnets generates a powerful magnetic field – this is a distinguishing feature,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
Possibility of precise creating and modifying to defined applications,
Universal use in future technologies – they are used in hard drives, electromotive mechanisms, advanced medical instruments, as well as multitasking production systems.
Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,

Limitations

Disadvantages of NdFeB magnets:

At strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (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 very resistant to heat
They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
We recommend cover - magnetic mount, due to difficulties in creating nuts inside the magnet and complex forms.
Health risk resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. Additionally, small elements of these devices can disrupt the diagnostic process medical after entering the body.
With mass production the cost of neodymium magnets is economically unviable,

Holding force characteristics

Maximum lifting force for a neodymium magnet – what it depends on?

The specified lifting capacity concerns the maximum value, measured under optimal environment, specifically:

with the application of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
possessing a massiveness of min. 10 mm to ensure full flux closure
with a plane free of scratches
with zero gap (no impurities)
for force acting at a right angle (pull-off, not shear)
at conditions approx. 20°C

Key elements affecting lifting force

Please note that the application force will differ influenced by elements below, in order of importance:

Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by veneer or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
Steel thickness – too thin plate does not accept the full field, causing part of the flux to be escaped into the air.
Metal type – not every steel reacts the same. High carbon content weaken the interaction with the magnet.
Plate texture – smooth surfaces ensure maximum contact, which increases force. Uneven metal weaken the grip.
Temperature – heating the magnet results in weakening of force. Check the maximum operating temperature for a given model.

Lifting capacity was determined by applying a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas 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.

Safe handling of NdFeB magnets

Thermal limits

Control the heat. Exposing the magnet to high heat will destroy its properties and strength.

Serious injuries

Pinching hazard: The attraction force is so immense that it can cause hematomas, pinching, and broken bones. Protective gloves are recommended.

Fire risk

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

Nickel coating and allergies

Nickel alert: The nickel-copper-nickel coating consists of nickel. If an allergic reaction occurs, cease handling magnets and use protective gear.

Phone sensors

Navigation devices and mobile phones are extremely susceptible to magnetic fields. Direct contact with a strong magnet can decalibrate the internal compass in your phone.

Warning for heart patients

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

Handling rules

Before use, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.

Risk of cracking

Watch out for shards. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. Wear goggles.

Safe distance

Do not bring magnets close to a purse, computer, or TV. The magnetism can permanently damage these devices and erase data from cards.

Product not for children

Only for adults. Small elements pose a choking risk, causing serious injuries. Store away from children and animals.
