Pulling power decreases drastically with every mm of spacing. Keep in mind that even the smallest gap (e.g., contamination, paint, dust) significantly diminishes the holding power. Magnets operate optimally at the point of direct contact; distance nullifies the force. Observe how quickly the load capacity drop, when the magnet does not touch directly to the metal substrate. When calculating the arrangement, discard unnecessary gaps.

The following data presents the estimated weight limit needed to start the shifting of the magnet downwards along a vertical metal surface (assuming typical friction). This parameter varies with the separation distance between the magnet and the metal.

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

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)

When hanging a element on a vertical plane (e.g., a fridge), it you can count on just about 1/5 of nominal attraction strength. Gravitational force and a low friction coefficient influence the fact that products move down easier than they detach. Want to create a wall mount? Note that the sliding force is significantly lower than the perpendicular breakaway force. On a smooth steel, the element will give way down under a significantly smaller load. Utilizing a rubberized layer can effectively increase the grip.

A thin metal plate is unable to absorb the entire magnetic field, which squanders power of the holder. If you mount a strong magnet to a too thin substrate, the field will pass right through and the holding will be smaller. To utilize the maximum of this magnet's power, you require a sufficiently solid element of steel. The saturation phenomenon means that on sheet metal structures (e.g., appliance housings), the holder shows lower pull force. We advise picking the steel thickness based on the following data.

Standard neodymium magnets change their properties power above the temperature limit. Watch out for overheating – high temperature can irreversibly demagnetize this magnet. With every degree above norm, the neodymium's force briefly lowers. Avoid using this product close to heaters exceeding its operating temperature limit. Too high temperature will cause permanent loss of magnetism.

*Engineering note: Heat tolerance depends not only on the material grade, and the Permeance Coefficient Pc. Thin magnets (low Pc) may lose charge permanently under lower heat stress than taller cylinders. Red status in the table points to permanent field degradation for this specific geometry.

Two magnetic products interact from a significantly greater distance than a magnet and sheet setup. The connection of two magnets produces a massive flux and a further horizon of action. Designing a powerful holder? Utilize two neodymiums instead of a neodymium and a striker plate. Remember that when attracting two neodymiums, the collision energy is extreme. The levitation is slightly lower than the connection force, but still significant.
*Field value in repulsion mode drops to ~0 Gs in the exact middle between the magnets (due to field cancellation).
Attention: Results apply to shear force of two matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

Powerful magnet radiation is a real danger to electronics as well as pacemakers. These neodymiums generate a field that disrupts operation of sensitive medical devices. Remember: the unseen radiation passes through tissues 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. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

NdFeB products are prone to chipping – a collision with steel risks their cracking. Watch the impact speed – a neodymium left loose turns into a projectile. Striking energy can cause material chips or injury to fingers. Be sure to control the product during mounting so it doesn't slam with momentum against the metal. A collision at high speed ends with a crack of the magnet. Wear safety glasses when working with powerful specimens.

Warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

The magnetic field penetrates through water without any losses. However, remember the water resistance when pulling the rope quickly.

1. Sliding resistance

*Warning: On a vertical wall, the magnet retains just approx. 20-30% of its nominal pull.

2. Steel thickness impact

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

3. Thermal stability

*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) = 0.26

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 a very powerful plate magnet made of NdFeB material, which, with dimensions of 40x10x4 mm and a weight of 12 g, guarantees premium class connection. As a block magnet with high power (approx. 9.31 kg), this product is available off-the-shelf from our warehouse in Poland. The durable anti-corrosion layer ensures a long lifespan in a dry environment, protecting the core from oxidation.

Separating strong flat magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. To separate the MPL 40x10x4x2[7/3.5] / 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.

They constitute a key element in the production of generators and material handling systems. They work great as invisible mounts under tiles, wood, or glass. Customers often choose this model for workshop organization on strips and for advanced DIY and modeling projects, where precision and power count.

For mounting flat magnets MPL 40x10x4x2[7/3.5] / N38, it is best to use 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. Avoid chemically aggressive glues or hot glue, which can demagnetize neodymium (above 80°C).

Standardly, the MPL 40x10x4x2[7/3.5] / N38 model is magnetized axially (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.

This model is characterized by dimensions 40x10x4 mm, which, at a weight of 12 g, makes it an element with high energy density. It is a magnetic block with dimensions 40x10x4 mm and a self-weight of 12 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Strengths as well as weaknesses of rare earth magnets.

Strengths

Besides their tremendous field intensity, neodymium magnets offer the following advantages:

They do not lose magnetism, even after nearly 10 years – the drop in lifting capacity is only ~1% (based on measurements),
They feature excellent resistance to weakening of magnetic properties when exposed to external fields,
By using a shiny layer of silver, the element acquires an elegant look,
Magnets are characterized by extremely high magnetic induction on the outer layer,
Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures reaching 230°C and above...
Thanks to freedom in constructing and the capacity to adapt to individual projects,
Huge importance in modern industrial fields – they serve a role in HDD drives, motor assemblies, precision medical tools, and complex engineering applications.
Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which makes them useful in compact constructions

Cons

Disadvantages of NdFeB magnets:

Brittleness is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a special holder, which not only secures them against impacts but also raises their durability
NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (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 rust. Therefore during using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
Due to limitations in realizing nuts and complicated forms in magnets, we recommend using a housing - magnetic holder.
Health risk related to microscopic parts of magnets are risky, if swallowed, which is particularly important in the context of child health protection. Additionally, small elements of these devices can disrupt the diagnostic process medical in case of swallowing.
With budget limitations the cost of neodymium magnets can be a barrier,

Lifting parameters

Maximum lifting capacity of the magnet – what affects it?

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

on a block made of mild steel, optimally conducting the magnetic field
possessing a thickness of at least 10 mm to avoid saturation
characterized by even structure
under conditions of no distance (metal-to-metal)
for force applied at a right angle (in the magnet axis)
at ambient temperature room level

Practical lifting capacity: influencing factors

Please note that the magnet holding will differ subject to elements below, in order of importance:

Distance (betwixt the magnet and the plate), since even a tiny clearance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
Load vector – highest force is reached only during pulling at a 90° angle. The shear force of the magnet along the plate is standardly several times smaller (approx. 1/5 of the lifting capacity).
Plate thickness – insufficiently thick steel does not close the flux, causing part of the flux to be wasted into the air.
Chemical composition of the base – mild steel attracts best. Alloy steels reduce magnetic properties and holding force.
Surface condition – smooth surfaces guarantee perfect abutment, which improves field saturation. Uneven metal reduce efficiency.
Thermal factor – hot environment weakens magnetic field. Too high temperature can permanently demagnetize the magnet.

Lifting capacity testing was conducted on a smooth plate of suitable thickness, under a perpendicular pulling force, however under parallel forces the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate decreases the holding force.

Safe handling of NdFeB magnets

Implant safety

Medical warning: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.

Do not underestimate power

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

Maximum temperature

Avoid heat. NdFeB magnets are sensitive to heat. If you require operation above 80°C, ask us about HT versions (H, SH, UH).

Bone fractures

Large magnets can smash fingers instantly. Do not place your hand between two attracting surfaces.

Beware of splinters

Despite the nickel coating, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.

Sensitization to coating

Medical facts indicate that nickel (the usual finish) is a common allergen. For allergy sufferers, avoid touching magnets with bare hands or opt for coated magnets.

No play value

Product intended for adults. Tiny parts pose a choking risk, leading to severe trauma. Keep out of reach of children and animals.

GPS and phone interference
