Magnetic force weakens significantly with every subsequent millimeter of distance. Note that even a very thin break (e.g., dirt, paint, dust) significantly diminishes the holding power. Magnets work optimally in perfect adhesion; air break nullifies the force. Notice how quickly the load capacity drop, when the product does not adhere directly to the metal substrate. When planning the mounting, eliminate redundant distances.

The table below calculates the theoretical shear load sufficient to cause the slippage of the magnet vertically against a vertical steel wall (considering typical friction coefficient). The holding force is a function of the separation distance between the magnet and the metal.

When mounting a holder on a vertical plane (e.g., a fridge), it you can count on only approx. 20%-30% of its maximum pull force. Gravitational force and a weak degree of grip influence the fact that products slide down faster than they detach. Designing a hanger? Remember that the shear force is noticeably lower than the perpendicular breakaway force. On a painted metal, the holder will slip down under a much lighter weight. Using a rubber pad can significantly improve the result.

A thin metal plate is incapable of focus the full magnetic flux, which wastes potential of the holder. If you mount a strong magnet to a weak sheet, the flux will pass right through and the pull force will drop sharply. To achieve 100% of this neodymium's power, you need a suitably thick piece of steel. The material oversaturation causes that on delicate walls (e.g., appliance housings), the holder shows lower pull force. We recommend selecting the steel cross-section according to the table below.

Standard neodymium magnets irreversibly lose parameters past the thermal threshold. Watch out for overheating – high temperature can permanently destroy this product. With every degree above norm, the neodymium's force temporarily drops. Do not use this magnet close to ovens higher than its safe range. Ignoring the limit will result in irreversible degradation of magnetism.

*Important note: Thermal stability depends not only on the material grade, but also on the magnet's shape. Thin magnets (low Pc) are more susceptible to demagnetization at lower temperatures than long magnets. The danger warning in the table signals permanent field degradation for this specific geometry.

Two magnetic products attract each other from a much further 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 powerful holder? Use a pair of magnets instead of one magnet and a steel. Exercise caution that when bringing together two magnets, the pinch force is massive. The levitation is a bit weaker than the attraction, but still large.
*The magnetic induction for N-N configuration reaches ~0 Gs at the geometric center between the magnets (caused by magnetic field nullification).
Important: Calculations apply to friction force of dual matching neodymium magnets (friction ~0.15 for Ni-Ni layer).

A strong magnetic field is a serious hazard to electronic devices and pacemakers. These neodymiums produce a field that destroys function of sensitive medical devices. Notice: the invisible magnetic field penetrates the body and plastic. Exceptional care must be exercised by people with hearing aids and insulin pumps. Also at risk are: automatic timepieces, remotes, membranes, and screens. Do not place the magnet near cards, hard drives, or precise measuring instruments.

Neodymium magnets are prone to chipping – a strong collision with metal causes immediate chipping. Pay attention to connection velocity – a neodymium left loose turns into a projectile. Striking energy can trigger coating fragments or injury to skin. Always hold the magnet during installation so it doesn't slam with momentum against the metal. A collision at high speed ends with a crack of the neodymium. Wear eye protection when playing with large magnets.

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

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 surface, the magnet holds just approx. 20-30% of its nominal pull.

2. Steel thickness impact

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

3. Heat tolerance

*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) = 0.44

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 powerful cylindrical magnet, composed of advanced NdFeB material, which, with dimensions of Ø15x5 mm, guarantees optimal power. The MW 15x5 / N38 model boasts an accuracy of ±0.1mm and industrial build quality, making it an ideal solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 5.39 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring lightning-fast order fulfillment. Additionally, its Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

It finds application in DIY projects, advanced automation, and broadly understood industry, serving as a fastening or actuating element. Thanks to the high power of 52.83 N with a weight of only 6.63 g, this rod is indispensable in miniature devices and wherever low weight is crucial.

Since our magnets have a very precise dimensions, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 15.1 mm) using epoxy glues. To ensure stability in automation, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.

Grade N38 is the most popular standard for industrial neodymium magnets, offering an optimal price-to-power ratio and operational stability. If you need the strongest magnets in the same volume (Ø15x5), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.

This model is characterized by dimensions Ø15x5 mm, which, at a weight of 6.63 g, makes it an element with impressive magnetic energy density. The key parameter here is the holding force amounting to approximately 5.39 kg (force ~52.83 N), which, with such defined dimensions, proves the high grade of the NdFeB material. The product has a [NiCuNi] coating, which protects the surface against oxidation, giving it an aesthetic, silvery shine.

This cylinder is magnetized axially (along the height of 5 mm), which means that the N and S poles are located on the flat, circular surfaces. Such an arrangement is standard when connecting magnets in stacks (e.g., in filters) or when mounting in sockets at the bottom of a hole. On request, we can also produce versions magnetized through the diameter if your project requires it.

Strengths and weaknesses of rare earth magnets.

Advantages

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

Their magnetic field is durable, and after around 10 years it drops only by ~1% (theoretically),
They possess excellent resistance to weakening of magnetic properties due to opposing magnetic fields,
In other words, due to the metallic surface of silver, the element gains a professional look,
Neodymium magnets create maximum magnetic induction on a contact point, which ensures high operational effectiveness,
Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
In view of the possibility of free shaping and adaptation to custom needs, magnetic components can be produced in a broad palette of geometric configurations, which increases their versatility,
Fundamental importance in high-tech industry – they are utilized in HDD drives, electromotive mechanisms, medical devices, as well as industrial machines.
Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,

Limitations

Disadvantages of neodymium magnets:

They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
We suggest casing - magnetic mechanism, due to difficulties in realizing threads inside the magnet and complicated shapes.
Potential hazard to health – tiny shards of magnets can be dangerous, if swallowed, which gains importance in the context of child safety. Additionally, small elements of these devices are able to be problematic in diagnostics medical when they are in the body.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Holding force characteristics

Detachment force of the magnet in optimal conditions – what contributes to it?

Breakaway force was defined for the most favorable conditions, assuming:

using a sheet made of high-permeability steel, functioning as a magnetic yoke
with a cross-section of at least 10 mm
characterized by smoothness
without any insulating layer between the magnet and steel
for force acting at a right angle (pull-off, not shear)
at room temperature

Magnet lifting force in use – key factors

Bear in mind that the magnet holding will differ subject to the following factors, in order of importance:

Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
Loading method – catalog parameter refers to detachment vertically. When applying parallel force, the magnet holds much less (typically approx. 20-30% of nominal force).
Substrate thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
Chemical composition of the base – mild steel attracts best. Alloy admixtures lower magnetic properties and lifting capacity.
Surface quality – the more even the plate, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
Temperature – temperature increase results in weakening of induction. It is worth remembering the thermal limit for a given model.

Lifting capacity testing was carried out on a smooth plate of suitable thickness, under a perpendicular pulling force, however under parallel forces the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the load capacity.

Safety rules for work with NdFeB magnets

Danger to pacemakers

Medical warning: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.

Nickel allergy

Allergy Notice: The nickel-copper-nickel coating contains nickel. If redness appears, immediately stop working with magnets and wear gloves.

Phone sensors

An intense magnetic field disrupts the functioning of magnetometers in smartphones and navigation systems. Do not bring magnets near a smartphone to prevent damaging the sensors.

Crushing force

Big blocks can crush fingers in a fraction of a second. Under no circumstances put your hand betwixt two strong magnets.

Electronic devices

Very strong magnetic fields can erase data on credit cards, hard drives, and storage devices. Keep a distance of at least 10 cm.

This is not a toy

Strictly store magnets away from children. Choking hazard is high, and the consequences of magnets connecting inside the body are fatal.

Heat sensitivity

Standard neodymium magnets (grade N) undergo demagnetization when the temperature surpasses 80°C. Damage is permanent.

Handling rules

Handle magnets consciously. Their powerful strength can surprise even experienced users. Plan your moves and do not underestimate their power.

Dust is flammable

Powder generated during cutting of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.

Protective goggles

NdFeB magnets are sintered ceramics, which means they are prone to chipping. Clashing of two magnets will cause them shattering into shards.

Caution! Details about hazards in the article: Safety of working with magnets.
