Magnetic force decreases drastically per each millimeter of gap. Remember that even a microscopic distance (e.g., dirt, varnish, dust) significantly reduces the pull force. Neodymiums hold most effectively during direct contact; gap kills the power. Observe how flashily the parameters plummet, when the magnet does not adhere tightly to the metal substrate. When calculating the assembly, discard redundant distances.

This section presents the estimated force required to start the slippage of the magnet vertically along a vertical steel wall (considering standard friction). This value depends on the air gap between the magnet and the metal.

When placing a element on a vertical wall (e.g., a board), it will only hold only about 1/5 of its nominal power. Gravity as well as a weak degree of grip mean that holders slide down easier than they detach. Designing a hanger? Consider that the sliding force is noticeably lower than the maximum static pull force. On a smooth steel, the holder will slip down under a significantly smaller load. Application of an anti-slip coating can significantly raise the stability.

A thin sheet cannot conduct the entire magnetic field, which weakens actual performance of the magnet. Should you mount a strong magnet to a thin surface, the flux will penetrate right through and the attraction force will be weaker. To utilize 100% of this magnet's power, you need a suitably thick backing of steel. The saturation effect means that on thin elements (e.g., car bodies), the holder shows lower pull force. We suggest choosing the steel dimension based on the following data.

Standard neodymium magnets change their properties power after exceeding the maximum temperature. Protect against heat – high temperature can irreversibly demagnetize this magnet. With every degree above norm, the neodymium's force momentarily decreases. Refrain from using this magnet close to ovens exceeding its operating temperature limit. Too high temperature will cause destruction of magnetism.

*Important note: Temperature resistance depends not only on the material grade, as well as the dimension ratios. Low-profile magnets (low permeance coefficient) are more susceptible to demagnetization at lower temperatures compared to rod magnets. The danger warning in the table points to permanent field degradation for this particular item.

Two strong neodymiums attract each other from a significantly greater distance than a magnet and steel combination. The connection of magnet-to-magnet creates a more powerful interaction and a larger range of operation. Planning to create a solid fastener? Use a pair of magnets instead of one magnet and a steel. Be careful that when attracting two neodymiums, the impact force is extreme. The levitation is slightly lower than the attraction, but still significant.
*Flux density between like poles is approximately ~0 Gs in the exact middle between the magnets (caused by magnetic field nullification).
Important: Figures demonstrate sliding force of a pair of identical magnets (friction coefficient ~0.15 for Ni-Ni layer).

Extremely neodym field is a serious hazard to electronic devices and medical implants. These magnets generate a flux that prevents correct functioning of sensitive medical devices. Be aware: the unseen radiation passes through tissues and housings. Special caution must be taken by people with cochlear implants and drug dispensers. Also at risk are: mechanical watches, remotes, speakers, and displays. Do not place the magnet near cards, hard drives, or precise measuring instruments.

NdFeB products are prone to chipping – a violent impact against metal risks their cracking. Watch the impact speed – a neodymium left loose becomes dangerous. Striking energy can cause material chips or painful pinches to fingers. Always hold the magnet during mounting so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h almost guarantees destruction of the neodymium. Wear eye protection when playing with large magnets.

Warning: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

Contrary to myths, water does not block the magnetic field. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Shear force

*Note: On a vertical wall, the magnet retains only ~20% of its nominal pull.

2. Plate thickness effect

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

3. Heat tolerance

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 1.14

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.

The ring-shaped magnet MP 20x8x6 / N38 is created for mechanical fastening, where glue might fail or be insufficient. Thanks to the hole (often for a screw), this model enables easy screwing to wood, wall, plastic, or metal. It is also often used in advertising for fixing signs and in workshops for organizing tools.

This material behaves more like porcelain than steel, so it doesn't forgive mistakes during mounting. One turn too many can destroy the magnet, so do it slowly. The flat screw head should evenly press the magnet. Remember: cracking during assembly results from material properties, not a product defect.

These magnets are coated with standard Ni-Cu-Ni plating, which protects them in indoor conditions, but is not sufficient for rain. Damage to the protective layer during assembly is the most common cause of rusting. This product is dedicated for indoor use. For outdoor applications, we recommend choosing magnets in hermetic housing or additional protection with varnish.

A screw or bolt with a thread diameter smaller than 8 mm fits this model. If the magnet does not have a chamfer (cone), we recommend using a screw with a flat or cylindrical head, or possibly using a washer. Always check that the screw head is not larger than the outer diameter of the magnet (20 mm), so it doesn't protrude beyond the outline.

This model is characterized by dimensions Ø20x6 mm and a weight of 11.88 g. The key parameter here is the lifting capacity amounting to approximately 7.22 kg (force ~70.81 N). The mounting hole diameter is precisely 8 mm.

These magnets are magnetized axially (through the thickness), which means one flat side is the N pole and the other is S. If you want two such magnets screwed with cones facing each other (faces) to attract, you must connect them with opposite poles (N to S). When ordering a larger quantity, magnets are usually packed in stacks, where they are already naturally paired.

Advantages and disadvantages of neodymium magnets.

Strengths

Apart from their strong holding force, neodymium magnets have these key benefits:

They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (according to literature),
They maintain their magnetic properties even under close interference source,
A magnet with a shiny gold surface has better aesthetics,
Magnetic induction on the surface of the magnet remains extremely intense,
Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for functioning at temperatures approaching 230°C and above...
Thanks to modularity in constructing and the capacity to adapt to specific needs,
Universal use in advanced technology sectors – they serve a role in hard drives, electromotive mechanisms, medical devices, as well as complex engineering applications.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in compact constructions

Disadvantages

Disadvantages of NdFeB magnets:

To avoid cracks under impact, we suggest using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
Limited ability of creating nuts in the magnet and complex forms - recommended is cover - magnetic holder.
Health risk resulting from small fragments of magnets are risky, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, small components of these devices can be problematic in diagnostics medical after entering the body.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Holding force characteristics

Best holding force of the magnet in ideal parameters – what contributes to it?

Information about lifting capacity is the result of a measurement for the most favorable conditions, taking into account:

with the application of a yoke made of special test steel, guaranteeing maximum field concentration
whose transverse dimension is min. 10 mm
with an ground touching surface
under conditions of no distance (metal-to-metal)
during pulling in a direction vertical to the plane
at room temperature

Determinants of lifting force in real conditions

Please note that the working load will differ depending on elements below, starting with the most relevant:

Space between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by veneer or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
Loading method – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet exhibits much less (often approx. 20-30% of maximum force).
Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
Plate material – low-carbon steel attracts best. Higher carbon content reduce magnetic permeability and lifting capacity.
Smoothness – full contact is obtained only on smooth steel. Rough texture reduce the real contact area, reducing force.
Thermal conditions – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).

Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under shearing force the lifting capacity is smaller. In addition, even a slight gap between the magnet’s surface and the plate lowers the load capacity.

Warnings

Combustion hazard

Mechanical processing of NdFeB material poses a fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.

Magnets are brittle

Protect your eyes. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. We recommend safety glasses.

GPS and phone interference

Navigation devices and mobile phones are extremely susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can decalibrate the sensors in your phone.

Nickel allergy

Medical facts indicate that the nickel plating (standard magnet coating) is a common allergen. If you have an allergy, refrain from direct skin contact and opt for encased magnets.

Warning for heart patients

For implant holders: Powerful magnets affect electronics. Keep at least 30 cm distance or ask another person to handle the magnets.

Electronic hazard

Avoid bringing magnets close to a purse, computer, or TV. The magnetic field can permanently damage these devices and wipe information from cards.

Choking Hazard

Always store magnets out of reach of children. Ingestion danger is high, and the effects of magnets clamping inside the body are tragic.

Heat sensitivity

Regular neodymium magnets (grade N) lose magnetization when the temperature surpasses 80°C. This process is irreversible.

Bodily injuries

Large magnets can smash fingers instantly. Never put your hand betwixt two attracting surfaces.

Do not underestimate power

Handle magnets consciously. Their powerful strength can shock even professionals. Plan your moves and respect their force.

Danger! More info about hazards in the article: Magnet Safety Guide.
