Magnetic force weakens significantly with every subsequent millimeter of distance. Remember that even a very thin break (e.g., contamination, varnish, veneer) strongly reduces the pull force. Magnets operate most effectively at the point of direct contact; gap kills the power. Observe how flashily the load capacity drop, when the product does not adhere directly to the metal substrate. When calculating the assembly, avoid redundant distances.

The following data shows the estimated shear load required to cause the shifting of the magnet downwards against a vertical steel plate (considering typical friction). This parameter is a function of the separation distance between the magnet and the surface.

Table 3: Wall mounting (sliding) - vertical pull

When hanging a holder on a vertical plane (e.g., a board), it will maintain only about 20%-30% of its maximum pull force. Gravity as well as a low friction coefficient influence the fact that products slip faster than they pop off the substrate. Planning a wall mount? Remember that the sliding force is significantly lower than the maximum static pull force. On a slippery surface, the element will give way down under a significantly smaller load. Application of an anti-slip coating can drastically increase the grip.

A thin sheet cannot focus the entire magnetic field, which weakens actual performance of the holder. Should you mount a strong magnet to a thin surface, the magnetism will pass right through and the holding will be smaller. To achieve 100% of this magnet's potential, you need a suitably thick piece of steel. The material oversaturation causes that on thin elements (e.g., car bodies), the holder works worse. We suggest choosing the steel dimension based on the following data.

Standard neodymium magnets lose parameters past the thermal threshold. Watch out for overheating – heat can irreversibly damage this product. With every degree above norm, the magnet's force temporarily decreases. Refrain from using this magnet close to heaters higher than its working range. Exceeding the critical threshold will lead to destruction of magnetism.

*Important note: Temperature resistance depends not only on the material grade, as well as the dimension ratios. Low-profile magnets (low Pc) are more susceptible to demagnetization under lower heat stress than long magnets. Warning indicator in the table points to permanent field degradation for this particular item.

Two magnets interact from a wider radius than a magnet and sheet setup. The connection of two magnets produces a massive flux and a wider radius of performance. Designing a powerful holder? Use a pair of magnets instead of a neodymium and a striker plate. Exercise caution that when attracting two neodymiums, the collision energy is extreme. The levitation is a bit weaker than the attraction, but still large.
*Flux density between like poles is approximately ~0 Gs at the midpoint between the magnets (resulting from vector opposition).
Attention: Figures demonstrate friction force of two same magnets (friction coefficient ~0.15 for Ni-Ni coating).

Powerful magnet radiation is a serious hazard to IT equipment and medical implants. These NdFeB products generate a flux that prevents correct functioning of sensitive medical devices. Notice: the invisible magnetic field passes through tissues and housings. Increased vigilance must be taken by people with hearing aids and insulin pumps. The risk also applies to: automatic timepieces, car keys, speakers, and displays. Avoid contact with magnetic cards, HDD media, or sensitive navigation tools.

Neodymium magnets are delicate – a violent impact against metal causes immediate chipping. Pay attention to connection velocity – a magnet released freely speeds with massive force. Kinetic force can destroy the magnet or injury to skin. Hold the magnet firmly during installation so it doesn't hit violently against the steel surface. A collision at high speed means shattering of the neodymium. Wear safety glasses when handling 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!

Water displaces steel, making heavy objects slightly lighter. Buoyancy helps in lifting finds.

1. Wall mount (shear)

*Warning: On a vertical surface, the magnet retains merely approx. 20-30% of its max power.

2. Plate thickness effect

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

3. Thermal stability

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.96

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.

It is ideally suited for places where solid attachment of the magnet to the substrate is required without the risk of detachment. Mounting is clean and reversible, unlike gluing. This product with a force of 20.71 kg works great as a door latch, speaker holder, or spacer element in devices.

This is a crucial issue when working with model MP 30x6x10 / N38. Neodymium magnets are sintered ceramics, which means they are very brittle and inelastic. When tightening the screw, you must maintain great sensitivity. We recommend tightening manually with a screwdriver, not an impact driver, because too much pressure will cause the ring to crack. It's a good idea to use a flexible washer under the screw head, which will cushion the stresses. 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 does not ensure full waterproofing. In the place of the mounting hole, the coating is thinner and easily scratched when tightening the screw, which will become a corrosion focus. If you must use it outside, paint it with anti-corrosion paint after mounting.

The inner hole diameter determines the maximum size of the mounting element. For magnets with a straight hole, a conical head can act like a wedge and burst the magnet. Aesthetic mounting requires selecting the appropriate head size.

It is a magnetic ring with a diameter of 30 mm and thickness 10 mm. The pulling force of this model is an impressive 20.71 kg, which translates to 203.16 N in newtons. The product has a [NiCuNi] coating and is made of NdFeB material. Inner hole dimension: 6 mm.

These magnets are magnetized axially (through the thickness), which means one flat side is the N pole and the other is S. In the case of connecting two rings, make sure one is turned the right way. We do not offer paired sets with marked poles in this category, but they are easy to match manually.

Advantages and disadvantages of rare earth magnets.

Strengths

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

They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (in laboratory conditions),
They do not lose their magnetic properties even under close interference source,
In other words, due to the reflective finish of nickel, the element is aesthetically pleasing,
Magnetic induction on the working part of the magnet turns out to be maximum,
Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures reaching 230°C and above...
Thanks to modularity in forming and the capacity to customize to client solutions,
Wide application in modern technologies – they serve a role in mass storage devices, brushless drives, medical devices, as well as other advanced devices.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Limitations

Disadvantages of neodymium magnets:

To avoid cracks under impact, we recommend using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
Neodymium magnets decrease their force 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 - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
Limited possibility of producing nuts in the magnet and complicated shapes - preferred is a housing - magnet mounting.
Potential hazard resulting from small fragments of magnets are risky, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that tiny parts of these products can disrupt the diagnostic process medical in case of swallowing.
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

Maximum lifting capacity of the magnet – what contributes to it?

Holding force of 20.71 kg is a measurement result performed under standard conditions:

with the application of a yoke made of special test steel, ensuring full magnetic saturation
whose transverse dimension is min. 10 mm
with a surface perfectly flat
with total lack of distance (no impurities)
for force applied at a right angle (pull-off, not shear)
at room temperature

Magnet lifting force in use – key factors

Bear in mind that the working load will differ subject to the following factors, starting with the most relevant:

Air gap (between the magnet and the metal), because even a very small distance (e.g. 0.5 mm) can cause a drastic drop in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
Force direction – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet exhibits much less (typically approx. 20-30% of maximum force).
Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
Plate material – mild steel attracts best. Alloy steels lower magnetic permeability and holding force.
Surface condition – smooth surfaces guarantee perfect abutment, which improves field saturation. Rough surfaces weaken the grip.
Operating temperature – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and at low temperatures they can be stronger (up to a certain limit).

Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the holding force.

Safe handling of neodymium magnets

Danger to the youngest

Only for adults. Tiny parts pose a choking risk, leading to severe trauma. Store away from kids and pets.

Dust is flammable

Powder produced during cutting of magnets is combustible. Do not drill into magnets unless you are an expert.

Electronic devices

Avoid bringing magnets near a wallet, laptop, or screen. The magnetism can destroy these devices and erase data from cards.

Sensitization to coating

Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If redness appears, immediately stop handling magnets and use protective gear.

Conscious usage

Exercise caution. Neodymium magnets act from a long distance and connect with massive power, often quicker than you can react.

Hand protection

Protect your hands. Two powerful magnets will join instantly with a force of massive weight, destroying everything in their path. Be careful!

Do not overheat magnets

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

Medical implants

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

GPS and phone interference

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

Material brittleness

NdFeB magnets are ceramic materials, meaning they are very brittle. Impact of two magnets will cause them breaking into small pieces.
