Grip strength decreases significantly per each millimeter of spacing. Remember that even a very thin break (e.g., dirt, paint, rust) noticeably reduces the pull force. Magnets hold strongest at the point of direct contact; distance kills the power. Analyze how rapidly the parameters drop, when the magnet does not adhere directly to the metal substrate. When calculating the assembly, eliminate additional spacers.

When hanging a element on a upright wall (e.g., a car body), it will only hold only approx. 20%-30% of its maximum pull force. Gravitational force and a weak degree of grip influence the fact that products move down easier than they pull off. Designing a hanger? Consider that the sliding force is noticeably lower than the maximum static pull force. On a slippery surface, the magnet will slide down under a noticeably lighter weight. Utilizing a rubberized coating can drastically improve the result.

A thin metal plate is incapable of focus the entire magnetic field, which squanders power of the holder. Should you install a neodymium to a too thin substrate, the flux will pass right through and the attraction force will be weaker. To achieve full efficiency of this magnet's potential, you need a suitably thick piece of metal. The saturation effect means that on delicate walls (e.g., thin profiles), the magnet holds weaker. We advise picking the steel thickness from these parameters.

Standard neodymium magnets lose power after exceeding the maximum temperature. Protect against heat – high temperature can irreversibly destroy this magnet. With every degree above norm, the magnet's force briefly decreases. Refrain from using this product close to heaters higher than its operating temperature limit. Exceeding the critical threshold will cause irreversible degradation of magnetic properties.
*Technical advisory: Thermal stability is determined by both grade, as well as the dimension ratios. Low-profile magnets (low permeance coefficient) may lose charge permanently sooner than taller cylinders. The danger warning in the table points to permanent field degradation for this specific geometry.

Two magnetic products attract each other from a significantly greater distance than a magnet and steel setup. The connection of magnet-to-magnet produces a massive flux and a wider radius of operation. Planning to create a powerful holder? Utilize two neodymiums instead of one magnet and a striker plate. Be careful that when attracting two neodymiums, the pinch force is massive. The levitation is marginally weaker than the connection force, but still large.
*Flux density in repulsion mode drops to ~0 Gs at the midpoint of the gap (due to field cancellation).
Important: Results apply to friction force of dual matching magnets (friction coefficient ~0.15 for Ni-Ni plating).

Powerful magnet radiation is a real danger to IT equipment as well as pacemakers. These NdFeB products produce a field that disrupts operation of sensitive medical devices. Remember: the invisible magnetic field acts through matter and housings. Increased vigilance must be exercised by people with cochlear implants and insulin pumps. The risk also applies to: mechanical watches, car keys, membranes, and screens. Do not bring the product near payment cards, hard drives, or sensitive navigation tools.

NdFeB products are very brittle – a collision with steel causes immediate chipping. Pay attention to connection velocity – a magnet released freely speeds with massive force. Impact energy can cause material chips or painful pinches to fingers. Hold the magnet firmly during installation so it doesn't slam with momentum against the metal. A collision at high speed means shattering of the neodymium. Use safety goggles 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!
In water, the magnet feels stronger thanks to Archimedes' principle. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.
1. Wall mount (shear)

*Note: On a vertical wall, the magnet holds only ~20% of its perpendicular strength.

2. Steel saturation

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

3. Heat tolerance

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

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.37

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 Pc (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 Pc 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 magnet with a hole MP 10x7/3.5x3 / N38 is created for permanent mounting, where glue might fail or be insufficient. Mounting is clean and reversible, unlike gluing. This product with a force of 1.88 kg works great as a cabinet closure, speaker holder, or mounting element in devices.
This material behaves more like porcelain than steel, so it doesn't forgive mistakes during mounting. When tightening the screw, you must maintain caution. We recommend tightening manually with a screwdriver, not an impact driver, because excessive force 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.
Moisture can penetrate micro-cracks in the coating and cause oxidation of the magnet. Damage to the protective layer during assembly is the most common cause of rusting. This product is dedicated for inside building use. For outdoor applications, we recommend choosing magnets in hermetic housing or additional protection with varnish.
The inner hole diameter determines the maximum size of the mounting element. 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. Aesthetic mounting requires selecting the appropriate head size.
It is a magnetic ring with a diameter of 10 mm and thickness 3 mm. The pulling force of this model is an impressive 1.88 kg, which translates to 18.47 N in newtons. The mounting hole diameter is precisely 7/3.5 mm.
The poles are located on the planes with holes, not on the sides of the ring. 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.

Strengths as well as weaknesses of rare earth magnets.

Advantages

Besides their stability, neodymium magnets are valued for these benefits:
  • They do not lose power, even over approximately 10 years – the drop in lifting capacity is only ~1% (theoretically),
  • They maintain their magnetic properties even under close interference source,
  • Thanks to the elegant finish, the layer of Ni-Cu-Ni, gold-plated, or silver-plated gives an aesthetic appearance,
  • Magnets exhibit exceptionally strong magnetic induction on the outer side,
  • Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
  • Possibility of individual forming as well as optimizing to atypical conditions,
  • Wide application in modern industrial fields – they are commonly used in data components, motor assemblies, precision medical tools, also modern systems.
  • Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which makes them useful in miniature devices

Disadvantages

Problematic aspects of neodymium magnets and ways of using them
  • At strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
  • Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
  • Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
  • We recommend casing - magnetic holder, due to difficulties in creating nuts inside the magnet and complicated forms.
  • Possible danger to health – tiny shards of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child safety. It is also worth noting that tiny parts of these products are able to be problematic in diagnostics medical after entering the body.
  • High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities

Holding force characteristics

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

The force parameter is a theoretical maximum value performed under the following configuration:
  • with the contact of a yoke made of special test steel, ensuring maximum field concentration
  • with a cross-section no less than 10 mm
  • with a plane perfectly flat
  • without the slightest air gap between the magnet and steel
  • during pulling in a direction vertical to the mounting surface
  • at conditions approx. 20°C

Practical lifting capacity: influencing factors

Holding efficiency impacted by specific conditions, such as (from most important):
  • Distance (betwixt the magnet and the plate), since even a tiny distance (e.g. 0.5 mm) results in a reduction in force by up to 50% (this also applies to paint, corrosion or dirt).
  • 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.
  • Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
  • Steel type – low-carbon steel attracts best. Higher carbon content lower magnetic permeability and lifting capacity.
  • Surface finish – full contact is obtained only on polished steel. Rough texture reduce the real contact area, reducing force.
  • Heat – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).

Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under shearing force the lifting capacity is smaller. In addition, even a small distance between the magnet and the plate lowers the lifting capacity.

Safe handling of neodymium magnets
Beware of splinters

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

Pinching danger

Large magnets can smash fingers in a fraction of a second. Under no circumstances place your hand betwixt two strong magnets.

GPS Danger

A strong magnetic field disrupts the functioning of compasses in smartphones and GPS navigation. Maintain magnets near a smartphone to prevent damaging the sensors.

Medical implants

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

Dust is flammable

Powder created during machining of magnets is flammable. Do not drill into magnets unless you are an expert.

Operating temperature

Keep cool. Neodymium magnets are susceptible to temperature. If you need operation above 80°C, ask us about HT versions (H, SH, UH).

Powerful field

Exercise caution. Rare earth magnets act from a long distance and snap with huge force, often quicker than you can move away.

Allergic reactions
