Pulling power decreases significantly per each millimeter of distance. Remember that even the smallest gap (e.g., dirt, paint, dust) noticeably weakens the grip. Neodymiums operate most effectively in perfect adhesion; gap weakens the force. See how rapidly the pull force fall, when the magnet does not touch flatly to the steel surface. When planning the assembly, avoid unnecessary gaps.

The table below calculates the theoretical weight limit required to cause the shifting of the magnet downwards against a vertical steel plate (considering standard friction). This value is a function of the gap size between the magnet and the metal.

Table 3: Wall mounting (sliding) - vertical pull
MP 20x8x6 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	2.17 kg / 4.78 lbs 2166.0 g / 21.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.44 kg / 3.18 lbs 1444.0 g / 14.2 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.72 kg / 1.59 lbs 722.0 g / 7.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	3.61 kg / 7.96 lbs 3610.0 g / 35.4 N

When placing a holder on a upright plane (e.g., a board), it will maintain just approx. 20%-30% of its nominal power. Gravitational force and a low friction coefficient mean that products move down easier than they detach. Planning a vertical fastening? Remember that the sliding force is noticeably lower than the maximum static pull force. On a smooth steel, the element will slide down under a significantly smaller load. Application of an anti-slip pad can drastically raise the stability.

A thin metal plate is unable to focus the entire magnetic field, which squanders power of the holder. If you mount a strong magnet to a thin surface, the magnetism will pass right through and the pull force will drop sharply. To squeeze full efficiency of this neodymium's power, you require a sufficiently solid backing of steel. The saturation phenomenon causes that on thin elements (e.g., appliance housings), the holder holds weaker. We recommend selecting the steel dimension based on the following data.

Standard neodymium magnets irreversibly lose power after exceeding the maximum temperature. Avoid high temperatures – excessive heat can irreversibly destroy this magnet. As the temperature rises, the magnet's power temporarily drops. Refrain from using this product close to heaters higher than its safe range. Exceeding the critical threshold will lead to irreversible degradation of magnetic properties.

*Important note: Temperature resistance is determined by both grade, as well as the dimension ratios. Thin magnets (pancake types) risk losing magnetic properties at lower temperatures than taller cylinders. Red status in the table signals a risk of irreversible loss for this particular item.

Two strong neodymiums attract each other from a significantly greater distance than a magnet and sheet combination. The connection of two magnets produces a massive flux and a further horizon of operation. Want to build a solid fastener? Apply two magnets instead of a neodymium and a striker plate. Exercise caution that when connecting a pair of magnets, the impact force is huge. The levitation is slightly lower than the attraction, but still large.
*Flux density in repulsion mode reaches ~0 Gs at the midpoint between the magnets (resulting from vector opposition).
* Figures refer to friction force of two matching magnets (friction ~0.15 for Ni-Ni plating).

Extremely neodym field poses a large risk to electronic devices as well as medical implants. These NdFeB products produce a field that prevents correct functioning of sensitive medical devices. Notice: the invisible magnetic field passes through tissues and glass. Increased vigilance must be taken by people with cochlear implants and drug dispensers. Also at risk are: mechanical watches, remotes, membranes, and screens. Do not bring the product near payment cards, hard drives, or sensitive navigation tools.

Table 8: Impact energy (cracking risk) - warning
MP 20x8x6 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	26.04 km/h (7.23 m/s)	0.31 J
30 mm	43.11 km/h (11.97 m/s)	0.85 J
50 mm	55.60 km/h (15.44 m/s)	1.42 J
100 mm	78.62 km/h (21.84 m/s)	2.83 J

Neodymium magnets are very brittle – a collision with steel causes immediate chipping. Watch the impact speed – a neodymium left loose turns into a projectile. Impact energy can cause material chips or dangerous crushing to fingers. Hold the magnet firmly during bringing near metal so it doesn't hit with great force against the steel surface. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Wear safety glasses when working with powerful specimens.

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

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. Vertical hold

*Warning: On a vertical surface, the magnet holds only a fraction of its nominal pull.

2. Steel saturation

*Thin steel (e.g. computer case) severely weakens the holding force.

3. Power loss vs temp

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

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

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

The chart above illustrates the magnetic characteristics of the material within the second quadrant of the hysteresis loop. 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. It is also often used in advertising for fixing signs and in workshops for organizing tools.

This is a crucial issue when working with model MP 20x8x6 / N38. Neodymium magnets are sintered ceramics, which means they are very brittle and inelastic. One turn too many can destroy the magnet, so do it slowly. It's a good idea to use a rubber spacer 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. Damage to the protective layer during assembly is the most common cause of rusting. If you must use it outside, paint it with anti-corrosion paint after mounting.

A screw or bolt with a thread diameter smaller than 8 mm fits this model. For magnets with a straight hole, a conical head can act like a wedge and burst the magnet. 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.

The presented product is a ring magnet with dimensions Ø20 mm (outer diameter) and height 6 mm. The key parameter here is the holding force 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). 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 Nd₂Fe₁₄B magnets.

Advantages

In addition to their magnetic capacity, neodymium magnets provide the following advantages:

They virtually do not lose power, because even after ten years the performance loss is only ~1% (in laboratory conditions),
They show high resistance to demagnetization induced by external disturbances,
By using a reflective layer of silver, the element presents an modern look,
Neodymium magnets create maximum magnetic induction on a small area, which increases force concentration,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
Thanks to flexibility in forming and the capacity to modify to unusual requirements,
Versatile presence in advanced technology sectors – they are utilized in hard drives, drive modules, medical equipment, as well as other advanced devices.
Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which makes them useful in small systems

Cons

Disadvantages of NdFeB magnets:

To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
Limited ability of making threads in the magnet and complicated forms - recommended is a housing - magnet mounting.
Possible danger 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 are able to complicate diagnosis medical after entering the body.
Due to expensive raw materials, their price exceeds standard values,

Lifting parameters

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

Magnet power was defined for ideal contact conditions, taking into account:

with the use of a yoke made of special test steel, guaranteeing maximum field concentration
whose transverse dimension equals approx. 10 mm
characterized by lack of roughness
without any air gap between the magnet and steel
under axial force direction (90-degree angle)
in neutral thermal conditions

Lifting capacity in practice – influencing factors

Please note that the working load may be lower subject to the following factors, in order of importance:

Distance (between the magnet and the plate), as even a tiny distance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to varnish, corrosion or debris).
Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
Plate material – low-carbon steel gives the best results. Higher carbon content decrease magnetic properties and lifting capacity.
Surface quality – the more even the surface, the better the adhesion and stronger the hold. Roughness acts like micro-gaps.
Temperature – temperature increase causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.

Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, however under parallel forces the load capacity is reduced by as much as fivefold. In addition, even a slight gap between the magnet and the plate lowers the load capacity.

Safety rules for work with NdFeB magnets

Serious injuries

Protect your hands. Two large magnets will snap together immediately with a force of massive weight, destroying everything in their path. Exercise extreme caution!

Electronic devices

Very strong magnetic fields can erase data on credit cards, HDDs, and storage devices. Maintain a gap of at least 10 cm.

Fire risk

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

Do not overheat magnets

Control the heat. Heating the magnet to high heat will ruin its magnetic structure and strength.

Eye protection

Despite metallic appearance, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.

Danger to the youngest

Product intended for adults. Small elements pose a choking risk, causing serious injuries. Keep out of reach of kids and pets.

ICD Warning

For implant holders: Powerful magnets affect medical devices. Maintain at least 30 cm distance or request help to handle the magnets.

Allergic reactions

Certain individuals have a hypersensitivity to Ni, which is the standard coating for NdFeB magnets. Prolonged contact can result in skin redness. We recommend wear safety gloves.

Handling guide

Before starting, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.

Phone sensors

GPS units and mobile phones are extremely sensitive to magnetic fields. Direct contact with a powerful NdFeB magnet can permanently damage the sensors in your phone.

Caution! More info about risks in the article: Safety of working with magnets.
