Grip strength weakens significantly with every subsequent millimeter of gap. Note that even a microscopic distance (e.g., contamination, paint, veneer) significantly diminishes the holding power. Magnets work most effectively in perfect adhesion; distance weakens the power. Analyze how quickly the pull force fall, when the magnet does not touch tightly to the metal substrate. When calculating the arrangement, discard additional spacers.

The following data shows the approximate weight limit required to initiate the shifting of the magnet downwards along a upright steel plate (considering typical friction coefficient). This value varies with the air gap between the magnet and the metal.

Table 3: Vertical assembly (shearing) - vertical pull
MP 22x6x10 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	4.10 kg / 9.03 LBS 4095.0 g / 40.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	2.73 kg / 6.02 LBS 2730.0 g / 26.8 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	1.37 kg / 3.01 LBS 1365.0 g / 13.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	6.83 kg / 15.05 LBS 6825.0 g / 67.0 N

When hanging a element on a vertical surface (e.g., a board), it will maintain just approx. 1/5 of its nominal power. Gravitational force and a weak degree of grip mean that products slip faster than they pull off. Planning a vertical fastening? Consider that the sliding force is noticeably lower than the perpendicular breakaway force. On a smooth steel, the magnet will slide down under a significantly smaller weight. Utilizing a rubberized pad can significantly improve the result.

A thin sheet is unable to take in the entire magnetic field, which wastes potential of the magnet. If you install a neodymium to a too thin substrate, the flux will pass right through and the pull force will drop sharply. To squeeze the maximum of this neodymium's potential, you require a sufficiently solid element of metal. The material oversaturation means that on thin elements (e.g., thin profiles), the magnet shows lower pull force. We advise picking the steel thickness based on the following data.

Classic neodymiums irreversibly lose strength past the thermal threshold. Watch out for overheating – heat can irreversibly damage this magnet. As the temperature rises, the magnet's capacity temporarily lowers. Do not use this magnet close to ovens higher than its working range. Exceeding the critical threshold will lead to destruction of magnetism.

*Technical advisory: Thermal stability depends not only on the material grade, and the Permeance Coefficient Pc. Thin magnets (low permeance coefficient) risk losing magnetic properties under lower heat stress than taller cylinders. The danger warning in the table points to permanent field degradation for this specific geometry.

Two magnets interact from a significantly greater distance than a magnet and steel setup. The setup of magnet-to-magnet creates a more powerful interaction and a larger range of performance. Designing a powerful holder? Apply two magnets instead of one magnet and a steel. Remember that when connecting a pair of magnets, the pinch force is extreme. The repulsion force is a bit weaker than the connection force, but still large.
*Flux density for N-N configuration is approximately ~0 Gs in the exact middle between the magnets (due to field cancellation).
Important: Calculations apply to sliding force of two identical magnets (friction coefficient ~0.15 for Ni-Ni plating).

Powerful magnet radiation is a serious hazard to electronic devices as well as pacemakers. These NdFeB products produce a flux that destroys function of digital equipment. Be aware: the invisible magnetic field passes through tissues and glass. Increased vigilance must be taken by people with cochlear implants and drug dispensers. Influence will be felt by: mechanical watches, remotes, speakers, and displays. Do not bring the product near payment cards, hard drives, or sensitive navigation tools.

Neodymium magnets are very brittle – a strong collision with metal can result in shattering. Control the attraction moment – a neodymium left loose becomes dangerous. Striking energy can trigger coating fragments or painful pinches to skin. Hold the magnet firmly during mounting so it doesn't hit with great force against the steel surface. A collision at high speed means shattering of the neodymium. Wear eye protection when working with powerful specimens.

Rust risk: 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. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Shear force

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

2. Plate thickness effect

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

3. Power loss vs temp

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 1.13

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 magnet with a hole MP 22x6x10 / N38 is created for mechanical fastening, where glue might fail or be insufficient. Mounting is clean and reversible, unlike gluing. This product with a force of 13.65 kg works great as a door latch, 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 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 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 6 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 (22 mm), so it doesn't protrude beyond the outline.

This model is characterized by dimensions Ø22x10 mm and a weight of 26.39 g. The key parameter here is the lifting capacity amounting to approximately 13.65 kg (force ~133.89 N). 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. When ordering a larger quantity, magnets are usually packed in stacks, where they are already naturally paired.

Strengths and weaknesses of rare earth magnets.

Benefits

Apart from their notable magnetic energy, neodymium magnets have these key benefits:

They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (according to literature),
Magnets effectively protect themselves against demagnetization caused by foreign field sources,
In other words, due to the aesthetic finish of gold, the element gains a professional look,
Magnets exhibit impressive magnetic induction on the surface,
Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures approaching 230°C and above...
Thanks to versatility in shaping and the ability to adapt to specific needs,
Significant place in advanced technology sectors – they are used in mass storage devices, electric drive systems, medical equipment, and industrial machines.
Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,

Cons

Cons of neodymium magnets and ways of using them

At very strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
When exposed to high temperature, neodymium magnets suffer a drop in force. 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
Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
We recommend cover - magnetic holder, due to difficulties in realizing threads inside the magnet and complex forms.
Potential hazard related to microscopic parts of magnets pose a threat, when accidentally swallowed, which becomes key in the context of child safety. Furthermore, small elements of these devices are able to complicate diagnosis medical after entering the body.
Due to expensive raw materials, their price is relatively high,

Lifting parameters

Magnetic strength at its maximum – what contributes to it?

The specified lifting capacity concerns the maximum value, recorded under optimal environment, namely:

with the application of a yoke made of low-carbon steel, ensuring full magnetic saturation
possessing a thickness of min. 10 mm to avoid saturation
with an polished touching surface
with direct contact (without coatings)
during detachment in a direction vertical to the plane
at standard ambient temperature

Determinants of lifting force in real conditions

It is worth knowing that the magnet holding will differ depending on the following factors, starting with the most relevant:

Distance – existence of foreign body (paint, dirt, gap) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
Angle of force application – maximum parameter is reached only during perpendicular pulling. The resistance to sliding of the magnet along the surface is usually many times smaller (approx. 1/5 of the lifting capacity).
Element thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
Steel type – mild steel attracts best. Alloy steels lower magnetic properties and holding force.
Plate texture – ground elements guarantee perfect abutment, which improves force. Uneven metal reduce efficiency.
Heat – NdFeB sinters 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).

Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under perpendicular forces, however under shearing force the holding force is lower. Moreover, even a slight gap between the magnet’s surface and the plate reduces the holding force.

Safe handling of neodymium magnets

Bone fractures

Large magnets can crush fingers instantly. Never place your hand between two strong magnets.

Metal Allergy

Some people suffer from a contact allergy to Ni, which is the typical protective layer for neodymium magnets. Prolonged contact might lead to dermatitis. We suggest wear protective gloves.

Heat sensitivity

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

Electronic devices

Avoid bringing magnets close to a wallet, computer, or TV. The magnetism can irreversibly ruin these devices and erase data from cards.

Eye protection

Watch out for shards. Magnets can explode upon uncontrolled impact, ejecting shards into the air. We recommend safety glasses.

Life threat

Medical warning: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.

Precision electronics

Remember: neodymium magnets produce a field that interferes with precision electronics. Maintain a separation from your mobile, tablet, and GPS.

Flammability

Drilling and cutting of neodymium magnets carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.

Swallowing risk

These products are not toys. Accidental ingestion of multiple magnets may result in them pinching intestinal walls, which constitutes a severe health hazard and necessitates immediate surgery.

Powerful field

Before starting, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.

Attention! Learn more about risks in the article: Magnet Safety Guide.
