Magnetic force drops drastically with every mm of distance. Note that even a microscopic distance (e.g., dirt, varnish, rust) strongly weakens the grip. Magnets work strongest at the point of direct contact; gap drastically cuts the power. Notice how rapidly the load capacity plummet, when the magnet does not adhere directly to the steel surface. When planning the assembly, eliminate unnecessary gaps.

This section indicates the approximate holding capacity needed to cause the sliding of the magnet downwards along a upright steel wall (considering typical friction coefficient). This value varies with the air gap between the magnet and the metal.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces
MP 62x42x25 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	17.60 kg / 38.80 pounds 17601.0 g / 172.7 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	11.73 kg / 25.87 pounds 11734.0 g / 115.1 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	5.87 kg / 12.93 pounds 5867.0 g / 57.6 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	29.34 kg / 64.67 pounds 29335.0 g / 287.8 N

When hanging a element on a upright surface (e.g., a fridge), it will maintain barely approx. 20%-30% of its maximum pull force. Gravitational force as well as a weak degree of grip mean that products slip faster than they detach. Planning a wall mount? Note that the shear force is much weaker than the maximum static pull force. On a slippery surface, the holder will slip down under a noticeably lighter cargo. Using a rubber pad can significantly raise the stability.

A thin metal plate is incapable of conduct the entire magnetic field, which weakens actual performance of the magnet. Should you mount a strong magnet to a weak sheet, the flux will penetrate 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 steel. The material oversaturation causes that on delicate walls (e.g., appliance housings), the magnet works worse. We recommend selecting the steel cross-section based on the following data.

Classic neodymiums lose power above the temperature limit. Watch out for overheating – high temperature can irreversibly destroy this magnet. With increasing heat, the magnet's force momentarily decreases. Avoid using this magnet close to ovens higher than its safe range. Too high temperature will result in irreversible degradation of magnetism.

*Engineering note: Thermal stability depends not only on the material grade, as well as the dimension ratios. Flat magnets (pancake types) risk losing magnetic properties at lower temperatures than long magnets. The danger warning in the table signals permanent field degradation for this specific geometry.

Two magnetic products interact from a wider radius than a magnet and sheet combination. The setup of magnet-to-magnet generates a stronger field and a larger range of operation. Want to build a strong closure? Utilize two neodymiums instead of one magnet and a steel. Remember that when attracting two neodymiums, the pinch force is extreme. The levitation is slightly lower than the attraction, but still impressive.
*The magnetic induction for N-N configuration drops to ~0 Gs in the exact middle of the gap (due to field cancellation).
Attention: Results demonstrate friction force of two matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

Table 7: Safety (HSE) (electronics) - warnings

Powerful magnet radiation poses a large risk to electronics and pacemakers. These magnets produce a flux that disrupts operation of digital equipment. Notice: the unseen radiation acts through matter and glass. Special caution must be exercised by people with cochlear implants and insulin pumps. Also at risk are: mechanical watches, car keys, membranes, and screens. Do not place the magnet near cards, HDD media, or precise measuring instruments.

Magnetic elements are very brittle – a violent impact against metal causes immediate chipping. Pay attention to connection velocity – a neodymium left loose turns into a projectile. Striking energy can cause material chips or injury to fingers. Be sure to control the product during mounting so it doesn't hit violently against the metal. A collision at high speed almost guarantees destruction of the neodymium. Use safety goggles when playing with powerful specimens.

Warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

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. Wall mount (shear)

*Note: On a vertical wall, the magnet holds merely approx. 20-30% of its max power.

2. Efficiency vs thickness

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

3. Thermal stability

*For standard magnets, the max working temp is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.64

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.

The ring-shaped magnet MP 62x42x25 / N38 is created for mechanical fastening, where glue might fail or be insufficient. Thanks to the hole (often for a screw), this model enables quick installation to wood, wall, plastic, or metal. This product with a force of 58.67 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 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 is not sufficient for rain. In the place of the mounting hole, the coating is thinner and can be damaged when tightening the screw, which will become a corrosion focus. 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 42 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. Aesthetic mounting requires selecting the appropriate head size.

It is a magnetic ring with a diameter of 62 mm and thickness 25 mm. The pulling force of this model is an impressive 58.67 kg, which translates to 575.60 N in newtons. The mounting hole diameter is precisely 42 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 and weaknesses of neodymium magnets.

Advantages

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

They retain full power for nearly 10 years – the loss is just ~1% (based on simulations),
They do not lose their magnetic properties even under close interference source,
Thanks to the shiny finish, the plating of Ni-Cu-Ni, gold-plated, or silver gives an professional appearance,
They show high magnetic induction at the operating surface, which affects their effectiveness,
Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
Possibility of custom creating and modifying to individual applications,
Key role in high-tech industry – they are used in magnetic memories, electric drive systems, diagnostic systems, also multitasking production systems.
Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,

Cons

What to avoid - cons of neodymium magnets: weaknesses and usage proposals

They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
Neodymium magnets decrease their force 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
Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
We recommend a housing - magnetic mechanism, due to difficulties in producing nuts inside the magnet and complex forms.
Possible danger related to microscopic parts of magnets can be dangerous, if swallowed, which gains importance in the context of child safety. Additionally, small elements of these products are able to disrupt the diagnostic process medical in case of swallowing.
With mass production the cost of neodymium magnets is a challenge,

Holding force characteristics

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

The lifting capacity listed is a theoretical maximum value conducted under the following configuration:

with the use of a sheet made of low-carbon steel, ensuring full magnetic saturation
with a cross-section minimum 10 mm
with an polished contact surface
with direct contact (no impurities)
during detachment in a direction vertical to the plane
at temperature room level

Key elements affecting lifting force

It is worth knowing that the working load may be lower influenced by elements below, in order of importance:

Clearance – the presence of foreign body (rust, dirt, air) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
Loading method – catalog parameter refers to pulling vertically. When attempting to slide, the magnet exhibits much less (typically approx. 20-30% of nominal force).
Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
Steel type – mild steel attracts best. Alloy admixtures reduce magnetic permeability and holding force.
Base smoothness – the smoother and more polished the plate, the better the adhesion and stronger the hold. Unevenness creates an air distance.
Thermal factor – hot environment reduces pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.

Lifting capacity was assessed using a polished steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 5 times. In addition, even a minimal clearance between the magnet and the plate decreases the lifting capacity.

Safety rules for work with neodymium magnets

Hand protection

Watch your fingers. Two large magnets will snap together instantly with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!

Protective goggles

Protect your eyes. Magnets can fracture upon violent connection, launching sharp fragments into the air. We recommend safety glasses.

Medical implants

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

Heat warning

Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will permanently weaken its properties and strength.

Threat to navigation

GPS units and smartphones are highly susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can permanently damage the sensors in your phone.

Do not give to children

Absolutely keep magnets away from children. Ingestion danger is significant, and the effects of magnets connecting inside the body are life-threatening.

Nickel coating and allergies

Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If redness happens, cease working with magnets and wear gloves.

Fire warning

Fire warning: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this risks ignition.

Cards and drives

Avoid bringing magnets near a wallet, computer, or TV. The magnetic field can irreversibly ruin these devices and wipe information from cards.

Respect the power

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

Safety First! More info about hazards in the article: Safety of working with magnets.
