Pulling power decreases sharply per each millimeter of spacing. Keep in mind that even a microscopic distance (e.g., dirt, paint, rust) strongly reduces the pull force. Magnetic products work optimally in perfect adhesion; distance kills the force. Analyze how quickly the pull force drop, when the product does not adhere directly to the metal substrate. When designing the arrangement, eliminate redundant distances.

The following data shows the approximate holding capacity sufficient to cause the downward movement of the magnet downwards on a upright metal surface (considering typical friction). This value is relative to the air gap between the magnet and the surface.

Raw steel	µ = 0.3 30% Nominalnej Siły	17.60 kg / 38.80 lbs 17601.0 g / 172.7 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	11.73 kg / 25.87 lbs 11734.0 g / 115.1 N

Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	29.34 kg / 64.67 lbs 29335.0 g / 287.8 N

When placing a element on a vertical plane (e.g., a board), it will maintain only approx. 1/5 of its nominal power. Gravity and a weak degree of grip mean that products move down easier than they pull off. Designing a hanger? Note that the sliding force is much weaker than the maximum static pull force. On a slippery surface, the holder will slide down under a significantly smaller weight. Using a rubber layer can drastically increase the grip.

12 mm	100%	58.67 kg / 129.35 lbs 58670.0 g / 575.6 N

A too thin steel is incapable of take in the full magnetic flux, which squanders power of the magnet. Should you mount a strong magnet to a thin surface, the flux will penetrate right through and the pull force will drop sharply. To achieve the maximum of this neodymium's potential, you need a suitably thick backing of metal. The saturation effect means that on delicate walls (e.g., thin profiles), the holder works worse. We recommend selecting the steel thickness from these parameters.

Classic neodymiums irreversibly lose power past the thermal threshold. Watch out for overheating – heat can irreversibly demagnetize this magnet. With every degree above norm, the magnet's force temporarily drops. Avoid using this magnet close to heaters exceeding its working range. Exceeding the critical threshold will cause permanent loss of magnetism.

*Technical advisory: Temperature resistance depends not only on the material grade, as well as the dimension ratios. Low-profile magnets (low Pc) risk losing magnetic properties sooner compared to rod magnets. Red status in the table indicates permanent field degradation for this specific geometry.

Two magnetic products attract each other from a wider radius than a magnet and steel setup. The setup of magnet-to-magnet produces a massive flux and a further horizon of action. Designing a strong closure? Apply two magnets instead of one magnet and a striker plate. Exercise caution that when attracting two neodymiums, the collision energy is huge. The levitation is marginally weaker than the attraction, but still impressive.
*The magnetic induction in repulsion mode reaches ~0 Gs at the geometric center of the gap (due to field cancellation).
Important: Figures show friction force of a pair of matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

Table 7: Safety (HSE) (electronics) - precautionary measures
MP 62x42x25 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	32.5 cm

A strong magnetic field is a serious hazard to electronic devices and pacemakers. These neodymiums produce a field that disrupts operation of digital equipment. Remember: the invisible magnetic field passes through tissues and glass. Exceptional care must be exercised by people with hearing aids and insulin pumps. The risk also applies to: automatic timepieces, car keys, speakers, and screens. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

MP 62x42x25 / N38

Start from (mm)	Speed (km/h)	Energy (J)

50 mm	31.49 km/h (8.75 m/s)	11.72 J
100 mm	44.16 km/h (12.27 m/s)	23.04 J

NdFeB products are very brittle – a violent impact against metal can result in shattering. Watch the impact speed – a neodymium left loose becomes dangerous. Impact energy can cause material chips or dangerous crushing to skin. Be sure to control the product during mounting so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h means shattering of the neodymium. Wear eye protection when handling with large magnets.

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

The magnetic field penetrates through water without any losses. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Shear force

*Caution: On a vertical wall, the magnet holds merely approx. 20-30% of its perpendicular strength.

2. Plate thickness effect

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

3. Thermal stability

*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) = 0.64

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-shaped magnet MP 62x42x25 / 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 58.67 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. One turn too many can destroy the magnet, so do it slowly. The flat screw head should evenly press the magnet. 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.

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.

This model is characterized by dimensions Ø62x25 mm and a weight of 306.31 g. The key parameter here is the lifting capacity amounting to approximately 58.67 kg (force ~575.60 N). The mounting hole diameter is precisely 42 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 neodymium magnets.

Benefits

In addition to their pulling strength, neodymium magnets provide the following advantages:

Their magnetic field is durable, and after around ten years it drops only by ~1% (according to research),
They maintain their magnetic properties even under external field action,
In other words, due to the smooth layer of nickel, the element becomes visually attractive,
They show high magnetic induction at the operating surface, which affects their effectiveness,
Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling operation at temperatures approaching 230°C and above...
Possibility of individual machining as well as adapting to atypical conditions,
Fundamental importance in future technologies – they find application in computer drives, electric motors, medical equipment, as well as other advanced devices.
Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which allows their use in small systems

Weaknesses

Disadvantages of neodymium magnets:

To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
NdFeB magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
Magnets exposed to a humid environment can rust. Therefore while using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
Limited ability of producing threads in the magnet and complex shapes - recommended is a housing - magnet mounting.
Possible danger resulting from small fragments of magnets can be dangerous, in case of ingestion, which becomes key in the context of child health protection. Additionally, small components of these products can be problematic in diagnostics medical after entering the body.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities

Holding force characteristics

Maximum magnetic pulling force – what it depends on?

The lifting capacity listed is a result of laboratory testing executed under specific, ideal conditions:

on a base made of mild steel, optimally conducting the magnetic field
whose transverse dimension reaches at least 10 mm
characterized by even structure
without any clearance between the magnet and steel
for force applied at a right angle (pull-off, not shear)
at temperature approx. 20 degrees Celsius

Lifting capacity in practice – influencing factors

Bear in mind that the magnet holding may be lower depending on elements below, starting with the most relevant:

Clearance – existence of foreign body (paint, dirt, gap) acts as an insulator, which reduces capacity rapidly (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 several 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).
Plate material – mild steel attracts best. Higher carbon content lower magnetic properties and lifting capacity.
Base smoothness – the smoother and more polished the surface, the better the adhesion and stronger the hold. Roughness acts like micro-gaps.
Temperature influence – high temperature reduces pulling force. Too high temperature can permanently damage the magnet.

Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under shearing force the load capacity is reduced by as much as 5 times. Moreover, even a minimal clearance between the magnet and the plate reduces the load capacity.

H&S for magnets

This is not a toy

Adult use only. Small elements can be swallowed, leading to intestinal necrosis. Keep out of reach of children and animals.

Impact on smartphones

A powerful magnetic field disrupts the operation of magnetometers in smartphones and navigation systems. Keep magnets near a device to avoid breaking the sensors.

Keep away from computers

Device Safety: Strong magnets can ruin data carriers and delicate electronics (heart implants, hearing aids, mechanical watches).

Magnets are brittle

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

Thermal limits

Avoid heat. Neodymium magnets are sensitive to temperature. If you require operation above 80°C, look for special high-temperature series (H, SH, UH).

Health Danger

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

Fire risk

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

Bone fractures

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

Safe operation

Before use, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.

Allergy Warning

It is widely known that the nickel plating (standard magnet coating) is a strong allergen. If your skin reacts to metals, refrain from touching magnets with bare hands and opt for encased magnets.

Attention! Learn more about risks in the article: Safety of working with magnets.
