Magnetic force drops drastically with every subsequent millimeter of gap. Remember that even the smallest gap (e.g., contamination, paint, veneer) strongly reduces the pull force. Magnetic products operate strongest in perfect adhesion; gap nullifies the power. See how rapidly the pull force drop, when the magnet does not touch tightly to the steel surface. When planning the arrangement, discard additional spacers.

The following data indicates the approximate weight limit required to initiate the downward movement of the magnet vertically on a upright metal surface (assuming standard friction). The holding force varies with the gap size between the magnet and the surface.

Raw steel	µ = 0.3 30% Nominalnej Siły	0.39 kg / 0.86 LBS 390.0 g / 3.8 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.26 kg / 0.57 LBS 260.0 g / 2.6 N

Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.65 kg / 1.43 LBS 650.0 g / 6.4 N

When mounting a element on a vertical surface (e.g., a board), it will maintain just approx. 20%-30% of its nominal power. Gravity and a weak degree of grip cause that products slide down easier than they pop off the substrate. Want to create a hanger? Note that the sliding force is noticeably lower than the maximum static pull force. On a slippery surface, the element will give way down under a noticeably lighter weight. Using a rubber layer can drastically increase the grip.

A thin metal plate is unable to focus the full magnetic flux, which wastes potential of the magnet. Should you attach a powerful product to a weak sheet, the field will penetrate right through and the attraction force will be weaker. To utilize the maximum of this neodymium's potential, you require a sufficiently solid backing of steel. The material oversaturation causes that on sheet metal structures (e.g., thin profiles), the holder works worse. We suggest choosing the steel thickness according to the table below.

Standard neodymium magnets lose power past the thermal threshold. Avoid high temperatures – excessive heat can permanently damage this product. With increasing heat, the neodymium's force briefly drops. Refrain from using this product close to heaters higher than its safe range. Too high temperature will cause permanent loss of magnetism.

*Technical advisory: Temperature resistance depends not only on the material grade, and the Permeance Coefficient Pc. Low-profile magnets (low Pc) are more susceptible to demagnetization under lower heat stress than taller cylinders. Red status in the table indicates a risk of irreversible loss for this particular item.

Two strong neodymiums interact from a much further distance than a magnet and steel combination. The setup of two magnets produces a massive flux and a further horizon of action. Planning to create a powerful holder? Use a pair of magnets instead of one magnet and a striker plate. Be careful that when bringing together two magnets, the pinch force is huge. The levitation is a bit weaker than the connection force, but still significant.
*Field value in repulsion mode drops to ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
Attention: Results apply to sliding force of a pair of identical magnets (friction coefficient ~0.15 for Ni-Ni plating).

Table 7: Safety (HSE) (implants) - precautionary measures

Extremely neodym field poses a serious hazard to electronics and pacemakers. These NdFeB products generate a field that disrupts operation of digital equipment. Be aware: the invisible magnetic field acts through matter and glass. Exceptional care must be exercised by people with cochlear implants and drug dispensers. The risk also applies to: mechanical watches, remotes, speakers, and displays. Do not place the magnet near cards, hard drives, or precise measuring instruments.

Table 8: Impact energy (kinetic energy) - collision effects
MW 8x20 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	13.28 km/h (3.69 m/s)	0.05 J
30 mm	22.94 km/h (6.37 m/s)	0.15 J
50 mm	29.61 km/h (8.23 m/s)	0.26 J
100 mm	41.88 km/h (11.63 m/s)	0.51 J

Magnetic elements are prone to chipping – a collision with steel risks their cracking. Watch the impact speed – a neodymium left loose turns into a projectile. Striking energy can cause material chips or painful pinches to skin. Be sure to control the product during bringing near metal so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h means shattering of the neodymium. Wear eye protection when handling with powerful specimens.

Corrosion warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

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)

*Warning: On a vertical surface, the magnet holds only ~20% of its max power.

2. Efficiency vs thickness

*Thin metal sheet (e.g. computer case) significantly reduces the holding force.

3. Thermal stability

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 1.31

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.

This product is an extremely powerful cylinder magnet, composed of modern NdFeB material, which, at dimensions of Ø8x20 mm, guarantees optimal power. The MW 8x20 / N38 component is characterized by a tolerance of ±0.1mm and professional build quality, making it a perfect solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 1.30 kg), this product is in stock from our European logistics center, ensuring rapid order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.

It successfully proves itself in modeling, advanced robotics, and broadly understood industry, serving as a fastening or actuating element. Thanks to the high power of 12.71 N with a weight of only 7.54 g, this rod is indispensable in miniature devices and wherever low weight is crucial.

Since our magnets have a very precise dimensions, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 8.1 mm) using epoxy glues. To ensure long-term durability in automation, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.

Grade N38 is the most popular standard for professional neodymium magnets, offering a great economic balance and operational stability. If you need even stronger magnets in the same volume (Ø8x20), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.

This model is characterized by dimensions Ø8x20 mm, which, at a weight of 7.54 g, makes it an element with high magnetic energy density. The key parameter here is the holding force amounting to approximately 1.30 kg (force ~12.71 N), which, with such defined dimensions, proves the high grade of the NdFeB material. The product has a [NiCuNi] coating, which secures it against external factors, giving it an aesthetic, silvery shine.

This rod magnet is magnetized axially (along the height of 20 mm), which means that the N and S poles are located on the flat, circular surfaces. Such an arrangement is most desirable when connecting magnets in stacks (e.g., in filters) or when mounting in sockets at the bottom of a hole. On request, we can also produce versions magnetized through the diameter if your project requires it.

Advantages and disadvantages of Nd₂Fe₁₄B magnets.

Benefits

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

They retain full power for almost 10 years – the loss is just ~1% (in theory),
They are resistant to demagnetization induced by external disturbances,
By using a decorative layer of nickel, the element has an modern look,
They are known for high magnetic induction at the operating surface, which affects their effectiveness,
Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
Thanks to versatility in shaping and the ability to customize to client solutions,
Versatile presence in modern industrial fields – they are utilized in computer drives, motor assemblies, advanced medical instruments, as well as industrial machines.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Disadvantages

Disadvantages of neodymium magnets:

To avoid cracks under impact, we suggest using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their strength 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. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
We recommend cover - magnetic mechanism, due to difficulties in creating threads inside the magnet and complicated forms.
Possible danger related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child health protection. Additionally, small elements of these devices are able to disrupt the diagnostic process 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

Lifting parameters

Breakaway strength of the magnet in ideal conditions – what contributes to it?

The lifting capacity listed is a theoretical maximum value performed under standard conditions:

on a base made of structural steel, perfectly concentrating the magnetic flux
with a thickness of at least 10 mm
with an ideally smooth contact surface
under conditions of no distance (surface-to-surface)
under perpendicular application of breakaway force (90-degree angle)
at standard ambient temperature

What influences lifting capacity in practice

In practice, the actual lifting capacity depends on several key aspects, listed from crucial:

Gap between surfaces – even a fraction of a millimeter of distance (caused e.g. by varnish or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
Steel grade – ideal substrate is high-permeability steel. Cast iron may attract less.
Smoothness – full contact is obtained only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
Operating temperature – NdFeB sinters have a negative temperature coefficient. When it is hot they lose power, and in frost gain strength (up to a certain limit).

Lifting capacity was determined with the use of a polished steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under parallel forces the load capacity is reduced by as much as fivefold. Moreover, even a small distance between the magnet’s surface and the plate decreases the load capacity.

Warnings

Sensitization to coating

Studies show that nickel (the usual finish) is a strong allergen. For allergy sufferers, refrain from touching magnets with bare hands or opt for versions in plastic housing.

Safe operation

Before use, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.

Finger safety

Danger of trauma: The pulling power is so immense that it can result in hematomas, crushing, and even bone fractures. Protective gloves are recommended.

Precision electronics

GPS units and smartphones are extremely susceptible to magnetism. Direct contact with a strong magnet can permanently damage the internal compass in your phone.

Heat sensitivity

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

Material brittleness

NdFeB magnets are sintered ceramics, which means they are very brittle. Collision of two magnets leads to them cracking into small pieces.

Mechanical processing

Dust produced during grinding of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.

Implant safety

Warning for patients: Strong magnetic fields affect electronics. Maintain at least 30 cm distance or ask another person to work with the magnets.

Cards and drives

Data protection: Neodymium magnets can ruin data carriers and sensitive devices (heart implants, medical aids, timepieces).

Do not give to children

Product intended for adults. Tiny parts pose a choking risk, leading to intestinal necrosis. Store away from children and animals.
