Magnetic force weakens significantly per each millimeter of spacing. Keep in mind that even the smallest gap (e.g., dirt, paint, veneer) noticeably diminishes the holding power. Neodymiums work optimally at the point of direct contact; distance weakens the force. Observe how rapidly the parameters drop, when the magnet does not touch flatly to the metal substrate. When planning the arrangement, eliminate additional spacers.

The following data defines the theoretical shear load necessary to cause the slippage of the magnet downwards on a upright steel wall (assuming standard friction). The holding force depends on the air gap between the magnet and the metal.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces
MW 8x8 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.61 kg / 1.34 pounds 609.0 g / 6.0 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.41 kg / 0.90 pounds 406.0 g / 4.0 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.20 kg / 0.45 pounds 203.0 g / 2.0 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.02 kg / 2.24 pounds 1015.0 g / 10.0 N

When placing a holder on a vertical wall (e.g., a board), it you can count on only approx. 20%-30% of nominal attraction strength. Gravitational force as well as a low friction coefficient cause that magnets move down faster than they pull off. Designing a wall mount? Consider that the sliding force is much weaker than the perpendicular breakaway force. On a smooth steel, the magnet will slide down under a significantly smaller load. Using a rubber layer can effectively raise the stability.

2 mm	50%	1.02 kg / 2.24 pounds 1015.0 g / 10.0 N

12 mm	100%	2.03 kg / 4.48 pounds 2030.0 g / 19.9 N

A thin metal plate is not enough to focus the entire magnetic field, which squanders power of the holder. If you attach a powerful product to a too thin substrate, the field will penetrate right through and the holding will be smaller. To squeeze 100% of this neodymium's potential, you need a suitably thick backing of metal. The saturation effect causes that on delicate walls (e.g., appliance housings), the holder holds weaker. We advise picking the steel dimension according to the table below.

Table 5: Thermal resistance (stability) - resistance threshold

Ordinary NdFeB products lose power after exceeding the maximum temperature. Avoid high temperatures – high temperature can irreversibly destroy this magnet. As the temperature rises, the magnet's power briefly lowers. Refrain from using this magnet close to ovens higher than its safe range. Too high temperature will cause destruction of magnetic properties.

*Engineering note: Heat tolerance depends not only on the material grade, and the Permeance Coefficient Pc. Low-profile magnets (low Pc) risk losing magnetic properties under lower heat stress than long magnets. The danger warning in the table signals a risk of irreversible loss for this particular item.

Two magnets interact from a wider radius than a magnet and sheet combination. The setup of two magnets creates a more powerful interaction and a further horizon of action. Want to build a powerful holder? Utilize two neodymiums instead of a neodymium and a striker plate. Be careful that when bringing together two magnets, the pinch force is massive. The levitation is slightly lower than the connection force, but still large.
*The magnetic induction between like poles drops to ~0 Gs at the geometric center of the gap (resulting from vector opposition).
* Results refer to shear force of two matching magnets (friction coefficient ~0.15 for Ni-Ni plating).

Table 7: Safety (HSE) (electronics) - warnings
MW 8x8 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	5.5 cm
Hearing aid	10 Gs (1.0 mT)	4.0 cm
Timepiece	20 Gs (2.0 mT)	3.5 cm

Car key	50 Gs (5.0 mT)	2.5 cm
Payment card	400 Gs (40.0 mT)	1.0 cm
HDD hard drive	600 Gs (60.0 mT)	1.0 cm

A strong magnetic field is a serious hazard to electronic devices and pacemakers. These magnets generate a flux that prevents correct functioning of sensitive medical devices. Be aware: the invisible magnetic field passes through tissues and plastic. Special caution must be exercised by people with hearing aids and drug dispensers. The risk also applies to: mechanical watches, remotes, speakers, and displays. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Table 8: Impact energy (kinetic energy) - warning
MW 8x8 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	26.19 km/h (7.28 m/s)	0.08 J
30 mm	45.29 km/h (12.58 m/s)	0.24 J
50 mm	58.47 km/h (16.24 m/s)	0.40 J
100 mm	82.68 km/h (22.97 m/s)	0.80 J

Magnetic elements are very brittle – a strong collision with metal causes immediate chipping. Watch the impact speed – a magnet released freely turns into a projectile. Kinetic force can cause material chips or painful pinches to skin. Be sure to control the product during installation so it doesn't hit violently against the metal. A contact at a velocity of dozens of km/h ends with a crack of the neodymium. Wear eye protection when handling with large magnets.

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

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. Sliding resistance

*Warning: On a vertical wall, the magnet retains merely a fraction of its perpendicular strength.

2. Steel thickness impact

*Thin steel (e.g. 0.5mm PC case) severely limits 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) = 0.89

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 presented product is an exceptionally strong cylindrical magnet, composed of durable NdFeB material, which, at dimensions of Ø8x8 mm, guarantees optimal power. This specific item is characterized by a tolerance of ±0.1mm and professional build quality, making it an ideal solution for professional engineers and designers. As a magnetic rod with significant force (approx. 2.03 kg), this product is available off-the-shelf from our European logistics center, ensuring rapid order fulfillment. Moreover, its Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, ensuring 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 19.92 N with a weight of only 3.02 g, this rod is indispensable in electronics and wherever low weight is crucial.

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

Magnets NdFeB grade N38 are strong enough for the majority of applications in automation and machine building, where extreme miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø8x8), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.

The presented product is a neodymium magnet with precisely defined parameters: diameter 8 mm and height 8 mm. The value of 19.92 N means that the magnet is capable of holding a weight many times exceeding its own mass of 3.02 g. The product has a [NiCuNi] coating, which protects the surface against oxidation, giving it an aesthetic, silvery shine.

This rod magnet is magnetized axially (along the height of 8 mm), which means that the N and S poles are located on the flat, circular surfaces. Such an arrangement is standard 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 diametrically if your project requires it.

Pros and cons of Nd₂Fe₁₄B magnets.

Advantages

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

They virtually do not lose power, because even after ten years the performance loss is only ~1% (according to literature),
They show high resistance to demagnetization induced by external disturbances,
A magnet with a shiny gold surface looks better,
Magnets are distinguished by impressive magnetic induction on the surface,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
Thanks to flexibility in shaping and the capacity to adapt to specific needs,
Universal use in high-tech industry – they serve a role in computer drives, electric motors, medical equipment, as well as modern systems.
Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which allows their use in miniature devices

Limitations

What to avoid - cons of neodymium magnets and proposals for their use:

At strong impacts they can break, therefore we recommend placing them in special holders. 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 strength. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as 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 as well as corrosion.
We recommend cover - magnetic holder, due to difficulties in producing nuts inside the magnet and complicated forms.
Possible danger related to microscopic parts of magnets can be dangerous, if swallowed, which gains importance in the context of child health protection. Additionally, small elements of these devices are able to be problematic in diagnostics medical when they are in the body.
With large orders the cost of neodymium magnets is economically unviable,

Holding force characteristics

Highest magnetic holding force – what affects it?

Information about lifting capacity was determined for the most favorable conditions, taking into account:

on a base made of structural steel, optimally conducting the magnetic flux
possessing a thickness of at least 10 mm to avoid saturation
characterized by lack of roughness
with zero gap (without paint)
during detachment in a direction vertical to the mounting surface
at temperature approx. 20 degrees Celsius

Impact of factors on magnetic holding capacity in practice

Effective lifting capacity is influenced by working environment parameters, including (from most important):

Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
Force direction – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
Plate material – mild steel gives the best results. Higher carbon content decrease magnetic permeability and lifting capacity.
Plate texture – ground elements ensure maximum contact, which increases force. Uneven metal reduce efficiency.
Thermal conditions – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).

Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Moreover, even a small distance between the magnet and the plate reduces the holding force.

Warnings

Operating temperature

Regular neodymium magnets (grade N) lose power when the temperature surpasses 80°C. Damage is permanent.

Metal Allergy

Nickel alert: The nickel-copper-nickel coating consists of nickel. If an allergic reaction occurs, cease working with magnets and use protective gear.

Risk of cracking

NdFeB magnets are ceramic materials, which means they are very brittle. Clashing of two magnets leads to them shattering into shards.

Choking Hazard

Absolutely keep magnets away from children. Risk of swallowing is high, and the effects of magnets clamping inside the body are very dangerous.

Cards and drives

Data protection: Neodymium magnets can ruin payment cards and sensitive devices (pacemakers, hearing aids, timepieces).

Magnetic interference

An intense magnetic field interferes with the operation of magnetometers in smartphones and navigation systems. Maintain magnets near a smartphone to prevent breaking the sensors.

Conscious usage

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

Danger to pacemakers

Individuals with a ICD have to maintain an absolute distance from magnets. The magnetic field can stop the functioning of the life-saving device.

Bodily injuries

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

Dust explosion hazard

Fire hazard: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this risks ignition.

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