Magnetic force drops drastically with every subsequent millimeter of gap. Note that even the smallest gap (e.g., contamination, paint, dust) strongly diminishes the holding power. Magnets operate most effectively in perfect adhesion; distance kills the force. Notice how quickly the parameters drop, when the product does not touch directly to the steel surface. When calculating the assembly, avoid unnecessary gaps.

Table 2: Shear load (vertical surface)
MW 8x20 / N38

This section shows the estimated shear load necessary to start the downward movement of the magnet down against a vertical metal surface (considering typical friction coefficient). The holding force varies with the air gap between the magnet and the metal.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MW 8x20 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
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
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.13 kg / 0.29 lbs 130.0 g / 1.3 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 hanging a element on a upright wall (e.g., a board), it will only hold barely about 1/5 of its nominal power. Gravitational force as well as a low friction coefficient cause that products slide down easier than they detach. Want to create a vertical fastening? Note that the shear force is noticeably lower than the maximum static pull force. On a painted metal, the holder will slip down under a much lighter load. Utilizing a rubberized pad can significantly increase the grip.

2 mm	50%	0.65 kg / 1.43 lbs 650.0 g / 6.4 N
3 mm	75%	0.98 kg / 2.15 lbs 975.0 g / 9.6 N

11 mm	100%	1.30 kg / 2.87 lbs 1300.0 g / 12.8 N
12 mm	100%	1.30 kg / 2.87 lbs 1300.0 g / 12.8 N

A too thin steel is incapable of conduct the full magnetic flux, which wastes potential of the holder. If you mount a strong magnet to a thin surface, the magnetism will penetrate right through and the holding will be smaller. To achieve full efficiency of this neodymium's potential, you need a suitably thick element of steel. The saturation phenomenon causes that on thin elements (e.g., car bodies), the magnet works worse. We suggest choosing the steel dimension according to the table below.

Table 5: Working in heat (stability) - resistance threshold
MW 8x20 / N38

Ambient temp. (°C)	Power loss	Remaining pull (kg/lbs/g/N)	Status

Ordinary NdFeB products lose power above the temperature limit. Avoid high temperatures – high temperature can permanently damage this product. With increasing heat, the magnet's power temporarily decreases. Avoid using this magnet near heat sources exceeding its safe range. Ignoring the limit will lead to permanent loss of magnetic properties.

*Engineering note: Thermal stability depends not only on the material grade, but also on the magnet's shape. Thin magnets (low Pc) are more susceptible to demagnetization under lower heat stress than taller cylinders. 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 neodymium and metal combination. Such a system of two magnets creates a more powerful interaction and a larger range of performance. Designing a powerful holder? Apply two magnets instead of one magnet and a striker plate. Be careful that when bringing together two magnets, the collision energy is massive. The repulsion force is slightly lower than the connection force, but still impressive.
*Flux density in repulsion mode drops to ~0 Gs at the midpoint of the gap (resulting from vector opposition).
* Estimates show shear force of a pair of matching magnets (friction coefficient ~0.15 for Ni-Ni plating).

Extremely neodym field poses a real danger to electronics as well as medical implants. These neodymiums generate a flux that prevents correct functioning of digital equipment. Be aware: the invisible magnetic field acts through matter and housings. Exceptional care must be taken by people with hearing aids and insulin pumps. The risk also applies to: mechanical watches, car keys, speakers, and screens. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

Table 8: Impact energy (cracking risk) - 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

Neodymium magnets are very brittle – a collision with steel can result in shattering. Watch the impact speed – a magnet released freely becomes dangerous. Striking energy can trigger coating fragments or painful pinches to skin. Hold the magnet firmly during mounting 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 working with large magnets.

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

In water, the magnet feels stronger thanks to Archimedes' principle. Buoyancy helps in lifting finds.

1. Vertical hold

*Note: On a vertical surface, the magnet retains only ~20% of its nominal pull.

2. Plate thickness effect

*Thin metal sheet (e.g. computer case) severely limits the holding force.

3. Power loss vs temp

*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

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 extremely powerful cylinder magnet, made from modern NdFeB material, which, at dimensions of Ø8x20 mm, guarantees the highest energy density. This specific item is characterized by high dimensional repeatability and industrial build quality, making it an ideal solution for the most demanding engineers and designers. As a cylindrical magnet with significant force (approx. 1.30 kg), this product is in stock from our European logistics center, ensuring rapid order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating effectively protects it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

This model is created for building electric motors, advanced Hall effect sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the high power of 12.71 N with a weight of only 7.54 g, this cylindrical magnet is indispensable in miniature devices and wherever low weight is crucial.

Due to the brittleness of the NdFeB material, we absolutely advise against force-fitting (so-called press-fit), as this risks chipping the coating of this precision component. To ensure stability in industry, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.

Grade N38 is the most popular standard for industrial neodymium magnets, offering an optimal price-to-power ratio and high resistance to demagnetization. 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 store.

The presented product is a neodymium magnet with precisely defined parameters: diameter 8 mm and height 20 mm. The value of 12.71 N means that the magnet is capable of holding a weight many times exceeding its own mass of 7.54 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 20 mm), which means that the N and S poles are located on the flat, circular surfaces. Thanks to this, the magnet can be easily glued into a hole and achieve a strong field on the front surface. On request, we can also produce versions magnetized through the diameter if your project requires it.

Advantages as well as disadvantages of rare earth magnets.

Strengths

Besides their magnetic performance, neodymium magnets are valued for these benefits:

They have constant strength, and over more than ten years their attraction force decreases symbolically – ~1% (in testing),
Neodymium magnets are distinguished by exceptionally resistant to demagnetization caused by external magnetic fields,
Thanks to the metallic finish, the surface of nickel, gold, or silver-plated gives an modern appearance,
The surface of neodymium magnets generates a concentrated magnetic field – this is a distinguishing feature,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
Possibility of precise forming and optimizing to concrete needs,
Key role in future technologies – they find application in HDD drives, electric motors, medical devices, also modern systems.
Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Weaknesses

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

They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also improves its resistance to damage
We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
Magnets exposed to a humid environment can rust. Therefore when using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
We recommend casing - magnetic mount, due to difficulties in producing threads inside the magnet and complex forms.
Possible danger related to microscopic parts of magnets pose a threat, in case of ingestion, which gains importance in the aspect of protecting the youngest. Furthermore, small components of these magnets are able to complicate diagnosis medical in case of swallowing.
Due to complex production process, their price is relatively high,

Lifting parameters

Detachment force of the magnet in optimal conditions – what contributes to it?

The lifting capacity listed is a measurement result performed under standard conditions:

using a base made of high-permeability steel, acting as a magnetic yoke
with a cross-section of at least 10 mm
with an ground touching surface
with total lack of distance (without coatings)
during pulling in a direction perpendicular to the plane
in neutral thermal conditions

What influences lifting capacity in practice

Bear in mind that the application force may be lower depending on elements below, in order of importance:

Clearance – existence of any layer (rust, dirt, air) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
Loading method – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet exhibits much less (typically approx. 20-30% of nominal force).
Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
Steel grade – the best choice is pure iron steel. Hardened steels may generate lower lifting capacity.
Surface structure – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Roughness acts like micro-gaps.
Thermal environment – temperature increase results in weakening of induction. It is worth remembering the thermal limit for a given model.

Lifting capacity testing was carried out on a smooth plate of optimal thickness, under perpendicular forces, however under attempts to slide the magnet the holding force is lower. Additionally, even a slight gap between the magnet and the plate decreases the load capacity.

Safety rules for work with neodymium magnets

Immense force

Use magnets consciously. Their huge power can shock even experienced users. Be vigilant and respect their force.

Material brittleness

Watch out for shards. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. We recommend safety glasses.

Safe distance

Avoid bringing magnets near a wallet, laptop, or screen. The magnetism can destroy these devices and wipe information from cards.

Pinching danger

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

Flammability

Machining of NdFeB material poses a fire hazard. Neodymium dust reacts violently with oxygen and is difficult to extinguish.

Swallowing risk

Strictly store magnets out of reach of children. Risk of swallowing is high, and the effects of magnets clamping inside the body are tragic.

Operating temperature

Avoid heat. NdFeB magnets are susceptible to temperature. If you need resistance above 80°C, look for HT versions (H, SH, UH).

Allergy Warning

Nickel alert: The nickel-copper-nickel coating contains nickel. If redness happens, cease handling magnets and wear gloves.

Compass and GPS

A powerful magnetic field negatively affects the functioning of compasses in smartphones and GPS navigation. Do not bring magnets near a smartphone to avoid damaging the sensors.

Health Danger

Warning for patients: Powerful magnets disrupt electronics. Keep minimum 30 cm distance or request help to handle the magnets.
