Pulling power weakens drastically with every mm of gap. Note that even a very thin break (e.g., contamination, varnish, rust) noticeably diminishes the holding power. Magnets hold most effectively in perfect adhesion; distance weakens the force. Analyze how flashily the load capacity plummet, when the magnet does not adhere flatly to the steel surface. When designing the assembly, eliminate redundant distances.

The table below indicates the approximate shear load required to initiate the slippage of the magnet vertically against a vertical steel plate (assuming standard friction coefficient). This parameter is relative to the gap size between the magnet and the metal.

Table 3: Vertical assembly (shearing) - vertical pull
MW 8x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.65 kg / 1.44 pounds 651.0 g / 6.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.43 kg / 0.96 pounds 434.0 g / 4.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.22 kg / 0.48 pounds 217.0 g / 2.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.09 kg / 2.39 pounds 1085.0 g / 10.6 N

When hanging a magnet on a vertical surface (e.g., a fridge), it will only hold just about 20%-30% of its maximum pull force. Gravity as well as a low friction coefficient mean that magnets move down faster than they pop off the substrate. Designing a wall mount? Note that the shear force is significantly lower than the maximum static pull force. On a slippery surface, the holder will slip down under a noticeably lighter weight. Utilizing a rubberized layer can drastically improve the result.

12 mm	100%	2.17 kg / 4.78 pounds 2170.0 g / 21.3 N

A too thin steel is unable to absorb the full magnetic flux, which weakens actual performance of the holder. Should you mount a strong magnet to a too thin substrate, the magnetism will pass right through and the attraction force will be weaker. To utilize 100% of this neodymium's potential, you require a sufficiently solid backing of steel. The saturation effect causes that on delicate walls (e.g., thin profiles), the product works worse. We suggest choosing the steel thickness based on the following data.

Ordinary NdFeB products irreversibly lose power after exceeding the maximum temperature. Protect against heat – high temperature can irreversibly damage this magnet. As the temperature rises, the neodymium's power briefly drops. Refrain from using this product near heat sources exceeding its operating temperature limit. Exceeding the critical threshold will lead to destruction of magnetism.

*Important note: Thermal stability depends not only on the material grade, as well as the dimension ratios. Flat magnets (low permeance coefficient) risk losing magnetic properties sooner than taller cylinders. The danger warning in the table points to a risk of irreversible loss for this particular item.

Two magnets attract each other from a much further distance than a magnet and steel combination. The setup of two magnets generates a stronger field and a wider radius of performance. Want to build a powerful holder? Apply two magnets instead of one magnet and a steel. Be careful that when attracting two neodymiums, the impact force is extreme. The repulsion force is marginally weaker than the connection force, but still large.
*Flux density between like poles reaches ~0 Gs at the midpoint of the gap (due to field cancellation).
* Figures show sliding force of two identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

Table 7: Hazards (electronics) - precautionary measures

A strong magnetic field poses a serious hazard to IT equipment and pacemakers. These neodymiums generate a flux that prevents correct functioning of sensitive medical devices. Notice: the invisible magnetic field passes through tissues and housings. Exceptional care must be exercised by people with cochlear implants and drug dispensers. Also at risk are: mechanical watches, remotes, speakers, and displays. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Table 8: Collisions (cracking risk) - warning
MW 8x5 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	34.31 km/h (9.53 m/s)	0.09 J
30 mm	59.35 km/h (16.49 m/s)	0.26 J
50 mm	76.62 km/h (21.28 m/s)	0.43 J
100 mm	108.35 km/h (30.10 m/s)	0.85 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. Impact energy can trigger coating fragments or injury to fingers. Always hold the magnet during bringing near metal so it doesn't hit violently against the steel surface. A collision at high speed almost guarantees destruction of the magnet. Use safety goggles when playing with large magnets.

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

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

1. Shear force

*Warning: On a vertical wall, the magnet retains just approx. 20-30% of its nominal pull.

2. Efficiency vs thickness

*Thin steel (e.g. computer case) drastically weakens 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) = 0.68

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 presented product is an extremely powerful cylinder magnet, composed of durable NdFeB material, which, at dimensions of Ø8x5 mm, guarantees the highest energy density. The MW 8x5 / N38 model features high dimensional repeatability and industrial build quality, making it a perfect solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 2.17 kg), this product is in stock from our European logistics center, ensuring lightning-fast order fulfillment. Furthermore, its Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

It finds application in modeling, advanced automation, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 21.31 N with a weight of only 1.88 g, this cylindrical magnet is indispensable in electronics and wherever every gram matters.

Due to the delicate structure of the ceramic sinter, you must not use 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 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 an optimal price-to-power ratio and operational stability. If you need even stronger magnets in the same volume (Ø8x5), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

This model is characterized by dimensions Ø8x5 mm, which, at a weight of 1.88 g, makes it an element with high magnetic energy density. The key parameter here is the lifting capacity amounting to approximately 2.17 kg (force ~21.31 N), which, with such compact dimensions, proves the high power of the NdFeB material. The product has a [NiCuNi] coating, which protects the surface against external factors, giving it an aesthetic, silvery shine.

Standardly, the magnetic axis runs through the center of the cylinder, causing the greatest attraction force to occur on the bases with a diameter of 8 mm. 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.

Pros

Besides their immense field intensity, neodymium magnets offer the following advantages:

They have unchanged lifting capacity, and over nearly 10 years their attraction force decreases symbolically – ~1% (in testing),
Neodymium magnets prove to be exceptionally resistant to loss of magnetic properties caused by external field sources,
Thanks to the smooth finish, the coating of nickel, gold, or silver gives an professional appearance,
Magnets possess impressive magnetic induction on the active area,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
Thanks to flexibility in constructing and the ability to customize to unusual requirements,
Key role in high-tech industry – they find application in HDD drives, motor assemblies, diagnostic systems, and complex engineering applications.
Thanks to their power density, small magnets offer high operating force, with minimal size,

Disadvantages

Drawbacks and weaknesses of neodymium magnets: tips and applications.

They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
Neodymium magnets lose their strength 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 stability even at temperatures up to 230°C
Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
We recommend casing - magnetic mechanism, due to difficulties in producing nuts inside the magnet and complicated shapes.
Possible danger resulting from small fragments of magnets are risky, if swallowed, which is particularly important in the context of child health protection. Furthermore, small elements of these magnets are able to disrupt the diagnostic process medical in case of swallowing.
Due to neodymium price, their price exceeds standard values,

Holding force characteristics

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

The declared magnet strength represents the maximum value, recorded under laboratory conditions, namely:

using a plate made of low-carbon steel, serving as a magnetic yoke
whose transverse dimension reaches at least 10 mm
characterized by smoothness
with total lack of distance (without impurities)
during pulling in a direction perpendicular to the mounting surface
at standard ambient temperature

Determinants of practical lifting force of a magnet

Real force impacted by working environment parameters, including (from most important):

Distance (betwixt the magnet and the plate), as even a tiny clearance (e.g. 0.5 mm) can cause a reduction in force by up to 50% (this also applies to paint, rust or debris).
Pull-off angle – 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.
Steel thickness – insufficiently thick plate does not close the flux, causing part of the power to be wasted into the air.
Material composition – different alloys attracts identically. Alloy additives worsen the interaction with the magnet.
Surface condition – ground elements guarantee perfect abutment, which increases force. Rough surfaces reduce efficiency.
Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under perpendicular forces, in contrast under parallel forces the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet and the plate decreases the holding force.

Safe handling of neodymium magnets

Health Danger

Health Alert: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.

Beware of splinters

Neodymium magnets are ceramic materials, which means they are very brittle. Impact of two magnets will cause them cracking into small pieces.

Data carriers

Very strong magnetic fields can corrupt files on payment cards, HDDs, and storage devices. Keep a distance of min. 10 cm.

Permanent damage

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

Fire warning

Powder produced during grinding of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.

Adults only

Absolutely keep magnets out of reach of children. Risk of swallowing is significant, and the consequences of magnets connecting inside the body are very dangerous.

Physical harm

Big blocks can break fingers instantly. Under no circumstances put your hand between two strong magnets.

Powerful field

Handle with care. Rare earth magnets attract from a distance and connect with huge force, often faster than you can react.

Skin irritation risks

Nickel alert: The Ni-Cu-Ni coating contains nickel. If redness occurs, cease working with magnets and use protective gear.

Keep away from electronics

Note: rare earth magnets produce a field that disrupts sensitive sensors. Maintain a separation from your phone, tablet, and GPS.
