Magnetic force drops sharply with every mm of gap. Remember that even a very thin break (e.g., dirt, paint, veneer) significantly reduces the pull force. Neodymiums work strongest at the point of direct contact; air break weakens the power. Notice how flashily the load capacity plummet, when the product does not adhere flatly to the metal substrate. When calculating the arrangement, discard additional spacers.

The table below indicates the theoretical holding capacity necessary to start the slippage of the magnet vertically on a upright steel wall (assuming typical friction). This parameter is relative to the separation distance between the magnet and the metal.

Table 3: Wall mounting (shearing) - behavior on slippery surfaces
MW 5x2 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.21 kg / 0.46 LBS 210.0 g / 2.1 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.14 kg / 0.31 LBS 140.0 g / 1.4 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.07 kg / 0.15 LBS 70.0 g / 0.7 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.35 kg / 0.77 LBS 350.0 g / 3.4 N

When hanging a element on a upright plane (e.g., a fridge), it will only hold barely about 20%-30% of its nominal power. Gravity as well as a low friction coefficient cause that products move down faster than they pop off the substrate. Designing a wall mount? Remember that the shear force is much weaker than the maximum static pull force. On a painted metal, the magnet will give way down under a significantly smaller load. Utilizing a rubberized pad can effectively improve the result.

12 mm	100%	0.70 kg / 1.54 LBS 700.0 g / 6.9 N

A thin metal plate is unable to absorb the entire magnetic field, which squanders power of the holder. If you attach a powerful product to a thin surface, the flux will pass right through and the pull force will drop sharply. To utilize 100% of this magnet's potential, you need a suitably thick element of steel. The saturation effect means that on thin elements (e.g., car bodies), the product holds weaker. We recommend selecting the steel cross-section according to the table below.

100 °C	-28.8%	0.50 kg / 1.10 LBS 498.4 g / 4.9 N

Classic neodymiums irreversibly lose power past the thermal threshold. Protect against heat – high temperature can irreversibly destroy this product. With increasing heat, the neodymium's capacity briefly drops. Avoid using this product close to ovens exceeding its operating temperature limit. Exceeding the critical threshold will cause permanent loss of magnetic properties.

*Technical advisory: Heat tolerance depends not only on the material grade, and the Permeance Coefficient Pc. Low-profile magnets (low Pc) risk losing magnetic properties sooner than taller cylinders. The danger warning in the table points to permanent field degradation for this specific geometry.

Two magnetic products attract each other from a significantly greater distance than a neodymium and metal setup. Such a system of two magnets creates a more powerful interaction and a wider radius of performance. Want to build a powerful holder? Utilize two neodymiums instead of one magnet and a striker plate. Remember that when attracting two neodymiums, the pinch force is massive. The repulsion force is a bit weaker than the connection force, but still significant.
*Flux density for N-N configuration drops to ~0 Gs in the exact middle between the magnets (caused by magnetic field nullification).
Note: Figures show friction force of two identical magnets (friction coefficient ~0.15 for Ni-Ni layer).

Extremely neodym field poses a serious hazard to IT equipment and medical implants. These neodymiums generate a flux that prevents correct functioning of sensitive medical devices. Notice: the invisible magnetic field acts through matter and plastic. Special caution must be exercised by people with hearing aids and drug dispensers. Also at risk are: automatic timepieces, car keys, membranes, and displays. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Table 8: Impact energy (kinetic energy) - collision effects
MW 5x2 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	49.55 km/h (13.77 m/s)	0.03 J

100 mm	156.69 km/h (43.52 m/s)	0.27 J

Magnetic elements are very brittle – a violent impact against metal risks their cracking. Watch the impact speed – a neodymium left loose becomes dangerous. Kinetic force can cause material chips or dangerous crushing to fingers. Hold the magnet firmly during mounting 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.

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

The magnetic field penetrates through water without any losses. Buoyancy helps in lifting finds.

1. Wall mount (shear)

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

2. Plate thickness effect

*Thin steel (e.g. 0.5mm PC case) severely reduces the holding force.

3. Heat tolerance

*For N38 material, the max working temp is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.50

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 offered product is an exceptionally strong rod magnet, composed of advanced NdFeB material, which, at dimensions of Ø5x2 mm, guarantees the highest energy density. The MW 5x2 / N38 component boasts high dimensional repeatability and professional build quality, making it a perfect solution for professional engineers and designers. As a cylindrical magnet with significant force (approx. 0.70 kg), this product is available off-the-shelf from our European logistics center, ensuring rapid order fulfillment. Moreover, its Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is ideal for building generators, advanced Hall effect sensors, and efficient magnetic separators, where maximum induction on a small surface counts. Thanks to the pull force of 6.83 N with a weight of only 0.29 g, this rod is indispensable in miniature devices and wherever every gram matters.

Since our magnets have a tolerance of ±0.1mm, the best method is to glue them into holes with a slightly larger diameter (e.g., 5.1 mm) using two-component epoxy glues. 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 professional neodymium magnets, offering an optimal price-to-power ratio and high resistance to demagnetization. If you need even stronger magnets in the same volume (Ø5x2), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.

The presented product is a neodymium magnet with precisely defined parameters: diameter 5 mm and height 2 mm. The key parameter here is the lifting capacity amounting to approximately 0.70 kg (force ~6.83 N), which, with such compact dimensions, proves the high grade of the NdFeB material. The product has a [NiCuNi] coating, which protects the surface against oxidation, 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 5 mm. 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 through the diameter if your project requires it.

Pros as well as cons of Nd₂Fe₁₄B magnets.

Advantages

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

Their magnetic field is maintained, and after around ten years it drops only by ~1% (according to research),
They feature excellent resistance to magnetic field loss due to external magnetic sources,
In other words, due to the aesthetic layer of nickel, the element is aesthetically pleasing,
Magnets are distinguished by extremely high magnetic induction on the outer layer,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
Thanks to flexibility in forming and the capacity to customize to complex applications,
Huge importance in modern industrial fields – they are commonly used in computer drives, electromotive mechanisms, diagnostic systems, also other advanced devices.
Thanks to concentrated force, small magnets offer high operating force, in miniature format,

Weaknesses

Disadvantages of neodymium magnets:

To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
Due to limitations in realizing nuts and complicated shapes in magnets, we recommend using a housing - magnetic mechanism.
Health risk related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child health protection. It is also worth noting that small components of these devices can be problematic in diagnostics medical when they are in the body.
Due to neodymium price, their price exceeds standard values,

Pull force analysis

Maximum magnetic pulling force – what it depends on?

The force parameter is a measurement result conducted under standard conditions:

with the contact of a yoke made of low-carbon steel, ensuring maximum field concentration
with a thickness of at least 10 mm
with an polished touching surface
without the slightest insulating layer between the magnet and steel
under vertical force direction (90-degree angle)
at ambient temperature approx. 20 degrees Celsius

Determinants of practical lifting force of a magnet

Holding efficiency is influenced by specific conditions, such as (from priority):

Clearance – existence of foreign body (rust, dirt, gap) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
Base massiveness – too thin plate causes magnetic saturation, causing part of the power to be escaped to the other side.
Chemical composition of the base – mild steel gives the best results. Alloy steels lower magnetic permeability and holding force.
Surface finish – full contact is possible only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
Thermal environment – temperature increase results in weakening of induction. Check the thermal limit for a given model.

Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under shearing force the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate lowers the lifting capacity.

Safety rules for work with NdFeB magnets

Impact on smartphones

An intense magnetic field interferes with the functioning of magnetometers in smartphones and navigation systems. Keep magnets near a smartphone to prevent damaging the sensors.

Metal Allergy

Some people suffer from a contact allergy to nickel, which is the standard coating for NdFeB magnets. Prolonged contact might lead to dermatitis. It is best to use protective gloves.

Cards and drives

Do not bring magnets close to a wallet, computer, or screen. The magnetism can irreversibly ruin these devices and erase data from cards.

Dust is flammable

Fire hazard: Rare earth powder is explosive. Avoid machining magnets in home conditions as this risks ignition.

Choking Hazard

These products are not toys. Swallowing multiple magnets can lead to them connecting inside the digestive tract, which poses a critical condition and requires immediate surgery.

Serious injuries

Protect your hands. Two powerful magnets will join instantly with a force of massive weight, destroying everything in their path. Be careful!

Magnet fragility

Beware of splinters. Magnets can fracture upon violent connection, launching sharp fragments into the air. We recommend safety glasses.

Health Danger

Patients with a pacemaker should maintain an absolute distance from magnets. The magnetism can interfere with the operation of the implant.

Heat warning

Standard neodymium magnets (grade N) lose magnetization when the temperature goes above 80°C. Damage is permanent.

Powerful field

Be careful. Neodymium magnets act from a distance and connect with huge force, often faster than you can react.
