Magnetic force drops sharply with every subsequent millimeter of distance. Note that every additional insulation layer (e.g., dirt, paint, dust) noticeably reduces the pull force. Magnetic products hold most effectively in perfect adhesion; air break drastically cuts the force. Notice how quickly the pull force plummet, when the magnet does not touch flatly to the metal substrate. When designing the arrangement, avoid unnecessary gaps.

The following data presents the approximate holding capacity sufficient to start the shifting of the magnet vertically against a vertical steel wall (considering standard friction). This value is relative to the distance between the magnet and the metal.

Table 3: Wall mounting (shearing) - vertical pull
MW 33x10 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	7.10 kg / 15.66 lbs 7101.0 g / 69.7 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	4.73 kg / 10.44 lbs 4734.0 g / 46.4 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	2.37 kg / 5.22 lbs 2367.0 g / 23.2 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	11.84 kg / 26.09 lbs 11835.0 g / 116.1 N

When hanging a holder on a vertical wall (e.g., a board), it you can count on barely approx. 1/5 of its nominal power. Gravity as well as a weak degree of grip mean that holders slip easier than they pull off. Planning a wall mount? Remember that the sliding force is much weaker than the perpendicular breakaway force. On a smooth steel, the holder will give way down under a significantly smaller weight. Utilizing a rubberized layer can drastically improve the result.

A thin metal plate is not enough to focus the entire magnetic field, which weakens actual performance of the magnet. Should you install a neodymium to a thin surface, the flux will pass right through and the holding will be smaller. To utilize the maximum of this neodymium's power, you need a suitably thick backing of steel. The material oversaturation means that on thin elements (e.g., thin profiles), the magnet works worse. We suggest choosing the steel dimension based on the following data.

Ordinary NdFeB products change their properties strength past the thermal threshold. Avoid high temperatures – excessive heat can permanently destroy this magnet. With every degree above norm, the magnet's power temporarily drops. Do not use this product near heat sources higher than its operating temperature limit. Ignoring the limit will result in irreversible degradation of magnetic properties.

*Engineering note: Temperature resistance depends not only on the material grade, and the Permeance Coefficient Pc. Low-profile magnets (low permeance coefficient) risk losing magnetic properties sooner than long magnets. Warning indicator in the table points to a risk of irreversible loss for this specific geometry.

Two magnetic products interact from a wider radius than a magnet and steel setup. The connection of two magnets generates a stronger field and a further horizon of action. Planning to create a solid fastener? Utilize two neodymiums instead of a neodymium and a striker plate. Exercise caution that when attracting two neodymiums, the pinch force is massive. The repulsion force is slightly lower than the connection force, but still large.
*The magnetic induction between like poles drops to ~0 Gs in the exact middle of the gap (due to field cancellation).
* Results show shear force of dual matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

Powerful magnet radiation is a serious hazard to electronics and medical implants. These NdFeB products generate a flux that disrupts operation of digital equipment. Notice: the invisible magnetic field passes through tissues and plastic. Exceptional care must be taken by people with hearing aids and insulin pumps. Also at risk are: mechanical watches, car keys, speakers, and displays. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

Table 8: Impact energy (cracking risk) - collision effects
MW 33x10 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	22.07 km/h (6.13 m/s)	1.21 J
30 mm	33.74 km/h (9.37 m/s)	2.82 J
50 mm	43.34 km/h (12.04 m/s)	4.65 J
100 mm	61.26 km/h (17.02 m/s)	9.29 J

NdFeB products are very brittle – a collision with steel risks their cracking. Pay attention to connection velocity – a magnet released freely speeds with massive force. Impact energy can trigger coating fragments or injury to fingers. Be sure to control the product during mounting so it doesn't slam with momentum against the metal. A collision at high speed means shattering of the magnet. Use safety goggles when working with powerful specimens.

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

Water displaces steel, making heavy objects slightly lighter. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Sliding resistance

*Warning: On a vertical wall, the magnet holds just ~20% of its nominal pull.

2. Plate thickness effect

*Thin steel (e.g. computer case) drastically weakens the holding force.

3. Power loss vs temp

*For N38 grade, 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) = 0.40

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.

This product is an exceptionally strong cylindrical magnet, composed of durable NdFeB material, which, at dimensions of Ø33x10 mm, guarantees the highest energy density. This specific item is characterized by an accuracy of ±0.1mm and professional build quality, making it an ideal solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 23.67 kg), this product is in stock from our European logistics center, ensuring lightning-fast order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.

It successfully proves itself in modeling, advanced automation, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 232.15 N with a weight of only 64.15 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 immediate cracking of this professional component. To ensure stability in industry, anaerobic resins are used, which do not react with the nickel coating 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 high resistance to demagnetization. If you need the strongest magnets in the same volume (Ø33x10), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.

This model is characterized by dimensions Ø33x10 mm, which, at a weight of 64.15 g, makes it an element with high magnetic energy density. The key parameter here is the lifting capacity amounting to approximately 23.67 kg (force ~232.15 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 33 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 Nd₂Fe₁₄B magnets.

Advantages

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

They have unchanged lifting capacity, and over more than 10 years their attraction force decreases symbolically – ~1% (in testing),
They possess excellent resistance to magnetism drop due to external magnetic sources,
In other words, due to the shiny surface of gold, the element looks attractive,
They show high magnetic induction at the operating surface, making them more effective,
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 forming and the capacity to modify to complex applications,
Key role in future technologies – they are used in HDD drives, electric drive systems, medical devices, as well as other advanced devices.
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 heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
Magnets exposed to a humid environment can rust. Therefore during using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
We recommend casing - magnetic mechanism, due to difficulties in creating nuts inside the magnet and complicated forms.
Health risk related to microscopic parts of magnets are risky, if swallowed, which is particularly important 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.
Due to complex production process, their price is relatively high,

Lifting parameters

Maximum magnetic pulling force – what it depends on?

The declared magnet strength refers to the limit force, measured under optimal environment, namely:

using a plate made of high-permeability steel, serving as a ideal flux conductor
whose transverse dimension is min. 10 mm
with a surface free of scratches
without the slightest clearance between the magnet and steel
during pulling in a direction perpendicular to the plane
at temperature room level

Lifting capacity in practice – influencing factors

In real-world applications, the real power depends on a number of factors, ranked from crucial:

Clearance – the presence of foreign body (paint, tape, gap) interrupts the magnetic circuit, which lowers 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 nominal value.
Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
Material type – the best choice is pure iron steel. Cast iron may attract less.
Surface finish – full contact is possible only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
Temperature – temperature increase causes a temporary drop of induction. Check the maximum operating temperature for a given model.

Lifting capacity testing was performed on a smooth plate of suitable thickness, under perpendicular forces, in contrast under shearing force the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate decreases the holding force.

Safe handling of neodymium magnets

Health Danger

Medical warning: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.

Magnet fragility

Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. Eye protection is mandatory.

Mechanical processing

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

Immense force

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

Threat to navigation

A powerful magnetic field negatively affects the operation of compasses in smartphones and GPS navigation. Keep magnets near a smartphone to prevent damaging the sensors.

Product not for children

Only for adults. Small elements can be swallowed, causing severe trauma. Store out of reach of kids and pets.

Heat warning

Control the heat. Heating the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and pulling force.

Magnetic media

Do not bring magnets near a wallet, computer, or screen. The magnetic field can irreversibly ruin these devices and erase data from cards.

Bone fractures

Danger of trauma: The pulling power is so immense that it can result in blood blisters, pinching, and broken bones. Use thick gloves.

Metal Allergy

Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction happens, immediately stop handling magnets and use protective gear.
