Magnetic force weakens drastically with every subsequent millimeter of spacing. Remember that even a very thin break (e.g., dirt, varnish, veneer) significantly diminishes the holding power. Neodymiums operate optimally in perfect adhesion; gap weakens the force. Notice how flashily the parameters drop, when the product does not touch flatly to the steel surface. When planning the mounting, discard additional spacers.

The table below presents the theoretical shear load needed to initiate the sliding of the magnet vertically against a upright steel wall (considering standard friction). This parameter is relative to the distance between the magnet and the metal.

Table 3: Wall mounting (shearing) - behavior on slippery surfaces
MW 10x20 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.67 kg / 1.47 lbs 669.0 g / 6.6 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.45 kg / 0.98 lbs 446.0 g / 4.4 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.22 kg / 0.49 lbs 223.0 g / 2.2 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.12 kg / 2.46 lbs 1115.0 g / 10.9 N

When hanging a element on a vertical surface (e.g., a fridge), it will maintain just approx. 20%-30% of its nominal power. Gravitational force and a low friction coefficient influence the fact that products move down faster than they detach. Designing a hanger? Consider that the sliding force is much weaker than the maximum static pull force. On a painted metal, the magnet will slip down under a noticeably lighter load. Utilizing a rubberized coating can significantly improve the result.

12 mm	100%	2.23 kg / 4.92 lbs 2230.0 g / 21.9 N

A thin metal plate is not enough to absorb the full magnetic flux, which squanders power of the holder. If you install a neodymium to a too thin substrate, the magnetism will pass right through and the attraction force will be weaker. To squeeze 100% of this magnet's power, you require a sufficiently solid piece of steel. The saturation phenomenon causes that on sheet metal structures (e.g., appliance housings), the magnet holds weaker. We recommend selecting the steel thickness based on the following data.

Table 5: Thermal resistance (stability) - resistance threshold

100 °C	-28.8%	1.59 kg / 3.50 lbs 1587.8 g / 15.6 N

Classic neodymiums irreversibly lose parameters past the thermal threshold. Protect against heat – excessive heat can irreversibly demagnetize this product. With every degree above norm, the neodymium's power temporarily lowers. Avoid using this magnet near heat sources higher than its operating temperature limit. Too high temperature will result in irreversible degradation of magnetism.

*Technical advisory: Thermal stability is determined by both grade, and the Permeance Coefficient Pc. Low-profile magnets (low permeance coefficient) risk losing magnetic properties under lower heat stress compared to rod magnets. The danger warning in the table indicates permanent field degradation for this specific geometry.

Two strong neodymiums attract each other from a much further distance than a magnet and sheet combination. The setup of magnet-to-magnet 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. Remember that when connecting a pair of magnets, the impact force is massive. The levitation is marginally weaker than the attraction, but still impressive.
*Flux density between like poles reaches ~0 Gs at the geometric center of the gap (caused by magnetic field nullification).
Important: Results demonstrate friction force of two matching magnets (friction ~0.15 for Ni-Ni coating).

Powerful magnet radiation poses a large risk to IT equipment as well as medical implants. These neodymiums produce a field that disrupts operation of sensitive medical devices. Notice: the unseen radiation passes through tissues and housings. Exceptional care must be exercised by people with cochlear implants and insulin pumps. Influence will be felt by: automatic timepieces, car keys, membranes, and screens. Do not place the magnet near cards, HDD media, or precise measuring instruments.

NdFeB products are prone to chipping – a violent impact against metal risks their cracking. Control the attraction moment – a neodymium left loose speeds with massive force. Impact energy can trigger coating fragments or injury to skin. Be sure to control the product during mounting so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h means shattering of the magnet. Use safety goggles when playing with large magnets.

Warning: 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. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Wall mount (shear)

*Note: On a vertical surface, the magnet retains only approx. 20-30% of its max power.

2. Plate thickness effect

*Thin metal sheet (e.g. 0.5mm PC case) significantly limits the holding force.

3. Temperature resistance

*For standard magnets, the safety limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 1.21

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 extremely powerful cylindrical magnet, composed of modern NdFeB material, which, with dimensions of Ø10x20 mm, guarantees the highest energy density. The MW 10x20 / N38 component features a tolerance of ±0.1mm and professional build quality, making it an ideal solution for the most demanding engineers and designers. As a magnetic rod with significant force (approx. 2.23 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring rapid order fulfillment. Additionally, its Ni-Cu-Ni coating effectively protects it against corrosion in standard operating conditions, ensuring 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 pull force of 21.88 N with a weight of only 11.78 g, this rod is indispensable in electronics 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 professional component. To ensure stability in industry, anaerobic resins are used, which are safe for nickel 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 (Ø10x20), 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 10 mm and height 20 mm. The key parameter here is the lifting capacity amounting to approximately 2.23 kg (force ~21.88 N), which, with such defined dimensions, proves the high power of the NdFeB material. The product has a [NiCuNi] coating, which secures it against oxidation, giving it an aesthetic, silvery shine.

This cylinder 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 diametrically if your project requires it.

Pros as well as cons of Nd₂Fe₁₄B magnets.

Benefits

In addition to their magnetic capacity, neodymium magnets provide the following advantages:

Their power is maintained, and after around ten years it drops only by ~1% (theoretically),
They retain their magnetic properties even under strong external field,
A magnet with a shiny silver surface has better aesthetics,
The surface of neodymium magnets generates a concentrated magnetic field – this is a distinguishing feature,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
Thanks to versatility in forming and the capacity to modify to specific needs,
Significant place in advanced technology sectors – they are used in computer drives, electric motors, diagnostic systems, and multitasking production systems.
Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,

Weaknesses

Problematic aspects of neodymium magnets: weaknesses and usage proposals

To avoid cracks under impact, we recommend using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
When exposed to high temperature, neodymium magnets experience 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
Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
Due to limitations in realizing threads and complicated shapes in magnets, we recommend using a housing - magnetic holder.
Health risk to health – tiny shards of magnets are risky, when accidentally swallowed, which is particularly important in the context of child health protection. It is also worth noting that tiny parts of these products are able to disrupt the diagnostic process medical when they are in the body.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Holding force characteristics

Maximum lifting force for a neodymium magnet – what contributes to it?

The lifting capacity listed is a measurement result conducted under specific, ideal conditions:

with the use of a sheet made of special test steel, ensuring maximum field concentration
with a thickness of at least 10 mm
with an ground touching surface
without the slightest air gap between the magnet and steel
under axial force direction (90-degree angle)
at temperature room level

Lifting capacity in real conditions – factors

Effective lifting capacity is affected by specific conditions, including (from priority):

Gap (between the magnet and the plate), as even a tiny distance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
Loading method – catalog parameter refers to pulling vertically. When applying parallel force, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
Plate thickness – insufficiently thick plate causes magnetic saturation, causing part of the power to be wasted into the air.
Material composition – different alloys attracts identically. High carbon content weaken the attraction effect.
Surface finish – full contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
Thermal environment – temperature increase results in weakening of force. Check the maximum operating temperature for a given model.

Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under parallel forces the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate lowers the holding force.

Precautions when working with NdFeB magnets

Hand protection

Big blocks can smash fingers in a fraction of a second. Do not place your hand between two strong magnets.

Handling rules

Handle with care. Neodymium magnets attract from a distance and snap with massive power, often faster than you can move away.

Keep away from electronics

Remember: rare earth magnets produce a field that disrupts sensitive sensors. Keep a separation from your phone, device, and GPS.

Eye protection

Despite metallic appearance, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.

No play value

These products are not intended for children. Swallowing multiple magnets can lead to them attracting across intestines, which constitutes a direct threat to life and requires immediate surgery.

Protect data

Do not bring magnets near a wallet, computer, or screen. The magnetism can destroy these devices and erase data from cards.

Combustion hazard

Drilling and cutting of neodymium magnets carries a risk of fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.

Nickel coating and allergies

It is widely known that the nickel plating (standard magnet coating) is a strong allergen. If you have an allergy, prevent touching magnets with bare hands and select coated magnets.

ICD Warning

Patients with a ICD should keep an large gap from magnets. The magnetic field can stop the operation of the implant.

Operating temperature

Regular neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. The loss of strength is permanent.
