Physical modeling of the magnet - data

Presented information are the outcome of a mathematical calculation. Results are based on models for the material Nd₂Fe₁₄B. Real-world performance may differ. Treat these data as a reference point when designing systems.

Grip strength drops sharply with every subsequent millimeter of spacing. Keep in mind that even a very thin break (e.g., contamination, varnish, dust) noticeably diminishes the holding power. Magnets hold most effectively during direct contact; air break weakens the force. Notice how flashily the pull force plummet, when the magnet does not adhere flatly to the metal substrate. When designing the mounting, avoid additional spacers.

The following data shows the approximate force needed to initiate the sliding of the magnet vertically on a vertical steel wall (considering standard friction). This value is relative to the air gap between the magnet and the surface.

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 mounting a magnet on a upright surface (e.g., a fridge), it will maintain only about 1/5 of its maximum pull force. Gravitational force as well as a low friction coefficient cause that products slide down easier than they pull off. Planning a hanger? Note that the sliding force is significantly lower than the maximum static pull force. On a painted metal, the holder will slip down under a significantly smaller load. Using a rubber coating can effectively raise the stability.

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

A too thin steel cannot take in the full magnetic flux, which wastes potential of the holder. Should you mount a strong magnet to a too thin substrate, the magnetism will pass right through and the pull force will drop sharply. To squeeze the maximum of this neodymium's power, you require a sufficiently solid element of metal. The saturation effect means that on delicate walls (e.g., car bodies), the magnet shows lower pull force. We recommend selecting the steel thickness from these parameters.

Standard neodymium magnets change their properties parameters above the temperature limit. Avoid high temperatures – high temperature can irreversibly damage this magnet. As the temperature rises, the neodymium's power temporarily drops. Avoid using this product in hot environments exceeding its operating temperature limit. Exceeding the critical threshold will lead to destruction of magnetic properties.

*Engineering note: Heat tolerance is determined by both grade, and the Permeance Coefficient Pc. Low-profile magnets (low permeance coefficient) are more susceptible to demagnetization under lower heat stress than taller cylinders. Warning indicator in the table points to a risk of irreversible loss for this specific geometry.

Two magnets interact from a significantly greater distance than a neodymium and metal setup. Such a system of two magnets generates a stronger field and a wider radius of operation. Planning to create a solid fastener? Utilize two neodymiums instead of a neodymium and a steel. Remember that when bringing together two magnets, the collision energy is huge. The levitation is marginally weaker than the attraction, but still large.
*The magnetic induction in repulsion mode reaches ~0 Gs at the midpoint of the gap (due to field cancellation).
* Calculations show sliding force of two identical neodymium magnets (friction ~0.15 for Ni-Ni coating).

Table 7: Hazards (electronics) - precautionary measures
MW 5x2 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	2.5 cm

Extremely neodym field is a large risk to electronic devices as well as pacemakers. These neodymiums generate a flux that disrupts operation of sensitive medical devices. Notice: the invisible magnetic field passes through tissues and plastic. Special caution must be exercised by people with hearing aids and drug dispensers. The risk also applies to: automatic timepieces, remotes, membranes, and screens. Do not place the magnet near cards, hard drives, or precise measuring instruments.

NdFeB products are prone to chipping – a strong collision with metal risks their cracking. Control the attraction moment – a magnet released freely becomes dangerous. Striking energy can destroy the magnet or painful pinches to fingers. Always hold the magnet during mounting so it doesn't hit with great force against the steel surface. A contact at a velocity of dozens of km/h ends with a crack of the magnet. Wear eye protection when working with powerful specimens.

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. Shear force

*Note: On a vertical wall, the magnet holds only ~20% of its perpendicular strength.

2. Efficiency vs thickness

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

3. Heat tolerance

*For N38 grade, the critical limit is 80°C.

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

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

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, manufactured from modern NdFeB material, which, at dimensions of Ø5x2 mm, guarantees maximum efficiency. This specific item boasts high dimensional repeatability and professional build quality, making it an excellent solution for the most demanding engineers and designers. As a magnetic rod with impressive force (approx. 0.70 kg), this product is in stock from our European logistics center, ensuring quick order fulfillment. Moreover, its Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

This model is perfect for building electric motors, advanced Hall effect sensors, and efficient magnetic separators, where maximum induction on a small surface counts. Thanks to the high power of 6.83 N with a weight of only 0.29 g, this rod 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 immediate cracking of this professional component. To ensure long-term durability in industry, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.

Magnets NdFeB grade N38 are strong enough for 90% of applications in automation and machine building, where excessive miniaturization with maximum force is not required. If you need the strongest 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 holding force amounting to approximately 0.70 kg (force ~6.83 N), which, with such defined dimensions, proves the high grade of the NdFeB material. The product has a [NiCuNi] coating, which secures it 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 5 mm. Such an arrangement is most desirable 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 diametrically if your project requires it.

Strengths and weaknesses of rare earth magnets.

Pros

Besides their tremendous strength, neodymium magnets offer the following advantages:

They have constant strength, and over nearly ten years their performance decreases symbolically – ~1% (in testing),
Magnets very well defend themselves against loss of magnetization caused by external fields,
A magnet with a shiny gold surface is more attractive,
The surface of neodymium magnets generates a strong magnetic field – this is a key feature,
Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
Considering the ability of accurate shaping and adaptation to specialized projects, neodymium magnets can be produced in a variety of forms and dimensions, which makes them more universal,
Wide application in modern technologies – they are used in HDD drives, electric motors, advanced medical instruments, and complex engineering applications.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Limitations

Disadvantages of neodymium magnets:

To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
Due to limitations in producing threads and complex shapes in magnets, we propose using cover - magnetic holder.
Potential hazard related to microscopic parts of magnets pose a threat, when accidentally swallowed, which becomes key in the context of child health protection. Additionally, tiny parts of these products can complicate diagnosis medical when they are in the body.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities

Lifting parameters

Optimal lifting capacity of a neodymium magnet – what affects it?

Holding force of 0.70 kg is a theoretical maximum value executed under standard conditions:

on a block made of mild steel, optimally conducting the magnetic field
whose transverse dimension equals approx. 10 mm
with an ideally smooth contact surface
without the slightest air gap between the magnet and steel
for force applied at a right angle (in the magnet axis)
at room temperature

Practical lifting capacity: influencing factors

In real-world applications, the actual holding force depends on a number of factors, presented from the most important:

Distance (betwixt the magnet and the metal), because even a microscopic distance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to varnish, rust or dirt).
Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
Chemical composition of the base – low-carbon steel attracts best. Alloy steels lower magnetic permeability and holding force.
Surface finish – ideal contact is possible only on polished steel. Any scratches and bumps create air cushions, reducing force.
Heat – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).

Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under shearing force the load capacity is reduced by as much as 5 times. Moreover, even a minimal clearance between the magnet and the plate reduces the lifting capacity.

H&S for magnets

Combustion hazard

Machining of neodymium magnets carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.

Bone fractures

Danger of trauma: The attraction force is so immense that it can cause blood blisters, pinching, and even bone fractures. Use thick gloves.

This is not a toy

NdFeB magnets are not suitable for play. Accidental ingestion of multiple magnets can lead to them attracting across intestines, which constitutes a direct threat to life and requires immediate surgery.

Permanent damage

Regular neodymium magnets (N-type) lose power when the temperature goes above 80°C. This process is irreversible.

Medical interference

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

Nickel coating and allergies

Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If redness happens, immediately stop working with magnets and wear gloves.

GPS and phone interference

Note: rare earth magnets produce a field that confuses precision electronics. Keep a safe distance from your phone, device, and GPS.

Powerful field

Handle magnets with awareness. Their immense force can shock even experienced users. Plan your moves and respect their force.

Material brittleness

Despite the nickel coating, the material is brittle and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.

Keep away from computers

Do not bring magnets close to a wallet, laptop, or screen. The magnetic field can destroy these devices and wipe information from cards.
