Grip strength weakens drastically with every mm of distance. Remember that even the smallest gap (e.g., contamination, paint, veneer) noticeably diminishes the holding power. Neodymiums hold strongest at the point of direct contact; gap kills the force. Observe how flashily the load capacity fall, when the magnet does not touch tightly to the steel surface. When planning the mounting, discard unnecessary gaps.

This section presents the approximate shear load required to start the sliding of the magnet down against a vertical steel wall (assuming standard friction). This value depends on the distance between the magnet and the metal.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces
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 wall (e.g., a car body), it will maintain just about 20%-30% of its nominal power. Gravitational force as well as a low friction coefficient cause that magnets slip faster than they pop off the substrate. Planning a vertical fastening? Remember that the sliding force is significantly lower than the maximum static pull force. On a slippery surface, the element will slip down under a noticeably lighter cargo. Utilizing a rubberized pad can effectively increase the grip.

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

A too thin steel is unable to focus the full magnetic flux, which squanders power of the magnet. If you mount a strong magnet to a weak sheet, the magnetism will penetrate right through and the attraction force will be weaker. To squeeze the maximum of this magnet's potential, you require a sufficiently solid element of steel. The saturation effect means that on sheet metal structures (e.g., appliance housings), the magnet works worse. We advise picking the steel dimension based on the following data.

Standard neodymium magnets irreversibly lose parameters above the temperature limit. Protect against heat – high temperature can irreversibly demagnetize this product. With increasing heat, the neodymium's capacity momentarily decreases. Refrain from using this product in hot environments exceeding its safe range. Ignoring the limit will cause destruction of magnetic properties.

*Important note: Thermal stability is determined by both grade, and the Permeance Coefficient Pc. Thin magnets (low Pc) are more susceptible to demagnetization sooner than long magnets. The danger warning in the table signals permanent field degradation for this particular item.

Two strong neodymiums interact from a wider radius than a magnet and sheet combination. The connection of magnet-to-magnet creates a more powerful interaction and a further horizon of operation. Designing a powerful holder? Use a pair of magnets instead of a neodymium and a striker plate. Exercise caution that when attracting two neodymiums, the pinch force is huge. The levitation is a bit weaker than the attraction, but still large.
*Field value for N-N configuration drops to ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
Note: Estimates demonstrate friction force of dual matching magnets (friction ~0.15 for Ni-Ni coating).

Extremely neodym field poses a serious hazard to electronic devices and pacemakers. These magnets produce a field that prevents correct functioning of digital equipment. Be aware: the invisible magnetic field passes through tissues and plastic. Special caution must be taken by people with cochlear implants and drug dispensers. The risk also applies to: automatic timepieces, car keys, speakers, and displays. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

NdFeB products are prone to chipping – a violent impact against metal causes immediate chipping. Pay attention to connection velocity – a magnet released freely becomes dangerous. Striking energy can destroy the magnet or injury to skin. Be sure to control the product during mounting so it doesn't hit with great force against the metal. A collision at high speed almost guarantees destruction of the neodymium. Wear eye protection when playing with powerful specimens.

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. However, remember the water resistance when pulling the rope quickly.

1. Shear force

*Caution: On a vertical wall, the magnet retains merely ~20% of its perpendicular strength.

2. Efficiency vs thickness

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

3. Thermal stability

*For N38 grade, the safety 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.

This product is an exceptionally strong cylindrical magnet, manufactured from durable NdFeB material, which, at dimensions of Ø8x5 mm, guarantees the highest energy density. The MW 8x5 / N38 component is characterized by high dimensional repeatability and industrial build quality, making it an excellent solution for professional engineers and designers. As a magnetic rod with significant force (approx. 2.17 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring lightning-fast order fulfillment. Furthermore, its Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

This model is ideal for building electric motors, advanced Hall effect sensors, and efficient magnetic separators, where field concentration on a small surface counts. Thanks to the pull force 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 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 long-term durability 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 frequently chosen standard for industrial neodymium magnets, offering an optimal price-to-power ratio and high resistance to demagnetization. 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 warehouse.

The presented product is a neodymium magnet with precisely defined parameters: diameter 8 mm and height 5 mm. The key parameter here is the holding force 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 secures it against external factors, giving it an aesthetic, silvery shine.

This cylinder is magnetized axially (along the height of 5 mm), which means that the N and S poles are located on the flat, circular surfaces. 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 and cons of neodymium magnets.

Advantages

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

They do not lose power, even over approximately 10 years – the decrease in power is only ~1% (according to tests),
Magnets very well protect themselves against loss of magnetization caused by foreign field sources,
A magnet with a shiny gold surface is more attractive,
They feature high magnetic induction at the operating surface, which affects their effectiveness,
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...
Possibility of detailed forming and modifying to precise requirements,
Significant place in modern technologies – they serve a role in hard drives, electromotive mechanisms, diagnostic systems, and modern systems.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which enables their usage in small systems

Weaknesses

Disadvantages of NdFeB magnets:

They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their power 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
They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
Due to limitations in producing threads and complicated shapes in magnets, we recommend using a housing - magnetic mount.
Potential hazard related to microscopic parts of magnets are risky, if swallowed, which gains importance in the context of child health protection. It is also worth noting that small components of these magnets are able to be problematic in diagnostics medical after entering the body.
With large orders the cost of neodymium magnets can be a barrier,

Pull force analysis

Best holding force of the magnet in ideal parameters – what it depends on?

The specified lifting capacity refers to the maximum value, obtained under optimal environment, namely:

with the application of a sheet made of special test steel, ensuring full magnetic saturation
possessing a thickness of at least 10 mm to avoid saturation
with a plane free of scratches
without any insulating layer between the magnet and steel
for force applied at a right angle (pull-off, not shear)
at temperature approx. 20 degrees Celsius

Key elements affecting lifting force

It is worth knowing that the magnet holding will differ influenced by the following factors, starting with the most relevant:

Clearance – the presence of any layer (rust, dirt, air) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
Load vector – maximum parameter is available only during pulling at a 90° angle. The force required to slide of the magnet along the plate is typically several times lower (approx. 1/5 of the lifting capacity).
Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of generating force.
Steel grade – the best choice is high-permeability steel. Stainless steels may generate lower lifting capacity.
Plate texture – ground elements guarantee perfect abutment, which increases force. Uneven metal reduce efficiency.
Thermal factor – hot environment weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.

Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the load capacity is reduced by as much as 75%. In addition, even a small distance between the magnet and the plate lowers the lifting capacity.

Warnings

Caution required

Before use, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.

Finger safety

Mind your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, destroying everything in their path. Be careful!

Nickel allergy

Some people have a hypersensitivity to Ni, which is the standard coating for NdFeB magnets. Extended handling might lead to a rash. We suggest use protective gloves.

GPS and phone interference

Navigation devices and smartphones are extremely sensitive to magnetism. Direct contact with a powerful NdFeB magnet can permanently damage the sensors in your phone.

Demagnetization risk

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

Magnetic media

Very strong magnetic fields can erase data on credit cards, HDDs, and storage devices. Maintain a gap of at least 10 cm.

Pacemakers

For implant holders: Powerful magnets disrupt electronics. Maintain minimum 30 cm distance or request help to handle the magnets.

Dust is flammable

Drilling and cutting of NdFeB material poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.

Magnet fragility

Watch out for shards. Magnets can fracture upon violent connection, ejecting shards into the air. Eye protection is mandatory.

No play value

These products are not toys. Eating several magnets can lead to them connecting inside the digestive tract, which poses a severe health hazard and necessitates urgent medical intervention.
