Pulling power decreases sharply per each millimeter of gap. Keep in mind that even a very thin break (e.g., contamination, paint, veneer) significantly diminishes the holding power. Magnets hold most effectively in perfect adhesion; gap weakens the force. See how quickly the load capacity plummet, when the magnet does not touch directly to the metal substrate. When planning the arrangement, discard additional spacers.

The following data shows the estimated holding capacity necessary to start the downward movement of the magnet vertically against a upright steel wall (assuming typical friction). This parameter is relative to the separation distance between the magnet and the surface.

Table 3: Wall mounting (sliding) - vertical pull
MW 8x4 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.61 kg / 1.35 pounds 612.0 g / 6.0 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.41 kg / 0.90 pounds 408.0 g / 4.0 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.20 kg / 0.45 pounds 204.0 g / 2.0 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.02 kg / 2.25 pounds 1020.0 g / 10.0 N

When placing a holder on a upright wall (e.g., a car body), it will only hold barely approx. 20%-30% of its nominal power. Gravity as well as a low friction coefficient influence the fact that products slip faster than they pop off the substrate. Planning a wall mount? Remember that the sliding force is significantly lower than the perpendicular breakaway force. On a painted metal, the magnet will give way down under a much lighter cargo. Utilizing a rubberized layer can drastically improve the result.

12 mm	100%	2.04 kg / 4.50 pounds 2040.0 g / 20.0 N

A thin sheet is not enough to take in the full magnetic flux, which squanders power of the holder. Should you install a neodymium to a weak sheet, the flux will pass right through and the attraction force will be weaker. To squeeze the maximum of this neodymium's power, you need a suitably thick piece of steel. The saturation phenomenon causes that on sheet metal structures (e.g., car bodies), the product works worse. We advise picking the steel thickness from these parameters.

Classic neodymiums change their properties power above the temperature limit. Protect against heat – excessive heat can permanently destroy this product. With every degree above norm, the neodymium's power temporarily decreases. Avoid using this magnet in hot environments exceeding its safe range. Too high temperature will cause permanent loss of magnetism.

*Engineering note: Temperature resistance is determined by both grade, as well as the dimension ratios. Thin magnets (pancake types) may lose charge permanently under lower heat stress compared to rod magnets. Warning indicator in the table signals permanent field degradation for this specific geometry.

Two magnets attract each other from a much further distance than a magnet and sheet combination. Such a system of two magnets produces a massive flux and a larger range of performance. Planning to create a solid fastener? Utilize two neodymiums instead of one magnet and a striker plate. Exercise caution that when attracting two neodymiums, the impact force is huge. The levitation is a bit weaker than the attraction, but still large.
*The magnetic induction between like poles is approximately ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
Note: Calculations refer to sliding force of a pair of matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

A strong magnetic field poses a real danger to IT equipment as well as medical implants. These magnets produce a field that destroys function of sensitive medical devices. Remember: the invisible magnetic field passes through tissues and glass. Increased vigilance must be exercised by people with hearing aids and insulin pumps. Also at risk are: mechanical watches, remotes, membranes, and displays. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

Magnetic elements are very brittle – a collision with steel causes immediate chipping. Control the attraction moment – a magnet released freely becomes dangerous. Kinetic force can cause material chips or dangerous crushing to skin. Always hold the magnet during installation so it doesn't hit violently against the steel surface. A collision at high speed almost guarantees destruction of the neodymium. Wear eye protection when playing with large magnets.

1. Vertical hold

*Caution: On a vertical wall, the magnet holds merely a fraction of its max power.

2. Steel thickness impact

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

3. Heat tolerance

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.59

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.

The offered product is an exceptionally strong cylindrical magnet, manufactured from modern NdFeB material, which, at dimensions of Ø8x4 mm, guarantees optimal power. This specific item is characterized by an accuracy of ±0.1mm and industrial build quality, making it an excellent solution for the most demanding engineers and designers. As a magnetic rod with impressive force (approx. 2.04 kg), this product is in stock from our warehouse in Poland, ensuring lightning-fast order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

It finds application in modeling, advanced robotics, and broadly understood industry, serving as a fastening or actuating element. Thanks to the high power of 20.00 N with a weight of only 1.51 g, this cylindrical magnet is indispensable in miniature devices and wherever low weight is crucial.

Due to the brittleness of the NdFeB material, you must not use force-fitting (so-called press-fit), as this risks chipping the coating of this precision 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 high repeatability of the connection.

Grade N38 is the most popular 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 (Ø8x4), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.

This model is characterized by dimensions Ø8x4 mm, which, at a weight of 1.51 g, makes it an element with high magnetic energy density. The value of 20.00 N means that the magnet is capable of holding a weight many times exceeding its own mass of 1.51 g. The product has a [NiCuNi] coating, which secures it 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 8 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.

Strengths and weaknesses of rare earth magnets.

Benefits

Besides their immense pulling force, neodymium magnets offer the following advantages:

They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (in laboratory conditions),
Neodymium magnets remain remarkably resistant to demagnetization caused by external interference,
The use of an shiny coating of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
The surface of neodymium magnets generates a intense magnetic field – this is a key feature,
Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
Considering the ability of accurate shaping and adaptation to custom requirements, magnetic components can be modeled in a variety of shapes and sizes, which increases their versatility,
Key role in advanced technology sectors – they find application in computer drives, electromotive mechanisms, medical devices, and technologically advanced constructions.
Thanks to their power density, small magnets offer high operating force, in miniature format,

Cons

Disadvantages of neodymium magnets:

At very strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
Neodymium magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (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 extremely resistant to heat
They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
Due to limitations in producing nuts and complicated forms in magnets, we recommend using a housing - magnetic mount.
Health risk resulting from small fragments of magnets pose a threat, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Additionally, small elements of these devices are able to complicate diagnosis medical after entering the body.
Due to expensive raw materials, their price is higher than average,

Holding force characteristics

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

Breakaway force was defined for optimal configuration, taking into account:

with the application of a sheet made of low-carbon steel, guaranteeing maximum field concentration
whose thickness reaches at least 10 mm
characterized by smoothness
without the slightest insulating layer between the magnet and steel
under vertical force direction (90-degree angle)
at standard ambient temperature

Practical lifting capacity: influencing factors

Please note that the application force will differ influenced by elements below, starting with the most relevant:

Distance (betwixt the magnet and the metal), because even a very small clearance (e.g. 0.5 mm) leads to a decrease in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
Force direction – catalog parameter refers to detachment vertically. When applying parallel force, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
Chemical composition of the base – low-carbon steel attracts best. Higher carbon content decrease magnetic permeability and lifting capacity.
Smoothness – ideal contact is obtained only on smooth steel. Rough texture reduce the real contact area, reducing force.
Thermal factor – hot environment weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the holding force is lower. Additionally, even a minimal clearance between the magnet’s surface and the plate lowers the load capacity.

Warnings

Maximum temperature

Keep cool. NdFeB magnets are sensitive to heat. If you need resistance above 80°C, ask us about special high-temperature series (H, SH, UH).

Keep away from electronics

Navigation devices and smartphones are extremely susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can permanently damage the internal compass in your phone.

Powerful field

Use magnets with awareness. Their powerful strength can shock even experienced users. Be vigilant and do not underestimate their force.

Dust is flammable

Combustion risk: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this may cause fire.

Avoid contact if allergic

Medical facts indicate that the nickel plating (the usual finish) is a strong allergen. If your skin reacts to metals, avoid touching magnets with bare hands or select coated magnets.

Protect data

Avoid bringing magnets near a purse, computer, or screen. The magnetic field can permanently damage these devices and erase data from cards.

Beware of splinters

NdFeB magnets are ceramic materials, which means they are very brittle. Impact of two magnets leads to them shattering into shards.

Hand protection

Large magnets can crush fingers in a fraction of a second. Do not put your hand betwixt two strong magnets.

ICD Warning

Life threat: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.

No play value

Strictly keep magnets away from children. Risk of swallowing is significant, and the consequences of magnets clamping inside the body are tragic.
