Pulling power weakens significantly with every subsequent millimeter of distance. Note that even a very thin break (e.g., dirt, varnish, dust) significantly weakens the grip. Neodymiums operate optimally in perfect adhesion; gap kills the power. See how flashily the parameters plummet, when the magnet does not touch tightly to the metal substrate. When designing the mounting, avoid redundant distances.

The table below shows the estimated shear load needed to cause the downward movement of the magnet vertically on a vertical steel plate (assuming standard friction). This parameter is relative to the distance between the magnet and the metal.

Table 3: Vertical assembly (sliding) - vertical pull
MW 4x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.14 kg / 0.30 pounds 138.0 g / 1.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.09 kg / 0.20 pounds 92.0 g / 0.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.05 kg / 0.10 pounds 46.0 g / 0.5 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.23 kg / 0.51 pounds 230.0 g / 2.3 N

When mounting a magnet on a upright surface (e.g., a car body), it will only hold just approx. 20%-30% of its nominal power. Gravitational force and a weak degree of grip mean that products slip easier than they detach. Planning a hanger? Consider that the shear force is much weaker than the perpendicular breakaway force. On a smooth steel, the holder will give way down under a noticeably lighter load. Application of an anti-slip coating can drastically raise the stability.

12 mm	100%	0.46 kg / 1.01 pounds 460.0 g / 4.5 N

A too thin steel is unable to focus the entire magnetic field, which squanders power of the magnet. Should you attach a powerful product to a thin surface, the flux will penetrate right through and the pull force will drop sharply. To utilize 100% of this neodymium's power, you need a suitably thick piece of steel. The saturation effect causes that on thin elements (e.g., car bodies), the product holds weaker. We advise picking the steel cross-section according to the table below.

Classic neodymiums lose strength past the thermal threshold. Watch out for overheating – excessive heat can irreversibly destroy this magnet. With every degree above norm, the magnet's capacity momentarily decreases. Do not use this product in hot environments higher than its operating temperature limit. Exceeding the critical threshold will cause irreversible degradation of magnetism.

*Important note: Heat tolerance depends not only on the material grade, as well as the dimension ratios. Thin magnets (pancake types) may lose charge permanently sooner than taller cylinders. Red status in the table points to permanent field degradation for this specific geometry.

Two strong neodymiums attract each other from a much further distance than a magnet and steel setup. The setup of two magnets creates a more powerful interaction and a larger range of action. Designing a solid fastener? Use a pair of magnets instead of a neodymium and a striker plate. Remember that when attracting two neodymiums, the collision energy is extreme. The levitation is slightly lower than the connection force, but still impressive.
*Field value for N-N configuration reaches ~0 Gs in the exact middle of the gap (due to field cancellation).
* Results apply to sliding force of dual same neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

Extremely neodym field poses a serious hazard to IT equipment as well as medical implants. These neodymiums generate a field that destroys function of sensitive medical devices. Remember: the invisible magnetic field acts through matter and glass. Special caution must be exercised by people with cochlear implants and insulin pumps. The risk also applies to: automatic timepieces, car keys, speakers, and displays. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

NdFeB products are delicate – a strong collision with metal can result in shattering. Pay attention to connection velocity – a magnet released freely becomes dangerous. Kinetic force can trigger coating fragments or injury to skin. Be sure to control the product during bringing near metal so it doesn't hit violently against the metal. A collision at high speed ends with a crack of the neodymium. Use safety goggles when playing with powerful specimens.

Rust risk: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

The magnetic field penetrates through water without any losses. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Wall mount (shear)

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

2. Efficiency vs thickness

*Thin metal sheet (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) = 1.00

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 extremely powerful cylindrical magnet, composed of advanced NdFeB material, which, at dimensions of Ø4x5 mm, guarantees optimal power. This specific item is characterized by high dimensional repeatability and industrial build quality, making it an ideal solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 0.46 kg), this product is in stock from our European logistics center, ensuring quick order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is ideal for building electric motors, advanced Hall effect sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the high power of 4.48 N with a weight of only 0.47 g, this cylindrical magnet is indispensable in electronics and wherever every gram matters.

Since our magnets have a very precise dimensions, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 4.1 mm) using epoxy glues. 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.

Magnets N38 are suitable for the majority of applications in automation and machine building, where excessive miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø4x5), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

The presented product is a neodymium magnet with precisely defined parameters: diameter 4 mm and height 5 mm. The key parameter here is the holding force amounting to approximately 0.46 kg (force ~4.48 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. 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.

Pros as well as cons of Nd₂Fe₁₄B magnets.

Benefits

In addition to their long-term stability, neodymium magnets provide the following advantages:

They retain attractive force for nearly 10 years – the loss is just ~1% (according to analyses),
Neodymium magnets remain extremely resistant to demagnetization caused by magnetic disturbances,
A magnet with a smooth nickel surface looks better,
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 are able to act (depending on the form) even at a temperature of 230°C or more...
Possibility of exact forming and adapting to precise requirements,
Versatile presence in advanced technology sectors – they are commonly used in mass storage devices, electromotive mechanisms, medical devices, also complex engineering applications.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which enables their usage in small systems

Limitations

Problematic aspects of neodymium magnets: tips and applications.

To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
Limited ability of making threads in the magnet and complex shapes - recommended is a housing - mounting mechanism.
Possible danger to health – tiny shards of magnets are risky, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. 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.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities

Lifting parameters

Magnetic strength at its maximum – what contributes to it?

Breakaway force was determined for ideal contact conditions, including:

with the contact of a sheet made of low-carbon steel, ensuring maximum field concentration
possessing a thickness of min. 10 mm to ensure full flux closure
with a plane perfectly flat
with direct contact (without coatings)
during detachment in a direction perpendicular to the mounting surface
at ambient temperature room level

Determinants of practical lifting force of a magnet

Effective lifting capacity impacted by specific conditions, mainly (from most important):

Air gap (betwixt the magnet and the metal), because even a microscopic distance (e.g. 0.5 mm) results in a reduction in force by up to 50% (this also applies to varnish, rust or dirt).
Loading method – catalog parameter refers to pulling vertically. When attempting to slide, the magnet holds much less (typically approx. 20-30% of maximum force).
Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
Material type – ideal substrate is pure iron steel. Hardened steels may generate lower lifting capacity.
Surface quality – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Unevenness acts like micro-gaps.
Thermal factor – hot environment weakens pulling force. Too high temperature can permanently damage the magnet.

Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under perpendicular forces, in contrast under parallel forces the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate reduces the holding force.

Safe handling of NdFeB magnets

Product not for children

Always keep magnets away from children. Choking hazard is significant, and the effects of magnets clamping inside the body are life-threatening.

Fire warning

Combustion risk: Rare earth powder is explosive. Do not process magnets without safety gear as this may cause fire.

Metal Allergy

Allergy Notice: The Ni-Cu-Ni coating contains nickel. If an allergic reaction happens, cease working with magnets and use protective gear.

Electronic devices

Device Safety: Neodymium magnets can damage payment cards and sensitive devices (heart implants, medical aids, timepieces).

Compass and GPS

Navigation devices and smartphones are extremely susceptible to magnetic fields. Close proximity with a strong magnet can ruin the internal compass in your phone.

Finger safety

Danger of trauma: The pulling power is so great that it can cause hematomas, crushing, and broken bones. Use thick gloves.

Respect the power

Handle magnets with awareness. Their powerful strength can surprise even professionals. Be vigilant and respect their power.

Maximum temperature

Standard neodymium magnets (N-type) lose magnetization when the temperature goes above 80°C. The loss of strength is permanent.

Warning for heart patients

Health Alert: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.

Fragile material

Beware of splinters. Magnets can fracture upon violent connection, ejecting shards into the air. Wear goggles.

Caution! Learn more about hazards in the article: Safety of working with magnets.
