Grip strength weakens drastically with every subsequent millimeter of distance. Remember that even a microscopic distance (e.g., dirt, paint, rust) significantly reduces the pull force. Neodymiums operate strongest in perfect adhesion; gap drastically cuts the power. See how quickly the load capacity plummet, when the product does not touch directly to the metal substrate. When designing the assembly, avoid unnecessary gaps.

The table below defines the approximate holding capacity necessary to start the downward movement of the magnet vertically against a vertical steel plate (assuming typical friction coefficient). This value varies with the distance between the magnet and the metal.

Table 3: Vertical assembly (shearing) - vertical pull
MW 5x4 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.25 kg / 0.56 pounds 252.0 g / 2.5 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.17 kg / 0.37 pounds 168.0 g / 1.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.08 kg / 0.19 pounds 84.0 g / 0.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.42 kg / 0.93 pounds 420.0 g / 4.1 N

When mounting a holder on a upright plane (e.g., a board), it will only hold barely about 20%-30% of its nominal power. Gravity as well as a low friction coefficient cause that magnets slip faster than they detach. Want to create a vertical fastening? Note that the sliding force is noticeably lower than the maximum static pull force. On a smooth steel, the element will slide down under a much lighter cargo. Application of an anti-slip pad can effectively increase the grip.

12 mm	100%	0.84 kg / 1.85 pounds 840.0 g / 8.2 N

A too thin steel is unable to absorb the full magnetic flux, which squanders power of the holder. Should you attach a powerful product to a too thin substrate, the field will penetrate right through and the holding will be smaller. To achieve the maximum of this magnet's power, you need a suitably thick element of steel. The saturation phenomenon means that on thin elements (e.g., car bodies), the product works worse. We advise picking the steel cross-section based on the following data.

Table 5: Working in heat (material behavior) - resistance threshold
MW 5x4 / N38

40 °C	-2.2%	0.82 kg / 1.81 pounds 821.5 g / 8.1 N	OK

100 °C	-28.8%	0.60 kg / 1.32 pounds 598.1 g / 5.9 N

Ordinary NdFeB products change their properties power after exceeding the maximum temperature. Protect against heat – excessive heat can irreversibly demagnetize this product. As the temperature rises, the neodymium's force momentarily decreases. Refrain from using this product close to heaters higher than its operating temperature limit. Exceeding the critical threshold will lead to permanent loss of magnetism.

*Engineering note: Temperature resistance depends not only on the material grade, and the Permeance Coefficient Pc. Flat magnets (pancake types) may lose charge permanently at lower temperatures compared to rod magnets. Warning indicator in the table indicates permanent field degradation for this particular item.

Two magnetic products attract each other from a wider radius than a neodymium and metal setup. The connection of magnet-to-magnet creates a more powerful interaction and a larger range of performance. Designing a strong closure? Apply two magnets instead of one magnet and a striker plate. Exercise caution that when bringing together two magnets, the collision energy is extreme. The levitation is slightly lower than the attraction, but still large.
*The magnetic induction in repulsion mode reaches ~0 Gs at the midpoint of the gap (caused by magnetic field nullification).
Attention: Results refer to sliding force of two identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

A strong magnetic field poses a serious hazard to electronic devices as well as medical implants. These magnets produce a field that destroys function of sensitive medical devices. Notice: the invisible magnetic field penetrates the body and housings. Exceptional care must be exercised by people with hearing aids and drug dispensers. Influence will be felt by: mechanical watches, remotes, membranes, and screens. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

Neodymium magnets are delicate – a strong collision with metal can result in shattering. Watch the impact speed – a magnet released freely turns into a projectile. Impact energy can destroy the magnet or painful pinches to skin. Hold the magnet firmly during bringing near metal so it doesn't hit violently against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the neodymium. Wear eye protection when playing with large magnets.

Warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

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. Sliding resistance

*Caution: On a vertical wall, the magnet retains only a fraction of its perpendicular strength.

2. Steel saturation

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

3. Heat tolerance

*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) = 0.79

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 presented product is an incredibly powerful rod magnet, made from advanced NdFeB material, which, at dimensions of Ø5x4 mm, guarantees the highest energy density. This specific item boasts high dimensional repeatability and professional build quality, making it an ideal solution for the most demanding engineers and designers. As a magnetic rod with impressive force (approx. 0.84 kg), this product is available off-the-shelf from our European logistics center, ensuring lightning-fast order fulfillment. Additionally, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.

It successfully proves itself in modeling, advanced robotics, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 8.24 N with a weight of only 0.59 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 chipping the coating of this professional component. To ensure stability in automation, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.

Magnets N38 are suitable for the majority of applications in automation and machine building, where extreme miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø5x4), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.

This model is characterized by dimensions Ø5x4 mm, which, at a weight of 0.59 g, makes it an element with impressive magnetic energy density. The key parameter here is the holding force amounting to approximately 0.84 kg (force ~8.24 N), which, with such defined 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 rod magnet is magnetized axially (along the height of 4 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 rare earth magnets.

Benefits

Besides their durability, neodymium magnets are valued for these benefits:

Their magnetic field remains stable, and after approximately ten years it decreases only by ~1% (according to research),
Neodymium magnets are highly resistant to demagnetization caused by external field sources,
Thanks to the glossy finish, the layer of Ni-Cu-Ni, gold, or silver gives an elegant appearance,
Neodymium magnets deliver maximum magnetic induction on a small area, which allows for strong attraction,
Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures reaching 230°C and above...
Possibility of exact forming as well as adjusting to complex applications,
Versatile presence in future technologies – they serve a role in magnetic memories, electromotive mechanisms, advanced medical instruments, and other advanced devices.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Weaknesses

Disadvantages of neodymium magnets:

They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also increases its resistance to damage
Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
We suggest cover - magnetic mount, due to difficulties in realizing nuts inside the magnet and complex forms.
Potential hazard related to microscopic parts of magnets can be dangerous, in case of ingestion, which becomes key in the aspect of protecting the youngest. It is also worth noting that small elements of these products are able to be problematic in diagnostics medical when they are in the body.
High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities

Lifting parameters

Optimal lifting capacity of a neodymium magnet – what it depends on?

Information about lifting capacity was defined for ideal contact conditions, including:

using a plate made of mild steel, acting as a magnetic yoke
with a thickness minimum 10 mm
with a surface perfectly flat
under conditions of ideal adhesion (surface-to-surface)
under perpendicular force vector (90-degree angle)
at temperature approx. 20 degrees Celsius

Lifting capacity in practice – influencing factors

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

Gap (between the magnet and the plate), because even a tiny distance (e.g. 0.5 mm) results in a reduction in force by up to 50% (this also applies to paint, corrosion or debris).
Load vector – maximum parameter is reached only during perpendicular pulling. The resistance to sliding of the magnet along the plate is standardly several times lower (approx. 1/5 of the lifting capacity).
Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
Chemical composition of the base – low-carbon steel attracts best. Alloy admixtures lower magnetic permeability and lifting capacity.
Smoothness – full contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
Operating temperature – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).

Lifting capacity was measured with the use of a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Additionally, even a slight gap between the magnet’s surface and the plate lowers the lifting capacity.

Precautions when working with neodymium magnets

Heat sensitivity

Do not overheat. Neodymium magnets are sensitive to heat. If you require operation above 80°C, inquire about special high-temperature series (H, SH, UH).

Do not underestimate power

Exercise caution. Neodymium magnets attract from a long distance and snap with huge force, often quicker than you can react.

Protective goggles

Despite metallic appearance, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.

Sensitization to coating

Allergy Notice: The Ni-Cu-Ni coating contains nickel. If skin irritation happens, cease handling magnets and use protective gear.

Electronic devices

Equipment safety: Neodymium magnets can ruin payment cards and delicate electronics (heart implants, medical aids, mechanical watches).

Fire warning

Drilling and cutting of neodymium magnets poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.

Keep away from children

Product intended for adults. Small elements pose a choking risk, leading to serious injuries. Store away from children and animals.

Threat to navigation

Be aware: rare earth magnets produce a field that interferes with sensitive sensors. Maintain a safe distance from your mobile, tablet, and navigation systems.

Implant safety

Individuals with a pacemaker must maintain an safe separation from magnets. The magnetism can interfere with the functioning of the implant.

Bodily injuries

Mind your fingers. Two powerful magnets will join instantly with a force of several hundred kilograms, destroying anything in their path. Exercise extreme caution!
