Pulling power drops sharply with every subsequent millimeter of distance. Note that even a microscopic distance (e.g., dirt, paint, rust) noticeably weakens the grip. Magnets operate strongest in perfect adhesion; air break drastically cuts the power. Notice how quickly the pull force drop, when the magnet does not adhere tightly to the steel surface. When calculating the arrangement, eliminate redundant distances.

The following data presents the estimated weight limit sufficient to start the downward movement of the magnet vertically against a upright metal surface (considering typical friction). This parameter is relative to the separation distance between the magnet and the surface.

Table 3: Vertical assembly (shearing) - vertical pull
MW 5x30 / 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 135.0 g / 1.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.09 kg / 0.20 pounds 90.0 g / 0.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.05 kg / 0.10 pounds 45.0 g / 0.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.23 kg / 0.50 pounds 225.0 g / 2.2 N

When placing a element on a upright plane (e.g., a car body), it you can count on barely about 20%-30% of its nominal power. Gravity and a weak degree of grip mean that magnets move down faster than they detach. Designing a wall mount? Remember that the sliding force is significantly lower than the maximum static pull force. On a slippery surface, the magnet will slide down under a noticeably lighter cargo. Application of an anti-slip pad can significantly improve the result.

12 mm	100%	0.45 kg / 0.99 pounds 450.0 g / 4.4 N

A thin metal plate is unable to conduct the full magnetic flux, which squanders power of the holder. Should you install a neodymium to a weak sheet, the field will pass right through and the pull force will drop sharply. To achieve the maximum of this magnet's power, you need a suitably thick element of metal. The saturation effect causes that on sheet metal structures (e.g., thin profiles), the product works worse. We recommend selecting the steel dimension based on the following data.

Ordinary NdFeB products irreversibly lose strength above the temperature limit. Watch out for overheating – high temperature can permanently damage this product. With every degree above norm, the magnet's capacity momentarily drops. Refrain from using this product close to heaters higher than its safe range. Exceeding the critical threshold will lead to permanent loss of magnetism.

*Technical advisory: Thermal stability depends not only on the material grade, as well as the dimension ratios. Low-profile magnets (low Pc) risk losing magnetic properties sooner than taller cylinders. Warning indicator in the table signals a risk of irreversible loss for this specific geometry.

Two magnetic products attract each other from a significantly greater distance than a magnet and sheet setup. The setup of magnet-to-magnet creates a more powerful interaction and a wider radius of performance. Planning to create a solid fastener? Apply two magnets instead of a neodymium and a steel. Be careful that when bringing together two magnets, the collision energy is massive. The levitation is slightly lower than the connection force, but still large.
*Flux density for N-N configuration is approximately ~0 Gs at the midpoint of the gap (caused by magnetic field nullification).
* Figures demonstrate shear force of two identical magnets (friction ~0.15 for Ni-Ni plating).

Powerful magnet radiation poses a real danger to electronic devices and pacemakers. These NdFeB products produce a flux that disrupts operation of digital equipment. Be aware: the invisible magnetic field passes through tissues and housings. Special caution must be taken by people with hearing aids and insulin pumps. Also at risk are: automatic timepieces, car keys, speakers, and screens. Do not place the magnet near cards, hard drives, or precise measuring instruments.

Magnetic elements are delicate – a violent impact against metal can result in shattering. Pay attention to connection velocity – a neodymium left loose becomes dangerous. Kinetic force can destroy the magnet or painful pinches to skin. Be sure to control the product during mounting so it doesn't hit with great force against the steel surface. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Use safety goggles when working with large magnets.

*Note: On a vertical surface, the magnet holds only a fraction of its max power.

2. Efficiency vs thickness

*Thin steel (e.g. computer case) severely reduces the holding force.

3. Power loss vs temp

*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) = 1.59

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.

This product is a very strong rod magnet, made from advanced NdFeB material, which, with dimensions of Ø5x30 mm, guarantees optimal power. The MW 5x30 / N38 model is characterized by high dimensional repeatability and industrial build quality, making it a perfect solution for professional engineers and designers. As a magnetic rod with significant force (approx. 0.45 kg), this product is available off-the-shelf from our European logistics center, ensuring lightning-fast order fulfillment. Furthermore, 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 DIY projects, advanced automation, and broadly understood industry, serving as a positioning or actuating element. Thanks to the pull force of 4.40 N with a weight of only 4.42 g, this rod is indispensable in miniature devices and wherever every gram matters.

Since our magnets have a very precise dimensions, the best method is to glue them into holes with a slightly larger diameter (e.g., 5.1 mm) using two-component epoxy glues. To ensure stability in automation, specialized industrial adhesives 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 the strongest magnets in the same volume (Ø5x30), 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 Ø5x30 mm, which, at a weight of 4.42 g, makes it an element with high magnetic energy density. The key parameter here is the lifting capacity amounting to approximately 0.45 kg (force ~4.40 N), which, with such compact dimensions, proves the high power of the NdFeB material. 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 5 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.

Pros as well as cons of neodymium magnets.

Pros

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

They do not lose magnetism, even during approximately 10 years – the reduction in strength is only ~1% (theoretically),
They have excellent resistance to magnetism drop due to external fields,
The use of an aesthetic finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
Magnetic induction on the top side of the magnet remains very high,
Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
Possibility of precise modeling and modifying to atypical applications,
Versatile presence in electronics industry – they are utilized in computer drives, brushless drives, medical equipment, also other advanced devices.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which allows their use in small systems

Cons

Disadvantages of neodymium magnets:

Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a strong case, which not only protects them against impacts but also raises their durability
Neodymium magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape and 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 suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
We suggest casing - magnetic mechanism, due to difficulties in producing threads inside the magnet and complicated shapes.
Possible danger to health – tiny shards of magnets can be dangerous, in case of ingestion, which gains importance in the context of child health protection. Furthermore, small elements of these devices can be problematic in diagnostics medical after entering the body.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities

Lifting parameters

Best holding force of the magnet in ideal parameters – what contributes to it?

Information about lifting capacity was determined for ideal contact conditions, taking into account:

using a base made of high-permeability steel, functioning as a circuit closing element
possessing a massiveness of minimum 10 mm to ensure full flux closure
with a surface perfectly flat
without the slightest air gap between the magnet and steel
under perpendicular force vector (90-degree angle)
at temperature room level

Determinants of practical lifting force of a magnet

Please note that the magnet holding will differ subject to the following factors, in order of importance:

Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
Angle of force application – highest force is reached only during perpendicular pulling. The force required to slide of the magnet along the plate is usually several times lower (approx. 1/5 of the lifting capacity).
Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
Material composition – different alloys attracts identically. High carbon content worsen the interaction with the magnet.
Base smoothness – the smoother and more polished the plate, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
Operating temperature – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).

Lifting capacity was assessed using a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, however under shearing force the lifting capacity is smaller. In addition, even a small distance between the magnet and the plate reduces the load capacity.

Safety rules for work with neodymium magnets

Keep away from electronics

A powerful magnetic field negatively affects the operation of compasses in phones and GPS navigation. Maintain magnets close to a smartphone to prevent damaging the sensors.

Allergic reactions

Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction occurs, immediately stop working with magnets and wear gloves.

Thermal limits

Do not overheat. Neodymium magnets are susceptible to temperature. If you require resistance above 80°C, inquire about HT versions (H, SH, UH).

Physical harm

Protect your hands. Two powerful magnets will join instantly with a force of several hundred kilograms, crushing everything in their path. Be careful!

Warning for heart patients

Patients with a heart stimulator should maintain an large gap from magnets. The magnetic field can stop the functioning of the implant.

Protect data

Avoid bringing magnets close to a purse, computer, or screen. The magnetism can permanently damage these devices and wipe information from cards.

Fire risk

Mechanical processing of NdFeB material carries a risk of fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.

Respect the power

Before starting, read the rules. Sudden snapping can destroy the magnet or injure your hand. Be predictive.

Risk of cracking

Neodymium magnets are sintered ceramics, meaning they are very brittle. Collision of two magnets will cause them shattering into small pieces.

This is not a toy

NdFeB magnets are not suitable for play. Accidental ingestion of multiple magnets can lead to them pinching intestinal walls, which constitutes a critical condition and requires urgent medical intervention.
