Pulling power drops sharply with every subsequent millimeter of distance. Remember that every additional insulation layer (e.g., dirt, paint, rust) strongly reduces the pull force. Magnets work most effectively in perfect adhesion; distance drastically cuts the power. Observe how flashily the load capacity plummet, when the magnet does not adhere flatly to the metal substrate. When calculating the mounting, eliminate redundant distances.

This section indicates the approximate force needed to start the shifting of the magnet downwards along a vertical metal surface (considering typical friction coefficient). This parameter varies with the gap size between the magnet and the surface.

Table 3: Wall mounting (sliding) - vertical pull

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	8.32 kg / 18.34 LBS 8319.0 g / 81.6 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	5.55 kg / 12.23 LBS 5546.0 g / 54.4 N

Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	13.87 kg / 30.57 LBS 13865.0 g / 136.0 N

When hanging a magnet on a upright wall (e.g., a car body), it will maintain only about 1/5 of its maximum pull force. Gravity and a low friction coefficient cause that magnets slip faster than they detach. Planning a hanger? Remember that the sliding force is noticeably lower than the perpendicular breakaway force. On a slippery surface, the holder will slide down under a significantly smaller load. Application of an anti-slip layer can effectively increase the grip.

A too thin steel cannot focus the entire magnetic field, which squanders power of the magnet. If you attach a powerful product to a weak sheet, the magnetism will penetrate right through and the attraction force will be weaker. To achieve full efficiency of this neodymium's potential, you need a suitably thick backing of metal. The saturation phenomenon means that on delicate walls (e.g., car bodies), the magnet holds weaker. We advise picking the steel thickness according to the table below.

Standard neodymium magnets irreversibly lose strength above the temperature limit. Avoid high temperatures – high temperature can irreversibly demagnetize this magnet. With increasing heat, the neodymium's force temporarily decreases. Avoid using this product close to heaters exceeding its safe range. Too high temperature will lead to irreversible degradation of magnetic properties.

*Important note: Thermal stability is determined by both grade, as well as the dimension ratios. Flat magnets (low Pc) risk losing magnetic properties under lower heat stress compared to rod magnets. The danger warning in the table points to permanent field degradation for this specific geometry.

Two magnets attract each other from a wider radius than a neodymium and metal setup. Such a system of two magnets generates a stronger field and a further horizon of operation. Designing a strong closure? Apply two magnets instead of one magnet and a steel. Exercise caution that when attracting two neodymiums, the pinch force is extreme. The repulsion force is a bit weaker than the attraction, but still significant.
*The magnetic induction in repulsion mode reaches ~0 Gs in the exact middle between the magnets (resulting from vector opposition).
Important: Estimates demonstrate sliding force of a pair of matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

Extremely neodym field poses a serious hazard to electronics and medical implants. These NdFeB products produce a field that destroys function of sensitive medical devices. Be aware: the unseen radiation penetrates the body and housings. Special caution must be exercised by people with cochlear implants and drug dispensers. Influence will be felt by: mechanical watches, remotes, speakers, and screens. Do not bring the product near payment cards, hard drives, or sensitive navigation tools.

Neodymium magnets are prone to chipping – a violent impact against metal can result in shattering. Pay attention to connection velocity – a neodymium left loose becomes dangerous. Striking energy can destroy the magnet or painful pinches to fingers. Always hold the magnet during bringing near metal so it doesn't slam with momentum against the metal. A contact at a velocity of dozens of km/h means shattering of the neodymium. Wear safety glasses when playing with powerful specimens.

Rust risk: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

In water, the magnet feels stronger thanks to Archimedes' principle. However, remember the water resistance when pulling the rope quickly.

1. Shear force

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

2. Steel thickness impact

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

3. Temperature resistance

*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) = 0.35

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 modern NdFeB material, which, at dimensions of Ø40x10 mm, guarantees maximum efficiency. This specific item is characterized by high dimensional repeatability and professional build quality, making it a perfect solution for the most demanding engineers and designers. As a magnetic rod with impressive force (approx. 27.73 kg), this product is in stock from our European logistics center, ensuring rapid order fulfillment. Additionally, its Ni-Cu-Ni coating effectively protects it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is perfect for building electric motors, advanced sensors, and efficient filters, where field concentration on a small surface counts. Thanks to the high power of 271.99 N with a weight of only 94.25 g, this rod 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, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.

Grade N38 is the most popular standard for professional neodymium magnets, offering an optimal price-to-power ratio and high resistance to demagnetization. If you need even stronger magnets in the same volume (Ø40x10), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.

The presented product is a neodymium magnet with precisely defined parameters: diameter 40 mm and height 10 mm. The value of 271.99 N means that the magnet is capable of holding a weight many times exceeding its own mass of 94.25 g. The product has a [NiCuNi] coating, which protects the surface 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 40 mm. 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 Nd₂Fe₁₄B magnets.

Strengths

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

Their power remains stable, and after approximately 10 years it drops only by ~1% (according to research),
They feature excellent resistance to magnetism drop when exposed to external fields,
Thanks to the glossy finish, the layer of Ni-Cu-Ni, gold-plated, or silver-plated gives an elegant appearance,
Neodymium magnets achieve maximum magnetic induction on a contact point, which ensures high operational effectiveness,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
Possibility of exact machining as well as adjusting to atypical requirements,
Fundamental importance in electronics industry – they are used in mass storage devices, motor assemblies, advanced medical instruments, and modern systems.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Cons

Disadvantages of neodymium magnets:

They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
Due to limitations in creating threads and complicated forms in magnets, we recommend using casing - magnetic holder.
Health risk related to microscopic parts of magnets are risky, in case of ingestion, which gains importance in the context of child health protection. Additionally, tiny parts of these products are able to disrupt the diagnostic process medical in case of swallowing.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Holding force characteristics

Optimal lifting capacity of a neodymium magnet – what affects it?

The declared magnet strength refers to the peak performance, obtained under ideal test conditions, meaning:

with the contact of a sheet made of low-carbon steel, ensuring full magnetic saturation
whose thickness reaches at least 10 mm
characterized by even structure
without the slightest clearance between the magnet and steel
under vertical force direction (90-degree angle)
at conditions approx. 20°C

Lifting capacity in real conditions – factors

In practice, the real power is determined by many variables, presented from crucial:

Distance (between the magnet and the metal), as even a tiny clearance (e.g. 0.5 mm) can cause a drastic drop in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
Angle of force application – highest force 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).
Base massiveness – insufficiently thick steel causes magnetic saturation, causing part of the power to be escaped to the other side.
Metal type – different alloys attracts identically. High carbon content weaken the attraction effect.
Base smoothness – the more even the plate, the better the adhesion and stronger the hold. Unevenness creates an air distance.
Heat – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and in frost gain strength (up to a certain limit).

Lifting capacity was measured by applying a polished steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under shearing force the lifting capacity is smaller. In addition, even a small distance between the magnet and the plate lowers the load capacity.

H&S for magnets

Flammability

Powder produced during grinding of magnets is self-igniting. Do not drill into magnets unless you are an expert.

Keep away from children

Neodymium magnets are not intended for children. Accidental ingestion of several magnets may result in them pinching intestinal walls, which constitutes a critical condition and necessitates urgent medical intervention.

Impact on smartphones

An intense magnetic field interferes with the operation of magnetometers in phones and navigation systems. Keep magnets close to a smartphone to prevent breaking the sensors.

Respect the power

Handle magnets with awareness. Their immense force can shock even experienced users. Plan your moves and do not underestimate their power.

Magnets are brittle

Despite metallic appearance, the material is delicate and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.

Warning for allergy sufferers

Certain individuals experience a hypersensitivity to Ni, which is the typical protective layer for neodymium magnets. Frequent touching may cause a rash. We suggest wear safety gloves.

Bone fractures

Mind your fingers. Two powerful magnets will join immediately with a force of massive weight, destroying everything in their path. Exercise extreme caution!

Do not overheat magnets

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

Health Danger

Medical warning: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.

Safe distance
