Pulling power weakens significantly with every mm of gap. Remember that every additional insulation layer (e.g., dirt, varnish, veneer) significantly reduces the pull force. Neodymiums hold optimally at the point of direct contact; air break weakens the power. Observe how quickly the parameters plummet, when the magnet does not touch tightly to the metal substrate. When calculating the mounting, avoid additional spacers.

This section shows the estimated weight limit needed to initiate the downward movement of the magnet downwards on a vertical steel wall (assuming typical friction). This value is a function of the separation distance between the magnet and the surface.

Table 3: Vertical assembly (shearing) - vertical pull
MW 18.9x10 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	3.50 kg / 7.72 lbs 3504.0 g / 34.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	2.34 kg / 5.15 lbs 2336.0 g / 22.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	1.17 kg / 2.57 lbs 1168.0 g / 11.5 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	5.84 kg / 12.87 lbs 5840.0 g / 57.3 N

When hanging a magnet on a vertical surface (e.g., a car body), it will only hold just approx. 20%-30% of its nominal power. Gravity as well as a low friction coefficient cause that magnets slide down easier than they pull off. Planning a wall mount? Note that the shear force is much weaker than the maximum static pull force. On a slippery surface, the holder will slip down under a much lighter weight. Application of an anti-slip coating can significantly raise the stability.

A thin sheet is unable to absorb the entire magnetic field, which squanders power of the holder. Should you attach a powerful product to a weak sheet, the flux will pass right through and the pull force will drop sharply. To achieve the maximum of this neodymium's potential, you need a suitably thick piece of metal. The saturation phenomenon causes that on sheet metal structures (e.g., car bodies), the product holds weaker. We advise picking the steel cross-section according to the table below.

Classic neodymiums lose power above the temperature limit. Watch out for overheating – heat can permanently damage this magnet. As the temperature rises, the magnet's force briefly decreases. Do not use this magnet near heat sources exceeding its safe range. Exceeding the critical threshold will result in irreversible degradation of magnetism.

*Engineering note: Heat tolerance is determined by both grade, as well as the dimension ratios. Flat magnets (pancake types) may lose charge permanently under lower heat stress than taller cylinders. The danger warning in the table points to permanent field degradation for this particular item.

Two magnetic products interact from a wider radius than a magnet and steel combination. The setup of magnet-to-magnet creates a more powerful interaction and a larger range of performance. Planning to create a strong closure? Use a pair of magnets instead of one magnet and a steel. Exercise caution that when bringing together two magnets, the pinch force is massive. The levitation is slightly lower than the connection force, but still significant.
*Flux density between like poles reaches ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
Note: Results refer to shear force of two matching magnets (friction coefficient ~0.15 for Ni-Ni coating).

Powerful magnet radiation poses a real danger to IT equipment and medical implants. These NdFeB products generate a flux that disrupts operation of digital equipment. Notice: the unseen radiation acts through matter and glass. Special caution must be taken by people with cochlear implants and drug dispensers. The risk also applies to: automatic timepieces, car keys, membranes, and displays. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Neodymium magnets are very brittle – a collision with steel can result in shattering. Watch the impact speed – a magnet released freely becomes dangerous. Striking energy can destroy the magnet or injury to fingers. Hold the magnet firmly during mounting so it doesn't hit with great force against the steel surface. A contact at a velocity of dozens of km/h ends with a crack of the magnet. Wear safety glasses when working with large magnets.

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

The magnetic field penetrates through water without any losses. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Wall mount (shear)

*Caution: On a vertical wall, the magnet retains just ~20% of its max power.

2. Plate thickness effect

*Thin metal sheet (e.g. 0.5mm PC case) drastically limits the holding force.

3. Thermal stability

*For N38 material, the safety limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.61

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 a very strong rod magnet, composed of durable NdFeB material, which, with dimensions of Ø18.9x10 mm, guarantees the highest energy density. This specific item is characterized by a tolerance of ±0.1mm and industrial build quality, making it an excellent solution for professional engineers and designers. As a cylindrical magnet with significant force (approx. 11.68 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring lightning-fast order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

This model is created for building electric motors, advanced Hall effect sensors, and efficient filters, where field concentration on a small surface counts. Thanks to the pull force of 114.54 N with a weight of only 21.04 g, this cylindrical magnet is indispensable in electronics and wherever low weight is crucial.

Since our magnets have a very precise dimensions, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 18.9.1 mm) using 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 operational stability. If you need even stronger magnets in the same volume (Ø18.9x10), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.

The presented product is a neodymium magnet with precisely defined parameters: diameter 18.9 mm and height 10 mm. The value of 114.54 N means that the magnet is capable of holding a weight many times exceeding its own mass of 21.04 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 18.9 mm. Such an arrangement is most desirable 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 diametrically if your project requires it.

Strengths and weaknesses of neodymium magnets.

Benefits

In addition to their pulling strength, neodymium magnets provide the following advantages:

They have unchanged lifting capacity, and over around 10 years their performance decreases symbolically – ~1% (in testing),
They are extremely resistant to demagnetization induced by external field influence,
By using a decorative coating of gold, the element has an professional look,
The surface of neodymium magnets generates a unique magnetic field – this is one of their assets,
Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
Thanks to the ability of flexible shaping and adaptation to specialized projects, magnetic components can be modeled in a broad palette of forms and dimensions, which makes them more universal,
Universal use in modern industrial fields – they are commonly used in magnetic memories, electromotive mechanisms, diagnostic systems, and complex engineering applications.
Thanks to their power density, small magnets offer high operating force, in miniature format,

Disadvantages

What to avoid - cons of neodymium magnets and proposals for their use:

They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
Neodymium magnets lose their force 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 stability even at temperatures up to 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, in case of application outdoors
Limited possibility of making threads in the magnet and complicated forms - recommended is a housing - magnet mounting.
Health risk related to microscopic parts of magnets pose a threat, in case of ingestion, which becomes key in the context of child safety. Additionally, small components of these magnets can complicate diagnosis medical in case of swallowing.
Due to expensive raw materials, their price exceeds standard values,

Pull force analysis

Maximum lifting capacity of the magnet – what it depends on?

Magnet power was determined for optimal configuration, including:

with the use of a sheet made of special test steel, guaranteeing full magnetic saturation
with a cross-section no less than 10 mm
with a plane free of scratches
under conditions of ideal adhesion (metal-to-metal)
under axial force vector (90-degree angle)
at ambient temperature room level

Lifting capacity in practice – influencing factors

Please note that the working load may be lower influenced by the following factors, starting with the most relevant:

Gap (betwixt the magnet and the plate), as even a microscopic distance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to paint, corrosion or dirt).
Force direction – catalog parameter refers to detachment vertically. When attempting to slide, the magnet exhibits much less (typically approx. 20-30% of maximum force).
Base massiveness – insufficiently thick plate causes magnetic saturation, causing part of the power to be lost to the other side.
Material composition – not every steel attracts identically. High carbon content worsen the attraction effect.
Surface finish – ideal contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
Heat – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).

Lifting capacity was determined by applying a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, however under shearing force the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate decreases the load capacity.

H&S for magnets

Conscious usage

Exercise caution. Rare earth magnets act from a distance and connect with huge force, often faster than you can move away.

Bodily injuries

Pinching hazard: The attraction force is so great that it can cause hematomas, crushing, and broken bones. Protective gloves are recommended.

Danger to the youngest

Always keep magnets away from children. Ingestion danger is high, and the consequences of magnets clamping inside the body are fatal.

Fragile material

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

Electronic hazard

Do not bring magnets near a purse, computer, or screen. The magnetism can irreversibly ruin these devices and wipe information from cards.

Thermal limits

Avoid heat. Neodymium magnets are susceptible to temperature. If you need resistance above 80°C, ask us about HT versions (H, SH, UH).

Warning for allergy sufferers

Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If redness appears, immediately stop handling magnets and use protective gear.

Threat to navigation

Remember: neodymium magnets generate a field that disrupts precision electronics. Keep a separation from your phone, device, and navigation systems.

Medical implants

Medical warning: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.

Dust is flammable

Drilling and cutting of NdFeB material carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.

Danger! More info about hazards in the article: Magnet Safety Guide.
