Pulling power weakens drastically with every mm of distance. Remember that even the smallest gap (e.g., contamination, varnish, rust) significantly weakens the grip. Neodymiums hold optimally during direct contact; gap drastically cuts the force. Observe how quickly the load capacity fall, when the magnet does not touch flatly to the metal substrate. When calculating the arrangement, discard additional spacers.

The table below defines the approximate holding capacity necessary to start the shifting of the magnet downwards against a vertical metal surface (considering standard friction). This value depends on the air gap between the magnet and the surface.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MW 14x2 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.44 kg / 0.98 LBS 444.0 g / 4.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.30 kg / 0.65 LBS 296.0 g / 2.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.15 kg / 0.33 LBS 148.0 g / 1.5 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.74 kg / 1.63 LBS 740.0 g / 7.3 N

When placing a element on a vertical wall (e.g., a fridge), it will only hold barely about 1/5 of its nominal power. Gravitational force and a weak degree of grip influence the fact that magnets slide down faster than they pop off the substrate. Want to create a hanger? Consider that the shear force is noticeably lower than the maximum static pull force. On a smooth steel, the magnet will slip down under a significantly smaller weight. Utilizing a rubberized layer can significantly improve the result.

A too thin steel is unable to conduct the entire magnetic field, which wastes potential of the holder. Should you attach a powerful product to a too thin substrate, the magnetism will pass right through and the attraction force will be weaker. To achieve the maximum of this magnet's power, you require a sufficiently solid element of steel. The material oversaturation causes that on thin elements (e.g., thin profiles), the magnet works worse. We advise picking the steel thickness from these parameters.

Classic neodymiums lose parameters above the temperature limit. Avoid high temperatures – heat can irreversibly demagnetize this product. With increasing heat, the neodymium's force temporarily decreases. Do not use this magnet close to ovens higher than its working range. Too high temperature will result in destruction of magnetic properties.

*Important note: Heat tolerance is determined by both grade, but also on the magnet's shape. Thin magnets (low Pc) may lose charge permanently at lower temperatures than taller cylinders. Red status in the table indicates permanent field degradation for this specific geometry.

Two magnets attract each other from a much further distance than a magnet and steel setup. The connection of magnet-to-magnet creates a more powerful interaction and a wider radius of action. Planning to create a solid fastener? Apply two magnets instead of one magnet and a striker plate. Be careful that when attracting two neodymiums, the pinch force is massive. The repulsion force is a bit weaker than the attraction, but still significant.
*Flux density in repulsion mode drops to ~0 Gs at the geometric center of the gap (due to field cancellation).
Attention: Figures show friction force of two matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni plating).

Extremely neodym field is a real danger to electronics as well as pacemakers. These magnets produce a field that destroys function of sensitive medical devices. Be aware: the invisible magnetic field penetrates the body and glass. Exceptional care must be taken by people with hearing aids and insulin pumps. Also at risk are: mechanical watches, car keys, speakers, and screens. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Neodymium magnets are prone to chipping – a collision with steel causes immediate chipping. Control the attraction moment – a magnet released freely turns into a projectile. Kinetic force can destroy the magnet or injury to skin. Hold the magnet firmly during installation so it doesn't slam with momentum against the metal. A contact at a velocity of dozens of km/h ends with a crack of the magnet. Wear eye protection when working with large magnets.

Rust risk: 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. However, remember the water resistance when pulling the rope quickly.

1. Vertical hold

*Note: On a vertical wall, the magnet holds merely ~20% of its nominal pull.

2. Steel thickness impact

*Thin metal sheet (e.g. 0.5mm PC case) drastically reduces 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) = 0.22

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, composed of modern NdFeB material, which, at dimensions of Ø14x2 mm, guarantees maximum efficiency. This specific item is characterized by a tolerance of ±0.1mm and professional build quality, making it an excellent solution for professional engineers and designers. As a magnetic rod with significant force (approx. 1.48 kg), this product is in stock from our warehouse in Poland, ensuring quick order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating shields 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 pull force of 14.50 N with a weight of only 2.31 g, this cylindrical magnet is indispensable in miniature devices and wherever low weight is crucial.

Due to the delicate structure of the ceramic sinter, you must not use force-fitting (so-called press-fit), as this risks immediate cracking of this professional component. To ensure stability in industry, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.

Grade N38 is the most popular standard for industrial neodymium magnets, offering an optimal price-to-power ratio and operational stability. If you need the strongest magnets in the same volume (Ø14x2), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.

This model is characterized by dimensions Ø14x2 mm, which, at a weight of 2.31 g, makes it an element with high magnetic energy density. The value of 14.50 N means that the magnet is capable of holding a weight many times exceeding its own mass of 2.31 g. The product has a [NiCuNi] coating, which protects the surface against external factors, giving it an aesthetic, silvery shine.

This rod magnet is magnetized axially (along the height of 2 mm), which means that the N and S poles are located on the flat, circular surfaces. 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 as well as weaknesses of neodymium magnets.

Pros

Besides their high retention, neodymium magnets are valued for these benefits:

They virtually do not lose strength, because even after ten years the decline in efficiency is only ~1% (according to literature),
They are extremely resistant to demagnetization induced by external disturbances,
A magnet with a smooth silver surface has an effective appearance,
The surface of neodymium magnets generates a powerful magnetic field – this is a key feature,
Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
Thanks to versatility in shaping and the ability to customize to individual projects,
Key role in electronics industry – they find application in HDD drives, brushless drives, precision medical tools, and industrial machines.
Thanks to their power density, small magnets offer high operating force, with minimal size,

Limitations

Drawbacks and weaknesses of neodymium magnets and proposals for their use:

They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
We suggest cover - magnetic mechanism, due to difficulties in creating threads inside the magnet and complex shapes.
Health risk related to microscopic parts of magnets are risky, when accidentally swallowed, which is particularly important in the context of child health protection. It is also worth noting that small components of these magnets are able to be problematic in diagnostics medical after entering the body.
Due to complex production process, their price is higher than average,

Holding force characteristics

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

Information about lifting capacity was defined for the most favorable conditions, including:

on a plate made of structural steel, effectively closing the magnetic flux
whose thickness reaches at least 10 mm
with an ground contact surface
under conditions of no distance (metal-to-metal)
under axial force direction (90-degree angle)
at temperature approx. 20 degrees Celsius

Practical aspects of lifting capacity – factors

In real-world applications, the actual holding force depends on a number of factors, ranked from most significant:

Distance – the presence of foreign body (rust, dirt, gap) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
Load vector – maximum parameter is obtained only during perpendicular pulling. The force required to slide of the magnet along the plate is typically many times smaller (approx. 1/5 of the lifting capacity).
Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
Chemical composition of the base – mild steel gives the best results. Alloy admixtures lower magnetic permeability and holding force.
Surface structure – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Roughness acts like micro-gaps.
Thermal factor – hot environment weakens pulling force. Too high temperature can permanently damage the magnet.

Lifting capacity was measured with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, however under shearing force the load capacity is reduced by as much as 5 times. Additionally, even a slight gap between the magnet and the plate decreases the holding force.

Safety rules for work with NdFeB magnets

Finger safety

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

Handling guide

Handle with care. Neodymium magnets act from a long distance and snap with huge force, often quicker than you can move away.

Do not give to children

Absolutely keep magnets away from children. Ingestion danger is high, and the effects of magnets connecting inside the body are life-threatening.

Electronic hazard

Powerful magnetic fields can erase data on credit cards, HDDs, and storage devices. Keep a distance of min. 10 cm.

Dust explosion hazard

Fire warning: Rare earth powder is explosive. Do not process magnets without safety gear as this risks ignition.

Nickel allergy

It is widely known that nickel (standard magnet coating) is a potent allergen. If your skin reacts to metals, prevent direct skin contact or choose encased magnets.

Medical implants

Warning for patients: Powerful magnets disrupt electronics. Maintain minimum 30 cm distance or request help to handle the magnets.

Power loss in heat

Do not overheat. NdFeB magnets are susceptible to temperature. If you need resistance above 80°C, ask us about special high-temperature series (H, SH, UH).

GPS Danger

GPS units and mobile phones are highly sensitive to magnetism. Direct contact with a powerful NdFeB magnet can ruin the sensors in your phone.

Magnet fragility

Watch out for shards. Magnets can fracture upon uncontrolled impact, ejecting shards into the air. Eye protection is mandatory.
