Grip strength decreases significantly with every subsequent millimeter of spacing. Note that even a very thin break (e.g., contamination, varnish, veneer) strongly weakens the grip. Magnets hold optimally in perfect adhesion; air break kills the power. Notice how rapidly the load capacity fall, when the magnet does not touch tightly to the metal substrate. When planning the mounting, avoid redundant distances.

The following data shows the approximate weight limit required to cause the sliding of the magnet downwards against a upright metal surface (assuming standard friction coefficient). This value varies with the air gap between the magnet and the surface.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces
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 LBS 135.0 g / 1.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.09 kg / 0.20 LBS 90.0 g / 0.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.05 kg / 0.10 LBS 45.0 g / 0.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.23 kg / 0.50 LBS 225.0 g / 2.2 N

When mounting a element on a vertical wall (e.g., a car body), it you can count on just about 1/5 of nominal attraction strength. Gravity and a low friction coefficient mean that holders slip easier than they detach. Designing a wall mount? Note that the shear force is significantly lower than the perpendicular breakaway force. On a smooth steel, the holder will slip down under a significantly smaller weight. Utilizing a rubberized layer can drastically increase the grip.

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

A too thin steel is incapable of take in the entire magnetic field, which weakens actual performance of the holder. If you attach a powerful product to a too thin substrate, the field will pass right through and the pull force will drop sharply. To utilize the maximum of this magnet's power, you need a suitably thick element of steel. The saturation effect means that on delicate walls (e.g., appliance housings), the holder shows lower pull force. We suggest choosing the steel cross-section based on the following data.

Standard neodymium magnets change their properties power above the temperature limit. Protect against heat – heat can permanently demagnetize this magnet. As the temperature rises, the magnet's capacity temporarily drops. Avoid using this magnet close to ovens higher than its safe range. Too high temperature will result in destruction of magnetic properties.

*Technical advisory: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Thin magnets (low permeance coefficient) may lose charge permanently at lower temperatures than taller cylinders. Warning indicator in the table indicates a risk of irreversible loss for this specific geometry.

Two strong neodymiums attract each other from a much further distance than a magnet and steel combination. The setup of magnet-to-magnet generates a stronger field and a further horizon of operation. Want to build a solid fastener? Use a pair of magnets instead of one magnet and a striker plate. Exercise caution that when bringing together two magnets, the collision energy is massive. The repulsion force is marginally weaker than the attraction, but still significant.
*The magnetic induction in repulsion mode reaches ~0 Gs at the midpoint of the gap (due to field cancellation).
Note: Figures demonstrate sliding force of a pair of matching magnets (friction coefficient ~0.15 for Ni-Ni coating).

Extremely neodym field poses a large risk to electronics as well as pacemakers. These NdFeB products generate a flux that prevents correct functioning of digital equipment. Remember: the invisible magnetic field penetrates the body and glass. Exceptional care must be exercised by people with cochlear implants and drug dispensers. Also at risk are: mechanical watches, car keys, speakers, and screens. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

Table 8: Collisions (cracking risk) - warning

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	10.18 km/h (2.83 m/s)	0.02 J

50 mm	22.75 km/h (6.32 m/s)	0.09 J
100 mm	32.18 km/h (8.94 m/s)	0.18 J

Magnetic elements are very brittle – a collision with steel risks their cracking. Pay attention to connection velocity – a neodymium left loose speeds with massive force. Kinetic force can trigger coating fragments or injury to skin. Always hold the magnet during bringing near metal so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Wear eye protection when working with powerful specimens.

Warning: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

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 surface, the magnet holds merely approx. 20-30% of its max power.

2. Efficiency vs thickness

*Thin steel (e.g. computer 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) = 1.59

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 offered product is a very strong cylindrical magnet, made from advanced NdFeB material, which, at dimensions of Ø5x30 mm, guarantees the highest energy density. This specific item features an accuracy of ±0.1mm and professional build quality, making it an ideal solution for the most demanding engineers and designers. As a cylindrical magnet with significant force (approx. 0.45 kg), this product is available off-the-shelf from our European logistics center, ensuring rapid order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

It finds application in modeling, advanced robotics, and broadly understood industry, serving as a fastening 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 electronics and wherever every gram matters.

Since our magnets have a tolerance of ±0.1mm, 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 long-term durability 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 modeling and machine building, where excessive miniaturization with maximum force is not required. 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 available off-the-shelf in our warehouse.

This model is characterized by dimensions Ø5x30 mm, which, at a weight of 4.42 g, makes it an element with impressive magnetic energy density. The value of 4.40 N means that the magnet is capable of holding a weight many times exceeding its own mass of 4.42 g. The product has a [NiCuNi] coating, which protects the surface against oxidation, giving it an aesthetic, silvery shine.

This rod magnet is magnetized axially (along the height of 30 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.

Advantages as well as disadvantages of rare earth magnets.

Strengths

Apart from their notable holding force, neodymium magnets have these key benefits:

They do not lose magnetism, even after approximately ten years – the drop in strength is only ~1% (theoretically),
They are noted for resistance to demagnetization induced by external magnetic fields,
The use of an metallic finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
Neodymium magnets generate maximum magnetic induction on a their surface, which allows for strong attraction,
Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures approaching 230°C and above...
Possibility of accurate machining and optimizing to defined needs,
Universal use in modern technologies – they serve a role in HDD drives, electric drive systems, medical devices, as well as technologically advanced constructions.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which allows their use in miniature devices

Weaknesses

What to avoid - cons of neodymium magnets: application proposals

At very strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their strength 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 recommend using waterproof magnets e.g. in rubber, plastic
Due to limitations in producing threads and complicated shapes in magnets, we recommend using cover - magnetic holder.
Possible danger resulting from small fragments of magnets are risky, in case of ingestion, which gains importance in the context of child health protection. Furthermore, small components of these products are able to disrupt the diagnostic process medical after entering the body.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Lifting parameters

Maximum holding power of the magnet – what affects it?

The specified lifting capacity represents the maximum value, measured under optimal environment, meaning:

with the contact of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
whose thickness reaches at least 10 mm
with a surface free of scratches
with total lack of distance (no impurities)
for force acting at a right angle (in the magnet axis)
at room temperature

Magnet lifting force in use – key factors

During everyday use, the actual holding force results from several key aspects, listed from crucial:

Space between surfaces – every millimeter of separation (caused e.g. by veneer or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
Force direction – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
Substrate thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
Steel grade – ideal substrate is pure iron steel. Hardened steels may have worse magnetic properties.
Plate texture – ground elements ensure maximum contact, which improves force. Rough surfaces weaken the grip.
Thermal factor – high temperature reduces pulling force. Too high temperature can permanently damage the magnet.

Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under shearing force the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate decreases the holding force.

H&S for magnets

Fragile material

Watch out for shards. Magnets can explode upon uncontrolled impact, launching shards into the air. Wear goggles.

Data carriers

Avoid bringing magnets near a wallet, laptop, or TV. The magnetic field can destroy these devices and erase data from cards.

Do not underestimate power

Be careful. Neodymium magnets attract from a distance and connect with huge force, often faster than you can move away.

Permanent damage

Monitor thermal conditions. Heating the magnet to high heat will destroy its magnetic structure and strength.

Metal Allergy

Some people have a sensitization to nickel, which is the typical protective layer for NdFeB magnets. Extended handling may cause skin redness. We strongly advise use protective gloves.

Implant safety

People with a pacemaker should keep an safe separation from magnets. The magnetic field can disrupt the functioning of the life-saving device.

Crushing force

Danger of trauma: The pulling power is so immense that it can cause hematomas, pinching, and even bone fractures. Protective gloves are recommended.

Compass and GPS

Remember: rare earth magnets produce a field that confuses precision electronics. Maintain a safe distance from your phone, device, and navigation systems.

Fire risk

Combustion risk: Neodymium dust is highly flammable. Do not process magnets without safety gear as this may cause fire.

Swallowing risk

NdFeB magnets are not toys. Eating multiple magnets may result in them connecting inside the digestive tract, which poses a severe health hazard and necessitates urgent medical intervention.
