Grip strength decreases sharply with every subsequent millimeter of gap. Remember that even a very thin break (e.g., dirt, paint, rust) significantly reduces the pull force. Magnetic products hold strongest during direct contact; air break kills the power. Analyze how flashily the load capacity fall, when the magnet does not adhere flatly to the steel surface. When planning the arrangement, discard unnecessary gaps.

This section calculates the theoretical shear load needed to initiate the downward movement of the magnet down against a upright metal surface (considering typical friction). This parameter depends on the 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 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 placing a element on a upright surface (e.g., a car body), it will only hold only about 1/5 of its nominal power. Gravitational force as well as a weak degree of grip influence the fact that products move down faster than they detach. Want to create a wall mount? Remember that the sliding force is significantly lower than the perpendicular breakaway force. On a painted metal, the element will slip down under a much lighter 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 full magnetic flux, which wastes potential of the magnet. Should you mount a strong magnet to a weak sheet, the magnetism will penetrate right through and the pull force will drop sharply. To squeeze full efficiency of this magnet's potential, you require a sufficiently solid element of metal. The saturation phenomenon causes that on sheet metal structures (e.g., car bodies), the holder holds weaker. We advise picking the steel dimension based on the following data.

Classic neodymiums change their properties parameters after exceeding the maximum temperature. Avoid high temperatures – high temperature can permanently demagnetize this magnet. With every degree above norm, the magnet's power briefly drops. Avoid using this product close to heaters higher than its operating temperature limit. Exceeding the critical threshold will cause irreversible degradation of magnetic properties.

*Important note: Temperature resistance is determined by both grade, and the Permeance Coefficient Pc. Thin magnets (low Pc) may lose charge permanently sooner than taller cylinders. Warning indicator in the table indicates permanent field degradation for this particular item.

Two magnets attract each other from a wider radius than a magnet and steel setup. The setup of two magnets produces a massive flux and a further horizon of operation. Planning to create a powerful holder? Apply two magnets instead of a neodymium and a striker plate. Be careful that when attracting two neodymiums, the impact force is massive. The levitation is a bit weaker than the connection force, but still significant.
*The magnetic induction in repulsion mode reaches ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
* Estimates apply to friction force of dual same neodymium magnets (friction ~0.15 for Ni-Ni coating).

Powerful magnet radiation is a real danger to electronics as well as pacemakers. These NdFeB products generate a flux that prevents correct functioning of sensitive medical devices. Notice: the invisible magnetic field penetrates the body and housings. Increased vigilance must be exercised by people with cochlear implants and drug dispensers. Influence will be felt by: automatic timepieces, car keys, membranes, and screens. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

Table 8: Impact energy (kinetic energy) - warning

100 mm	32.18 km/h (8.94 m/s)	0.18 J

Magnetic elements are very brittle – a violent impact against metal can result in shattering. Watch the impact speed – a magnet released freely becomes dangerous. Impact energy can trigger coating fragments or injury to fingers. Always hold the magnet during bringing near metal so it doesn't slam with momentum against the metal. A collision at high speed ends with a crack of the neodymium. Wear eye protection when playing with powerful specimens.

Warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

Contrary to myths, water does not block the magnetic field. Buoyancy helps in lifting finds.

1. Shear force

*Warning: On a vertical wall, the magnet holds only ~20% of its perpendicular strength.

2. Steel saturation

*Thin metal sheet (e.g. computer case) severely weakens the holding force.

3. Power loss vs temp

*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) = 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.

The offered product is a very strong cylinder magnet, made from modern NdFeB material, which, at dimensions of Ø5x30 mm, guarantees optimal power. This specific item is characterized by high dimensional repeatability and professional build quality, making it an excellent solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 0.45 kg), this product is in stock from our European logistics center, ensuring lightning-fast order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating effectively protects it against corrosion in typical 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 cylindrical magnet is indispensable in miniature devices and wherever low weight is crucial.

Due to the brittleness of the NdFeB material, you must not use force-fitting (so-called press-fit), as this risks chipping the coating of this professional component. To ensure long-term durability 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 professional neodymium magnets, offering an optimal price-to-power ratio and operational stability. 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 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 defined dimensions, proves the high power of the NdFeB material. The product has a [NiCuNi] coating, which protects the surface against oxidation, giving it an aesthetic, silvery shine.

This cylinder is magnetized axially (along the height of 30 mm), which means that the N and S poles are located on the flat, circular surfaces. 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 rare earth magnets.

Advantages

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

They have constant strength, and over nearly 10 years their performance decreases symbolically – ~1% (according to theory),
Magnets very well resist against loss of magnetization caused by foreign field sources,
In other words, due to the glossy finish of gold, the element looks attractive,
The surface of neodymium magnets generates a maximum magnetic field – this is one of their assets,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
Possibility of accurate creating as well as adjusting to concrete requirements,
Fundamental importance in innovative solutions – they serve a role in mass storage devices, motor assemblies, precision medical tools, also modern systems.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which makes them useful in compact constructions

Weaknesses

Disadvantages of NdFeB magnets:

Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a special holder, which not only protects them against impacts but also increases their durability
Neodymium magnets decrease their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
Limited ability of creating nuts in the magnet and complex shapes - recommended is a housing - mounting mechanism.
Potential hazard to health – tiny shards of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child safety. Additionally, small components of these products are able to disrupt the diagnostic process medical after entering the body.
Due to complex production process, their price is higher than average,

Lifting parameters

Optimal lifting capacity of a neodymium magnet – what it depends on?

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

on a plate made of structural steel, effectively closing the magnetic field
whose thickness is min. 10 mm
with a plane free of scratches
with zero gap (without paint)
during detachment in a direction perpendicular to the mounting surface
at conditions approx. 20°C

Practical lifting capacity: influencing factors

Effective lifting capacity is affected by working environment parameters, including (from most important):

Distance (betwixt the magnet and the plate), because even a very small distance (e.g. 0.5 mm) can cause a drastic drop in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
Plate thickness – insufficiently thick steel does not close the flux, causing part of the power to be escaped into the air.
Metal type – not every steel reacts the same. Alloy additives worsen the attraction effect.
Surface condition – ground elements guarantee perfect abutment, which improves field saturation. Uneven metal reduce efficiency.
Thermal factor – hot environment reduces magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.

Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, however under attempts to slide the magnet the lifting capacity is smaller. In addition, even a small distance between the magnet and the plate reduces the holding force.

Warnings

Combustion hazard

Machining of NdFeB material poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.

Material brittleness

NdFeB magnets are ceramic materials, meaning they are fragile like glass. Clashing of two magnets will cause them shattering into small pieces.

Allergy Warning

Medical facts indicate that the nickel plating (standard magnet coating) is a common allergen. If your skin reacts to metals, refrain from direct skin contact or choose versions in plastic housing.

Impact on smartphones

A powerful magnetic field interferes with the operation of magnetometers in phones and navigation systems. Keep magnets near a device to prevent breaking the sensors.

Implant safety

Medical warning: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.

Bodily injuries

Large magnets can crush fingers instantly. Do not put your hand betwixt two strong magnets.

Maximum temperature

Standard neodymium magnets (N-type) lose magnetization when the temperature exceeds 80°C. Damage is permanent.

Immense force

Use magnets with awareness. Their powerful strength can shock even professionals. Stay alert and respect their force.

This is not a toy

Always keep magnets out of reach of children. Risk of swallowing is significant, and the effects of magnets connecting inside the body are very dangerous.

Cards and drives

Do not bring magnets near a wallet, laptop, or TV. The magnetism can destroy these devices and erase data from cards.

Caution! More info about risks in the article: Safety of working with magnets.
