Magnetic force decreases drastically with every subsequent millimeter of gap. Remember that even the smallest gap (e.g., dirt, paint, rust) noticeably diminishes the holding power. Neodymiums work strongest in perfect adhesion; air break kills the force. Notice how quickly the pull force drop, when the product does not adhere tightly to the metal substrate. When planning the mounting, eliminate additional spacers.

The following data shows the theoretical weight limit required to cause the downward movement of the magnet vertically against a upright metal surface (considering typical friction). This parameter varies with the separation distance between the magnet and the metal.

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

When hanging a holder on a vertical surface (e.g., a board), it will only hold barely approx. 1/5 of nominal attraction strength. Gravity as well as a low friction coefficient mean that holders move down easier than they detach. Designing a wall mount? Remember that the sliding force is noticeably lower than the perpendicular breakaway force. On a painted metal, the element will slide down under a much lighter cargo. Application of an anti-slip layer can drastically raise the stability.

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

A too thin steel is unable to focus the entire magnetic field, which weakens actual performance of the magnet. If you attach a powerful product to a weak sheet, the flux will penetrate right through and the holding will be smaller. To squeeze the maximum of this neodymium's power, you need a suitably thick element of metal. The material oversaturation causes that on sheet metal structures (e.g., car bodies), the holder shows lower pull force. We recommend selecting the steel dimension according to the table below.

Table 5: Thermal resistance (material behavior) - power drop
MW 5x30 / N38

100 °C	-28.8%	0.32 kg / 0.71 pounds 320.4 g / 3.1 N

Ordinary NdFeB products lose parameters above the temperature limit. Watch out for overheating – high temperature can permanently destroy this magnet. With increasing heat, the magnet's force briefly decreases. Do not use this product close to ovens exceeding its working range. Too high temperature will lead to permanent loss of magnetic properties.

*Technical advisory: Temperature resistance is determined by both grade, as well as the dimension ratios. Flat magnets (low Pc) are more susceptible to demagnetization sooner than long magnets. The danger warning in the table points to permanent field degradation for this specific geometry.

Two magnetic products interact from a significantly greater distance than a neodymium and metal combination. Such a system of magnet-to-magnet produces a massive flux and a further horizon of operation. Want to build a strong closure? Apply two magnets instead of a neodymium and a steel. Remember that when attracting two neodymiums, the collision energy is huge. The repulsion force is slightly lower than the connection force, but still impressive.
*The magnetic induction between like poles reaches ~0 Gs in the exact middle between the magnets (resulting from vector opposition).
Important: Estimates demonstrate friction force of two matching magnets (friction ~0.15 for Ni-Ni coating).

Extremely neodym field poses a real danger to electronics and medical implants. These NdFeB products produce a field that disrupts operation of digital equipment. Remember: the invisible magnetic field acts through matter and glass. Exceptional care must be taken by people with hearing aids and drug dispensers. Influence will be felt by: mechanical watches, car keys, speakers, and screens. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

Magnetic elements are very brittle – a strong collision with metal can result in shattering. Pay attention to connection velocity – a neodymium left loose speeds with massive force. Striking energy can destroy the magnet or injury to fingers. Be sure to control the product during installation so it doesn't slam with momentum against the steel surface. A collision at high speed ends with a crack of the neodymium. Use safety goggles 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. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Sliding resistance

*Caution: On a vertical surface, the magnet holds only a fraction of its perpendicular strength.

2. Efficiency vs thickness

*Thin steel (e.g. computer case) severely reduces 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, composed of 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 excellent solution for the most demanding engineers and designers. As a magnetic rod with significant force (approx. 0.45 kg), this product is available off-the-shelf from our European logistics center, ensuring rapid order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

This model is perfect for building electric motors, advanced sensors, and efficient magnetic separators, where maximum induction on a small surface counts. Thanks to the pull force of 4.40 N with a weight of only 4.42 g, this rod is indispensable in miniature devices and wherever low weight is crucial.

Due to the delicate structure of the ceramic sinter, we absolutely advise against force-fitting (so-called press-fit), as this risks chipping the coating of this precision component. To ensure stability in automation, specialized industrial adhesives 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 industrial neodymium magnets, offering a great economic balance and operational stability. If you need even stronger magnets in the same volume (Ø5x30), 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 5 mm and height 30 mm. The key parameter here is the holding force amounting to approximately 0.45 kg (force ~4.40 N), which, with such compact dimensions, proves the high power of the NdFeB material. The product has a [NiCuNi] coating, which secures it against external factors, 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. 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 Nd₂Fe₁₄B magnets.

Strengths

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

They retain magnetic properties for around ten years – the drop is just ~1% (according to analyses),
They are noted for resistance to demagnetization induced by external disturbances,
A magnet with a smooth gold surface is more attractive,
They are known for high magnetic induction at the operating surface, which affects their effectiveness,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
Thanks to the option of precise forming and adaptation to specialized projects, NdFeB magnets can be produced in a wide range of geometric configurations, which amplifies use scope,
Key role in electronics industry – they are utilized in computer drives, electromotive mechanisms, medical devices, also technologically advanced constructions.
Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,

Cons

Disadvantages of neodymium magnets:

They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also increases its resistance to damage
Neodymium magnets lose their power 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 start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
We suggest a housing - magnetic holder, due to difficulties in creating nuts inside the magnet and complicated forms.
Health risk related to microscopic parts of magnets pose a threat, if swallowed, which gains importance in the context of child safety. Furthermore, tiny parts of these devices are able to complicate diagnosis medical in case of swallowing.
Due to neodymium price, their price is relatively high,

Pull force analysis

Best holding force of the magnet in ideal parameters – what it depends on?

The load parameter shown represents the maximum value, obtained under optimal environment, specifically:

with the use of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
possessing a massiveness of minimum 10 mm to avoid saturation
with a surface cleaned and smooth
with zero gap (without impurities)
for force acting at a right angle (pull-off, not shear)
in neutral thermal conditions

Determinants of practical lifting force of a magnet

Holding efficiency is affected by specific conditions, mainly (from priority):

Distance – existence of foreign body (rust, dirt, air) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
Pull-off angle – 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 adequately massive. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
Steel type – low-carbon steel gives the best results. Alloy admixtures lower magnetic permeability and holding force.
Surface finish – full contact is obtained only on smooth steel. Rough texture create air cushions, reducing force.
Temperature influence – hot environment reduces magnetic field. 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 attempts to slide the magnet the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate decreases the lifting capacity.

Warnings

Handling guide

Be careful. Rare earth magnets attract from a long distance and snap with huge force, often faster than you can react.

Cards and drives

Avoid bringing magnets close to a wallet, computer, or screen. The magnetism can irreversibly ruin these devices and wipe information from cards.

Bone fractures

Mind your fingers. Two large magnets will join immediately with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!

GPS and phone interference

Remember: neodymium magnets produce a field that confuses precision electronics. Maintain a separation from your mobile, tablet, and navigation systems.

Maximum temperature

Standard neodymium magnets (N-type) lose magnetization when the temperature exceeds 80°C. This process is irreversible.

Do not give to children

NdFeB magnets are not suitable for play. Accidental ingestion of multiple magnets may result in them connecting inside the digestive tract, which poses a direct threat to life and requires immediate surgery.

Danger to pacemakers

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

Allergic reactions

Medical facts indicate that nickel (the usual finish) is a potent allergen. If your skin reacts to metals, prevent touching magnets with bare hands and choose encased magnets.

Mechanical processing

Powder generated during grinding of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.

Protective goggles

Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
