Magnetic force decreases significantly per each millimeter of distance. Remember that even a microscopic distance (e.g., contamination, varnish, dust) noticeably weakens the grip. Magnetic products operate most effectively during direct contact; air break weakens the force. Analyze how flashily the parameters fall, when the magnet does not touch directly to the steel surface. When designing the assembly, discard additional spacers.

This section calculates the estimated force needed to initiate the slippage of the magnet down along a vertical metal surface (considering standard friction coefficient). This value is a function of the separation distance between the magnet and the metal.

When hanging a holder on a upright plane (e.g., a car body), it will only hold just about 20%-30% of its nominal power. Gravitational force and a low friction coefficient influence the fact that magnets slip easier than they pull off. Planning a wall mount? Remember that the shear force is significantly lower than the perpendicular breakaway force. On a smooth steel, the holder will give way down under a much lighter weight. Using a rubber pad can drastically raise the stability.

A thin metal plate cannot conduct the entire magnetic field, which wastes potential of the holder. If you install a neodymium to a too thin substrate, the flux will penetrate right through and the attraction force will be weaker. To achieve full efficiency of this neodymium's power, you need a suitably thick piece of steel. The saturation effect means that on delicate walls (e.g., appliance housings), the holder shows lower pull force. We advise picking the steel cross-section according to the table below.

Ordinary NdFeB products change their properties power after exceeding the maximum temperature. Watch out for overheating – heat can permanently destroy this magnet. With increasing heat, the magnet's power momentarily decreases. Avoid using this magnet in hot environments higher than its safe range. Too high temperature will result in irreversible degradation of magnetism.

*Engineering note: Heat tolerance depends not only on the material grade, and the Permeance Coefficient Pc. Thin magnets (low permeance coefficient) are more susceptible to demagnetization sooner than long magnets. Warning indicator in the table signals a risk of irreversible loss for this specific geometry.

Two strong neodymiums interact from a significantly greater distance than a magnet and steel combination. The setup of two magnets generates a stronger field and a further horizon of action. Designing a strong closure? Utilize two neodymiums instead of a neodymium and a steel. Remember that when attracting two neodymiums, the collision energy is huge. The levitation is a bit weaker than the connection force, but still large.
*The magnetic induction for N-N configuration drops to ~0 Gs at the midpoint between the magnets (resulting from vector opposition).
Important: Calculations show friction force of a pair of matching magnets (friction ~0.15 for Ni-Ni layer).

Powerful magnet radiation poses a large risk to electronics and medical implants. These magnets produce a field that destroys function of digital equipment. Remember: the invisible magnetic field passes through tissues and plastic. Special caution must be exercised by people with hearing aids and insulin pumps. Influence will be felt by: mechanical watches, car keys, speakers, and screens. Avoid contact with magnetic cards, HDD media, or sensitive navigation tools.

NdFeB products are prone to chipping – a strong collision with metal risks their cracking. Control the attraction moment – a magnet released freely becomes dangerous. Kinetic force can destroy the magnet or painful pinches to fingers. Always hold the magnet during bringing near metal so it doesn't hit violently against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Wear eye protection when playing with powerful specimens.

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. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Shear force

*Warning: On a vertical surface, the magnet retains merely approx. 20-30% of its perpendicular strength.

2. Steel thickness impact

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

3. Thermal stability

*For N38 grade, the max working temp is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.14

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.

This product is an exceptionally strong cylinder magnet, composed of advanced NdFeB material, which, with dimensions of Ø38x3.5 mm, guarantees the highest energy density. This specific item features a tolerance of ±0.1mm and industrial build quality, making it an ideal solution for the most demanding engineers and designers. As a cylindrical magnet with impressive force (approx. 5.09 kg), this product is in stock from our European logistics center, ensuring rapid order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

It successfully proves itself in modeling, advanced automation, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 49.91 N with a weight of only 29.77 g, this cylindrical magnet is indispensable in miniature devices 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., 38.1 mm) using two-component epoxy glues. To ensure stability in industry, 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 professional neodymium magnets, offering a great economic balance and high resistance to demagnetization. If you need the strongest magnets in the same volume (Ø38x3.5), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.

The presented product is a neodymium magnet with precisely defined parameters: diameter 38 mm and height 3.5 mm. The key parameter here is the lifting capacity amounting to approximately 5.09 kg (force ~49.91 N), which, with such compact 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 rod magnet is magnetized axially (along the height of 3.5 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 diametrically if your project requires it.

Strengths as well as weaknesses of neodymium magnets.

Advantages

Besides their durability, neodymium magnets are valued for these benefits:

They have stable power, and over nearly 10 years their attraction force decreases symbolically – ~1% (according to theory),
They have excellent resistance to magnetic field loss as a result of opposing magnetic fields,
A magnet with a metallic nickel surface has better aesthetics,
Neodymium magnets achieve maximum magnetic induction on a small surface, which allows for strong attraction,
Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
Considering the potential of flexible shaping and adaptation to individualized needs, magnetic components can be modeled in a wide range of shapes and sizes, which amplifies use scope,
Versatile presence in innovative solutions – they serve a role in hard drives, brushless drives, advanced medical instruments, as well as technologically advanced constructions.
Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,

Limitations

Characteristics of disadvantages of neodymium magnets: application proposals

To avoid cracks under impact, we recommend using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
Magnets exposed to a humid environment can rust. Therefore during using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
Limited ability of making nuts in the magnet and complex shapes - recommended is cover - magnetic holder.
Health risk resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child safety. It is also worth noting that small elements of these magnets are able to be problematic in diagnostics medical after entering the body.
With large orders the cost of neodymium magnets is economically unviable,

Lifting parameters

Optimal lifting capacity of a neodymium magnet – what contributes to it?

The force parameter is a theoretical maximum value conducted under specific, ideal conditions:

using a base made of mild steel, serving as a circuit closing element
whose transverse dimension is min. 10 mm
with a surface free of scratches
under conditions of ideal adhesion (surface-to-surface)
under axial application of breakaway force (90-degree angle)
at standard ambient temperature

Lifting capacity in real conditions – factors

In real-world applications, the actual holding force results from a number of factors, listed from most significant:

Gap between surfaces – every millimeter of separation (caused e.g. by varnish or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
Angle of force application – maximum parameter is available only during perpendicular pulling. The resistance to sliding of the magnet along the surface is standardly several times smaller (approx. 1/5 of the lifting capacity).
Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
Material type – the best choice is high-permeability steel. Hardened steels may attract less.
Surface quality – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
Heat – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).

Lifting capacity was assessed with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, whereas under attempts to slide the magnet the holding force is lower. Additionally, even a small distance between the magnet and the plate reduces the holding force.

H&S for magnets

Pinching danger

Big blocks can break fingers in a fraction of a second. Under no circumstances put your hand between two attracting surfaces.

Protect data

Powerful magnetic fields can corrupt files on payment cards, hard drives, and other magnetic media. Stay away of at least 10 cm.

Compass and GPS

An intense magnetic field negatively affects the functioning of compasses in phones and GPS navigation. Do not bring magnets close to a device to avoid damaging the sensors.

Danger to pacemakers

Life threat: Strong magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.

Allergic reactions

Certain individuals experience a contact allergy to Ni, which is the standard coating for neodymium magnets. Prolonged contact might lead to skin redness. We strongly advise use safety gloves.

Risk of cracking

Despite the nickel coating, the material is delicate and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.

Fire warning

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

Heat warning

Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will ruin its magnetic structure and strength.

Danger to the youngest

Neodymium magnets are not toys. Accidental ingestion of several magnets may result in them pinching intestinal walls, which poses a direct threat to life and necessitates immediate surgery.

Do not underestimate power

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