Pulling power decreases significantly with every mm of distance. Keep in mind that every additional insulation layer (e.g., contamination, varnish, veneer) significantly reduces the pull force. Magnetic products work strongest at the point of direct contact; air break drastically cuts the force. Analyze how rapidly the parameters fall, when the product does not adhere directly to the metal substrate. When calculating the mounting, eliminate unnecessary gaps.

This section indicates the approximate shear load needed to cause the shifting of the magnet vertically against a vertical metal surface (considering typical friction coefficient). This parameter varies with the separation distance between the magnet and the metal.

When hanging a element on a upright surface (e.g., a car body), it will only hold only approx. 20%-30% of its maximum pull force. Gravitational force and a weak degree of grip influence the fact that magnets slide down faster than they detach. Want to create a hanger? Remember that the shear force is noticeably lower than the perpendicular breakaway force. On a smooth steel, the magnet will give way down under a noticeably lighter load. Application of an anti-slip layer can drastically raise the stability.

A too thin steel cannot conduct the full magnetic flux, which squanders power of the magnet. If you install a neodymium to a weak sheet, the magnetism will penetrate right through and the attraction force will be weaker. To squeeze 100% of this neodymium's potential, you require a sufficiently solid element of steel. The saturation effect causes that on sheet metal structures (e.g., appliance housings), the magnet works worse. We recommend selecting the steel cross-section from these parameters.

Ordinary NdFeB products lose power after exceeding the maximum temperature. Watch out for overheating – excessive heat can permanently demagnetize this product. With every degree above norm, the neodymium's force momentarily lowers. Do not use this magnet in hot environments higher than its safe range. Too high temperature will cause destruction of magnetism.

*Technical advisory: Temperature resistance depends not only on the material grade, as well as the dimension ratios. Flat magnets (pancake types) risk losing magnetic properties sooner than long magnets. The danger warning in the table points to permanent field degradation for this specific geometry.

Two magnets attract each other from a much further distance than a neodymium and metal setup. The setup of magnet-to-magnet creates a more powerful interaction and a larger range of action. Want to build a strong closure? Utilize two neodymiums instead of one magnet and a striker plate. Remember that when bringing together two magnets, the impact force is massive. The levitation is marginally weaker than the connection force, but still impressive.
*Field value in repulsion mode drops to ~0 Gs at the geometric center of the gap (due to field cancellation).
Important: Estimates demonstrate shear force of a pair of same magnets (friction ~0.15 for Ni-Ni coating).

Extremely neodym field is a serious hazard to electronic devices as well as medical implants. These NdFeB products generate a field that prevents correct functioning of digital equipment. Notice: the invisible magnetic field passes through tissues and housings. Special caution must be taken by people with cochlear implants and insulin pumps. Influence will be felt by: mechanical watches, remotes, speakers, and displays. Do not place the magnet near cards, hard drives, or precise measuring instruments.

Table 8: Impact energy (kinetic energy) - warning
MW 80x30 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	16.39 km/h (4.55 m/s)	11.72 J
30 mm	23.38 km/h (6.49 m/s)	23.85 J
50 mm	28.31 km/h (7.86 m/s)	34.98 J
100 mm	39.22 km/h (10.90 m/s)	67.13 J

NdFeB products are delicate – a collision with steel risks their cracking. Pay attention to connection velocity – a magnet released freely becomes dangerous. Kinetic force can destroy the magnet or painful pinches to skin. Always hold the magnet during bringing near metal so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h means shattering of the magnet. Wear safety glasses when handling with large magnets.

Water displaces steel, making heavy objects slightly lighter. However, remember the water resistance when pulling the rope quickly.

1. Sliding resistance

*Note: On a vertical surface, the magnet retains only a fraction of its max power.

2. Steel saturation

*Thin metal sheet (e.g. 0.5mm PC 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) = 0.48

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 presented product is a very strong cylindrical magnet, made from modern NdFeB material, which, with dimensions of Ø80x30 mm, guarantees maximum efficiency. The MW 80x30 / N38 component is characterized by a tolerance of ±0.1mm and industrial build quality, making it an excellent solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 170.64 kg), this product is in stock from our European logistics center, ensuring rapid order fulfillment. Furthermore, 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 generators, advanced Hall effect sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the high power of 1673.99 N with a weight of only 1130.97 g, this cylindrical magnet is indispensable in electronics and wherever low weight is crucial.

Since our magnets have a very precise dimensions, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 80.1 mm) using epoxy glues. To ensure stability in automation, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.

Magnets NdFeB grade N38 are strong enough for the majority of applications in modeling and machine building, where extreme miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø80x30), 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 Ø80x30 mm, which, at a weight of 1130.97 g, makes it an element with high magnetic energy density. The value of 1673.99 N means that the magnet is capable of holding a weight many times exceeding its own mass of 1130.97 g. 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.

Advantages as well as disadvantages of rare earth magnets.

Advantages

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

Their strength is maintained, and after approximately 10 years it decreases only by ~1% (according to research),
They have excellent resistance to weakening of magnetic properties as a result of external magnetic sources,
A magnet with a shiny nickel surface has better aesthetics,
Neodymium magnets generate maximum magnetic induction on a small area, which allows for strong attraction,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
Thanks to the option of flexible molding and customization to specialized needs, magnetic components can be created in a variety of shapes and sizes, which amplifies use scope,
Wide application in innovative solutions – they find application in computer drives, motor assemblies, advanced medical instruments, also technologically advanced constructions.
Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,

Disadvantages

Disadvantages of neodymium magnets:

They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only shields the magnet but also increases its resistance to damage
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
Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
We suggest cover - magnetic holder, due to difficulties in realizing threads inside the magnet and complex shapes.
Health risk resulting from small fragments of magnets can be dangerous, if swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, small elements of these products can disrupt the diagnostic process medical in case of swallowing.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Holding force characteristics

Maximum lifting force for a neodymium magnet – what affects it?

The load parameter shown refers to the maximum value, obtained under ideal test conditions, namely:

with the use of a sheet made of low-carbon steel, guaranteeing maximum field concentration
whose transverse dimension equals approx. 10 mm
with an polished touching surface
under conditions of no distance (metal-to-metal)
under axial application of breakaway force (90-degree angle)
in neutral thermal conditions

Key elements affecting lifting force

In practice, the actual holding force is determined by a number of factors, ranked from crucial:

Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
Material type – the best choice is pure iron steel. Cast iron may generate lower lifting capacity.
Surface quality – the more even the surface, the larger the contact zone and stronger the hold. Roughness creates an air distance.
Heat – NdFeB sinters have a negative temperature coefficient. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).

Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under perpendicular forces, in contrast under parallel forces the load capacity is reduced by as much as fivefold. In addition, even a slight gap between the magnet and the plate decreases the holding force.

Safe handling of neodymium magnets

Protect data

Do not bring magnets close to a wallet, computer, or TV. The magnetic field can irreversibly ruin these devices and wipe information from cards.

Crushing risk

Risk of injury: The pulling power is so immense that it can cause hematomas, crushing, and broken bones. Protective gloves are recommended.

Safe operation

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

Compass and GPS

Note: rare earth magnets produce a field that interferes with sensitive sensors. Maintain a safe distance from your phone, tablet, and GPS.

Product not for children

These products are not toys. Accidental ingestion of a few magnets can lead to them attracting across intestines, which poses a severe health hazard and necessitates urgent medical intervention.

Combustion hazard

Mechanical processing of NdFeB material carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.

Pacemakers

Warning for patients: Strong magnetic fields disrupt medical devices. Keep at least 30 cm distance or request help to handle the magnets.

Eye protection

NdFeB magnets are sintered ceramics, which means they are prone to chipping. Collision of two magnets leads to them breaking into shards.

Demagnetization risk

Regular neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. This process is irreversible.

Nickel coating and allergies

Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction occurs, immediately stop handling magnets and use protective gear.
