Magnetic force drops sharply with every subsequent millimeter of spacing. Note that even a very thin break (e.g., contamination, paint, rust) significantly diminishes the holding power. Magnets operate optimally during direct contact; air break kills the force. See how quickly the pull force drop, when the product does not touch directly to the metal substrate. When designing the mounting, avoid redundant distances.

The following data calculates the theoretical holding capacity needed to initiate the downward movement of the magnet vertically against a upright metal surface (considering standard friction). This parameter is relative to the separation distance between the magnet and the metal.

When mounting a magnet on a vertical wall (e.g., a fridge), it will maintain barely about 1/5 of its nominal power. Gravitational force and a weak degree of grip influence the fact that magnets slide down faster than they pull off. Planning a hanger? Consider that the sliding force is significantly lower than the maximum static pull force. On a painted metal, the element will give way down under a much lighter cargo. Application of an anti-slip pad can drastically raise the stability.

A too thin steel is not enough to absorb the full magnetic flux, 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 attraction force will be weaker. To utilize 100% of this magnet's potential, you need a suitably thick element of steel. The material oversaturation means that on sheet metal structures (e.g., car bodies), the product holds weaker. We advise picking the steel dimension from these parameters.

Ordinary NdFeB products lose power after exceeding the maximum temperature. Protect against heat – excessive heat can irreversibly destroy this magnet. As the temperature rises, the magnet's capacity briefly lowers. Do not use this magnet close to ovens higher than its operating temperature limit. Ignoring the limit will lead to destruction of magnetism.

*Engineering note: Heat tolerance depends not only on the material grade, and the Permeance Coefficient Pc. Low-profile magnets (low permeance coefficient) may lose charge permanently under lower heat stress compared to rod magnets. Warning indicator in the table indicates a risk of irreversible loss for this specific geometry.

Two magnets attract each other from a much further distance than a neodymium and metal setup. The setup of two magnets produces a massive flux and a wider radius of action. Want to build a powerful holder? Use a pair of magnets instead of a neodymium and a striker plate. Remember that when attracting two neodymiums, the impact force is huge. The repulsion force is marginally weaker than the attraction, but still impressive.
*Flux density between like poles reaches ~0 Gs at the geometric center of the gap (due to field cancellation).
Note: Estimates show friction force of a pair of same magnets (friction coefficient ~0.15 for Ni-Ni coating).

Powerful magnet radiation is a large risk to IT equipment and pacemakers. These NdFeB products generate a flux that destroys function of digital equipment. Remember: the unseen radiation passes through tissues and plastic. Increased vigilance must be taken by people with cochlear implants and drug dispensers. Influence will be felt by: mechanical watches, car keys, membranes, and screens. Do not bring the product near payment cards, HDD media, or precise measuring instruments.

Neodymium magnets are very brittle – a violent impact against metal can result in shattering. Pay attention to connection velocity – a magnet released freely speeds with massive force. Striking energy can cause material chips or dangerous crushing to fingers. Hold the magnet firmly during mounting so it doesn't hit violently against the metal. A collision at high speed means shattering of the magnet. Use safety goggles when working with powerful specimens.

The magnetic field penetrates through water without any losses. However, remember the water resistance when pulling the rope quickly.

1. Shear force

*Caution: On a vertical wall, the magnet holds just ~20% of its nominal pull.

2. Plate thickness effect

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

3. Thermal stability

*For standard magnets, 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) = 0.74

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 an extremely powerful cylindrical magnet, produced from modern NdFeB material, which, at dimensions of Ø70x50 mm, guarantees maximum efficiency. This specific item boasts a tolerance of ±0.1mm and industrial build quality, making it an ideal solution for professional engineers and designers. As a magnetic rod with significant force (approx. 168.21 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring rapid order fulfillment. Moreover, its 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 fastening or actuating element. Thanks to the pull force of 1650.14 N with a weight of only 1443.17 g, this cylindrical magnet is indispensable in miniature devices and wherever every gram matters.

Due to the brittleness of the NdFeB material, you must not use force-fitting (so-called press-fit), as this risks immediate cracking of this professional component. 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 industrial neodymium magnets, offering a great economic balance and operational stability. If you need the strongest magnets in the same volume (Ø70x50), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

The presented product is a neodymium magnet with precisely defined parameters: diameter 70 mm and height 50 mm. The value of 1650.14 N means that the magnet is capable of holding a weight many times exceeding its own mass of 1443.17 g. The product has a [NiCuNi] coating, which protects the surface against oxidation, giving it an aesthetic, silvery shine.

Standardly, the magnetic axis runs through the center of the cylinder, causing the greatest attraction force to occur on the bases with a diameter of 70 mm. 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 as well as cons of neodymium magnets.

Advantages

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

They retain magnetic properties for almost 10 years – the drop is just ~1% (in theory),
Neodymium magnets are distinguished by exceptionally resistant to loss of magnetic properties caused by magnetic disturbances,
The use of an elegant finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
The surface of neodymium magnets generates a powerful magnetic field – this is one of their assets,
Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
Considering the ability of flexible shaping and adaptation to custom needs, magnetic components can be manufactured in a variety of shapes and sizes, which expands the range of possible applications,
Wide application in electronics industry – they are used in mass storage devices, brushless drives, medical devices, and industrial machines.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which enables their usage in miniature devices

Disadvantages

Cons of neodymium magnets: weaknesses and usage proposals

They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
When exposed to high temperature, neodymium magnets experience 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
When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
Due to limitations in creating threads and complex shapes in magnets, we recommend using casing - magnetic mount.
Possible danger related to microscopic parts of magnets can be dangerous, if swallowed, which becomes key in the context of child safety. It is also worth noting that small components of these magnets are able to be problematic in diagnostics medical in case of swallowing.
High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities

Lifting parameters

Maximum holding power of the magnet – what it depends on?

Breakaway force was determined for ideal contact conditions, taking into account:

on a base made of structural steel, effectively closing the magnetic flux
with a cross-section no less than 10 mm
with a plane perfectly flat
with total lack of distance (without impurities)
under axial force vector (90-degree angle)
at conditions approx. 20°C

Key elements affecting lifting force

Bear in mind that the application force will differ depending on elements below, in order of importance:

Air gap (between the magnet and the plate), since even a very small clearance (e.g. 0.5 mm) leads to a drastic drop in force by up to 50% (this also applies to varnish, rust or debris).
Load vector – highest force is reached only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is usually several times lower (approx. 1/5 of the lifting capacity).
Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
Material type – the best choice is high-permeability steel. Stainless steels may attract less.
Surface structure – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Roughness acts like micro-gaps.
Thermal conditions – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and in frost gain strength (up to a certain limit).

Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under perpendicular forces, however under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the load capacity.

Safe handling of neodymium magnets

Demagnetization risk

Regular neodymium magnets (N-type) lose magnetization when the temperature goes above 80°C. The loss of strength is permanent.

For implant holders: Strong magnetic fields disrupt medical devices. Maintain minimum 30 cm distance or ask another person to handle the magnets.

Conscious usage

Handle magnets with awareness. Their huge power can shock even experienced users. Plan your moves and do not underestimate their force.

Beware of splinters

NdFeB magnets are sintered ceramics, meaning they are very brittle. Collision of two magnets will cause them breaking into shards.

Precision electronics

Navigation devices and mobile phones are highly susceptible to magnetism. Direct contact with a strong magnet can ruin the internal compass in your phone.

No play value

Always store magnets away from children. Ingestion danger is high, and the effects of magnets clamping inside the body are very dangerous.

Threat to electronics

Device Safety: Strong magnets can ruin payment cards and delicate electronics (heart implants, medical aids, mechanical watches).

Metal Allergy

Allergy Notice: The nickel-copper-nickel coating contains nickel. If redness occurs, cease handling magnets and use protective gear.

Fire risk

Fire warning: Rare earth powder is explosive. Avoid machining magnets in home conditions as this risks ignition.

Finger safety

Big blocks can break fingers in a fraction of a second. Never put your hand betwixt two attracting surfaces.
