Magnetic force decreases drastically per each millimeter of spacing. Note that even a microscopic distance (e.g., dirt, paint, dust) noticeably reduces the pull force. Magnetic products hold most effectively in perfect adhesion; air break drastically cuts the force. Notice how rapidly the pull force fall, when the magnet does not touch flatly to the metal substrate. When planning the assembly, avoid unnecessary gaps.

The table below calculates the approximate shear load required to start the downward movement of the magnet vertically on a vertical steel wall (considering standard friction). This value is relative to the separation distance between the magnet and the surface.

When placing a holder on a upright plane (e.g., a car body), it will only hold just about 1/5 of its nominal power. Gravitational force and a weak degree of grip mean that holders slide down faster than they detach. Planning a hanger? Note that the shear force is noticeably lower than the perpendicular breakaway force. On a painted metal, the element will slip down under a much lighter cargo. Application of an anti-slip pad can effectively raise the stability.

A too thin steel is incapable of absorb the full magnetic flux, which wastes potential of the holder. If you attach a powerful product to a thin surface, the magnetism will penetrate right through and the attraction force will be weaker. To achieve the maximum of this neodymium's power, you need a suitably thick backing of metal. The material oversaturation causes that on thin elements (e.g., car bodies), the magnet holds weaker. We suggest choosing the steel dimension from these parameters.

Classic neodymiums lose power past the thermal threshold. Watch out for overheating – heat can irreversibly demagnetize this product. With increasing heat, the magnet's capacity temporarily decreases. Do not use this magnet close to heaters higher than its operating temperature limit. Exceeding the critical threshold will lead to destruction of magnetic properties.

*Engineering note: Temperature resistance depends not only on the material grade, and the Permeance Coefficient Pc. Thin magnets (low permeance coefficient) may lose charge permanently sooner than long magnets. Warning indicator in the table signals a risk of irreversible loss for this specific geometry.

Two strong neodymiums attract each other from a much further distance than a magnet and steel setup. The setup of two magnets creates a more powerful interaction and a wider radius of performance. Want to build a strong closure? Utilize two neodymiums instead of a neodymium and a steel. Exercise caution that when connecting a pair of magnets, the impact force is massive. The levitation is a bit weaker than the connection force, but still significant.
*Field value between like poles reaches ~0 Gs at the geometric center of the gap (caused by magnetic field nullification).
Important: Estimates demonstrate friction force of dual matching neodymium magnets (friction ~0.15 for Ni-Ni layer).

Powerful magnet radiation is a serious hazard to IT equipment as well as medical implants. These magnets produce a flux that destroys function of digital equipment. Notice: the unseen radiation penetrates the body and plastic. Increased vigilance must be taken by people with cochlear implants and insulin pumps. The risk also applies to: mechanical watches, car keys, speakers, and displays. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

NdFeB products are delicate – a violent impact against metal causes immediate chipping. Pay attention to connection velocity – a neodymium left loose turns into a projectile. Impact energy can cause material chips or painful pinches to skin. Always hold the magnet during bringing near metal so it doesn't hit with great force against the steel surface. A collision at high speed means shattering of the magnet. Wear safety glasses when playing with large magnets.

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

1. Sliding resistance

*Warning: On a vertical surface, the magnet holds just a fraction of its max power.

2. Steel saturation

*Thin metal sheet (e.g. 0.5mm PC 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) = 0.82

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 incredibly powerful cylindrical magnet, made from durable NdFeB material, which, with dimensions of Ø70x60 mm, guarantees the highest energy density. The MW 70x60 / N38 component features an accuracy of ±0.1mm and industrial build quality, making it a perfect solution for professional engineers and designers. As a magnetic rod with significant force (approx. 163.93 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring rapid order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.

It successfully proves itself in modeling, advanced robotics, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 1608.16 N with a weight of only 1731.8 g, this cylindrical magnet is indispensable in miniature devices and wherever every gram matters.

Due to the brittleness of the NdFeB material, we absolutely advise against force-fitting (so-called press-fit), as this risks chipping the coating of this professional component. To ensure stability in industry, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.

Grade N38 is the most frequently chosen 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 (Ø70x60), 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 70 mm and height 60 mm. The key parameter here is the holding force amounting to approximately 163.93 kg (force ~1608.16 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 cylinder is magnetized axially (along the height of 60 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 through the diameter if your project requires it.

Strengths as well as weaknesses of rare earth magnets.

Advantages

Besides their high retention, neodymium magnets are valued for these benefits:

Their magnetic field is maintained, and after approximately ten years it decreases only by ~1% (theoretically),
They possess excellent resistance to magnetism drop due to opposing magnetic fields,
A magnet with a shiny nickel surface looks better,
Magnets exhibit extremely high magnetic induction on the outer side,
Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
In view of the option of flexible forming and customization to individualized requirements, NdFeB magnets can be created in a wide range of shapes and sizes, which makes them more universal,
Wide application in modern industrial fields – they are used in computer drives, electric drive systems, medical devices, also complex engineering applications.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Weaknesses

Disadvantages of NdFeB magnets:

Brittleness is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a strong case, which not only secures them against impacts but also raises 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 force. 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.
Limited possibility of making nuts in the magnet and complex forms - preferred is casing - mounting mechanism.
Health risk to health – tiny shards of magnets pose a threat, when accidentally swallowed, which becomes key in the context of child safety. Additionally, tiny parts of these magnets can be problematic in diagnostics medical when they are in the body.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Holding force characteristics

Maximum magnetic pulling force – what it depends on?

The declared magnet strength represents the limit force, obtained under optimal environment, specifically:

with the application of a yoke made of low-carbon steel, ensuring full magnetic saturation
with a cross-section of at least 10 mm
with a surface free of scratches
without any air gap between the magnet and steel
under axial force direction (90-degree angle)
at temperature approx. 20 degrees Celsius

Practical aspects of lifting capacity – factors

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

Distance (between the magnet and the plate), as even a tiny clearance (e.g. 0.5 mm) can cause a drastic drop in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
Base massiveness – insufficiently thick sheet does not accept the full field, causing part of the power to be lost into the air.
Steel type – mild steel gives the best results. Alloy admixtures decrease magnetic permeability and holding force.
Surface condition – ground elements ensure maximum contact, which improves force. Rough surfaces weaken the grip.
Thermal conditions – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).

Lifting capacity was assessed using a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, however under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate decreases the load capacity.

People with a heart stimulator should keep an safe separation from magnets. The magnetism can stop the operation of the life-saving device.

Crushing risk

Protect your hands. Two large magnets will snap together instantly with a force of massive weight, crushing anything in their path. Exercise extreme caution!

Nickel allergy

Certain individuals have a contact allergy to nickel, which is the typical protective layer for NdFeB magnets. Prolonged contact may cause skin redness. We strongly advise use safety gloves.

Shattering risk

Neodymium magnets are ceramic materials, meaning they are prone to chipping. Clashing of two magnets will cause them shattering into small pieces.

Permanent damage

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

Danger to the youngest

Product intended for adults. Small elements can be swallowed, causing serious injuries. Store out of reach of children and animals.

Dust is flammable

Mechanical processing of NdFeB material poses a fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.

Protect data

Avoid bringing magnets close to a purse, computer, or screen. The magnetic field can permanently damage these devices and wipe information from cards.

Keep away from electronics

An intense magnetic field interferes with the functioning of magnetometers in smartphones and GPS navigation. Keep magnets close to a device to prevent damaging the sensors.

Caution required

Use magnets with awareness. Their powerful strength can surprise even professionals. Plan your moves and do not underestimate their force.
