Pulling power drops significantly with every subsequent millimeter of gap. Remember that every additional insulation layer (e.g., contamination, varnish, dust) significantly weakens the grip. Neodymiums hold most effectively in perfect adhesion; gap nullifies the power. Notice how flashily the parameters plummet, when the product does not adhere tightly to the metal substrate. When calculating the assembly, discard additional spacers.

The table below shows the estimated shear load needed to start the downward movement of the magnet down along a vertical metal surface (assuming standard friction coefficient). The holding force varies with the air gap between the magnet and the surface.

When mounting a element on a upright wall (e.g., a car body), it will maintain only about 1/5 of nominal attraction strength. Gravitational force as well as a weak degree of grip mean that magnets slip easier than they pull off. Planning a wall mount? Note that the shear force is much weaker than the perpendicular breakaway force. On a smooth steel, the element will give way down under a noticeably lighter cargo. Using a rubber layer can drastically increase the grip.

A thin sheet is unable to focus the full magnetic flux, which squanders power of the magnet. Should you install a neodymium to a thin surface, the field will pass right through and the attraction force will be weaker. To squeeze 100% of this neodymium's potential, you need a suitably thick element of steel. The saturation phenomenon causes that on thin elements (e.g., car bodies), the holder shows lower pull force. We advise picking the steel thickness based on the following data.

Ordinary NdFeB products lose strength above the temperature limit. Avoid high temperatures – heat can permanently damage this product. With every degree above norm, the magnet's capacity temporarily drops. Avoid using this product in hot environments higher than its safe range. Ignoring the limit will result in permanent loss of magnetic properties.

*Important note: Heat tolerance depends not only on the material grade, but also on the magnet's shape. Flat magnets (pancake types) are more susceptible to demagnetization at lower temperatures compared to rod magnets. The danger warning in the table signals permanent field degradation for this particular item.

Two strong neodymiums attract each other from a much further distance than a magnet and sheet setup. The connection of magnet-to-magnet creates a more powerful interaction and a larger range of operation. Designing a solid fastener? Apply two magnets instead of a neodymium and a steel. Be careful that when connecting a pair of magnets, the pinch force is huge. The levitation is a bit weaker than the connection force, but still significant.
*Flux density in repulsion mode reaches ~0 Gs in the exact middle of the gap (caused by magnetic field nullification).
Important: Results show shear force of two same neodymium magnets (friction ~0.15 for Ni-Ni plating).

A strong magnetic field poses a serious hazard to IT equipment and medical implants. These magnets generate a flux that disrupts operation of sensitive medical devices. Be aware: the invisible magnetic field acts through matter and plastic. Exceptional care must be taken by people with hearing aids and insulin pumps. The risk also applies to: mechanical watches, remotes, membranes, and displays. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

Table 8: Impact energy (cracking risk) - warning
MW 70x50 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	13.97 km/h (3.88 m/s)	10.87 J
30 mm	20.06 km/h (5.57 m/s)	22.40 J
50 mm	24.70 km/h (6.86 m/s)	33.96 J
100 mm	34.46 km/h (9.57 m/s)	66.12 J

Magnetic elements are prone to chipping – a strong collision with metal risks their cracking. Watch the impact speed – a neodymium left loose becomes dangerous. Striking energy can destroy the magnet or injury to skin. Hold the magnet firmly during bringing near metal so it doesn't hit with great force against the steel surface. A collision at high speed almost guarantees destruction of the magnet. Use safety goggles when handling with powerful specimens.

Corrosion warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

Contrary to myths, water does not block the magnetic field. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Wall mount (shear)

*Caution: On a vertical wall, the magnet retains merely approx. 20-30% of its nominal pull.

2. Plate thickness effect

*Thin metal sheet (e.g. computer case) significantly weakens the holding force.

3. Temperature resistance

*For N38 grade, the safety limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.74

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 presented product is an exceptionally strong cylindrical magnet, composed of durable NdFeB material, which, at dimensions of Ø70x50 mm, guarantees the highest energy density. The MW 70x50 / N38 component is characterized by an accuracy of ±0.1mm and professional build quality, making it a perfect solution for the most demanding engineers and designers. As a magnetic rod with significant force (approx. 168.21 kg), this product is available off-the-shelf from our European logistics center, ensuring lightning-fast order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is ideal for building electric motors, advanced sensors, and efficient magnetic separators, where maximum induction on a small surface counts. Thanks to the pull force of 1650.14 N with a weight of only 1443.17 g, this rod is indispensable in electronics and wherever every gram matters.

Since our magnets have a very precise dimensions, the best method is to glue them into holes with a slightly larger diameter (e.g., 70.1 mm) using epoxy glues. To ensure stability in automation, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.

Grade N38 is the most frequently chosen standard for professional neodymium magnets, offering an optimal price-to-power ratio and operational stability. If you need even stronger magnets in the same volume (Ø70x50), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.

The presented product is a neodymium magnet with precisely defined parameters: diameter 70 mm and height 50 mm. The key parameter here is the lifting capacity amounting to approximately 168.21 kg (force ~1650.14 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 50 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 and disadvantages of rare earth magnets.

Pros

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

They retain magnetic properties for nearly 10 years – the drop is just ~1% (based on simulations),
They do not lose their magnetic properties even under close interference source,
In other words, due to the glossy surface of gold, the element gains a professional look,
Magnets are characterized by excellent magnetic induction on the surface,
Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
Thanks to flexibility in constructing and the capacity to customize to specific needs,
Fundamental importance in electronics industry – they are used in computer drives, electromotive mechanisms, diagnostic systems, as well as modern systems.
Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Weaknesses

Problematic aspects of neodymium magnets: tips and applications.

At very strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
When exposed to high temperature, neodymium magnets suffer a drop in strength. 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 usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
Due to limitations in producing threads and complicated shapes in magnets, we propose using casing - magnetic mount.
Possible danger related to microscopic parts of magnets can be dangerous, in case of ingestion, which gains importance in the aspect of protecting the youngest. Additionally, small components of these devices can be problematic in diagnostics medical in case of swallowing.
Due to complex production process, their price exceeds standard values,

Holding force characteristics

Optimal lifting capacity of a neodymium magnet – what it depends on?

Breakaway force was defined for the most favorable conditions, assuming:

using a base made of low-carbon steel, acting as a circuit closing element
with a thickness of at least 10 mm
with a surface free of scratches
without the slightest insulating layer between the magnet and steel
for force applied at a right angle (in the magnet axis)
at temperature room level

Practical aspects of lifting capacity – factors

Bear in mind that the working load will differ subject to elements below, in order of importance:

Distance – existence of foreign body (rust, dirt, gap) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
Angle of force application – maximum parameter is available only during pulling at a 90° angle. The shear force of the magnet along the surface is standardly many times lower (approx. 1/5 of the lifting capacity).
Base massiveness – too thin sheet causes magnetic saturation, causing part of the power to be lost into the air.
Plate material – mild steel gives the best results. Alloy steels reduce magnetic properties and lifting capacity.
Surface quality – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
Thermal factor – hot environment weakens magnetic field. Too high temperature can permanently damage the magnet.

Lifting capacity was assessed with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under vertically applied force, in contrast under parallel forces the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate decreases the holding force.

Safe handling of NdFeB magnets

Immense force

Exercise caution. Rare earth magnets act from a distance and connect with huge force, often faster than you can move away.

Permanent damage

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

Threat to navigation

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

Flammability

Combustion risk: Rare earth powder is highly flammable. Do not process magnets without safety gear as this risks ignition.

Nickel coating and allergies

Allergy Notice: The Ni-Cu-Ni coating contains nickel. If redness appears, immediately stop working with magnets and use protective gear.

Adults only

Neodymium magnets are not intended for children. Eating a few magnets can lead to them connecting inside the digestive tract, which constitutes a direct threat to life and requires urgent medical intervention.

Pinching danger

Large magnets can break fingers instantly. Under no circumstances put your hand between two attracting surfaces.

Keep away from computers

Intense magnetic fields can corrupt files on payment cards, hard drives, and storage devices. Maintain a gap of min. 10 cm.

Fragile material

NdFeB magnets are ceramic materials, which means they are fragile like glass. Collision of two magnets will cause them shattering into shards.

Implant safety

Individuals with a heart stimulator should maintain an safe separation from magnets. The magnetism can disrupt the operation of the life-saving device.
