Frequently asked questions

What is the maximum working temperature of a disc magnet?
Standard N-series grades work up to 80 °C. Grades N50, N52 and N54 have a lower limit of 60 °C, because coercivity falls as BHmax rises. Higher temperatures require the H (120 °C), SH (150 °C), UH (180 °C), EH (200 °C) or AH (230 °C) series. Within the working range the magnet loses about 0.11% of its induction per degree, and that loss is reversible.
What is the difference between N38, N42 and N52?
The number after N is the energy product BHmax. Moving from N38 to N52 raises it by several tens of percent, but the real holding force increases by roughly 20%, because force also depends on geometry and on the magnetic circuit. N52 costs about twice as much as N42, so for most mounting work N38–N42 is the best price-to-force ratio.
What is the dimensional tolerance?
±0.1 mm as standard, ±0.05 mm to order. The tolerance is stated next to the dimensions on every product page.

Grip strength weakens sharply per each millimeter of spacing. Keep in mind that even the smallest gap (e.g., dirt, varnish, dust) strongly diminishes the holding power. Neodymiums hold most effectively at the point of direct contact; distance drastically cuts the force. See how rapidly the load capacity fall, when the magnet does not touch tightly to the steel surface. When designing the arrangement, discard additional spacers.

When mounting a element on a vertical wall (e.g., a car body), it will only hold only about 20%-30% of its maximum pull force. Gravitational force and a low friction coefficient mean that holders slip faster than they pull off. Planning a vertical fastening? Remember that the shear force is noticeably lower than the maximum static pull force. On a smooth steel, the holder will slide down under a noticeably lighter load. Utilizing a rubberized pad can drastically increase the grip.

A thin metal plate is incapable of conduct the entire magnetic field, which weakens actual performance of the magnet. If you attach a powerful product to a too thin substrate, the flux will penetrate right through and the holding will be smaller. To achieve the maximum of this neodymium's power, you need a suitably thick backing of steel. The saturation effect causes that on delicate walls (e.g., car bodies), the product works worse. We advise picking the steel dimension from these parameters.

Ordinary NdFeB products irreversibly lose strength past the thermal threshold. Avoid high temperatures – high temperature can irreversibly demagnetize this magnet. With every degree above norm, the neodymium's power briefly lowers. Avoid using this magnet close to heaters higher than its working range. Ignoring the limit will result in permanent loss of magnetic properties.
*Engineering note: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Flat magnets (pancake types) may lose charge permanently at lower temperatures compared to rod magnets. The danger warning in the table indicates a risk of irreversible loss for this particular item.

Two strong neodymiums attract each other from a wider radius than a magnet and sheet setup. The connection of magnet-to-magnet generates a stronger field and a larger range of action. Designing a powerful holder? Utilize two neodymiums instead of one magnet and a striker plate. Exercise caution that when attracting two neodymiums, the pinch force is extreme. The repulsion force is slightly lower than the attraction, but still significant.
*Flux density for N-N configuration reaches ~0 Gs at the geometric center of the gap (resulting from vector opposition).
Important: Figures show shear force of two identical neodymium magnets (friction ~0.15 for Ni-Ni coating).

Extremely neodym field is a real danger to electronic devices and pacemakers. These magnets generate a flux that prevents correct functioning of digital equipment. Remember: the invisible magnetic field acts through matter and glass. Exceptional care must be exercised by people with hearing aids and drug dispensers. Also at risk are: mechanical watches, car keys, speakers, and screens. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

Magnetic elements are very brittle – a violent impact against metal causes immediate chipping. Control the attraction moment – a magnet released freely becomes dangerous. Kinetic force can destroy the magnet or dangerous crushing 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 working with large magnets.

Corrosion warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!
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. Shear force

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

2. Efficiency vs thickness

*Thin steel (e.g. 0.5mm PC case) severely weakens the holding force.

3. Thermal stability

*For standard magnets, the safety limit is 80°C.

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.63

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 Pc (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 Pc 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 cylinder magnet, composed of modern NdFeB material, which, with dimensions of Ø18x10 mm, guarantees optimal power. This specific item is characterized by a tolerance of ±0.1mm and professional build quality, making it an ideal solution for the most demanding engineers and designers. As a cylindrical magnet with impressive force (approx. 10.76 kg), this product is in stock from our European logistics center, ensuring quick order fulfillment. Furthermore, its Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.
This model is created for building electric motors, advanced sensors, and efficient magnetic separators, where field concentration on a small surface counts. Thanks to the high power of 105.51 N with a weight of only 19.09 g, this rod is indispensable in miniature devices and wherever low weight is crucial.
Due to the delicate structure of the ceramic sinter, you must not use force-fitting (so-called press-fit), as this risks immediate cracking of this professional component. To ensure stability in industry, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.
Magnets NdFeB grade N38 are strong enough for 90% of applications in modeling and machine building, where excessive miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø18x10), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.
The presented product is a neodymium magnet with precisely defined parameters: diameter 18 mm and height 10 mm. The value of 105.51 N means that the magnet is capable of holding a weight many times exceeding its own mass of 19.09 g. The product has a [NiCuNi] coating, which secures it against external factors, giving it an aesthetic, silvery shine.
This rod magnet is magnetized axially (along the height of 10 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 neodymium magnets.

Strengths

Apart from their strong holding force, neodymium magnets have these key benefits:
  • Their power is durable, and after approximately 10 years it decreases only by ~1% (according to research),
  • They are extremely resistant to demagnetization induced by external field influence,
  • By applying a lustrous layer of gold, the element has an elegant look,
  • They are known for high magnetic induction at the operating surface, making them more effective,
  • Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
  • In view of the potential of free shaping and adaptation to custom needs, NdFeB magnets can be manufactured in a variety of forms and dimensions, which increases their versatility,
  • Wide application in future technologies – they serve a role in computer drives, drive modules, advanced medical instruments, as well as industrial machines.
  • Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,

Disadvantages

Characteristics of disadvantages of neodymium magnets and ways of using them
  • At very strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
  • NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
  • They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
  • We recommend a housing - magnetic mechanism, due to difficulties in creating threads inside the magnet and complex shapes.
  • Possible danger to health – tiny shards of magnets are risky, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, tiny parts of these magnets are able to complicate diagnosis medical after entering the body.
  • High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities

Holding force characteristics

Maximum holding power of the magnet – what affects it?

Holding force of 10.76 kg is a theoretical maximum value conducted under specific, ideal conditions:
  • with the contact of a yoke made of special test steel, guaranteeing maximum field concentration
  • whose thickness equals approx. 10 mm
  • with a plane free of scratches
  • under conditions of ideal adhesion (metal-to-metal)
  • under axial application of breakaway force (90-degree angle)
  • in stable room temperature

Determinants of lifting force in real conditions

In practice, the actual holding force is determined by a number of factors, ranked from the most important:
  • Distance – the presence of foreign body (rust, dirt, air) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
  • Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
  • Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
  • Material type – ideal substrate is pure iron steel. Cast iron may generate lower lifting capacity.
  • Smoothness – ideal contact is obtained only on polished steel. Rough texture create air cushions, reducing force.
  • Thermal environment – heating the magnet causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity was assessed with the use of a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular pulling force, however under shearing force the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet and the plate decreases the lifting capacity.

Warnings
Machining danger

Fire hazard: Neodymium dust is explosive. Do not process magnets in home conditions as this risks ignition.

This is not a toy

NdFeB magnets are not toys. Eating a few magnets can lead to them connecting inside the digestive tract, which constitutes a severe health hazard and necessitates urgent medical intervention.

Respect the power

Before starting, read the rules. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.

Sensitization to coating

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

Magnet fragility

Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.

Pinching danger

Protect your hands. Two large magnets will join instantly with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!

Compass and GPS

Navigation devices and mobile phones are extremely susceptible to magnetism. Direct contact with a powerful NdFeB magnet can ruin the sensors in your phone.

Medical interference

For implant holders: Powerful magnets affect medical devices. Keep at least 30 cm distance or ask another person to work with the magnets.

Data carriers

Very strong magnetic fields can corrupt files on payment cards, hard drives, and storage devices. Stay away of min. 10 cm.

Heat warning

Standard neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. Damage is permanent.
