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.

Magnetic force drops sharply with every mm of gap. Remember that even a microscopic distance (e.g., dirt, varnish, veneer) noticeably diminishes the holding power. Magnetic products operate strongest in perfect adhesion; gap drastically cuts the force. Notice how quickly the pull force plummet, when the product does not touch flatly to the steel surface. When calculating the assembly, eliminate unnecessary gaps.

This section shows the approximate weight limit needed to start the slippage of the magnet down against a vertical steel plate (considering typical friction coefficient). The holding force varies with the separation distance between the magnet and the surface.

When mounting a element on a vertical plane (e.g., a board), it will maintain only about 1/5 of nominal attraction strength. Gravitational force and a low friction coefficient mean that holders move down faster than they pop off the substrate. Want to create a hanger? Remember that the shear force is significantly lower than the perpendicular breakaway force. On a smooth steel, the holder will give way down under a much lighter cargo. Using a rubber pad can significantly increase the grip.

A thin metal plate is incapable of absorb the entire magnetic field, which wastes potential of the magnet. If you attach a powerful product to a too thin substrate, the magnetism will penetrate right through and the holding will be smaller. To achieve the maximum of this magnet's power, you need a suitably thick backing of metal. The saturation effect causes that on sheet metal structures (e.g., appliance housings), the product holds weaker. We recommend selecting the steel dimension based on the following data.

Classic neodymiums change their properties parameters above the temperature limit. Avoid high temperatures – high temperature can irreversibly destroy this product. With increasing heat, the neodymium's power temporarily drops. Avoid using this product close to ovens exceeding its operating temperature limit. Exceeding the critical threshold will lead to permanent loss of magnetic properties.
*Technical advisory: Temperature resistance is determined by both grade, and the Permeance Coefficient Pc. Thin magnets (pancake types) risk losing magnetic properties sooner than long magnets. Red status in the table signals permanent field degradation for this particular item.

Two magnetic products interact from a much further distance than a magnet and sheet setup. The setup of two magnets generates a stronger field and a wider radius of operation. Planning to create a powerful holder? Apply two magnets instead of one magnet and a striker plate. Exercise caution that when connecting a pair of magnets, the pinch force is extreme. The repulsion force is slightly lower than the connection force, but still large.
*Flux density in repulsion mode is approximately ~0 Gs at the midpoint of the gap (caused by magnetic field nullification).
Note: Estimates show friction force of dual same magnets (friction ~0.15 for Ni-Ni plating).

Extremely neodym field poses a large risk to electronic devices as well as pacemakers. These NdFeB products generate a flux that disrupts operation of sensitive medical devices. Be aware: the unseen radiation passes through tissues and plastic. Exceptional care must be taken by people with cochlear implants and drug dispensers. Influence will be felt by: automatic timepieces, car keys, speakers, and screens. Avoid contact with magnetic cards, HDD media, or sensitive navigation tools.

NdFeB products are delicate – a strong collision with metal risks their cracking. Watch the impact speed – a magnet released freely speeds with massive force. Impact energy can destroy the magnet or painful pinches to fingers. Be sure to control the product during bringing near metal so it doesn't hit violently against the steel surface. A contact at a velocity of dozens of km/h ends with a crack of the magnet. Use safety goggles when handling with large magnets.

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. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Wall mount (shear)

*Note: On a vertical wall, the magnet retains just ~20% of its perpendicular strength.

2. Efficiency vs thickness

*Thin metal sheet (e.g. computer case) drastically reduces the holding force.

3. Heat tolerance

*For standard magnets, the max working temp is 80°C.

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 1.21

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 an extremely powerful cylinder magnet, composed of modern NdFeB material, which, with dimensions of Ø10x20 mm, guarantees optimal power. The MW 10x20 / N38 model boasts high dimensional repeatability and industrial build quality, making it a perfect solution for professional engineers and designers. As a magnetic rod with significant force (approx. 2.23 kg), this product is available off-the-shelf from our European logistics center, ensuring quick order fulfillment. Furthermore, its 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 21.88 N with a weight of only 11.78 g, this cylindrical magnet is indispensable in electronics and wherever low weight is crucial.
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 precision component. To ensure stability in automation, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.
Magnets N38 are suitable for the majority of applications in automation and machine building, where extreme miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø10x20), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.
This model is characterized by dimensions Ø10x20 mm, which, at a weight of 11.78 g, makes it an element with high magnetic energy density. The value of 21.88 N means that the magnet is capable of holding a weight many times exceeding its own mass of 11.78 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 10 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.

Benefits

In addition to their long-term stability, neodymium magnets provide the following advantages:
  • They virtually do not lose power, because even after ten years the performance loss is only ~1% (in laboratory conditions),
  • Neodymium magnets are distinguished by extremely resistant to loss of magnetic properties caused by external magnetic fields,
  • The use of an elegant finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
  • They show high magnetic induction at the operating surface, making them more effective,
  • Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
  • Considering the option of free forming and adaptation to custom projects, NdFeB magnets can be modeled in a variety of geometric configurations, which amplifies use scope,
  • Versatile presence in future technologies – they serve a role in HDD drives, electric drive systems, medical equipment, also multitasking production systems.
  • Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Disadvantages

Disadvantages of neodymium magnets:
  • They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also increases its resistance to damage
  • Neodymium magnets lose force 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 oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
  • We recommend cover - magnetic mount, due to difficulties in realizing threads inside the magnet and complex shapes.
  • Possible danger resulting from small fragments of magnets are risky, in case of ingestion, 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.
  • Due to complex production process, their price is relatively high,

Lifting parameters

Maximum holding power of the magnet – what affects it?

Information about lifting capacity was defined for ideal contact conditions, taking into account:
  • with the use of a yoke made of special test steel, guaranteeing maximum field concentration
  • with a thickness minimum 10 mm
  • characterized by lack of roughness
  • under conditions of gap-free contact (surface-to-surface)
  • under axial force vector (90-degree angle)
  • in neutral thermal conditions

Practical aspects of lifting capacity – factors

Bear in mind that the magnet holding will differ influenced by the following factors, starting with the most relevant:
  • Clearance – existence of any layer (rust, dirt, gap) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
  • Force direction – catalog parameter refers to pulling vertically. When applying parallel force, the magnet exhibits much less (often approx. 20-30% of nominal force).
  • Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
  • Material type – the best choice is pure iron steel. Stainless steels may attract less.
  • Surface condition – ground elements ensure maximum contact, which improves force. Rough surfaces reduce efficiency.
  • Operating temperature – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).

Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the load capacity is reduced by as much as fivefold. In addition, even a minimal clearance between the magnet and the plate decreases the lifting capacity.

H&S for magnets
Impact on smartphones

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

Protective goggles

Beware of splinters. Magnets can explode upon uncontrolled impact, ejecting shards into the air. We recommend safety glasses.

Combustion hazard

Fire warning: Neodymium dust is explosive. Do not process magnets in home conditions as this may cause fire.

Pinching danger

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

Heat sensitivity

Monitor thermal conditions. Heating the magnet to high heat will ruin its magnetic structure and strength.

Respect the power

Handle with care. Rare earth magnets attract from a long distance and connect with huge force, often faster than you can react.

Warning for heart patients

Life threat: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have medical devices.

Cards and drives

Avoid bringing magnets close to a wallet, laptop, or TV. The magnetic field can irreversibly ruin these devices and erase data from cards.

Allergy Warning

Some people have a sensitization to nickel, which is the typical protective layer for NdFeB magnets. Frequent touching may cause skin redness. We suggest use protective gloves.

Keep away from children

NdFeB magnets are not suitable for play. Accidental ingestion of several magnets can lead to them connecting inside the digestive tract, which constitutes a direct threat to life and necessitates urgent medical intervention.
