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 decreases significantly with every subsequent millimeter of gap. Note that even a microscopic distance (e.g., dirt, paint, rust) noticeably diminishes the holding power. Magnets operate strongest in perfect adhesion; gap kills the force. See how quickly the parameters fall, when the magnet does not touch flatly to the steel surface. When calculating the mounting, avoid unnecessary gaps.

The following data shows the theoretical weight limit required to initiate the shifting of the magnet down against a vertical steel wall (assuming typical friction). This value varies with the separation distance between the magnet and the surface.

When mounting a element on a vertical wall (e.g., a car body), it you can count on just about 20%-30% of its nominal power. Gravitational force as well as a low friction coefficient cause that holders slip faster than they pop off the substrate. Designing a hanger? Remember that the sliding force is significantly lower than the perpendicular breakaway force. On a painted metal, the holder will slide down under a noticeably lighter load. Using a rubber pad can significantly increase the grip.

A thin metal plate is not enough to take in the entire magnetic field, which wastes potential of the magnet. If you attach a powerful product to a weak sheet, the field will penetrate right through and the attraction force will be weaker. To achieve 100% of this neodymium's power, you need a suitably thick element of steel. The saturation effect causes that on sheet metal structures (e.g., appliance housings), the holder works worse. We suggest choosing the steel cross-section from these parameters.

Ordinary NdFeB products change their properties strength above the temperature limit. Avoid high temperatures – heat can permanently destroy this magnet. As the temperature rises, the magnet's power briefly lowers. Avoid using this magnet close to ovens exceeding its working range. Too high temperature will lead to destruction of magnetic properties.
*Important note: Heat tolerance depends not only on the material grade, but also on the magnet's shape. Low-profile magnets (pancake types) may lose charge permanently sooner than long magnets. The danger warning in the table points to permanent field degradation for this particular item.

Two magnetic products attract each other from a significantly greater distance than a magnet and steel setup. Such a system of magnet-to-magnet generates a stronger field and a larger range of operation. Designing a powerful holder? Apply two magnets instead of one magnet and a steel. Remember that when attracting two neodymiums, the impact force is extreme. The repulsion force is slightly lower than the attraction, but still significant.
*Flux density between like poles drops to ~0 Gs in the exact middle of the gap (caused by magnetic field nullification).
Note: Figures show sliding force of a pair of matching neodymium magnets (friction ~0.15 for Ni-Ni coating).

Powerful magnet radiation poses a serious hazard to electronics as well as pacemakers. These NdFeB products generate a field that prevents correct functioning of sensitive medical devices. Be aware: the invisible magnetic field penetrates the body and glass. Special caution must be exercised by people with hearing aids and insulin pumps. Also at risk are: automatic timepieces, car keys, membranes, and screens. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

NdFeB products are very brittle – a violent impact against metal risks their cracking. Pay attention to connection velocity – a magnet released freely becomes dangerous. Impact energy can trigger coating fragments or injury to fingers. 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 ends with a crack of the neodymium. Use safety goggles when handling with large magnets.

Warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.
In water, the magnet feels stronger thanks to Archimedes' principle. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Sliding resistance

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

2. Efficiency vs thickness

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

3. Heat tolerance

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

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.44

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 rod magnet, composed of advanced NdFeB material, which, at dimensions of Ø9x3 mm, guarantees maximum efficiency. This specific item features high dimensional repeatability and industrial build quality, making it an ideal solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 1.94 kg), this product is available off-the-shelf from our European logistics center, ensuring lightning-fast order fulfillment. Additionally, its Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.
This model is ideal for building generators, advanced sensors, and efficient magnetic separators, where field concentration on a small surface counts. Thanks to the high power of 18.99 N with a weight of only 1.43 g, this rod is indispensable in miniature devices 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 professional component. To ensure long-term durability 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 (Ø9x3), 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 9 mm and height 3 mm. The value of 18.99 N means that the magnet is capable of holding a weight many times exceeding its own mass of 1.43 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 9 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.

Advantages and disadvantages of neodymium magnets.

Strengths

Besides their remarkable magnetic power, neodymium magnets offer the following advantages:
  • They have unchanged lifting capacity, and over nearly 10 years their performance decreases symbolically – ~1% (in testing),
  • They do not lose their magnetic properties even under strong external field,
  • A magnet with a shiny nickel surface has better aesthetics,
  • The surface of neodymium magnets generates a powerful magnetic field – this is a key feature,
  • Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling functioning at temperatures approaching 230°C and above...
  • Possibility of precise forming and modifying to concrete needs,
  • Universal use in modern industrial fields – they are used in hard drives, electric drive systems, medical equipment, and modern systems.
  • Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which makes them useful in miniature devices

Cons

Disadvantages of neodymium magnets:
  • At strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
  • Neodymium 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
  • When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
  • Limited possibility of creating threads in the magnet and complex shapes - preferred is a housing - mounting mechanism.
  • Possible danger to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which is particularly important in the context of child safety. Additionally, small elements of these devices are able to be problematic in diagnostics medical when they are in the body.
  • With large orders the cost of neodymium magnets is economically unviable,

Lifting parameters

Breakaway strength of the magnet in ideal conditions – what affects it?

The declared magnet strength represents the peak performance, obtained under optimal environment, meaning:
  • on a plate made of mild steel, perfectly concentrating the magnetic flux
  • with a thickness of at least 10 mm
  • with a surface cleaned and smooth
  • without the slightest clearance between the magnet and steel
  • under vertical force direction (90-degree angle)
  • in neutral thermal conditions

Key elements affecting lifting force

Effective lifting capacity impacted by working environment parameters, such as (from priority):
  • Distance – the presence of foreign body (rust, dirt, air) acts as an insulator, which reduces capacity rapidly (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 maximum value.
  • Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of generating force.
  • Material type – ideal substrate is high-permeability steel. Stainless steels may attract less.
  • Base smoothness – the more even the surface, the better the adhesion and stronger the hold. Roughness acts like micro-gaps.
  • Operating temperature – NdFeB sinters have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity testing was performed on a smooth plate of optimal thickness, under a perpendicular pulling force, however under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a slight gap between the magnet and the plate decreases the load capacity.

Precautions when working with NdFeB magnets
Choking Hazard

Only for adults. Tiny parts can be swallowed, leading to severe trauma. Store away from kids and pets.

Serious injuries

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

Electronic devices

Device Safety: Strong magnets can ruin payment cards and sensitive devices (heart implants, hearing aids, timepieces).

Handling rules

Handle magnets consciously. Their immense force can surprise even experienced users. Plan your moves and respect their force.

Machining danger

Machining of neodymium magnets carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.

Allergic reactions

It is widely known that the nickel plating (standard magnet coating) is a potent allergen. For allergy sufferers, prevent direct skin contact and select versions in plastic housing.

Power loss in heat

Do not overheat. NdFeB magnets are susceptible to heat. If you require resistance above 80°C, ask us about HT versions (H, SH, UH).

Risk of cracking

Neodymium magnets are sintered ceramics, which means they are prone to chipping. Impact of two magnets will cause them shattering into shards.

Magnetic interference

Navigation devices and mobile phones are extremely susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can permanently damage the sensors in your phone.

Warning for heart patients

People with a heart stimulator must keep an absolute distance from magnets. The magnetism can stop the functioning of the implant.
