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 weakens drastically per each millimeter of spacing. Remember that every additional insulation layer (e.g., contamination, varnish, rust) strongly reduces the pull force. Magnets hold strongest in perfect adhesion; gap drastically cuts the power. Observe how quickly the load capacity drop, when the product does not touch directly to the steel surface. When designing the assembly, eliminate unnecessary gaps.

The table below indicates the approximate weight limit sufficient to cause the downward movement of the magnet down on a vertical steel plate (considering typical friction coefficient). This value is a function of the distance between the magnet and the surface.

When mounting a element on a vertical surface (e.g., a fridge), it will only hold just about 1/5 of its maximum pull force. Gravity and a low friction coefficient mean that holders move down faster than they pull off. Planning a hanger? Consider that the sliding force is noticeably lower than the maximum static pull force. On a painted metal, the element will slip down under a significantly smaller load. Utilizing a rubberized pad can significantly improve the result.

A thin metal plate is incapable of conduct the entire magnetic field, which wastes potential of the magnet. If you attach a powerful product to a thin surface, the field will pass right through and the holding will be smaller. To utilize full efficiency of this neodymium's potential, you require a sufficiently solid element of metal. The material oversaturation causes that on thin elements (e.g., car bodies), the product shows lower pull force. We suggest choosing the steel cross-section from these parameters.

Standard neodymium magnets lose parameters above the temperature limit. Avoid high temperatures – high temperature can permanently demagnetize this product. As the temperature rises, the neodymium's capacity briefly lowers. Do not use this product near heat sources exceeding its safe range. Exceeding the critical threshold will lead to destruction of magnetism.
*Important note: Heat tolerance is determined by both grade, but also on the magnet's shape. Flat magnets (low Pc) risk losing magnetic properties sooner compared to rod magnets. Warning indicator in the table signals a risk of irreversible loss for this specific geometry.

Two magnets interact from a wider radius than a neodymium and metal combination. The connection of two magnets produces a massive flux and a further horizon of performance. Planning to create a powerful holder? Utilize two neodymiums instead of a neodymium and a striker plate. Remember that when connecting a pair of magnets, the collision energy is extreme. The levitation is a bit weaker than the connection force, but still significant.
*Flux density between like poles drops to ~0 Gs in the exact middle between the magnets (due to field cancellation).
Important: Calculations apply to friction force of dual identical magnets (friction ~0.15 for Ni-Ni coating).

Powerful magnet radiation is a serious hazard to IT equipment and medical implants. These neodymiums produce a field that prevents correct functioning of digital equipment. Be aware: the invisible magnetic field passes through tissues and housings. Special caution must be taken by people with cochlear implants and insulin pumps. The risk also applies to: automatic timepieces, remotes, speakers, and displays. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

NdFeB products are very brittle – a strong collision with metal risks their cracking. Pay attention to connection velocity – a magnet released freely speeds with massive force. Impact energy can trigger coating fragments or painful pinches to skin. Hold the magnet firmly during mounting so it doesn't hit with great force against the steel surface. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Wear eye protection when playing with powerful specimens.

1. Wall mount (shear)

*Note: On a vertical wall, the magnet holds just a fraction of its perpendicular strength.

2. Steel thickness impact

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

3. Heat tolerance

*For N38 material, the max working temp is 80°C.

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.50

The chart above illustrates the magnetic characteristics of the material within the second quadrant of the hysteresis loop. 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 offered product is an exceptionally strong cylinder magnet, composed of durable NdFeB material, which, at dimensions of Ø50x20 mm, guarantees the highest energy density. The MW 50x20 / N38 component is characterized by an accuracy of ±0.1mm and industrial build quality, making it an excellent solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 70.10 kg), this product is in stock from our warehouse in Poland, ensuring quick order fulfillment. Moreover, its Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.
This model is perfect for building electric motors, advanced sensors, and efficient magnetic separators, where maximum induction on a small surface counts. Thanks to the high power of 687.66 N with a weight of only 294.52 g, this rod is indispensable in electronics 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 immediate cracking of this professional component. To ensure long-term durability in industry, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.
Magnets NdFeB grade N38 are strong enough for 90% of applications in modeling and machine building, where extreme miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø50x20), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.
This model is characterized by dimensions Ø50x20 mm, which, at a weight of 294.52 g, makes it an element with impressive magnetic energy density. The value of 687.66 N means that the magnet is capable of holding a weight many times exceeding its own mass of 294.52 g. The product has a [NiCuNi] coating, which protects the surface against external factors, giving it an aesthetic, silvery shine.
This rod magnet is magnetized axially (along the height of 20 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 diametrically if your project requires it.

Advantages and disadvantages of neodymium magnets.

Benefits

Apart from their strong magnetic energy, neodymium magnets have these key benefits:
  • Their magnetic field is maintained, and after approximately ten years it decreases only by ~1% (theoretically),
  • They are noted for resistance to demagnetization induced by external disturbances,
  • In other words, due to the aesthetic layer of silver, the element gains a professional look,
  • They feature high magnetic induction at the operating surface, which affects their effectiveness,
  • Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
  • In view of the ability of flexible forming and customization to custom needs, neodymium magnets can be manufactured in a variety of geometric configurations, which expands the range of possible applications,
  • Fundamental importance in modern industrial fields – they serve a role in magnetic memories, electric motors, precision medical tools, and modern systems.
  • Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,

Disadvantages

Drawbacks and weaknesses of neodymium magnets: weaknesses and usage proposals
  • At strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
  • Neodymium magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
  • They oxidize in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
  • We suggest casing - magnetic mount, due to difficulties in creating threads inside the magnet and complicated shapes.
  • Possible danger related to microscopic parts of magnets are risky, if swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small elements of these products can be problematic in diagnostics medical in case of swallowing.
  • Due to neodymium price, their price is higher than average,

Pull force analysis

Detachment force of the magnet in optimal conditions – what affects it?

The load parameter shown represents the peak performance, recorded under optimal environment, namely:
  • with the use of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
  • whose transverse dimension is min. 10 mm
  • characterized by smoothness
  • with total lack of distance (no paint)
  • under vertical force vector (90-degree angle)
  • in stable room temperature

Impact of factors on magnetic holding capacity in practice

Effective lifting capacity is influenced by specific conditions, such as (from most important):
  • Gap (betwixt the magnet and the plate), since even a microscopic distance (e.g. 0.5 mm) results in a drastic drop in force by up to 50% (this also applies to varnish, corrosion or dirt).
  • Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
  • Substrate thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
  • Plate material – low-carbon steel gives the best results. Higher carbon content reduce magnetic properties and lifting capacity.
  • Base smoothness – the more even the surface, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
  • Temperature influence – high temperature reduces pulling force. Too high temperature can permanently demagnetize the magnet.

Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under attempts to slide the magnet the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate reduces the lifting capacity.

Warnings
Caution required

Handle magnets with awareness. Their immense force can surprise even professionals. Be vigilant and do not underestimate their force.

Electronic hazard

Powerful magnetic fields can destroy records on credit cards, hard drives, and other magnetic media. Maintain a gap of min. 10 cm.

Shattering risk

Neodymium magnets are ceramic materials, meaning they are fragile like glass. Collision of two magnets leads to them shattering into small pieces.

No play value

These products are not toys. Accidental ingestion of a few magnets may result in them connecting inside the digestive tract, which constitutes a severe health hazard and necessitates immediate surgery.

Fire warning

Dust created during grinding of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.

Life threat

For implant holders: Powerful magnets affect electronics. Keep at least 30 cm distance or request help to work with the magnets.

Sensitization to coating

Studies show that nickel (standard magnet coating) is a common allergen. For allergy sufferers, refrain from direct skin contact or select encased magnets.

Bodily injuries

Large magnets can smash fingers instantly. Under no circumstances put your hand betwixt two strong magnets.

GPS and phone interference

A powerful magnetic field negatively affects the functioning of magnetometers in phones and GPS navigation. Keep magnets near a smartphone to prevent damaging the sensors.

Heat sensitivity

Do not overheat. Neodymium magnets are sensitive to temperature. If you need operation above 80°C, ask us about HT versions (H, SH, UH).
