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 significantly with every subsequent millimeter of distance. Keep in mind that even a very thin break (e.g., dirt, varnish, rust) noticeably weakens the grip. Magnets operate most effectively at the point of direct contact; gap drastically cuts the power. Observe how quickly the parameters fall, when the magnet does not adhere directly to the metal substrate. When planning the assembly, discard redundant distances.

The following data defines the approximate weight limit necessary to initiate the slippage of the magnet down against a vertical steel wall (considering typical friction). This parameter is a function of the air gap between the magnet and the metal.

When hanging a holder on a vertical surface (e.g., a car body), it will maintain only approx. 20%-30% of its maximum pull force. Gravity and a weak degree of grip influence the fact that holders slip easier than they pop off the substrate. Want to create a wall mount? Consider that the sliding force is much weaker than the maximum static pull force. On a smooth steel, the holder will give way down under a significantly smaller cargo. Application of an anti-slip coating can drastically increase the grip.

A thin sheet cannot take in the full magnetic flux, which squanders power of the magnet. Should you mount a strong magnet to a too thin substrate, the field will pass right through and the holding will be smaller. To squeeze full efficiency of this neodymium's power, you require a sufficiently solid backing of steel. The saturation phenomenon causes that on delicate walls (e.g., thin profiles), the product shows lower pull force. We suggest choosing the steel cross-section based on the following data.

Standard neodymium magnets change their properties parameters past the thermal threshold. Protect against heat – excessive heat can permanently demagnetize this magnet. As the temperature rises, the neodymium's power temporarily drops. Avoid using this magnet in hot environments higher than its operating temperature limit. Too high temperature will result in permanent loss of magnetic properties.
*Engineering note: Thermal stability depends not only on the material grade, but also on the magnet's shape. Thin magnets (pancake types) may lose charge permanently at lower temperatures than long magnets. Warning indicator in the table signals a risk of irreversible loss for this particular item.

Two strong neodymiums attract each other from a wider radius than a neodymium and metal combination. Such a system of magnet-to-magnet generates a stronger field and a larger range of action. Want to build a solid fastener? Apply two magnets instead of one magnet and a striker plate. Be careful that when attracting two neodymiums, the pinch force is huge. The levitation is slightly lower than the attraction, but still impressive.
*Flux density between like poles drops to ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
Note: Figures refer to friction force of two matching neodymium magnets (friction ~0.15 for Ni-Ni layer).

Extremely neodym field is a serious hazard to electronics as well as pacemakers. These neodymiums produce a flux that destroys function of digital equipment. Remember: the invisible magnetic field penetrates the body and glass. Exceptional care must be exercised by people with hearing aids 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 precise measuring instruments.

Magnetic elements are very brittle – a violent impact against metal causes immediate chipping. Control the attraction moment – a magnet released freely speeds with massive force. Striking energy can cause material chips or dangerous crushing to fingers. Always hold the magnet during bringing near metal so it doesn't hit violently against the steel surface. A collision at high speed almost guarantees destruction of the magnet. Use safety goggles when working with large magnets.

*Caution: On a vertical surface, the magnet retains only ~20% of its max power.

2. Efficiency vs thickness

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

3. Thermal stability

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

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

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

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 rod magnet, made from advanced NdFeB material, which, with dimensions of Ø3x1 mm, guarantees maximum efficiency. This specific item features an accuracy of ±0.1mm and industrial build quality, making it a perfect solution for the most demanding engineers and designers. As a cylindrical magnet with significant force (approx. 0.21 kg), this product is available off-the-shelf from our European logistics center, ensuring lightning-fast order fulfillment. Additionally, its Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.
It finds application in modeling, advanced automation, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 2.10 N with a weight of only 0.05 g, this cylindrical magnet is indispensable in electronics and wherever every gram matters.
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 industry, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.
Magnets NdFeB grade N38 are suitable for the majority 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 (Ø3x1), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.
The presented product is a neodymium magnet with precisely defined parameters: diameter 3 mm and height 1 mm. The key parameter here is the lifting capacity amounting to approximately 0.21 kg (force ~2.10 N), which, with such compact dimensions, proves the high power of the NdFeB material. The product has a [NiCuNi] coating, which secures it against external factors, 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 3 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 diametrically if your project requires it.

Advantages as well as disadvantages of rare earth magnets.

Advantages

Apart from their notable power, neodymium magnets have these key benefits:
  • They have stable power, and over more than ten years their performance decreases symbolically – ~1% (according to theory),
  • They retain their magnetic properties even under strong external field,
  • The use of an elegant coating of noble metals (nickel, gold, silver) causes the element to have aesthetics,
  • Neodymium magnets generate maximum magnetic induction on a contact point, which ensures high operational effectiveness,
  • Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
  • Possibility of exact creating and modifying to concrete conditions,
  • Huge importance in future technologies – they are commonly used in hard drives, brushless drives, medical equipment, as well as other advanced devices.
  • Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,

Disadvantages

Disadvantages of neodymium magnets:
  • At very strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
  • Neodymium magnets lose strength 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
  • When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
  • Due to limitations in creating threads and complex shapes in magnets, we propose using casing - magnetic holder.
  • Possible danger resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child health protection. It is also worth noting that small components of these products are able to complicate diagnosis medical after entering the body.
  • Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Lifting parameters

Maximum holding power of the magnet – what affects it?

The specified lifting capacity refers to the peak performance, measured under laboratory conditions, meaning:
  • using a plate made of mild steel, acting as a magnetic yoke
  • possessing a massiveness of at least 10 mm to avoid saturation
  • characterized by lack of roughness
  • under conditions of ideal adhesion (metal-to-metal)
  • under axial force direction (90-degree angle)
  • at conditions approx. 20°C

Magnet lifting force in use – key factors

Real force impacted by specific conditions, mainly (from most important):
  • Space between magnet and steel – every millimeter of separation (caused e.g. by veneer or dirt) diminishes the pulling force, often by half at just 0.5 mm.
  • Direction of force – maximum parameter is obtained only during perpendicular pulling. The shear force of the magnet along the plate is standardly several times smaller (approx. 1/5 of the lifting capacity).
  • Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
  • Steel type – low-carbon steel attracts best. Higher carbon content lower magnetic permeability and holding force.
  • Plate texture – smooth surfaces guarantee perfect abutment, which increases field saturation. Rough surfaces weaken the grip.
  • Thermal environment – temperature increase causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity was measured using a steel plate with a smooth surface of suitable thickness (min. 20 mm), under vertically applied force, however under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Moreover, even a minimal clearance between the magnet’s surface and the plate lowers the holding force.

Medical facts indicate that the nickel plating (the usual finish) is a common allergen. If your skin reacts to metals, prevent touching magnets with bare hands or choose versions in plastic housing.

Fragile material

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

Precision electronics

A strong magnetic field disrupts the functioning of magnetometers in smartphones and navigation systems. Do not bring magnets close to a smartphone to avoid damaging the sensors.

Crushing force

Big blocks can break fingers instantly. Never put your hand between two attracting surfaces.

Heat sensitivity

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

Dust explosion hazard

Powder created during grinding of magnets is combustible. Avoid drilling into magnets unless you are an expert.

Product not for children

These products are not intended for children. Accidental ingestion of multiple magnets may result in them connecting inside the digestive tract, which constitutes a critical condition and necessitates urgent medical intervention.

Respect the power

Before starting, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.

Keep away from computers

Powerful magnetic fields can erase data on payment cards, HDDs, and other magnetic media. Keep a distance of at least 10 cm.

Pacemakers

Individuals with a ICD must maintain an large gap from magnets. The magnetism can disrupt the operation of the implant.
