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

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.22

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.

This product is an extremely powerful cylindrical magnet, composed of modern NdFeB material, which, with dimensions of Ø10x1.5 mm, guarantees optimal power. This specific item is characterized by an accuracy of ±0.1mm and professional build quality, making it an ideal solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 0.82 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring rapid order fulfillment. Furthermore, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.
This model is ideal for building generators, advanced Hall effect sensors, and efficient filters, where field concentration on a small surface counts. Thanks to the pull force of 8.01 N with a weight of only 0.88 g, this cylindrical magnet is indispensable in electronics and wherever low weight is crucial.
Since our magnets have a very precise dimensions, the best method is to glue them into holes with a slightly larger diameter (e.g., 10.1 mm) using epoxy glues. To ensure long-term durability 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.
Grade N38 is the most frequently chosen standard for industrial neodymium magnets, offering a great economic balance and operational stability. If you need the strongest magnets in the same volume (Ø10x1.5), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.
This model is characterized by dimensions Ø10x1.5 mm, which, at a weight of 0.88 g, makes it an element with high magnetic energy density. The key parameter here is the holding force amounting to approximately 0.82 kg (force ~8.01 N), which, with such defined dimensions, proves the high grade of the NdFeB material. The product has a [NiCuNi] coating, which secures it against oxidation, giving it an aesthetic, silvery shine.
This cylinder is magnetized axially (along the height of 1.5 mm), which means that the N and S poles are located on the flat, circular surfaces. Thanks to this, the magnet can be easily glued into a hole and achieve a strong field on the front surface. On request, we can also produce versions magnetized diametrically if your project requires it.

Advantages and disadvantages of rare earth magnets.

Pros

In addition to their magnetic capacity, neodymium magnets provide the following advantages:
  • They do not lose power, even during nearly ten years – the reduction in lifting capacity is only ~1% (theoretically),
  • Neodymium magnets are characterized by extremely resistant to magnetic field loss caused by external magnetic fields,
  • In other words, due to the smooth surface of nickel, the element is aesthetically pleasing,
  • They feature high magnetic induction at the operating surface, which improves attraction properties,
  • Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
  • Possibility of detailed forming as well as adapting to concrete conditions,
  • Key role in modern industrial fields – they are commonly used in data components, drive modules, precision medical tools, and multitasking production systems.
  • Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which makes them useful in miniature devices

Cons

Drawbacks and weaknesses of neodymium magnets: tips and applications.
  • They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also improves its resistance to damage
  • NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop 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 very resistant to heat
  • They rust in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
  • Limited ability of making nuts in the magnet and complicated shapes - recommended is a housing - magnetic holder.
  • Possible danger related to microscopic parts of magnets pose a threat, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, small elements of these products can complicate diagnosis medical in case of swallowing.
  • High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Holding force characteristics

Best holding force of the magnet in ideal parameterswhat contributes to it?

The declared magnet strength represents the maximum value, recorded under ideal test conditions, meaning:
  • on a base made of structural steel, effectively closing the magnetic field
  • with a thickness minimum 10 mm
  • with a plane cleaned and smooth
  • without the slightest insulating layer between the magnet and steel
  • under axial force vector (90-degree angle)
  • in neutral thermal conditions

Lifting capacity in practice – influencing factors

It is worth knowing that the working load will differ subject to elements below, starting with the most relevant:
  • Distance – existence of foreign body (paint, dirt, gap) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
  • Force direction – catalog parameter refers to pulling vertically. When slipping, the magnet exhibits much less (often approx. 20-30% of maximum force).
  • Substrate thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
  • Material composition – different alloys attracts identically. High carbon content weaken the attraction effect.
  • Plate texture – smooth surfaces ensure maximum contact, which increases field saturation. Rough surfaces weaken the grip.
  • Operating temperature – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and at low temperatures they can be stronger (up to a certain limit).

Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under parallel forces the holding force is lower. In addition, even a small distance between the magnet and the plate decreases the holding force.

Safe handling of NdFeB magnets
Fragile material

Protect your eyes. Magnets can fracture upon uncontrolled impact, ejecting shards into the air. We recommend safety glasses.

Physical harm

Mind your fingers. Two large magnets will join immediately with a force of massive weight, destroying anything in their path. Exercise extreme caution!

Caution required

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

Medical implants

Warning for patients: Powerful magnets affect medical devices. Keep minimum 30 cm distance or request help to work with the magnets.

Combustion hazard

Mechanical processing of neodymium magnets carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.

Adults only

NdFeB magnets are not intended for children. Accidental ingestion of several magnets can lead to them attracting across intestines, which constitutes a critical condition and necessitates urgent medical intervention.

Safe distance

Do not bring magnets near a wallet, laptop, or TV. The magnetism can permanently damage these devices and erase data from cards.

Thermal limits

Do not overheat. NdFeB magnets are sensitive to temperature. If you require operation above 80°C, inquire about special high-temperature series (H, SH, UH).

Avoid contact if allergic

Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If an allergic reaction occurs, immediately stop working with magnets and use protective gear.

Threat to navigation

Navigation devices and mobile phones are highly sensitive to magnetism. Close proximity with a powerful NdFeB magnet can permanently damage the sensors in your phone.
