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.

1. Vertical hold

*Note: On a vertical wall, the magnet retains just a fraction of its nominal pull.

2. Steel thickness impact

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

3. Heat tolerance

*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) = 0.74

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.

Other deals

This product is an incredibly powerful cylindrical magnet, composed of advanced NdFeB material, which, at dimensions of Ø14x10 mm, guarantees optimal power. The MW 14x10 / N38 model is characterized by a tolerance of ±0.1mm and professional build quality, making it an excellent solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 6.71 kg), this product is in stock from our European logistics center, ensuring quick order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.
This model is ideal for building electric motors, advanced Hall effect sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the pull force of 65.83 N with a weight of only 11.55 g, this rod is indispensable in electronics and wherever low weight is crucial.
Due to the delicate structure of the ceramic sinter, you must not use force-fitting (so-called press-fit), as this risks immediate cracking of this professional component. To ensure stability in automation, 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 professional neodymium magnets, offering an optimal price-to-power ratio and high resistance to demagnetization. If you need the strongest magnets in the same volume (Ø14x10), 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 Ø14x10 mm, which, at a weight of 11.55 g, makes it an element with high magnetic energy density. The value of 65.83 N means that the magnet is capable of holding a weight many times exceeding its own mass of 11.55 g. The product has a [NiCuNi] coating, which protects the surface against external factors, giving it an aesthetic, silvery shine.
This cylinder is magnetized axially (along the height of 10 mm), which means that the N and S poles are located on the flat, circular surfaces. Such an arrangement is most desirable 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.

Strengths and weaknesses of neodymium magnets.

Advantages

Besides their durability, neodymium magnets are valued for these benefits:
  • They have constant strength, and over nearly ten years their attraction force decreases symbolically – ~1% (in testing),
  • Magnets effectively protect themselves against loss of magnetization caused by ambient magnetic noise,
  • The use of an shiny coating of noble metals (nickel, gold, silver) causes the element to have aesthetics,
  • The surface of neodymium magnets generates a concentrated magnetic field – this is one of their assets,
  • Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
  • Possibility of precise creating as well as adjusting to specific applications,
  • Huge importance in modern industrial fields – they serve a role in mass storage devices, electromotive mechanisms, precision medical tools, also other advanced devices.
  • Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Disadvantages

Problematic aspects of neodymium magnets and proposals for their use:
  • Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a strong case, which not only protects them against impacts but also increases their durability
  • Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
  • Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
  • Due to limitations in creating threads and complex shapes in magnets, we propose using cover - magnetic holder.
  • Health risk related to microscopic parts of magnets pose a threat, in case of ingestion, which gains importance in the context of child health protection. Additionally, tiny parts of these devices can disrupt the diagnostic process medical after entering the body.
  • High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Holding force characteristics

Breakaway strength of the magnet in ideal conditionswhat contributes to it?

The lifting capacity listed is a theoretical maximum value executed under the following configuration:
  • using a base made of low-carbon steel, functioning as a circuit closing element
  • with a cross-section no less than 10 mm
  • with a surface free of scratches
  • without the slightest clearance between the magnet and steel
  • for force applied at a right angle (in the magnet axis)
  • at temperature approx. 20 degrees Celsius

Determinants of practical lifting force of a magnet

In real-world applications, the actual lifting capacity results from a number of factors, ranked from crucial:
  • Distance – existence of any layer (paint, tape, air) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
  • Load vector – highest force is reached only during perpendicular pulling. The shear force of the magnet along the surface is standardly several times lower (approx. 1/5 of the lifting capacity).
  • Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
  • Metal type – not every steel reacts the same. High carbon content weaken the attraction effect.
  • Surface condition – ground elements ensure maximum contact, which increases force. Uneven metal weaken the grip.
  • Temperature influence – hot environment weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity was assessed with the use of a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, whereas under parallel forces the holding force is lower. Moreover, even a slight gap between the magnet’s surface and the plate decreases the holding force.

Safe handling of NdFeB magnets
Safe distance

Intense magnetic fields can erase data on payment cards, hard drives, and other magnetic media. Stay away of min. 10 cm.

Beware of splinters

Despite metallic appearance, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.

Fire warning

Drilling and cutting of NdFeB material carries a risk of fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.

GPS and phone interference

A strong magnetic field negatively affects the functioning of compasses in phones and navigation systems. Do not bring magnets close to a device to avoid breaking the sensors.

Sensitization to coating

Nickel alert: The Ni-Cu-Ni coating consists of nickel. If skin irritation appears, cease working with magnets and wear gloves.

Adults only

These products are not intended for children. Swallowing a few magnets can lead to them connecting inside the digestive tract, which constitutes a severe health hazard and necessitates urgent medical intervention.

Immense force

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

Operating temperature

Watch the temperature. Heating the magnet to high heat will ruin its properties and strength.

Serious injuries

Mind your fingers. Two large magnets will join immediately with a force of massive weight, crushing anything in their path. Be careful!

Medical implants

Health Alert: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.

Caution! Details about hazards in the article: Magnet Safety Guide.
