1. Wall mount (shear)

*Note: On a vertical wall, the magnet holds only approx. 20-30% of its max power.

2. Steel saturation

*Thin steel (e.g. computer case) drastically reduces the holding force.

3. Heat tolerance

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

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 1.21

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.

Field Strength

Other products

This product is a very strong cylindrical magnet, produced from modern NdFeB material, which, with dimensions of Ø5x10 mm, guarantees optimal power. The MW 5x10 / N38 component is characterized by high dimensional repeatability and professional build quality, making it an ideal solution for the most demanding engineers and designers. As a magnetic rod with impressive force (approx. 0.56 kg), this product is in stock from our European logistics center, ensuring quick order fulfillment. Additionally, its Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.
This model is perfect for building generators, advanced Hall effect sensors, and efficient magnetic separators, where field concentration on a small surface counts. Thanks to the high power of 5.45 N with a weight of only 1.47 g, this rod is indispensable in electronics and wherever low weight is crucial.
Since our magnets have a tolerance of ±0.1mm, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 5.1 mm) using two-component epoxy glues. To ensure stability in industry, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.
Grade N38 is the most popular 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 (Ø5x10), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.
The presented product is a neodymium magnet with precisely defined parameters: diameter 5 mm and height 10 mm. The key parameter here is the holding force amounting to approximately 0.56 kg (force ~5.45 N), which, with such defined dimensions, proves the high power of the NdFeB material. 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 5 mm. 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.

Pros and cons of neodymium magnets.

Advantages

Apart from their superior magnetic energy, neodymium magnets have these key benefits:
  • They do not lose power, even during approximately 10 years – the decrease in power is only ~1% (according to tests),
  • Magnets very well defend themselves against loss of magnetization caused by foreign field sources,
  • A magnet with a shiny silver surface has an effective appearance,
  • Neodymium magnets generate maximum magnetic induction on a small surface, which ensures high operational effectiveness,
  • Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
  • Thanks to flexibility in designing and the capacity to adapt to client solutions,
  • Huge importance in modern industrial fields – they are commonly used in mass storage devices, motor assemblies, advanced medical instruments, and complex engineering applications.
  • Compactness – despite small sizes they generate large force, making them ideal for precision applications

Weaknesses

Problematic aspects of neodymium magnets and proposals for their use:
  • To avoid cracks under impact, we recommend using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
  • We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
  • They rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
  • Limited possibility of producing threads in the magnet and complicated shapes - preferred is casing - mounting mechanism.
  • Possible danger to health – tiny shards of magnets pose a threat, if swallowed, which becomes key in the context of child safety. Furthermore, small components of these products are able to complicate diagnosis medical when they are in the body.
  • Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Holding force characteristics

Maximum lifting force for a neodymium magnet – what contributes to it?

The specified lifting capacity concerns the peak performance, recorded under ideal test conditions, specifically:
  • using a base made of low-carbon steel, acting as a magnetic yoke
  • possessing a thickness of minimum 10 mm to avoid saturation
  • with a surface perfectly flat
  • under conditions of gap-free contact (surface-to-surface)
  • under perpendicular application of breakaway force (90-degree angle)
  • in temp. approx. 20°C

Lifting capacity in real conditions – factors

In practice, the real power results from a number of factors, listed from crucial:
  • Distance – the presence of foreign body (rust, dirt, air) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
  • Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the nominal value.
  • Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet restricts the attraction force (the magnet "punches through" it).
  • Material composition – not every steel reacts the same. High carbon content weaken the attraction effect.
  • Surface finish – ideal contact is possible only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
  • Thermal environment – heating the magnet results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.

Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Moreover, even a slight gap between the magnet and the plate decreases the lifting capacity.

Safety rules for work with NdFeB magnets
Respect the power

Handle magnets with awareness. Their powerful strength can shock even experienced users. Stay alert and respect their power.

Nickel allergy

Allergy Notice: The nickel-copper-nickel coating consists of nickel. If redness happens, immediately stop working with magnets and wear gloves.

Keep away from computers

Data protection: Strong magnets can ruin data carriers and sensitive devices (heart implants, hearing aids, mechanical watches).

Operating temperature

Watch the temperature. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and strength.

Dust is flammable

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

GPS and phone interference

Be aware: neodymium magnets produce a field that interferes with sensitive sensors. Maintain a safe distance from your phone, device, and GPS.

Beware of splinters

Watch out for shards. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. Wear goggles.

Swallowing risk

Product intended for adults. Tiny parts can be swallowed, leading to serious injuries. Store out of reach of kids and pets.

Crushing risk

Big blocks can break fingers in a fraction of a second. Under no circumstances put your hand betwixt two attracting surfaces.

Warning for heart patients

Warning for patients: Strong magnetic fields affect medical devices. Keep at least 30 cm distance or request help to handle the magnets.
