1. Shear force

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

2. Steel thickness impact

*Thin metal sheet (e.g. 0.5mm PC case) drastically reduces the holding force.

3. Temperature resistance

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

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 1.55

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 a very strong cylinder magnet, composed of durable NdFeB material, which, with dimensions of Ø2x10 mm, guarantees optimal power. This specific item features an accuracy of ±0.1mm and professional build quality, making it an ideal solution for the most demanding engineers and designers. As a magnetic rod with significant force (approx. 0.07 kg), this product is available off-the-shelf from our European logistics center, ensuring lightning-fast order fulfillment. Furthermore, its Ni-Cu-Ni coating secures 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 0.70 N with a weight of only 0.24 g, this rod is indispensable in electronics and wherever low weight is crucial.
Since our magnets have a tolerance of ±0.1mm, the best method is to glue them into holes with a slightly larger diameter (e.g., 2.1 mm) using two-component epoxy glues. To ensure stability in automation, 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 industrial neodymium magnets, offering a great economic balance and operational stability. If you need even stronger magnets in the same volume (Ø2x10), 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 2 mm and height 10 mm. The value of 0.70 N means that the magnet is capable of holding a weight many times exceeding its own mass of 0.24 g. The product has a [NiCuNi] coating, which secures it 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 2 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 through the diameter if your project requires it.

Advantages and disadvantages of rare earth magnets.

Pros

Besides their durability, neodymium magnets are valued for these benefits:
  • Their strength is durable, and after around 10 years it drops only by ~1% (according to research),
  • Neodymium magnets prove to be extremely resistant to magnetic field loss caused by external interference,
  • By using a reflective layer of silver, the element acquires an aesthetic look,
  • The surface of neodymium magnets generates a strong magnetic field – this is one of their assets,
  • Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
  • Possibility of individual forming and adjusting to specific requirements,
  • Key role in advanced technology sectors – they serve a role in hard drives, brushless drives, medical devices, also multitasking production systems.
  • Compactness – despite small sizes they generate large force, making them ideal for precision applications

Cons

Characteristics of disadvantages of neodymium magnets: weaknesses and usage proposals
  • At strong impacts they can break, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
  • Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening 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
  • When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
  • We suggest casing - magnetic mechanism, due to difficulties in realizing threads inside the magnet and complicated forms.
  • Possible danger to health – tiny shards of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child safety. Furthermore, small components of these products are able to complicate diagnosis medical when they are in the body.
  • Due to complex production process, their price is relatively high,

Pull force analysis

Detachment force of the magnet in optimal conditionswhat contributes to it?

Holding force of 0.07 kg is a result of laboratory testing performed under the following configuration:
  • using a plate made of mild steel, functioning as a circuit closing element
  • with a cross-section no less than 10 mm
  • with an polished touching surface
  • under conditions of no distance (metal-to-metal)
  • during detachment in a direction vertical to the mounting surface
  • at temperature room level

Lifting capacity in practice – influencing factors

Please note that the magnet holding will differ subject to elements below, in order of importance:
  • Distance (between the magnet and the metal), since even a microscopic distance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
  • Loading method – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
  • Substrate thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
  • Metal type – different alloys reacts the same. Alloy additives worsen the interaction with the magnet.
  • Smoothness – ideal contact is obtained only on polished steel. Rough texture reduce the real contact area, reducing force.
  • Heat – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).

Lifting capacity was determined with the use of a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, 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 load capacity.

Safety rules for work with NdFeB magnets
Crushing force

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

Magnets are brittle

Despite the nickel coating, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may crumble into hazardous fragments.

Danger to the youngest

Absolutely store magnets out of reach of children. Ingestion danger is high, and the effects of magnets clamping inside the body are very dangerous.

Implant safety

Warning for patients: Powerful magnets affect electronics. Maintain minimum 30 cm distance or request help to handle the magnets.

Heat warning

Regular neodymium magnets (grade N) lose power when the temperature surpasses 80°C. This process is irreversible.

Dust explosion hazard

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

Handling guide

Be careful. Neodymium magnets attract from a distance and connect with massive power, often quicker than you can react.

Cards and drives

Avoid bringing magnets close to a purse, laptop, or TV. The magnetism can permanently damage these devices and wipe information from cards.

Precision electronics

A strong magnetic field interferes with the functioning of magnetometers in phones and navigation systems. Maintain magnets near a device to prevent damaging the sensors.

Metal Allergy

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

Important! More info about hazards in the article: Safety of working with magnets.
