1. Shear force

*Caution: On a vertical surface, the magnet holds just approx. 20-30% of its perpendicular strength.

2. Plate thickness effect

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

3. Thermal stability

*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) = 1.55

This simulation demonstrates the magnetic stability of the selected magnet under specific geometric conditions. 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 incredibly powerful rod magnet, produced from modern NdFeB material, which, at dimensions of Ø2x10 mm, guarantees the highest energy density. This specific item features an accuracy of ±0.1mm and industrial build quality, making it an ideal solution for the most demanding engineers and designers. As a cylindrical magnet with impressive force (approx. 0.07 kg), this product is in stock from our European logistics center, ensuring lightning-fast order fulfillment. Furthermore, its Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.
It successfully proves itself in modeling, advanced automation, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 0.70 N with a weight of only 0.24 g, this cylindrical magnet 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 precision component. To ensure stability in automation, anaerobic resins 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 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 available off-the-shelf in our store.
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 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 as well as weaknesses of neodymium magnets.

Benefits

Apart from their superior magnetic energy, neodymium magnets have these key benefits:
  • Their magnetic field is durable, and after around ten years it drops only by ~1% (according to research),
  • They feature excellent resistance to magnetism drop as a result of opposing magnetic fields,
  • Thanks to the reflective finish, the coating of Ni-Cu-Ni, gold-plated, or silver-plated gives an modern appearance,
  • Magnetic induction on the top side of the magnet remains very high,
  • Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
  • Thanks to flexibility in constructing and the capacity to modify to unusual requirements,
  • Fundamental importance in advanced technology sectors – they are commonly used in computer drives, brushless drives, precision medical tools, and complex engineering applications.
  • Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,

Disadvantages

Characteristics of disadvantages of neodymium magnets: application proposals
  • Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a strong case, which not only secures them against impacts but also increases their durability
  • When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
  • They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
  • Limited possibility of making threads in the magnet and complicated shapes - recommended is casing - magnet mounting.
  • Potential hazard resulting from small fragments of magnets pose a threat, if swallowed, which is particularly important in the context of child health protection. Furthermore, small components of these products can be problematic in diagnostics medical when they are in the body.
  • With large orders the cost of neodymium magnets can be a barrier,

Pull force analysis

Maximum lifting capacity of the magnetwhat contributes to it?

Holding force of 0.07 kg is a result of laboratory testing performed under specific, ideal conditions:
  • using a base made of mild steel, functioning as a circuit closing element
  • whose transverse dimension is min. 10 mm
  • with an ground touching surface
  • under conditions of no distance (metal-to-metal)
  • during detachment in a direction perpendicular to the mounting surface
  • at conditions approx. 20°C

What influences lifting capacity in practice

Bear in mind that the working load may be lower influenced by the following factors, in order of importance:
  • Air gap (between the magnet and the plate), as even a microscopic distance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to paint, corrosion or debris).
  • Load vector – maximum parameter is obtained only during pulling at a 90° angle. The shear force of the magnet along the surface is typically several times smaller (approx. 1/5 of the lifting capacity).
  • Base massiveness – insufficiently thick plate causes magnetic saturation, causing part of the flux to be lost into the air.
  • Material composition – different alloys reacts the same. High carbon content worsen the interaction with the magnet.
  • Plate texture – ground elements guarantee perfect abutment, which increases field saturation. Uneven metal reduce efficiency.
  • Heat – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).

Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet and the plate reduces the lifting capacity.

H&S for magnets
Medical interference

Patients with a pacemaker must keep an absolute distance from magnets. The magnetism can interfere with the functioning of the implant.

Electronic devices

Powerful magnetic fields can destroy records on credit cards, HDDs, and other magnetic media. Maintain a gap of at least 10 cm.

Bone fractures

Pinching hazard: The pulling power is so great that it can result in hematomas, pinching, and broken bones. Protective gloves are recommended.

Eye protection

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

GPS Danger

Remember: rare earth magnets generate a field that interferes with precision electronics. Maintain a separation from your mobile, tablet, and navigation systems.

Swallowing risk

NdFeB magnets are not intended for children. Swallowing a few magnets may result in them pinching intestinal walls, which poses a direct threat to life and necessitates immediate surgery.

Nickel coating and allergies

It is widely known that nickel (standard magnet coating) is a potent allergen. If your skin reacts to metals, avoid direct skin contact and choose encased magnets.

Do not underestimate power

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

Fire risk

Combustion risk: Neodymium dust is highly flammable. Do not process magnets without safety gear as this risks ignition.

Heat warning

Standard neodymium magnets (grade N) undergo demagnetization when the temperature goes above 80°C. Damage is permanent.
