1. Vertical hold

*Note: On a vertical surface, the magnet holds only a fraction of its nominal pull.

2. Efficiency vs thickness

*Thin metal sheet (e.g. computer case) severely weakens the holding force.

3. Power loss vs temp

*For standard magnets, the critical limit is 80°C.

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.35

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 exceptionally strong cylinder magnet, composed of advanced NdFeB material, which, with dimensions of Ø24x6 mm, guarantees maximum efficiency. This specific item is characterized by an accuracy of ±0.1mm and industrial build quality, making it an excellent solution for professional engineers and designers. As a magnetic rod with significant force (approx. 9.98 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring quick order fulfillment. Furthermore, its Ni-Cu-Ni coating effectively protects it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.
It finds application in DIY projects, advanced robotics, and broadly understood industry, serving as a fastening or actuating element. Thanks to the high power of 97.88 N with a weight of only 20.36 g, this cylindrical magnet 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., 24.1 mm) using epoxy glues. To ensure stability in industry, specialized industrial adhesives 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 a great economic balance and high resistance to demagnetization. If you need even stronger magnets in the same volume (Ø24x6), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.
This model is characterized by dimensions Ø24x6 mm, which, at a weight of 20.36 g, makes it an element with high magnetic energy density. The value of 97.88 N means that the magnet is capable of holding a weight many times exceeding its own mass of 20.36 g. The product has a [NiCuNi] coating, which protects the surface against external factors, giving it an aesthetic, silvery shine.
This rod magnet is magnetized axially (along the height of 6 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 as well as disadvantages of Nd2Fe14B magnets.

Advantages

Besides their magnetic performance, neodymium magnets are valued for these benefits:
  • Their magnetic field remains stable, and after approximately 10 years it drops only by ~1% (theoretically),
  • They maintain their magnetic properties even under close interference source,
  • A magnet with a smooth nickel surface is more attractive,
  • They show high magnetic induction at the operating surface, which improves attraction properties,
  • 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 precise forming and optimizing to precise needs,
  • Significant place in advanced technology sectors – they are used in magnetic memories, motor assemblies, diagnostic systems, also modern systems.
  • Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Cons

Disadvantages of neodymium magnets:
  • At strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
  • We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
  • Magnets exposed to a humid environment can rust. Therefore while using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
  • Limited possibility of making nuts in the magnet and complicated shapes - recommended is cover - mounting mechanism.
  • Health risk related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child health protection. Furthermore, small components of these devices are able to complicate diagnosis medical in case of swallowing.
  • Due to neodymium price, their price is relatively high,

Holding force characteristics

Magnetic strength at its maximum – what it depends on?

Information about lifting capacity was determined for the most favorable conditions, including:
  • using a plate made of mild steel, serving as a magnetic yoke
  • with a cross-section no less than 10 mm
  • with a surface free of scratches
  • with total lack of distance (without paint)
  • for force acting at a right angle (in the magnet axis)
  • in stable room temperature

Determinants of practical lifting force of a magnet

It is worth knowing that the magnet holding will differ depending on the following factors, in order of importance:
  • Distance – the presence of foreign body (paint, tape, gap) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
  • Force direction – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet holds much less (often approx. 20-30% of nominal force).
  • Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of generating force.
  • Plate material – low-carbon steel gives the best results. Higher carbon content reduce magnetic properties and holding force.
  • Smoothness – full contact is possible only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
  • Thermal conditions – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).

Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate decreases the holding force.

Safety rules for work with NdFeB magnets
Serious injuries

Risk of injury: The attraction force is so great that it can result in blood blisters, pinching, and even bone fractures. Protective gloves are recommended.

Heat warning

Keep cool. NdFeB magnets are sensitive to temperature. If you need resistance above 80°C, look for HT versions (H, SH, UH).

Safe operation

Before starting, read the rules. Sudden snapping can break the magnet or injure your hand. Be predictive.

Danger to the youngest

Product intended for adults. Tiny parts pose a choking risk, causing intestinal necrosis. Keep out of reach of kids and pets.

Magnetic interference

Navigation devices and smartphones are highly susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can ruin the internal compass in your phone.

Fragile material

Watch out for shards. Magnets can explode upon uncontrolled impact, ejecting shards into the air. Eye protection is mandatory.

Data carriers

Do not bring magnets near a wallet, laptop, or screen. The magnetism can irreversibly ruin these devices and wipe information from cards.

Machining danger

Drilling and cutting of NdFeB material poses a fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.

Warning for allergy sufferers

It is widely known that nickel (the usual finish) is a strong allergen. For allergy sufferers, refrain from touching magnets with bare hands or select coated magnets.

Pacemakers

Health Alert: Neodymium magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.
