1. Vertical hold

*Caution: On a vertical surface, the magnet holds only approx. 20-30% of its nominal pull.

2. Plate thickness effect

*Thin steel (e.g. computer case) significantly limits the holding force.

3. Heat tolerance

*For N38 material, the max working temp is 80°C.

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.66

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.

The presented product is a very strong rod magnet, produced from advanced NdFeB material, which, with dimensions of Ø10x6 mm, guarantees optimal power. The MW 10x6 / N38 model is characterized by high dimensional repeatability and professional build quality, making it an ideal solution for professional engineers and designers. As a magnetic rod with significant force (approx. 3.38 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring lightning-fast order fulfillment. Additionally, its Ni-Cu-Ni coating effectively protects it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.
It successfully proves itself in DIY projects, advanced robotics, and broadly understood industry, serving as a fastening or actuating element. Thanks to the high power of 33.12 N with a weight of only 3.53 g, this rod is indispensable in miniature devices and wherever low weight is crucial.
Due to the brittleness of the NdFeB material, we absolutely advise against force-fitting (so-called press-fit), as this risks chipping the coating of this professional component. To ensure long-term durability in automation, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.
Magnets N38 are strong enough for 90% of applications in modeling and machine building, where extreme miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø10x6), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.
This model is characterized by dimensions Ø10x6 mm, which, at a weight of 3.53 g, makes it an element with impressive magnetic energy density. The key parameter here is the holding force amounting to approximately 3.38 kg (force ~33.12 N), which, with such compact dimensions, proves the high grade of the NdFeB material. The product has a [NiCuNi] coating, which secures it against external factors, 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 10 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.

Strengths and weaknesses of neodymium magnets.

Strengths

In addition to their long-term stability, neodymium magnets provide the following advantages:
  • They do not lose power, even during approximately ten years – the reduction in strength is only ~1% (according to tests),
  • Neodymium magnets are highly resistant to loss of magnetic properties caused by external field sources,
  • The use of an aesthetic finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
  • Neodymium magnets deliver maximum magnetic induction on a small surface, which increases force concentration,
  • Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for functioning at temperatures reaching 230°C and above...
  • Considering the ability of free forming and customization to specialized solutions, neodymium magnets can be produced in a wide range of shapes and sizes, which makes them more universal,
  • Key role in modern industrial fields – they are utilized in mass storage devices, motor assemblies, medical equipment, as well as technologically advanced constructions.
  • Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which enables their usage in miniature devices

Weaknesses

Problematic aspects of neodymium magnets: application proposals
  • To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
  • We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
  • Magnets exposed to a humid environment can rust. Therefore while using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
  • We suggest casing - magnetic mechanism, due to difficulties in creating nuts inside the magnet and complicated forms.
  • Potential hazard resulting from small fragments of magnets are risky, when accidentally swallowed, which becomes key in the context of child health protection. Additionally, small elements of these products can complicate diagnosis medical when they are in the body.
  • With budget limitations the cost of neodymium magnets can be a barrier,

Lifting parameters

Maximum magnetic pulling forcewhat affects it?

The lifting capacity listed is a result of laboratory testing conducted under specific, ideal conditions:
  • on a plate made of structural steel, perfectly concentrating the magnetic field
  • with a thickness of at least 10 mm
  • characterized by smoothness
  • with direct contact (no coatings)
  • for force applied at a right angle (in the magnet axis)
  • in stable room temperature

Practical lifting capacity: influencing factors

In real-world applications, the real power depends on several key aspects, listed from the most important:
  • Gap between surfaces – every millimeter of distance (caused e.g. by veneer or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
  • Angle of force application – maximum parameter is obtained only during pulling at a 90° angle. The shear force of the magnet along the plate is typically 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).
  • Steel grade – ideal substrate is pure iron steel. Stainless steels may have worse magnetic properties.
  • Base smoothness – the more even the surface, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
  • Temperature – heating the magnet results in weakening of induction. It is worth remembering the thermal limit for a given model.

Lifting capacity testing was conducted on a smooth plate of suitable thickness, under perpendicular forces, in contrast under attempts to slide the magnet the holding force is lower. Additionally, even a slight gap between the magnet’s surface and the plate decreases the holding force.

Precautions when working with NdFeB magnets
Allergy Warning

Allergy Notice: The nickel-copper-nickel coating contains nickel. If skin irritation happens, cease working with magnets and wear gloves.

Powerful field

Use magnets consciously. Their immense force can shock even professionals. Be vigilant and respect their power.

Operating temperature

Do not overheat. Neodymium magnets are susceptible to temperature. If you require operation above 80°C, inquire about HT versions (H, SH, UH).

Fragile material

Watch out for shards. Magnets can fracture upon violent connection, launching sharp fragments into the air. Wear goggles.

Health Danger

Patients with a pacemaker should maintain an absolute distance from magnets. The magnetic field can stop the operation of the life-saving device.

Mechanical processing

Dust produced during grinding of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.

Adults only

Adult use only. Small elements pose a choking risk, causing serious injuries. Keep out of reach of children and animals.

Bone fractures

Pinching hazard: The attraction force is so great that it can result in blood blisters, crushing, and even bone fractures. Protective gloves are recommended.

GPS and phone interference

Remember: rare earth magnets produce a field that confuses precision electronics. Keep a safe distance from your mobile, tablet, and navigation systems.

Magnetic media

Data protection: Strong magnets can ruin payment cards and sensitive devices (heart implants, medical aids, timepieces).
