1. Vertical hold

*Caution: On a vertical surface, the magnet retains only ~20% of its nominal pull.

2. Plate thickness effect

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

3. Thermal stability

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

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.89

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.

Field Strength

Other offers

The offered product is an incredibly powerful rod magnet, composed of modern NdFeB material, which, at dimensions of Ø6x6 mm, guarantees the highest energy density. This specific item boasts high dimensional repeatability and professional build quality, making it an ideal solution for the most demanding engineers and designers. As a magnetic rod with significant force (approx. 1.14 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring quick order fulfillment. Additionally, its Ni-Cu-Ni coating effectively protects it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.
This model is created for building generators, advanced sensors, and efficient magnetic separators, where field concentration on a small surface counts. Thanks to the pull force of 11.18 N with a weight of only 1.27 g, this cylindrical magnet is indispensable in electronics and wherever every gram matters.
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, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.
Grade N38 is the most frequently chosen standard for professional neodymium magnets, offering an optimal price-to-power ratio and operational stability. If you need even stronger magnets in the same volume (Ø6x6), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.
This model is characterized by dimensions Ø6x6 mm, which, at a weight of 1.27 g, makes it an element with high magnetic energy density. The key parameter here is the holding force amounting to approximately 1.14 kg (force ~11.18 N), which, with such compact dimensions, proves the high power 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 6 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 through the diameter if your project requires it.

Strengths and weaknesses of Nd2Fe14B magnets.

Strengths

Besides their tremendous strength, neodymium magnets offer the following advantages:
  • They retain full power for around 10 years – the drop is just ~1% (in theory),
  • They possess excellent resistance to magnetic field loss due to opposing magnetic fields,
  • Thanks to the glossy finish, the surface of Ni-Cu-Ni, gold-plated, or silver-plated gives an visually attractive appearance,
  • Neodymium magnets deliver maximum magnetic induction on a small surface, which increases force concentration,
  • Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
  • Thanks to flexibility in constructing and the capacity to adapt to unusual requirements,
  • Key role in high-tech industry – they find application in data components, electromotive mechanisms, medical devices, and industrial machines.
  • Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Limitations

Disadvantages of NdFeB magnets:
  • Brittleness is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a steel housing, which not only secures them against impacts but also increases their durability
  • When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
  • Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
  • Due to limitations in realizing threads and complicated shapes in magnets, we propose using cover - magnetic mount.
  • Health risk to health – tiny shards of magnets are risky, if swallowed, which becomes key in the context of child safety. It is also worth noting that small components of these magnets can complicate diagnosis medical when they are in the body.
  • Due to neodymium price, their price is higher than average,

Holding force characteristics

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

Holding force of 1.14 kg is a theoretical maximum value performed under the following configuration:
  • on a base made of mild steel, effectively closing the magnetic flux
  • possessing a thickness of minimum 10 mm to avoid saturation
  • characterized by lack of roughness
  • under conditions of ideal adhesion (surface-to-surface)
  • under vertical application of breakaway force (90-degree angle)
  • at conditions approx. 20°C

Impact of factors on magnetic holding capacity in practice

It is worth knowing that the magnet holding will differ influenced by the following factors, in order of importance:
  • Gap between surfaces – every millimeter of separation (caused e.g. by varnish or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
  • Loading method – catalog parameter refers to detachment vertically. When attempting to slide, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
  • Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
  • Plate material – mild steel attracts best. Alloy steels reduce magnetic properties and holding force.
  • Surface condition – smooth surfaces guarantee perfect abutment, which increases force. Uneven metal weaken the grip.
  • Temperature influence – hot environment weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.

Lifting capacity testing was carried out on a smooth plate of suitable thickness, under perpendicular forces, however under shearing force the load capacity is reduced by as much as 75%. Additionally, even a minimal clearance between the magnet’s surface and the plate decreases the holding force.

Warnings
Thermal limits

Avoid heat. NdFeB magnets are sensitive to heat. If you need operation above 80°C, inquire about special high-temperature series (H, SH, UH).

Bone fractures

Mind your fingers. Two large magnets will snap together instantly with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!

Respect the power

Before starting, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.

Protect data

Avoid bringing magnets close to a purse, computer, or TV. The magnetism can irreversibly ruin these devices and erase data from cards.

Material brittleness

NdFeB magnets are sintered ceramics, which means they are very brittle. Collision of two magnets will cause them cracking into shards.

Danger to pacemakers

For implant holders: Strong magnetic fields affect electronics. Maintain at least 30 cm distance or ask another person to work with the magnets.

GPS Danger

A powerful magnetic field interferes with the functioning of compasses in phones and GPS navigation. Keep magnets near a device to prevent damaging the sensors.

Warning for allergy sufferers

Certain individuals have a sensitization to Ni, which is the typical protective layer for NdFeB magnets. Frequent touching can result in a rash. We suggest wear protective gloves.

Do not drill into magnets

Dust generated during grinding of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.

Danger to the youngest

These products are not suitable for play. Swallowing a few magnets can lead to them pinching intestinal walls, which constitutes a severe health hazard and necessitates immediate surgery.
