1. Vertical hold

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

2. Steel thickness impact

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

3. Power loss vs temp

*For standard magnets, the max working temp is 80°C.

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.31

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.

Pulling force

Field Strength

Other proposals

This product is a very strong rod magnet, composed of durable NdFeB material, which, at dimensions of Ø14x3 mm, guarantees maximum efficiency. The MW 14x3 / N38 model is characterized by an accuracy of ±0.1mm and professional build quality, making it an excellent solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 2.76 kg), this product is in stock from our European logistics center, ensuring rapid 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 finds application in modeling, advanced robotics, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 27.06 N with a weight of only 3.46 g, this rod is indispensable in electronics and wherever low weight is crucial.
Since our magnets have a tolerance of ±0.1mm, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 14.1 mm) using epoxy glues. To ensure stability in automation, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.
Magnets NdFeB grade N38 are suitable for 90% of applications in modeling and machine building, where excessive miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø14x3), 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 14 mm and height 3 mm. The key parameter here is the holding force amounting to approximately 2.76 kg (force ~27.06 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.
This rod magnet is magnetized axially (along the height of 3 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 through the diameter if your project requires it.

Advantages as well as disadvantages of Nd2Fe14B magnets.

Advantages

In addition to their magnetic capacity, neodymium magnets provide the following advantages:
  • They do not lose power, even during nearly 10 years – the reduction in power is only ~1% (based on measurements),
  • They retain their magnetic properties even under strong external field,
  • By using a reflective layer of silver, the element presents an proper look,
  • Neodymium magnets generate maximum magnetic induction on a contact point, which increases force concentration,
  • Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
  • Possibility of detailed shaping and optimizing to specific needs,
  • Universal use in innovative solutions – they are used in computer drives, drive modules, medical devices, also complex engineering applications.
  • Compactness – despite small sizes they generate large force, making them ideal for precision applications

Cons

Disadvantages of neodymium magnets:
  • Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a steel housing, which not only protects them against impacts but also increases their durability
  • When exposed to high temperature, neodymium magnets experience a drop in force. 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
  • Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
  • Limited possibility of producing threads in the magnet and complicated forms - preferred is a housing - magnet mounting.
  • Health risk to health – tiny shards of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that small components of these devices are able to complicate diagnosis medical after entering the body.
  • Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Holding force characteristics

Maximum magnetic pulling forcewhat it depends on?

Breakaway force was determined for the most favorable conditions, including:
  • with the contact of a yoke made of low-carbon steel, ensuring full magnetic saturation
  • with a cross-section minimum 10 mm
  • characterized by smoothness
  • without any clearance between the magnet and steel
  • for force acting at a right angle (pull-off, not shear)
  • in neutral thermal conditions

Lifting capacity in real conditions – factors

Please note that the magnet holding may be lower subject to the following factors, starting with the most relevant:
  • Gap between surfaces – every millimeter of distance (caused e.g. by veneer or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
  • Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the nominal value.
  • Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
  • Material type – ideal substrate is pure iron steel. Stainless steels may generate lower lifting capacity.
  • Surface condition – smooth surfaces ensure maximum contact, which increases force. Uneven metal reduce efficiency.
  • Temperature – heating the magnet causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity was assessed by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under shearing force the load capacity is reduced by as much as 75%. In addition, even a minimal clearance between the magnet and the plate lowers the holding force.

Safe handling of neodymium magnets
Medical implants

People with a heart stimulator should maintain an safe separation from magnets. The magnetic field can stop the operation of the life-saving device.

Conscious usage

Use magnets with awareness. Their huge power can shock even professionals. Plan your moves and do not underestimate their power.

Do not overheat magnets

Regular neodymium magnets (N-type) lose magnetization when the temperature exceeds 80°C. This process is irreversible.

Adults only

Strictly keep magnets away from children. Ingestion danger is significant, and the effects of magnets connecting inside the body are fatal.

Bodily injuries

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

Shattering risk

Beware of splinters. Magnets can explode upon violent connection, launching shards into the air. We recommend safety glasses.

Dust explosion hazard

Machining of NdFeB material carries a risk of fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.

Safe distance

Data protection: Strong magnets can ruin data carriers and sensitive devices (heart implants, hearing aids, timepieces).

Magnetic interference

GPS units and smartphones are highly susceptible to magnetic fields. Close proximity with a strong magnet can permanently damage the sensors in your phone.

Metal Allergy

Medical facts indicate that nickel (standard magnet coating) is a common allergen. If your skin reacts to metals, avoid direct skin contact or choose encased magnets.
