Frequently asked questions

What is the maximum working temperature of a disc magnet?
Standard N-series grades work up to 80 °C. Grades N50, N52 and N54 have a lower limit of 60 °C, because coercivity falls as BHmax rises. Higher temperatures require the H (120 °C), SH (150 °C), UH (180 °C), EH (200 °C) or AH (230 °C) series. Within the working range the magnet loses about 0.11% of its induction per degree, and that loss is reversible.
What is the difference between N38, N42 and N52?
The number after N is the energy product BHmax. Moving from N38 to N52 raises it by several tens of percent, but the real holding force increases by roughly 20%, because force also depends on geometry and on the magnetic circuit. N52 costs about twice as much as N42, so for most mounting work N38–N42 is the best price-to-force ratio.
What is the dimensional tolerance?
±0.1 mm as standard, ±0.05 mm to order. The tolerance is stated next to the dimensions on every product page.

Pulling power drops sharply with every subsequent millimeter of spacing. Note that every additional insulation layer (e.g., contamination, paint, veneer) noticeably diminishes the holding power. Magnetic products operate optimally in perfect adhesion; air break nullifies the power. Analyze how quickly the load capacity plummet, when the magnet does not touch flatly to the steel surface. When designing the mounting, discard additional spacers.

The following data indicates the theoretical shear load needed to start the slippage of the magnet down along a vertical steel plate (considering typical friction coefficient). The holding force varies with the gap size between the magnet and the surface.

When placing a holder on a vertical wall (e.g., a car body), it will only hold only about 20%-30% of its nominal power. Gravity as well as a low friction coefficient cause that magnets move down faster than they pop off the substrate. Want to create a hanger? Remember that the shear force is much weaker than the perpendicular breakaway force. On a smooth steel, the magnet will slide down under a significantly smaller load. Utilizing a rubberized pad can effectively raise the stability.

A too thin steel is not enough to conduct the entire magnetic field, which weakens actual performance of the magnet. If you attach a powerful product to a thin surface, the field will penetrate right through and the pull force will drop sharply. To achieve 100% of this neodymium's potential, you need a suitably thick piece of steel. The saturation phenomenon causes that on thin elements (e.g., thin profiles), the holder shows lower pull force. We suggest choosing the steel thickness based on the following data.

Standard neodymium magnets change their properties strength above the temperature limit. Watch out for overheating – excessive heat can irreversibly destroy this magnet. With increasing heat, the magnet's force temporarily drops. Do not use this magnet near heat sources exceeding its safe range. Exceeding the critical threshold will lead to permanent loss of magnetic properties.
*Technical advisory: Temperature resistance is determined by both grade, as well as the dimension ratios. Low-profile magnets (pancake types) risk losing magnetic properties under lower heat stress than long magnets. Red status in the table indicates permanent field degradation for this particular item.

Two strong neodymiums attract each other from a wider radius than a neodymium and metal setup. The setup of two magnets generates a stronger field and a further horizon of performance. Want to build a solid fastener? Utilize two neodymiums instead of one magnet and a striker plate. Exercise caution that when connecting a pair of magnets, the pinch force is extreme. The levitation is slightly lower than the attraction, but still large.
*Flux density between like poles reaches ~0 Gs in the exact middle of the gap (resulting from vector opposition).
* Estimates demonstrate friction force of a pair of identical magnets (friction coefficient ~0.15 for Ni-Ni plating).

Powerful magnet radiation is a serious hazard to electronics as well as pacemakers. These neodymiums produce a field that prevents correct functioning of sensitive medical devices. Be aware: the invisible magnetic field acts through matter and housings. Special caution must be exercised by people with hearing aids and drug dispensers. Also at risk are: mechanical watches, remotes, membranes, and displays. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Neodymium magnets are very brittle – a strong collision with metal can result in shattering. Pay attention to connection velocity – a neodymium left loose becomes dangerous. Striking energy can trigger coating fragments or painful pinches to fingers. Hold the magnet firmly during mounting so it doesn't hit with great force against the steel surface. A collision at high speed means shattering of the neodymium. Wear eye protection when handling with large magnets.

1. Shear force

*Note: On a vertical wall, the magnet retains just approx. 20-30% of its nominal pull.

2. Steel thickness impact

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

3. Heat tolerance

*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) = 0.44

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 offered product is an incredibly powerful cylinder magnet, manufactured from durable NdFeB material, which, at dimensions of Ø12x4 mm, guarantees optimal power. This specific item is characterized by a tolerance of ±0.1mm and professional build quality, making it a perfect solution for professional engineers and designers. As a magnetic rod with significant force (approx. 4.68 kg), this product is available off-the-shelf from our European logistics center, ensuring rapid 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.
This model is created for building electric motors, advanced sensors, and efficient magnetic separators, where field concentration on a small surface counts. Thanks to the high power of 45.89 N with a weight of only 3.39 g, this cylindrical magnet is indispensable in miniature devices 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., 12.1 mm) using two-component 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 durability of the connection.
Grade N38 is the most frequently chosen standard for professional neodymium magnets, offering an optimal price-to-power ratio and high resistance to demagnetization. If you need even stronger magnets in the same volume (Ø12x4), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.
The presented product is a neodymium magnet with precisely defined parameters: diameter 12 mm and height 4 mm. The key parameter here is the lifting capacity amounting to approximately 4.68 kg (force ~45.89 N), which, with such defined dimensions, proves the high grade of the NdFeB material. The product has a [NiCuNi] coating, which protects the surface 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 12 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 diametrically if your project requires it.

Pros as well as cons of neodymium magnets.

Advantages

Apart from their consistent holding force, neodymium magnets have these key benefits:
  • They have stable power, and over more than 10 years their attraction force decreases symbolically – ~1% (in testing),
  • They possess excellent resistance to magnetic field loss as a result of opposing magnetic fields,
  • The use of an elegant layer of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
  • They are known for high magnetic induction at the operating surface, which improves attraction properties,
  • Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
  • Thanks to flexibility in forming and the capacity to adapt to client solutions,
  • Wide application in electronics industry – they find application in hard drives, brushless drives, advanced medical instruments, and industrial machines.
  • Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Limitations

Disadvantages of NdFeB magnets:
  • They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also increases its resistance to damage
  • NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
  • When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
  • We suggest a housing - magnetic mount, due to difficulties in creating threads inside the magnet and complex shapes.
  • Health risk resulting from small fragments of magnets pose a threat, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small elements of these devices can complicate diagnosis medical after entering the body.
  • With large orders the cost of neodymium magnets can be a barrier,

Pull force analysis

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

The load parameter shown refers to the limit force, measured under optimal environment, namely:
  • with the contact of a sheet made of special test steel, guaranteeing maximum field concentration
  • with a cross-section of at least 10 mm
  • characterized by lack of roughness
  • with total lack of distance (no paint)
  • during detachment in a direction perpendicular to the mounting surface
  • in stable room temperature

Determinants of practical lifting force of a magnet

It is worth knowing that the application force will differ influenced by elements below, starting with the most relevant:
  • Distance (between the magnet and the plate), as even a very small clearance (e.g. 0.5 mm) can cause a reduction in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
  • Angle of force application – maximum parameter is reached only during perpendicular pulling. The shear force of the magnet along the surface is standardly several times lower (approx. 1/5 of the lifting capacity).
  • Element thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
  • Material type – ideal substrate is pure iron steel. Hardened steels may have worse magnetic properties.
  • Plate texture – smooth surfaces ensure maximum contact, which increases field saturation. Rough surfaces weaken the grip.
  • Temperature influence – hot environment weakens magnetic field. Too high temperature can permanently damage the magnet.

Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under shearing force the load capacity is reduced by as much as 75%. Moreover, even a minimal clearance between the magnet and the plate reduces the holding force.

Precautions when working with NdFeB magnets
Impact on smartphones

Remember: neodymium magnets generate a field that interferes with sensitive sensors. Maintain a separation from your phone, tablet, and GPS.

Heat sensitivity

Do not overheat. NdFeB magnets are sensitive to heat. If you require operation above 80°C, look for HT versions (H, SH, UH).

Powerful field

Before use, read the rules. Sudden snapping can destroy the magnet or injure your hand. Think ahead.

Safe distance

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

Bone fractures

Large magnets can crush fingers in a fraction of a second. Do not place your hand betwixt two strong magnets.

Risk of cracking

Watch out for shards. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. Wear goggles.

Dust explosion hazard

Fire hazard: Rare earth powder is highly flammable. Do not process magnets in home conditions as this risks ignition.

Choking Hazard

Neodymium magnets are not intended for children. Swallowing a few magnets can lead to them pinching intestinal walls, which constitutes a direct threat to life and requires immediate surgery.

Implant safety

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

Skin irritation risks

Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If skin irritation happens, immediately stop working with magnets and wear gloves.
