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.

Magnetic force drops significantly with every subsequent millimeter of distance. Note that every additional insulation layer (e.g., contamination, varnish, dust) significantly diminishes the holding power. Magnetic products hold most effectively during direct contact; air break drastically cuts the power. Analyze how quickly the parameters fall, when the magnet does not adhere tightly to the metal substrate. When calculating the mounting, eliminate unnecessary gaps.

The following data calculates the theoretical holding capacity sufficient to cause the sliding of the magnet down against a vertical steel wall (considering typical friction). This value is relative to the gap size between the magnet and the metal.

When hanging a magnet on a vertical plane (e.g., a fridge), it you can count on just approx. 20%-30% of its nominal power. Gravity and a weak degree of grip influence the fact that holders move down easier than they detach. Planning a wall mount? Consider that the shear force is significantly lower than the perpendicular breakaway force. On a slippery surface, the holder will slip down under a significantly smaller cargo. Application of an anti-slip layer can significantly improve the result.

A too thin steel cannot conduct the full magnetic flux, which wastes potential of the holder. Should you install a neodymium to a thin surface, the flux will pass right through and the holding will be smaller. To achieve full efficiency of this neodymium's potential, you require a sufficiently solid element of steel. The material oversaturation causes that on thin elements (e.g., car bodies), the magnet holds weaker. We advise picking the steel cross-section based on the following data.

Standard neodymium magnets irreversibly lose power past the thermal threshold. Avoid high temperatures – heat can irreversibly destroy this magnet. With increasing heat, the neodymium's capacity momentarily decreases. Do not use this magnet close to ovens exceeding its safe range. Too high temperature will lead to permanent loss of magnetism.
*Engineering note: Heat tolerance is determined by both grade, but also on the magnet's shape. Flat magnets (low Pc) are more susceptible to demagnetization under lower heat stress than taller cylinders. The danger warning in the table points to permanent field degradation for this specific geometry.

Two magnetic products attract each other from a significantly greater distance than a neodymium and metal combination. The setup of magnet-to-magnet creates a more powerful interaction and a further horizon of action. Designing a strong closure? Apply two magnets instead of a neodymium and a striker plate. Be careful that when bringing together two magnets, the impact force is huge. The levitation is marginally weaker than the attraction, but still significant.
*The magnetic induction between like poles reaches ~0 Gs at the midpoint between the magnets (due to field cancellation).
Note: Calculations demonstrate friction force of two identical magnets (friction ~0.15 for Ni-Ni plating).

Powerful magnet radiation is a large risk to electronic devices as well as medical implants. These neodymiums produce a field that destroys function of digital equipment. Remember: the invisible magnetic field penetrates the body and housings. Increased vigilance must be exercised by people with hearing aids and drug dispensers. Also at risk are: mechanical watches, remotes, speakers, and displays. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

NdFeB products are very brittle – a collision with steel can result in shattering. Control the attraction moment – a magnet released freely turns into a projectile. Striking energy can destroy the magnet or painful pinches to fingers. Be sure to control the product during installation so it doesn't hit violently against the metal. A collision at high speed means shattering of the magnet. Use safety goggles when working with powerful specimens.

1. Shear force

*Caution: On a vertical surface, the magnet retains just ~20% of its max power.

2. Steel saturation

*Thin metal sheet (e.g. computer case) significantly reduces the holding force.

3. Thermal stability

*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) = 0.29

The chart above illustrates the magnetic characteristics of the material within the second quadrant of the hysteresis loop. 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 cylinder magnet, composed of modern NdFeB material, which, with dimensions of Ø5x1 mm, guarantees the highest energy density. This specific item is characterized by high dimensional repeatability and professional build quality, making it a perfect solution for professional engineers and designers. As a magnetic rod with significant force (approx. 0.32 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 modeling, advanced automation, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 3.12 N with a weight of only 0.15 g, this cylindrical magnet is indispensable in electronics and wherever every gram matters.
Due to the delicate structure of the ceramic sinter, we absolutely advise against force-fitting (so-called press-fit), as this risks chipping the coating of this precision component. To ensure long-term durability in industry, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.
Grade N38 is the most popular standard for professional neodymium magnets, offering an optimal price-to-power ratio and high resistance to demagnetization. If you need the strongest magnets in the same volume (Ø5x1), 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 Ø5x1 mm, which, at a weight of 0.15 g, makes it an element with high magnetic energy density. The key parameter here is the holding force amounting to approximately 0.32 kg (force ~3.12 N), which, with such compact dimensions, proves the high power 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 5 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.

Strengths and weaknesses of Nd2Fe14B magnets.

Pros

In addition to their magnetic capacity, neodymium magnets provide the following advantages:
  • They retain full power for almost ten years – the drop is just ~1% (based on simulations),
  • They are resistant to demagnetization induced by external magnetic fields,
  • The use of an metallic layer of noble metals (nickel, gold, silver) causes the element to have aesthetics,
  • Magnets have exceptionally strong magnetic induction on the surface,
  • Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
  • Considering the ability of precise shaping and adaptation to custom needs, magnetic components can be manufactured in a broad palette of forms and dimensions, which amplifies use scope,
  • Versatile presence in high-tech industry – they are used in magnetic memories, motor assemblies, medical equipment, as well as technologically advanced constructions.
  • Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which allows their use in small systems

Disadvantages

Drawbacks and weaknesses of neodymium magnets and proposals for their use:
  • At strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
  • When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their strength 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
  • When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
  • Limited ability of producing threads in the magnet and complicated shapes - recommended is a housing - magnetic holder.
  • Possible danger to health – tiny shards of magnets pose a threat, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that small components of these devices can be problematic in diagnostics medical when they are in the body.
  • Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Pull force analysis

Maximum holding power of the magnet – what it depends on?

Magnet power was defined for optimal configuration, assuming:
  • using a plate made of low-carbon steel, acting as a magnetic yoke
  • whose thickness is min. 10 mm
  • with an ideally smooth touching surface
  • with direct contact (no coatings)
  • for force acting at a right angle (in the magnet axis)
  • at conditions approx. 20°C

Magnet lifting force in use – key factors

In practice, the real power results from a number of factors, listed from most significant:
  • Distance (betwixt the magnet and the plate), as even a microscopic clearance (e.g. 0.5 mm) leads to a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or dirt).
  • Loading method – catalog parameter refers to detachment vertically. When applying parallel force, the magnet exhibits significantly lower power (typically approx. 20-30% of nominal force).
  • Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of converting into lifting capacity.
  • Steel grade – ideal substrate is pure iron steel. Hardened steels may generate lower lifting capacity.
  • Plate texture – smooth surfaces guarantee perfect abutment, which increases field saturation. Rough surfaces weaken the grip.
  • Thermal environment – heating the magnet causes a temporary drop of force. Check the thermal limit for a given model.

Lifting capacity was assessed with the use of a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, however under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the load capacity.

Precautions when working with NdFeB magnets
Do not underestimate power

Use magnets with awareness. Their huge power can surprise even experienced users. Plan your moves and do not underestimate their force.

Warning for allergy sufferers

Some people suffer from a sensitization to nickel, which is the common plating for neodymium magnets. Frequent touching can result in dermatitis. We recommend wear safety gloves.

Keep away from computers

Device Safety: Strong magnets can ruin payment cards and delicate electronics (heart implants, hearing aids, timepieces).

Flammability

Mechanical processing of NdFeB material poses a fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.

GPS and phone interference

An intense magnetic field interferes with the functioning of magnetometers in smartphones and navigation systems. Maintain magnets near a smartphone to prevent damaging the sensors.

Physical harm

Watch your fingers. Two large magnets will join immediately with a force of several hundred kilograms, destroying everything in their path. Be careful!

Thermal limits

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

Shattering risk

Despite the nickel coating, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.

Health Danger

For implant holders: Powerful magnets affect electronics. Maintain at least 30 cm distance or request help to work with the magnets.

Do not give to children

NdFeB magnets are not intended for children. Swallowing multiple magnets can lead to them connecting inside the digestive tract, which poses a critical condition and necessitates immediate surgery.
