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 per each millimeter of distance. Keep in mind that even a microscopic distance (e.g., dirt, paint, dust) noticeably weakens the grip. Magnets work optimally during direct contact; gap kills the power. Notice how flashily the pull force drop, when the magnet does not adhere tightly to the metal substrate. When calculating the arrangement, eliminate additional spacers.

This section calculates the theoretical holding capacity needed to start the downward movement of the magnet down on a vertical steel plate (assuming typical friction). This value varies with the separation distance between the magnet and the metal.

When mounting a holder on a vertical surface (e.g., a car body), it you can count on only approx. 20%-30% of nominal attraction strength. Gravitational force as well as a weak degree of grip cause that magnets move down easier than they detach. Planning a wall mount? Consider that the shear force is noticeably lower than the perpendicular breakaway force. On a slippery surface, the holder will give way down under a significantly smaller cargo. Utilizing a rubberized coating can effectively improve the result.

A thin sheet cannot conduct the full magnetic flux, which wastes potential of the holder. Should you install a neodymium to a thin surface, the magnetism will penetrate right through and the attraction force will be weaker. To squeeze 100% of this magnet's power, you need a suitably thick backing of steel. The saturation phenomenon causes that on thin elements (e.g., car bodies), the product works worse. We recommend selecting the steel cross-section according to the table below.

Ordinary NdFeB products irreversibly lose parameters past the thermal threshold. Protect against heat – high temperature can irreversibly damage this magnet. With every degree above norm, the magnet's force momentarily decreases. Refrain from using this magnet in hot environments exceeding its operating temperature limit. Ignoring the limit will lead to permanent loss of magnetism.
*Important note: Temperature resistance depends not only on the material grade, as well as the dimension ratios. Flat magnets (pancake types) risk losing magnetic properties at lower temperatures than taller cylinders. The danger warning in the table signals permanent field degradation for this specific geometry.

Two magnetic products interact from a wider radius than a magnet and steel setup. Such a system of magnet-to-magnet generates a stronger field and a wider radius of action. Designing a powerful holder? Use a pair of magnets instead of a neodymium and a steel. Be careful that when attracting two neodymiums, the collision energy is extreme. The repulsion force is a bit weaker than the connection force, but still large.
*The magnetic induction for N-N configuration drops to ~0 Gs in the exact middle between the magnets (due to field cancellation).
* Figures show shear force of two identical magnets (friction coefficient ~0.15 for Ni-Ni coating).

Extremely neodym field poses a real danger to IT equipment as well as medical implants. These NdFeB products produce a field that disrupts operation of digital equipment. Be aware: the invisible magnetic field acts through matter and plastic. Special caution must be exercised by people with hearing aids and drug dispensers. The risk also applies to: mechanical watches, remotes, membranes, and displays. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Neodymium magnets are very brittle – a strong collision with metal can result in shattering. Control the attraction moment – a magnet released freely becomes dangerous. Striking energy can destroy the magnet or painful pinches to fingers. Be sure to control the product during mounting so it doesn't hit with great force against the metal. A collision at high speed almost guarantees destruction of the neodymium. Wear eye protection when playing with powerful specimens.

Water displaces steel, making heavy objects slightly lighter. However, remember the water resistance when pulling the rope quickly.

1. Shear force

*Note: On a vertical surface, the magnet retains just approx. 20-30% of its perpendicular strength.

2. Steel saturation

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

3. Power loss vs temp

*For standard magnets, the safety limit 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.

This product is an exceptionally strong cylindrical magnet, produced from modern NdFeB material, which, with dimensions of Ø29.9x10 mm, guarantees maximum efficiency. The MW 29.9x10 / N38 component is characterized by high dimensional repeatability and industrial build quality, making it a perfect solution for the most demanding engineers and designers. As a cylindrical magnet with significant force (approx. 21.50 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring rapid 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 perfect for building generators, advanced Hall effect sensors, and efficient filters, where field concentration on a small surface counts. Thanks to the high power of 210.90 N with a weight of only 52.66 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 recommended way is to glue them into holes with a slightly larger diameter (e.g., 29.9.1 mm) using two-component epoxy glues. To ensure stability in industry, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.
Magnets NdFeB grade N38 are suitable for the majority 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 (Ø29.9x10), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.
The presented product is a neodymium magnet with precisely defined parameters: diameter 29.9 mm and height 10 mm. The key parameter here is the lifting capacity amounting to approximately 21.50 kg (force ~210.90 N), which, with such defined dimensions, proves the high grade of the NdFeB material. The product has a [NiCuNi] coating, which secures it against oxidation, 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 29.9 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 as well as weaknesses of Nd2Fe14B magnets.

Pros

Apart from their consistent power, neodymium magnets have these key benefits:
  • They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
  • Magnets very well protect themselves against loss of magnetization caused by foreign field sources,
  • A magnet with a metallic gold surface has an effective appearance,
  • The surface of neodymium magnets generates a maximum magnetic field – this is a key feature,
  • Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
  • Thanks to modularity in designing and the ability to adapt to client solutions,
  • Huge importance in electronics industry – they are commonly used in mass storage devices, drive modules, diagnostic systems, and technologically advanced constructions.
  • Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which makes them useful in miniature devices

Cons

What to avoid - cons of neodymium magnets and ways of using them
  • At strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
  • 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
  • Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture
  • Due to limitations in creating threads and complicated shapes in magnets, we recommend using a housing - magnetic holder.
  • Health risk to health – tiny shards of magnets are risky, if swallowed, which is particularly important in the context of child safety. Furthermore, small elements of these products are able to complicate diagnosis medical after entering the body.
  • Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Pull force analysis

Highest magnetic holding force – what affects it?

The declared magnet strength represents the peak performance, obtained under optimal environment, namely:
  • using a sheet made of low-carbon steel, functioning as a circuit closing element
  • with a thickness minimum 10 mm
  • with a plane cleaned and smooth
  • under conditions of gap-free contact (metal-to-metal)
  • for force acting at a right angle (in the magnet axis)
  • at ambient temperature approx. 20 degrees Celsius

What influences lifting capacity in practice

Please note that the magnet holding will differ influenced by elements below, starting with the most relevant:
  • Space between surfaces – every millimeter of separation (caused e.g. by varnish or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
  • Loading method – catalog parameter refers to detachment vertically. When applying parallel force, the magnet holds much less (often approx. 20-30% of maximum force).
  • Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
  • Metal type – not every steel attracts identically. Alloy additives weaken the attraction effect.
  • Smoothness – ideal contact is obtained only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
  • Thermal factor – hot environment weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity was determined with the use of a steel plate with a smooth surface of suitable thickness (min. 20 mm), under vertically applied force, in contrast under parallel forces the load capacity is reduced by as much as 5 times. In addition, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.

Safe handling of NdFeB magnets
ICD Warning

Individuals with a heart stimulator have to maintain an large gap from magnets. The magnetic field can disrupt the functioning of the implant.

Material brittleness

NdFeB magnets are ceramic materials, meaning they are very brittle. Clashing of two magnets leads to them cracking into small pieces.

Do not overheat magnets

Standard neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. Damage is permanent.

Protect data

Equipment safety: Strong magnets can damage data carriers and delicate electronics (heart implants, hearing aids, timepieces).

No play value

Strictly store magnets out of reach of children. Choking hazard is high, and the consequences of magnets clamping inside the body are fatal.

Physical harm

Large magnets can break fingers instantly. Under no circumstances place your hand between two strong magnets.

Allergic reactions

Allergy Notice: The nickel-copper-nickel coating consists of nickel. If skin irritation happens, cease handling magnets and use protective gear.

Caution required

Use magnets consciously. Their powerful strength can shock even experienced users. Plan your moves and do not underestimate their force.

Mechanical processing

Mechanical processing of neodymium magnets carries a risk of fire hazard. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.

Compass and GPS

GPS units and smartphones are extremely susceptible to magnetic fields. Direct contact with a strong magnet can decalibrate the sensors in your phone.
