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 decreases significantly with every subsequent millimeter of spacing. Note that even a microscopic distance (e.g., contamination, paint, veneer) significantly reduces the pull force. Neodymiums work optimally at the point of direct contact; air break nullifies the power. Observe how quickly the load capacity fall, when the magnet does not adhere tightly to the steel surface. When calculating the mounting, avoid unnecessary gaps.

This section shows the approximate shear load required to start the shifting of the magnet down against a vertical steel plate (considering typical friction coefficient). This parameter varies with the separation distance between the magnet and the metal.

When hanging a element on a vertical plane (e.g., a board), it will only hold just approx. 20%-30% of its maximum pull force. Gravity as well as a low friction coefficient cause that products move down easier than they pull off. Planning a wall mount? Remember that the sliding force is significantly lower than the maximum static pull force. On a painted metal, the element will slide down under a much lighter load. Application of an anti-slip coating can effectively increase the grip.

A thin metal plate cannot take in the entire magnetic field, which wastes potential of the holder. Should you mount a strong magnet to a too thin substrate, the flux will penetrate right through and the holding will be smaller. To achieve 100% of this magnet's potential, you need a suitably thick element of steel. The material oversaturation causes that on delicate walls (e.g., thin profiles), the product works worse. We suggest choosing the steel cross-section from these parameters.

Ordinary NdFeB products change their properties power past the thermal threshold. Watch out for overheating – excessive heat can permanently demagnetize this magnet. With increasing heat, the magnet's force momentarily drops. Avoid using this magnet close to ovens exceeding its safe range. Ignoring the limit will result in permanent loss of magnetism.
*Technical advisory: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Flat magnets (low permeance coefficient) are more susceptible to demagnetization sooner than taller cylinders. Red status in the table signals a risk of irreversible loss for this particular item.

Two strong neodymiums attract each other from a much further distance than a magnet and steel setup. Such a system of two magnets produces a massive flux and a wider radius of performance. Planning to create a strong closure? Apply two magnets instead of a neodymium and a striker plate. Exercise caution that when connecting a pair of magnets, the collision energy is massive. The levitation is marginally weaker than the attraction, but still impressive.
*The magnetic induction between like poles drops to ~0 Gs at the geometric center between the magnets (resulting from vector opposition).
Important: Calculations show sliding force of two identical neodymium magnets (friction ~0.15 for Ni-Ni plating).

Powerful magnet radiation is a real danger to electronics and medical implants. These neodymiums produce a field that prevents correct functioning of digital equipment. Remember: the invisible magnetic field acts through matter and housings. Increased vigilance must be exercised by people with cochlear implants and insulin pumps. The risk also applies to: mechanical watches, remotes, membranes, and displays. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

Magnetic elements are prone to chipping – a violent impact against metal can result in shattering. Watch the impact speed – a neodymium left loose turns into a projectile. Striking energy can trigger coating fragments or dangerous crushing to skin. Hold the magnet firmly during bringing near metal so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h means shattering of the neodymium. Use safety goggles when playing with powerful specimens.

1. Wall mount (shear)

*Caution: On a vertical surface, the magnet retains just a fraction of its nominal pull.

2. Plate thickness effect

*Thin steel (e.g. 0.5mm PC case) significantly limits the holding force.

3. Temperature resistance

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

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.59

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 offered product is an incredibly powerful cylindrical magnet, made from durable NdFeB material, which, with dimensions of Ø8x4 mm, guarantees optimal power. This specific item boasts an accuracy of ±0.1mm and industrial build quality, making it a perfect solution for professional engineers and designers. As a magnetic rod with significant force (approx. 2.04 kg), this product is in stock from our warehouse in Poland, ensuring lightning-fast order fulfillment. Moreover, its Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.
This model is perfect for building electric motors, advanced sensors, and efficient magnetic separators, where field concentration on a small surface counts. Thanks to the pull force of 20.00 N with a weight of only 1.51 g, this cylindrical magnet is indispensable in miniature devices and wherever low weight is crucial.
Due to the brittleness of the NdFeB material, 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 are safe for nickel and fill the gap, guaranteeing durability of the connection.
Grade N38 is the most popular standard for industrial neodymium magnets, offering a great economic balance and operational stability. If you need even stronger magnets in the same volume (Ø8x4), 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 Ø8x4 mm, which, at a weight of 1.51 g, makes it an element with high magnetic energy density. The value of 20.00 N means that the magnet is capable of holding a weight many times exceeding its own mass of 1.51 g. 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 8 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.

Pros and cons of rare earth magnets.

Benefits

Besides their durability, neodymium magnets are valued for these benefits:
  • They retain attractive force for nearly 10 years – the loss is just ~1% (based on simulations),
  • They maintain their magnetic properties even under external field action,
  • By applying a decorative coating of silver, the element has an modern look,
  • The surface of neodymium magnets generates a intense magnetic field – this is one of their assets,
  • Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
  • Thanks to versatility in designing and the ability to adapt to client solutions,
  • Universal use in modern industrial fields – they find application in magnetic memories, electromotive mechanisms, medical equipment, and complex engineering applications.
  • Thanks to their power density, small magnets offer high operating force, occupying minimum space,

Limitations

Disadvantages of neodymium magnets:
  • To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
  • NdFeB magnets lose power 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.
  • Due to limitations in creating threads and complicated shapes in magnets, we propose using a housing - magnetic mechanism.
  • Potential hazard to health – tiny shards of magnets pose a threat, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Additionally, small elements of these devices can be problematic in diagnostics medical in case of swallowing.
  • Due to expensive raw materials, their price exceeds standard values,

Pull force analysis

Highest magnetic holding force – what it depends on?

Breakaway force is the result of a measurement for ideal contact conditions, including:
  • on a base made of structural steel, optimally conducting the magnetic field
  • with a cross-section of at least 10 mm
  • with a surface free of scratches
  • without any insulating layer between the magnet and steel
  • under axial force direction (90-degree angle)
  • at temperature approx. 20 degrees Celsius

Lifting capacity in real conditions – factors

In practice, the actual lifting capacity depends on many variables, listed from most significant:
  • Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
  • Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the maximum value.
  • Plate thickness – insufficiently thick sheet does not accept the full field, causing part of the power to be lost into the air.
  • Chemical composition of the base – low-carbon steel gives the best results. Alloy admixtures lower magnetic properties and lifting capacity.
  • Surface structure – the more even the surface, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
  • Temperature influence – high temperature reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under attempts to slide the magnet the load capacity is reduced by as much as 5 times. In addition, even a minimal clearance between the magnet and the plate reduces the load capacity.

H&S for magnets
Dust explosion hazard

Fire warning: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this may cause fire.

ICD Warning

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

Operating temperature

Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will ruin its properties and pulling force.

Allergy Warning

It is widely known that nickel (standard magnet coating) is a common allergen. For allergy sufferers, prevent touching magnets with bare hands or opt for coated magnets.

Crushing force

Large magnets can crush fingers instantly. Under no circumstances place your hand between two attracting surfaces.

Precision electronics

Note: rare earth magnets generate a field that confuses precision electronics. Keep a separation from your phone, device, and navigation systems.

Keep away from computers

Equipment safety: Neodymium magnets can ruin data carriers and delicate electronics (heart implants, hearing aids, mechanical watches).

Do not underestimate power

Before use, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.

Adults only

Strictly keep magnets away from children. Risk of swallowing is high, and the effects of magnets connecting inside the body are tragic.

Magnet fragility

Beware of splinters. Magnets can explode upon violent connection, launching sharp fragments into the air. Wear goggles.
