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 weakens drastically with every subsequent millimeter of distance. Remember that even a microscopic distance (e.g., contamination, varnish, dust) significantly diminishes the holding power. Magnetic products operate optimally during direct contact; air break weakens the force. Notice how flashily the parameters drop, when the product does not touch tightly to the metal substrate. When designing the mounting, discard redundant distances.

The following data defines the approximate force required to cause the shifting of the magnet vertically against a vertical metal surface (assuming typical friction). This value depends on the separation distance between the magnet and the surface.

When hanging a element on a vertical surface (e.g., a car body), it you can count on barely about 1/5 of its nominal power. Gravitational force and a weak degree of grip mean that magnets slide down faster than they pull off. Want to create a wall mount? Consider that the sliding force is noticeably lower than the maximum static pull force. On a smooth steel, the element will slip down under a noticeably lighter cargo. Application of an anti-slip coating can significantly improve the result.

A thin sheet is unable to take in the full magnetic flux, which weakens actual performance of the magnet. If you install a neodymium to a weak sheet, the magnetism will penetrate right through and the holding will be smaller. To achieve 100% of this neodymium's potential, you need a suitably thick piece of metal. The material oversaturation causes that on sheet metal structures (e.g., appliance housings), the holder holds weaker. We suggest choosing the steel thickness according to the table below.

Standard neodymium magnets change their properties power past the thermal threshold. Avoid high temperatures – high temperature can permanently destroy this product. With increasing heat, the neodymium's capacity temporarily decreases. Do not use this product close to heaters higher than its safe range. Exceeding the critical threshold will lead to destruction of magnetic properties.
*Important note: Thermal stability depends not only on the material grade, and the Permeance Coefficient Pc. Thin magnets (pancake types) may lose charge permanently sooner than long magnets. Red status in the table indicates a risk of irreversible loss for this particular item.

Two magnets interact from a much further distance than a magnet and sheet setup. Such a system of magnet-to-magnet produces a massive flux and a wider radius of operation. Planning to create a powerful holder? Utilize two neodymiums instead of a neodymium and a steel. Remember that when bringing together two magnets, the pinch force is extreme. The repulsion force is a bit weaker than the connection force, but still large.
*Flux density between like poles reaches ~0 Gs in the exact middle of the gap (due to field cancellation).
Attention: Results show sliding force of dual identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni plating).

Powerful magnet radiation is a serious hazard to electronic devices and medical implants. These neodymiums generate a flux that destroys function of digital equipment. Remember: the unseen radiation passes through tissues and glass. Exceptional care must be taken by people with hearing aids and insulin pumps. Influence will be felt by: mechanical watches, car keys, speakers, and screens. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Neodymium magnets are delicate – a strong collision with metal risks their cracking. Watch the impact speed – a neodymium left loose becomes dangerous. Impact energy can destroy the magnet or injury to skin. Hold the magnet firmly during mounting so it doesn't hit with great force against the steel surface. A collision at high speed almost guarantees destruction of the magnet. Wear eye protection when playing with large magnets.

1. Wall mount (shear)

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

2. Steel thickness impact

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

3. Thermal stability

*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) = 0.11

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 an exceptionally strong rod magnet, manufactured from modern NdFeB material, which, with dimensions of Ø15x1 mm, guarantees maximum efficiency. The MW 15x1 / N38 model boasts an accuracy of ±0.1mm and industrial build quality, making it an ideal solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 0.44 kg), this product is in stock from our warehouse in Poland, ensuring rapid order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.
It finds application in DIY projects, advanced robotics, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 4.29 N with a weight of only 1.33 g, this rod 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 immediate cracking of this professional component. To ensure long-term durability in automation, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.
Magnets N38 are strong enough for 90% of applications in automation and machine building, where excessive miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø15x1), 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 15 mm and height 1 mm. The value of 4.29 N means that the magnet is capable of holding a weight many times exceeding its own mass of 1.33 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 15 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 through the diameter if your project requires it.

Advantages and disadvantages of neodymium magnets.

Pros

In addition to their pulling strength, neodymium magnets provide the following advantages:
  • They have stable power, and over more than 10 years their performance decreases symbolically – ~1% (according to theory),
  • Neodymium magnets are remarkably resistant to loss of magnetic properties caused by external interference,
  • Thanks to the reflective finish, the surface of nickel, gold, or silver-plated gives an modern appearance,
  • Magnets possess huge magnetic induction on the outer layer,
  • Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
  • Thanks to versatility in designing and the capacity to customize to individual projects,
  • Universal use in future technologies – they find application in computer drives, electromotive mechanisms, advanced medical instruments, also other advanced devices.
  • Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which enables their usage in miniature devices

Weaknesses

Drawbacks and weaknesses of neodymium magnets and proposals for their use:
  • At very strong impacts they can crack, 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 strength. 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
  • When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
  • We recommend casing - magnetic mechanism, due to difficulties in realizing threads inside the magnet and complicated shapes.
  • Possible danger resulting from small fragments of magnets pose a threat, in case of ingestion, which gains importance in the context of child safety. Furthermore, 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

Holding force characteristics

Optimal lifting capacity of a neodymium magnet – what affects it?

The specified lifting capacity refers to the maximum value, measured under laboratory conditions, specifically:
  • using a sheet made of low-carbon steel, functioning as a magnetic yoke
  • with a cross-section of at least 10 mm
  • with an ideally smooth contact surface
  • with zero gap (without impurities)
  • during pulling in a direction perpendicular to the mounting surface
  • in stable room temperature

What influences lifting capacity in practice

In practice, the actual holding force is determined by a number of factors, presented from crucial:
  • Air gap (betwixt the magnet and the plate), as even a microscopic distance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to paint, rust or dirt).
  • Loading method – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet holds much less (typically approx. 20-30% of maximum force).
  • Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
  • Plate material – mild steel attracts best. Higher carbon content lower magnetic permeability and lifting capacity.
  • Plate texture – smooth surfaces ensure maximum contact, which improves force. Uneven metal weaken the grip.
  • Thermal factor – high temperature reduces pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.

Lifting capacity was measured by applying a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under parallel forces the holding force is lower. In addition, even a small distance between the magnet’s surface and the plate reduces the holding force.

H&S for magnets
Swallowing risk

Absolutely keep magnets away from children. Ingestion danger is high, and the consequences of magnets connecting inside the body are fatal.

Fire risk

Powder produced during cutting of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.

Compass and GPS

Be aware: rare earth magnets produce a field that disrupts sensitive sensors. Keep a separation from your phone, device, and GPS.

Protect data

Do not bring magnets near a wallet, laptop, or TV. The magnetic field can destroy these devices and wipe information from cards.

Pinching danger

Big blocks can smash fingers in a fraction of a second. Never place your hand betwixt two attracting surfaces.

Risk of cracking

Neodymium magnets are ceramic materials, which means they are fragile like glass. Collision of two magnets will cause them cracking into shards.

Handling guide

Use magnets with awareness. Their powerful strength can surprise even experienced users. Stay alert and do not underestimate their power.

Medical implants

Medical warning: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have electronic implants.

Operating temperature

Avoid heat. NdFeB magnets are susceptible to temperature. If you need operation above 80°C, ask us about HT versions (H, SH, UH).

Avoid contact if allergic

It is widely known that nickel (standard magnet coating) is a potent allergen. For allergy sufferers, prevent direct skin contact or opt for coated magnets.
