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.

Grip strength decreases drastically per each millimeter of gap. Remember that even a very thin break (e.g., contamination, paint, veneer) strongly diminishes the holding power. Magnetic products work strongest at the point of direct contact; air break drastically cuts the power. Observe how flashily the load capacity drop, when the magnet does not touch tightly to the metal substrate. When calculating the arrangement, avoid additional spacers.

The table below defines the theoretical weight limit sufficient to cause the shifting of the magnet vertically along a vertical steel plate (assuming typical friction coefficient). This parameter varies with the distance between the magnet and the surface.

When placing a holder on a vertical wall (e.g., a board), it will only hold just about 20%-30% of nominal attraction strength. Gravity as well as a weak degree of grip mean that holders move down faster than they pop off the substrate. Want to create a wall mount? Note that the shear force is significantly lower than the maximum static pull force. On a slippery surface, the magnet will slide down under a significantly smaller cargo. Application of an anti-slip layer can drastically increase the grip.

A thin metal plate is incapable of conduct the full magnetic flux, which squanders power of the magnet. If you mount a strong magnet to a thin surface, the magnetism will pass right through and the holding will be smaller. To squeeze 100% of this neodymium's potential, you need a suitably thick element of steel. The saturation effect causes that on delicate walls (e.g., appliance housings), the product shows lower pull force. We advise picking the steel cross-section from these parameters.

Standard neodymium magnets lose parameters past the thermal threshold. Avoid high temperatures – high temperature can irreversibly demagnetize this magnet. With every degree above norm, the magnet's force briefly drops. Avoid using this magnet near heat sources exceeding its working range. Exceeding the critical threshold will lead to permanent loss of magnetism.
*Important note: Heat tolerance depends not only on the material grade, as well as the dimension ratios. Thin magnets (low permeance coefficient) may lose charge permanently at lower temperatures than long magnets. Red status in the table indicates a risk of irreversible loss for this particular item.

Two magnets attract each other from a significantly greater distance than a neodymium and metal combination. The setup of two magnets generates a stronger field and a wider radius of action. Want to build a strong closure? Utilize two neodymiums instead of one magnet and a steel. Be careful that when bringing together two magnets, the impact force is massive. The levitation is slightly lower than the attraction, but still impressive.
*The magnetic induction for N-N configuration drops to ~0 Gs in the exact middle between the magnets (resulting from vector opposition).
Note: Estimates apply to sliding force of dual identical magnets (friction ~0.15 for Ni-Ni layer).

A strong magnetic field is a real danger to electronics as well as pacemakers. These magnets produce a field that prevents correct functioning of digital equipment. Remember: the unseen radiation penetrates the body and plastic. Exceptional care must be exercised by people with hearing aids and drug dispensers. Also at risk are: automatic timepieces, remotes, membranes, and displays. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Neodymium magnets are prone to chipping – a violent impact against metal risks their cracking. Watch the impact speed – a magnet released freely speeds with massive force. Striking energy can trigger coating fragments or painful pinches to fingers. Always hold the magnet during mounting so it doesn't hit with great force against the steel surface. A collision at high speed almost guarantees destruction of the neodymium. Wear eye protection when playing with powerful specimens.

1. Sliding resistance

*Note: On a vertical wall, the magnet retains only ~20% of its max power.

2. Steel saturation

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

3. Heat tolerance

*For N38 material, the max working temp is 80°C.

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.71

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, composed of modern NdFeB material, which, with dimensions of Ø14.9x10 mm, guarantees maximum efficiency. The MW 14.9x10 / N38 component boasts high dimensional repeatability and industrial build quality, making it an excellent solution for the most demanding engineers and designers. As a cylindrical magnet with significant force (approx. 7.60 kg), this product is available off-the-shelf from our European logistics center, ensuring quick order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.
It successfully proves itself in DIY projects, advanced robotics, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 74.57 N with a weight of only 13.08 g, this cylindrical magnet is indispensable in electronics and wherever every gram matters.
Due to the brittleness of the NdFeB material, you must not use force-fitting (so-called press-fit), as this risks immediate cracking of this precision component. To ensure stability in automation, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.
Grade N38 is the most frequently chosen standard for industrial neodymium magnets, offering a great economic balance and operational stability. If you need the strongest magnets in the same volume (Ø14.9x10), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.
This model is characterized by dimensions Ø14.9x10 mm, which, at a weight of 13.08 g, makes it an element with impressive magnetic energy density. The key parameter here is the lifting capacity amounting to approximately 7.60 kg (force ~74.57 N), which, with such defined dimensions, proves the high grade of the NdFeB material. The product has a [NiCuNi] coating, which secures it 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 14.9 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.

Pros as well as cons of rare earth magnets.

Benefits

Apart from their notable magnetism, neodymium magnets have these key benefits:
  • Their magnetic field is maintained, and after around ten years it decreases only by ~1% (theoretically),
  • They maintain their magnetic properties even under close interference source,
  • In other words, due to the shiny layer of gold, the element looks attractive,
  • They show high magnetic induction at the operating surface, which increases their power,
  • Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
  • Thanks to versatility in shaping and the capacity to adapt to specific needs,
  • Wide application in future technologies – they are used in magnetic memories, electric motors, advanced medical instruments, also industrial machines.
  • Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in miniature devices

Disadvantages

Disadvantages of neodymium magnets:
  • Brittleness is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a special holder, which not only protects them against impacts but also increases their durability
  • We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
  • When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
  • We suggest cover - magnetic mount, due to difficulties in creating threads inside the magnet and complex shapes.
  • Health risk to health – tiny shards of magnets are risky, when accidentally swallowed, which becomes key in the context of child safety. It is also worth noting that small components of these products can be problematic in diagnostics medical when they are in the body.
  • Due to expensive raw materials, their price is relatively high,

Lifting parameters

Maximum magnetic pulling force – what it depends on?

Information about lifting capacity is the result of a measurement for the most favorable conditions, including:
  • on a base made of mild steel, perfectly concentrating the magnetic flux
  • with a cross-section of at least 10 mm
  • with a plane free of scratches
  • under conditions of ideal adhesion (surface-to-surface)
  • under perpendicular force direction (90-degree angle)
  • in stable room temperature

Practical lifting capacity: influencing factors

During everyday use, the actual lifting capacity depends on many variables, ranked from the most important:
  • Gap (between the magnet and the plate), since even a tiny clearance (e.g. 0.5 mm) can cause a drastic drop in lifting capacity by up to 50% (this also applies to varnish, corrosion or dirt).
  • Force direction – catalog parameter refers to detachment vertically. When attempting to slide, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
  • Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
  • Steel grade – ideal substrate is pure iron steel. Stainless steels may attract less.
  • Surface quality – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Roughness creates an air distance.
  • Temperature influence – hot environment weakens magnetic field. Too high temperature can permanently damage the magnet.

Lifting capacity was measured using a polished steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under shearing force the lifting capacity is smaller. In addition, even a slight gap between the magnet’s surface and the plate lowers the load capacity.

Safety rules for work with NdFeB magnets
Swallowing risk

Adult use only. Small elements pose a choking risk, causing intestinal necrosis. Store out of reach of kids and pets.

Threat to electronics

Powerful magnetic fields can erase data on payment cards, hard drives, and other magnetic media. Keep a distance of at least 10 cm.

Risk of cracking

Neodymium magnets are sintered ceramics, meaning they are fragile like glass. Impact of two magnets leads to them cracking into small pieces.

Operating temperature

Watch the temperature. Exposing the magnet to high heat will ruin its properties and pulling force.

Powerful field

Use magnets consciously. Their powerful strength can shock even experienced users. Stay alert and respect their force.

Warning for allergy sufferers

Some people experience a sensitization to nickel, which is the common plating for NdFeB magnets. Frequent touching might lead to skin redness. We suggest wear protective gloves.

Compass and GPS

A powerful magnetic field interferes with the functioning of magnetometers in phones and navigation systems. Do not bring magnets close to a smartphone to avoid damaging the sensors.

Medical implants

For implant holders: Powerful magnets disrupt electronics. Keep at least 30 cm distance or ask another person to work with the magnets.

Dust explosion hazard

Combustion risk: Rare earth powder is highly flammable. Do not process magnets without safety gear as this risks ignition.

Serious injuries

Protect your hands. Two large magnets will join immediately with a force of massive weight, crushing anything in their path. Be careful!
