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. Keep in mind that even a microscopic distance (e.g., contamination, paint, dust) noticeably reduces the pull force. Neodymiums hold most effectively in perfect adhesion; gap nullifies the power. Observe how flashily the pull force fall, when the magnet does not adhere tightly to the steel surface. When planning the arrangement, avoid additional spacers.

The following data shows the approximate weight limit required to start the sliding of the magnet down along a upright steel wall (considering standard friction). This parameter is a function of the separation distance between the magnet and the metal.

Table 3: Vertical assembly (sliding) - vertical pull
MW 70x60 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	49.18 kg / 108.42 pounds 49179.0 g / 482.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	32.79 kg / 72.28 pounds 32786.0 g / 321.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	16.39 kg / 36.14 pounds 16393.0 g / 160.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	81.97 kg / 180.70 pounds 81965.0 g / 804.1 N

When placing a element on a upright surface (e.g., a board), it will only hold just approx. 20%-30% of nominal attraction strength. Gravity as well as a low friction coefficient mean that holders slip easier than they pull off. Want to create a hanger? Consider that the sliding force is much weaker than the perpendicular breakaway force. On a slippery surface, the holder will slide down under a much lighter cargo. Application of an anti-slip coating can drastically increase the grip.

A thin sheet is incapable of conduct the entire magnetic field, which squanders power of the magnet. Should you attach a powerful product to a too thin substrate, the magnetism will pass right through and the pull force will drop sharply. To utilize 100% of this neodymium's potential, you require a sufficiently solid backing of steel. The material oversaturation means that on thin elements (e.g., appliance housings), the holder shows lower pull force. We suggest choosing the steel dimension according to the table below.

Standard neodymium magnets lose strength past the thermal threshold. Watch out for overheating – heat can permanently damage this magnet. With increasing heat, the magnet's capacity briefly decreases. Refrain from using this magnet near heat sources exceeding its working range. Exceeding the critical threshold will cause irreversible degradation of magnetism.

*Technical advisory: Thermal stability is determined by both grade, as well as the dimension ratios. Low-profile magnets (low permeance coefficient) risk losing magnetic properties under lower heat stress compared to rod magnets. Red status in the table indicates permanent field degradation for this specific geometry.

Two magnets interact from a wider radius than a neodymium and metal combination. The setup of magnet-to-magnet produces a massive flux and a wider radius of action. Want to build a solid fastener? Use a pair of magnets instead of one magnet and a striker plate. Exercise caution that when attracting two neodymiums, the pinch force is massive. The levitation is a bit weaker than the connection force, but still significant.
*Field value in repulsion mode drops to ~0 Gs at the geometric center between the magnets (caused by magnetic field nullification).
* Calculations show sliding force of a pair of identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

Extremely neodym field is a real danger to electronics and pacemakers. These NdFeB products produce a field that destroys function of sensitive medical devices. Be aware: the unseen radiation penetrates the body and housings. Special caution must be exercised by people with hearing aids and insulin pumps. Also at risk are: mechanical watches, remotes, membranes, and displays. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

Table 8: Impact energy (kinetic energy) - collision effects
MW 70x60 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	13.35 km/h (3.71 m/s)	11.92 J
30 mm	17.44 km/h (4.84 m/s)	20.32 J
50 mm	18.17 km/h (5.05 m/s)	22.06 J
100 mm	18.41 km/h (5.12 m/s)	22.66 J

NdFeB products are very brittle – a violent impact against metal can result in shattering. Pay attention to connection velocity – a neodymium left loose speeds with massive force. Kinetic force can trigger coating fragments or painful pinches to skin. Hold the magnet firmly during bringing near metal so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h ends with a crack of the neodymium. Use safety goggles when working with powerful specimens.

Corrosion warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

In water, the magnet feels stronger thanks to Archimedes' principle. However, remember the water resistance when pulling the rope quickly.

1. Wall mount (shear)

*Warning: On a vertical surface, the magnet holds just ~20% of its perpendicular strength.

2. Steel saturation

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

3. Thermal stability

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.82

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 P_c (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 P_c 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 exceptionally strong cylinder magnet, manufactured from durable NdFeB material, which, with dimensions of Ø70x60 mm, guarantees maximum efficiency. This specific item is characterized by an accuracy of ±0.1mm and industrial build quality, making it a perfect solution for the most demanding engineers and designers. As a cylindrical magnet with impressive force (approx. 163.93 kg), this product is in stock from our European logistics center, ensuring lightning-fast order fulfillment. Moreover, its 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 1608.16 N with a weight of only 1731.8 g, this rod is indispensable in miniature devices 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 professional component. To ensure long-term durability in automation, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.

Grade N38 is the most popular standard for industrial neodymium magnets, offering an optimal price-to-power ratio and high resistance to demagnetization. If you need the strongest magnets in the same volume (Ø70x60), 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 Ø70x60 mm, which, at a weight of 1731.8 g, makes it an element with high magnetic energy density. The key parameter here is the holding force amounting to approximately 163.93 kg (force ~1608.16 N), which, with such compact 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 70 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 Nd₂Fe₁₄B magnets.

Pros

In addition to their long-term stability, neodymium magnets provide the following advantages:

They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (in laboratory conditions),
They are noted for resistance to demagnetization induced by external field influence,
By using a smooth coating of nickel, the element presents an nice look,
Magnets have excellent magnetic induction on the active area,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
Possibility of custom machining and optimizing to precise applications,
Universal use in high-tech industry – they serve a role in data components, electromotive mechanisms, medical equipment, as well as multitasking production systems.
Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,

Limitations

Disadvantages of NdFeB magnets:

At strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
They rust in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
We suggest cover - magnetic holder, due to difficulties in realizing nuts inside the magnet and complex forms.
Potential hazard to health – tiny shards of magnets can be dangerous, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Additionally, small elements of these magnets can disrupt the diagnostic process medical after entering the body.
With mass production the cost of neodymium magnets is a challenge,

Lifting parameters

Magnetic strength at its maximum – what it depends on?

Information about lifting capacity is the result of a measurement for the most favorable conditions, assuming:

on a block made of mild steel, effectively closing the magnetic flux
whose thickness equals approx. 10 mm
characterized by lack of roughness
with total lack of distance (no coatings)

Determinants of lifting force in real conditions

It is worth knowing that the magnet holding will differ influenced by elements below, starting with the most relevant:

Gap (betwixt the magnet and the plate), because even a tiny clearance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
Direction of force – maximum parameter is reached only during pulling at a 90° angle. The force required to slide of the magnet along the surface is usually several times lower (approx. 1/5 of the lifting capacity).
Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
Steel grade – ideal substrate is pure iron steel. Stainless steels may attract less.
Plate texture – smooth surfaces ensure maximum contact, which increases field saturation. Rough surfaces weaken the grip.
Thermal environment – heating the magnet results in weakening of force. Check the maximum operating temperature for a given model.

Lifting capacity was assessed using a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, however under shearing force the holding force is lower. Moreover, even a slight gap between the magnet and the plate reduces the lifting capacity.

Safety rules for work with NdFeB magnets

ICD Warning

People with a heart stimulator must maintain an large gap from magnets. The magnetism can interfere with the functioning of the implant.

Dust explosion hazard

Fire warning: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this risks ignition.

Do not give to children

Neodymium magnets are not toys. Swallowing a few magnets may result in them connecting inside the digestive tract, which constitutes a direct threat to life and requires urgent medical intervention.

Safe operation

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

Heat sensitivity

Watch the temperature. Exposing the magnet above 80 degrees Celsius will destroy its magnetic structure and pulling force.

Hand protection

Pinching hazard: The attraction force is so great that it can result in hematomas, crushing, and even bone fractures. Protective gloves are recommended.

Sensitization to coating

It is widely known that the nickel plating (standard magnet coating) is a potent allergen. If your skin reacts to metals, avoid direct skin contact or choose coated magnets.

Magnetic interference

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

Protect data

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

Eye protection

Beware of splinters. Magnets can fracture upon violent connection, launching sharp fragments into the air. Eye protection is mandatory.
