Frequently asked questions

How much will a block magnet really hold?
The catalogue force is measured in full contact with smooth steel at least 10 mm thick, pulled perpendicular, at about 20 °C. On 1 mm sheet about 50% of that value remains, on 0.5 mm about 25%. Mounted on a vertical wall the realistic figure is 20–30%, because the load is then in shear rather than in tension.
What is the maximum working temperature?
Standard N-series grades up to 80 °C, and N50, N52 and N54 up to 60 °C. Above the maximum working temperature the loss stops being reversible. The Curie temperature, at which magnetic properties are lost completely, is about 310 °C.
What safety factor should I allow?
At least twice the mass of the item, and three to five times for vertical mounting. The margin covers sheet thickness, surface condition, any layer of paint or rust, and vibration.

Magnetic force weakens drastically with every mm of gap. Keep in mind that every additional insulation layer (e.g., contamination, paint, dust) significantly weakens the grip. Magnetic products operate most effectively during direct contact; distance nullifies the power. Observe how rapidly the parameters plummet, when the product does not touch tightly to the metal substrate. When designing the assembly, discard redundant distances.

The following data indicates the estimated shear load necessary to start the shifting of the magnet downwards along a upright steel plate (assuming standard friction). The holding force depends on the separation distance between the magnet and the surface.

When placing a holder on a upright plane (e.g., a car body), it you can count on barely about 20%-30% of its nominal power. Gravity as well as a weak degree of grip cause that holders move down faster than they detach. Planning a vertical fastening? Consider that the shear force is much weaker than the perpendicular breakaway force. On a slippery surface, the element will slip down under a significantly smaller load. Application of an anti-slip coating can effectively increase the grip.

A thin metal plate is not enough to focus the full magnetic flux, which weakens actual performance of the magnet. If you attach a powerful product to a thin surface, the field will pass right through and the pull force will drop sharply. To achieve 100% of this neodymium's potential, you need a suitably thick piece of metal. The material oversaturation means that on sheet metal structures (e.g., appliance housings), the product works worse. We advise picking the steel cross-section according to the table below.

Ordinary NdFeB products lose parameters above the temperature limit. Protect against heat – high temperature can irreversibly damage this product. As the temperature rises, the magnet's force momentarily lowers. Do not use this product in hot environments exceeding its working range. Exceeding the critical threshold will lead to permanent loss of magnetic properties.
*Engineering note: Thermal stability depends not only on the material grade, but also on the magnet's shape. Low-profile magnets (low permeance coefficient) may lose charge permanently sooner than long magnets. Warning indicator in the table signals permanent field degradation for this particular item.

Two strong neodymiums interact from a significantly greater distance than a magnet and sheet combination. The connection of magnet-to-magnet creates a more powerful interaction and a wider radius of performance. Designing a solid fastener? Apply two magnets instead of a neodymium and a steel. Be careful that when connecting a pair of magnets, the impact force is huge. The levitation is marginally weaker than the connection force, but still impressive.
*The magnetic induction for N-N configuration is approximately ~0 Gs in the exact middle of the gap (due to field cancellation).
* Estimates show sliding force of a pair of identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

Powerful magnet radiation poses a real danger to electronics and medical implants. These NdFeB products produce a field that disrupts operation of digital equipment. Remember: the unseen radiation penetrates the body and plastic. Special caution must be exercised by people with cochlear implants and drug dispensers. Also at risk are: mechanical watches, remotes, membranes, and displays. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

NdFeB products are delicate – a violent impact against metal can result in shattering. Pay attention to connection velocity – a neodymium left loose speeds with massive force. Impact energy can destroy the magnet or dangerous crushing to skin. 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. Use safety goggles when working with large magnets.

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

1. Vertical hold

*Warning: On a vertical wall, the magnet holds just approx. 20-30% of its nominal pull.

2. Steel thickness impact

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

3. Heat tolerance

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

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.26

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.

This product is a very powerful magnet in the shape of a plate made of NdFeB material, which, with dimensions of 60x10x5 mm and a weight of 22.5 g, guarantees premium class connection. This rectangular block with a force of 178.10 N is ready for shipment in 24h, allowing for rapid realization of your project. Additionally, its Ni-Cu-Ni coating protects it against corrosion in standard operating conditions, giving it an aesthetic appearance.
The key to success is sliding the magnets along their largest connection plane (using e.g., the edge of a table), which is easier than trying to tear them apart directly. Watch your fingers! Magnets with a force of 18.16 kg can pinch very hard and cause hematomas. Never use metal tools for prying, as the brittle NdFeB material may chip and damage your eyes.
Plate magnets MPL 60x10x5 / N38 are the foundation for many industrial devices, such as filters catching filings and linear motors. Thanks to the flat surface and high force (approx. 18.16 kg), they are ideal as hidden locks in furniture making and mounting elements in automation. Customers often choose this model for workshop organization on strips and for advanced DIY and modeling projects, where precision and power count.
Cyanoacrylate glues (super glue type) are good only for small magnets; for larger plates, we recommend resins. For lighter applications or mounting on smooth surfaces, branded foam tape (e.g., 3M VHB) will work, provided the surface is perfectly degreased. Avoid chemically aggressive glues or hot glue, which can demagnetize neodymium (above 80°C).
Standardly, the MPL 60x10x5 / N38 model is magnetized axially (dimension 5 mm), which means that the N and S poles are located on its largest, flat surfaces. In practice, this means that this magnet has the greatest attraction force on its main planes (60x10 mm), which is ideal for flat mounting. This is the most popular configuration for block magnets used in separators and holders.
This model is characterized by dimensions 60x10x5 mm, which, at a weight of 22.5 g, makes it an element with high energy density. The key parameter here is the lifting capacity amounting to approximately 18.16 kg (force ~178.10 N), which, with such a compact shape, proves the high grade of the material. The product meets the standards for N38 grade magnets.

Advantages as well as disadvantages of Nd2Fe14B magnets.

Benefits

Besides their immense strength, neodymium magnets offer the following advantages:
  • They do not lose strength, even after nearly 10 years – the decrease in power is only ~1% (theoretically),
  • Magnets effectively protect themselves against loss of magnetization caused by foreign field sources,
  • By using a smooth coating of silver, the element acquires an modern look,
  • The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
  • Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
  • Thanks to versatility in designing and the capacity to modify to unusual requirements,
  • Key role in modern technologies – they find application in hard drives, brushless drives, advanced medical instruments, also modern systems.
  • Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Limitations

Disadvantages of NdFeB magnets:
  • Brittleness is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a special holder, which not only protects them against impacts but also increases their durability
  • We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we recommend 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.
  • Due to limitations in realizing nuts and complicated forms in magnets, we propose using casing - magnetic holder.
  • Potential hazard resulting from small fragments of magnets can be dangerous, if swallowed, which is particularly important in the context of child safety. Additionally, small components of these magnets can disrupt the diagnostic process medical when they are in the body.
  • Due to neodymium price, their price is relatively high,

Holding force characteristics

Maximum lifting capacity of the magnet – what affects it?

The lifting capacity listed is a result of laboratory testing performed under specific, ideal conditions:
  • on a base made of structural steel, effectively closing the magnetic flux
  • whose transverse dimension reaches at least 10 mm
  • characterized by even structure
  • under conditions of no distance (metal-to-metal)
  • under vertical force vector (90-degree angle)
  • at standard ambient temperature

Magnet lifting force in use – key factors

Please note that the working load will differ influenced by the following factors, starting with the most relevant:
  • Distance – existence of any layer (rust, dirt, gap) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
  • Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
  • Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
  • Plate material – mild steel attracts best. Alloy admixtures lower magnetic properties and lifting capacity.
  • Base smoothness – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
  • Thermal environment – temperature increase results in weakening of induction. Check the maximum operating temperature for a given model.

Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under shearing force the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the load capacity.

Warnings
Do not overheat magnets

Keep cool. NdFeB magnets are susceptible to temperature. If you require operation above 80°C, inquire about special high-temperature series (H, SH, UH).

Eye protection

Despite the nickel coating, the material is delicate and not impact-resistant. Do not hit, as the magnet may crumble into sharp, dangerous pieces.

Product not for children

These products are not toys. Accidental ingestion of a few magnets can lead to them connecting inside the digestive tract, which constitutes a direct threat to life and requires urgent medical intervention.

Health Danger

Warning for patients: Powerful magnets disrupt electronics. Keep minimum 30 cm distance or request help to handle the magnets.

Handling rules

Use magnets consciously. Their powerful strength can shock even professionals. Be vigilant and do not underestimate their force.

Combustion hazard

Combustion risk: Rare earth powder is highly flammable. Do not process magnets in home conditions as this risks ignition.

Metal Allergy

It is widely known that nickel (the usual finish) is a potent allergen. If you have an allergy, prevent touching magnets with bare hands and choose versions in plastic housing.

Crushing risk

Large magnets can smash fingers in a fraction of a second. Under no circumstances place your hand betwixt two attracting surfaces.

Electronic hazard

Do not bring magnets near a purse, computer, or screen. The magnetism can irreversibly ruin these devices and wipe information from cards.

Magnetic interference

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