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.

Grip strength weakens drastically with every mm of spacing. Note that even a very thin break (e.g., contamination, varnish, dust) strongly diminishes the holding power. Magnets hold optimally during direct contact; distance drastically cuts the power. Notice how rapidly the load capacity fall, when the magnet does not adhere directly to the steel surface. When calculating the assembly, eliminate redundant distances.

When placing a holder on a upright plane (e.g., a fridge), it will maintain only approx. 20%-30% of its maximum pull force. Gravitational force and a low friction coefficient cause that holders slip easier than they pop off the substrate. Planning a wall mount? Consider that the sliding force is much weaker than the maximum static pull force. On a painted metal, the holder will give way down under a significantly smaller weight. Utilizing a rubberized coating can drastically improve the result.

A too thin steel is incapable of conduct the entire magnetic field, which weakens actual performance of the holder. Should you install a neodymium to a thin surface, the flux will penetrate right through and the holding will be smaller. To squeeze full efficiency of this magnet's potential, you require a sufficiently solid piece of steel. The material oversaturation means that on thin elements (e.g., car bodies), the product shows lower pull force. We recommend selecting the steel cross-section based on the following data.

Standard neodymium magnets lose power above the temperature limit. Watch out for overheating – excessive heat can permanently demagnetize this magnet. As the temperature rises, the neodymium's capacity briefly drops. Refrain from using this magnet close to ovens exceeding its safe range. Ignoring the limit will lead to destruction of magnetic properties.
*Engineering note: Heat tolerance is determined by both grade, and the Permeance Coefficient Pc. Low-profile magnets (low Pc) may lose charge permanently sooner than long magnets. Warning indicator in the table points to a risk of irreversible loss for this specific geometry.

Two strong neodymiums attract each other from a significantly greater distance than a magnet and sheet setup. The connection of magnet-to-magnet produces a massive flux and a larger range of performance. Designing a strong closure? Use a pair of magnets instead of one magnet and a striker plate. Exercise caution that when connecting a pair of magnets, the collision energy is massive. The repulsion force is slightly lower than the attraction, but still significant.
*The magnetic induction in repulsion mode drops to ~0 Gs at the geometric center of the gap (resulting from vector opposition).
* Figures apply to sliding force of dual matching magnets (friction coefficient ~0.15 for Ni-Ni layer).

A strong magnetic field poses a serious hazard to IT equipment and pacemakers. These NdFeB products produce a flux that prevents correct functioning of sensitive medical devices. Be aware: the unseen radiation passes through tissues and plastic. Special caution must be exercised by people with cochlear implants and insulin pumps. Also at risk are: automatic timepieces, remotes, speakers, and displays. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Neodymium magnets are delicate – a collision with steel can result in shattering. Pay attention to connection velocity – a magnet released freely becomes dangerous. Kinetic force can destroy the magnet or painful pinches to skin. Always hold the magnet during mounting so it doesn't hit violently against the metal. A collision at high speed almost guarantees destruction of the magnet. Use safety goggles when working with large magnets.

1. Shear force

*Warning: On a vertical surface, the magnet holds merely ~20% of its max power.

2. Plate thickness effect

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

3. Power loss vs temp

*For standard magnets, the max working temp is 80°C.

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.31

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 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.

Model MPL 40x10x5x2[7/3.5] / N38 features a low profile and professional pulling force, making it a perfect solution for building separators and machines. This rectangular block with a force of 116.27 N is ready for shipment in 24h, allowing for rapid realization of your project. Furthermore, its Ni-Cu-Ni coating protects it against corrosion in standard operating conditions, giving it an aesthetic appearance.
Separating block magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. To separate the MPL 40x10x5x2[7/3.5] / N38 model, firmly slide one magnet over the edge of the other until the attraction force decreases. We recommend care, because after separation, the magnets may want to violently snap back together, which threatens pinching the skin. Using a screwdriver risks destroying the coating and permanently cracking the magnet.
Plate magnets MPL 40x10x5x2[7/3.5] / N38 are the foundation for many industrial devices, such as filters catching filings and linear motors. They work great as fasteners under tiles, wood, or glass. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.
For mounting flat magnets MPL 40x10x5x2[7/3.5] / N38, we recommend utilizing strong epoxy glues (e.g., UHU Endfest, Distal), which ensure a durable bond with metal or plastic. Double-sided tape cushions vibrations, which is an advantage when mounting in moving elements. Remember to roughen and wash the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.
Standardly, the MPL 40x10x5x2[7/3.5] / 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 (40x10 mm), which is ideal for flat mounting. Such a pole arrangement ensures maximum holding capacity when pressing against the sheet, creating a closed magnetic circuit.
The presented product is a neodymium magnet with precisely defined parameters: 40 mm (length), 10 mm (width), and 5 mm (thickness). The key parameter here is the holding force amounting to approximately 11.85 kg (force ~116.27 N), which, with such a flat shape, proves the high power of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Strengths and weaknesses of rare earth magnets.

Advantages

Besides their high retention, neodymium magnets are valued for these benefits:
  • They retain attractive force for around 10 years – the loss is just ~1% (based on simulations),
  • They have excellent resistance to magnetism drop when exposed to external magnetic sources,
  • In other words, due to the smooth finish of nickel, the element becomes visually attractive,
  • Neodymium magnets achieve maximum magnetic induction on a small area, which ensures high operational effectiveness,
  • Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
  • Thanks to modularity in forming and the ability to customize to client solutions,
  • Versatile presence in electronics industry – they serve a role in magnetic memories, brushless drives, medical equipment, also technologically advanced constructions.
  • Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Disadvantages

Disadvantages of NdFeB magnets:
  • Brittleness is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a steel housing, which not only secures them against impacts but also raises their durability
  • Neodymium magnets lose force 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
  • They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
  • Limited possibility of making nuts in the magnet and complex forms - preferred is casing - mounting mechanism.
  • Possible danger related to microscopic parts 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 economically unviable,

Pull force analysis

Detachment force of the magnet in optimal conditions – what it depends on?

The force parameter is a result of laboratory testing executed under specific, ideal conditions:
  • on a base made of mild steel, optimally conducting the magnetic field
  • whose transverse dimension equals approx. 10 mm
  • with a surface cleaned and smooth
  • without any insulating layer between the magnet and steel
  • under axial application of breakaway force (90-degree angle)
  • at ambient temperature room level

Practical lifting capacity: influencing factors

In real-world applications, the real power is determined by many variables, ranked from the most important:
  • Gap between surfaces – every millimeter of separation (caused e.g. by varnish or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
  • Angle of force application – highest force is available only during perpendicular pulling. The shear force of the magnet along the plate is standardly many times smaller (approx. 1/5 of the lifting capacity).
  • Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of converting into lifting capacity.
  • Steel type – low-carbon steel attracts best. Alloy steels lower magnetic permeability and holding force.
  • Surface condition – ground elements guarantee perfect abutment, which increases field saturation. Rough surfaces reduce efficiency.
  • Thermal factor – high temperature reduces pulling force. Too high temperature can permanently damage the magnet.

Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Moreover, even a slight gap between the magnet and the plate reduces the holding force.

H&S for magnets
Heat warning

Standard neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. Damage is permanent.

Do not give to children

Only for adults. Tiny parts pose a choking risk, leading to severe trauma. Keep away from children and animals.

Data carriers

Avoid bringing magnets near a wallet, computer, or TV. The magnetic field can destroy these devices and erase data from cards.

Fragile material

Despite metallic appearance, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.

Fire risk

Combustion risk: Neodymium dust is explosive. Avoid machining magnets in home conditions as this may cause fire.

Impact on smartphones

A strong magnetic field negatively affects the operation of compasses in smartphones and navigation systems. Keep magnets near a smartphone to prevent damaging the sensors.

Do not underestimate power

Exercise caution. Neodymium magnets attract from a distance and snap with massive power, often faster than you can move away.

Bodily injuries

Watch your fingers. Two large magnets will snap together immediately with a force of massive weight, destroying everything in their path. Exercise extreme caution!

Nickel coating and allergies

Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If redness occurs, immediately stop working with magnets and use protective gear.

Health Danger

Individuals with a heart stimulator should maintain an safe separation from magnets. The magnetic field can disrupt the operation of the life-saving device.
