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 drops significantly with every mm of spacing. Note that even the smallest gap (e.g., contamination, paint, veneer) significantly weakens the grip. Magnetic products hold optimally in perfect adhesion; air break weakens the power. Observe how quickly the pull force drop, when the magnet does not adhere flatly to the metal substrate. When calculating the assembly, eliminate redundant distances.

The table below calculates the approximate weight limit required to start the downward movement of the magnet vertically on a upright steel plate (considering standard friction coefficient). The holding force is a function of the gap size between the magnet and the metal.

When mounting a magnet on a upright surface (e.g., a car body), it will only hold only approx. 1/5 of its maximum pull force. Gravity as well as a weak degree of grip cause that magnets move down easier than they pull off. Planning a vertical fastening? Consider that the shear force is much weaker than the maximum static pull force. On a slippery surface, the element will slide down under a significantly smaller weight. Application of an anti-slip pad can effectively improve the result.

A thin metal plate is unable to focus the full magnetic flux, which weakens actual performance of the holder. Should you attach a powerful product to a thin surface, the field will pass right through and the pull force will drop sharply. To achieve the maximum of this magnet's potential, you require a sufficiently solid backing of steel. The saturation effect means that on thin elements (e.g., car bodies), the product shows lower pull force. We suggest choosing the steel dimension based on the following data.

Standard neodymium magnets irreversibly lose strength past the thermal threshold. Protect against heat – excessive heat can irreversibly damage this magnet. With every degree above norm, the neodymium's power briefly decreases. Refrain from using this magnet close to ovens higher than its working range. Exceeding the critical threshold will cause destruction of magnetic properties.
*Important note: Heat tolerance depends not only on the material grade, but also on the magnet's shape. Thin magnets (pancake types) risk losing magnetic properties sooner compared to rod magnets. Red status in the table points to a risk of irreversible loss for this specific geometry.

Two strong neodymiums interact from a much further distance than a neodymium and metal combination. The connection of two magnets produces a massive flux and a further horizon of performance. Want to build a solid fastener? Use a pair of magnets instead of a neodymium and a striker plate. Exercise caution that when bringing together two magnets, the pinch force is massive. The levitation is slightly lower than the connection force, but still significant.
*Field value between like poles drops to ~0 Gs at the geometric center between the magnets (resulting from vector opposition).
Note: Estimates demonstrate sliding force of a pair of same neodymium magnets (friction ~0.15 for Ni-Ni coating).

Neodymium magnets are prone to chipping – a collision with steel can result in shattering. Watch the impact speed – a neodymium left loose turns into a projectile. Kinetic force can destroy the magnet or painful pinches to fingers. Always hold the magnet during installation so it doesn't hit violently against the metal. A collision at high speed almost guarantees destruction of the neodymium. Use safety goggles when handling with large magnets.

Warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!
The magnetic field penetrates through water without any losses. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Shear force

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

2. Efficiency vs thickness

*Thin metal sheet (e.g. computer case) drastically 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 Pc (Permeance Coefficient) = 0.76

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.

This product is an extremely strong plate magnet made of NdFeB material, which, with dimensions of 25x2x6 mm and a weight of 2.25 g, guarantees the highest quality connection. As a magnetic bar with high power (approx. 2.33 kg), this product is available immediately from our warehouse in Poland. Furthermore, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, giving it an aesthetic appearance.
Separating strong flat magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. To separate the MPL 25x2x6 / 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.
They constitute a key element in the production of wind generators and material handling systems. 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 25x2x6 / N38, it is best to use 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 25x2x6 / N38 model is magnetized through the thickness (dimension 6 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 (25x2 mm), which is ideal for flat mounting. This is the most popular configuration for block magnets used in separators and holders.
The presented product is a neodymium magnet with precisely defined parameters: 25 mm (length), 2 mm (width), and 6 mm (thickness). The key parameter here is the lifting capacity amounting to approximately 2.33 kg (force ~22.82 N), which, with such a flat shape, proves the high power of the material. The product meets the standards for N38 grade magnets.

Advantages as well as disadvantages of rare earth magnets.

Strengths

Apart from their notable holding force, neodymium magnets have these key benefits:
  • They do not lose magnetism, even over nearly ten years – the reduction in lifting capacity is only ~1% (based on measurements),
  • They are noted for resistance to demagnetization induced by external field influence,
  • A magnet with a smooth nickel surface has better aesthetics,
  • The surface of neodymium magnets generates a concentrated magnetic field – this is a key feature,
  • Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
  • Considering the ability of precise molding and adaptation to individualized projects, NdFeB magnets can be modeled in a wide range of shapes and sizes, which increases their versatility,
  • Significant place in innovative solutions – they are commonly used in mass storage devices, motor assemblies, diagnostic systems, also modern systems.
  • Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,

Weaknesses

Disadvantages of neodymium magnets:
  • At very strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
  • NdFeB magnets lose force 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
  • When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
  • Due to limitations in creating nuts and complicated forms in magnets, we propose using a housing - magnetic holder.
  • Potential hazard related to microscopic parts of magnets are risky, in case of ingestion, which is particularly important in the context of child health protection. It is also worth noting that small components of these magnets can disrupt the diagnostic process medical after entering the body.
  • High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities

Pull force analysis

Maximum lifting capacity of the magnet – what contributes to it?

Breakaway force was defined for ideal contact conditions, assuming:
  • with the use of a sheet made of low-carbon steel, ensuring maximum field concentration
  • whose transverse dimension equals approx. 10 mm
  • characterized by lack of roughness
  • under conditions of no distance (surface-to-surface)
  • for force acting at a right angle (pull-off, not shear)
  • at temperature approx. 20 degrees Celsius

What influences lifting capacity in practice

Holding efficiency is affected by working environment parameters, including (from most important):
  • Clearance – the presence of foreign body (paint, tape, gap) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
  • Load vector – highest force is obtained only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is typically many times lower (approx. 1/5 of the lifting capacity).
  • Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet restricts the attraction force (the magnet "punches through" it).
  • Metal type – not every steel reacts the same. Alloy additives weaken the interaction with the magnet.
  • Surface condition – ground elements guarantee perfect abutment, which improves field saturation. Rough surfaces reduce efficiency.
  • Temperature influence – hot environment weakens pulling force. Too high temperature can permanently demagnetize the magnet.

Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the holding force is lower. In addition, even a small distance between the magnet’s surface and the plate lowers the holding force.

This is not a toy

Strictly store magnets out of reach of children. Ingestion danger is significant, and the effects of magnets connecting inside the body are very dangerous.

Protect data

Very strong magnetic fields can corrupt files on credit cards, HDDs, and other magnetic media. Maintain a gap of at least 10 cm.

Crushing force

Risk of injury: The attraction force is so immense that it can result in blood blisters, crushing, and broken bones. Protective gloves are recommended.

Eye protection

Watch out for shards. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.

Magnetic interference

An intense magnetic field disrupts the operation of magnetometers in smartphones and GPS navigation. Maintain magnets close to a smartphone to avoid damaging the sensors.

Demagnetization risk

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

Conscious usage

Before starting, read the rules. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.

Warning for allergy sufferers

Some people experience a sensitization to nickel, which is the common plating for NdFeB magnets. Frequent touching can result in skin redness. We strongly advise wear protective gloves.

Fire warning

Fire hazard: Rare earth powder is explosive. Do not process magnets without safety gear as this may cause fire.

Implant safety

People with a heart stimulator must maintain an large gap from magnets. The magnetic field can stop the operation of the life-saving device.
