Pulling power drops significantly with every mm of gap. Keep in mind that even the smallest gap (e.g., dirt, varnish, rust) significantly diminishes the holding power. Neodymiums hold most effectively at the point of direct contact; gap drastically cuts the force. Observe how rapidly the pull force drop, when the product does not adhere tightly to the steel surface. When planning the arrangement, discard redundant distances.

The table below presents the approximate force needed to initiate the downward movement of the magnet vertically against a upright steel wall (considering standard friction). The holding force depends on the gap size between the magnet and the metal.

When mounting a element on a vertical plane (e.g., a car body), it will maintain barely approx. 1/5 of its nominal power. Gravitational force and a weak degree of grip mean that products slip easier than they pop off the substrate. Planning a hanger? Consider that the shear force is significantly lower than the maximum static pull force. On a slippery surface, the element will slip down under a significantly smaller cargo. Application of an anti-slip coating can significantly raise the stability.

A thin metal plate cannot absorb the full magnetic flux, which weakens actual performance of the holder. If you install a neodymium to a too thin substrate, the flux will penetrate right through and the attraction force will be weaker. To squeeze 100% of this neodymium's power, you require a sufficiently solid backing of steel. The saturation phenomenon causes that on delicate walls (e.g., appliance housings), the magnet holds weaker. We recommend selecting the steel dimension according to the table below.

Classic neodymiums lose power after exceeding the maximum temperature. Watch out for overheating – excessive heat can permanently demagnetize this magnet. As the temperature rises, the neodymium's force momentarily decreases. Do not use this magnet in hot environments higher than its working range. Exceeding the critical threshold will cause irreversible degradation of magnetic properties.
*Engineering note: Temperature resistance depends not only on the material grade, as well as the dimension ratios. Low-profile magnets (low permeance coefficient) may lose charge permanently sooner than taller cylinders. Warning indicator in the table points to a risk of irreversible loss for this particular item.

Two magnets interact from a wider radius than a magnet and steel setup. Such a system of magnet-to-magnet creates a more powerful interaction and a wider radius of operation. Designing a strong closure? Apply two magnets instead of one magnet and a striker plate. Remember that when bringing together two magnets, the impact force is huge. The levitation is a bit weaker than the attraction, but still significant.
*Field value in repulsion mode reaches ~0 Gs at the geometric center of the gap (due to field cancellation).
Attention: Estimates show sliding force of two matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni plating).

A strong magnetic field is a real danger to IT equipment as well as pacemakers. These NdFeB products generate a flux that destroys function of digital equipment. Be aware: the invisible magnetic field passes through tissues and glass. Exceptional care must be taken by people with hearing aids and insulin pumps. Also at risk are: mechanical watches, car keys, speakers, and displays. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Magnetic elements are prone to chipping – a violent impact against metal can result in shattering. Watch the impact speed – a neodymium left loose speeds with massive force. Impact energy can destroy the magnet or dangerous crushing to skin. Be sure to control the product during mounting so it doesn't slam with momentum against the metal. A collision at high speed means shattering of the neodymium. Wear eye protection when working with large magnets.

Warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.
Contrary to myths, water does not block the magnetic field. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.
1. Sliding resistance

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

2. Steel thickness impact

*Thin steel (e.g. computer case) severely reduces the holding force.

3. Temperature resistance

*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) = 0.46

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 an extremely strong magnet in the shape of a plate made of NdFeB material, which, with dimensions of 30x5x5 mm and a weight of 5.63 g, guarantees the highest quality connection. This rectangular block with a force of 68.96 N is ready for shipment in 24h, allowing for rapid realization of your project. Additionally, its Ni-Cu-Ni coating secures 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. Watch your fingers! Magnets with a force of 7.03 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 30x5x5 / N38 are the foundation for many industrial devices, such as filters catching filings and linear motors. They work great as invisible mounts under tiles, wood, or glass. Customers often choose this model for workshop organization on strips and for advanced DIY and modeling projects, where precision and power count.
For mounting flat magnets MPL 30x5x5 / N38, we recommend utilizing two-component adhesives (e.g., UHU Endfest, Distal), which ensure a durable bond with metal or plastic. 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).
The magnetic axis runs through the shortest dimension, which is typical for gripper magnets. Thanks to this, it works best when "sticking" to sheet metal or another magnet with a large surface area. Such a pole arrangement ensures maximum holding capacity when pressing against the sheet, creating a closed magnetic circuit.
This model is characterized by dimensions 30x5x5 mm, which, at a weight of 5.63 g, makes it an element with impressive energy density. The key parameter here is the holding force amounting to approximately 7.03 kg (force ~68.96 N), which, with such a compact shape, proves the high power of the material. The product meets the standards for N38 grade magnets.

Strengths and weaknesses of neodymium magnets.

Advantages

Apart from their notable magnetic energy, neodymium magnets have these key benefits:
  • They do not lose magnetism, even over nearly ten years – the reduction in power is only ~1% (theoretically),
  • Magnets effectively protect themselves against demagnetization caused by external fields,
  • In other words, due to the metallic finish of gold, the element gains a professional look,
  • Magnetic induction on the working layer of the magnet is maximum,
  • 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 flexibility in constructing and the ability to adapt to complex applications,
  • Versatile presence in electronics industry – they find application in HDD drives, motor assemblies, medical equipment, also multitasking production systems.
  • Thanks to their power density, small magnets offer high operating force, occupying minimum space,

Weaknesses

Disadvantages of NdFeB magnets:
  • At very strong impacts they can crack, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
  • We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
  • They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
  • Limited possibility of producing threads in the magnet and complicated shapes - preferred is cover - magnetic holder.
  • Health risk resulting from small fragments of magnets pose a threat, in case of ingestion, which gains importance in the aspect of protecting the youngest. It is also worth noting that small components of these devices are able to complicate diagnosis medical in case of swallowing.
  • Due to neodymium price, their price is higher than average,

Holding force characteristics

Highest magnetic holding force – what affects it?

Magnet power was defined for ideal contact conditions, including:
  • on a plate made of mild steel, effectively closing the magnetic field
  • with a cross-section of at least 10 mm
  • with an ground touching surface
  • under conditions of ideal adhesion (metal-to-metal)
  • under vertical application of breakaway force (90-degree angle)
  • at conditions approx. 20°C

Practical lifting capacity: influencing factors

It is worth knowing that the working load may be lower influenced by the following factors, in order of importance:
  • Distance – the presence of any layer (paint, tape, gap) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
  • Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
  • Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
  • Metal type – not every steel attracts identically. Alloy additives weaken the attraction effect.
  • Base smoothness – the more even the surface, the better the adhesion and stronger the hold. Unevenness creates an air distance.
  • Temperature influence – high temperature reduces pulling force. Too high temperature can permanently demagnetize the magnet.

Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under shearing force the holding force is lower. Moreover, even a slight gap between the magnet’s surface and the plate reduces the holding force.

Precautions when working with neodymium magnets
Safe distance

Very strong magnetic fields can corrupt files on credit cards, hard drives, and other magnetic media. Keep a distance of at least 10 cm.

Crushing force

Risk of injury: The pulling power is so great that it can result in hematomas, pinching, and even bone fractures. Use thick gloves.

This is not a toy

Neodymium magnets are not suitable for play. Eating a few magnets can lead to them attracting across intestines, which constitutes a severe health hazard and requires immediate surgery.

Powerful field

Handle magnets with awareness. Their powerful strength can surprise even experienced users. Plan your moves and do not underestimate their power.

Permanent damage

Do not overheat. NdFeB magnets are sensitive to heat. If you need resistance above 80°C, inquire about HT versions (H, SH, UH).

Magnets are brittle

Neodymium magnets are sintered ceramics, meaning they are very brittle. Impact of two magnets will cause them breaking into small pieces.
