Magnetic force weakens sharply per each millimeter of distance. Remember that even the smallest gap (e.g., dirt, varnish, rust) strongly reduces the pull force. Magnetic products hold optimally during direct contact; distance nullifies the power. Observe how quickly the load capacity plummet, when the product does not adhere tightly to the steel surface. When planning the mounting, discard redundant distances.

The following data defines the theoretical weight limit required to initiate the sliding of the magnet down against a vertical steel wall (assuming standard friction coefficient). This parameter is relative to the distance between the magnet and the surface.

Table 3: Wall mounting (sliding) - vertical pull
MPL 25x15x2 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.57 kg / 1.25 pounds 567.0 g / 5.6 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.38 kg / 0.83 pounds 378.0 g / 3.7 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.19 kg / 0.42 pounds 189.0 g / 1.9 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.95 kg / 2.08 pounds 945.0 g / 9.3 N

When hanging a element on a vertical wall (e.g., a car body), it will only hold barely about 1/5 of its maximum pull force. Gravity and a low friction coefficient influence the fact that magnets slip faster than they pull off. Want to create a hanger? Consider that the shear force is noticeably lower than the perpendicular breakaway force. On a slippery surface, the holder will slide down under a significantly smaller load. Using a rubber layer can drastically improve the result.

A thin sheet is not enough to focus the full magnetic flux, which wastes potential of the magnet. Should you install a neodymium to a weak sheet, the flux will pass right through and the attraction force will be weaker. To squeeze 100% of this magnet's potential, you need a suitably thick piece of metal. The material oversaturation means that on delicate walls (e.g., thin profiles), the product holds weaker. We recommend selecting the steel cross-section from these parameters.

Classic neodymiums change their properties strength after exceeding the maximum temperature. Protect against heat – high temperature can permanently demagnetize this product. With increasing heat, the magnet's capacity briefly decreases. Do not use this magnet near heat sources exceeding its operating temperature limit. Ignoring the limit will cause destruction of magnetic properties.

*Important note: Thermal stability is determined by both grade, as well as the dimension ratios. Thin magnets (low permeance coefficient) are more susceptible to demagnetization at lower temperatures than long magnets. Warning indicator in the table signals 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 setup of two magnets creates a more powerful interaction and a further horizon of performance. Want to build a strong closure? Use a pair of magnets instead of a neodymium and a striker plate. Exercise caution that when attracting two neodymiums, the pinch force is huge. The repulsion force is slightly lower than the attraction, but still large.
*Field value between like poles is approximately ~0 Gs at the midpoint between the magnets (resulting from vector opposition).
* Results demonstrate friction force of dual same magnets (friction ~0.15 for Ni-Ni coating).

Powerful magnet radiation poses a serious hazard to IT equipment as well as medical implants. These NdFeB products generate a field that disrupts operation of sensitive medical devices. 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: automatic timepieces, remotes, speakers, and screens. Do not bring the product near payment cards, HDD media, or precise measuring instruments.

Table 8: Dynamics (cracking risk) - warning

100 mm	58.43 km/h (16.23 m/s)	0.74 J

NdFeB products are prone to chipping – a collision with steel risks their cracking. Watch the impact speed – a magnet released freely speeds with massive force. Impact energy can cause material chips or dangerous crushing to fingers. Hold the magnet firmly during bringing near metal so it doesn't hit with great force against the steel surface. A collision at high speed almost guarantees destruction of the neodymium. Wear safety glasses when working with powerful specimens.

Corrosion warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

Water displaces steel, making heavy objects slightly lighter. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Vertical hold

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

2. Steel thickness impact

*Thin steel (e.g. 0.5mm PC case) severely limits 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 P_c (Permeance Coefficient) = 0.14

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 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.

Model MPL 25x15x2 / N38 features a low profile and industrial pulling force, making it an ideal solution for building separators and machines. As a magnetic bar with high power (approx. 1.89 kg), this product is available off-the-shelf from our warehouse in Poland. The durable anti-corrosion layer ensures a long lifespan in a dry environment, protecting the core from oxidation.

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 1.89 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 25x15x2 / 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. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.

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 25x15x2 / N38 model is magnetized axially (dimension 2 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 (25x15 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.

This model is characterized by dimensions 25x15x2 mm, which, at a weight of 5.63 g, makes it an element with high energy density. The key parameter here is the lifting capacity amounting to approximately 1.89 kg (force ~18.53 N), which, with such a compact shape, proves the high grade of the material. The product meets the standards for N38 grade magnets.

Strengths and weaknesses of rare earth magnets.

Strengths

Besides their magnetic performance, neodymium magnets are valued for these benefits:

Their magnetic field remains stable, and after approximately ten years it decreases only by ~1% (theoretically),
They are noted for resistance to demagnetization induced by external magnetic fields,
The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to present itself better,
Magnets have maximum magnetic induction on the surface,
Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
Thanks to flexibility in forming and the capacity to modify to complex applications,
Versatile presence in advanced technology sectors – they find application in data components, motor assemblies, medical devices, and multitasking production systems.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which makes them useful in small systems

Disadvantages

Disadvantages of NdFeB magnets:

They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
Limited possibility of making threads in the magnet and complicated forms - recommended is a housing - magnetic holder.
Potential hazard resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which is particularly important in the context of child safety. Furthermore, small elements of these products can be problematic in diagnostics medical when they are in 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

Lifting parameters

Optimal lifting capacity of a neodymium magnet – what affects it?

Holding force of 1.89 kg is a measurement result executed under specific, ideal conditions:

using a sheet made of low-carbon steel, serving as a magnetic yoke
with a cross-section of at least 10 mm
with an polished contact surface
without any air gap between the magnet and steel
under vertical application of breakaway force (90-degree angle)
at room temperature

Determinants of practical lifting force of a magnet

In real-world applications, the actual holding force is determined by several key aspects, presented from the most important:

Space between surfaces – every millimeter of separation (caused e.g. by varnish or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
Force direction – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
Material type – ideal substrate is pure iron steel. Stainless steels may attract less.
Surface condition – ground elements guarantee perfect abutment, which improves field saturation. Rough surfaces weaken the grip.
Thermal conditions – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity was measured with the use of a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under parallel forces the holding force is lower. Additionally, even a slight gap between the magnet and the plate decreases the load capacity.

H&S for magnets

Heat warning

Avoid heat. NdFeB magnets are susceptible to heat. If you require operation above 80°C, look for special high-temperature series (H, SH, UH).

Keep away from computers

Intense magnetic fields can erase data on credit cards, hard drives, and other magnetic media. Keep a distance of min. 10 cm.

Warning for heart patients

Warning for patients: Powerful magnets disrupt medical devices. Maintain minimum 30 cm distance or ask another person to work with the magnets.

Crushing force

Mind your fingers. Two powerful magnets will join immediately with a force of several hundred kilograms, crushing everything in their path. Be careful!

Handling rules

Use magnets with awareness. Their powerful strength can surprise even professionals. Stay alert and do not underestimate their power.

No play value

Adult use only. Tiny parts pose a choking risk, leading to severe trauma. Keep away from kids and pets.

Magnets are brittle

Beware of splinters. Magnets can explode upon violent connection, ejecting sharp fragments into the air. Wear goggles.

Keep away from electronics

GPS units and mobile phones are highly sensitive to magnetic fields. Direct contact with a strong magnet can ruin the internal compass in your phone.

Do not drill into magnets

Fire hazard: Neodymium dust is explosive. Do not process magnets without safety gear as this risks ignition.

Avoid contact if allergic

Certain individuals suffer from a contact allergy to nickel, which is the standard coating for NdFeB magnets. Frequent touching can result in dermatitis. It is best to wear protective gloves.
