Magnetic force weakens sharply with every subsequent millimeter of distance. Remember that even a microscopic distance (e.g., contamination, paint, dust) noticeably diminishes the holding power. Magnetic products operate most effectively in perfect adhesion; gap drastically cuts the force. Observe how flashily the parameters drop, when the product does not touch tightly to the steel surface. When calculating the assembly, eliminate redundant distances.

The following data calculates the theoretical holding capacity needed to initiate the sliding of the magnet vertically against a upright steel wall (considering standard friction coefficient). This value depends on the air gap between the magnet and the metal.

Table 3: Vertical assembly (sliding) - vertical pull
MPL 40x18x10 SH / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	7.14 kg / 15.75 pounds 7143.0 g / 70.1 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	4.76 kg / 10.50 pounds 4762.0 g / 46.7 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	2.38 kg / 5.25 pounds 2381.0 g / 23.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	11.91 kg / 26.25 pounds 11905.0 g / 116.8 N

When placing a element on a upright surface (e.g., a car body), it you can count on just about 20%-30% of its nominal power. Gravity and a low friction coefficient cause that magnets move down easier than they pop off the substrate. Designing a vertical fastening? Consider that the shear force is noticeably lower than the maximum static pull force. On a painted metal, the element will slip down under a noticeably lighter cargo. Using a rubber coating can effectively raise the stability.

A too thin steel is unable to absorb the entire magnetic field, which wastes potential of the holder. Should you mount a strong magnet to a weak sheet, the field will penetrate right through and the holding will be smaller. To utilize the maximum of this magnet's power, you need a suitably thick backing of metal. The saturation effect means that on delicate walls (e.g., appliance housings), the product shows lower pull force. We suggest choosing the steel dimension according to the table below.

Standard neodymium magnets irreversibly lose power past the thermal threshold. Protect against heat – high temperature can permanently damage this magnet. As the temperature rises, the neodymium's capacity temporarily lowers. Refrain from using this product near heat sources higher than its safe range. Exceeding the critical threshold will result in permanent loss of magnetic properties.

*Engineering note: Heat tolerance is determined by both grade, and the Permeance Coefficient Pc. Flat magnets (low permeance coefficient) risk losing magnetic properties sooner compared to rod magnets. Red status in the table signals permanent field degradation for this particular item.

Two magnetic products attract each other from a significantly greater distance than a magnet and steel setup. The connection of magnet-to-magnet produces a massive flux and a wider radius of operation. Want to build a powerful holder? Apply two magnets instead of a neodymium and a steel. Remember that when connecting a pair of magnets, the impact force is huge. The repulsion force is a bit weaker than the connection force, but still large.
*The magnetic induction for N-N configuration is approximately ~0 Gs at the geometric center between the magnets (resulting from vector opposition).
Note: Figures refer to friction force of dual identical magnets (friction ~0.15 for Ni-Ni layer).

Powerful magnet radiation poses a real danger to electronics as well as medical implants. These NdFeB products generate a flux that prevents correct functioning of sensitive medical devices. Notice: the invisible magnetic field passes through tissues and plastic. Exceptional care must be exercised by people with hearing aids and drug dispensers. Also at risk are: automatic timepieces, remotes, membranes, and displays. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Table 8: Dynamics (cracking risk) - collision effects
MPL 40x18x10 SH / N38

Start from (mm)	Speed (km/h)	Energy (J)

50 mm	47.37 km/h (13.16 m/s)	4.67 J
100 mm	66.97 km/h (18.60 m/s)	9.34 J

NdFeB products are delicate – a violent impact against metal causes immediate chipping. Pay attention to connection velocity – a neodymium left loose turns into a projectile. Kinetic force can cause material chips or painful pinches to fingers. Always hold the magnet during installation so it doesn't hit with great force against the steel surface. A collision at high speed ends with a crack of the magnet. Wear safety glasses when playing with large magnets.

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

In water, the magnet feels stronger thanks to Archimedes' principle. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Vertical hold

*Note: On a vertical wall, the magnet holds just approx. 20-30% of its perpendicular strength.

2. Plate thickness effect

*Thin steel (e.g. computer case) significantly limits the holding force.

3. Temperature resistance

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.43

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 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.

This product is a very powerful magnet in the shape of a plate made of NdFeB material, which, with dimensions of 40x18x10 mm and a weight of 54 g, guarantees the highest quality connection. This rectangular block with a force of 233.58 N is ready for shipment in 24h, allowing for rapid realization of your project. The durable anti-corrosion layer ensures a long lifespan in a dry environment, protecting the core from oxidation.

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 23.81 kg can pinch very hard and cause hematomas. Using a screwdriver risks destroying the coating and permanently cracking the magnet.

They constitute a key element in the production of generators and material handling systems. 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. Double-sided tape cushions vibrations, which is an advantage when mounting in moving elements. Avoid chemically aggressive glues or hot glue, which can demagnetize neodymium (above 80°C).

Standardly, the MPL 40x18x10 SH / N38 model is magnetized through the thickness (dimension 10 mm), which means that the N and S poles are located on its largest, flat surfaces. 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 40x18x10 mm, which, at a weight of 54 g, makes it an element with high energy density. The key parameter here is the holding force amounting to approximately 23.81 kg (force ~233.58 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 rare earth magnets.

Benefits

In addition to their long-term stability, neodymium magnets provide the following advantages:

They have stable power, and over nearly 10 years their performance decreases symbolically – ~1% (according to theory),
They show high resistance to demagnetization induced by external disturbances,
By applying a smooth layer of nickel, the element gains an elegant look,
The surface of neodymium magnets generates a powerful magnetic field – this is one of their assets,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
Possibility of precise forming as well as optimizing to complex applications,
Huge importance in high-tech industry – they find application in hard drives, brushless drives, advanced medical instruments, as well as other advanced devices.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which enables their usage in compact constructions

Disadvantages

Characteristics of disadvantages of neodymium magnets: application proposals

They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects the magnet but also improves its resistance to damage
Neodymium magnets decrease their power 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 durability even at temperatures up to 230°C
They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
We recommend a housing - magnetic holder, due to difficulties in creating threads inside the magnet and complicated forms.
Health risk resulting from small fragments of magnets pose a threat, if swallowed, which becomes key in the context of child safety. Furthermore, tiny parts of these products are able to complicate diagnosis medical in case of swallowing.
High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities

Holding force characteristics

Magnetic strength at its maximum – what it depends on?

The declared magnet strength represents the peak performance, recorded under laboratory conditions, specifically:

with the contact of a sheet made of low-carbon steel, ensuring full magnetic saturation
whose transverse dimension is min. 10 mm
with an ideally smooth touching surface
under conditions of gap-free contact (surface-to-surface)
during pulling in a direction vertical to the mounting surface
in stable room temperature

Determinants of lifting force in real conditions

It is worth knowing that the working load may be lower depending on the following factors, in order of importance:

Space between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
Force direction – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet holds much less (typically approx. 20-30% of maximum force).
Plate thickness – insufficiently thick sheet causes magnetic saturation, causing part of the flux to be wasted into the air.
Steel grade – the best choice is high-permeability steel. Stainless steels may generate lower lifting capacity.
Base smoothness – the more even the plate, the better the adhesion and stronger the hold. Roughness creates an air distance.
Heat – NdFeB sinters have a negative temperature coefficient. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).

Lifting capacity testing was conducted on a smooth plate of optimal thickness, under a perpendicular pulling force, whereas under parallel forces the holding force is lower. Moreover, even a slight gap between the magnet and the plate reduces the holding force.

Warnings

Threat to electronics

Do not bring magnets close to a purse, laptop, or screen. The magnetism can destroy these devices and wipe information from cards.

Pacemakers

For implant holders: Strong magnetic fields disrupt electronics. Keep at least 30 cm distance or request help to work with the magnets.

Do not underestimate power

Before use, check safety instructions. Sudden snapping can break the magnet or hurt your hand. Be predictive.

Hand protection

Mind your fingers. Two large magnets will snap together instantly with a force of massive weight, crushing anything in their path. Exercise extreme caution!

Keep away from electronics

A strong magnetic field negatively affects the operation of compasses in phones and GPS navigation. Keep magnets close to a device to avoid breaking the sensors.

Nickel coating and allergies

It is widely known that the nickel plating (the usual finish) is a strong allergen. If you have an allergy, avoid direct skin contact and select coated magnets.

No play value

Absolutely store magnets out of reach of children. Choking hazard is significant, and the consequences of magnets connecting inside the body are fatal.

Do not overheat magnets

Keep cool. NdFeB magnets are sensitive to temperature. If you need resistance above 80°C, look for special high-temperature series (H, SH, UH).

Risk of cracking

NdFeB magnets are ceramic materials, which means they are prone to chipping. Clashing of two magnets leads to them shattering into small pieces.

Machining danger

Drilling and cutting of NdFeB material carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
