Grip strength weakens drastically with every subsequent millimeter of spacing. Keep in mind that even the smallest gap (e.g., dirt, paint, dust) strongly diminishes the holding power. Neodymiums work optimally during direct contact; distance kills the power. Observe how rapidly the pull force plummet, when the product does not adhere tightly to the steel surface. When designing the arrangement, eliminate unnecessary gaps.

The table below presents the approximate shear load needed to cause the sliding of the magnet downwards along a vertical metal surface (assuming typical friction coefficient). The holding force varies with the distance between the magnet and the surface.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MPL 40x10x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	3.55 kg / 7.84 pounds 3555.0 g / 34.9 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	2.37 kg / 5.22 pounds 2370.0 g / 23.2 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	1.19 kg / 2.61 pounds 1185.0 g / 11.6 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	5.93 kg / 13.06 pounds 5925.0 g / 58.1 N

When placing a holder on a upright surface (e.g., a car body), it will only hold barely about 20%-30% of its nominal power. Gravitational force and a weak degree of grip cause that magnets slip faster than they pop off the substrate. Designing a wall mount? Remember that the sliding force is much weaker than the maximum static pull force. On a smooth steel, the magnet will slide down under a significantly smaller cargo. Utilizing a rubberized layer can significantly improve the result.

12 mm	100%	11.85 kg / 26.12 pounds 11850.0 g / 116.2 N

A thin metal plate is not enough to take in the full magnetic flux, which weakens actual performance of the holder. If you mount a strong magnet to a thin surface, the magnetism will penetrate right through and the holding will be smaller. To utilize full efficiency of this neodymium's power, you need a suitably thick backing of steel. The material oversaturation causes that on delicate walls (e.g., thin profiles), the product shows lower pull force. We recommend selecting the steel cross-section according to the table below.

Ordinary NdFeB products change their properties power above the temperature limit. Avoid high temperatures – heat can permanently demagnetize this product. As the temperature rises, the magnet's power momentarily drops. Do not use this magnet in hot environments higher than its safe range. Exceeding the critical threshold will result in irreversible degradation of magnetism.

*Engineering note: Thermal stability is determined by both grade, as well as the dimension ratios. Low-profile magnets (low Pc) may lose charge permanently at lower temperatures than taller cylinders. Warning indicator in the table signals a risk of irreversible loss for this specific geometry.

Two magnetic products attract each other from a wider radius than a magnet and sheet combination. Such a system of magnet-to-magnet creates a more powerful interaction and a larger range of performance. Planning to create a solid fastener? Apply two magnets instead of one magnet and a striker plate. Exercise caution that when connecting a pair of magnets, the pinch force is massive. The levitation is marginally weaker than the connection force, but still impressive.
*The magnetic induction between like poles reaches ~0 Gs in the exact middle between the magnets (caused by magnetic field nullification).
Attention: Calculations apply to friction force of dual matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

Extremely neodym field is a serious hazard to IT equipment and pacemakers. These NdFeB products generate a flux that disrupts operation of sensitive medical devices. Be aware: the unseen radiation penetrates the body and plastic. Special caution must be exercised by people with cochlear implants and drug dispensers. Also at risk are: mechanical watches, remotes, membranes, and screens. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

NdFeB products are prone to chipping – a violent impact against metal causes immediate chipping. Watch the impact speed – a magnet released freely turns into a projectile. 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 ends with a crack of the neodymium. Use safety goggles when playing with powerful specimens.

Rust risk: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

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

1. Shear force

*Caution: On a vertical wall, the magnet holds merely a fraction of its max power.

2. Steel saturation

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

3. Heat tolerance

*For standard magnets, the safety limit is 80°C.

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

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

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.

Component MPL 40x10x5 / N38 features a low profile and industrial 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. 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 11.85 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.

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.

For mounting flat magnets MPL 40x10x5 / N38, we recommend utilizing strong epoxy glues (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).

Standardly, the MPL 40x10x5 / 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 lifting capacity amounting to approximately 11.85 kg (force ~116.27 N), which, with such a flat shape, proves the high grade of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Strengths and weaknesses of Nd₂Fe₁₄B magnets.

Strengths

In addition to their magnetic capacity, neodymium magnets provide the following advantages:

Their magnetic field is maintained, and after approximately 10 years it decreases only by ~1% (theoretically),
Magnets very well resist against demagnetization caused by ambient magnetic noise,
A magnet with a smooth silver surface looks better,
Magnetic induction on the surface of the magnet remains maximum,
Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
Possibility of individual forming as well as adapting to atypical requirements,
Wide application in modern technologies – they are utilized in hard drives, brushless drives, advanced medical instruments, also technologically advanced constructions.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in small systems

Weaknesses

What to avoid - cons of neodymium magnets and ways of using them

To avoid cracks under impact, we suggest using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
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 as well as corrosion.
Due to limitations in producing nuts and complex shapes in magnets, we recommend using casing - magnetic mount.
Potential hazard resulting from small fragments of magnets pose a threat, when accidentally swallowed, which becomes key in the context of child safety. Furthermore, small components of these magnets can be problematic in diagnostics medical after entering the body.
Due to neodymium price, their price is relatively high,

Holding force characteristics

Breakaway strength of the magnet in ideal conditions – what contributes to it?

Magnet power was defined for ideal contact conditions, including:

using a base made of high-permeability steel, serving as a ideal flux conductor
possessing a thickness of minimum 10 mm to avoid saturation
with a surface free of scratches
without any insulating layer between the magnet and steel
for force acting at a right angle (in the magnet axis)
in temp. approx. 20°C

Lifting capacity in real conditions – factors

It is worth knowing that the magnet holding will differ subject to elements below, starting with the most relevant:

Distance (between the magnet and the metal), as even a very small distance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to paint, corrosion or debris).
Loading method – catalog parameter refers to detachment vertically. When applying parallel force, the magnet holds much less (often approx. 20-30% of maximum force).
Steel thickness – insufficiently thick sheet causes magnetic saturation, causing part of the flux to be lost into the air.
Material type – the best choice is pure iron steel. Cast iron may attract less.
Surface condition – ground elements ensure maximum contact, which increases field saturation. Uneven metal reduce efficiency.
Heat – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity was assessed with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under vertically applied force, whereas under shearing force the load capacity is reduced by as much as 75%. Moreover, even a slight gap between the magnet and the plate reduces the holding force.

Precautions when working with NdFeB magnets

Danger to pacemakers

Health Alert: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.

Finger safety

Mind your fingers. Two large magnets will join immediately with a force of massive weight, destroying anything in their path. Exercise extreme caution!

Nickel coating and allergies

Some people have a hypersensitivity to nickel, which is the common plating for neodymium magnets. Extended handling might lead to an allergic reaction. It is best to wear protective gloves.

Heat sensitivity

Regular neodymium magnets (N-type) lose power when the temperature goes above 80°C. The loss of strength is permanent.

Fragile material

Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting shards into the air. Eye protection is mandatory.

This is not a toy

NdFeB magnets are not toys. Eating several magnets can lead to them connecting inside the digestive tract, which constitutes a severe health hazard and necessitates immediate surgery.

Threat to electronics

Powerful magnetic fields can erase data on credit cards, hard drives, and other magnetic media. Maintain a gap of at least 10 cm.

Magnetic interference

GPS units and mobile phones are highly sensitive to magnetic fields. Direct contact with a powerful NdFeB magnet can decalibrate the sensors in your phone.

Do not underestimate power

Use magnets with awareness. Their powerful strength can shock even experienced users. Stay alert and do not underestimate their force.

Fire warning

Dust created during machining of magnets is flammable. Do not drill into magnets unless you are an expert.
