Pulling power decreases sharply with every mm of gap. Keep in mind that even the smallest gap (e.g., contamination, paint, veneer) significantly reduces the pull force. Magnetic products work strongest during direct contact; distance weakens the power. Observe how rapidly the pull force plummet, when the product does not adhere flatly to the steel surface. When calculating the arrangement, discard additional spacers.

The table below shows the estimated force necessary to cause the sliding of the magnet vertically along a upright steel wall (considering typical friction coefficient). The holding force varies with the separation distance between the magnet and the surface.

When hanging a magnet on a vertical plane (e.g., a board), it will only hold barely about 1/5 of nominal attraction strength. Gravitational force and a weak degree of grip influence the fact that magnets move down faster than they pull off. Designing a wall mount? Remember that the sliding force is much weaker than the maximum static pull force. On a slippery surface, the element will slide down under a noticeably lighter weight. Using a rubber coating can drastically increase the grip.

A thin sheet is unable to conduct the full magnetic flux, which weakens actual performance of the magnet. Should you attach a powerful product to a too thin substrate, the flux will penetrate right through and the pull force will drop sharply. To utilize full efficiency of this magnet's power, you need a suitably thick piece of steel. The saturation phenomenon causes that on sheet metal structures (e.g., appliance housings), the magnet works worse. We recommend selecting the steel dimension from these parameters.

Classic neodymiums lose parameters above the temperature limit. Watch out for overheating – high temperature can irreversibly demagnetize this magnet. With every degree above norm, the magnet's power temporarily lowers. Refrain from using this magnet close to ovens higher than its working range. Ignoring the limit will cause permanent loss of magnetism.

*Technical advisory: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Thin magnets (low permeance coefficient) risk losing magnetic properties under lower heat stress than taller cylinders. Warning indicator in the table indicates permanent field degradation for this specific geometry.

Two magnetic products attract each other from a much further distance than a neodymium and metal combination. The setup of magnet-to-magnet produces a massive flux and a further horizon of performance. Planning to create a strong closure? Use a pair of magnets instead of a neodymium and a steel. Exercise caution that when bringing together two magnets, the impact force is massive. The repulsion force is a bit weaker than the attraction, but still significant.
*The magnetic induction between like poles is approximately ~0 Gs in the exact middle between the magnets (due to field cancellation).
* Results refer to sliding force of dual same neodymium magnets (friction ~0.15 for Ni-Ni layer).

Extremely neodym field is a serious hazard to electronic devices and medical implants. These magnets produce a field that destroys function of sensitive medical devices. Remember: the invisible magnetic field passes through tissues and plastic. Exceptional care must be exercised by people with hearing aids and insulin pumps. The risk also applies to: mechanical watches, remotes, speakers, and displays. Do not bring the product near payment cards, HDD media, or precise measuring instruments.

Magnetic elements are prone to chipping – a strong collision with metal causes immediate chipping. Pay attention to connection velocity – a magnet released freely becomes dangerous. Kinetic force 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 magnet. Wear eye protection when working 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.

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

*Note: On a vertical wall, the magnet holds merely approx. 20-30% of its max power.

2. Steel saturation

*Thin steel (e.g. computer case) drastically weakens the holding force.

3. Temperature resistance

*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) = 0.26

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.

40.59 ZŁ brutto / pcs

This product is a very powerful magnet in the shape of a plate made of NdFeB material, which, with dimensions of 40x10x4 mm and a weight of 12 g, guarantees premium class connection. As a magnetic bar with high power (approx. 9.31 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 shifting 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. To separate the MPL 40x10x4 / 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.

Plate magnets MPL 40x10x4 / 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 hanging tools on strips and for advanced DIY and modeling projects, where precision and power count.

For mounting flat magnets MPL 40x10x4 / N38, it is best to use 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).

The magnetic axis runs through the shortest dimension, which is typical for gripper magnets. 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 4 mm (thickness). It is a magnetic block with dimensions 40x10x4 mm and a self-weight of 12 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Pros as well as cons of Nd₂Fe₁₄B magnets.

Pros

In addition to their pulling strength, neodymium magnets provide the following advantages:

They do not lose magnetism, even over approximately 10 years – the decrease in strength is only ~1% (based on measurements),
They maintain their magnetic properties even under external field action,
In other words, due to the smooth finish of nickel, the element gains a professional look,
They feature high magnetic induction at the operating surface, which increases their power,
Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
Considering the possibility of accurate forming and adaptation to custom solutions, NdFeB magnets can be manufactured in a variety of geometric configurations, which makes them more universal,
Versatile presence in advanced technology sectors – they are utilized in mass storage devices, electromotive mechanisms, medical devices, as well as multitasking production systems.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which allows their use in compact constructions

Limitations

Characteristics of disadvantages of neodymium magnets: weaknesses and usage proposals

They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects 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 force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
Due to limitations in producing nuts and complex shapes in magnets, we propose using casing - magnetic mount.
Possible danger related to microscopic parts of magnets are risky, when accidentally swallowed, which gains importance in the context of child health protection. It is also worth noting that tiny parts of these products can complicate diagnosis medical when they are in the body.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Holding force characteristics

Maximum lifting force for a neodymium magnet – what it depends on?

Breakaway force is the result of a measurement for the most favorable conditions, including:

with the application of a sheet made of special test steel, guaranteeing full magnetic saturation
whose transverse dimension is min. 10 mm
with a plane perfectly flat
under conditions of gap-free contact (surface-to-surface)
for force acting at a right angle (in the magnet axis)
at ambient temperature room level

Determinants of practical lifting force of a magnet

Real force impacted by specific conditions, including (from most important):

Clearance – the presence of any layer (paint, dirt, gap) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
Material type – ideal substrate is pure iron steel. Cast iron may generate lower lifting capacity.
Smoothness – full contact is obtained only on smooth steel. Rough texture reduce the real contact area, reducing force.
Temperature – heating the magnet causes a temporary drop of induction. Check the maximum operating temperature for a given model.

Lifting capacity was assessed using a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, whereas under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a small distance between the magnet and the plate lowers the lifting capacity.

Safe handling of NdFeB magnets

Machining danger

Machining of neodymium magnets carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.

Serious injuries

Watch your fingers. Two powerful magnets will snap together instantly with a force of several hundred kilograms, destroying anything in their path. Be careful!

Medical interference

For implant holders: Strong magnetic fields disrupt electronics. Keep at least 30 cm distance or ask another person to handle the magnets.

GPS Danger

Navigation devices and smartphones are highly susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can permanently damage the sensors in your phone.

Electronic devices

Avoid bringing magnets near a wallet, computer, or TV. The magnetic field can destroy these devices and wipe information from cards.

Metal Allergy

Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction appears, cease working with magnets and wear gloves.

Shattering risk

Neodymium magnets are sintered ceramics, which means they are very brittle. Impact of two magnets leads to them breaking into small pieces.

Conscious usage

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

No play value

Absolutely store magnets away from children. Choking hazard is significant, and the effects of magnets clamping inside the body are very dangerous.

Permanent damage

Standard neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. Damage is permanent.
