Pulling power decreases sharply with every mm of distance. Keep in mind that even a very thin break (e.g., contamination, paint, dust) noticeably weakens the grip. Neodymiums hold most effectively at the point of direct contact; distance drastically cuts the power. See how flashily the pull force plummet, when the product does not touch directly to the metal substrate. When designing the mounting, avoid additional spacers.

This section presents the approximate weight limit sufficient to start the sliding of the magnet down along a upright steel plate (considering typical friction). The holding force is relative to the distance between the magnet and the metal.

Table 3: Vertical assembly (shearing) - vertical pull

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

When hanging a element on a upright plane (e.g., a board), it will maintain barely approx. 20%-30% of nominal attraction strength. Gravitational force as well as a weak degree of grip mean that magnets slip easier than they pull off. Planning a hanger? Consider that the shear force is much weaker than the perpendicular breakaway force. On a painted metal, the element will give way down under a noticeably lighter cargo. Utilizing a rubberized coating can drastically increase the grip.

A too thin steel is unable to take in the entire magnetic field, which squanders power of the magnet. Should you mount a strong magnet to a thin surface, the flux will penetrate right through and the holding will be smaller. To squeeze the maximum of this magnet's potential, you require a sufficiently solid piece of metal. The material oversaturation means that on thin elements (e.g., appliance housings), the magnet shows lower pull force. We recommend selecting the steel cross-section based on the following data.

Standard neodymium magnets change their properties strength above the temperature limit. Protect against heat – high temperature can irreversibly demagnetize this product. With every degree above norm, the magnet's force momentarily drops. Avoid using this product close to heaters exceeding its working range. Exceeding the critical threshold will result in irreversible degradation of magnetic properties.

*Engineering note: Heat tolerance depends not only on the material grade, as well as the dimension ratios. Flat magnets (low permeance coefficient) may lose charge permanently sooner than long magnets. Red status in the table points to permanent field degradation for this specific geometry.

Two magnets interact from a much further distance than a neodymium and metal setup. Such a system of magnet-to-magnet generates a stronger field and a wider radius of performance. Designing a strong closure? Use a pair of magnets instead of one magnet and a striker plate. Be careful that when bringing together two magnets, the impact force is huge. The repulsion force is slightly lower than the connection force, but still significant.
*Flux density between like poles drops to ~0 Gs in the exact middle of the gap (caused by magnetic field nullification).
Attention: Estimates apply to sliding force of two matching magnets (friction coefficient ~0.15 for Ni-Ni coating).

A strong magnetic field poses a large risk to electronic devices and medical implants. These NdFeB products produce a field that disrupts operation of digital equipment. Remember: the invisible magnetic field acts through matter and housings. Exceptional care must be exercised by people with cochlear implants and insulin pumps. Influence will be felt by: mechanical watches, car keys, membranes, and displays. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Magnetic elements are delicate – a violent impact against metal can result in shattering. Watch the impact speed – a neodymium left loose turns into a projectile. Impact energy can trigger coating fragments or injury to fingers. Hold the magnet firmly during installation so it doesn't hit violently against the metal. A collision at high speed ends with a crack of the neodymium. Wear eye protection when handling with powerful specimens.

Corrosion warning: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

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 surface, the magnet holds merely approx. 20-30% of its nominal pull.

2. Plate thickness effect

*Thin metal sheet (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

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.

This product is an extremely strong magnet in the shape of a plate made of NdFeB material, which, with dimensions of 40x18x10 mm and a weight of 54 g, guarantees premium class connection. As a block magnet with high power (approx. 23.81 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.

Separating strong flat magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. To separate the MPL 40x18x10 SH / N38 model, firmly slide one magnet over the edge of the other until the attraction force decreases. We recommend extreme caution, 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 40x18x10 SH / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. Thanks to the flat surface and high force (approx. 23.81 kg), they are ideal as closers in furniture making and mounting elements in automation. 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 40x18x10 SH / 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. In practice, this means that this magnet has the greatest attraction force on its main planes (40x18 mm), which is ideal for flat mounting. This is the most popular configuration for block magnets used in separators and holders.

The presented product is a neodymium magnet with precisely defined parameters: 40 mm (length), 18 mm (width), and 10 mm (thickness). The key parameter here is the lifting capacity amounting to approximately 23.81 kg (force ~233.58 N), which, with such a flat shape, proves the high power of the material. The product meets the standards for N38 grade magnets.

Advantages and disadvantages of neodymium magnets.

Pros

Besides their stability, neodymium magnets are valued for these benefits:

They virtually do not lose power, because even after 10 years the performance loss is only ~1% (in laboratory conditions),
They show high resistance to demagnetization induced by external magnetic fields,
By using a smooth layer of nickel, the element gains an professional look,
Neodymium magnets deliver maximum magnetic induction on a small surface, which allows for strong attraction,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
Thanks to versatility in forming and the ability to modify to complex applications,
Wide application in advanced technology sectors – they find application in data components, electric motors, precision medical tools, also modern systems.
Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which makes them useful in compact constructions

Limitations

Cons of neodymium magnets and proposals for their use:

They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only shields the magnet but also improves its resistance to damage
Neodymium magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
We recommend cover - magnetic mechanism, due to difficulties in realizing threads inside the magnet and complex shapes.
Potential hazard resulting from small fragments of magnets can be dangerous, if swallowed, which gains importance in the context of child safety. Additionally, small elements of these products can disrupt the diagnostic process medical after entering the body.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities

Holding force characteristics

Breakaway strength of the magnet in ideal conditions – what it depends on?

The load parameter shown concerns the peak performance, measured under ideal test conditions, namely:

using a plate made of mild steel, acting as a circuit closing element
with a cross-section of at least 10 mm
with a plane perfectly flat
under conditions of gap-free contact (metal-to-metal)
during detachment in a direction perpendicular to the plane
at temperature room level

Impact of factors on magnetic holding capacity in practice

Effective lifting capacity is influenced by working environment parameters, such as (from most important):

Clearance – existence of foreign body (paint, tape, air) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
Force direction – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the maximum value.
Plate thickness – too thin steel does not close the flux, causing part of the flux to be wasted to the other side.
Plate material – mild steel attracts best. Higher carbon content decrease magnetic permeability and holding force.
Surface quality – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Roughness acts like micro-gaps.
Temperature – heating the magnet causes a temporary drop of force. Check the thermal limit for a given model.

Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under attempts to slide the magnet the holding force is lower. Moreover, even a minimal clearance between the magnet and the plate reduces the lifting capacity.

Safe handling of NdFeB magnets

Finger safety

Large magnets can crush fingers in a fraction of a second. Never put your hand betwixt two attracting surfaces.

Powerful field

Be careful. Rare earth magnets act from a distance and connect with massive power, often faster than you can move away.

Fire risk

Powder generated during grinding of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.

Cards and drives

Very strong magnetic fields can corrupt files on credit cards, HDDs, and storage devices. Keep a distance of at least 10 cm.

Danger to the youngest

NdFeB magnets are not toys. Swallowing a few magnets can lead to them pinching intestinal walls, which constitutes a critical condition and requires immediate surgery.

Skin irritation risks

Medical facts indicate that nickel (standard magnet coating) is a potent allergen. If you have an allergy, refrain from touching magnets with bare hands and select coated magnets.

Do not overheat magnets

Monitor thermal conditions. Heating the magnet to high heat will ruin its properties and strength.

Health Danger

Medical warning: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have electronic implants.

Compass and GPS

A powerful magnetic field disrupts the functioning of magnetometers in phones and navigation systems. Keep magnets close to a device to avoid breaking the sensors.

Fragile material

Protect your eyes. Magnets can fracture upon violent connection, launching shards into the air. Wear goggles.
