Grip strength weakens drastically with every subsequent millimeter of gap. Remember that every additional insulation layer (e.g., dirt, paint, dust) strongly weakens the grip. Magnets work optimally in perfect adhesion; gap weakens the power. Notice how quickly the parameters plummet, when the product does not adhere directly to the steel surface. When planning the mounting, eliminate additional spacers.

This section shows the theoretical force sufficient to initiate the downward movement of the magnet vertically against a vertical steel wall (assuming standard friction coefficient). This parameter depends on the air gap between the magnet and the surface.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces
MPL 40x18x10 / 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 magnet on a upright plane (e.g., a fridge), it will maintain barely approx. 20%-30% of its nominal power. Gravitational force and a weak degree of grip mean that products slip easier than they detach. Designing a hanger? Remember that the sliding force is significantly lower than the perpendicular breakaway force. On a smooth steel, the holder will give way down under a much lighter weight. Using a rubber pad can effectively raise the stability.

12 mm	100%	23.81 kg / 52.49 pounds 23810.0 g / 233.6 N

A thin metal plate is not enough to take in the full magnetic flux, which weakens actual performance of the holder. Should you mount a strong magnet to a weak sheet, the field will penetrate right through and the attraction force will be weaker. To squeeze full efficiency of this magnet's potential, you need a suitably thick backing of metal. The saturation phenomenon means that on thin elements (e.g., car bodies), the product holds weaker. We advise picking the steel cross-section from these parameters.

Classic neodymiums change their properties power after exceeding the maximum temperature. Watch out for overheating – excessive heat can permanently damage this product. With every degree above norm, the neodymium's capacity momentarily lowers. Avoid using this product close to ovens higher than its safe range. Exceeding the critical threshold will lead to destruction of magnetism.

*Technical advisory: Thermal stability is determined by both grade, and the Permeance Coefficient Pc. Flat magnets (low permeance coefficient) are more susceptible to demagnetization sooner than taller cylinders. Red status in the table signals permanent field degradation for this specific geometry.

Two magnets interact from a significantly greater distance than a neodymium and metal setup. Such a system of magnet-to-magnet creates a more powerful interaction and a larger range of action. Want to build a strong closure? Apply two magnets instead of one magnet and a steel. Remember that when attracting two neodymiums, the impact force is huge. The repulsion force is a bit weaker than the connection force, but still significant.
*Field value in repulsion mode drops to ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
Note: Estimates apply to sliding force of a pair of matching neodymium magnets (friction ~0.15 for Ni-Ni plating).

A strong magnetic field is a large risk to electronics and medical implants. These magnets produce a field that destroys function of sensitive medical devices. Notice: the unseen radiation acts through matter and plastic. 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 bring the product near payment cards, hard drives, or precise measuring instruments.

Neodymium magnets are delicate – a strong collision with metal causes immediate chipping. Control the attraction moment – a neodymium left loose speeds with massive force. Striking energy can destroy the magnet or painful pinches to fingers. Hold the magnet firmly during installation so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h ends with a crack of the magnet. Use safety goggles when handling with powerful specimens.

Warning: 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. Sliding resistance

*Note: On a vertical surface, the magnet holds just a fraction of its nominal pull.

2. Efficiency vs thickness

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

3. Thermal stability

*For N38 grade, 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 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 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. Additionally, its Ni-Cu-Ni coating protects it against corrosion in standard operating conditions, giving it an aesthetic appearance.

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 40x18x10 / 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. Never use metal tools for prying, as the brittle NdFeB material may chip and damage your eyes.

Plate magnets MPL 40x18x10 / 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.

For mounting flat magnets MPL 40x18x10 / N38, it is best to use two-component adhesives (e.g., UHU Endfest, Distal), which ensure a durable bond with metal or plastic. Double-sided tape cushions vibrations, which is an advantage when mounting in moving elements. Remember to roughen and wash the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

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). It is a magnetic block with dimensions 40x18x10 mm and a self-weight of 54 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 neodymium magnets.

Advantages

Apart from their strong magnetic energy, neodymium magnets have these key benefits:

They retain attractive force for almost ten years – the loss is just ~1% (in theory),
They have excellent resistance to magnetic field loss as a result of external fields,
By covering with a reflective coating of nickel, the element acquires an modern look,
Magnets exhibit excellent magnetic induction on the outer side,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
Possibility of individual shaping as well as adjusting to atypical requirements,
Versatile presence in advanced technology sectors – they are used in hard drives, electric motors, advanced medical instruments, and other advanced devices.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which makes them useful in compact constructions

Cons

Drawbacks and weaknesses of neodymium magnets and proposals for their use:

They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
We recommend cover - magnetic holder, due to difficulties in producing threads inside the magnet and complex forms.
Potential hazard to health – tiny shards of magnets pose a threat, in case of ingestion, which becomes key in the context of child safety. Additionally, small components of these products can complicate diagnosis medical after entering the body.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Holding force characteristics

Magnetic strength at its maximum – what it depends on?

The lifting capacity listed is a measurement result performed under standard conditions:

using a plate made of mild steel, functioning as a circuit closing element
whose transverse dimension is min. 10 mm
characterized by even structure
with total lack of distance (without impurities)
during pulling in a direction perpendicular to the mounting surface
at room temperature

Magnet lifting force in use – key factors

It is worth knowing that the application force will differ depending on elements below, in order of importance:

Clearance – the presence of foreign body (paint, dirt, air) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
Force direction – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
Plate thickness – insufficiently thick plate causes magnetic saturation, causing part of the power to be wasted into the air.
Plate material – mild steel attracts best. Alloy admixtures lower magnetic properties and holding force.
Base smoothness – the more even the surface, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
Temperature – heating the magnet causes a temporary drop of induction. Check the maximum operating temperature for a given model.

Lifting capacity testing was conducted on a smooth plate of optimal thickness, under perpendicular forces, whereas under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.

Precautions when working with neodymium magnets

Skin irritation risks

Certain individuals have a sensitization to Ni, which is the common plating for neodymium magnets. Prolonged contact might lead to a rash. It is best to use safety gloves.

Demagnetization risk

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

Fire warning

Powder produced during grinding of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.

Hand protection

Watch your fingers. Two powerful magnets will snap together instantly with a force of massive weight, destroying everything in their path. Be careful!

Magnet fragility

Despite metallic appearance, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.

Danger to the youngest

Adult use only. Tiny parts pose a choking risk, leading to intestinal necrosis. Keep out of reach of children and animals.

Keep away from computers

Avoid bringing magnets near a purse, laptop, or TV. The magnetic field can destroy these devices and erase data from cards.

Health Danger

Warning for patients: Powerful magnets disrupt electronics. Maintain minimum 30 cm distance or request help to handle the magnets.

Phone sensors

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

Handling rules
