Pulling power decreases drastically with every subsequent millimeter of distance. Keep in mind that even a microscopic distance (e.g., dirt, paint, rust) noticeably diminishes the holding power. Magnets operate strongest during direct contact; air break nullifies the power. Observe how quickly the parameters fall, when the product does not touch flatly to the steel surface. When calculating the mounting, avoid additional spacers.

The table below defines the approximate weight limit sufficient to cause the slippage of the magnet down on a upright metal surface (considering standard friction). This parameter is relative to the distance between the magnet and the metal.

When mounting a magnet on a vertical plane (e.g., a fridge), it will maintain only approx. 20%-30% of its maximum pull force. Gravity as well as a weak degree of grip cause that products move down faster than they detach. Designing a hanger? Consider that the sliding force is noticeably lower than the maximum static pull force. On a painted metal, the magnet will give way down under a noticeably lighter cargo. Using a rubber coating can drastically improve the result.

A too thin steel is unable to conduct the full magnetic flux, which wastes potential of the magnet. Should you mount a strong magnet to a too thin substrate, the field will penetrate right through and the pull force will drop sharply. To squeeze 100% of this neodymium's potential, you require a sufficiently solid backing of steel. The material oversaturation means that on sheet metal structures (e.g., car bodies), the magnet holds weaker. We suggest choosing the steel cross-section according to the table below.

Ordinary NdFeB products change their properties parameters past the thermal threshold. Watch out for overheating – excessive heat can irreversibly damage this product. As the temperature rises, the neodymium's force momentarily drops. Refrain from using this magnet close to ovens higher than its safe range. Too high temperature will lead to permanent loss of magnetic properties.

*Important note: Thermal stability is determined by both grade, and the Permeance Coefficient Pc. Flat magnets (low permeance coefficient) risk losing magnetic properties under lower heat stress compared to rod magnets. Red status in the table signals permanent field degradation for this specific geometry.

Two magnetic products attract each other from a wider radius than a magnet and sheet setup. The setup of magnet-to-magnet creates a more powerful interaction and a wider radius of performance. Want to build a solid fastener? Utilize two neodymiums instead of a neodymium and a striker plate. Be careful that when bringing together two magnets, the pinch force is extreme. The levitation is marginally weaker than the attraction, but still impressive.
*Field value between like poles is approximately ~0 Gs in the exact middle between the magnets (due to field cancellation).
Important: Results show sliding force of a pair of same magnets (friction coefficient ~0.15 for Ni-Ni plating).

Powerful magnet radiation is a real danger to electronic devices and medical implants. These neodymiums produce a flux that destroys function of sensitive medical devices. Be aware: the invisible magnetic field acts through matter and plastic. Exceptional care must be exercised by people with hearing aids and drug dispensers. The risk also applies to: automatic timepieces, remotes, membranes, and displays. Do not bring the product near payment cards, hard drives, or sensitive navigation tools.

Neodymium magnets are prone to chipping – a strong collision with metal causes immediate chipping. Watch the impact speed – a magnet released freely speeds with massive force. Impact energy can cause material chips or painful pinches to fingers. Hold the magnet firmly during bringing near metal so it doesn't hit violently against the steel surface. A collision at high speed means shattering of the neodymium. 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.

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. Vertical hold

*Warning: On a vertical wall, the magnet holds only a fraction of its perpendicular strength.

2. Efficiency vs thickness

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

3. Heat tolerance

*For N38 grade, 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) = 0.14

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.

Model MPL 25x15x2 / N38 features a flat shape and industrial pulling force, making it a perfect solution for building separators and machines. As a block magnet with high power (approx. 1.89 kg), this product is available off-the-shelf from our warehouse in Poland. Additionally, its Ni-Cu-Ni coating protects it against corrosion in standard operating conditions, giving it an aesthetic appearance.

The key to success is sliding 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 25x15x2 / 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. Never use metal tools for prying, as the brittle NdFeB material may chip and damage your eyes.

Plate magnets MPL 25x15x2 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. They work great as fasteners 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 25x15x2 / N38 model is magnetized axially (dimension 2 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 (25x15 mm), which is ideal for flat mounting. This is the most popular configuration for block magnets used in separators and holders.

This model is characterized by dimensions 25x15x2 mm, which, at a weight of 5.63 g, makes it an element with high energy density. It is a magnetic block with dimensions 25x15x2 mm and a self-weight of 5.63 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages as well as disadvantages of Nd₂Fe₁₄B magnets.

Strengths

Besides their exceptional pulling force, neodymium magnets offer the following advantages:

They do not lose magnetism, even over nearly ten years – the reduction in lifting capacity is only ~1% (based on measurements),
Neodymium magnets prove to be remarkably resistant to magnetic field loss caused by external field sources,
By using a shiny coating of gold, the element gains an aesthetic look,
Neodymium magnets ensure maximum magnetic induction on a their surface, which allows for strong attraction,
Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
Possibility of detailed forming and modifying to defined needs,
Wide application in high-tech industry – they find application in mass storage devices, electromotive mechanisms, diagnostic systems, as well as other advanced devices.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Disadvantages

Cons of neodymium magnets: tips and applications.

They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
When exposed to high temperature, neodymium magnets suffer a drop in strength. 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
Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
We recommend a housing - magnetic holder, due to difficulties in realizing nuts inside the magnet and complicated forms.
Possible danger resulting from small fragments of magnets can be dangerous, if swallowed, which gains importance in the context of child health protection. It is also worth noting that small elements of these magnets are able to be problematic in diagnostics medical after entering the body.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Lifting parameters

Maximum lifting force for a neodymium magnet – what affects it?

The lifting capacity listed is a result of laboratory testing performed under standard conditions:

using a base made of high-permeability steel, acting as a ideal flux conductor
possessing a thickness of min. 10 mm to ensure full flux closure
with an polished contact surface
with total lack of distance (without paint)
under perpendicular application of breakaway force (90-degree angle)
at standard ambient temperature

Lifting capacity in real conditions – factors

Effective lifting capacity impacted by specific conditions, such as (from priority):

Distance (betwixt the magnet and the metal), since even a very small clearance (e.g. 0.5 mm) leads to a drastic drop in force by up to 50% (this also applies to paint, corrosion or debris).
Force direction – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the maximum value.
Steel thickness – too thin steel causes magnetic saturation, causing part of the power to be wasted into the air.
Metal type – not every steel reacts the same. Alloy additives worsen the attraction effect.
Surface quality – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Roughness creates an air distance.
Temperature influence – hot environment weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under shearing force the load capacity is reduced by as much as 75%. Moreover, even a slight gap between the magnet’s surface and the plate reduces the load capacity.

Warnings

Crushing force

Pinching hazard: The attraction force is so great that it can cause blood blisters, pinching, and even bone fractures. Protective gloves are recommended.

Phone sensors

A strong magnetic field disrupts the operation of compasses in smartphones and GPS navigation. Maintain magnets close to a device to avoid damaging the sensors.

Thermal limits

Control the heat. Heating the magnet to high heat will destroy its properties and pulling force.

Shattering risk

Beware of splinters. Magnets can explode upon uncontrolled impact, launching shards into the air. Eye protection is mandatory.

Warning for allergy sufferers

A percentage of the population experience a contact allergy to nickel, which is the standard coating for neodymium magnets. Prolonged contact may cause dermatitis. We strongly advise use protective gloves.

Danger to pacemakers

Individuals with a heart stimulator should keep an safe separation from magnets. The magnetic field can stop the functioning of the life-saving device.

Safe distance

Do not bring magnets close to a purse, computer, or TV. The magnetic field can permanently damage these devices and wipe information from cards.

Product not for children

NdFeB magnets are not suitable for play. Accidental ingestion of several magnets can lead to them pinching intestinal walls, which constitutes a severe health hazard and necessitates immediate surgery.

Safe operation

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

Combustion hazard

Drilling and cutting of neodymium magnets poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
