Pulling power decreases sharply with every subsequent millimeter of gap. Note that even the smallest gap (e.g., dirt, varnish, veneer) strongly reduces the pull force. Magnets operate strongest during direct contact; distance drastically cuts the force. Observe how quickly the pull force fall, when the magnet does not adhere directly to the metal substrate. When planning the mounting, discard redundant distances.

The following data defines the approximate shear load necessary to cause the sliding of the magnet vertically on a vertical steel plate (considering typical friction coefficient). This value depends on the separation distance between the magnet and the metal.

When mounting a holder on a upright plane (e.g., a car body), it will only hold barely about 1/5 of nominal attraction strength. Gravitational force as well as a weak degree of grip influence the fact that magnets slip easier than they pull off. Want to create a wall mount? Note that the sliding force is noticeably lower than the perpendicular breakaway force. On a slippery surface, the magnet will give way down under a much lighter load. Application of an anti-slip pad can effectively increase the grip.

A too thin steel cannot focus the entire magnetic field, which squanders power of the magnet. Should you mount a strong magnet to a weak sheet, the magnetism will pass right through and the attraction force will be weaker. To utilize full efficiency of this neodymium's potential, you require a sufficiently solid backing of steel. The saturation effect causes that on delicate walls (e.g., car bodies), the holder shows lower pull force. We suggest choosing the steel cross-section according to the table below.

Ordinary NdFeB products irreversibly lose strength past the thermal threshold. Avoid high temperatures – excessive heat can irreversibly demagnetize this magnet. With increasing heat, the magnet's force briefly lowers. Do not use this product close to heaters exceeding its working range. Ignoring the limit will result in permanent loss of magnetism.

*Important note: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Thin magnets (low Pc) are more susceptible to demagnetization sooner than taller cylinders. Warning indicator in the table signals permanent field degradation for this specific geometry.

Two magnetic products attract each other from a significantly greater distance than a magnet and sheet combination. The connection of magnet-to-magnet creates a more powerful interaction and a further horizon of action. Planning to create a powerful holder? Use a pair of magnets instead of one magnet and a striker plate. Exercise caution that when attracting two neodymiums, the collision energy is massive. The repulsion force is a bit weaker than the attraction, but still impressive.
*The magnetic induction in repulsion mode reaches ~0 Gs in the exact middle between the magnets (caused by magnetic field nullification).
Note: Calculations apply to sliding force of dual identical neodymium magnets (friction ~0.15 for Ni-Ni coating).

Extremely neodym field poses a serious hazard to electronic devices and medical implants. These magnets produce a flux that prevents correct functioning of sensitive medical devices. Remember: the invisible magnetic field acts through matter and plastic. Special caution must be exercised by people with hearing aids and drug dispensers. Influence will be felt by: automatic timepieces, car keys, speakers, and screens. Do not bring the product near payment cards, HDD media, or precise measuring instruments.

NdFeB products are delicate – a collision with steel can result in shattering. Watch the impact speed – a magnet released freely turns into a projectile. Kinetic force can cause material chips or painful pinches to skin. Hold the magnet firmly during mounting so it doesn't slam with momentum against the metal. A collision at high speed ends with a crack of the neodymium. Wear eye protection when working with powerful specimens.

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. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Wall mount (shear)

*Warning: On a vertical wall, the magnet retains just a fraction of its nominal pull.

2. Steel saturation

*Thin metal sheet (e.g. computer case) significantly reduces 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) = 0.35

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 25x12.5x5 mm and a weight of 11.72 g, guarantees the highest quality connection. As a magnetic bar with high power (approx. 7.72 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 25x12.5x5 / 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 25x12.5x5 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. Thanks to the flat surface and high force (approx. 7.72 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 25x12.5x5 / N38, we recommend utilizing strong epoxy glues (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. 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. Thanks to this, it works best when "sticking" to sheet metal or another magnet with a large surface area. 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: 25 mm (length), 12.5 mm (width), and 5 mm (thickness). The key parameter here is the lifting capacity amounting to approximately 7.72 kg (force ~75.74 N), which, with such a compact shape, proves the high grade of the material. The product meets the standards for N38 grade magnets.

Pros as well as cons of Nd₂Fe₁₄B magnets.

Benefits

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

They do not lose strength, even over nearly 10 years – the drop in strength is only ~1% (theoretically),
Magnets effectively resist against loss of magnetization caused by ambient magnetic noise,
The use of an metallic layer of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
Magnets possess maximum magnetic induction on the active area,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
Possibility of accurate shaping and modifying to atypical applications,
Key role in electronics industry – they find application in mass storage devices, drive modules, precision medical tools, also other advanced devices.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Weaknesses

Cons 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 using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
Neodymium magnets lose their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
Limited possibility of creating threads in the magnet and complex forms - preferred is a housing - magnet mounting.
Possible danger related to microscopic parts of magnets can be dangerous, in case of ingestion, which gains importance in the aspect of protecting the youngest. It is also worth noting that small components of these magnets are able to be problematic in diagnostics medical when they are in the body.
Due to expensive raw materials, their price is higher than average,

Pull force analysis

Optimal lifting capacity of a neodymium magnet – what affects it?

Breakaway force was defined for the most favorable conditions, assuming:

on a block made of mild steel, effectively closing the magnetic field
possessing a massiveness of minimum 10 mm to ensure full flux closure
characterized by smoothness
with direct contact (no coatings)
under vertical force direction (90-degree angle)
at room temperature

What influences lifting capacity in practice

During everyday use, the actual lifting capacity results from several key aspects, listed from most significant:

Distance – the presence of foreign body (rust, tape, gap) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
Load vector – highest force is available only during pulling at a 90° angle. The shear force of the magnet along the surface is typically many times smaller (approx. 1/5 of the lifting capacity).
Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
Material type – ideal substrate is pure iron steel. Hardened steels may generate lower lifting capacity.
Base smoothness – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
Operating temperature – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under perpendicular forces, in contrast under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate lowers the lifting capacity.

H&S for magnets

Dust explosion hazard

Combustion risk: Neodymium dust is highly flammable. Do not process magnets without safety gear as this risks ignition.

Power loss in heat

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

Health Danger

Life threat: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.

Safe distance

Equipment safety: Neodymium magnets can ruin payment cards and sensitive devices (pacemakers, hearing aids, mechanical watches).

Fragile material

Protect your eyes. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. Wear goggles.

Swallowing risk

Adult use only. Tiny parts pose a choking risk, causing severe trauma. Store out of reach of children and animals.

Phone sensors

An intense magnetic field disrupts the operation of compasses in smartphones and GPS navigation. Do not bring magnets close to a device to avoid damaging the sensors.

Do not underestimate power

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

Nickel coating and allergies

Medical facts indicate that the nickel plating (standard magnet coating) is a strong allergen. If you have an allergy, prevent touching magnets with bare hands or choose coated magnets.

Crushing risk
