Grip strength drops sharply with every subsequent millimeter of gap. Remember that every additional insulation layer (e.g., dirt, varnish, dust) noticeably reduces the pull force. Neodymiums work most effectively in perfect adhesion; gap drastically cuts the power. Analyze how rapidly the pull force drop, when the magnet does not touch tightly to the metal substrate. When calculating the mounting, avoid additional spacers.

When mounting a holder on a upright surface (e.g., a car body), it will maintain only about 1/5 of nominal attraction strength. Gravitational force and a low friction coefficient cause that magnets slip easier than they pull off. Want to create a wall mount? 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 load. Utilizing a rubberized coating can significantly raise the stability.

A too thin steel cannot conduct the entire magnetic field, which wastes potential of the holder. Should you mount a strong magnet to a too thin substrate, the field will penetrate right through and the attraction force will be weaker. To squeeze the maximum of this magnet's potential, you need a suitably thick piece of steel. The saturation effect causes that on delicate walls (e.g., car bodies), the product shows lower pull force. We suggest choosing the steel thickness from these parameters.

Standard neodymium magnets change their properties strength above the temperature limit. Watch out for overheating – excessive heat can permanently damage this magnet. With increasing heat, the neodymium's capacity momentarily drops. Refrain from using this magnet near heat sources exceeding its working range. Exceeding the critical threshold will result in destruction of magnetism.
*Technical advisory: Heat tolerance is determined by both grade, but also on the magnet's shape. Low-profile magnets (pancake types) may lose charge permanently at lower temperatures than long magnets. Warning indicator in the table indicates a risk of irreversible loss for this particular item.

Two strong neodymiums interact from a much further distance than a magnet and steel combination. The setup of two magnets creates a more powerful interaction and a wider radius of operation. Planning to create a strong closure? Use a pair of magnets instead of a neodymium and a steel. Remember that when bringing together two magnets, the impact force is massive. The repulsion force is slightly lower than the connection force, but still significant.
*Field value for N-N configuration is approximately ~0 Gs at the midpoint between the magnets (resulting from vector opposition).
Attention: Figures show sliding force of dual identical magnets (friction ~0.15 for Ni-Ni coating).

Powerful magnet radiation is a serious hazard to IT equipment and pacemakers. These magnets produce a flux that disrupts operation of sensitive medical devices. Notice: the unseen radiation acts through matter and housings. Increased vigilance must be exercised by people with hearing aids and drug dispensers. Also at risk are: mechanical watches, remotes, membranes, and screens. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

NdFeB products are delicate – a violent impact against metal causes immediate chipping. Pay attention to connection velocity – a magnet released freely becomes dangerous. Striking energy can cause material chips or dangerous crushing to fingers. Always hold the magnet during mounting so it doesn't hit violently against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Wear safety glasses when playing with powerful specimens.

1. Wall mount (shear)

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

2. Steel thickness impact

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

3. Temperature resistance

*For standard magnets, the critical limit is 80°C.

4. Demagnetization curve and operating point (B-H)

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.38

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 Pc (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 Pc 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 a very powerful magnet in the shape of a plate made of NdFeB material, which, with dimensions of 25x10x5 mm and a weight of 9.38 g, guarantees premium class connection. As a block magnet with high power (approx. 7.49 kg), this product is available off-the-shelf from our warehouse in Poland. Additionally, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, giving it an aesthetic appearance.
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 25x10x5 / 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.
They constitute a key element in the production of wind generators and material handling systems. Thanks to the flat surface and high force (approx. 7.49 kg), they are ideal as hidden locks in furniture making and mounting elements in automation. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.
For mounting flat magnets MPL 25x10x5 / 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. Remember to clean and degrease the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.
Standardly, the MPL 25x10x5 / N38 model is magnetized axially (dimension 5 mm), which means that the N and S poles are located on its largest, flat surfaces. 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), 10 mm (width), and 5 mm (thickness). The key parameter here is the holding force amounting to approximately 7.49 kg (force ~73.45 N), which, with such a flat shape, proves the high grade of the material. The product meets the standards for N38 grade magnets.

Strengths as well as weaknesses of Nd2Fe14B magnets.

Strengths

In addition to their pulling strength, neodymium magnets provide the following advantages:
  • They do not lose magnetism, even during approximately 10 years – the reduction in strength is only ~1% (theoretically),
  • They do not lose their magnetic properties even under strong external field,
  • By covering with a smooth coating of gold, the element has an elegant look,
  • The surface of neodymium magnets generates a concentrated magnetic field – this is a key feature,
  • Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
  • Possibility of exact shaping and optimizing to complex needs,
  • Universal use in electronics industry – they find application in mass storage devices, brushless drives, diagnostic systems, as well as industrial machines.
  • Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Cons

Problematic aspects 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 in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
  • When exposed to high temperature, neodymium magnets experience a drop in power. 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
  • 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 casing - magnetic mechanism, due to difficulties in producing threads inside the magnet and complicated shapes.
  • Possible danger to health – tiny shards of magnets can be dangerous, in case of ingestion, which gains importance in the context of child health protection. It is also worth noting that small components of these magnets can complicate diagnosis medical in case of swallowing.
  • Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Pull force analysis

Highest magnetic holding force – what contributes to it?

Information about lifting capacity was determined for the most favorable conditions, taking into account:
  • on a block made of mild steel, effectively closing the magnetic field
  • with a thickness minimum 10 mm
  • with an polished touching surface
  • without any air gap between the magnet and steel
  • under perpendicular application of breakaway force (90-degree angle)
  • at temperature room level

Determinants of lifting force in real conditions

In practice, the actual lifting capacity depends on several key aspects, ranked from crucial:
  • Distance – the presence of foreign body (paint, dirt, air) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
  • Loading method – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet exhibits much less (often approx. 20-30% of nominal force).
  • Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
  • Steel type – mild steel attracts best. Alloy steels lower magnetic permeability and lifting capacity.
  • Surface condition – smooth surfaces ensure maximum contact, which improves force. Rough surfaces reduce efficiency.
  • Thermal conditions – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).

Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under shearing force the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.

Precautions when working with NdFeB magnets
Magnet fragility

Neodymium magnets are ceramic materials, which means they are prone to chipping. Collision of two magnets will cause them shattering into small pieces.

GPS and phone interference

Navigation devices and mobile phones are highly sensitive to magnetism. Direct contact with a powerful NdFeB magnet can decalibrate the sensors in your phone.

Sensitization to coating

Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If redness occurs, immediately stop working with magnets and wear gloves.

Do not give to children

Product intended for adults. Tiny parts pose a choking risk, leading to serious injuries. Store out of reach of kids and pets.

Data carriers

Equipment safety: Strong magnets can ruin data carriers and delicate electronics (heart implants, hearing aids, timepieces).

Safe operation

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

Heat warning

Regular neodymium magnets (N-type) lose magnetization when the temperature exceeds 80°C. This process is irreversible.

Warning for heart patients

Warning for patients: Powerful magnets disrupt medical devices. Maintain at least 30 cm distance or request help to work with the magnets.

Fire warning

Machining of NdFeB material poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.

Serious injuries

Mind your fingers. Two large magnets will join instantly with a force of several hundred kilograms, crushing anything in their path. Be careful!
