Grip strength weakens significantly with every subsequent millimeter of gap. Note that even the smallest gap (e.g., dirt, varnish, dust) noticeably reduces the pull force. Neodymiums operate strongest during direct contact; air break kills the power. Analyze how rapidly the load capacity fall, when the product does not touch flatly to the metal substrate. When designing the arrangement, discard additional spacers.

When placing a magnet on a upright surface (e.g., a car body), it will only hold only approx. 20%-30% of its maximum pull force. Gravity and a low friction coefficient cause that holders slide down faster than they detach. Want to create a hanger? Consider that the sliding force is much weaker than the maximum static pull force. On a painted metal, the holder will give way down under a noticeably lighter cargo. Using a rubber pad can drastically raise the stability.

A too thin steel is not enough to take in the entire magnetic field, which squanders power of the magnet. Should you attach a powerful product to a too thin substrate, the magnetism will penetrate right through and the pull force will drop sharply. To utilize full efficiency of this magnet's power, you need a suitably thick element of steel. The saturation effect means that on thin elements (e.g., car bodies), the holder shows lower pull force. We suggest choosing the steel dimension from these parameters.

Classic neodymiums irreversibly lose power above the temperature limit. Protect against heat – high temperature can irreversibly damage this product. With increasing heat, the neodymium's power briefly drops. Refrain from using this product close to heaters higher than its working range. Too high temperature will result in permanent loss of magnetic properties.
*Engineering note: Temperature resistance depends not only on the material grade, and the Permeance Coefficient Pc. Thin magnets (pancake types) risk losing magnetic properties sooner than long magnets. The danger warning in the table signals permanent field degradation for this specific geometry.

Two magnetic products interact from a significantly greater distance than a magnet and sheet setup. The setup of two magnets creates a more powerful interaction and a wider radius of operation. Designing a powerful holder? Apply two magnets instead of one magnet and a steel. Be careful that when attracting two neodymiums, the collision energy is huge. The repulsion force is a bit weaker than the attraction, but still impressive.
*Flux density between like poles reaches ~0 Gs in the exact middle between the magnets (caused by magnetic field nullification).
Important: Estimates show sliding force of two identical neodymium magnets (friction ~0.15 for Ni-Ni coating).

Powerful magnet radiation is a large risk to electronic devices as well as medical implants. These NdFeB products produce a field that disrupts operation of sensitive medical devices. Remember: the invisible magnetic field acts through matter and plastic. Increased vigilance must be taken by people with hearing aids and drug dispensers. The risk also applies to: mechanical watches, car keys, membranes, and screens. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

Neodymium magnets are delicate – a strong collision with metal can result in shattering. Watch the impact speed – a magnet released freely becomes dangerous. Striking energy can trigger coating fragments or dangerous crushing to fingers. Be sure to control the product during bringing near metal so it doesn't slam with momentum against the metal. A collision at high speed almost guarantees destruction of the neodymium. Wear safety glasses when working with large magnets.

Corrosion warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.
Water displaces steel, making heavy objects slightly lighter. Buoyancy helps in lifting finds.
1. Sliding resistance

*Note: On a vertical wall, the magnet retains only approx. 20-30% of its nominal pull.

2. Efficiency vs thickness

*Thin metal sheet (e.g. 0.5mm PC case) severely weakens the holding force.

3. Heat tolerance

*For N38 material, the safety limit is 80°C.

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.36

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.

Component MPL 45x25x10 / N38 features a low profile and professional pulling force, making it an ideal solution for building separators and machines. As a block magnet with high power (approx. 28.48 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. Watch your fingers! Magnets with a force of 28.48 kg can pinch very hard and cause hematomas. Using a screwdriver risks destroying the coating and permanently cracking the magnet.
Plate magnets MPL 45x25x10 / N38 are the foundation for many industrial devices, such as filters catching filings and linear motors. Thanks to the flat surface and high force (approx. 28.48 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.
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. 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 (45x25 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: 45 mm (length), 25 mm (width), and 10 mm (thickness). The key parameter here is the lifting capacity amounting to approximately 28.48 kg (force ~279.40 N), which, with such a flat shape, proves the high power of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages and disadvantages of Nd2Fe14B magnets.

Strengths

In addition to their magnetic capacity, neodymium magnets provide the following advantages:
  • Their magnetic field is durable, and after approximately 10 years it decreases only by ~1% (according to research),
  • They do not lose their magnetic properties even under strong external field,
  • By using a shiny layer of silver, the element acquires an elegant look,
  • Magnetic induction on the top side of the magnet is impressive,
  • 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...
  • In view of the potential of flexible molding and customization to specialized solutions, NdFeB magnets can be created in a variety of geometric configurations, which amplifies use scope,
  • Wide application in electronics industry – they are used in computer drives, brushless drives, medical equipment, as well as technologically advanced constructions.
  • Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Weaknesses

Drawbacks and weaknesses of neodymium magnets: application proposals
  • To avoid cracks under impact, we suggest using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
  • Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
  • They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
  • We recommend a housing - magnetic holder, due to difficulties in producing threads inside the magnet and complicated shapes.
  • Health risk resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child health protection. It is also worth noting that small elements of these products can be problematic in diagnostics medical in case of swallowing.
  • Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Lifting parameters

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

The lifting capacity listed is a measurement result executed under the following configuration:
  • on a block made of structural steel, optimally conducting the magnetic flux
  • with a thickness of at least 10 mm
  • characterized by even structure
  • with zero gap (no coatings)
  • during pulling in a direction perpendicular to the plane
  • in temp. approx. 20°C

Practical aspects of lifting capacity – factors

Please note that the application force will differ influenced by elements below, starting with the most relevant:
  • Distance – the presence of foreign body (paint, dirt, air) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
  • Angle of force application – maximum parameter is obtained only during perpendicular pulling. The shear force of the magnet along the plate is usually several times lower (approx. 1/5 of the lifting capacity).
  • Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
  • Material type – ideal substrate is high-permeability steel. Cast iron may generate lower lifting capacity.
  • Surface quality – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
  • Thermal environment – temperature increase causes a temporary drop of induction. Check the maximum operating temperature for a given model.

Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate decreases the load capacity.

It is widely known that the nickel plating (the usual finish) is a potent allergen. If your skin reacts to metals, refrain from touching magnets with bare hands and select encased magnets.

Risk of cracking

Watch out for shards. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. We recommend safety glasses.

Danger to the youngest

Absolutely keep magnets out of reach of children. Ingestion danger is high, and the effects of magnets connecting inside the body are tragic.

Warning for heart patients

Individuals with a ICD have to maintain an safe separation from magnets. The magnetism can stop the functioning of the implant.

Conscious usage

Exercise caution. Rare earth magnets act from a long distance and connect with huge force, often quicker than you can react.

Keep away from computers

Data protection: Strong magnets can ruin payment cards and sensitive devices (heart implants, hearing aids, mechanical watches).

Crushing force

Pinching hazard: The attraction force is so great that it can result in hematomas, pinching, and even bone fractures. Use thick gloves.

Heat warning

Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and pulling force.

Threat to navigation

Note: neodymium magnets generate a field that interferes with precision electronics. Keep a separation from your mobile, tablet, and GPS.

Fire risk

Fire warning: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this risks ignition.
