Grip strength weakens significantly with every mm of gap. Remember that even a microscopic distance (e.g., contamination, varnish, rust) significantly diminishes the holding power. Neodymiums hold most effectively at the point of direct contact; air break kills the power. See how quickly the parameters drop, when the magnet does not adhere flatly to the steel surface. When calculating the arrangement, eliminate redundant distances.

The following data presents the estimated holding capacity required to start the sliding of the magnet downwards on a upright metal surface (assuming typical friction coefficient). This value is relative to the separation distance between the magnet and the surface.

Table 3: Vertical assembly (sliding) - vertical pull
MPL 20x8x6 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	1.88 kg / 4.15 pounds 1881.0 g / 18.5 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.25 kg / 2.76 pounds 1254.0 g / 12.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.63 kg / 1.38 pounds 627.0 g / 6.2 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	3.14 kg / 6.91 pounds 3135.0 g / 30.8 N

When hanging a element on a upright plane (e.g., a board), it will maintain barely about 1/5 of nominal attraction strength. Gravitational force and a weak degree of grip influence the fact that products slide down easier than they pull off. Planning a vertical fastening? Consider that the shear force is significantly lower than the perpendicular breakaway force. On a slippery surface, the holder will slide down under a much lighter load. Using a rubber coating can drastically increase the grip.

12 mm	100%	6.27 kg / 13.82 pounds 6270.0 g / 61.5 N

A thin sheet is not enough to conduct the full magnetic flux, which weakens actual performance of the holder. If you attach a powerful product to a too thin substrate, the magnetism will penetrate right through and the attraction force will be weaker. To achieve full efficiency of this magnet's potential, you need a suitably thick piece of steel. The material oversaturation causes that on thin elements (e.g., thin profiles), the magnet works worse. We advise picking the steel thickness from these parameters.

Standard neodymium magnets lose strength above the temperature limit. Protect against heat – heat can permanently damage this magnet. With increasing heat, the neodymium's power momentarily drops. Do not use this product near heat sources exceeding its working range. Too high temperature will result in destruction of magnetic properties.

*Technical advisory: Thermal stability is determined by both grade, as well as the dimension ratios. Flat magnets (low Pc) may lose charge permanently under lower heat stress compared to rod magnets. Warning indicator in the table points to permanent field degradation for this specific geometry.

Two magnets interact from a wider radius than a neodymium and metal combination. The setup of magnet-to-magnet generates a stronger field and a further horizon of performance. Want to build a solid fastener? Use a pair of magnets instead of a neodymium and a steel. Remember that when connecting a pair of magnets, the impact force is huge. The repulsion force is marginally weaker than the connection force, but still impressive.
*Flux density in repulsion mode reaches ~0 Gs in the exact middle between the magnets (caused by magnetic field nullification).
Note: Estimates show friction force of dual same neodymium magnets (friction coefficient ~0.15 for Ni-Ni plating).

Extremely neodym field poses a serious hazard to electronics as well as medical implants. These NdFeB products produce a field that prevents correct functioning of digital equipment. Be aware: the unseen radiation acts through matter and housings. Increased vigilance must be exercised by people with hearing aids and insulin pumps. The risk also applies to: mechanical watches, car keys, speakers, and screens. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

Table 8: Dynamics (kinetic energy) - collision effects
MPL 20x8x6 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	30.06 km/h (8.35 m/s)	0.25 J
30 mm	51.55 km/h (14.32 m/s)	0.74 J
50 mm	66.55 km/h (18.49 m/s)	1.23 J
100 mm	94.11 km/h (26.14 m/s)	2.46 J

NdFeB products are very brittle – a violent impact against metal can result in shattering. Watch the impact speed – a neodymium left loose turns into a projectile. Striking energy can destroy the magnet or injury to skin. Hold the magnet firmly during mounting so it doesn't hit with great force against the steel surface. A contact at a velocity of dozens of km/h ends with a crack of the magnet. Use safety goggles when playing with large magnets.

Corrosion warning: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

In water, the magnet feels stronger thanks to Archimedes' principle. 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 surface, the magnet retains only ~20% of its max power.

2. Steel thickness impact

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

3. Power loss vs temp

*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) = 0.52

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 plate magnet made of NdFeB material, which, with dimensions of 20x8x6 mm and a weight of 7.2 g, guarantees premium class connection. As a magnetic bar with high power (approx. 6.27 kg), this product is available immediately from our warehouse in Poland. Furthermore, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, giving it an aesthetic appearance.

Separating block 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 6.27 kg can pinch very hard and cause hematomas. Never use metal tools for prying, as the brittle NdFeB material may chip and damage your eyes.

Plate magnets MPL 20x8x6 / 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. 6.27 kg), they are ideal as closers 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 20x8x6 / N38, we recommend utilizing 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. 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. 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: 20 mm (length), 8 mm (width), and 6 mm (thickness). The key parameter here is the holding force amounting to approximately 6.27 kg (force ~61.50 N), which, with such a flat shape, proves the high grade of the material. The product meets the standards for N38 grade magnets.

Pros as well as cons of rare earth magnets.

Strengths

Apart from their consistent holding force, neodymium magnets have these key benefits:

They retain attractive force for nearly 10 years – the loss is just ~1% (based on simulations),
Neodymium magnets prove to be remarkably resistant to loss of magnetic properties caused by external field sources,
A magnet with a smooth gold surface has better aesthetics,
They feature high magnetic induction at the operating surface, which improves attraction properties,
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...
Thanks to the option of precise shaping and customization to individualized solutions, NdFeB magnets can be modeled in a variety of shapes and sizes, which increases their versatility,
Huge importance in electronics industry – they are utilized in HDD drives, electric drive systems, medical equipment, and modern systems.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in miniature devices

Cons

Cons of neodymium magnets and ways of using them

To avoid cracks under impact, we suggest using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
We suggest a housing - magnetic mount, due to difficulties in realizing nuts inside the magnet and complicated forms.
Potential hazard resulting from small fragments of magnets can be dangerous, in case of ingestion, which becomes key in the context of child health protection. It is also worth noting that small components of these devices are able to disrupt the diagnostic process medical in case of swallowing.
Due to expensive raw materials, their price is relatively high,

Holding force characteristics

Maximum lifting force for a neodymium magnet – what contributes to it?

The load parameter shown represents the peak performance, recorded under optimal environment, specifically:

with the application of a yoke made of low-carbon steel, ensuring full magnetic saturation
possessing a thickness of at least 10 mm to ensure full flux closure
with an ideally smooth touching surface
with direct contact (without paint)
during pulling in a direction vertical to the mounting surface
at room temperature

Practical aspects of lifting capacity – factors

Holding efficiency is affected by specific conditions, including (from most important):

Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the nominal value.
Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
Material composition – different alloys attracts identically. High carbon content weaken the attraction effect.
Surface condition – smooth surfaces ensure maximum contact, which increases force. Uneven metal weaken the grip.
Thermal factor – hot environment reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Additionally, even a minimal clearance between the magnet and the plate reduces the holding force.

Precautions when working with neodymium magnets

Mechanical processing

Fire warning: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this risks ignition.

GPS Danger

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

Crushing force

Mind your fingers. Two powerful magnets will join instantly with a force of massive weight, crushing everything in their path. Be careful!

Danger to the youngest

Adult use only. Tiny parts pose a choking risk, causing severe trauma. Store away from kids and pets.

Fragile material

Neodymium magnets are ceramic materials, meaning they are very brittle. Impact of two magnets leads to them breaking into small pieces.

Operating temperature

Standard neodymium magnets (grade N) lose power when the temperature exceeds 80°C. This process is irreversible.

Magnetic media

Do not bring magnets close to a purse, computer, or TV. The magnetism can permanently damage these devices and erase data from cards.

Health Danger

Medical warning: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.

Allergy Warning

Certain individuals experience a sensitization to Ni, which is the typical protective layer for neodymium magnets. Prolonged contact may cause skin redness. We recommend use protective gloves.

Powerful field

Use magnets consciously. Their huge power can surprise even experienced users. Stay alert and do not underestimate their power.
