Pulling power weakens significantly with every mm of gap. Remember that even a very thin break (e.g., contamination, varnish, rust) significantly diminishes the holding power. Magnetic products hold strongest at the point of direct contact; distance weakens the force. Observe how rapidly the parameters drop, when the product does not adhere tightly to the steel surface. When planning the assembly, eliminate additional spacers.

The table below shows the estimated weight limit necessary to cause the shifting of the magnet downwards against a upright steel wall (assuming typical friction). This value varies with the separation distance between the magnet and the surface.

Table 3: Vertical assembly (shearing) - vertical pull
MPL 20x10x2 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.56 kg / 1.24 pounds 564.0 g / 5.5 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.38 kg / 0.83 pounds 376.0 g / 3.7 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.19 kg / 0.41 pounds 188.0 g / 1.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.94 kg / 2.07 pounds 940.0 g / 9.2 N

When mounting a magnet on a upright wall (e.g., a car body), it will maintain only approx. 20%-30% of its maximum pull force. Gravity and a low friction coefficient cause that magnets move down easier than they detach. Want to create a hanger? Remember that the sliding force is significantly lower than the maximum static pull force. On a smooth steel, the element will slip down under a noticeably lighter load. Utilizing a rubberized pad can effectively raise the stability.

12 mm	100%	1.88 kg / 4.14 pounds 1880.0 g / 18.4 N

A too thin steel is incapable of take in the entire magnetic field, which wastes potential of the magnet. Should you mount a strong magnet to a thin surface, the magnetism will pass right through and the pull force will drop sharply. To achieve 100% of this magnet's potential, you need a suitably thick element of metal. The material oversaturation means that on sheet metal structures (e.g., thin profiles), the holder shows lower pull force. We advise picking the steel dimension based on the following data.

Standard neodymium magnets irreversibly lose power above the temperature limit. Avoid high temperatures – excessive heat can irreversibly demagnetize this product. With every degree above norm, the magnet's capacity briefly lowers. Avoid using this magnet near heat sources higher than its working range. Exceeding the critical threshold will lead to permanent loss of magnetic properties.

*Engineering note: Heat tolerance depends not only on the material grade, but also on the magnet's shape. Thin magnets (low permeance coefficient) risk losing magnetic properties under lower heat stress compared to rod magnets. The danger warning in the table signals a risk of irreversible loss for this particular item.

Two magnetic products attract each other from a much further distance than a neodymium and metal combination. The setup of two magnets generates a stronger field and a larger range of performance. Designing a solid fastener? Use a pair of magnets instead of one magnet and a steel. Exercise caution that when connecting a pair of magnets, the pinch force is massive. The repulsion force is slightly lower than the attraction, but still significant.
*The magnetic induction in repulsion mode is approximately ~0 Gs at the geometric center between the magnets (resulting from vector opposition).
Important: Figures apply to sliding force of two identical magnets (friction ~0.15 for Ni-Ni coating).

Table 7: Protective zones (implants) - precautionary measures
MPL 20x10x2 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	5.5 cm

A strong magnetic field poses a real danger to electronic devices as well as pacemakers. These neodymiums produce a field that disrupts operation of sensitive medical devices. Remember: the invisible magnetic field acts through matter and housings. Exceptional care must be taken by people with hearing aids and insulin pumps. Also at risk are: automatic timepieces, car keys, membranes, and displays. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Table 8: Impact energy (cracking risk) - collision effects

Magnetic elements are very brittle – a strong collision with metal can result in shattering. Pay attention to connection velocity – a neodymium left loose turns into a projectile. Kinetic force can destroy the magnet or dangerous crushing to fingers. Always hold the magnet during installation so it doesn't hit with great force against the steel surface. A collision at high speed ends with a crack of the magnet. Wear eye protection when handling with powerful specimens.

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

1. Shear force

*Warning: On a vertical surface, the magnet retains just a fraction of its max power.

2. Steel saturation

*Thin metal sheet (e.g. computer case) significantly limits the holding force.

3. Temperature resistance

*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) = 0.19

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 a very powerful magnet in the shape of a plate made of NdFeB material, which, with dimensions of 20x10x2 mm and a weight of 3 g, guarantees the highest quality connection. This rectangular block with a force of 18.44 N is ready for shipment in 24h, allowing for rapid realization of your project. 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 20x10x2 / 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.

They constitute a key element in the production of wind generators and material handling systems. They work great as invisible mounts 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).

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: 20 mm (length), 10 mm (width), and 2 mm (thickness). The key parameter here is the holding force amounting to approximately 1.88 kg (force ~18.44 N), which, with such a flat shape, proves the high power of the material. The product meets the standards for N38 grade magnets.

Strengths as well as weaknesses of rare earth magnets.

Strengths

In addition to their magnetic efficiency, neodymium magnets provide the following advantages:

Their magnetic field remains stable, and after approximately 10 years it drops only by ~1% (theoretically),
They have excellent resistance to magnetic field loss when exposed to opposing magnetic fields,
The use of an aesthetic coating of noble metals (nickel, gold, silver) causes the element to present itself better,
Neodymium magnets achieve maximum magnetic induction on a contact point, which allows for strong attraction,
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...
Thanks to flexibility in forming and the capacity to adapt to individual projects,
Wide application in high-tech industry – they serve a role in computer drives, motor assemblies, precision medical tools, and other advanced devices.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which makes them useful in small systems

Weaknesses

What to avoid - cons of neodymium magnets and proposals for their use:

To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their power 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
Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
Due to limitations in realizing nuts and complicated forms in magnets, we recommend using casing - magnetic holder.
Possible danger related to microscopic parts of magnets are risky, in case of ingestion, which gains importance in the context of child safety. Furthermore, small components of these products are able to be problematic in diagnostics medical after entering the body.
Due to neodymium price, their price is higher than average,

Lifting parameters

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

The force parameter is a result of laboratory testing executed under the following configuration:

using a plate made of mild steel, acting as a ideal flux conductor
possessing a thickness of min. 10 mm to ensure full flux closure
with an ideally smooth contact surface
without any insulating layer between the magnet and steel
for force applied at a right angle (in the magnet axis)
in temp. approx. 20°C

Magnet lifting force in use – key factors

Holding efficiency impacted by working environment parameters, including (from priority):

Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
Load vector – highest force is available only during pulling at a 90° angle. The shear force of the magnet along the plate is typically several times lower (approx. 1/5 of the lifting capacity).
Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of converting into lifting capacity.
Metal type – different alloys attracts identically. Alloy additives worsen the attraction effect.
Smoothness – full contact is possible only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and in frost gain strength (up to a certain limit).

Lifting capacity testing was performed on a smooth plate of suitable thickness, under a perpendicular pulling force, however under parallel forces the lifting capacity is smaller. In addition, even a slight gap between the magnet’s surface and the plate lowers the holding force.

Safety rules for work with NdFeB magnets

Health Danger

For implant holders: Strong magnetic fields affect electronics. Maintain minimum 30 cm distance or ask another person to work with the magnets.

Crushing force

Big blocks can break fingers instantly. Never put your hand between two strong magnets.

Metal Allergy

Studies show that nickel (standard magnet coating) is a common allergen. For allergy sufferers, avoid touching magnets with bare hands and choose encased magnets.

Mechanical processing

Fire warning: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this may cause fire.

Phone sensors

Be aware: neodymium magnets produce a field that disrupts precision electronics. Maintain a separation from your mobile, device, and navigation systems.

Safe distance

Powerful magnetic fields can erase data on payment cards, hard drives, and other magnetic media. Keep a distance of at least 10 cm.

Handling guide

Use magnets consciously. Their huge power can surprise even professionals. Be vigilant and do not underestimate their power.

Eye protection

Neodymium magnets are ceramic materials, meaning they are fragile like glass. Impact of two magnets leads to them breaking into small pieces.

Heat warning

Watch the temperature. Exposing the magnet to high heat will destroy its magnetic structure and pulling force.

Adults only

Absolutely store magnets out of reach of children. Risk of swallowing is high, and the consequences of magnets clamping inside the body are very dangerous.
