Magnetic force decreases drastically per each millimeter of distance. Keep in mind that even the smallest gap (e.g., contamination, varnish, dust) noticeably reduces the pull force. Magnetic products hold most effectively in perfect adhesion; gap drastically cuts the force. Analyze how flashily the parameters fall, when the product does not adhere flatly to the steel surface. When planning the arrangement, discard additional spacers.

This section shows the theoretical holding capacity necessary to initiate the downward movement of the magnet down along a vertical steel plate (considering typical friction coefficient). This parameter is a function of the separation distance between the magnet and the surface.

Table 3: Vertical assembly (sliding) - vertical pull
MPL 10x10x4 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.93 kg / 2.05 lbs 930.0 g / 9.1 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.62 kg / 1.37 lbs 620.0 g / 6.1 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.31 kg / 0.68 lbs 310.0 g / 3.0 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.55 kg / 3.42 lbs 1550.0 g / 15.2 N

When mounting a element on a vertical plane (e.g., a fridge), it will only hold only about 20%-30% of nominal attraction strength. Gravitational force as well as a weak degree of grip influence the fact that holders move down faster than they pop off the substrate. Want to create a vertical fastening? Remember that the shear force is much weaker than the maximum static pull force. On a painted metal, the holder will slip down under a noticeably lighter weight. Using a rubber pad can significantly increase the grip.

12 mm	100%	3.10 kg / 6.83 lbs 3100.0 g / 30.4 N

A thin sheet cannot take in the full magnetic flux, which squanders power of the magnet. If you install a neodymium to a weak sheet, the flux will pass right through and the pull force will drop sharply. To achieve 100% of this neodymium's potential, you need a suitably thick backing of metal. The saturation effect causes that on thin elements (e.g., car bodies), the product shows lower pull force. We advise picking the steel cross-section from these parameters.

Classic neodymiums irreversibly lose parameters above the temperature limit. Protect against heat – excessive heat can permanently destroy this product. As the temperature rises, the magnet's power briefly decreases. Avoid using this product near heat sources higher than its working range. Exceeding the critical threshold will cause irreversible degradation of magnetic properties.

*Technical advisory: Thermal stability depends not only on the material grade, but also on the magnet's shape. Thin magnets (pancake types) may lose charge permanently sooner compared to rod magnets. The danger warning in the table indicates a risk of irreversible loss for this particular item.

Two strong neodymiums interact from a wider radius than a magnet and steel combination. The setup of two magnets generates a stronger field and a wider radius of action. Want to build a strong closure? Apply two magnets instead of a neodymium and a steel. Remember that when connecting a pair of magnets, the collision energy is massive. The levitation is slightly lower than the connection force, but still impressive.
*Flux density for N-N configuration is approximately ~0 Gs in the exact middle between the magnets (resulting from vector opposition).
Important: Figures demonstrate friction force of dual identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

Powerful magnet radiation is a serious hazard to electronics as well as pacemakers. These NdFeB products generate a flux that destroys function of sensitive medical devices. Notice: the unseen radiation acts through matter and housings. Increased vigilance must be taken by people with hearing aids and drug dispensers. The risk also applies to: mechanical watches, car keys, speakers, and screens. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

Table 8: Dynamics (cracking risk) - warning

Neodymium magnets are delicate – a violent impact against metal can result in shattering. Watch the impact speed – a magnet released freely turns into a projectile. Kinetic force can destroy the magnet or painful pinches to fingers. Always hold the magnet during installation so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h means shattering of the neodymium. Wear safety glasses when playing with large magnets.

Water (riverbed)	3.55 kg (+0.45 kg buoyancy gain)	+14.5%

Rust risk: 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. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Sliding resistance

*Caution: On a vertical wall, the magnet holds merely a fraction of its perpendicular strength.

2. Steel saturation

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

3. Heat tolerance

*For standard magnets, 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) = 0.46

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.

Model MPL 10x10x4 / N38 features a flat shape and industrial pulling force, making it an ideal solution for building separators and machines. This rectangular block with a force of 30.39 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.

The key to success is shifting the magnets along their largest connection plane (using e.g., the edge of a table), which is easier than trying to tear them apart directly. Watch your fingers! Magnets with a force of 3.10 kg can pinch very hard and cause hematomas. Using a screwdriver risks destroying the coating and permanently cracking the magnet.

They constitute a key element in the production of generators and material handling systems. They work great as fasteners 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. For lighter applications or mounting on smooth surfaces, branded foam tape (e.g., 3M VHB) will work, provided the surface is perfectly degreased. 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. In practice, this means that this magnet has the greatest attraction force on its main planes (10x10 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: 10 mm (length), 10 mm (width), and 4 mm (thickness). It is a magnetic block with dimensions 10x10x4 mm and a self-weight of 3 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Strengths as well as weaknesses of rare earth magnets.

Pros

In addition to their long-term stability, neodymium magnets provide the following advantages:

They do not lose power, even during approximately ten years – the drop in lifting capacity is only ~1% (theoretically),
Neodymium magnets are extremely resistant to loss of magnetic properties caused by magnetic disturbances,
Thanks to the shiny finish, the layer of Ni-Cu-Ni, gold, or silver-plated gives an professional appearance,
Neodymium magnets deliver maximum magnetic induction on a small area, which ensures high operational effectiveness,
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 flexibility in forming and the ability to adapt to individual projects,
Significant place in advanced technology sectors – they are used in data components, motor assemblies, diagnostic systems, as well as industrial machines.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which allows their use in small systems

Weaknesses

Problematic aspects of neodymium magnets and proposals for their use:

They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape as well as 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
Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
Due to limitations in producing threads and complicated forms in magnets, we recommend using casing - magnetic holder.
Potential hazard related to microscopic parts of magnets pose a threat, if swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, small components of these products can complicate diagnosis medical in case of swallowing.
With mass production the cost of neodymium magnets is a challenge,

Pull force analysis

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

The lifting capacity listed is a measurement result performed under specific, ideal conditions:

on a base made of structural steel, perfectly concentrating the magnetic flux
whose thickness reaches at least 10 mm
with an polished touching surface
under conditions of ideal adhesion (surface-to-surface)
for force acting at a right angle (pull-off, not shear)
in temp. approx. 20°C

Magnet lifting force in use – key factors

Holding efficiency impacted by specific conditions, such as (from priority):

Space between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
Loading method – catalog parameter refers to detachment vertically. When slipping, the magnet holds much less (often approx. 20-30% of nominal force).
Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
Chemical composition of the base – low-carbon steel gives the best results. Alloy admixtures reduce magnetic properties and lifting capacity.
Smoothness – ideal contact is possible only on polished steel. Rough texture create air cushions, reducing force.
Thermal factor – high temperature weakens pulling force. Too high temperature can permanently demagnetize the magnet.

Lifting capacity testing was conducted 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. Moreover, even a small distance between the magnet and the plate lowers the load capacity.

Safety rules for work with NdFeB magnets

Threat to electronics

Powerful magnetic fields can destroy records on payment cards, HDDs, and other magnetic media. Stay away of min. 10 cm.

Handling rules

Before starting, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Think ahead.

No play value

Adult use only. Tiny parts pose a choking risk, causing serious injuries. Keep out of reach of children and animals.

Impact on smartphones

An intense magnetic field disrupts the operation of magnetometers in phones and GPS navigation. Do not bring magnets close to a device to avoid breaking the sensors.

Nickel allergy

Certain individuals have a contact allergy to nickel, which is the common plating for neodymium magnets. Prolonged contact may cause skin redness. We strongly advise wear safety gloves.

Do not overheat magnets

Keep cool. Neodymium magnets are susceptible to heat. If you need operation above 80°C, ask us about special high-temperature series (H, SH, UH).

Bone fractures

Protect your hands. Two large magnets will snap together immediately with a force of massive weight, destroying everything in their path. Exercise extreme caution!

ICD Warning

Warning for patients: Strong magnetic fields affect medical devices. Keep at least 30 cm distance or ask another person to work with the magnets.

Magnets are brittle

Watch out for shards. Magnets can fracture upon violent connection, launching shards into the air. Eye protection is mandatory.

Mechanical processing

Fire hazard: Neodymium dust is explosive. Do not process magnets in home conditions as this risks ignition.
