Pulling power decreases sharply with every subsequent millimeter of spacing. Remember that even a microscopic distance (e.g., dirt, paint, dust) strongly diminishes the holding power. Magnets work strongest at the point of direct contact; gap drastically cuts the force. Observe how rapidly the load capacity drop, when the product does not touch flatly to the metal substrate. When designing the assembly, avoid additional spacers.

The following data indicates the estimated force required to cause the slippage of the magnet vertically against a vertical steel plate (considering standard friction coefficient). This value varies with the distance between the magnet and the metal.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MPL 5x5x2 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.23 kg / 0.51 LBS 231.0 g / 2.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.15 kg / 0.34 LBS 154.0 g / 1.5 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.08 kg / 0.17 LBS 77.0 g / 0.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.39 kg / 0.85 LBS 385.0 g / 3.8 N

When placing a magnet on a vertical wall (e.g., a fridge), it you can count on just approx. 20%-30% of nominal attraction strength. Gravity as well as a weak degree of grip influence the fact that magnets slide down easier than they pull off. Designing a wall mount? Note that the shear force is noticeably lower than the maximum static pull force. On a painted metal, the magnet will give way down under a much lighter weight. Utilizing a rubberized layer can significantly increase the grip.

A thin sheet cannot take in the entire magnetic field, which wastes potential of the magnet. Should you attach a powerful product to a thin surface, the magnetism will penetrate right through and the holding will be smaller. To squeeze 100% of this neodymium's potential, you require a sufficiently solid piece of steel. The material oversaturation means that on thin elements (e.g., appliance housings), the product works worse. We advise picking the steel thickness according to the table below.

Classic neodymiums lose power after exceeding the maximum temperature. Protect against heat – excessive heat can permanently destroy this product. As the temperature rises, the magnet's force momentarily drops. Avoid using this product in hot environments exceeding its safe range. Too high temperature will lead to destruction of magnetic properties.

*Technical advisory: Thermal stability depends not only on the material grade, and the Permeance Coefficient Pc. Thin magnets (pancake types) may lose charge permanently sooner compared to rod magnets. The danger warning in the table points to a risk of irreversible loss for this specific geometry.

Two magnetic products attract each other from a significantly greater distance than a magnet and steel combination. The connection of magnet-to-magnet creates a more powerful interaction and a further horizon of performance. Planning to create a powerful holder? Use a pair of magnets instead of one magnet and a steel. Exercise caution that when connecting a pair of magnets, the impact force is extreme. The repulsion force is marginally weaker than the attraction, but still large.
*The magnetic induction between like poles drops to ~0 Gs at the geometric center between the magnets (due to field cancellation).
* Estimates demonstrate sliding force of dual same magnets (friction coefficient ~0.15 for Ni-Ni coating).

Extremely neodym field poses a large risk to IT equipment as well as medical implants. These NdFeB products generate a field that destroys function of digital equipment. Remember: the invisible magnetic field acts through matter and glass. Increased vigilance must be taken by people with cochlear implants and drug dispensers. Influence will be felt by: automatic timepieces, car keys, membranes, and displays. Do not bring the product near payment cards, hard drives, or sensitive navigation tools.

Neodymium magnets are very brittle – a violent impact against metal risks their cracking. Control the attraction moment – a neodymium left loose becomes dangerous. Striking energy can destroy the magnet or painful pinches to fingers. Always hold the magnet 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 eye protection when handling with powerful specimens.

Warning: 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. However, remember the water resistance when pulling the rope quickly.

1. Sliding resistance

*Note: On a vertical wall, the magnet retains merely approx. 20-30% of its perpendicular strength.

2. Plate thickness effect

*Thin metal sheet (e.g. computer case) severely weakens the holding force.

3. Temperature resistance

*For N38 material, 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.

SM 25x175 [2xM8] / N42 - magnetic separator

467.40 ZŁ brutto / pcs

Component MPL 5x5x2 / N38 features a flat shape and industrial pulling force, making it a perfect solution for building separators and machines. As a magnetic bar with high power (approx. 0.77 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.

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 0.77 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 wind generators and material handling systems. Thanks to the flat surface and high force (approx. 0.77 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.

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).

Standardly, the MPL 5x5x2 / N38 model is magnetized through the thickness (dimension 2 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. This is the most popular configuration for block magnets used in separators and holders.

This model is characterized by dimensions 5x5x2 mm, which, at a weight of 0.38 g, makes it an element with impressive energy density. It is a magnetic block with dimensions 5x5x2 mm and a self-weight of 0.38 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Advantages and disadvantages of neodymium magnets.

Pros

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

They have constant strength, and over around ten years their performance decreases symbolically – ~1% (in testing),
Magnets perfectly protect themselves against loss of magnetization caused by foreign field sources,
By using a decorative coating of nickel, the element has an proper look,
Magnets possess impressive magnetic induction on the surface,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
In view of the possibility of precise shaping and adaptation to individualized requirements, neodymium magnets can be manufactured in a variety of shapes and sizes, which amplifies use scope,
Wide application in future technologies – they are commonly used in data components, brushless drives, advanced medical instruments, also other advanced devices.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Disadvantages

Characteristics of disadvantages of neodymium magnets: application proposals

Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a steel housing, which not only secures them against impacts but also raises their durability
When exposed to high temperature, neodymium magnets suffer 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
Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture
We recommend cover - magnetic mechanism, due to difficulties in producing nuts inside the magnet and complicated forms.
Possible danger to health – tiny shards of magnets are risky, when accidentally swallowed, which is particularly important in the context of child safety. Additionally, small components of these products are able to complicate diagnosis medical when they are in the body.
With large orders the cost of neodymium magnets is economically unviable,

Holding force characteristics

Maximum magnetic pulling force – what contributes to it?

The declared magnet strength concerns the limit force, measured under laboratory conditions, namely:

on a block made of mild steel, perfectly concentrating the magnetic flux
possessing a thickness of at least 10 mm to ensure full flux closure
with a surface free of scratches
under conditions of ideal adhesion (metal-to-metal)
during pulling in a direction vertical to the mounting surface
at room temperature

Practical aspects of lifting capacity – factors

In practice, the actual lifting capacity is determined by several key aspects, ranked from most significant:

Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
Substrate thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
Material type – ideal substrate is pure iron steel. Cast iron may attract less.
Smoothness – full contact is obtained only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
Thermal factor – hot environment reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity was measured with the use of a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, in contrast under parallel forces the load capacity is reduced by as much as 5 times. Moreover, even a slight gap between the magnet and the plate lowers the load capacity.

Safety rules for work with NdFeB magnets

Safe operation

Handle magnets with awareness. Their huge power can surprise even professionals. Stay alert and do not underestimate their force.

Do not drill into magnets

Mechanical processing of NdFeB material poses a fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.

Medical interference

Warning for patients: Powerful magnets affect electronics. Keep minimum 30 cm distance or ask another person to handle the magnets.

Eye protection

Despite the nickel coating, neodymium is brittle and cannot withstand shocks. Do not hit, as the magnet may shatter into hazardous fragments.

Threat to navigation

An intense magnetic field interferes with the functioning of compasses in smartphones and navigation systems. Maintain magnets close to a device to prevent breaking the sensors.

Keep away from computers

Powerful magnetic fields can erase data on payment cards, HDDs, and storage devices. Keep a distance of at least 10 cm.

Permanent damage

Keep cool. Neodymium magnets are sensitive to heat. If you need resistance above 80°C, inquire about special high-temperature series (H, SH, UH).

Nickel allergy

A percentage of the population have a contact allergy to Ni, which is the typical protective layer for NdFeB magnets. Extended handling might lead to a rash. It is best to use safety gloves.

This is not a toy

Strictly store magnets away from children. Risk of swallowing is significant, and the consequences of magnets connecting inside the body are very dangerous.

Bone fractures

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

Danger! Learn more about risks in the article: Magnet Safety Guide.
