Grip strength weakens significantly with every subsequent millimeter of distance. Keep in mind that every additional insulation layer (e.g., dirt, paint, rust) strongly reduces the pull force. Magnetic products hold strongest during direct contact; distance kills the power. Notice how rapidly the pull force drop, when the magnet does not adhere tightly to the metal substrate. When designing the assembly, avoid unnecessary gaps.

The following data defines the approximate holding capacity required to cause the sliding of the magnet downwards on a vertical steel wall (considering typical friction coefficient). This value varies with the air gap between the magnet and the surface.

Table 3: Wall mounting (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 upright surface (e.g., a car body), it will maintain barely approx. 20%-30% of its maximum pull force. Gravity as well as a weak degree of grip cause that products move down faster than they pop off the substrate. Want to create a vertical fastening? Remember that the shear force is noticeably lower than the perpendicular breakaway force. On a smooth steel, the holder will give way down under a much lighter load. Application of an anti-slip coating can effectively increase the grip.

A too thin steel is unable to take in the entire magnetic field, which squanders power of the magnet. If you install a neodymium to a weak sheet, the flux will pass right through and the holding will be smaller. To achieve full efficiency of this neodymium's power, you need a suitably thick backing of steel. The saturation phenomenon causes that on sheet metal structures (e.g., appliance housings), the product works worse. We advise picking the steel dimension based on the following data.

Standard neodymium magnets irreversibly lose power past the thermal threshold. Protect against heat – excessive heat can permanently destroy this product. With increasing heat, the neodymium's force briefly decreases. Do not use this magnet close to ovens exceeding its working range. Ignoring the limit will lead to irreversible degradation of magnetism.

*Technical advisory: Heat tolerance depends not only on the material grade, as well as the dimension ratios. Low-profile magnets (low permeance coefficient) are more susceptible to demagnetization under lower heat stress compared to rod magnets. Red status in the table points to a risk of irreversible loss for this particular item.

Two magnets attract each other from a significantly greater distance than a neodymium and metal setup. The connection of two magnets creates a more powerful interaction and a further horizon of performance. Want to build a powerful holder? Use a pair of magnets instead of a neodymium and a steel. Exercise caution that when attracting two neodymiums, the pinch force is huge. The levitation is slightly lower than the attraction, but still impressive.
*Flux density for N-N configuration drops to ~0 Gs at the geometric center between the magnets (resulting from vector opposition).
* Calculations demonstrate shear force of two matching magnets (friction ~0.15 for Ni-Ni plating).

Powerful magnet radiation is a serious hazard to electronic devices and medical implants. These magnets generate a flux that prevents correct functioning of digital equipment. Notice: the unseen radiation acts through matter and plastic. Special caution must be taken by people with cochlear implants and drug dispensers. The risk also applies to: mechanical watches, remotes, membranes, and displays. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

Magnetic elements are delicate – a collision with steel can result in shattering. Control the attraction moment – a neodymium left loose becomes dangerous. Impact energy can destroy the magnet or dangerous crushing to skin. Be sure to control the product during mounting so it doesn't hit with great force against the metal. A collision at high speed almost guarantees destruction of the magnet. Use safety goggles when working with powerful specimens.

The magnetic field penetrates through water without any losses. However, remember the water resistance when pulling the rope quickly.

1. Vertical hold

*Note: On a vertical surface, the magnet retains just ~20% of its max power.

2. Plate thickness effect

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

3. Temperature resistance

*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) = 0.46

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.

Model MPL 10x10x4 / N38 features a flat shape and professional pulling force, making it a perfect solution for building separators and machines. As a magnetic bar with high power (approx. 3.10 kg), this product is available immediately from our warehouse in Poland. The durable anti-corrosion layer ensures a long lifespan in a dry environment, protecting the core from oxidation.

Separating block magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. To separate the MPL 10x10x4 / N38 model, firmly slide one magnet over the edge of the other until the attraction force decreases. We recommend care, because after separation, the magnets may want to violently snap back together, which threatens pinching the skin. 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. Thanks to the flat surface and high force (approx. 3.10 kg), they are ideal as closers in furniture making and mounting elements in automation. Customers often choose this model for hanging tools on strips and for advanced DIY and modeling projects, where precision and power count.

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. Remember to clean and degrease the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

Standardly, the MPL 10x10x4 / N38 model is magnetized axially (dimension 4 mm), which means that the N and S poles are located on its largest, flat surfaces. 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.

This model is characterized by dimensions 10x10x4 mm, which, at a weight of 3 g, makes it an element with impressive energy density. 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.

Advantages as well as disadvantages of Nd₂Fe₁₄B magnets.

Advantages

Apart from their strong magnetic energy, neodymium magnets have these key benefits:

They retain full power for almost ten years – the drop is just ~1% (according to analyses),
They feature excellent resistance to magnetism drop due to opposing magnetic fields,
Thanks to the smooth finish, the coating of nickel, gold, or silver gives an modern appearance,
They are known for high magnetic induction at the operating surface, making them more effective,
Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for operation at temperatures reaching 230°C and above...
In view of the possibility of free shaping and customization to custom needs, NdFeB magnets can be produced in a wide range of geometric configurations, which makes them more universal,
Huge importance in modern technologies – they are utilized in data components, electromotive mechanisms, advanced medical instruments, and modern systems.
Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which allows their use in small systems

Limitations

Disadvantages of neodymium magnets:

To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
Neodymium magnets decrease their power 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
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 and corrosion.
Due to limitations in producing threads and complex shapes in magnets, we recommend using casing - magnetic mechanism.
Health risk related to microscopic parts of magnets pose a threat, if swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, small components of these magnets can complicate diagnosis medical when they are in the body.
Due to neodymium price, their price exceeds standard values,

Lifting parameters

Maximum lifting force for a neodymium magnet – what it depends on?

Breakaway force was defined for ideal contact conditions, including:

on a base made of mild steel, perfectly concentrating the magnetic field
whose thickness is min. 10 mm
with an polished contact surface
with zero gap (no coatings)
during detachment in a direction perpendicular to the plane
in stable room temperature

Magnet lifting force in use – key factors

Bear in mind that the working load will differ depending on elements below, starting with the most relevant:

Clearance – existence of any layer (rust, tape, air) acts as an insulator, which reduces capacity rapidly (even by 50% at 0.5 mm).
Direction of force – highest force is reached only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is usually several times lower (approx. 1/5 of the lifting capacity).
Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
Metal type – different alloys attracts identically. Alloy additives worsen the attraction effect.
Plate texture – ground elements guarantee perfect abutment, which improves field saturation. Rough surfaces weaken the grip.
Temperature influence – hot environment reduces magnetic field. Too high temperature can permanently demagnetize the magnet.

Lifting capacity was assessed by applying a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under parallel forces the lifting capacity is smaller. In addition, even a minimal clearance between the magnet’s surface and the plate lowers the load capacity.

Safety rules for work with NdFeB magnets

This is not a toy

These products are not toys. Eating a few magnets can lead to them attracting across intestines, which poses a direct threat to life and requires immediate surgery.

Allergic reactions

Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If redness appears, immediately stop working with magnets and use protective gear.

Data carriers

Intense magnetic fields can destroy records on credit cards, hard drives, and storage devices. Stay away of min. 10 cm.

Shattering risk

Neodymium magnets are ceramic materials, which means they are fragile like glass. Collision of two magnets will cause them cracking into shards.

Crushing risk

Watch your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, crushing anything in their path. Be careful!

Mechanical processing

Machining of neodymium magnets poses a fire hazard. Neodymium dust reacts violently with oxygen and is difficult to extinguish.

Do not overheat magnets

Watch the temperature. Heating the magnet above 80 degrees Celsius will ruin its properties and pulling force.

GPS Danger

GPS units and mobile phones are extremely susceptible to magnetism. Close proximity with a strong magnet can permanently damage the internal compass in your phone.

Caution required

Before use, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.

Warning for heart patients

People with a ICD should keep an large gap from magnets. The magnetic field can disrupt the functioning of the implant.

Caution! Details about hazards in the article: Safety of working with magnets.
