Pulling power decreases drastically with every subsequent millimeter of gap. Keep in mind that every additional insulation layer (e.g., contamination, paint, veneer) noticeably weakens the grip. Neodymiums hold most effectively at the point of direct contact; gap drastically cuts the force. Analyze how rapidly the parameters drop, when the magnet does not adhere flatly to the metal substrate. When designing the assembly, avoid unnecessary gaps.

This section indicates the estimated weight limit required to initiate the slippage of the magnet vertically on a upright steel plate (considering standard friction). The holding force is a function of the gap size between the magnet and the metal.

When mounting a holder on a upright plane (e.g., a fridge), it will only hold just approx. 20%-30% of its maximum pull force. Gravitational force as well as a weak degree of grip mean that magnets move down easier than they pop off the substrate. Planning a hanger? Remember that the shear force is significantly lower than the perpendicular breakaway force. On a slippery surface, the magnet will slide down under a much lighter load. Application of an anti-slip pad can drastically increase the grip.

A thin sheet is incapable of conduct the entire magnetic field, which wastes potential of the magnet. Should you install a neodymium to a thin surface, the field will pass right through and the attraction force will be weaker. To achieve 100% of this magnet's potential, you need a suitably thick element of metal. The saturation effect causes that on thin elements (e.g., car bodies), the magnet works worse. We advise picking the steel thickness according to the table below.

Classic neodymiums lose parameters after exceeding the maximum temperature. Watch out for overheating – high temperature can irreversibly damage this product. With every degree above norm, the neodymium's capacity momentarily lowers. Avoid using this product near heat sources exceeding its working range. Ignoring the limit will cause destruction of magnetism.

*Technical advisory: Temperature resistance is determined by both grade, and the Permeance Coefficient Pc. Flat magnets (low Pc) risk losing magnetic properties at lower temperatures compared to rod magnets. The danger warning in the table points to permanent field degradation for this specific geometry.

Two magnetic products interact from a much further distance than a magnet and steel setup. The setup of magnet-to-magnet produces a massive flux and a wider radius of performance. Want to build a strong closure? Apply two magnets instead of one magnet and a steel. Be careful that when bringing together two magnets, the impact force is massive. The levitation is marginally weaker than the connection force, but still large.
*The magnetic induction in repulsion mode is approximately ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
Attention: Calculations demonstrate shear force of a pair of same neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

Powerful magnet radiation is a serious hazard to IT equipment as well as medical implants. These NdFeB products generate a flux that prevents correct functioning of digital equipment. Notice: the unseen radiation passes through tissues and glass. Increased vigilance must be taken by people with cochlear implants and insulin pumps. Also at risk are: mechanical watches, car keys, speakers, and screens. Avoid contact with magnetic cards, HDD media, or sensitive navigation tools.

Table 8: Dynamics (kinetic energy) - collision effects

Magnetic elements are prone to chipping – a collision with steel risks their cracking. Pay attention to connection velocity – a neodymium left loose turns into a projectile. Kinetic force can destroy the magnet or dangerous crushing to skin. Always hold the magnet during mounting so it doesn't hit with great force against the steel surface. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Wear safety glasses when handling with large magnets.

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

The magnetic field penetrates through water without any losses. Buoyancy helps in lifting finds.

1. Wall mount (shear)

*Note: On a vertical wall, the magnet retains merely ~20% of its nominal pull.

2. Steel saturation

*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) = 0.23

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.

This product is a very powerful magnet in the shape of a plate made of NdFeB material, which, with dimensions of 42x20x5 mm and a weight of 31.5 g, guarantees the highest quality connection. This magnetic block with a force of 108.46 N is ready for shipment in 24h, allowing for rapid realization of your project. Additionally, its Ni-Cu-Ni coating protects it against corrosion in standard operating conditions, giving it an aesthetic appearance.

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. To separate the MPL 42x20x5 / 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. 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 generators and material handling systems. They work great as fasteners under tiles, wood, or glass. Customers often choose this model for hanging tools on strips and for advanced DIY and modeling projects, where precision and power count.

For mounting flat magnets MPL 42x20x5 / 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).

Standardly, the MPL 42x20x5 / N38 model is magnetized through the thickness (dimension 5 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 (42x20 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 42x20x5 mm, which, at a weight of 31.5 g, makes it an element with impressive energy density. It is a magnetic block with dimensions 42x20x5 mm and a self-weight of 31.5 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.

Strengths

Besides their remarkable field intensity, neodymium magnets offer the following advantages:

Their strength remains stable, and after around ten years it drops only by ~1% (theoretically),
They feature excellent resistance to magnetism drop when exposed to opposing magnetic fields,
Thanks to the glossy finish, the plating of nickel, gold-plated, or silver-plated gives an elegant appearance,
Magnetic induction on the working part of the magnet is exceptional,
Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
Due to the possibility of flexible shaping and adaptation to specialized projects, magnetic components can be modeled in a variety of shapes and sizes, which amplifies use scope,
Fundamental importance in modern technologies – they serve a role in mass storage devices, electric drive systems, diagnostic systems, also other advanced devices.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Disadvantages

Problematic aspects of neodymium magnets: weaknesses and usage proposals

Brittleness is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a strong case, which not only secures them against impacts but also increases their durability
We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
Due to limitations in creating nuts and complex forms in magnets, we propose using cover - magnetic mount.
Possible danger resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child safety. It is also worth noting that tiny parts of these products can disrupt the diagnostic process medical when they are in the body.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Lifting parameters

Optimal lifting capacity of a neodymium magnet – what contributes to it?

The load parameter shown refers to the peak performance, recorded under laboratory conditions, namely:

with the use of a yoke made of low-carbon steel, ensuring maximum field concentration
with a thickness of at least 10 mm
with a plane cleaned and smooth
without any clearance between the magnet and steel
during detachment in a direction perpendicular to the plane
in stable room temperature

Magnet lifting force in use – key factors

In real-world applications, the actual lifting capacity results from many variables, listed from crucial:

Air gap (betwixt the magnet and the metal), as even a very small distance (e.g. 0.5 mm) results in a drastic drop in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
Angle of force application – maximum parameter is reached only during perpendicular pulling. The force required to slide of the magnet along the plate is usually many times lower (approx. 1/5 of the lifting capacity).
Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
Material type – the best choice is pure iron steel. Cast iron may have worse magnetic properties.
Surface structure – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Roughness creates an air distance.
Thermal environment – heating the magnet results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.

Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate reduces the holding force.

H&S for magnets

ICD Warning

Health Alert: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have medical devices.

Hand protection

Big blocks can crush fingers in a fraction of a second. Do not place your hand betwixt two strong magnets.

Respect the power

Exercise caution. Rare earth magnets attract from a distance and connect with massive power, often faster than you can react.

Impact on smartphones

Navigation devices and smartphones are highly susceptible to magnetic fields. Direct contact with a strong magnet can permanently damage the internal compass in your phone.

Thermal limits

Avoid heat. Neodymium magnets are sensitive to temperature. If you require resistance above 80°C, look for HT versions (H, SH, UH).

Cards and drives

Avoid bringing magnets close to a wallet, laptop, or TV. The magnetism can permanently damage these devices and wipe information from cards.

Keep away from children

These products are not suitable for play. Swallowing several magnets can lead to them attracting across intestines, which poses a direct threat to life and necessitates immediate surgery.

Allergic reactions

Allergy Notice: The nickel-copper-nickel coating contains nickel. If redness happens, cease handling magnets and wear gloves.

Combustion hazard

Dust generated during machining of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.

Beware of splinters

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